Method for realizing stream media switching and stream media server

Abstract

The present invention discloses realizing stream media switching method. In Cell Multimedia Broadcast (CMB) service, local stream media server receives switching request of starting up local stream media living broadcast from local content management systems, then stopping receiving center living broadcasted global stream media and switching as receiving and retransmitting local living broadcast area stream media; after local stream media server detecting local living broadcast completion, said local stream media server ending local living broadcast service, and switching back receiving and retransmitting global stream media. The present invention also discloses a stream media server, through switching module set in local stream media server to control global / area stream media living broadcast switching and playing. The present invention ensures stream media living broadcast timelinest in CMB service.

Description

technical field [0001] The invention relates to a mobile communication broadcasting technology, in particular to a method for realizing streaming media switching in Cell Multiple Broadcast (CMB, Cell Multiple Broadcast) service and a streaming media server. Background technique [0002] The 3rd Generation Partnership Project Release 6 (3GPP R6) protocol can implement multimedia broadcast and multicast services, but the R6 protocol has not yet been formulated, and it will take a long time for mature products to be launched on the market. Wideband Code Division Multiple Access (WCDMA) products of R99 and R4 protocols have been commercialized, but they can only provide point-to-point live streaming and on-demand services for each user. [0003] In view of this, the prior art provides Cell Multiple Broadcast (CMB, Cell Multiple Broadcast) services, which can implement broadcast / multicast services in WCDMA R99 and R4 protocol products. [0004] The CMB service is a simplified Mu...

When the local streaming media system forwards the streaming media of the center, even if an emergency occurs locally in a certain area, the emergency event cannot be released to the public immediately, which makes the streaming media live broadcast in the CMB business lack of timeliness

[0011] From the point of view of the streaming media live broadcast method in the prior art CMB business, the streaming media live broadcast can only play the content that has been edited, and cannot play new content in real time. Global / regional live streaming cannot be switched. When an emergency event occurs in a certain area, such as emergency announcements, local featured advertisements, local news, etc., the system cannot immediately release the emergency event to the public, making live streaming in the CMB business lack of timeliness. Cannot meet the needs of local users
