    摘要: Disclosed are a video signal recording apparatus for dividing digital video signal into blocks, transforming orthogonally, quantizing, coding in a variable length, and recording always in identical data quantity in a unit of specific number of blocks, and a video signal reproducing apparatus for decoding the recorded signal in variable length, quantizing inversely, transforming inversely and orthogonally, and reproducing the original digital video signal. The coding data in the specific number of blocks in the identical data quantity is divided in two code rows, the individual low frequency components are assigned to separate sync blocks, and high frequency components are also assigned to separate sync blocks, and recorded. When reproducing, if the sync block of high frequency components is wrong, it is possible to decode only with low frequency components, and the screen is reproduced at high fidelity to the reproducing speed at the time of high speed reproducing. By recording the position information indicating the boundary position between two code rows, or the concealment information showing the concealment state, even by variable length coding, the range of error concealment may be narrowed, and the effects of error may be minimized.

    摘要: A video data is accompanied or multiplexed with one or more flags indicating a relation between fields or frames of video data for transmission or recording. An interlace flag determines whether the video data is interlaced or not. A still image flag determines whether the video data carries a motion image, a field still image, or a frame still image. A frame change flag determines whether or not a given frame of the still image is identical to its previous frame. At least one of the three different flags is multiplexed with its relevant video data.

    摘要: When inputting moving image data into a personal computer for display or for recording on a recording medium, there often occur cases where processing cannot catch up with the input, resulting in interruption of the processing. Also, when performing conversion from an input digital signal having an arbitrary number of samples to an output digital signal having an arbitrary number of samples, prior art methods entail the possibility that the memory capacity and the amount of computation may become enormous. In view of this, according to the present invention, if the image processing cannot catch up with the input, the data is re-input for processing by utilizing information concerning the recorded position, the recorded time, or the time at which playback is to be performed; this achieves the same effect as processing continuous moving image data without interruption.

    摘要: The present invention includes methods and apparatus for attaining high speed coding and decoding. A first method decreases the number of memory access times by performing signal format conversion, orthogonal transform and continuous variable-length coding with predetermined small areas in a frame used as units. A second method omits orthogonal transform computation by using orthogonal transform coefficients to shorten the processing time. A third method uses additions and subtractions for orthogonal transform thereby decreasing the number of registers used and reducing the number of memory access times. The present invention further includes a decoding method for variable-length decoding wherein table size is not made larger because the number of table access times per code word is set to a maximum of 2, and plural code words are decoded by one table access operation to attain high-speed decoding.
