Description

Video switching method, device, system and storage medium

Technical field

The present disclosure relates to the field of communications, and relates to a video switching method, apparatus, system, and storage medium.

Background technique

In the multi-party video conference process, both the voice excitation mode and the chairman/director control mode have a venue as a broadcast source. When the terminal outputs the media stream, all the participating terminals except the terminal will watch the video image of the broadcast source terminal. When there are more than three terminals participating in the conference in the video conference, the broadcast source switching caused by the voice excitation or the conference control during the conference may cause the video of the terminal watching the broadcast source to switch.

The current video conference picture mode is divided into two modes: single picture and multiple picture. In single-screen mode, all sites can only see video images of one site, and cannot view video images of other sites. In the multi-picture mode, each site can see a preset multi-screen layout. Different sites display different sites. After being coded by the Multipoint Control Unit (MCU), they are sent to the terminals participating in the conference.

In the single-picture mode, when the image displayed on the terminal that views the broadcast source needs to be switched to the image of the current new broadcast source terminal in the video conference, the video fast update command (VCU) and the video freeze command (VCF) letter are usually used. Let the image on the terminal of the broadcast source be frozen by the VCF, stop transmitting the video code stream to the terminal watching the broadcast source, and send the VCU signaling to the new broadcast source terminal, when the MCU receives the I sent by the new broadcast source terminal. After the frame video stream is sent to the terminal watching the broadcast source. After receiving the new video media stream, the terminal watching the broadcast source switches the original broadcast source image that has been frozen on the display to the new broadcast source video image for playback.

The multi-picture mode is basically the same as the previous single-picture processing flow. The difference is that the frozen is no longer the terminal that watches the broadcast source, but the wide-area synthesis unit in the video conferencing system. The sub-picture image where the source video is broadcasted, so now the video switching of each video manufacturer in the case of single picture or multi-picture is a sudden switch from one frozen video picture to another new video image, which is not very good in user experience. .

In view of the low user experience in video conferencing image switching in the related art, there is currently no effective solution.
