摘要
目前,市场上大部分的视频采集都是普清的,针对嵌入式高清视频图像采集与显示的应用要求,笔者提出了一种基于FPGA的HDMI数字高清视频采集与显示的方法。该系统采用FPGA作为主控制器,通过硬件描述语言编程设计了系统前端视频采集模块、高速视频传输模块、高清视频显示模块,有效实现了视频的实时采集、传输与显示。通过实验验证,系统可对60 fps、24 bit、1 080 p的视频图像进行有效处理,证明了系统软硬件设计的合理性和优越性。
At present,most of the video capture on the market is general-purpose.According to the application requirements of the acquisition and display of embedded HD video images,the author presents a method of HDMI digital high-definition video capture and display based on FPGA.The system uses FPGA as the main controller,and designs the front-end video capture module,high-speed video transmission module and high-definition video display module through hardware description language programming,effectively realizes the real-time video capture,transmission and display.Through the experimental verification,the system can provide effective processing for video images of 60 fps,24 bit and 1080 p,which proves the rationality and superiority of system hardware and software design.
