Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] The flow chart of the method schematic diagram for a kind of multi-screen synchronous broadcasting of the present invention, as figure 1 As shown, the method includes:

[0039] Step 101: After any broadcast controller in the network is started, send an instruction requesting synchronization to all broadcast controllers on the network; each broadcast controller waits for the synchronization server to send a synchronization instruction to perform synchronization;

[0040] After each broadcast controller in the network is started, a thread is established to wait for synchronization and send a request synchronization command, and send a request synchronization command to all broadcast controllers on the network while waiting for synchronization, so as to reques...

Abstract

The embodiment of the invention discloses a multi-screen synchronization play method and device and belongs to the field of network communication. The method includes: sending a synchronization-request instruction to all of play controllers in a network after any of the play controller is started; if no synchronization server is available in the network, selecting a main play controller as the synchronization server from the play controllers; the synchronization server sending broadcast every one period and the rest reception play controllers receiving the broadcast; comparing information in the received broadcast with a broadcast state and sending the synchronization request instruction to the synchronization server if synchronization is needed; and the synchronization server sending the synchronization instruction to the broadcast controllers for synchronization operation. The multi-screen synchronization play device controls the play controllers in the network for multi-screen synchronization play and any play controller carries out synchronization operation as the synchronization server so that a synchronization display process with high reliability is provided, that is, any one display terminal is used as a control server, once the terminal has a problem, another terminal is used as the synchronization server at once.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for multi-screen synchronous playback. Background technique [0002] The development of scientific and technological information has promoted the progress of video technology, and video screen display is widely used in various fields such as outdoor advertising, public transportation, and publicity exhibitions. In some occasions, multiple display screens are required to simultaneously display video of the same screen, for example, video playback of multiple display terminals at different azimuths and angles in an exhibition hall. One of the most important technologies of multi-screen display is the need to keep the videos of multiple screens played synchronously. [0003] A common method of video synchronization is to use a splitter or a screen splitter to realize synchronous video playback of multiple display terminals. A video splitter or screen splitt...
