Live time-shift system based on P2P technology and method thereof

摘要

The present invention provides a live time-shift system based on the P2P technology and a method thereof. The system includes a coding server, a live server and a control server arranged at a server end. The method includes: splitting, by the coding server, a received live video data stream into fixed-size live video packets; and then adding live channel information and time information to each of the live video packets; issuing the coded live video packets to the live server, and sending current control information to the control server; continuously obtaining, by the live server, the live video packets from the coding server; upon requesting viewing of the video data, first sending, by the client, a video request to the control server; returning, by the control server, storage information of the video data to the client, and obtaining, by the client, the video data through an established data link. Both of the server and the client of the present invention support the live time-shift function based on the P2P technology, which may support mass parallel applications.
