Research And Practice Of MPEG-4 Delivery Means Based On RTP

With the extensive application of Internet, the requirement for multimedia communications grows more and more strongly. The appearance of MPEG-4, which is the new generation standard based on coding of audio-visual objects, has met the needs for the current development of multimedia. In fact, it is growing as the main technology of multimedia delivery. The standard only gives a Delivery Multimedia Integration Framework (DMIF), and doesn't define the specific realization details aiming at every kind of information network. In the face of current extensive use of Internet, it is especially urgent and significant to make some research on MPEG-4 delivery means based on IP network.What is introduced first in this thesis are MPEG-4 system architecture, real-time streaming protocol in the MPEG-4 standard and the present research on MPEG-4. And on basis of the introduction, the thesis goes on to anatomize the DMIF. Then present a feasible scheme for delivering the media data of MPEG-4. In other words, the thesis emphasizes the research on how to implement the data plane of DMIF, namely, on the methods of how to deliver the media data of MPEG-4 and devise an effective packeting algorithm to guarantee the effective delivery of the media data of MPEG-4. Finally, we implement the scheme, and the testing results indicate that it can accurately and effectively deliver the media data of MPEG-4.
