In this embodiment, the video collection end includes multiple camera modules, and the multiple camera modules are respectively installed at different angles of the live broadcasting scene to collect multiple shooting videos from multiple perspectives of the shooting scene. For example, the camera module may be a camera. The video acquisition terminal also includes a video processing module for summarizing and processing the captured videos of each camera. The video processing module packs the multiple captured videos to generate a video code stream, and adds a descriptor to the video code stream.

Wherein, the video processing module may be a graphics processing device with a processor, such as a data server and a computer.

It can be understood that when multiple video data in the playback interface of the video playback terminal are to be played simultaneously, a descriptor needs to be added to the video code stream sent by the video collection terminal to describe the number of videos contained in the current program and how to Find these videos. For example, multiple video data may be numbered respectively to facilitate counting the number of video data and distinguishing each video data, or different identification information may be added to multiple video data for distinguishing.

Further, the video playback terminal receives the video code stream sent by the video collection terminal, and can also determine the number of videos in the current video code stream through the descriptor in the video code stream, and then the video playback terminal according to A corresponding number of playback windows is created for the determined number of videos and displayed on the playback interface, and each playback window is used to correspondingly play a captured video captured by a camera module.
