摘　　要：设计和实现了一个支持时移电视业务的机顶盒终端软件模块.软件实现上,采用服务端缓存直播电视的节目内容,终端软件模块通过应用层协议控制服务端节目内容发送的方式.该实现分别消除和降低了对机顶盒硬件的依赖和成本,软件实现的模块化使得时移功能方便的集成到其它机顶盒中,具有通用性.实际运营结果表明,该实现能够有效的降低系统部署成本,兼容不同类型的机顶盒,适合于大规模时移电视的运营.A set-top-box software module supporting Timeshifting TV service was designed and implemented. Based on server-side cache of broadcasting content, timeshifting function was implemented through set-top-box application layer protocol that controlled stream delivery of media server. The software approach eliminates the hardware dependency and lowers the cost of set-top-box, and the timeshifting software module can easily be integrated into any third-party set-top-box. The results of experimental business management prove that the proposed scheme can greatly reduce the cost of large-scale system deployment and works in various kinds of set-top-box.
