Description
Technical field
The present invention relates to the communications field, in particular to a kind of media broadcasting method and system.
Background technology
Based on time-division-multimedia broadcast-multicast service (TimeDivision-MultimediaBroadcast/MulticastService, referred to as TD-MBMS) multi-media broadcasting service refer to based on TD-MBMS technology carrying multimedia service, it is by TD-MBMS broadcast channel, specific time period for user broadcasts all kinds of multimedia service contents.
TD-MBMS multi-media broadcasting service comprises: the business such as stream-type video broadcast, broadcast version mobile phone newspaper, video signal, mobile phone road conditions.
Stream-type video broadcast refers to the audio frequency and video business tine utilizing streaming broadcast mode to issue, such as, central authorities' news hookup etc., terminal receiving television broadcasting or audio broadcasting programme content, present to a kind of broadcast mode of user after parsing; Broadcast version mobile phone newspaper is by TD-MBMS radio network, and transmitting cell-phone is notified breath (text, picture, audio frequency), and then, terminal receives, and issues the display of multimedia message client.As long as support the client of multimedia message and G3, revise a little and expand, just can directly show; Videoconferencing service is also a kind of using graph text information as content presentation, using video film insert as main appearance form, automatically downloads video files by backstage, the application of the novel client that user is easy to use; And mobile phone road conditions real-time broadcast road conditions transport information, towards be also be G3 client.
Multi-media broadcasting service based on TD-MBMS all adopts the distinctive TD-MBMS broadcast technology of TD network to realize service bearer, thus has following characteristics: save Internet resources, with low cost, downloading speed is quick.
Periodic broadcast business refers to that business tine is not that continual broadcast issues, but it is at every turn meaningful when needing to issue, broadcast a period of time, content broadcast is gone off the air after terminating, when by the time having next time new content to need to broadcast, again start the business of broadcast, " news is evening paper early " business of such as mobile phone newspaper, sooner or later respectively there is its every day news item MMS content to need to issue, then generally only need sooner or later respectively once broadcast.
In current TD-MBMS system, mobile phone newspaper and video signal have partial content to be need the carrying out of periodic broadcast to broadcast.General front-end business platform has broadcasting schedule, wherein have, the layout of business tine airtime (comprises the time started, duration), employing be relative time, such as, certain moment terminal receives the broadcasting schedule of certain business, time started is wherein 500 seconds, represents from this moment, goes on the air after 500 seconds.Adopt relative time in broadcasting schedule, instead of the reason of absolute time is, terminal and front-end business plateau time synchronous compare difficulty.
Adopt relative time, owing to following have nothing to do, so the problem that life period is not synchronous terminal time.Create another problem simultaneously, front-end business platform needs the parameter (time started, duration) in moment change broadcasting schedule, implements trouble, what simultaneity factor was transmitted delays the error that also may cause broadcasting schedule, in addition, also add the bearing load of front-end business platform, the parameter in host-host protocol also must revise accordingly according to time variations, such as, with some options that file is relevant, file size, the attributes such as version.Therefore, the more succinct and periodic broadcast method easily of another kind is needed.
Summary of the invention
Main purpose of the present invention is to provide a kind of media broadcasting method and system, at least one of to solve the problem.
According to an aspect of the present invention, provide a kind of based on time-division-media broadcasting method of multimedia broadcast-multicast service, comprise: when have based on time-division-multimedia broadcasting and multicast service needed broadcast time, front-end business platform sends a notification message to the terminal that this business is corresponding; Terminal after receiving the notifying message, receives the content coming from this business of front-end business platform.
According to another aspect of the present invention, provide a kind of based on time-division-multi-media broadcasting system of multimedia broadcast-multicast service, comprise: front-end business platform, terminal, wherein, front-end business platform, for have based on time-division-multimedia broadcasting and multicast service needed broadcast time, the terminal corresponding to this business sends a notification message; Terminal comprises: the first receiver module, for receiving notice message; Second receiver module, for after receiving the notifying message, receives the content coming from this business of front-end business platform.
Pass through the present invention, in time having business tine to need broadcast, front-end business platform notification terminal, after terminal is notified, starts to receive this business tine, solve in periodic broadcast, broadcasting schedule change frequently realizes trouble, system delays causing airtime Watch Error, large problem born by front-end business platform, and then reduce the complexity of periodic broadcast realization, eliminate the airtime Watch Error that system transfers is delayed causing, reduce the load of front-end business platform.
