A stream media system, signaling forward device and stream media transmission method

Abstract

The disclosed flow media system comprises: a signaling transmission system, including an authorization unit to report request to following system and receive result to send to a media server, and a transmission unit for transmit signaling flow; a business support system, including an authorization unit to authorize the terminal and send result to last device; and a media server to transmit media flow to terminal after authorizing successfully;. This intention transmits signaling flow and data flow separately to make the media server focus on its self function.

Description

technical field [0001] The invention relates to the field of streaming media, in particular to a streaming media system, a signaling forwarding device and a streaming media sending method. Background technique [0002] At present, in the field of IPTV (IPTV, Internet Protocol TV or Interactive Personal TV), CDN (Content Distribution Network) and mobile streaming media, on-demand media files are sent from the media server to the terminal through unicast. Provide services. The signaling flow and data flow are directly interacted between the media server and the terminal, and all signaling messages are independently managed by each media server, and charging information is reported. [0003] In the streaming media system, the RTSP protocol (Real Time Streaming Protocol, real-time streaming protocol) is used between the terminal and the media server based on the TCP protocol (Transfer Control Protocol) to perform request or response signaling interaction. A complete RTSP inter...

Problems solved by technology

[0012] From the above processing flow when the media server provides media services to the terminal, we can see that the signaling flow is directly interacted between the terminal and the media server, and the signaling interaction is scattered, so it is impossible to achieve unified management, current status, playback success rate and other information Unable to collect in real time;

[0013] At the same time, the media server also needs to report additional billing information to the business support system, which affects the performance of the media server;

[0014] In addition, since all signaling control messages directly interact with the media server, if the media server needs to interface with different terminals, it needs to adapt to different signaling control protocols, resulting in the need for complex modifications when the media server implements the interface with multiple terminals;

[0015] And it can be seen from the above process that each media server interacts with the terminal independently, and there is no relationship between different media servers, so it is impossible to achieve load balancing between different media servers
