  • Method and apparatus for video processing that includes sub-picture scaling
    Patent number: 6678006
    Abstract: A method and apparatus for processing DVD video data and sub-picture data is accomplished by storing a line of DVD video data and at least a partially decoded portion of DVD sub-picture data. The partially decoded DVD sub-picture data is still in an encoded format, which may be two bits per pixel, but line information has been decoded from the DVD subpicture data stream. Once stored, the DVD video data is retrieved from the memory and scaled to produce scaled video data. Similarly, the partially decoded sub-picture data is retrieved from memory, further decoded, and scaled to produce scaled sub-picture data. The scaled video data is blended with the scaled sub-picture data to produce a video output.
