    摘要: In, for example, a motion compensated video standards converter wherein blocks in a first field or frame of a video signal are each compared with a plurality of blocks in the following field or frame of the video signal for deriving motion vectors representing the motion of the content of respective blocks between the first field or frame and the following field or frame, further motion vectors are selected for assignment to those of the blocks for which less than a predetermined plurality of good motion vectors are derived as a result of the comparison, by ranking all the good, non-stationary motion vectors derived for the field or frame in order of frequency of occurrence, and selecting those motion vectors which occur most frequently, unless they fall within a predetermined window of pixel motion of a motion vector already selected.

    摘要: An input digital video signal is converted to an output digital video signal having a different frame rate and a different number of pixel lines per frame. A first series of progressive scan format frames is formed from the input signal. Then a second series of frames is formed from the first series of frames using motion compensated temporal interpolation between successive frames of the first series in producing at least some of the frames of the second series so as to provide the difference in frame rate. Before or after the second series of frames is formed, vertical spatial interpolation is performed so as to provide the difference in the number of pixel lines per frame.
