介绍在基于IP技术的CATV前端上实现组播信源全交换的方案实例，该方案经济有效，可对接入平台的不同信号源作实时按需调度，并且各输出端口数据隔离。利用该平台在数字复用加扰系统上实现信源的软热备，不需另加切换设备。

This paper describes a scheme and example of realizing multicast source total exchange in CATV Front-end platform based on IP technology .It is an economical and effective solution .The multicast stream from various sources can be exchanged in real time and the data of the output ports is isolated each other in the plat -form.We have used the platform to realize the hot backup of the different signal source at digital multiplexing and scrambling system , no adding additional switching equipment .
