Abstract

The invention relates to the technical field of telecommunications and discloses a multi-screen synchronization method and a playing system for the same local area network. The method includes the steps that a central server serving as a server side transmits at least one playing task to a plurality of intelligent terminals serving as client sides, wherein every intelligent terminal and the central server are in the same local area network, and the playing task comprises content to be played and content identification; the central server sends a playing instruction to every intelligent terminal in real time when the playing needs to be performed, wherein the playing instruction comprises the content identification of the content to be played; every intelligent terminal finds the content to be played according to the content identification and displays the content on a display screen of the intelligent terminal when intelligent terminal receives the play instruction. Compared with the prior art, the multi-screen synchronization method and the playing system for the same local area network achieve playing content synchronization of every intelligent terminal in the same local area network, and the number of the intelligent terminals can be unrestricted.

Description

technical field

[0001] The invention relates to the technical field of telecommunications, in particular to a multi-screen synchronization method and a playback system in the same local area network. Background technique

[0002] There are a large number of advertising screens on the subway and roadside. The advertising screens have built-in memory and playback modules, which can play static or dynamic images or play them in a loop according to pre-configuration. Each advertising screen exists independently of each other, and it is difficult to realize the synchronization of playback.

[0003] At present, one solution is to connect each advertising screen to the same local area network through a local area network. When the video needs to be played synchronously, the LAN server needs to push the video stream to each advertising screen in the LAN in real time for playback, that is, to realize the synchronization of each screen by pushing the video stream in real time.
