  • Video processor using shared memory space
    Patent number: 6529249
    Abstract: Memory requirements in a video processor and display system are reduced by storing in memory processed video signals for a plurality of regions of a picture, processing video signals for additional regions of a picture while stored video signals are retrieved in controlling a display, and then storing the newly processed video signals in the memory space occupied by the retrieved video signals. An entire reconstructed frame of image signals is not needed in order to begin the display of the same frame, certain regions of the frame can be displayed while other regions are still being reconstructed. Overwrite protection is provided for stored image signals until the stored image signals are retrieved for image display.
