yash patel Hi! LZ78 is better than LZ77 as in encoding we use doublet in LZ78 whereas triplet is used in LZ77. So compression is better in LZ78 than LZ77.
1. The LZ78 algorithm attempts to work on future data whereas The LZ77 algorithm works on past data. 2.In LZ77 the encryption process is time consuming due to the large number of comparison done to find matched pattern. LZ77 doesn’t have its external dictionary which cause problem while decompressing on another machine. The LZ78 is a dictionary based compression algorithm that maintains an explicit dictionary.
You explained so well.
great teaching style
maybe this is not relevant here but I have this question that how this algorithm is a data compression algorithm since all the symbols are here.
Even i am wondered because this is simply rearranged
what will be the table if we will not have any special symbol ? will it be normal increasing order?
Thanks for uploading all dcdr videos
👍
What if there are more than one special character? how can we arrange them in lexicographical order?
AVNISH KUMAR Hi! We arrange them according to their ASCII code. Thanks
Which one take first between special characters and normal letter??
Thanks
In text data compression which one is better BWT OR MTF ALGO
bhaut bhadiya yr.. tysm
Thanks 😊
Which is better method in lz77 and lx 78 which is better justify ma’am

itechnica thanks
itechnica for decoding
During cyclic shift you are shifting first character last .
Can we shift characters on right side ??
In my book it is given like that so I am lil bit confused
@@pateldhruvil4616 yes
thnx for video
Thank you but 1 2 and 3 is not fully vsible
Hi! increase the quality from setting.
itechnica kindly check ur mail for the question
mam please 🙏make a video on the distortion criterion my exam in this month please make this video as early as possible
I want another answer can you ma’am

Didi ap hindi me he bana lo video yar...
Why you are worrying so much 😅😅😅
Madam bad explaination :-(
