ABSTRACT:
Computer main memory is used for storing relatively densely sampled luminance detail information concerning a television display and for storing relatively sparsely sampled narrowband color-component information concerning the same television display. The relatively densely sampled luminance detail 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 color-component information is read out of computer main memory in advanced and compressed time during selected line retrace intervals in the television display.
