  • Method and apparatus for bit-shuffling video data
    Patent number: 6765625
    Abstract: “An image processing system, in which bit shuffling is done in order to maintain image quality, stores digitized video data bits stream in a conventional memory, such as a DRAM. The image processing system is suitable for widely-used image compression standards that integrate various algorithms into a compression system, such as the standards specified in the Digital Video Standard (the DV-SD standard, or “Blue Book”). The image processing system receives a number of blocks associated with a first video frame and stores these blocks in the DRAM. The image processing system receives and stores blocks associated with a second video frame in the DRAM. The image processing system, processes the blocks of the first video frame while storing the blocks of the second video fame.
