Problems solved by technology

Due to the powerful performance of virtual reality provided by high-definition video, high-definition video has gradually become the mainstream of today's video conferencing systems, and most of its video resolution supports 720P / 1080P. At the same time, the requirements for network bandwidth are also higher. Using the existing video conferencing system communication method, based on the current domestic public network bandwidth situation, it is assumed that each terminal has an uplink bandwidth of 2Mb / s and a downlink bandwidth of 2Mb / s. Bandwidth, then, using H264 encoding method to realize 720P 30fps encoding transmission, each terminal can only watch one remote video. Remote video viewing

Embodiment Construction

[0016] The solutions of the present invention are described in detail below in the form of specific examples.

[0017] like figure 1 As shown, it is a schematic flow diagram of an embodiment of the information transmission method of the network video system of the present invention, which includes steps:

[0018] Step S101: receive video data sent by each terminal, and enter step S102;

[0019] Step S102: According to the video channel number of each terminal, copy each video data to the sub-window corresponding to each terminal in the current video template, and enter step S103;

[0020] Step S103: Encode the video data of the entire current video template, and transmit the encoded video data to each of the terminals. The encoding here can be various types of encoding methods, such as SVC encoding to meet the high-definition requirements as much as possible. need.

[0021] According to the method of the present invention, by setting a video template, the video template has...

Abstract

The invention relates to an information transmission method of a video conference system and the video conference system. The method comprises the following steps: receiving video data sent by terminals; respectively copying the video data to child windows in a current video template corresponding to the terminals according to video channel numbers of the terminals; and coding the video data of the whole current video template and transmitting the coded video data to the terminals. According to the technical proposal of the invention, after the video data sent by the terminals are received, the video data of the terminals are copied to the small windows in the current video template corresponding to the terminals; then the video data of the whole video template are coded and the coded video data are transmitted to the terminals, so that the coded video data received by the terminals contain all video data sent by the terminals and as the video data of all terminals are displayed on a single video template, network bandwidth can be effectively and fully utilized and the check of a multichannel far-end video can be performed on a single terminal.

Description

technical field [0001] The invention relates to an information transmission method of a video conference system and the video conference system. Background technique [0002] With the development of video coding and network technology, the application of network video is becoming more and more extensive. One of the application methods of network video is video conferencing system. When in use, each user terminal sends the video data collected locally to the server. After receiving it, the server forwards it to all terminals in the video conferencing system or other specified terminals, and these terminals display it after receiving it. Due to the powerful performance of virtual reality provided by high-definition video, high-definition video has gradually become the mainstream of today's video conferencing systems, and most of its video resolution supports 720P / 1080P. At the same time, the requirements for network bandwidth are also higher. Using the existing video conferen...
