Problems solved by technology

[0005] If the server no longer handles the task of multi-picture synthesis, the participating terminals need to encode and decode multiple video streams by themselves. However, this new participating terminal cannot adopt the same method as the traditional participating terminal (supporting SIP (SessionInitiation Protocol, Session Initiation Protocol). ) or H.323 protocol) for data interaction, which leads to poor compatibility of the video conferencing machine

Abstract

The present invention provides a video conference data transmission method and a video conference data transmission system, wherein the video conference data transmission method includes: accessing the first type of terminal equipment for video conference, and receiving the first type of terminal equipment sending resolution request; use audio and video conference coding technology to generate multiple channels of single video stream data, and send the corresponding channel of single video stream data to the first type of terminal device according to the resolution request. Through the technical scheme of the invention, the compatibility of the video conferencing system with the terminal equipment participating in the conference is improved, and the concurrency and flexibility of the cloud video scheme are promoted.

Description

technical field [0001] The present invention relates to the technical field of video conferencing, in particular to a method for transmitting video conferencing data and a system for transmitting video conferencing data. Background technique [0002] In order to provide a better user experience for the terminal users participating in the video conference, the server usually uses a multi-picture composition technology to synthesize the pictures uploaded by multiple participating terminals into a combined picture and then send it to the participating terminals at the receiving end. [0003] Although the end user's experience of participating in the meeting has been improved, it will lead to an increase in the calculation load of the server, which increases the cost of the server, and the capacity of the server is very limited, which cannot meet the needs of the ever-expanding scale and capacity of the video conference. [0004] In related technologies, the concept of exchange ...
