Construction Architecture and Key Technology Application of Video Communication System Based on MPEG
This paper discusses the construction architecture and key technology application of video communication system based on Moving Pictures Experts Group(MPEG)video coding standard.Firstly,the development of MPEG series standards(including MPEG-1,MPEG-2,MPEG-3 and MPEG-4)and their important role in video communication are introduced.Then,the architecture of video communication system based on MPEG standard is described in detail,including front-end acquisition,video coding,network transmission,decoding display and other key links.In the part of key technology application,the latest progress and application examples of MPEG video coding technology,network transmission protocol,real-time processing technology and error control strategy are analyzed,and the advantages of MPEG-based video communication system in improving video quality,reducing transmission bandwidth requirements,enhancing real-time and stability of the system are summarized.The future development trend is also prospected.
