<p>IMAGE STORAGE USING SEPARATELY SCANNED WIDEBAND AND NARROWBAND VARIABLES Computer main memory is used for storing relatively densely sampled wideband video information concerning a television display and for storing relatively sparsely sampled narrowband video information concerning the same television display. The relatively densely sampled wideband video information is read out in substantially real time from computer main memory during line trace intervals in the television display. The relatively sparsely sampled narrowband video information is read out of computer main memory in advanced and compressed time during selected line retrace intervals in the television display. The wideband video information may be luminance information; and the narrowband video information chrominance information.</p> |
