Abstract

The invention discloses a video data stream allocation method, device and system. The allocation system comprises a server and at least two terminals, wherein the at least two terminals are used for uploading media streams to the server; and the server is used for receiving the media streams from the terminals, matching corresponding media streams to be displayed for the at least two terminals, and returning the media streams to the displayed to corresponding terminals respectively. Through adoption of the video data stream allocation method, device and system, the technical problem of low transmission efficiency of the media streams in a video conference caused by the process of forwarding video streams of each terminal by a media controller or the server is solved.

Description

technical field [0001] The present invention relates to the application field of communication technology, in particular to a method, device and system for distributing video data streams. Background technique [0002] With the development of communication technology, various conveniences have been provided for people, such as shopping, eating, paying bills, etc., especially in the office field. From the era of telephone and fax, between companies, between companies and individuals, and between people Communication with people, in the video era, even if you are separated from two places, or even in a foreign country, as long as you agree on a time, two or more users will be able to hold a video conference through the network. [0003] The video stream transmission methods currently used in video conferencing mainly include: server forwarding mode and media control unit (Media Control Unit, referred to as MCU) transfer mode. Take a three-terminal video conference as an exampl...
