The Studies On Data Compression Algorithm Of Streaming Media Technology

As one of the indispensable media of Internet, streaming media is widely used in Internet multimedia press issue, on-line living broadcast, network advertisement, electronic commence, video order program, long distance education, long distance medical treatment, network broadcasting station, real time video reference etc. compression code algorithm is one of the very important technology. The thesis conducts theory and experimental study in depth focusing on this topic, the main work and the creative fruits may be summarized as follows:1. In order to adapt to the different network bandwidth, the network bandwidth of different users should be considered when coding,2. DCT(Disperse Cosine Transform) based on MPEG-4 is fit for the compression algorithm of streaming media.3. The coder class is defined introducing the object oriented programming, the important member function is realized such as the beginning and end of coding, the getting of image type, the conversion of image type etc. According to the bandwidth of different users, the bitrate is adjusted and the algorithm is simulatively realized.The study and the realization of the algorithm play the active and promotive role in the swift development of the Internet information service such as video order program, long distance medical treatment, real time video reference etc.
