mpeg compression

Mpeg compression

Description

this is the implementation of mpeg2 compression for doing streaming over internet (streaming over IP is not implemented yet) this code might be difficult to understand bcz very little comments have been made.
as you will run it video file will be produced.
some kind of noise appears i have no idea from where this noise is coming. i will be grateful if somebody can sort that out. code has only been implemented uptil quantization part.
news.avi might not get extracted
so here is what you can do
open main44.m
and replace the file name "news.avi" with whatever avi(matlab readable) you have got
