Embodiment Construction

[0058]In order to enable multiple media streams from one media file to be played synchronously during multimedia playback, the present invention provides a media resource processor based on a network using H.248, as shown in Figure 1, which includes: A unit, an endpoint creation unit, an identification unit and a synchronization unit connected to the acquisition unit, a demultiplexing unit respectively connected to the acquisition unit, the identification unit and the synchronization unit, and a playback unit respectively connected to the demultiplexing unit and the endpoint creation unit; It may further include an endpoint deletion unit connected with the endpoint creation unit.

[0059] The endpoint creating unit is used to create file multiplexing endpoints and independent endpoints, and establish correspondence between file multiplexing endpoints and independent endpoints.

[0060] The obtaining unit is used to obtain the media file to be played through the file multiplexi...

Abstract

The invention is used for synchronizing several media streams in one media file when playing or recording multimedia file. The playing method comprises: according to the time dependence corresponding to several independent media streams in the media file to be played, the file multiplexing end resolves and distributes the media file to be played; using corresponding independent end to load each independent media stream in order to complete the play of multimedia. The recording method comprises: the file multiplexing end analyzes and converges multi synchronous independent media streams respectively loaded by multi independent end, and saves the converged media file in order to realize the recording of multimedia.

Description

technical field [0001] The invention relates to the field of controlling media resource devices through the H.248 protocol in fixed networks and mobile WCDMA / CDMA networks, in particular to a method and device for realizing multimedia recording and playback. Background technique [0002] Multimedia usually refers to the comprehensive media integrating audio, video, data, text, graphics and images. At present, multimedia technologies are widely used, and typical applications include video-on-demand (VOD) services, multimedia mailboxes, and other services. These services have been widely used in Internet and GPRS networks, and users can receive such services through PCs or mobile phones. Networks under some bearer separation architectures also need to support this service. [0003] In order to support the above services, the ITU-T SG16 standard organization defines the H.248 protocol. The H.248 protocol is a protocol specially used for media resource control, and can be used...
