    摘要： A video signal shuffling device forms a segment with blocks having a given offset value in horizontal and vertical directions from a given starting point uniquely determined on the screen, the offset value being identical in every region. The segment is formed in a unit of one frame or two frames. The shuffling device divides one frame comprising blocks into a plurality of regions. A coding device determines a final priority as well as a final quantizer thereby quantizing a segment and providing the segment with a variable-length-coding based on a first priority, coding-quantity obtained from a plurality of quantizers, second priority and a quantizer. A coding device and its decoder, the coding device carries out a hierarchical coding by only a motion vector in a compressed stream at a lower resolution side and by agreeing a motion detected and a DCT block size with a size on the screen.

    摘要： The present invention includes a motion vector detector for detecting motion vectors using a first image signal of high resolution; a resolution reducer for creating a second image signal of low resolution from the first image signal; an image signal interpolater for interpolating the second image signal so that it has the same number of pixels as the first image signal, thereby creating an interpolated signal; a differentiator for determining a differential between the first image signal and the interpolated signal; and an encoder for using the motion vectors to high-efficiency-encode the differential signal. Thus, by encoding two types of image signals of different resolutions, the present invention improves the accuracy of the motion vectors during the encoding of the high-resolution signal and reduces the rate after encoding due to the encoding of the differential signal.

    摘要： A video signal layering-encoding system according to the present invention has at least either a frequency distribution unit to judge a frequency distribution in an input video signal or a motion judgment unit to judge the motion of an input video signal. With this, encoding quantity control according to the characteristics of the input video signal can be performed between layers. Also, with selection of encode modes and sharing of a motion vector, the encoded data of a bidirectionally predicted frame can be reduced and the encoding efficiency of a high resolution signal can be increased. A digitial broadcast decoding system according to the present invention can readily display a plurality of broadcasting programs on different channels onto a small screen within a main screen when digital broadcasts are received, by a decoding method in which processing is easy, structurally simple circuitry, and software. In a digital broadcasting signal storage according to the present invention, by thinning out DCT coefficients to reduce the quantity of data to be stored or to slow down the storing speed of requisite data and by addition of a video signal decoding section and video signal encoding section for encoding video signals again, the video signal format in a storage medium can be fixed as a single format.
