Abstract
An apparatus, for use in a motion-compensated video signal encoder, for determining a predicted current frame based on a current frame and a previous frame of a digital video signal, including: a unit for selecting a number of pixels from the pixels contained in the previous frame; a unit for detecting a first set of motion vectors between the current and the previous frames, each of the first set of motion vectors representing a motion for each of the selected pixels; a unit for producing a second set of motion vectors for all of the pixels contained in the current frame by using the first set of motion vectors; and a unit for assigning the value of each of the pixels in the previous frame, which corresponds to one of the pixels in the current frame through one of the second set of motion vectors, as the value of the one of the pixels in the current frame.
