Abstract

The present invention relates to a video live broadcast synchronization method and system. After obtaining SEI enhancement information in the first video code stream sent by the broadcasting end and second time stamp information in the second video code stream, the first time stamp information is obtained from the SEI enhancement information. After the timestamp information, create a delayed task according to the first timestamp information and the second timestamp information, and determine the display time of the target information according to the first timestamp information and / or the delayed task. Based on this, the display time of the target information is determined through the first timestamp information and / or the delay task, which ensures that the display of the first video code stream and the second video code stream are synchronized, and that viewing users who join in the middle can see Target information at each historical moment. At the same time, the above effects can be achieved without adding additional supplementary information, reducing the pressure of streaming and maintaining the stability of the video streaming format.

Description

technical field [0001] The present invention relates to the technical field of live video, in particular to a method and system for synchronizing live video. Background technique [0002] With the development of information network technology, education has realized real-time or time-sharing distance education with the help of information network and related supporting technical equipment. Distance education mainly relies on the education platform to obtain and summarize teaching data, and each teaching terminal obtains teaching data through the teaching platform to complete the teaching, including video recording and broadcasting teaching or live video teaching. Relying on the development of cloud technology, distance education further reduces the setting limitations of education platforms and education terminals, including equipment limitations and user limitations. [0003] Live video teaching is an important part of distance education, especially in the application of c...
