| 摘 要： | 文章讨论了基于CATV网络的视频服务器设计,重点对MPEG-2传输流实时软复用、时间戳校正和节目流修改问题讨论,提出了一种“分段均匀交织传输包”的复用算法、复用中时间戳校正规则和节目流字段修改方法及接入控制方法。实验表明,视频服务器能稳定的支持12部MPEG-2节目流播出。

| Abstract: | In this paper,the design of video server on CATV network is discussed,especially focusing on real-time soft-multiplex algorithm of MPEG-2transport stream,time stamp re-vision and stream packet modification.A demultiplex scheme is proposed in the paper.A multiplex algorithm named uniformly multiplex packet in segment is developed.The algorithms of modifying stream packets and time stamp are also discussed.And several admission control schemes adopted in the video server are introduced briefly.The video server is able to play steadily12MPEG-2streams according to the experiments. |
