  • Method and apparatus for motion estimation for digital video encoding
    Patent number: 6496538
    Abstract: A method for determining motion estimation in a set of video frames including the comparing of a first macroblock from a video frame in the set of video frames to a second macroblock in a reference video frame to determine a differential value. Then, the differential value is compared to a comparison value. If the differential value is not smaller than the comparison value, then the differential value is compared to a minimal differential value. If the differential value is less than or equal to the minimal differential value, then the differential value is stored as the minimum differential value. An apparatus for performing the method.
