The Demultiplexing Algorithm Analysis And Implementation Basing On The AVS

With the rapid development of the computer technology and communication network, multimedia communication plays a more and more important role in People’s Daily life. Especially in the recent 10 years, with the explosive development of Internet technology, and communications technology, multimedia communication era is coming.AVS is the fully Intellectual Property of second generation Source Coding—Decoding Standard, owned by China. But pure video stream only can be played orderly, and can not be randomly accessed or played in the network. File format is designed to solve these problems.Firstly, the paper expounds the multimedia communication system architecture, the key technology used in our daily life.Secondly, the paper introduces the common multimedia file formats, and the MP4, MPEG2-TS are described in detail.Thirdly, the paper puts forward a new algorithm on how to demultiplex the MP4 and MPEG-2 TS file. The new kind of algorithm is realized based on C21100. Through the experiments, we have proved that the MP4 stream and MPEG-2 TS stream can be played smoothly and you will fell no pause even if you randomly seek the stream.In the end, the paper has compared the advantages and disadvantages of both formats. The experiments shows that the MP4 file bring lower data redundancy.
