Title:
VIDEO SYNCHRONIZATION METHOD, SERVER END VIDEO SYNCHRONIZATION DEVICE, AND CLIENT VIDEO SYNCHRONIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/133109
Kind Code:
A1
Abstract:
A video synchronization method, a server end video synchronization device, and a client video synchronization device. The server end video synchronization method comprises: parsing a key frame in a video; generating a video synchronous broadcast; and sending the video synchronous broadcast on a pre-determined number of video frames before the key frame. The client video synchronization method comprises: receiving a video synchronous broadcast, the video synchronous broadcast comprising key frame information; on the basis of the video synchronous broadcast, determining whether the client and the server side that sent the video synchronous broadcast are located on the same frame; and if the client and the device that sent the video synchronous broadcast are not located on the same frame, synchronizing same to the key frame. Firstly, a time checking function is added for a client and server, thereby solving the problem of delay when sending an instruction between the client and server; secondly, a video synchronous broadcast is sent on a key frame position by means of obtaining the key frame time of a video, thus solving the problems of player search inaccuracy and synchronization latency, and implementing synchronous playback.
