specific Embodiment approach

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described below in conjunction with the accompanying drawings. The specific embodiment of the present invention is:

[0021] 1. Large-capacity media server system

[0022] In the softswitch system based on the carrier grade, the system capacity is a very key system performance index. At the present stage, the processing capability of a single MCU is generally 64 channels of video information. In order to solve the capacity problem of the media gateway system, it is necessary to study the large-capacity video signal DSP processing technology and the high-performance CPU application technology. Among them, the high-performance CPU mainly handles the real-time control transmission protocol and the media gateway control protocol based on H.248.

[0023] 2. Network load balancing technology

[0024] There may be multiple media servers that can complete the connection to v...

Abstract

This invention relates to a multi-points control unit (MCU) of a video conference system based on the network soft exchange structure system of the next generation with the characteristics of applying the layer interface technology of the soft exchange standard and normalize the separation of the functional modules of the multi-points controller in MCU of the video conference system and the multi-poitns processor to put them in the third and fourth layers in the mext generation of a network system structure and to broadcast or organize the broadcasting into the network in the way of stream medium of the images, sounds and data of video conferences by introducing the stream medium technology so as to meet the needs of products of telecommunication video conference with large volume and high reliability.

Description

technical field [0001] The invention belongs to a multi-point controller of a video conferencing system satisfying the next-generation network, and is specifically a multi-point controller of a video conferencing system based on a soft switch. Background technique [0002] The video conferencing system can provide multimedia communication services integrating voice, video and data. Its appearance greatly facilitates people's communication and communication, and has become an important driving force in the communication market. So far, the development of the entire video conferencing system by telecommunication companies has not yet formed a scale, and it will undoubtedly be the general trend to carry out the operation of the video conferencing system facing the public. As a modern communication equipment development company, we have seized this favorable opportunity through technological and operational innovation, and started to develop a video conferenc...
