A multi-channel remote live video commentary method based on frame synchronization

Abstract

The present invention provides a multi-channel remote live video commentary method based on frame synchronization, comprising: a switching device is provided with a live audio and video stream buffer area; the switching device adds a timing sequence in front of the M live video frames, and Add a synchronization mark on the last timing frame of the timing sequence and send it to the cloud platform; the cloud platform sends it to each remote commentary terminal located in different locations; Write the corresponding live video frame number and send it to the cloud platform; the cloud platform sends it to the switching device; the switching device synthesizes it into a final live audio and video stream with commentary audio and video corresponding to a commentary terminal. The advantages are as follows: a method for synchronizing commentary in different places is realized, and for each commentator located in different geographic locations, the commentary terminal can be used to perform synchronous commentary on the same live program; and the commentary video information of the commentator can be obtained.

Description

technical field [0001] The invention belongs to the technical field of live video commentary, and in particular relates to a multi-channel remote live video commentary method based on frame synchronization.
