LED playing system

Abstract

The invention provides an LED playing system which comprises a plurality of storage modules, a control module, a dynamic random storage module and an LED display module. The multiple storage modules are used for storing image files; the control module comprises a decoding unit, a control unit and an output unit, wherein the decoding unit is used for reading the image files from the multiple storage modules and decoding the image files into a plurality of frames of image data according to the format of the image files, and the control unit and the decoding unit are integrated through a system bus and used for receiving the decoded image data through the system bus, intercepting one frame of image data from the image data and outputting the frame of intercepted image data through the output unit; the dynamic random storage module is connected with the control module and used for receiving the image data output by the control module and caching the image data; the LED display module is connected with the output unit. By means of the LED playing system, chips are reasonably selected, the high-end control application requirement is met, and the aims of low cost and high performance are achieved on the basis of the existing product scheme.

Description

technical field [0001] The invention belongs to the technical field of LEDs, and relates to a playback system, in particular to an LED playback system. Background technique [0002] With the continuous vigorous development of the LED industry, people have high requirements on the quality and effect of LED advertising screens and LED advertising controllers. At present, some technical solutions on the market add a PCIE video processing card to multiple computers, the price is quite expensive, or a high-end ARM expands an FPGA, no matter from the perspective of cost or technical realization, they are not very satisfactory for LED. The needs of development cannot meet the high-end control applications, let alone achieve the goal of low cost and performance optimization. [0003] The following is the existing LED master control system: [0004] Existing LED main control system product solution 1: computer plus PCIE video processing card. Disadvantages: The system is complex a...
