Abstract

This method includes: (1) the server end (SE) receives frequency channel (FC) switching request with the old FC info (OFI) and the new FC flow-media address (NFFA) sent by user end (UE). (2) accordingto the result of comparing OFI with the residing server group info corresponding to NFFA, judging that need not to build a new conversation, SE responds UE the FC switching reply. (3) SE receives thenew FC playing request sent by UE and uses the old FC conversation to play new FC media flow toward UE. The method of this invention can be realized on the system and device disclosed in this invention. This invention can reduce the delay time during flow-media FC switching and offers a hi-quality flow-media playing service for users.

Description

technical field

[0001] The invention relates to streaming media technology, in particular to a method, system and device for switching channels of streaming media. Background technique

[0002] In the Internet Protocol (IP, Internet Protocol) mobile communication system, with the improvement of network performance and the growth of user demand, the end-to-end streaming media service is widely promoted and applied. While the media stream is transmitted to the client, the client plays, such as video-on-demand and live broadcast in the mobile TV using the streaming media service.

[0003] In order to ensure that users of streaming media services obtain high-quality services, the 3rd Generation Partner Project (3GPP, the 3rd Generation Partner Project) introduces Packet-switched Streaming Protocol (PSS, Packet-switched Streaming Protocol) technology, which can not only realize the traditional low-speed Unicast (unicast) and multicast (multicast), and can also realize unicast an...
