Can zooming technique be used to compress data for transmision. For example a 300 pixel by 300 pixel zoom down to 3 pixel by 3 pixel size but instead of digital we use true color raster image formats or png. Same for sound and voice we use some wave in graphical image and zoom it down mili second wave at milivolt scale for encoding we could save billion dollar in airtime a day

okay, this is kind of wierd. im really interested in compression and all, but hey, i swear I'll send you a private video of my girlfrind saying u-u the boss! - if you can tell me how old carrie ann is. Been searching for is for like 17 minutes, which is as long as I've ever taken to look for some info on google. Really, how old is she?

I'll stick with WAVs and BMPs, thanks. I will only use MP3s and JPGs when absolutely necessary or when quality doesn't matter (which is rare. There are some things you simply do not compromise the quality on, whether you can see/hear the finer nuances or not. Lossless compression ONLY over here, if ever.

In reality, at least for me, Huffman (or any -grossly- variable length codes) are a pain. They are not really critical and a much simpler encoding scheme can be used. They do save a little storage space but not much compared to some simpler schemes.

Found it weird that you grouped blocks of two different colors before you just make a pallete. There's 3 colors so thats 9 bytes + 16 - 2 bits = 13 bytes. I guess it was to show off the binary tree thing but the example seemed a bit off.

-Are all those compressions methods available in our Famous WinRAR-?
Or are we supposed to use another one that is more specialised?
Can you suggest. ?

I was watching SILICON VALLEY then i started wondering what is compression i know the basic idea but how do we implement it. Then another movement i am here -

4: 34 Ahhh! You made a zombie stick figure!
In all seriousness, thank you for this excellent video! Great content! Can't wait to learn more from you.

Now we can hide a huge amount of absolutely useless data into an extremely small box. What will be the next level of abstraction!
