A P2P Streaming Media Segmentation Method Based on Scalable Video Coding Data Characteristics

P2P Streaming Media System Based on SVC(Scalable Video Coding) often use equal playback length segmentation method to segment the video data, but the size of the data in different segmentation varies widely using this segmentation method, which can lead to the instability of data transmission in P2P network system. In this case, this paper presents a new segmentation method based on SVC. In the new method, the video data is segmented twice, first segment the video data of each layer according to the number of GOPs(Group of Picture) which should be contained in the segmentation of each layer, and after first segmented, the segmentation of the same layer have the equal playback length, then segment the segmentation of the base layer using the second segmentation method. Finally the experimental results show that the new segmentation based on SVC can reduce the complexity of the enhancement layers scheduling in P2P system and enhance the stability of data transmission in P2P network system, and it is a kind of effective P2P streaming media segmentation method.
