WIPO Patent Application WO/2020/238973

A1

The present invention relates to the field of remote video pushing, and with respect to the problem that existing pushing methods are not applicable to the teaching field, the present invention proposes an automatic detection and real-time pushing method for a multi-channel audio/video, the method comprising the following steps: A, selectively pushing an acquired multi-channel audio/video, the multi-channel audio/video comprising one default channel and at least one non-default channel, pushing the default channel by default; B, detecting in real time a human-computer interaction event in a source terminal of the default channel during recording and recording a corresponding human-computer interaction time point, and calculating a default channel switching-out time point and a default channel switching-in time point according to the human-computer interaction time point; and C, selecting, according to the default channel switching-out time point and the default channel switching-in time point, a video stream of an appropriate channel for pushing. Thus, by determining the state of a video by means of human-computer interaction and performing a corresponding pushing switch, the present invention is applicable to real-time remote teaching.
