Embodiment Construction

[0024] The implementation process of the bandwidth control method of the video conferencing system of the present invention will be described in detail below through specific embodiments.

[0025] see figure 1 , in the video conferencing system bandwidth control method of the present invention, the basic architecture of the video conferencing system used is as follows figure 1 As shown, the video conferencing system includes: terminal A, participating terminals B, D, E, F, N, etc., and a processing module for processing multiple image signals to be transmitted provided by each terminal for transmission . Wherein, the terminal A is operated by the moderator, and the terminal D is operated by the sub-moderator, and the processing module is usually set on a network server to exchange information with each conference terminal through the network. Since the technology of transmitting information through the network is familiar to those skilled in the art, it will not be described...

Abstract

The invention provides a bandwidth control method of a video conferencing system. The method comprises the following steps: a parameter setting module is provided by a terminal with priority so as to lead an operator to set area division mode of a display screen of the terminal and respective transmission characteristic information of image signals needing to be displayed by all the display areas,wherein the transmission characteristic information is information for limiting the bandwidth of the image signals to be transmitted correspondingly; then the respective transmission characteristic information of image signals to be transmitted is determined by a processing module according to the setting of the operator; processing of coding and the like is carried out to the image signals to betransmitted so as to lead the image signals to be transmitted to occupy different bandwidths, thus being capable of realizing flexible control to the bandwidth of multiple image signals in the videoconferencing system and effectively solving the problem that the occupied bandwidth of the existing video conferencing system is overlarge.

Description

technical field [0001] The invention relates to a video conference system, in particular to a bandwidth control method of the video conference system. Background technique [0002] With the development of computer networks, network video conferencing systems have been widely used in various industries. By holding a video conference, large-scale training activities or meetings can be carried out at any time. All participants can easily see various information on the computer screen of the conference host as long as they receive video and audio information in front of their computers, and can Realize real-time, face-to-face communication and interaction among participants, which greatly improves work efficiency and saves working time and conference expenses of participants. [0003] Usually, in a conference, a terminal needs to receive about 4 to 8 channels of video images transmitted by other terminals. After adding its own video, the number of video channels required to be ...
