Study on Video Coding Algorithm of MPEG-4

This paper studies the video coding algorithm of MPEG-4 based on MPEG-4 protocol,especially I-VOP,P-VOP Code algorithms Moreorer,B-VOP.And it provides a simplyer MPEG-4 coding algorithm procedure.The experiment shows that MPEG-4 was higher compression ratio and better image quality at same compression ratio.Compared with MPEG-2,it is more suitable for low-bit network ratio.
