Embodiment Construction

[0031] Embodiments of the present invention provide a method and system for video communication and a device for video communication. When used for video communication, the flexibility of the system is improved. In order to make the purpose, technical solution and advantages of the present invention clearer, the following The present invention will be further described in detail with reference to the accompanying drawings and examples.

[0032] Referring to Fig. 1, it is a schematic diagram of a video conferencing system provided by an embodiment of the present invention. The first terminal 101, the second terminal 102, and the third terminal 103 respectively send their respective video streams and audio streams to the multipoint control unit 104, and the multipoint The control unit processes the received video stream and audio stream, and sends the processed audio stream and video stream to the first terminal 101 , the second terminal 102 and the third terminal 103 .

Abstract

This invention discloses a method and a system for video communication and a device used in it, in which, the method includes: identifying sub-frames received in a composite frame corresponding to audio flows, getting orientation information of the audio flows according to the positions of the sub-frames in the composite frame to send audio flows and related orientation information to the terminal, which processes the audio signals according to the information, thus the audio flow has orientation information.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for video communication and a device for video communication. Background technique [0002] With the widespread popularity of TV sets, users have higher and higher requirements for the size of TV screens. Some video communication systems even use projectors or video walls to display. At this time, if the picture is composed of at least two sub-pictures, different sub-picture The position of the speaker in the system will be quite different when the screen size requirement is low, and the sound position of the current multimedia communication system does not change correspondingly according to the change of the speaker's position, resulting in the position of the sound Messages and sprites do not match, thereby affecting the realism of the video communication. [0003] In the prior art, a video conferencing system includes equipment such as a multipoint ...
