Abstract

Many companies are developing products about MPEG-4 video standard,Digital Video Recorder(DVR) is the most.In order to cut dowm development time,applying the special video CODE chip AT2042,which realizes function for digital video recorder based on embedded Linux operating system.The system has some functions such as play,pause,recorder and so on.The practical testing results of the system are given,the coding/decoding for video data and video standard such as MPEG-4/MPEG-2/MPEG-1 H.263.
