MPEG explained
Explaining MPEG ... that's easy No? MPEG is the video compression thingie that makes files smaller so you can put them on CD's or DVD's. Close, but no cigar..
Most people that have ever worked with a computer and video files get this far. But what is it really, what does it do, and how does it work ?
In order to be able to exploit the capabilities of MPEG video compression we need to have a basic understanding of what MPEG video compression is, how it works, and why it works the way it works. There is much more involved than simple compression.
In this article I will try to give an overview of the MPEG compression systems and a basic working. As you read on I will go deeper in detail on how the compressor, and decompressor works. You have to understand that MPEG video compression is an extremely complex system based on difficult mathematical algorithms and models.
The additional fact that most of the compression is done in the time domain adds to the complexity of the system, and makes understanding its inner workings more difficult.
