Abstract

The invention relates to a cluster-type play control system and method as well as a management center of the system. The system comprises a management center and a media paly terminal, wherein the management center is used for manufacturing and generating a program list and providing media and fingerprints of the media which correspond to the program list, and the content of the list program comprises the fingerprints of the media; and the media play terminal is used for acquiring the program list, the media and the media fingerprints which belong to the terminal, calculating the fingerprints of the acquired media and comparing the calculated media fingerprints, the fingerprints of the acquired media and the media fingers contained in the program list, so that the correctness verification of downloaded files is realized. According to the cluster-type play control system and the method as well as the management center of the system, the program list and the media fingerprints are generated, and the program list comprises the fingerprints of the media, so that the correctness of the media in the whole centralized announcement process can be guaranteed to an extremely large extent.

Description

technical field [0001] The present invention relates to the technical field of display control, in particular to a clustered playback control system, a clustered playback control method, and a management center suitable for application in the clustered playback control system and method. Background technique [0002] Existing LED (Light Emitting Diode, light-emitting diode) display screens are used as media playback terminals, and can be divided into synchronous control LED display screens and asynchronous control LED display screens according to different control methods. Among them, the synchronous control LED display usually mainly includes a computer, a sending card and an LED screen. The screen will not be able to continue playing media. The asynchronous control LED screen mainly includes the asynchronous control card (an embedded control card with an ARM processor) and the LED screen body. The asynchronous control card integrates the functions of the computer and the ...
