Wireless remote LED display screen control transmission system

Abstract

The invention provides a system with wireless remote LED image transmission, which is composed of a user computer system, an image processing card, an internet, a server, a wireless internet, and a terminal LED screen, wherein the user computer system is connected with the image processing card which is connected with the server via the internet, the wireless network connects the terminal LED screen with the server. The system can realize the control of single host on a plurality of display screens, which builds a server website to provide LED screen terminal management and wireless network service to terminal user, and uses image compression algorism to realize the system structure of wireless remote LED screen image transmission.

Description

technical field [0001] The invention belongs to the technical field of LED screen image display, and in particular relates to a wireless remote control system structure and an image coding application method. Background technique [0002] There are many ways to control the LED display screen. One method is directly connected to the computer through the computer interface or local area network, and processed by the computer or corresponding hardware. The disadvantage of this method is that the distance between the LED screen and the control computer is limited. The distance of the line to transmit the image does not exceed 20 meters. Based on other systems such as infrared systems, radio systems and laser control systems, there are also control difficulties and distance restrictions as well as radio regulatory restrictions. In addition, this implementation method also requires a one-to-one implementation of the computer and the display screen. [0003] In order to overcome ...

Problems solved by technology

[0002] There are many ways to control the LED display screen. One method is directly connected to the computer through the computer interface or local area network, and processed by the computer or corresponding hardware. The disadvantage of this method is that the distance between the LED screen and the control computer is limited. The distance of the line transmission image is not more than 20 meters

Based on other systems such as infrared systems, radio systems and laser control systems, there are also control difficulties and distance restrictions as well as radio regulatory restrictions.

In addition, this implementation method also requires a one-to-one implementation of the computer and the display screen.

[0003] In order to overcome the distance limitation, another method can use wireless transmission methods such as GSM short message transmission. The amount of data transmitted in this method is also very small, so it cannot be realized in the field of image transmission. It is also impossible to transmit images through a wireless network (such as a GPRS network)
