Backup method for media processing unit, multipoint control unit and video communication system

Abstract

The invention discloses a backup method for media processing units in a multipoint control unit MCU, a multipoint control unit and a video communication system. The method comprises the following steps: a multipoint processor MP in the MCU detects the state of a corresponding media processing unit by periodically polling the status message reported by each media processing unit in the MCU; and ifthe current media processing unit is detected to be out of service, the work of the media processing unit with failure is interrupted through the MP to select a new media processing unit, parameters used by the media processing unit with failure and a corresponding terminal thereof are transmitted to the new media processing unit, and the new media processing unit is started to replace the media processing unit with failure to conduct media service processing. By adopting the method, after the media processing units are out of service, the terminal is called without waiting for the MCU, or theMCU does not need to be called by the terminal, therefore, the latency time of the users is reduced, and the seamless connection at the side of the MCU is realized.

Description

technical field [0001] The present invention relates to video technology, in particular to a backup method for a media processing unit in a Multi-Point Control Unit (MCU for short), and also to an MCU with a multimedia unit backup function and a video service system with the MCU . Background technique [0002] Video service is also called video conferencing service or conference TV service. Video conferencing business refers to a conference that integrates video, audio, and data communications, and can transmit images and sounds of each venue in real time, so that each venue is logically in the same conference. [0003] The whole video service system can be abstracted as attached figure 1 The architecture shown includes gatekeeper GK (GateKeeper), network management platform, multi-point control unit MCU, interactive network and terminal. Users manage meetings through the network management platform, such as opening and closing meetings. The core of the video service sys...

Problems solved by technology

[0009] 1) Regardless of whether the MCU detects the media interruption or the terminal detects the media interruption, it takes a certain amount of time, and the media is related to the network, so the time to detect the media interruption will be relatively long. This longer interruption time will make the user clearly feel the terminal image stagnation;

[0010] 2) When the MCU calls the terminal again or the terminal calls the MCU again, the user can perceive that the terminal has been disconnected, thinking that a fault has occurred, which affects the user experience
