NOVA:A P2P-Cloud Vod System for IPTV with Collaborative Pre-deployment module based on Recommendation Scheme

摘要

To solve the problem of the bandwidth bottleneck in the traditional IPTV Vod system during the peak hours, the NOVA system is designed which is a P2P-Cloud Vod system with collaborative pre-deployment module based on recommendation scheme, according to the particular user behavior and the regionalization deployment of STBs. The NOVA system pre-deploy 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 experiment shows that the bandwidth can be reduced by more than 20-40% during peak hours by NOVA.
