    摘要： A video signal recording apparatus including a switching device for receiving a digital progressive scan TV signal having a frame cycle which is 1/2 of the frame cycle of an interlaced scan TV signal and switching the progressive scan TV signal frame by frame alternately; a coding device for performing high-rate coding of data corresponding to one frame of the progressive scan TV signal to the same code amount as obtained by high-rate coding of data corresponding to one frame including two successive fields of an interlaced scan standard-definition TV signal; and a recording device for recording the data processed with the high-rate coding in the same number of tracks as the data corresponding to one frame of the interlaced scan standard-definition TV signal.

    摘要： A image signal processing apparatus and method for static image display are provided. Deformation at an edge of an image can be reduced by eliminating a temporal factor and vertical resolution can be retained even after data supplementation. In the process of compressing and decompressing interlace-scanned image data, one of two fields of a frame is selected by a field selector, image data is supplemented and reproduced based on the selected field data by a supplementor, and image data is outputted as a static image without deformation. As a result, more bits can be allocated for encoding by selecting and compressing one field data only and it leads to a higher quality image display. Furthermore, display deformation can be reduced by supplementing high frequency components as zero in the decompression processing.
