  • Patent number: 4679038
    Abstract: Pixel representations for each of a plurality of superimposed (or splitscreen) display portions are accumulated in a band buffer prior to being transferred to the display. The actual pixel representations are made available to the band buffer from an image memory, with addresses provided by a display list memory. This system minimizes the need for buffering and high speed storage to service the video, by addressing first the display list memory, then in turn using the content of the display list memory to address the image storage, and then in turn using the content of the image storage as the actual pixel representations for accumulation in the band buffer. Two band buffers operate alternatively. The current band buffer is feeding a band of pixel representations to the video shift register while the next band buffer is accumulating the pixel representations of the subsequent video display band. The band buffer accumulates actual pixel representations equivalent to the related band of the display.
