Embodiment Construction

[0034] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0035] please see figure 1 , a multi-point control unit cluster system provided by the present invention includes a media control server (MCS) and a plurality of media processing servers MPS (MPS1, MPS2, MPS3 and MPS4). MCS is responsible for terminal call access, conference control, media stream forwarding, and MPS scheduling; MPS is responsible for media stream processing, including media stream sending and receiving, audio and video codec, audio mixing, and multi-screen synthesis; MCS and MPS are connected through the network Control message interaction a...

Abstract

The invention discloses a multipoint control unit cluster system and method. The system is composed of a media control server (MCS) and a media processing server (MPS). The MCS receives conference information sent by a conference management server, and allocates one or more Multiple MPS for the conference. The MCS multicasts or unicasts the received media streams of the terminals to all the MPSs that provide media processing services for the conference. Each MPS is responsible for the media processing of some of the terminals, performing audio mixing or multi-screen synthesis, and encoding The final media stream is sent to the MCS, and then forwarded to the corresponding terminal by the MCS. When the MCS discovers that an MPS is offline or needs to be maintained, the MCS saves the call information responsible for the MPS into a list to be processed, and migrates the calls to other available MPS one by one, and the terminal calls are still maintained. Connection Status. The invention can solve the problems of media stream delay and audio and video quality degradation caused by MCU cascading, and has simple control logic, high reliability and fault recovery.

Description

technical field [0001] The invention belongs to the communication field, and relates to a capacity-expandable video conferencing system and method, in particular to a multi-point control unit cluster system and method. technical background [0002] Video conferencing systems based on H.323 or SIP international standards have been widely used. Due to the adoption of international standards, video conferencing equipment from different manufacturers can be interconnected, which is convenient for users to expand capacity and effectively protects users' investment in video conferencing equipment. The multipoint control unit (MCU) is the central control device of the video conferencing system. The MCU sends the signaling of each conference site to the multipoint controller (MC) to complete conference control and other processes. Send the media stream to the multipoint processor (MP) to complete the corresponding audio mixing or switching, video multi-screen synthesis or switchin...
