Method and system of displaying video simultaneously

Abstract

The invention discloses a method of displaying video simultaneously. The method comprises the steps that a synchronization master and at least one synchronization slave lead a displaying package, wherein the displaying package is packaged with a video file list, at least one video file and a mark identity (ID) corresponding to the video file, the synchronization master displays the video file according to the video file list, sends the mark ID corresponding to the displayed video file to at least one synchronization slave, and sends displayed video frame information to the synchronization slave in real time, and the synchronization slave receives the mark ID sent by the synchronization master in real time and searches the video file in the displaying package according to the mark ID, if the corresponding video file is searched, the video file is displayed according to the video frame information, and if the corresponding video file is not searched, the present video file is displayed continuously. The method enables the videos of the synchronization master and the synchronization slave to be displayed simultaneously, is accurate to the video frame, and achieves shocking effect of the video.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and system for synchronous video playback. Background technique [0002] With the development of information technology, people's requirements for multimedia advertising systems are constantly increasing, especially in shopping malls, promotional meetings, exhibitions, brand stores and other occasions. Multiple video advertisement players can realize synchronous video playback. [0003] At present, the methods for realizing synchronous playback of multimedia advertising machines on the market are mainly divided into two types: hardware implementation and software implementation. Display the signal output by a player box, so as to achieve the effect of synchronization. The software implementation method currently used in the market is that multiple advertising machines are connected to the same server through the network, and the server initiates synchronization con...

AI Technical Summary

Problems solved by technology

[0004] The implementation method of synchronous playback hardware is relatively simple, but the flexibility is not very good. The display signal output from the same advertising player box requires the display resolution and other parameters of each display to be consistent, and it is easy to cause interference signals that will affect the display effect of the display screen. Commonly used The synchronization time command initiated by the server starts playing time together according to the time tag. When playing a long video file, it cannot be truly synchronized. It can only be synchronized when the file starts to play. After a period of time, due to various video players The speed cannot be the same. For example, the video playback speed is affected by the decoder, disk reading speed, etc., and it is difficult to achieve the same speed during the playback process, so there is no way to synchronize
