Focus on the problem that TI’s dedicated video processor TMS320DM8148 cannot directly collect video data from HDMI interface, this paper presents a video coding system based on H.264.The system used DSP+FPGA architecture, FPGA is responsible for collecting video data of HDMI interface and caching. And then send to DM8148 through GPMC, DM8148 completes video encoding and decoding through the interaction of internal modules. The results show that video is displayed clearly and smoothly, without distortion or error. It successfully realizes the collection of the video data of HDMI interface obtained with DM8148.
