Mean removal is another one of those concepts– like differential coding— that sounds like it would be difficult to understand. It’s not.

Video Coding Concepts: Differential Coding
This article is now expanded and maintained at http://wiki.multimedia.cx/index.php?title=Differential_Coding.
Differential coding explained:
1 + 1 = 2
Got that?
Video Coding Concepts: Run Length Encoding
This page is maintained in Wiki format at http://wiki.multimedia.cx/index.php?title=Run_Length_Encoding
I may as well start this series of articles off with what is perhaps the simplest multimedia compression technique of them all: run length encoding (RLE). The basic idea behind this concept is to encode information about runs of identical numbers rather than encode the numbers themselves.
Know Your Video Codec Concepts
A rather alarming fact came to my attention recently: There are people out there on the internet who actually learn everything they know about multimedia technology strictly from the information provided at multimedia.cx.
So I thought maybe I should write some articles about core multimedia concepts. Things like the discrete cosine transform, vector quantization, Huffman coding. The fact is that there are already countless pages out there that cover all of these concepts. What could I add?
