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...
