    摘要： An input digital video signal representing a series of input frames with at least some of the input frames each having a first picture portion having a first acquisition characteristic (such as 60 Hz, 2:1) and a second picture portion having a second acquisition characteristic (such as 30 Hz, 1:1) is processed to produce an output video signal representing a series of output frames having generally the same acquisition characteristic (such as 24 Hz, 1:1). The method comprises the steps of distinguishing between the first and second picture portions in the input frames (for example by determining the difference between input fields (a.sub.1, a.sub.2 ; a.sub.3, a.sub.4 ; . . . ) of a pair, or by detecting a key signal accompanying the input video signal) and processing the first and second picture portions differently to produce the output frames.

    摘要： A motion compensation technique for color video signals involves deriving at least one principal component from the video signals by means of a hotelling transform circuit and a matrix, and applying motion compensation to an interpolator (or to a compressor/decompressor) on the basis of the derived principal component. The technique avoids the need to provide three separate compensation circuits for each of the video signals while ensuring that optimum use is made of the color information in the video signals.

    摘要： A method of processing a digital video signal to derive motion vectors representing motion between successive fields or frames of the video signal comprises compares the contents of blocks of pixels in a first field or frame of the video signal with the contents of a plurality of blocks of pixels in a following field or frame, and produces for each block in the first field or frame a correlation surface representing the difference between the contents so compared in the two fields or frames. A grown correlation surface is produced for each block in the first field or frame by weighting the correlation surfaces for that block and a plurality of other blocks in an area around that block so as to accentuate features of the correlation surface for that block relative to those for the other blocks, and summing the weighted correlation surfaces. From each grown correlation surface, a motion vector is derived representing the motion of the content of the corresponding block between the two frames in dependence upon a minimum difference value represented by the grown correlation surface.
