一种支持DVBCAS的网络时移电视实现方法及其系统
摘要：
本发明提供一种支持DVB CAS的网络时移电视实现方法及其系统，其避开具体CAS特点，采用通用的逻辑方案，实现了对不同CAS的统一处理，适应现有DVB-C或IPTV数字电视业务采用多种CAS的现状。本发明的一种支持DVB CAS的网络时移电视的实现方法，至少包括一适用于TVS网络服务端的支持DVB CAS加扰的单节目流数据的时移处理方法；一同时适用于基于IPQAM接入和基于以太网接入的DVB CAS网络时移电视实现方法和适用于DVB CAS网络时移电视的客户端软件实现方法。根据本发明的支持DVB CAS的网络时移电视实现方法及其系统，能够克服网络时移电视对DVB CAS加扰节目处理上的难题，解决网络时移电视在数字电视推广环境下的瓶颈问题。
摘要（英）：

The invention provides a method and a system for implementing network time-shifted television supporting DVB CAS, which avoids specific CAS characteristics, adopts a general logic scheme, realizes unified treatment for different CAS and adapts to the present situation that the prior DVB-C or IPTV digital television services adopt a plurality of CAS. The method for implementing network time-shifted television supporting DVB CAS at least comprises a time-shift processing method which applies to TVS network servers and supports DVB CAS scrambling single-program stream data, a network time-shifted television implementation method simultaneously applicable to DVB CAS based on IPQAM access and Ethernet access, and a client software implementation method applicable to DVB CAS network time-shifted television. According to the method and the system for implementing network time-shifted television supporting DVB CAS, the problems of the network time-shifted television in processing DVB CAS scrambling programs can be overcome, and the bottleneck problem of the network time-shifted television in the environment of popularizing digital television is solved.
