ATSC 3.0 Is The Internet, Without An Internet Connection

In an age where more people are looking at Elon Musk tweets rather than watching a conventional TV network like NBC, broadcasting additional data over-the-air along with TV and radio, could be the next generation of serving the public interest, using the public airwaves. While many people think of ATSC 3.0 as a broadcast TV standard, ATSC 3.0 at its root is simply a standard that broadcasts internet protocol data to the masses. Just like how you can stream live TV, load a weather app, and listen to podcasts using the internet, ATSC 3.0 could do the exact same thing, without an internet connection.
*Correction: The preamble was incorrectly labeled as Low Level Signaling in the video. The preamble is what tells the device the PLP structure, modulation and code rates, etc. Also, the preamble does not have an IP address. The IP address shown in the video is indeed the IP address for Low Level Signaling, it's just not sent at -7.8 dB. Low Level Signaling is sent in the payload with the PLPs, while the preamble (containing L1 Basic and L1 Detail) is sent separately. L1 Basic and L1 Detail are sections within the preamble and can be sent using different robustness levels respectively if the broadcaster wants. This means there may be portions of the preamble sent at a higher SNR than -7.8 dB.

this now includes DRM in most part of the usa

Give us back analog TV any day of the year over ATSC 3.0. I would even take ATSC 1.0 being reimplemented with orthogonal frequency division multiplexing over the complexity and utterly uncalled for implementation of digital rights management scrambling the signal.

ATSC 1.0 is not great for watching TV in buses or boats or any moving vehicles.

[@scratchpad7954]

@@FrancisLitanofficialJAPINOY My point precisely. OFDM is part of why you can call someone on a cell phone while a boat is sailing around in the harbor of a city like New York City or Los Angeles, and good old AM/FM is why you can listen to the radio aboard a moving vehicle.

3.0 is dead on a arrival networks got greedy and started encrypting everything I don't think anyone's really excited about it anymore everyone staying with 1.0 including TV manufacturers. Maybe in 10 or 15 years we may be forced to adopt 3.0 but I doubt it.

Problems with ATSC 3.0 NEXTGEN-TV:
* FCC will force close all ATSC 1.0 stations in the future killing your old TVs.
* FCC requires only 1 free main OTA channel and all sub channels can be DRM pay per view etc.
* FCC rules that 5 percent of old ATSC 1.0 coverage area does not need to be covered anymore = (SHORTER RANGE).
* Currently no 4K and you only get the main channel and no sub channels.
* OTA ATSC 3.0 is better but is not perfect and still can be affected by weak tv signals: ( weather, planes, trees, buildings, trucks, poor antenna, etc).
* You may need home pay internet for updates and to unlock DRM encrypted ATSC 3.0 tv channels.
* Viewing zone outside of your 15 minute city or town could be blocked.
* Your TV viewing habits could be tracked by your serial number or IP address.
* ATSC 3.0 is updatable until it is not updatable without new hardware tuners (ATSC 4.0, 5.0, 6.0, 7.0......).
(IMO September 2023).

I dig this thanks for the video

[@smitty9398]

DRM = No

[@phillipjames453]

I don't recall anyone asking for this.

[@madmax2069]

​@@phillipjames453about the only ones that asked for it are the broadcasters, either to try to make a few more dollars, or to basically destroy OTA and force people to streaming.

[@jacobburns9343]

ATSC 3.0 is amazing, the only negative is broadcasters planning to use it for... 🔒.

[@davidsradioroom9678]

There is a lot more to 3.0 than I imagined.

[@my-yt-inputs2580]

Just let me record my OTA programs.
