Streaming Media Transfer Protocol

With the development of network technology, Internet which is entitled "the forth media" brings people more information with different forms. Form the appearance of first picture on network to various videos and three-dimensional moving pictures, we gain satisfaction more and more from the network. However, we are facing with inevitably status, that is, size of multimedia files is too big should not be ignored. Because the limitation of network hardware configuration could not meet high require of people. One side, people wish to watch lively and clearly, and the other side, we have to wasting so much time in transporting numerous media data with so slow network speed. In order to solve this contradiction, a new media technology is coming forth, which is "streaming media technology". Streaming media technology is like that, sequence image and audio information are compressed to a number of data packets with compression format, and media servers transport those packets to users' computers continuously and synchronously. And then, users can download and watch media program at the same time, need not download the whole files dada before watching it. Transporting streaming media through network must touch on transmission protocols inevitably. Real-time transport protocols are pivotal technology in the streaming media system. If we adopt suitable protocols, streaming media system will work better, and quality of service will be certified effectively. There are several protocols to support streaming media transmission: Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Resource Reservation Protocol (RSVP), and Real-time Streaming Protocol (RTSP). The several protocols will be discussed and expounded deeply in the paper. At tail part of the paper, a system of embedded streaming media player is analyzed, which is established as a client of streaming media player system. The...
