Problems solved by technology

[0002] LED display and LCD liquid crystal display are often used for advertising in public places. Generally, in different occasions and environments, depending on the intensity of light, LED display or LCD liquid crystal display will be used as the terminal display device. The LED display player is just It can control the image playback of the LED LCD display, but it cannot have the common playback function of the LED display or LCD liquid crystal display. The LCD liquid crystal display must be equipped with an LCD player, and the LED display can only be controlled by a computer. Therefore, When the two types of display screens are used at the same time, the same player cannot be used to play, and the player of the LCD liquid crystal display screen cannot play TV programs synchronously. In addition, in the application of LED display screens, one computer is used for one screen at present. The disadvantage is that the performance of the computer is unstable due to environmental conditions in various occasions (such as viruses, temperature, and computer operating systems, etc.), resulting in abnormal operation of the display screen, or only controlling some pixels during asynchronous playback. There are not many display screens, and the video file needs to be converted to record and broadcast, so after decoding, there is no sound of the original file, and only graphic effects can be played, without the sound of the original video file
Greatly destroys the effect of video file playback

Abstract

The invention relates to a synchronous and asynchronous playing player for LED and LCD display screens. The synchronous and asynchronous playing player comprises a processing unit, a signal switching module, a modulation module, a field-programmable gate array and a demodulation module. The synchronous and asynchronous playing player can provide image and sound playing functions for various brands of LED display screens and LCD light crystal display screens, thereby meeting the demand of using one player when the LED display screens and the LCD light crystal display screens are used together. The synchronous and asynchronous playing player has the function switching of synchronous playing and asynchronous playing, can synchronously play television programs and also can automatically switch asynchronous local playing image programs.

Description

technical field [0001] The invention relates to a player, in particular to a player for synchronous and asynchronous playback of LED and LCD display screens. Background technique [0002] LED display and LCD liquid crystal display are often used for advertising in public places. Generally, in different occasions and environments, depending on the intensity of light, LED display or LCD liquid crystal display will be used as the terminal display device. The LED display player is just It can control the image playback of the LED LCD display, but it cannot have the common playback function of the LED display or LCD liquid crystal display. The LCD liquid crystal display must be equipped with an LCD player, and the LED display can only be controlled by a computer. Therefore, When the two types of display screens are used at the same time, the same player cannot be used to play, and the player of the LCD liquid crystal display screen cannot play TV programs synchronously. In additi...
