| Abstract: | Currently, video compression technology has been widely concerned and used in many fields. Firstly, this paper analyzes the necessity and possibility of video compression. Secondly, it discusses two ways of video compression from two aspects： redundancy compression and information compression. Finally, it analyzes and compares the existing video compression standard systems and theories. The research shows that H.264 （MPEG-4 AVC） and JPEG2000 will become the main parts of the video compression technologies in the future and at the same time, H. 264 gets higher compression performance and has better network adaptability and it is the main developing direction. |
