Abstract:
A method of encoding a video signal comprising a series of pictures (f1,2,3, . . . ) in a motion-compensated encoder (3), said method comprising the steps of:receiving (30) the series of pictures (f1,2,3, . . . ); and estimating (31) motion vectors (m) in the series of pictures (f1,2,3, . . . ) with sub-resolution accuracy, making a choice (39) between generating and supplying a motion-compensated encoded video signal (I, B, P) and generating and supplying a higher-resolution picture (IH) having a higher resolution than the pictures (f1,2,3, . . . ) of the series, if the motion-compensated encoded video signal is generated, forming (38) the motion-compensated encoded video signal (I, B, P) by means of a picture memory (33), and if the higher-resolution picture (IH) is generated, forming (38) the higher-resolution picture (IH) from the series of pictures (f1,2,3, . . . ) and the motion vectors (m) by means of the picture memory (33).
