    摘要: An encoder encodes a video signal formed of video frames, each including image blocks. The encoder includes a processing unit which calculates at least one high resolution reference image block on the basis of previously encoded image blocks by executing a super resolution algorithm to perform a local motion compensation; and a motion compensation unit which calculates on the basis of the calculated high resolution reference image block a temporal predictor which is subtracted from a current image block of the video signal. Together, the encoder and a corresponding decoder improve the signal quality of a video signal significantly.

    摘要: A series of decoded images is generated from a series of original images encoded by a first encoding technique following movement-compensated, predictive encoding, where a starting image of a group of successive original images that are to be encoded is defined by a second encoding technique following movement-compensated, temporally filtered partial band encoding based on a determined encoding property of a decoded image of the group of images that are to be encoded, the decoded image is used for generating an output image having a low resolution level, before the images are encoded. At least one output image is generated on each level of resolution from the successive original images of the group of from at least one decoded image during image encoding. The decoded images are provided only with a reduced quality while the reconstituted images are of great quality.
