摘要
在MPEG-2TS流播出服务器和多路数字卫星节目收录服务器的基础上,设计了一种基于实时收录系统的多路卫星节目转播服务器,通过卫星节目收录系统,将收到的多路实时卫星节目在服务器内部进行选择、切换和复用,然后通过ASI接口转发到HFC网络。测试表明转播服务器能够稳定地进行节目转播,节目之间切换流畅。
Based on the MPEG-2 TS stream broadcast server and the multi-channel satellite program collection server, a multi- channel satellite rebroadcast server is proposed by using real-time collection system. This rebroadcast server can choose, switch and multiplex the received satellite program, and then retransmit the program to HFC network through ASI interface. The test resuits show that the server can rebroadcast the programs stably and switch the programs smoothly.
