Conference video marking system based on sound detection

Abstract

The invention provides a conference video marking system based on a sound detection. The system comprises a container block head, which is used for storing audio and video data position information ofthe same participating member in the conference; N container blocks, which are used for storing audio and video data of each participating member in the conference; a resolution scaling module, whichis used for scaling the video resolution by decoding and encoding the video data; storing the audio and video data information in the conference video to the container block head, and storing the different audio and video data of each participating member in the conference video into the corresponding container block. According to the conference video marking system based on sound detection, theplaying operation is simple, and the picture of the speaking member needing to be viewed can be rapidly switched according to the label; the playing can be flexibly combined, the pictures of all the speakers are extracted at the same time, and the speaking content of all members is rapidly compared; a simple file format is defined, the data is saved by using blocks, and the data extraction is simple and flexible.

Description

technical field [0001] The invention relates to the technical field of audio and video processing, in particular to a conference recording marking system based on sound detection. Background technique [0002] The existing conference video generation mode is generally to generate a video file for each conference member, and its playback mode is to combine each video file for playback. Although the playback is flexible, the operation is too cumbersome, as follows figure 1 . Or directly record the mixed-screen image of the entire meeting, and its playback mode is to play the file of the entire mixed-screen image. The operation is simple and clear, but the playback is relatively simple and not flexible enough, as follows figure 2 . Now I hope to find a solution that can flexibly play the entire meeting process, which can freely and quickly switch to the screen of the speaking member, or all members can play at the same time at a time point, and quickly compare the speech con...
