Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 2 to Figure 7 In the shown transmission structure of the audio and video code stream in the multimedia video conferencing system of the present invention, the audio and video code stream is directly transmitted between each participating node including the information publishing end node, and the MCU is only responsible for sending the status monitoring command, so that the MCU It no longer becomes the bottleneck of the whole system.

[0032] from figure 2 It can be seen from the transmission structure of the audio and video code stream in the first multimedia video conferencing system of the present invention that this solution requires the information publishing end, that is, node A in the figure, to have a sufficiently large output bandwidth (out-degree). Therefore, although the program will MCU such as figure 2 What is shown is li...

Abstract

The method features a direct transmission of audio and video bit-stream between the information releasing terminal node and each node relating to the conference, in which MCU only is in responsible for transmitting the state-supervising instructions. It comprises: 1) determining the main control end and information releasing terminal node; 2) detecting the size of output bandwidth between the information releasing node and each node relating to conference; 3) according the size of bandwidth of the information releasing terminal node and the size of bandwidth of nodes relating to the conference, constructing a hierarchical transmission structure composed of MCU.

Description

technical field [0001] The invention relates to a multimedia video conferencing system, in particular to a method for transmitting audio and video code streams in the multimedia video conferencing system. The method is applicable to network conditions with limited bandwidth and is an effective technical solution for the bandwidth bottleneck problem. Background technique [0002] The multimedia video conferencing system connects multiple multimedia video conferencing terminals located in different places through the IP network. Carry out two-way communication to enhance the realism, effectiveness and interactivity of people communicating in different places. [0003] The multimedia video conferencing system requires the information publishing end to distribute video information to all participating terminals; at the same time, the information publishing end can monitor and watch each or more participating terminals at any time according to the demand, that is, the master cont...
