The invention provides a region-oriented set top box P2P-Vod system and method. The system includes a set top box terminal system and a server subsystem. The set top box in the set top box terminal system is divided into a plurality of regions, and a overlay network is formed by the regions through DHT. The server subsystem is used to acquire historical playing information of each region, extract a recommended film or episode list of each region according to the historical playing information, and pre-deploy the films or episodes corresponding to the recommended film or episode list to the set top box in the region. The system further includes a film resource storing and forwarding subsystem for storing recommended films or episodes required by a video-on-demand server. The resource storing and forwarding subsystem is used to store film or episode resources in the cloud end, and perform edge distribution through the CDN service. The server subsystem further includes a recommend server and a video-on-demand server. The recommend server and the video-on-demand server are used to perform dynamic deployment at the cloud end.
