摘要
针对有线电视网络,分析了基于IP-QAM和双模VoD技术解决方案。为了避免建设IP回传通道,提出利用GPRS或CDMA手机的WAP功能作为回传手段,形成的一种WAP VoD技术,并进一步借鉴网络VoD的CDN思想,实现了一种不需改造现有有线电视网的广播型VoD技术。
The technologies of IP-QAM VoD and bi-mode VoD are studied under CATV condition,and then the improved method using ADoC is done also. To avoid building IP channel for return, a WAP VoD is put forward,which utilizes GPRS or CDMA mobile＇s WAP function as return channel. Finally a broadcasting VoD technology is come into being according to the idea of CDN in networks VoD,which doesn＇t require any reconstruction of the existing CATV network at all.
