In this paper, a 3-channel 8-bit analog HDTV (high definition television) image sampling and recording system is described in detail. It can grab images up to 1024/spl times/1024 pixels from a motion picture sequence (in the case of 2:1 interlaced scanning; 25 frames per second) with low error bit rate. Finally, the test result is presented.
