Problems solved by technology

[0003] However, since it takes a certain amount of processing time for the video stream to be played from the video source server to the user end, the time when the video source server sends the video stream may not be synchronized with the time when the user end plays the video stream. playback delay
Moreover, since different relay servers have different processing times for the live video stream, in the live broadcast system of the same video source server, the playback delays of different clients may be different, resulting in different video streams played by different clients at the same time point. Unable to synchronize, affecting the live broadcast effect
[0004] Therefore, there is an urgent need for a video synchronization method to solve the problem that the live video streams played by different clients cannot be synchronized

Embodiment Construction

[0034] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] Before explaining the embodiments of the present invention in detail, the application scenarios of the embodiments of the present invention will be introduced. The method provided by the embodiment of the present invention is applied to a live video system, see Figure 1A The video live broadcast system may include a video source server 10 and multiple client terminals 20. The video source server 10 may obtain live video collected by video capture devices such as cameras, and send live video streams to multiple client terminals 20. 20 can play the live video stream. Wherein, the client 20 can be a PC (Personal Computer, personal computer), mobile phone, tablet computer, etc., and the client 20 can play the live video stream through a pl...

Abstract

The present invention discloses a video synchronization method and device, belonging to the communication technology field. The method comprises the steps that: in a process of sending a live video stream to a plurality of user terminals, adding a time stamp on an assigned video frame of the live video stream; obtaining sending delays of the user terminals for each user terminal in the user terminals, wherein the sending delays are determined and obtained according to response information sent by the user terminals according to the received time stamp on the assigned video frame; and accordingto the sending delays of the user terminals, performing delay sending of the live video stream to the user terminals to perform synchronization of the live video stream played by the user terminals.The problem is solved that live video streams played by different user terminals cannot be synchronized, and a live effect is improved.

Description

Technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a video synchronization method and device. Background technique [0002] In a live video system, the video source server can obtain live video collected by video capture devices such as cameras, and send the live video stream to different clients, or rebroadcast via different rebroadcast servers, and indirectly send to different clients The live video stream allows different user terminals to play the live video stream, so that different users can watch the live video. [0003] However, since the video stream is sent from the video source server to the user side, it takes a certain amount of processing time. Therefore, the time when the video source server sends the video stream may not be synchronized with the time when the user side plays the video stream. Playback delay. Moreover, because different rebroadcast servers have different processing...
