支持IPTV用户扩容的频道快速切换设计

Design of Channel Zapping Supporting IPTV Subscriber Increasing

随着IPTV业务的迅猛发展,IPTV用户将不断增加,使得IPTV运营商对现有的IPTV业务的设备提出了新要求。该文结合国家"863"计划重大专项大规模接入汇聚路由器(ACR)中的IPTV解决方案,提出一种支持IPTV用户扩容的频道快速切换设计方案,并实现了相关FPGA程序设计。性能仿真结果表明,该方案能够满足IPTV用户扩容的需求。

Along with rapid development of IPTV, the IPTV user will increase continually, IPTV managers advise new demand about the existing devices, based on the solutiont of Access Convergence Router （ACR） of National 863 Plan, this paper presents a scheme of the channel zapping supporting the increasing IPTV subscriber, designs the FPGA program. Performance simulation results indicate that this scheme can fulfill the requirement of the increasing IPTV subscriber.
