Same could be said for human interaction guidelines, there is plenty of
books of ergonomics, not just signal processing.

(Patenting something you can find on a textbook since ages should be
impossible, isn't it?)

Clearly you never ever look at how a codec works or which are it's
constituents or how ffmpeg lays functions in directories ^^;

Same said for h264...

It's easy to come up with ideas of using idct, filter banks, wavelets
and such if you are into signal theory, there are even previous works
about it, many.
