Document Type and Number:
WIPO Patent Application WO/2021/238653
Kind Code:
A1
Abstract:
The present disclosure relates to a broadcast directing method, apparatus and system, and a computer-storable medium, which relate to the technical field of computers. The broadcast directing method comprises: acquiring a reference video stream from a reference camera position; performing event recognition on the reference video stream to obtain at least one reference event frame interval, wherein each reference event frame interval corresponds to a unique event, and each reference event frame interval comprises frame identifiers of a plurality of successive images in which the same event occurs; determining a local sequence of each reference event frame interval according to a correlation between an event and a camera position identifier, wherein the local sequence comprises a camera position identifier of each frame of image of a video to be broadcast which corresponds to the reference event frame interval, and a frame identifier corresponding to the camera position identifier; generating a broadcast directing sequence according to local sequences; and generating a broadcast-directed video according to the broadcast directing sequence and video streams of corresponding camera positions. According to the present disclosure, labor costs are reduced, and the real-time performance and accuracy of broadcast directing are improved.
