Embodiment Construction

[0036] The multi-channel video communication method and system disclosed in the present application adopts an independent video codec for each connection channel, and establishes a relationship table between video rate-distortion characteristics and video encoding parameters for the video codec, according to the network of each connection channel. Adjust the coding parameters of each video codec to improve the overall video call quality of multi-channel video communication.

[0037] like figure 1 As shown, a multi-channel video communication method includes the following steps:

[0038]Step S102, establishing a candidate video coding parameter table. The video coding parameter table is a relationship table between video coding parameters and video rate distortion characteristics. When a certain set of video coding parameters is selected to encode the original video data, the obtained bit rate and decoded video distortion will be the same as the set of video coding parameters....

Abstract

A method for multichannel video communication comprises the following steps of (1) detecting network condition information and more than two long-distance client attributes, and setting up video communication connection; (2) choosing video coding parameters corresponding to each long-distance client according to the network condition information and each long-distance client attribute; (3) separately coding video data according to the video coding parameters; (4) transmitting the separately coded video data to each long-distance client. In the method for the multichannel video communication, the step two ensures that the coded video data received by each long-distance client is in conformity with the network bandwidth and the equipment attribute, thereby improving the quality of the multichannel communications. In addition, a multichannel video communication system is further provided.

Description

【Technical field】 [0001] The invention relates to the technical field of computer networks, in particular to a multi-channel video communication method and system in a computer network. 【Background technique】 [0002] The development of Internet technology has greatly changed people's work and life. Among them, video communication technology enables people who are thousands of miles away to have a face-to-face communication experience. Therefore, video communication technology is widely used in video chat, video conference, and online games. [0003] Due to the large amount of raw video data that needs to be processed in video communication, it is necessary to perform video encoding on the raw video data before transmission. By setting encoding parameters such as resolution, frame rate, and bit rate for the video encoder, a video code that meets specific requirements is generated. flow. At the receiving terminal, the decoded video image can be obtained by decoding the vid...
