摘要

传统的LED智能玻璃显示屏的控制系统需要以计算机作为视频源进行实时的视频输出，但在小规模场合中使用不够方便，因此本文设计了一种脱离实时视频源、便携的视频播放控制系统。该系统主要由视频输出单元和视频转发单元两部分组成，视频输出单元采用搭载操作系统的CPU+FPGA双核架构，CPU通过USB接口对U盘中视频数据进行读取，通过在CPU特定内置APP中进行地址映射图绘制，生成地址映射数据，并将视频数据和映射数据发送至FPGA，FPGA对视频数据重新排序，通过光纤发送至视频转发单元，视频转发单元接收并选取其中一部分视频数据，反Gamma校正后发送至驱动系统实现对显示屏上LED的控制，采用多个视频转发单元级联方式驱动大规模LED智能玻璃显示屏。此系统给产品应用带来了方便，具有更广泛的应用范围。

Abstract

The traditional LED intelligent glass display control system needs a computer as the video source for real-time video output

but it is not convenient to use in small-scale occasions

so this paper designs a portable video playing control system which is separated from the real-time video source. The system is mainly composed of two parts: video output unit and video forwarding unit. Video output unit adopts CPU + FPGA dual core architecture based on operating system. The CPU reads the video data in the USB disk through the USB interface

draws the address mapping map in the specific built-in APP of CPU

generates the address mapping data

and sends the video data and mapping data to FPGA. FPGA reorders the video data and sends it to the video forwarding unit through optical fiber. The video forwarding unit receives and selects part of the video data. After anti Gamma correction

it is sent to the driving system to realize the control of LED on the display screen. Multiple video forwarding units are used to drive large-scale LED intelligent glass display screen in cascade. This system brings convenience to product application and has a wider range of application.
