Abstract

The invention provides a network live broadcasting system with playback function and a player for solving the problem that the current live broadcasting system cannot realize random time-length playback. The system comprises a stream media server and a client, wherein the stream media server comprises a cache module for caching the received live broadcasting video. The system can distinguish the live broadcasting request and the playback request sent by the client; and when the client requests for playing back the played live broadcasting video, the stream media server can transmit the corresponding video data to the client from the cache so as to perform unlimited long-time live broadcasting playback. Moreover, the cache can accurately position a key frame by adopting the stream slicing technology and performs playing from the position of the key frame so as to realize low-delay network live broadcasting.
