摘要
设计了基于DM8148处理器的高清视频处理系统,介绍了各硬件模块的设计以及系统应用程序的编写。系统的采集模块将采集到的高清视频数据送入高清视频处理子系统。视频处理模块对视频进行去隔行、尺寸调节、添加OSD和H.264编解码算法处理,处理过的视频流经HDMI接口输出。
This article designs a high-definition video processing system based on DM8148 and describes theeach hardware module and system application programming. The video capturing module sends captured data intoHDYPSS, and then deinterlacing, size adjustment, OSD addition and H. 264 codec processing are applied to thevideo stream in the video processing module. The processed video stream is output via the HDMI interface.
