摘要： The present invention provides a method and a system for implementing media interaction of the IPTV. The method includes: a user terminal sending a request for a TVOD media file or a TSTV media file to a marginal stream media server in a marginal P2P area in which it resides; the marginal stream media server which is requested sending the first data block of a target media file to the user terminal; the user terminal playing the first data block of the target media file immediately after receiving the first data block of the target media file, at the same time, requesting a content delivery network agent in a P2P area of a terminal side in which the user terminal resides for an information list of content delivery network nodes capable of providing subsequent data blocks of the target media file; the content delivery network agent returning the information list of content delivery network nodes capable of providing the subsequent data blocks to the user terminal; the user terminal requesting to download and play the subsequent data blocks of the target media file. The present invention possesses advantages of high service quality, mitigating the pressure on the center stream media server and the marginal stream media server, and reducing the construction cost of the system
