Embodiment Construction

[0014] In the H.323 videophone system, there are many situations of calling between different terminals. As far as terminal A calls terminal B and establishes a normal audio and video call, there are mainly H.225 call process, H.245 capability negotiation, master-slave decision and open audio and video logical channel process, and the two parties transmit audio and video data through the RTP channel .

[0015] The working process of the technology adopted in the present invention occurs after both parties have successfully opened the audio-video logical channel and started to transmit audio-video data through the RTP channel.

[0016] In order to concentrate on explaining the working principle of the present invention, two terminals are used here in the public network, and terminal A makes a point-to-point direct call to terminal B, and the present invention is described (when involving a public network terminal and a private network terminal, And when talking between the pri...

Abstract

A multimedia communication method relates to the communication technology, especially for the multimedia communication safety monitoring. The invention provides a communication method for the multimedia communication safety monitoring, which can realize a safe and reliable remote multimedia communication. The method comprises following steps: a. calling party requesting a connection to a called party; b. the called party performing a safety certification, then establishing the multimedia communication if passing the safety certification; and the called party stopping the communication if not passing the safety certification. The user can apply the system resource furthest.

Description

technical field [0001] The invention relates to communication technology, in particular to communication technology for multimedia communication safety monitoring. Background technique [0002] At present, many terminal manufacturers use the monitored terminal to install service software, and the monitored terminal obtains the MPEG4 real-time video data collected by the monitored terminal through the remote access of the client, so as to realize remote monitoring. Some manufacturers also apply this method to the network videophone system. This method consumes system resources and cannot provide safe and reliable remote monitoring. Moreover, this method is currently mainly used in private networks, and there is no large-scale application. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a communication method for safety monitoring of multimedia communication, which can realize safe and reliable remote multimedia ...
