摘　　要：针对视频信号制式多、数据量大、特别是对时序要求严格的特点,设计并实现了一种基于"FPGA+SAA7111A"结构的嵌入式视频播放器。利用现场可编程门阵列(FPGA)的可重构特性,采用一片FPGA同时完成视频解码芯片的配置、图像信号的采集与TFT LCD的驱动控制。经过测试,该设计能够满足PAL/NTSC两种制式彩色复合视频信号的需要,实现较高画面质量的视频播放。An embedded video player based on ＂FPGA ＋ SAA7111A＂ structure is designed and implemented to solve the problems of video＇s much format, high speed and strict synchronization. The functions of configuration of video decoder chip, video acquisition and the driving of TFT LCD are realized based on one chip of FPGA for its properties of filed programmable ability. According to the test, the design can process the video signals of PAL/NTSC formats and can play high-quality video.
