To solve the problem of the bandwidth bottleneck in the traditional IPTV Vod system during the peak hours,the STB-Video system is designed which is a P2P Vod system with collaborative pre-deployment module based on recommendation scheme,according to the particular user behavior and the regionalization deployment of STBs.The STB-Video system pre-deploys the VoD contents which are recommended on the STBs of the region during idle hours,and the STBs in the same region strengthen data collaboration using P2P protocol which results in the reducing of the bandwidth of the VoD server.The experimentation shows that the bandwidth can be reduced by more than 6％-30％ during peak hours by STB-Video compared to the Zebra system.
