Abstract

The invention discloses a video conference implementation method, a multi-point control unit, equipment and a readable storage medium. The method comprises the following steps: acquiring network quality parameters of each conference terminal in a video conference and processing capability information of FEC (Forward Error Correction); determining a coding redundancy level corresponding to each conference terminal according to the network quality parameter and the FEC processing capability information; determining a target coding redundancy level according to the coding redundancy level corresponding to each conference terminal, and sending the target coding redundancy level to the source conference terminal, so that the source conference terminal performs FEC coding on the video stream according to the target coding redundancy level; obtaining a video stream after FEC coding by the source conference terminal; and according to the coding redundancy level corresponding to each conference terminal, sending the video stream after FEC coding to each conference terminal. By implementing the application, the FEC coding resource and bandwidth of the multi-point control unit can be greatly released, and the multi-point control unit can meet the FEC requirements of a large number of conference terminals.

Description

technical field [0001] The present application relates to the technical field of video conferences, and in particular, to a video conference implementation method, a multipoint control unit, a device, and a readable storage medium. Background technique [0002] With the rapid development of the mobile Internet, video conferencing related services have grown explosively. The number of conference terminals and the number of Internet devices connected to the video conference are also increasing, which leads to a considerable test of the carrying capacity of the network channel, and various kinds of audio and video inevitably appear in the network transmission. Problems, such as network data packet loss, may cause intermittent sound, video blur, freeze, etc., which reduces the user experience. [0003] Using Forward Error Correction (FEC) is one of the main methods to solve the above problems. However, in a large-scale conference scenario, the coding resources of the multi-con...
