摘要
视频处理芯片是嵌入式视频系统的核心部件之一,具有视频信号采集、编码、解码、输出等功能。以数字视频监控系统为背景,通过为多功能视频处理芯片TW2824开发Linux下的驱动程序对视频处理和驱动技术进行了研究,从而有效的实现了对视频输入输出与控制、视频移动侦测、在屏显示等功能。
Video controller chip,which is one of the important component of video embedded systems,plays an important role in video signal acquisition,decoding,encoding,output and other important functions.Taking new type digital monitoring system as the backdrop,the driver technology of video controller chip is studied by developing the driver of TW2824.Though the research of video controller chip's driver,video input and output control,video motion detection and on screen display system are realized.
