Embodiment Construction

[0055] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] Reference figure 1 , Shows a flowchart of Embodiment 1 of a method for synchronously playing videos on multiple terminals of the present invention, including:

[0057] Step 101: The network server sends the video file to each playback terminal;

[0058] In order to ensure that multiple playback terminals can display the same video screen, first, the video files that need to be played synchronously stored on the network server side need to be sent to each playback terminal. The network server and the playback terminal do not need to be connected through a distributor or a split screen, but the video signal is transmitted through the Internet.

[0059] Step 102: When the network server plays the video file, it sends th...

Abstract

The invention provides a multi-screen synchronized video playing method and system. The method of the invention comprises the following steps: a network server sends video files to each playing terminal; when the network server plays the video files, the network server sends the current play information to each playing terminal; and each playing terminal synchronously plays the video files on a local screen through positioning and calibration according to the received video files and current play information. The invention can reduce the cost of system resources and realize better video synchronizing effect.

Description

Technical field [0001] The present invention relates to the field of video technology, in particular to a method and system for synchronously playing multi-screen videos. Background technique [0002] The development of scientific and technological information has promoted the advancement of video technology. The screen display of video is widely used in various fields such as outdoor advertising, public transportation, publicity and exhibition. In some occasions, multiple display screens are required to display the same video at the same time, for example, the video playback of multiple display terminals in different azimuths in an exhibition hall. One of the most important technologies for multi-screen display is the need to keep the videos of multiple screens playing simultaneously. [0003] A common way of video synchronization is to use a splitter or a split screen to achieve synchronized video playback on multiple display terminals. Video splitter or screen splitter is a de...
