    摘要： A video signal digital recording and reproducing apparatus includes: a rearranging section for rearranging a sequence of signals on a rectangular unit by rectangular unit basis formed by sectioning a group of pixel data on a screen of a digital video signal; an encoding section for subjecting the signals in the rectangular units to bit rate reduction; a block forming section for gathering plural number of the coded rectangular units to constitute a block of signals, and a recording the block of signals section for recording on a recording medium. The rearranging section divides the screen into plural regions, takes out the rectangular units by a certain number in order from each region, and carries out rearrangement so that mutually corresponding rectangular units which are contained respectively in adjacent blocks on the recording medium are mutually adjacent on the screen. The recording section is constituted so that the blocks signals are recorded simultaneously in parallel on the recording medium by using plural channels. The rearranging section may have such a constitution that the screen is divided into plural regions and the rectangular units are taken out by a certain number in order from each region, and rearrangement is carried out to that mutually corresponding rectangular units which are contained respectively in adjacent or neighboring blocks to be simultaneously recorded in parallel by the plural channels on the recording section are mutually adjacent on the screen.

    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： The video signal input is converted to high-speed reproduction data by a high-speed reproduction data encoder 1. The video signal input is converted to high-speed reproduction data by a formatter 2, which formats the high-speed reproduction data so that the same data is recorded to n tracks. After the recorded data is input to an error correction encoder 3, it is decoded by a decoder 4 and recorded by a recording head 5 to the magnetic tape 6. During reproduction, the recorded data is reproduced by reproduction head 7 from the magnetic tape 6, and decoded by decoder 8. The decoded data is then error corrected by an error correction decoder 9, and then input to a deformatter 10. The deformatter 10 separates the normal reproduction data from the high-speed reproduction data, and separately outputs both data types. During normal reproduction, the normal reproduction data is output by a switch 13; the high-speed reproduction data is decoded to video data by a high-speed reproduction data decoder during high speed reproduction, and output.
