Embodiment Construction

[0049] In the video conferencing system, when the multi-picture video stream based on the composite code stream is adopted to transmit the multi-picture video stream of the conference, each terminal participating in the conference will receive each sub-picture in the multi-picture. In this way, each terminal can accurately determine the current bandwidth demand of each terminal (including itself) by analyzing the bandwidth characteristics of the video stream of each terminal participating in the meeting; Adjust the bandwidth of its own code stream accordingly; thus, in the video conferencing system, each terminal can complete the balance of the overall bandwidth occupation of the system, so that each terminal can dynamically adjust its occupied bandwidth according to the complexity of receiving sub-pictures , to improve the overall bandwidth utilization of the system.

[0050] The bandwidth equalization method of the code stream in the present invention is designed based on th...

Abstract

In the method, first, anacom is carried out for bandwidth characters of each terminal respectively; then, based on anacom result, calculating settings of bandwidth balance of each terminal; finally, based on calculated settings, relevant adjustment is carried out for own bandwidth for each terminal. Advantages of the invention are: avoiding taking up lot of operation resources, reducing complexity of operation and cost of hardware, in favor of expanding capacity of multi frames by MCU.

Description

technical field [0001] The invention relates to the field of multimedia communication, in particular to a method for equalizing the bandwidth of code streams. Background technique [0002] At present, in the video conferencing system, each terminal can transmit multi-screen video with different content to each other, but in the process of multi-screen transmission, each terminal can only enjoy the corresponding bandwidth exclusively according to the preset ratio, and cannot transmit multi-screen video according to the The complexity of the video dynamically changes the bandwidth it occupies. Therefore, in the process of multi-screen video transmission, since the complexity of multi-screen video changes at any time, the bandwidth occupied by each terminal will not change accordingly, so that the bandwidth of some terminals is in short supply, while the bandwidth of other terminals is idle, which greatly reduces The utilization rate of the overall bandwidth of the video confe...
