Video session terminal, system, and method

Abstract

The invention provides a video session terminal, a video session system and a video session method. The video session terminal is characterized by comprising a central control module, and an audio / video input module, an audio / video output module, a multi-channel audio / video coding / decoding server, a parameter configuration module and a network interface module which are connected with the central control module respectively, wherein the central control module is used for controlling the operation of each module connected with the central control module. The multi-channel audio / video coding / decoding server of the video session terminal can code a multi-channel audio / video signal and decode a multi-channel audio / video code stream. The multi-channel audio / video coding / decoding server can process the multi-channel audio / video signal, so the video session terminal can realize a one-to-many video session. The video session terminal is provided with the central control module, so the video session terminal can directly interact with other video session terminals through a network and can directly acquire audio / video code stream of the conventional monitoring equipment through the network.

Description

technical field [0001] The present invention relates to the technical field of video conferencing, in particular to a video conferencing terminal, system and method. Background technique [0002] Video conferencing is a two-way, multi-point, real-time interactive video application system based on broadband and not subject to geographical restrictions. Video conferencing is also known as conference TV, video conferencing, etc. It can realize the real-time transmission of moving images, voice and application data (electronic whiteboard, graphics) and other forms of information between two points and multiple points. Patent application No. 200820025588.6 in the prior art discloses a video conferencing system. The composition and working principle of the video conferencing system will be briefly introduced below with reference to the accompanying drawings. [0003] see figure 1 , which is a schematic diagram of a terminal of a video conferencing system in the prior art. [00...

AI Technical Summary

Problems solved by technology

[0009] The video conferencing terminal includes a digital audio and video codec board and a central control processing main board, but the digital audio and video codec board can only realize one-way point-to-point audio and video decoding and encoding functions, and cannot realize audio and video decoding and encoding functions between multiple points

And the existing video conferencing terminal cannot preview the audio and video code stream of the existing monitoring equipment (such as DVS, DVR, network camera, etc.)
