Embodiment Construction

[0040] Please refer to FIG. 2 , which is a structural diagram of a session model established by the media processing device in the first embodiment of the present invention. Two real-time streams are established between the media processing device and the multimedia source: video stream (Video) and audio stream (Audio); Processing and association according to time, processing according to the format indicated by the media control device, and generating expected files.

[0041] Please refer to shown in Fig. 3 again, a kind of flow process of the method for realizing multimedia recording by H.248 agreement of the present invention is as follows:

[0042] Step 1: Establish a video and audio channel between the media processing device and the recording data source, and negotiate a common support capability; the media resource control device needs to instruct the media resource processing device to complete the negotiation of the following information:

[0043] (1) IP address, por...

Abstract

A method for recording multimedia through H.248 protocol includes setting up multimedia channel between media processing unit and recording data source and then indicating media resource processing unit to start up multimedia record by media resource control unit. The system used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to a communication system, in particular to a method and system for realizing multimedia recording through the H.248 protocol. Background technique [0002] The multimedia recording process refers to the process of recording video and audio through camera equipment and storing them on some storage media. At present, devices such as video cameras and mobile phones containing cameras all have this function. [0003] Used on communication network equipment, the camera data can be collected through the communication terminal, and the camera content can be stored on the storage device of the communication network; in this way, functions such as multimedia mailbox message and multimedia video storage can be realized, thereby realizing multimedia Message function. [0004] In a network device with a separate architecture for media resource processing and media control, such as a WCDMA IMS (IP Multimedia Subsystem, IP Multimedia Subsyst...
