摘要： 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.

摘要： 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.

摘要： A method and apparatus for branching among a plurality of data sequences received from a relatively high latency mass storage device. According to a preferred embodiment, a plurality of initial data sequences respectively representative of the initial portions of data sequences of the plurality of data sequences are retrieved from the mass storage device, wherein the length of each initial data sequence is selected in accordance with the latency of the mass storage device. The plurality of initial data sequences is stored in a storage device having a low latency relative to the mass storage device. There is determined a next data sequence to be retrieved from the mass storage device when a branch point is reached during a current data sequence. The initial data sequence corresponding to the next data sequence is retrieved from the low latency storage device while the high latency mass storage device locates the next data sequence.
