Medium broadcaster with synchronizing function

Abstract

The invention relates to a media player, especially relating to a media player with a synchronizer, used to circularly play video advertisements. It comprises sound-video decoder unit, picture displaying and sound outputting unit, power supplying and timing control unit, and CF card and card seat unit; the synchronizer is composed of sound-video decoding unit of host machine, synchronous RF transmitting unit, synchronous RF receiving unit, and sound-video decoding unit of slave machine. The invention uses CF card as storage medium, where the CF card can be circularly used, thus able to eliminate one-off loss of DVD discs and reducing maintenance cost. The circuit of the synchronizer arranged in the invention is simply designed, eliminating MCU control unit and two infrared emission units in the existing techniques, thus making the cost low and convenient to produce and maintain. The synchronizer does not send out a synchronizing signal until the advertisement playing program reaches the synchronous RF transmitting unit, which assures the integrity of advertisement program.

Description

technical field [0001] The invention relates to a media player, in particular to a media player with a synchronizing device for looping video advertisements. Background technique [0002] At present, the independent media player devices used in public places generally use the built-in DVD drive to play the content of the disc as the signal source and supply it to the LCD display, as shown in Figure 1. The media player adopting this method is easy to cause the loss problem of the DVD optical drive after being used for a long time, and in the occasion where the advertisement content needs to be replaced frequently, it will cause a large amount of loss of the one-time burnable DVD disc. [0003] In the current independent media player, in order to solve the problem of keeping the program content of multiple media players placed in a small environment consistent or synchronized, one of the media players is generally used as the host that can trans...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to mainly adopt built-in DVD as the audio and video decoding unit for the LCD liquid crystal multimedia players in the mainstream market at present, but the DVD optical drive has the shortcoming of easy wear and tear, and DVD recording disc is a kind of consumable material again, so cause The problem of high operating costs of media players
