Technical field
The utility model relates to player, specifically a kind of can synchronously, asynchronous controlling play LED display.
Background technology
LED display is a kind of terminal equipment of electronic medium of modern public place, and controlling LED display is at present all with the control mode of computer control display screen, is synchronous control mode.If need not computer-controlled employing player form be asynchronous controlling mode, the method of synchronization can some real-time information can be play at any time on LED display, but it is large to there is volume, put that have must space, also have computer to hold the impact of susceptible viral and environment.The player volume of asynchronous controlling is little, stable performance, but can not play real-time information, and I has invented just for these problems the synchronous and asynchronous LED display that the various advantage of collection combines.
Utility model content
Primary and foremost purpose of the present utility model be to provide a kind of can synchronously, the LED display play of asynchronous controlling, realized by following proposal:
Can synchronously, asynchronous controlling play a LED display, comprising:
Processing unit, described processing unit, for reading played file, represents with digital signaling and processes;
The output of described processing unit is connected to field programmable gate array, and described field programmable gate array is used for can by the analog signal of LED player identification by described digital signal modulated one-tenth;
The input of described field programmable gate array is also connected with demodulation module, and described demodulation module can by the analog signal of LED player identification for the synchronizing signal of input being demodulated to.
Preferably, described played file stores in the memory unit, and described memory cell is SD card, SATA hard disk, the external memory storage connected by USB or the network memory connected by network.
Preferably, described processing unit is MIPS chip Sigma 8652.
Preferably, described field-programmable gate array is chip ALTERA EP4CE30.
Preferably, described demodulation module is chip is IT6613.
The utility model provide can synchronously, the LED display play of asynchronous controlling has synchronous broadcasting and the conversion of asynchronous play function, make both synchronously to play TV programme, also can automatically switch asynchronous local playing image program; When LED display asynchronous play, need not the video file format transformation play, original video file is play-overed, and press the high definition standard of 1080P, control the LED display that pixel reaches 1920 x1080 points, by the high definition standard of 1080P, realize video image file store and management and picture and text, sound broadcasting, ensure that the quality that video file is play and effect.
Accompanying drawing explanation
