Embodiment Construction

[0059] The solution of the embodiment of the present invention is mainly as follows: the server generates an index file containing the segment files corresponding to the program for each program, and when the client needs to play a program, the EPG module of IPTV obtains the program. Look at the URL of the index file of the program, obtain the index file from the server according to the URL of the index file, and then parse out the segment files of the playback program that needs to be played from the index file, and finally decode and play; The RTSP client can still use the previous method. After the server locates the corresponding fragment file according to the information saved by the system, it extracts the relevant data and forms an RTP packet to send to the client. It is also possible for the server to provide the URI of the index file to the RTSP client, and the server reads the data of the corresponding fragment file after parsing the index file when the client request...

Abstract

The invention relates to a method, server, client and system for recording and playing a replay program of stream media. The playing method comprises the following steps of acquiring a URI (Uniform Resource Identifier) of an index file of the replay program by the client; acquiring the index file of the replay program from the server according to the URI of the index file; parsing the index file and acquiring the URI of each corresponding sub file of the replay program from the index file; and according to the URI of each sub file, sequentially downloading, decoding and playing each sub file from the server. A traditional RTSP (real time streaming protocol) user of the IPTV (internet protocol television) and an HTTP (Hyper Text Transport Protocol) user of the internet can share one record file, a replay function is realized, the storage resource consumption of a streaming media server is reduced, the performance of the server is promoted, and for an operator, the HTTP user of the internet can be supported if the server is only configured with a standard HTTP server without customization, so that the cost is saved.
