In the age of smart TVs that requires user agreements and have ads injected into the UI, using an NEC digital signage display for my home TV -- no garbage, no frills, virtually indestructible panel -- has been bliss. At my old workplace, there was a set of NEC MultiSync panels in the lobby, displaying the same static map and welcome message, 24/7/365, for as long as anybody could remember. I checked their uptimes one day and found they were both identical: 32,767 hours. They hit the integer limit years ago and just stopped counting. Still looked and functioned like new.
digital sinage displays have got to be the best discovery i've made when looking for "modern dumb TVs", got myself a 70" version of the NEC for an equivelant of 300USD and using the PIP mode to watch some shows while playing on my xbox has been really fun
DUDE. OK so hear me out, I promise this is going somewhere. Years ago one of our clients spent a HUGE amount of money on a ~80 inch smartboard TV for their conference room that used an OPS Module. When we ordered it and the module, they sent the wrong module and when we called them they shipped the correct one. They told us to keep it. I'll never understand why. I tried to sell it on eBay for quite some time but got no takers. I'm pretty sure it's this same connector/standard but have to go look tomorrow. I think we still have it, and my boss would almost certainly let me send it to you. OKOKOK here's the thing about it. This particular module is not a "little guy" in the way you think. This particular module uses AN INTEL COMPUTE CARD, and HAS ONE IN THE BOX with it. For once I'm excited to check the shelves at work. Will report back to these comments if I'm right about it being a normal OPS module.

The really seems to be a sharp divide, half of people say these things never get used, the other half said they couldn't live without them. I'm glad to hear that a lot of them are getting used!
@ not being a teacher I just assume they are good for math and garbage die anything else. Even when I was in school the projectors only got used by math teachers.
@@CathodeRayDude Teachers are sometimes extremely set in their ways. They also will hold on to tech from decades ago, because it still works even when a better solution presents itself. As I said in my earlier post the best way to get them to use this stuff is to not give them another option. Rip out(or in most cases since it's cheaper just mount this on top of it) their traditional white board and they will have no other option. As someone who has worked in and around education for over a decade its frustrating to deal with someone who couldn't program the clock on their VCR bitd, but is also responsible for educating young minds. Technology literacy is just as important as actual literacy yet there are still teachers you have to drag kicking and screaming out of the 90s.
@@CathodeRayDude This seems pretty much true to my experience. I was at the end of primary school during the first wave of digital whiteboards starting to take off (around 2004-06, when they were replacing OHPs with PC projectors instead, and thus the terrible calibration experience of syncing up some kind of touch/pen-sensitive canvas with a projector that try as you might you can never quite keystone correctly), and there always seemed to be a roughly 50/50 divide between the teachers who used their digital whiteboards AS digital whiteboards, and those who only used them as they would do a PC projector with no whiteboard functionality, i.e. effectively as a more complicated OHP. In my secondary school, we didn't have many digital whiteboards, (though there definitely were SOME). most classrooms just had PC projectors and pull-down screens (or just projected ONTO a standard whiteboard, so would often annotate the display directly using dry-wipe), though some classrooms also had document cameras hooked up to their projector to TRULY recreate the OHP experience.
@CathodeRayDude some are also SMART Technologies SMART boards, a projector with a laser that tracks if something crosses the display It's basically projector + crappy "touch screen" bolted to computer = crappo

28:21 Having a screen WITHOUT the tuner allows you to avoid paying TV "tax" in some countries.
หลายเดือนก่อน +17
Came here to say this. Many countries fund(ed) their public broadcast system via television (and before that radio) fee that was often "per tuner". Thus entities who needed only the display didn't want tuners included.
Your line about nerds wanting the best possible commercial grade equipment just to mess around with and do absolutely nothing useful is painfully accurate. Signed, a person who just spent 6 months learning to repair IBM Selectric typewriters, got one fully restored after countless painful setbacks, and now uses it to do occasional journaling and type about... my sweet working IBM Selectric typewriter. "This sure is better than a word processor. No distractions here! It only takes a bachelor's degree worth of knowledge to keep it working, so much fun!"
I don't remember it being specifically called out, but obviously inferred, the fact that the screen could run for a decade or two at a shot in continuously on state, w/o losing it's backlight at 2 years, kind of sold me on the idea. I'll be watching for some on e-bay when the latest batch of 32" TV's die in a year or two. Did a search this morning, and found half a dozen e328 models ranging from $129 to $299 available as buy it now or best offer. No available funds at the moment, so holding off on those. Pretty sure that more will show up.
@@RNMSC We got a Samsung Digital Signage display for a project at work, the thing is rated for 24/7 operation for like 50000 hours MTBF. Literally over 5 years of continuous nonstop usage. Pro gear is on another level altogether. Then again you feel it with a tap on the panel. A normal household LCD feels like it will shatter with a tap (and will with a slightly harder hit), that thing feels like it's twice as thick at least. It just doesn't flex the glass. And it's just a plastic frame one, none of that super rugged extra heavy steel casing stuff like the NEC Gravis showed here.
my high school started installing the newest version of those things during my senior year. they had an account system for like multiple teachers and everything. and I was the person who got told by the teachers to fix the things when the inputs eventually came unplugged. I have also plugged multiple ancient dvd drives into them because I was the techy kid. they used basically none of the inbuilt features outside of the screencast and basically used them as overhead projector replacements. gotta love how state money went to buying them instead of fixing the mold problem in my rundown rural high school from the 70's.
So, your School couldn't have bought Polyboard or Promethean or Smart or LG Pentouch or the Microsoft Whiteboard or Google Jam Board or the Samsung (whatever they call them now) or Vibe board or Viewsonic or Benq boards.
My School as did the same thing with the Promethean Activ Titaniums. At least they bought the lower storage ones that were 64 GBs and not expansion cards running ChromeOS or Windows 10/11 IOT they were all 65 inch versions from my memory. They never used all the features, just Teams installed from the Google Play Store. And my School had HP USFFs tons of them they never used them and I connected them for them. So, glad USB Plug and Play exists I was not going to fight with User Account Control. They also had Surfaces Brand new Never Used and a whole lot more. But, I gotta admit you could easily get into the "secret service settings" The display's mainboard UI and enable 3D since they also have 3D Glasses from the Smart Projectors (Our Old ones did Passive 3D). I mean the panel wasn't true 3D but Software will do it like people did when those 3D TVs were expensive.
I can feel you, when I was in school it was the same but we didn't get to the touchscreen era by that point yet until I graduated, but the carts with a tiny CRT did get replaced by a Sony LCD in each classroom. Once they wondered why sound wasn't coming out of the TV and who do you think had to go there to check?... Anyway the reason for it was... they had stuffed a 3.5 mm jack into the analog sound input RCA jack's hole. No kidding. When I told about it the "technician" there just... stuffed it in deeper, enough to hit the contact it seems and grounded through the VGA I bet, so it sorta worked. Seen janky stuff, but that beat 'em all.
IPTV is practically cable TV over ethernet/IP . Our cable provider decided to sunset their cable network, and swapped out the setop boxen for IP set top boxen that run over a seperate vlan on their network.
best method is still RTMP, you just "subscribe" to a unicast stream at an (Layer2-) switch in your network, which has all the channels, and at that point you are listening on a unicast address with an mpeg stream (of whatever variety your cable operator provides). that's ideal if you have multple TVs in the same Network, assumingly some watching the same channel. Off course there are all those nasty HLS-embedded-opera-webplayers too. they work on L3/L4 (IP routed networks) too, but do off course consume more bandwidth and resources.
It’s used in Europe a lot to illegally stream sports and other TV channels, sports like Football are pretty expensive to watch per month and are spread across providers so it’s a dodgy way to watch the games for cheap
It's a pretty safe bet that no other online video source is covering this exact data in the same way. It's valuable tech info that risks being lost forever. I hope someone out there is archiving these.
TH-cam will probably hit him with a copyright claim or some other TOS issue and remove it. People think stuff on the Internet is forever, the opposite is true, stuff posted to the internet is almost certainly going to be memory holed, forever lost, most of it has been already. What will remain will all be behind paywalls, filtered, moderated, and censored of supposed mis/disinformation you aren't allowed to think. Even the Internet Archives and the WayBack Machine are under attack, they say they've not lost any data but searches I've done show otherwise. And because people think its forever, they don't keep copies anywhere else. I hope a bunch of people are archiving lot's of things, we can't have all knowledge controlled by three or four biased and for-profit companies.
58:16 Annecdotal evidence is annecdotal, but my school district when i was a kid spent a lot of money on SMART's line of digital whiteboards and the teachers who had them loved them. It made going from whiteboard mode to having the NBA playoffs or March Madness pulled up super easy since you didn't have to fight with other Gonzaga obsessed teachers over TV carts or worry about kids breaking projector screens. I remember one of my teachers specifically used it to digitally mark a PDF version of our workbooks so we could all work along with her.
i can also second this, my teachers used them alot with their pcs in highschool, they would just pull up shit that would get projected onto the board and then they would draw all over the board, scroll through slides, do presentations and demonstrations, pretty much anything that could be done on a secondary monitor that you would want to annotate over. i did have some teachers, usually elderly ones, not use them although they were installed in the class anyways
I had some classes with an early Smartboard and it made some lessons much more engaging. My math teacher for example used a lot of silly digital stickers for various things when making or explaining problems for us. Good times.
The dedicated "on" and "off" buttons on the remote also lets you easily automate turning the TV on and off with a 3rd party IR blaster. The IR blaster wouldn't have to guess if the TV is already on when typically a power toggle button was pressed.
Pretty much every TV in existence (as well as many other devuces) will respond to discrete power on and power off signals; it's just unfortunate that virtually no TV remote control includes them. Many universal remote controls will allow you to set up macros that use these discrete power controls to power up multiple devices in a home theater setup simultaneously.
From experience I can tell you that the discrete buttons are super helpful when you have a whole wall of TVs to turn on or off. Without it if you don't hit all the TVs at once with the remote you have to go right up to the TVs that didn't turn on and hope you dont hit the ones that are already on and turn them back off

24:14 there's a rly fun word for this: *idempotency*, which describes commands that have the same effect whether they're received once or multiple times. i learned the word from software development (you can imagine how useful it is to have this idea codified into a little term, when designing protocols to reliably transfer state over an unreliable network) but it's such a useful term for zeroing in on the specific cause of a lot of day to day annoyances. if it hasn't already, i feel like that's a word that should escape its original computer science context and be taught in fields like industrial design, mechanical engineering, etc. Then again, it's a word i wish more software developers knew and thought about, so i might be getting ahead of myself
Interesting example of an idempotent interface: in the Matrix messaging protocol, when you (as a client) want to send a message, you don't just fire off a POST request with your message contents. You send a PUT request with a unique ID (entirely arbitrary, of your choice) in it, and the server guarantees that any message sent multiple times with the same ID will not get sent multiple times. This allows clients to retry sending whenever they want without fear of double-sending a message
I also have 2 NEC panels that I use at home regularly - C751Q that I saved from the dumpster. Professional AV engineer here. Loving watching a different perspective on something as "common" (to me) as a commercial display.
One thing that irks me about modern TVs is that they don't pass DDC/CI into my computer, meaning I can't change the brightness or contrast or turn them off from my computer. I have VGA monitors from the late 2k's that just work like this, and samsung has made displays that can ONLY be controlled via DDC/CI. I use a program called Twinkle tray on windows to control all my displays' brightnesses all at once, and I'm curious if it would support something like that. I could only assume that it does but can't be too certain.
4:38 I work in a television studio environment and we have studio feeds in every room. I'm talking hundreds and hundreds of TVs that are left on 24/7. When we renovated in 2017, we specifically chose a commercial display designed to be on all the time to avoid burn in. We might have color bars on these screens for days at a time when the studio is not in use. Literally all of them had horrible burn in within 3 years.
I was thinking the same, rarely ever seen anything bigger than single or dual 4gig sticks in ddr3.

50:50 It's even more funny, SHA1 hash flowed by '-dirty' was a string generated by git, in which case it was compiled with uncommitted changes in the codebase.
Imagine fixing a bug so in the hurry you didn't even commit changes to the repo, made a crude build locally, sending it to someone and they say "thx, it works now" and then it is the one that gets officially shipped... either this, or they suck at git, or they just don't care
having a tv with a builtin hd-sdi is honestly so useful in broadcast settings, when i worked in a news station we ran all the tvs (20+) in the studio with sdi cables and being able to just plug sdi in without worrying about converter boxes would have been such a clean solution.
Love how it gradually turned from a review of a NEC momitor into a little guys/OPS episode into messing with my ridiculously rage touchscreen using a OPS😄 Love all of this ❤
haha, i thought about cutting it down somehow but I figured everything made logical sense this way. can't talk about the tv without mentioning the slot, can't just handwave the slot, can't only tell half the story of the slot... so let's just do the whole thing!
@@CathodeRayDude Eat up Martha Seriously though, the 70" 4k display looks like it'll also take the bigger "OPS+" module because the back is open, or do the guiderails get in the way?
I feel like all Smart TVs should have this. The thing I don't like about Smart TVs is that eventually the software becomes unsupported and unusable, and then you have to buy an external box and just pretend that the smart features don't exist. Would be so nice if you could just swap a module.
Most "Smart" TVs have such terribly inefficient software and such underpowered CPUs that you are literally better off getting a Roku or Firestick from day 1. Samsung, LG, and Vizio all outright suck from my experience and they're usually missing at least one or two of the major apps out there that require getting something else anyway.
@@alanstrickland9717 I have a Toshiba that runs the FireTV firmware instead of some special crap. I hope this one will hold out a bit longer than the firmwares of other smart TVs.
About the Promethean casting software: I've actually had the opportunity to mess with one in a school setting, and (at least for the one I used, which seems to be a newer model than yours) it just used regular old Miracast. Stock Windows through the Cast menu connected to it perfectly fine, as well as my Android phone. The one I used also had the ability to have multiple (up to 30, maybe 40) devices casting to it... *at once*. I was told that it was able to allow all the students' tablets (unfortunately we're now apparently giving young children iPads in their classrooms) to cast to the screen at once. You could click one of the devices being casted to focus that one full-screen, then click anywhere to go back to split-screen view. The teachers did also have software on their computers that directly connected to it, so they may also have a proprietary protocol, but I know for a fact regular Miracast does work with it. I think that software was actually just a Chrome extension, come to think of it... I'll have to ask around. The metal bar is exactly what you think, to store the pens it comes with. Fun fact: the board can actually tell whether you're using the tip or back of the (official Promethean) pens somehow... as well as detecting when you're using the eraser instead of a pen (it came with an eraser that sticks to the side of the frame with magnets to hold it when you aren't using it)
For most IR-based IFPs like this promethean, it can detect different size objects. I worked for a competitor and the three main sizes it could detect were a thin tip (pen/stylus), thick tip (eraser end), and a larger object like the side of a fist.
@mariol90 I'm sure that's exactly how it works, as regular whiteboard markers and erasers also worked perfectly fine and it detected the difference properly.
The one thing that was missing was probably having something else on screen, like the downtime screen used in the streams in the middle so the scrolling patrons on the TV (which was _brilliant)_ don't look so lonely.

Your explanation of solutions to problems that no one else thinks about is more satisfying than I could have imagined. I wish more consumer technology was designed with a finite state machine philosophy.
IPTV isn't just a Europe thing, Rogers' TV in Canada, AT&T's U-Verse and Google Fiber's TV offering is also an IPTV system (the former two based on Microsoft's "MediaRoom" IPTV platform, but all three using Multicast UDP streams to deliver video, audio and the interface). But in Europe they have regulations defining the standard and allowing people to bring their own receivers. In NA, they use proprietary encryption systems to lock you into using their set-top boxes (or if you can get a supported option, the "CableCard" standard) to control what you can receive.
I went to school in an era of transition between blackboards and whiteboards and later returned during the SMART board era. Back in the day teachers would write on the board and when it was full they'd give us time to make notes then wipe the board and carry on. With SMART boards the teacher would just save the screen then move on and share each board with the class at the end of the lesson negating the need to take so many notes.
I was at uni during the transition. Some of the old school lecturers still insisted on writing on the board and talking at you and you just had to write down as much as possible. If you didnt, you literally didnt have the material that would be on the exam. The younger ones had powerpoints and used to upload them to the student portal at the end of the day and us students just downloded them. Ironically, those with powerpoint slides ended up with theatres full of half asleep people - they didnt need to listen, they just downloaded the slides later anyway - and you can bet most of them went unread, or at least undigested/unexplained for most. When some of the powerpoint crew noticed the grades for their classes were plummeting, they started leaving "traps" - deleting paragraphs, missing points etc in the slides they uploaded. I did a bio degree, and one of our lecturers had slides, but the slides were literally useless - about four pictures of cows, he'd do all the talking and there was almost zero content on the slides themselves - you HAD to take notes - but you didnt becuase slides....you only fucked up one semester as you learned the notes werent all hand fed any more. Im still not convinced death by powerpoint is a good way of teaching....
13:00 NTSC 4:43 is NTSC for 50Hz and colorburst at 4,43Mhz. Is a NTSC for European tv standard's. PAL-60 Is the other way around. PAL on 60Hz, or PAL for 60Hz, but with colorburst at 4,43Mhz. SECAM was the French color TV system. There's also PAL-M used Brazil. Mutch like PAL-60, but with colorburst at 3,56Mhz, to viabilizar broadcast PAL tv signal at 60hz on top of "NTSC" transmitters. The weirdest one is PAL-N. Is PAL at 50hz, just like European PAL, but with colorburst at 3,58Mhz to be able to broadcast on "NTSC" transmitters. Was used on Argentina, Paraguay and Uruguai
NTSC 4.43 is for playing back NTSC VHS tapes on multi standard VHS recorders intended for the European market. VHS recorders (probably all the other video recorders too) frequency shifts the color sub carrier. By playing back both PAL and NTSC at 4.43MHz the recorder only needs to be able to play back the color signal at 4.43, saving some parts. Those multi system recorders were packed full of circuits back in the days where all signal processing was analogue. PAL 60 is supported by all DVD players sold in Europe. The purpose is to play NTSC DVD:s on a TV that only has a PAL color decoder. Since perhaps mid 1980's or so the vertical sync circuit of all TVs started using ICs that automatically sync to either 50 or 60 Hz and in most cases automatically have the correct vertical size too. Multi color systems though cost actual components, band pass and band stop filters, crystal oscillators and whatnot, and it was also possible to charge a premium for a multi system TV, so most TVs could only decode PAL (and SECAM if they were sold in West Germany, because everyone watched East German TV but no one officially admitted to doing that, it seems). PAL 60 would also be useful for example if you switch to 60Hz/"NTSC" on an Amiga but still have the PAL color encoding / RF modulator things and use a TV or composite monitor as a display. I honestly don't know who had any use for PAL-60 on DVD players. I think it was just included to lessen complaints from consumers who didn't know how to connect things correctly, as all but the cheapest budget TVs had RGB inputs in Europe since the mid 1980's.
@@RetroSwim Yes, I think that the in the last part of the life of VHS some recorders were able to play back NTSC in the PAL world and then transcode the NTSC color signal to PAL, thus generating PAL-60. But the common use cases are those I stated in another comment in this sub thread Side track: i don't think that there were ever TVs sold in Europe that could display NTSC 4.43 but not NTSC 3.58, even thought that would technically had made sense since it would had been super cheap to add to certain TVs (just a few diodes for the switching logic, kind of). I think this never happened due to it being a marketing night mare as it would require explaining too much to ensure consumers wouldn't get angry about it not displaying NTSC 3.58. Another side track: I've never heard about people (rightfully) complaining about their European multi standard VHS recorders not working with North American TVs.
@Thesecret101-te1lm well, not quite. Let me explain. There's quite a difference between what the NTSC is for Americans and what it is for the rest of the world. For Americans, NTSC is the television system as a whole. It doesn't matter if it is color, black and white. If it works at 60hz, it is NTSC, and if not, it is PAL, but it is not even close to that simple.
In the rest of the world, mainly in Europe, every country has its own television system that is different from each other for many reasons. For example, during the Cold War, you had East and West Germany, each running their own television system. Why? In that way, western Berlin audiences were not able to watch content broadcasted in the East and vice versa. A mess. With that in mind, during the 60s', a French commission named CCIR cataloged every TV system in the world and put a letter on it. With the arrival of color, there was a mix and mesh between systems, and so then, side to the letter, there's the color TV system, and that is the NTSC for the rest of the world.
When I saw that POP feature, I immediately recognized it. I've seen something similar in a medical waiting room where the largest image displayed a TV signal, the smallest image showed something like a feed of weather and the time, and the "sidebar" showed information related to the office, like wait times for each doctor, etc. I'm not sure if this exact display could do something like that, but I bet it could.
What killed my opinion of Smart TVs as a concept was a truly horrible Vizio. You had to be careful when you changed the volume because that was such a taxing activity for the SOC. You could easily crash it by streaming Max and changing the volume.
When using the "free" command in linux, the "available" column is actually the one that's relevant. The "free" column basically says "how much memory hasn't been touched by the OS", but there can be plenty of memory that has been *marked* to be freed by applications, hasn't been truly deleted yet. The "available" column counts all of the memory that *can* be allocated.
@@CathodeRayDude FWIW even in the "professional" software engineering industry, it seems like most people don't realize it. I had to explain that to a coworker (whom I consider very smart) about a year ago, so you're in good company. Also, something I do if I have to run a linux where the repos are all dead, is to quickly install the alternative package manager "Nix". It runs on pretty much any Linux and macOS and has most of the packages, and is pretty up to date. I find it generally more reliable than depending on old Fedora mirrors.
I had to explain to a sysadmin just this year about how Linux will use free memory for cache and that you have to take that into account when looking at the memory usage stats.
NTSC 4.43 is for PAL VCRs playing NTSC tapes, while still using the PAL colour oscillator already in the VCR. PAL60 is for using 60hz video signals on PAL TVs that can accept a 60hz refresh rate but not NTSC colour, mainly useful for older video game consoles. PAL60 should also not be confused with PAL-M, which uses (almost) the NTSC oscillator frequency, and was used in Brazil.
We have these Prometheans (not the exact model slightly newer) in schools in germany. I work as a School Admin and know these very well. The newer ones allows iPads to connect wirelessly, so students can share their work, the teacher can then at any moment freeze the screen and draw over it to correct or further explain things. Really nice actually. Though we shifted on using Smartboards as the UI is much nicer and they are almost 1000 Euros cheaper. Smartboards have a built in OPS module not that easily accessible, but it still can be swapped or bought with an x86_64 module. All of those, even the new ones still have front io for teachers to plug in their own devices via hdmi, the newest even have thunderbolt 3 inputs on the front and back. We are going to swap all ops modules with windows 11 compatible ones this year. I love that we can fit 10 year old devices with modern hardware capable of running Windows 11 at nearly a 5th of the price of buying new ones. For schools with limited funds this is insanely valuable!
6:00 IPTV is used a lot in hotels (my industry) to deliver TV service to guest rooms, we call it free-to-guest. Gym equipment with built in displays often have that signal delivered via IPTV as well. You're right, it's just TV delivered via a CAT5/6 cable
My high school had smart boards and yeah, teachers really didn't like them. They only ever used them as standard projectors for slideshows and just viewed them as permanently occupying whiteboard space and universally preferred the traditional pull-down whiteboard screens that could then be raised back up if they needed the whiteboards. Although in my college classes, one of my professors brings in a drawing tablet and uses that on the projector for everything, so he can save the notes and then share them after class so I guess that's the converse if there aren't smart whiteboards lol
A handheld Wacom tablet is worlds better than having to raise your arm up to a smart whiteboard with high latency, honestly. I bet more profs would share a copy of their notes if they were given a tablet rather than a smartboard.
This video is my main piece of evidence that there's something extremely cathartic about slotting in a cartridge and pop culture lost something once we moved on from VCR's and Game Carts.

2:14 What's funny is that channels normally broadcasting interlaced signals would switch to progressive when showing movies! (at least that's what I discovered when recording DVB signals in Britain in 2006)
Yep, the DVB standard allows for switches from 50i to 25p, this can even be used within individual TV shows. A great example is Top Gear on the BBC which used 50i for it's studio segments and switched to 25p for any pre-recorded VTs.
I have always bought NEC displays as TV's. I use a 40" outside that has survived several hurricanes and a 98" in my family room that has been nothing but a pleasure. Accessing your TV settings through a web browser is just the way.
It is actually quite common for the tuner in consumer-grade TVs to be a plug-in module as well, so they can sell the same TV around the world and only install different tuners as necessary for each region. It just isn't meant for the consumer to easily swap out. And there are usually settings which can influence the type of de-interlacing used, such as "Game Mode" which sacrifices quality to reduce input lag, or that awful "TruMotion"-type feature which tries to interpolate everything to 60fps or even 120fps.
The digital white board I have at my office not only has HDMI IN on the front panel, but also a full fat USB-C port I'm too lazy to check is thunderbolt, but certainly feels that way. Not only does it do 4K60, but it also passes through any USB devices plugged into the whiteboard (although regrettably not the ones on connected OPS modules, that would have been insane), passes audio to the speakers and the microphones, and enumerates its display as a touch surface AND a wacom display, while delivering 96W of PD. It's insane, and I love it.
Probably been answered already, but as an Aussie who was gaming as a kid in the late 90's and early '00s, PAL60 was a godsend. PAL only refreshed at 50hz,rather than NTSC's 60. PAL60 was supported by many Dreamcast, PS2, OG Xbox and GameCube games to allow them to run at 60FPS on Aussie TVs. Finally, we could play F-Zero GX at the blistering speed it was meant to be played!
I think that second grid you pulled up at 57:40 is for writing Japanese [and presumably other east asian], that's why it has square cells horizontally, one [well, a 2x2 mini-grid] per character.
It's just a grid pattern, when I was a kid all of our math books looked like that, that way you could lay out sums and ensure it all lines up for showing your workings.
FYI: idk if someone already mentioned this, but I am in a district that is all promethean boards (more modern than yours), and the built in screen sharing feature, at least on the modern ones, does support window's built in screen mirroring feature, though not super duper well. For example, if you set the screen mode to extend, the display will only render the pc's extended screen in 4:3 for some strange reason. The neat part about the promethean side though is the ability to have a waiting room where like a class can have all the people presenting connect before hand, and you can live swap who's input is being displayed.The neat thing about the modern promethean OPS modules (and I feel like yours does it too from a side channel video you did a while ago? I could be wrong) is that they completely replace the built in OSD, and also have multiple overlay features on the HDMI inputs, such as a large timer, and an on screen annotation tool, that doesn't require the pc to ever receive the touch input. Our district probably found out when setting these things up initially that the official promethean screen share software is so annoying to use, that they specifically bought these devices that just get mounted onto the back of the board called ScreenBeams, which would handle the usb touch input coming from the USB B cable on the back of the display, and ofc the sending of the connected computer's image to the board. The really strange thing is all of the ones in my district (i've checked at multiple schools) actually come with a FRICKING DOS EMULATOR??? called FreeDosBox... I put the oregan trail on one of them using that, and also windows 3.1 which is really really silly to me lol. Also have poked around the OS a lot, it is way more locked down than the one you have, doesn't have the google play store and you can't load apks. If anyone does want to ask me anything more about how our school district is setup with these/how teachers actually use them, feel free to ask.... I ramble a lot as you can tell lol.
Looking at one again today, I am unsure if there even is an OPS module installed in it, there is a slot, but it looks like it may just be a cover, with a built in grabbing handle. It could be a card, but it has no IO, and the Wi-Fi antennas aren’t located on OPS slot. Instead, they’re on another module in a tiny slot (no idea what standard that is/could be, if it even is a standard) underneath the OPS slot. Heck, it may not even be an OPS slot, it might be the new intel one that was mentioned at the end of the video, tho the slot size does match up with OPS so idk. I don’t know if I’d ever even get the chance to remove the slot to see if their is an actual module or not, since I don’t want to get in trouble for “property damage” or “hacking”.
Hey, just wanted to thank you for your videos and all the crazy cool stuff you bring to the table .... I love the long content and I think the best ones are the videos I look at and go, "WTF?", this outta be interesting and they are always a treat! Have a wonderful day! 😊🌎♥️🕺🐕📺
You know, for years I've been saying PC AIOs should work just like an OPS module (though I didn't know of their existence). Let you upgrade years down the line, or if the screen is still good you could just get a module with whatever kind of inputs you want.
CEC is a serial communication that allows TVs and devices to talk to each other 2-way to do things like change volume inputs, and synchronize power statuses.
PAL60 ended up being quite common in Europe - it's just PAL but at 60Hz, so if the game you were playing on a game console supported PAL60, you'd get both the resolution of PAL and the refresh rate of NTSC(-ish). I know the Playstation 2 supported it, but it was up to individual games to support it.
If you're European and played on PS2 or Dreamcast (probably the other consoles as well), you probably saw games asking you on startup whether to use 50 or 60 Hz. Usually also including a test mode so you could check what your TV supports.
Thank you for helping me not think about reality for an hour and fifteen minutes. I’ve read so many books and played so many video games these past two days so as not to fall into the blackest despair
I installed so many of these in different sizes and layouts. PCs of the time couldn't support more than 2 HD screens, so the tiling feature was great for bigger arrays. They had a ton of hours on them by the time they got decommissioned, so buying a used one is a gamble!
Adding a word of thanks for giving us some compelling content on a dark day. It's good to know you're out there being curious and excited about offbeat devices.
Our high school started installing paramedian boards right at the tail end of me being there (2008-2009) and they were neat. Basically gigantic drawing tablets with a projector projecting on to them. They did not have touch support and you had to use a pen but they were surprisingly responsive for the time and teachers could email you the notes.
PAL-60 was used in Brazil. Aka PAL-M: exactly the same B&W M standard from the US (bandwidth, channel frequencies) but using PAL color standard adapted M system.
@@LordVarkson proper pal-m has different amount of lines(like ntsc, 525) Pal-60 is the pal(50) just at 60hz(625 interlaced lines). Or its pal-m. Depends on the device. Only universal tv cards and such tend to support both even if the chips in the devices would.
in elementary school i remember that it was always a struggle for the teachers to get the one SMART board that the entire grade was supposed to share. by high school even the oldest construction had SMART boards mounted on the walls. i definitely don't follow the "these things just sit around collecting dust" story, most of my classes were powerpoints that the teachers would mark up while talking. the one time i had a math teacher that actually used a chalkboard it was a genuine novelty
At 12:16 about different color systems, back in 1996 I worked for Samsung and helped design a video decoder chip that could do the usual NTSC PAL SECAM standards and those extra oddball systems as well.
Ok, ok please tell me what the hell PAL60 actually is, cause I've never figured it out. Some people say it's the PAL video format running at 60hz, some say it's NTSC with PAL colour while others have said it's literally just NTSC and they're lying to you.
Wired remote is mostly useful in situations where you have multiple of these facing the same direction but you do not want the remote to control all of them at once. Also you do HAVE to daisy chain dvi for video walls on these. If you run the same video signal with separate cables tiny delays can happen among different displays and it can result in visual tearing especially if the image has fast moving things in it (sports)
There's just something incredibly satisfying about digital whiteboards. I remember in the very early 2000s we had one in our boardroom that worked with a projector and the screen was the size of the whole wall. Drawing on itt seemed like magic to me, although I suspect if I saw it again now it would look very clunky.
We had smart boards at my high school, and the few teachers that used them as a way to provide a copy of the whiteboard online after class and nothing else. Interestingly they used an existing projector as a display.
US doesn't have IPTV to the point you never heard about it?! US is build around coaxial I guess, on top of which the internet was added later as an additional frequency. EU has newer infra, which was internet-first, and TV is added as a service over network (Ethernet or optical), it's just a UDP multicast in many cases, sometimes just MPEG-TS over HTTP.
Also a lot of the US infrastructure is older and saturated, so running TV over coaxial in dedicated frequencies instead of running them all through cable internet makes sense. Although fiber is becoming more common
My school uses these. If you want, i can tell you that there is newer versions of these with at most Android 9 or 10 on them. Also, glad you are covering these! My percussion teacher loaded his with subway surfers, and musical tiles.
i had a thing for these types of commercial screens, i always wanted one of these with touch screen and a built in pc. I now have 2x 2021 55inch 4k 20point touchscreens from liyama that can house a computer and has android running in the background. That 75inch is a beast!! awesome video! 😉
23:30 IIRC The game "Dragon's Lair" actually used this feature, basically hijacking the remote capability of its Laserdisc player to skip to specific chapters and frames on the disc
Im the uk those boards are pretty well used, though normally just connected to a PC and then you can write over your slideshow for the lesson, some newer ones don't even rely on PowerPoint/SMARTs proprietry software etc. to handle it right and just overlay the drawing onto the video input if you wants. They also usually come with training for teachers.
Commercial TVs are THE TVs. My daily driver is a 65in Panasonic plasma commercial display from 2006 and it's an absolute champ, any signal adjustment setting you can imagine for any twisted kind of source you plug into it. The speakers on that, on the contrary, are way superb to any TV I've heard in the past two decades too, but they are basically two column speakers that clamp to the sides of the TV :P Oh, and mine didn't come with a tuner module, so I don't have to pay the NHK tax too!
Our teachers mainly used these just like those overhead projector screens, just mirroring the computer. History teacher actually used the whiteboard feature to write notes that we had to copy. Classrooms with overhead projectors had ActiveInspire installed on the pc

In the age of smart TVs that requires user agreements and have ads injected into the UI, using an NEC digital signage display for my home TV -- no garbage, no frills, virtually indestructible panel -- has been bliss.
At my old workplace, there was a set of NEC MultiSync panels in the lobby, displaying the same static map and welcome message, 24/7/365, for as long as anybody could remember.
I checked their uptimes one day and found they were both identical: 32,767 hours. They hit the integer limit years ago and just stopped counting. Still looked and functioned like new.
That's one reason I use my PC as a media center and a wireless mouse as my remote control.
We just had a meeting with LG and #1 and #2 on our list of features was “No special software or OS” and “No EULA”.
Why my 4k uhd roku hisense has no internet connection
digital sinage displays have got to be the best discovery i've made when looking for "modern dumb TVs", got myself a 70" version of the NEC for an equivelant of 300USD and using the PIP mode to watch some shows while playing on my xbox has been really fun
Or you could just not connect it to the internet? Why would you go out of your way to get a signage display with atrocious image quality?
DUDE.
OK so hear me out, I promise this is going somewhere.
Years ago one of our clients spent a HUGE amount of money on a ~80 inch smartboard TV for their conference room that used an OPS Module.
When we ordered it and the module, they sent the wrong module and when we called them they shipped the correct one.
They told us to keep it. I'll never understand why.
I tried to sell it on eBay for quite some time but got no takers. I'm pretty sure it's this same connector/standard but have to go look tomorrow.
I think we still have it, and my boss would almost certainly let me send it to you.
OKOKOK here's the thing about it.
This particular module is not a "little guy" in the way you think.
This particular module uses AN INTEL COMPUTE CARD, and HAS ONE IN THE BOX with it.
For once I'm excited to check the shelves at work. Will report back to these comments if I'm right about it being a normal OPS module.

My wife is a high school math teacher, she and her colleagues use their smart whiteboards daily.
The really seems to be a sharp divide, half of people say these things never get used, the other half said they couldn't live without them. I'm glad to hear that a lot of them are getting used!
@ not being a teacher I just assume they are good for math and garbage die anything else. Even when I was in school the projectors only got used by math teachers.
@@CathodeRayDude Teachers are sometimes extremely set in their ways. They also will hold on to tech from decades ago, because it still works even when a better solution presents itself. As I said in my earlier post the best way to get them to use this stuff is to not give them another option. Rip out(or in most cases since it's cheaper just mount this on top of it) their traditional white board and they will have no other option. As someone who has worked in and around education for over a decade its frustrating to deal with someone who couldn't program the clock on their VCR bitd, but is also responsible for educating young minds. Technology literacy is just as important as actual literacy yet there are still teachers you have to drag kicking and screaming out of the 90s.
@@CathodeRayDude This seems pretty much true to my experience. I was at the end of primary school during the first wave of digital whiteboards starting to take off (around 2004-06, when they were replacing OHPs with PC projectors instead, and thus the terrible calibration experience of syncing up some kind of touch/pen-sensitive canvas with a projector that try as you might you can never quite keystone correctly), and there always seemed to be a roughly 50/50 divide between the teachers who used their digital whiteboards AS digital whiteboards, and those who only used them as they would do a PC projector with no whiteboard functionality, i.e. effectively as a more complicated OHP.
In my secondary school, we didn't have many digital whiteboards, (though there definitely were SOME). most classrooms just had PC projectors and pull-down screens (or just projected ONTO a standard whiteboard, so would often annotate the display directly using dry-wipe), though some classrooms also had document cameras hooked up to their projector to TRULY recreate the OHP experience.
@CathodeRayDude some are also SMART Technologies SMART boards, a projector with a laser that tracks if something crosses the display
It's basically projector + crappy "touch screen" bolted to computer = crappo
A modern TV without built in Chromecasts, tracking and invasive advertising is a dream come true. Which was also a reality less than 5 years ago.
Just don't connect it to the internet and problem solved
Not really 5 years ago. Back in 2012 my friend at uni had a TV they had bought for uni which had smart apps built in.
I want dumb, chromecast or a decent chip. My Sony has a very fast soc and 4gb ram so runs TH-cam and game streaming from my pc just fine
What're you on about? I bought a TV in 2017, it was a "Smart TV", and you couldn't get non-smart TV's at the time.
@@LetrixAR Louis Rossman had an expensive LG model with premium quality panel, which he, as far as I understood from his rant video, could not fully use without connecting to the internet.

Braaaainz!
What an incredibly violent act. I was shocked!
28:21 Having a screen WITHOUT the tuner allows you to avoid paying TV "tax" in some countries.
Came here to say this. Many countries fund(ed) their public broadcast system via television (and before that radio) fee that was often "per tuner". Thus entities who needed only the display didn't want tuners included.
UK's BBC and Japanese NHK especially! 😅
Gotta have a loicense for that m8

Your line about nerds wanting the best possible commercial grade equipment just to mess around with and do absolutely nothing useful is painfully accurate.
Signed, a person who just spent 6 months learning to repair IBM Selectric typewriters, got one fully restored after countless painful setbacks, and now uses it to do occasional journaling and type about... my sweet working IBM Selectric typewriter.
"This sure is better than a word processor. No distractions here! It only takes a bachelor's degree worth of knowledge to keep it working, so much fun!"
This man really just listed every reason why you'd need an always on commercial display.
I don't remember it being specifically called out, but obviously inferred, the fact that the screen could run for a decade or two at a shot in continuously on state, w/o losing it's backlight at 2 years, kind of sold me on the idea. I'll be watching for some on e-bay when the latest batch of 32" TV's die in a year or two. Did a search this morning, and found half a dozen e328 models ranging from $129 to $299 available as buy it now or best offer. No available funds at the moment, so holding off on those. Pretty sure that more will show up.
@@RNMSC We got a Samsung Digital Signage display for a project at work, the thing is rated for 24/7 operation for like 50000 hours MTBF. Literally over 5 years of continuous nonstop usage.
Pro gear is on another level altogether. Then again you feel it with a tap on the panel. A normal household LCD feels like it will shatter with a tap (and will with a slightly harder hit), that thing feels like it's twice as thick at least. It just doesn't flex the glass. And it's just a plastic frame one, none of that super rugged extra heavy steel casing stuff like the NEC Gravis showed here.
my high school started installing the newest version of those things during my senior year. they had an account system for like multiple teachers and everything. and I was the person who got told by the teachers to fix the things when the inputs eventually came unplugged. I have also plugged multiple ancient dvd drives into them because I was the techy kid. they used basically none of the inbuilt features outside of the screencast and basically used them as overhead projector replacements. gotta love how state money went to buying them instead of fixing the mold problem in my rundown rural high school from the 70's.
Yeah that sucks but budgets are allocated by category so the tech budget was probably eight times more than the mold remediation budget! 👍🏽😬
So, your School couldn't have bought Polyboard or Promethean or Smart or LG Pentouch or the Microsoft Whiteboard or Google Jam Board or the Samsung (whatever they call them now) or Vibe board or Viewsonic or Benq boards.
My School as did the same thing with the Promethean Activ Titaniums. At least they bought the lower storage ones that were 64 GBs and not expansion cards running ChromeOS or Windows 10/11 IOT they were all 65 inch versions from my memory. They never used all the features, just Teams installed from the Google Play Store. And my School had HP USFFs tons of them they never used them and I connected them for them. So, glad USB Plug and Play exists I was not going to fight with User Account Control. They also had Surfaces Brand new Never Used and a whole lot more. But, I gotta admit you could easily get into the "secret service settings" The display's mainboard UI and enable 3D since they also have 3D Glasses from the Smart Projectors (Our Old ones did Passive 3D). I mean the panel wasn't true 3D but Software will do it like people did when those 3D TVs were expensive.
I can feel you, when I was in school it was the same but we didn't get to the touchscreen era by that point yet until I graduated, but the carts with a tiny CRT did get replaced by a Sony LCD in each classroom.
Once they wondered why sound wasn't coming out of the TV and who do you think had to go there to check?... Anyway the reason for it was... they had stuffed a 3.5 mm jack into the analog sound input RCA jack's hole. No kidding. When I told about it the "technician" there just... stuffed it in deeper, enough to hit the contact it seems and grounded through the VGA I bet, so it sorta worked.
Seen janky stuff, but that beat 'em all.
So you learned about corruption at an early age....🤣
IPTV is practically cable TV over ethernet/IP . Our cable provider decided to sunset their cable network, and swapped out the setop boxen for IP set top boxen that run over a seperate vlan on their network.
It’s not terribly standardized, though.
Unsubsidized instantly
Thank you for reminding me of that old Brian Regan skit with "boxen".
best method is still RTMP, you just "subscribe" to a unicast stream at an (Layer2-) switch in your network, which has all the channels, and at that point you are listening on a unicast address with an mpeg stream (of whatever variety your cable operator provides). that's ideal if you have multple TVs in the same Network, assumingly some watching the same channel.
Off course there are all those nasty HLS-embedded-opera-webplayers too. they work on L3/L4 (IP routed networks) too, but do off course consume more bandwidth and resources.
It’s used in Europe a lot to illegally stream sports and other TV channels, sports like Football are pretty expensive to watch per month and are spread across providers so it’s a dodgy way to watch the games for cheap

58:16 Annecdotal evidence is annecdotal, but my school district when i was a kid spent a lot of money on SMART's line of digital whiteboards and the teachers who had them loved them. It made going from whiteboard mode to having the NBA playoffs or March Madness pulled up super easy since you didn't have to fight with other Gonzaga obsessed teachers over TV carts or worry about kids breaking projector screens. I remember one of my teachers specifically used it to digitally mark a PDF version of our workbooks so we could all work along with her.
i can also second this, my teachers used them alot with their pcs in highschool, they would just pull up shit that would get projected onto the board and then they would draw all over the board, scroll through slides, do presentations and demonstrations, pretty much anything that could be done on a secondary monitor that you would want to annotate over. i did have some teachers, usually elderly ones, not use them although they were installed in the class anyways
Teachers that knew how to use them were amazing, teachers who didn't were reality.
I had some classes with an early Smartboard and it made some lessons much more engaging. My math teacher for example used a lot of silly digital stickers for various things when making or explaining problems for us. Good times.

The dedicated "on" and "off" buttons on the remote also lets you easily automate turning the TV on and off with a 3rd party IR blaster. The IR blaster wouldn't have to guess if the TV is already on when typically a power toggle button was pressed.
Pretty much every TV in existence (as well as many other devuces) will respond to discrete power on and power off signals; it's just unfortunate that virtually no TV remote control includes them. Many universal remote controls will allow you to set up macros that use these discrete power controls to power up multiple devices in a home theater setup simultaneously.
From experience I can tell you that the discrete buttons are super helpful when you have a whole wall of TVs to turn on or off.
Without it if you don't hit all the TVs at once with the remote you have to go right up to the TVs that didn't turn on and hope you dont hit the ones that are already on and turn them back off

24:14 there's a rly fun word for this: *idempotency*, which describes commands that have the same effect whether they're received once or multiple times. i learned the word from software development (you can imagine how useful it is to have this idea codified into a little term, when designing protocols to reliably transfer state over an unreliable network) but it's such a useful term for zeroing in on the specific cause of a lot of day to day annoyances. if it hasn't already, i feel like that's a word that should escape its original computer science context and be taught in fields like industrial design, mechanical engineering, etc. Then again, it's a word i wish more software developers knew and thought about, so i might be getting ahead of myself
oh hell yeah THAT'S what that means! i never knew
Interesting example of an idempotent interface: in the Matrix messaging protocol, when you (as a client) want to send a message, you don't just fire off a POST request with your message contents. You send a PUT request with a unique ID (entirely arbitrary, of your choice) in it, and the server guarantees that any message sent multiple times with the same ID will not get sent multiple times. This allows clients to retry sending whenever they want without fear of double-sending a message

One thing that irks me about modern TVs is that they don't pass DDC/CI into my computer, meaning I can't change the brightness or contrast or turn them off from my computer. I have VGA monitors from the late 2k's that just work like this, and samsung has made displays that can ONLY be controlled via DDC/CI.

having a tv with a builtin hd-sdi is honestly so useful in broadcast settings, when i worked in a news station we ran all the tvs (20+) in the studio with sdi cables and being able to just plug sdi in without worrying about converter boxes would have been such a clean solution.

I feel like all Smart TVs should have this. The thing I don't like about Smart TVs is that eventually the software becomes unsupported and unusable, and then you have to buy an external box and just pretend that the smart features don't exist. Would be so nice if you could just swap a module.
Most "Smart" TVs have such terribly inefficient software and such underpowered CPUs that you are literally better off getting a Roku or Firestick from day 1. Samsung, LG, and Vizio all outright suck from my experience and they're usually missing at least one or two of the major apps out there that require getting something else anyway.

About the Promethean casting software: I've actually had the opportunity to mess with one in a school setting, and (at least for the one I used, which seems to be a newer model than yours) it just used regular old Miracast. Stock Windows through the Cast menu connected to it perfectly fine, as well as my Android phone. The one I used also had the ability to have multiple (up to 30, maybe 40) devices casting to it... *at once*. I was told that it was able to allow all the students' tablets (unfortunately we're now apparently giving young children iPads in their classrooms) to cast to the screen at once. You could click one of the devices being casted to focus that one full-screen, then click anywhere to go back to split-screen view. The teachers did also have software on their computers that directly connected to it, so they may also have a proprietary protocol, but I know for a fact regular Miracast does work with it. I think that software was actually just a Chrome extension, come to think of it... I'll have to ask around.

Fun fact: the board can actually tell whether you're using the tip or back of the (official Promethean) pens somehow... as well as detecting when you're using the eraser instead of a pen (it came with an eraser that sticks to the side of the frame with magnets to hold it when you aren't using it)
Yes the software is just a regular Chrome extension, just "Promethean Screen Share" in the chrome webstore
For most IR-based IFPs like this promethean, it can detect different size objects. I worked for a competitor and the three main sizes it could detect were a thin tip (pen/stylus), thick tip (eraser end), and a larger object like the side of a fist.
@mariol90 I'm sure that's exactly how it works, as regular whiteboard markers and erasers also worked perfectly fine and it detected the difference properly.
Dude, this new format is awesome! Also, that Patreon segue was smooth as hell... Your showmanship has really improved with the extra space
The one thing that was missing was probably having something else on screen, like the downtime screen used in the streams in the middle so the scrolling patrons on the TV (which was _brilliant)_ don't look so lonely.

IPTV isn't just a Europe thing, Rogers' TV in Canada, AT&T's U-Verse and Google Fiber's TV offering is also an IPTV system (the former two based on Microsoft's "MediaRoom" IPTV platform, but all three using Multicast UDP streams to deliver video, audio and the interface). But in Europe they have regulations defining the standard and allowing people to bring their own receivers. In NA, they use proprietary encryption systems to lock you into using their set-top boxes (or if you can get a supported option, the "CableCard" standard) to control what you can receive.
Some thai providers use some iptv over fiber. You get a tv box with the fiber internet, tv box being a customized android box.
I'm french and my ISP (SFR) has an IPTV and it's some proprietary multicast stuff
I went to school in an era of transition between blackboards and whiteboards and later returned during the SMART board era.
Back in the day teachers would write on the board and when it was full they'd give us time to make notes then wipe the board and carry on. With SMART boards the teacher would just save the screen then move on and share each board with the class at the end of the lesson negating the need to take so many notes.
I was at uni during the transition. Some of the old school lecturers still insisted on writing on the board and talking at you and you just had to write down as much as possible. If you didnt, you literally didnt have the material that would be on the exam. The younger ones had powerpoints and used to upload them to the student portal at the end of the day and us students just downloded them. Ironically, those with powerpoint slides ended up with theatres full of half asleep people - they didnt need to listen, they just downloaded the slides later anyway - and you can bet most of them went unread, or at least undigested/unexplained for most. When some of the powerpoint crew noticed the grades for their classes were plummeting, they started leaving "traps" - deleting paragraphs, missing points etc in the slides they uploaded. I did a bio degree, and one of our lecturers had slides, but the slides were literally useless - about four pictures of cows, he'd do all the talking and there was almost zero content on the slides themselves - you HAD to take notes - but you didnt becuase slides....you only fucked up one semester as you learned the notes werent all hand fed any more.
Im still not convinced death by powerpoint is a good way of teaching....
On SMART notebook right?

NTSC 4:43 is NTSC for 50Hz and colorburst at 4,43Mhz. Is a NTSC for European tv standard's.
PAL-60 Is the other way around. PAL on 60Hz, or PAL for 60Hz, but with colorburst at 4,43Mhz.
SECAM was the French color TV system.
There's also PAL-M used Brazil. Mutch like PAL-60, but with colorburst at 3,56Mhz, to viabilizar broadcast PAL tv signal at 60hz on top of "NTSC" transmitters.
The weirdest one is PAL-N. Is PAL at 50hz, just like European PAL, but with colorburst at 3,58Mhz to be able to broadcast on "NTSC" transmitters. Was used on Argentina, Paraguay and Uruguai
Great explanation. Most common use (speculation) is probs VCRs that let you watch NTSC tapes on PAL TVs and vice-versa.
NTSC 4.43 is for playing back NTSC VHS tapes on multi standard VHS recorders intended for the European market. VHS recorders (probably all the other video recorders too) frequency shifts the color sub carrier. By playing back both PAL and NTSC at 4.43MHz the recorder only needs to be able to play back the color signal at 4.43, saving some parts. Those multi system recorders were packed full of circuits back in the days where all signal processing was analogue.
PAL 60 is supported by all DVD players sold in Europe. The purpose is to play NTSC DVD:s on a TV that only has a PAL color decoder. Since perhaps mid 1980's or so the vertical sync circuit of all TVs started using ICs that automatically sync to either 50 or 60 Hz and in most cases automatically have the correct vertical size too. Multi color systems though cost actual components, band pass and band stop filters, crystal oscillators and whatnot, and it was also possible to charge a premium for a multi system TV, so most TVs could only decode PAL (and SECAM if they were sold in West Germany, because everyone watched East German TV but no one officially admitted to doing that, it seems).
PAL 60 would also be useful for example if you switch to 60Hz/"NTSC" on an Amiga but still have the PAL color encoding / RF modulator things and use a TV or composite monitor as a display.
I honestly don't know who had any use for PAL-60 on DVD players. I think it was just included to lessen complaints from consumers who didn't know how to connect things correctly, as all but the cheapest budget TVs had RGB inputs in Europe since the mid 1980's.
@@RetroSwim Yes, I think that the in the last part of the life of VHS some recorders were able to play back NTSC in the PAL world and then transcode the NTSC color signal to PAL, thus generating PAL-60.
But the common use cases are those I stated in another comment in this sub thread
Side track: i don't think that there were ever TVs sold in Europe that could display NTSC 4.43 but not NTSC 3.58, even thought that would technically had made sense since it would had been super cheap to add to certain TVs (just a few diodes for the switching logic, kind of). I think this never happened due to it being a marketing night mare as it would require explaining too much to ensure consumers wouldn't get angry about it not displaying NTSC 3.58.
Another side track: I've never heard about people (rightfully) complaining about their European multi standard VHS recorders not working with North American TVs.
@Thesecret101-te1lm well, not quite. Let me explain. There's quite a difference between what the NTSC is for Americans and what it is for the rest of the world. For Americans, NTSC is the television system as a whole. It doesn't matter if it is color, black and white. If it works at 60hz, it is NTSC, and if not, it is PAL, but it is not even close to that simple.
In the rest of the world, mainly in Europe, every country has its own television system that is different from each other for many reasons. For example, during the Cold War, you had East and West Germany, each running their own television system. Why? In that way, western Berlin audiences were not able to watch content broadcasted in the East and vice versa. A mess.
With that in mind, during the 60s', a French commission named CCIR cataloged every TV system in the world and put a letter on it. With the arrival of color, there was a mix and mesh between systems, and so then, side to the letter, there's the color TV system, and that is the NTSC for the rest of the world.
When I saw that POP feature, I immediately recognized it. I've seen something similar in a medical waiting room where the largest image displayed a TV signal, the smallest image showed something like a feed of weather and the time, and the "sidebar" showed information related to the office, like wait times for each doctor, etc. I'm not sure if this exact display could do something like that, but I bet it could.
Thanks for the video. Glad to see your enthusiasm. Gonna need it.
What killed my opinion of Smart TVs as a concept was a truly horrible Vizio. You had to be careful when you changed the volume because that was such a taxing activity for the SOC. You could easily crash it by streaming Max and changing the volume.
When using the "free" command in linux, the "available" column is actually the one that's relevant. The "free" column basically says "how much memory hasn't been touched by the OS", but there can be plenty of memory that has been *marked* to be freed by applications, hasn't been truly deleted yet. The "available" column counts all of the memory that *can* be allocated.
Yeah, I was embarrassed to realize later that I'd made such a rookie mistake, but if you look at available its also not doing hot haha
@@CathodeRayDude FWIW even in the "professional" software engineering industry, it seems like most people don't realize it. I had to explain that to a coworker (whom I consider very smart) about a year ago, so you're in good company.
Also, something I do if I have to run a linux where the repos are all dead, is to quickly install the alternative package manager "Nix". It runs on pretty much any Linux and macOS and has most of the packages, and is pretty up to date. I find it generally more reliable than depending on old Fedora mirrors.
I had to explain to a sysadmin just this year about how Linux will use free memory for cache and that you have to take that into account when looking at the memory usage stats.
NTSC 4.43 is for PAL VCRs playing NTSC tapes, while still using the PAL colour oscillator already in the VCR. PAL60 is for using 60hz video signals on PAL TVs that can accept a 60hz refresh rate but not NTSC colour, mainly useful for older video game consoles.
PAL60 should also not be confused with PAL-M, which uses (almost) the NTSC oscillator frequency, and was used in Brazil.
We have these Prometheans (not the exact model slightly newer) in schools in germany.
I work as a School Admin and know these very well. The newer ones allows iPads to connect wirelessly, so students can share their work, the teacher can then at any moment freeze the screen and draw over it to correct or further explain things. Really nice actually. Though we shifted on using Smartboards as the UI is much nicer and they are almost 1000 Euros cheaper. Smartboards have a built in OPS module not that easily accessible, but it still can be swapped or bought with an x86_64 module. All of those, even the new ones still have front io for teachers to plug in their own devices via hdmi, the newest even have thunderbolt 3 inputs on the front and back.
We are going to swap all ops modules with windows 11 compatible ones this year. I love that we can fit 10 year old devices with modern hardware capable of running Windows 11 at nearly a 5th of the price of buying new ones. For schools with limited funds this is insanely valuable!

6:00 IPTV is used a lot in hotels (my industry) to deliver TV service to guest rooms, we call it free-to-guest. Gym equipment with built in displays often have that signal delivered via IPTV as well. You're right, it's just TV delivered via a CAT5/6 cable
Thanks. That's not the spelling I thought he said.
My high school had smart boards and yeah, teachers really didn't like them. They only ever used them as standard projectors for slideshows and just viewed them as permanently occupying whiteboard space and universally preferred the traditional pull-down whiteboard screens that could then be raised back up if they needed the whiteboards. Although in my college classes, one of my professors brings in a drawing tablet and uses that on the projector for everything, so he can save the notes and then share them after class so I guess that's the converse if there aren't smart whiteboards lol
A handheld Wacom tablet is worlds better than having to raise your arm up to a smart whiteboard with high latency, honestly. I bet more profs would share a copy of their notes if they were given a tablet rather than a smartboard.

Seeing the description of the video, thank you Gravis.
Been looking forward to you making a video about these after you talked about them on little guys and it certainly helped to see this today.
2:14 What's funny is that channels normally broadcasting interlaced signals would switch to progressive when showing movies! (at least that's what I discovered when recording DVB signals in Britain in 2006)
Yep, the DVB standard allows for switches from 50i to 25p, this can even be used within individual TV shows. A great example is Top Gear on the BBC which used 50i for it's studio segments and switched to 25p for any pre-recorded VTs.
The value of this new room is solidly proven by (everything up till now and) the pulling the computer out stunt
Time to watch this at 5X speed so that the TVs before they bump the prices up on eBay.
I didn't finish the video before deciding to buy one on Marketplace 😅
Thanks! Ripping off the TV tuner live made me laugh for the first time today. I don't know why. It was just so unexpected.
I have always bought NEC displays as TV's. I use a 40" outside that has survived several hurricanes and a 98" in my family room that has been nothing but a pleasure. Accessing your TV settings through a web browser is just the way.
Honestly, that module system would be really cool for applications such as a Nvidia shield, or a game console like a steam deck dock.
Radio hams would love these old sets to run a spectrum waterfall. I got myself an old POS terminal and it makes a great SDR.
Is that the GUI for the signals received?
It is actually quite common for the tuner in consumer-grade TVs to be a plug-in module as well, so they can sell the same TV around the world and only install different tuners as necessary for each region. It just isn't meant for the consumer to easily swap out. And there are usually settings which can influence the type of de-interlacing used, such as "Game Mode" which sacrifices quality to reduce input lag, or that awful "TruMotion"-type feature which tries to interpolate everything to 60fps or even 120fps.
Chekov’s Slot. Classic Cathode Ray. Here goes the rest of my night.
The digital white board I have at my office not only has HDMI IN on the front panel, but also a full fat USB-C port I'm too lazy to check is thunderbolt, but certainly feels that way. Not only does it do 4K60, but it also passes through any USB devices plugged into the whiteboard (although regrettably not the ones on connected OPS modules, that would have been insane), passes audio to the speakers and the microphones, and enumerates its display as a touch surface AND a wacom display, while delivering 96W of PD. It's insane, and I love it.
Phew! That's convenient, wow. I expected these to just have USB b forever
Thank you for the video, the silence has been deafening all day
Probably been answered already, but as an Aussie who was gaming as a kid in the late 90's and early '00s, PAL60 was a godsend. PAL only refreshed at 50hz,rather than NTSC's 60. PAL60 was supported by many Dreamcast, PS2, OG Xbox and GameCube games to allow them to run at 60FPS on Aussie TVs. Finally, we could play F-Zero GX at the blistering speed it was meant to be played!
I think that second grid you pulled up at 57:40 is for writing Japanese [and presumably other east asian], that's why it has square cells horizontally, one [well, a 2x2 mini-grid] per character.
It's just a grid pattern, when I was a kid all of our math books looked like that, that way you could lay out sums and ensure it all lines up for showing your workings.
FYI: idk if someone already mentioned this, but I am in a district that is all promethean boards (more modern than yours), and the built in screen sharing feature, at least on the modern ones, does support window's built in screen mirroring feature, though not super duper well. For example, if you set the screen mode to extend, the display will only render the pc's extended screen in 4:3 for some strange reason. The neat part about the promethean side though is the ability to have a waiting room where like a class can have all the people presenting connect before hand, and you can live swap who's input is being displayed.The neat thing about the modern promethean OPS modules (and I feel like yours does it too from a side channel video you did a while ago? I could be wrong) is that they completely replace the built in OSD, and also have multiple overlay features on the HDMI inputs, such as a large timer, and an on screen annotation tool, that doesn't require the pc to ever receive the touch input. Our district probably found out when setting these things up initially that the official promethean screen share software is so annoying to use, that they specifically bought these devices that just get mounted onto the back of the board called ScreenBeams, which would handle the usb touch input coming from the USB B cable on the back of the display, and ofc the sending of the connected computer's image to the board. The really strange thing is all of the ones in my district (i've checked at multiple schools) actually come with a FRICKING DOS EMULATOR??? called FreeDosBox... I put the oregan trail on one of them using that, and also windows 3.1 which is really really silly to me lol. Also have poked around the OS a lot, it is way more locked down than the one you have, doesn't have the google play store and you can't load apks. If anyone does want to ask me anything more about how our school district is setup with these/how teachers actually use them, feel free to ask.... I ramble a lot as you can tell lol.
Looking at one again today, I am unsure if there even is an OPS module installed in it, there is a slot, but it looks like it may just be a cover, with a built in grabbing handle. It could be a card, but it has no IO, and the Wi-Fi antennas aren’t located on OPS slot. Instead, they’re on another module in a tiny slot (no idea what standard that is/could be, if it even is a standard) underneath the OPS slot. Heck, it may not even be an OPS slot, it might be the new intel one that was mentioned at the end of the video, tho the slot size does match up with OPS so idk. I don’t know if I’d ever even get the chance to remove the slot to see if their is an actual module or not, since I don’t want to get in trouble for “property damage” or “hacking”.
That OPS android device uses Smart Launcher!
Ive been using smart launcher on my phone for probably over decade, Its definitely using Smart Launcher 3
Hey, just wanted to thank you for your videos and all the crazy cool stuff you bring to the table .... I love the long content and I think the best ones are the videos I look at and go, "WTF?", this outta be interesting and they are always a treat! Have a wonderful day! 😊🌎♥️🕺🐕📺
You know, for years I've been saying PC AIOs should work just like an OPS module (though I didn't know of their existence).
Let you upgrade years down the line, or if the screen is still good you could just get a module with whatever kind of inputs you want.
CEC is a serial communication that allows TVs and devices to talk to each other 2-way to do things like change volume inputs, and synchronize power statuses.
PAL60 ended up being quite common in Europe - it's just PAL but at 60Hz, so if the game you were playing on a game console supported PAL60, you'd get both the resolution of PAL and the refresh rate of NTSC(-ish). I know the Playstation 2 supported it, but it was up to individual games to support it.
I first heard about PAL60 when something on Xbox 360 required that instead of regular PAL 50Hz
If you're European and played on PS2 or Dreamcast (probably the other consoles as well), you probably saw games asking you on startup whether to use 50 or 60 Hz. Usually also including a test mode so you could check what your TV supports.
Just seeing you having so much fun bucking around with the touch screen software made my day.
Thank you for helping me not think about reality for an hour and fifteen minutes.
I’ve read so many books and played so many video games these past two days so as not to fall into the blackest despair
I installed so many of these in different sizes and layouts. PCs of the time couldn't support more than 2 HD screens, so the tiling feature was great for bigger arrays. They had a ton of hours on them by the time they got decommissioned, so buying a used one is a gamble!
Adding a word of thanks for giving us some compelling content on a dark day. It's good to know you're out there being curious and excited about offbeat devices.
LOVED this episode, and it makes me so happy to see how the new setup in the warehouse gives you so much freedom! :D
Needed this right now thanks Dude!!
Our high school started installing paramedian boards right at the tail end of me being there (2008-2009) and they were neat. Basically gigantic drawing tablets with a projector projecting on to them. They did not have touch support and you had to use a pen but they were surprisingly responsive for the time and teachers could email you the notes.
PAL-60 was used in Brazil. Aka PAL-M: exactly the same B&W M standard from the US (bandwidth, channel frequencies) but using PAL color standard adapted M system.
I had a daewoo 32" 16 by nine crt that could do pal 60 and ntsc 50. And rgb 50/60.
I've heard that PAL-60 is a different thing than PAL-M, but I've been unable to figure out what make them different.
@@LordVarkson proper pal-m has different amount of lines(like ntsc, 525)
Pal-60 is the pal(50) just at 60hz(625 interlaced lines). Or its pal-m. Depends on the device.
Only universal tv cards and such tend to support both even if the chips in the devices would.
Pal 60 has a 4.43 MHz color subcarrier, Pal M 3.575611 MHz.
in elementary school i remember that it was always a struggle for the teachers to get the one SMART board that the entire grade was supposed to share. by high school even the oldest construction had SMART boards mounted on the walls. i definitely don't follow the "these things just sit around collecting dust" story, most of my classes were powerpoints that the teachers would mark up while talking. the one time i had a math teacher that actually used a chalkboard it was a genuine novelty
At 12:16 about different color systems, back in 1996 I worked for Samsung and helped design a video decoder chip that could do the usual NTSC PAL SECAM standards and those extra oddball systems as well.
Ok, ok please tell me what the hell PAL60 actually is, cause I've never figured it out. Some people say it's the PAL video format running at 60hz, some say it's NTSC with PAL colour while others have said it's literally just NTSC and they're lying to you.
Wired remote is mostly useful in situations where you have multiple of these facing the same direction but you do not want the remote to control all of them at once. Also you do HAVE to daisy chain dvi for video walls on these. If you run the same video signal with separate cables tiny delays can happen among different displays and it can result in visual tearing especially if the image has fast moving things in it (sports)
I think we all needed this distraction today thank you
Why? Great day and nice video!
There's just something incredibly satisfying about digital whiteboards. I remember in the very early 2000s we had one in our boardroom that worked with a projector and the screen was the size of the whole wall. Drawing on itt seemed like magic to me, although I suspect if I saw it again now it would look very clunky.
14:06 THANK YOU FOR SAVING THE ENVIRONMENT.
We had smart boards at my high school, and the few teachers that used them as a way to provide a copy of the whiteboard online after class and nothing else. Interestingly they used an existing projector as a display.
Some teachers ruined them by using actual whiteboard markers on them.
US doesn't have IPTV to the point you never heard about it?! US is build around coaxial I guess, on top of which the internet was added later as an additional frequency. EU has newer infra, which was internet-first, and TV is added as a service over network (Ethernet or optical), it's just a UDP multicast in many cases, sometimes just MPEG-TS over HTTP.
Also a lot of the US infrastructure is older and saturated, so running TV over coaxial in dedicated frequencies instead of running them all through cable internet makes sense. Although fiber is becoming more common
My school uses these. If you want, i can tell you that there is newer versions of these with at most Android 9 or 10 on them. Also, glad you are covering these! My percussion teacher loaded his with subway surfers, and musical tiles.
IPTV is also how hotels do the in-room TVs nowadays as well
i had a thing for these types of commercial screens, i always wanted one of these with touch screen and a built in pc. I now have 2x 2021 55inch 4k 20point touchscreens from liyama that can house a computer and has android running in the background.
That 75inch is a beast!! awesome video! 😉
23:30 IIRC The game "Dragon's Lair" actually used this feature, basically hijacking the remote capability of its Laserdisc player to skip to specific chapters and frames on the disc
Im the uk those boards are pretty well used, though normally just connected to a PC and then you can write over your slideshow for the lesson, some newer ones don't even rely on PowerPoint/SMARTs proprietry software etc. to handle it right and just overlay the drawing onto the video input if you wants. They also usually come with training for teachers.
At least there is something good to look forward to today. Can't wait to watch. Been looking forward to video on this subject for a while.
Yeah two good things happened today. This video is icing on the cake.
Commercial TVs are THE TVs. My daily driver is a 65in Panasonic plasma commercial display from 2006 and it's an absolute champ, any signal adjustment setting you can imagine for any twisted kind of source you plug into it. The speakers on that, on the contrary, are way superb to any TV I've heard in the past two decades too, but they are basically two column speakers that clamp to the sides of the TV :P Oh, and mine didn't come with a tuner module, so I don't have to pay the NHK tax too!
after these election results, i really needed this video to put me in a non soured mood
Our teachers mainly used these just like those overhead projector screens, just mirroring the computer.
History teacher actually used the whiteboard feature to write notes that we had to copy.
Classrooms with overhead projectors had ActiveInspire installed on the pc
