Multi-point control unit of video conference system and video processing method thereof

Abstract

The invention discloses a multi-point control unit of a video conference system, and a video processing method thereof, wherein the multi-point control unit of the video conference system comprises a video processing unit which comprises a plurality of universal port units, the universal port units are connected with a plurality of terminals of the video conference system via an Ethernet interface, the universal port units are respectively used for uncompressing compressed video data of one terminal from the video conference system, and send the uncompressed data to an Ethernet exchanger; andthe Ethernet exchanger is connected with the universal port units via the Ethernet interface to form an internal Ethernet which is used for receiving the uncompressed data sent by the universal port units. The invention realizes the universal port function on multi-point control unit media processing of a video conference, and networking based on the Ethernet technology has better stability, lower cost, easy capacity expansion and stronger compatibility.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multi-point control unit of a video conferencing system and a video processing method thereof. Background technique [0002] A video conferencing system refers to a system that can realize real-time interaction and transmission of multipoint video and sound, and is usually composed of a background conference management 105, a multipoint control unit (MultipointControlling Unit, MCU) 104, and terminals 101 at each point, such as figure 1 shown. [0003] The background conference management is used to realize the function of conference management, which can be carried out through the Internet; the MCU completes media processing and other functions according to the conference requirements; here, the terminal refers to the equipment of one party participating in the conference, including the camera, video receiving and display, microphone , loudspeaker and other terminal equipmen...

AI Technical Summary

Problems solved by technology

[0012] 1) Chips with Rapid IO interfaces are more expensive, costly, and not common enough, and the narrow choice leads to limited specific implementation methods;

[0013] 2) Although the Rapid IO interface (an on-board technology) supports customized copper-axis cables for transmission, its length is limited, generally within a few meters, which limits its application space;

[0014] 3) Rapid IO has relatively high requirements on board layout and routing, and the network stability is poor. Since Rapid IO is mainly used for intra-board interconnection, there is a relatively high technical risk in forming a complex network between boards.

[0015] To sum up, the problems of the above solutions are mainly the problems of high cost, narrow chip selection, limited application range, and high technical risk of forming a network by using Rapid IO. These problems are not conducive to video conferencing systems. expansion and smooth upgrade
