  • Method and apparatus for video data compression using temporally adaptive motion interpolation
    Patent number: 5592226
    Abstract: In a system for compressing video data, temporally adaptive motion interpolation based upon temporal characteristics of human vision is used for establishing threshold levels relative to the degree of motion as a whole (global motion) between frames. The global motion between successive frames in a group of pictures (GOP) is measured to determine if the motion is less or greater than the established threshold levels for determining the designation of I, P, and B frames, spacing between I and P reference frames, and the number of bits used for each frame, and B frames therebetween.

  • Method and apparatus for video data compression using temporally adaptive motion interpolation
    Patent number: 5565920
    Abstract: In a system for compressing video data, the degree of global motion between a plurality of successive frames is determined for use in designating and spacing reference frames, relative to the global motion exceeding predetermined thresholds or levels of motion between certain ones of the frames.
