摘要： A record unit of coded video data is concealed. The record unit is reproduced from a recording medium and has a first recording block containing a part of a coded video data A which has been obtained by coding m blocks of video data among a plurality of blocks of video data divided from video data of one page, a second recording block containing a part of a coded video data B which has been obtained by coding other m blocks of video data among the plurality of blocks of video data and a third recording block containing in a first part thereof the remaining part of the coded video data A and in a second part thereof the remaining part of the coded video data B. The record unit also contains an address data indicating an address of a border of the first and second parts of the third recording block. The record unit of the coded video data is concealed by detecting an error position where an error of coded video data exists in the record unit, detecting the address data contained in the record unit, comparing the detected address data with an address data contained in a corresponding record unit of a previous page, and determining which part of the record unit should be replaced by a corresponding part of the corresponding record unit of the previous page according to the error position and a comparison result. The part of the record unit thus determined is replaced by a corresponding part of the corresponding record unit of the previous page to thereby conceal the record unit.

摘要： A digital video signal is shuffled such that blocks of a luminance signal and a chrominance signal existing at a same position on an image plane are contained in a same segment recorded on a recording medium or in a plurality of segments recorded simultaneously in parallel using a plurality of channels. Thus, the luminance signal and chrominance signal being at the same position on the image plane are always obtainable simultaneously even during high-speed reproducing in a digital VTR.

摘要： In an encoder for selectively receiving, blocking and coding by orthogonal transformation an image A with a screen aspect ratio which is greater than 4:3 or an image B with a screen aspect ratio of 4:3, when the image A is entered, it is divided into a basic screen with an aspect ratio of 4:3 corresponding to a central portion of a screen and an additional screen other than the basic screen. Coding is controlled so that a sum of coded data quantity of a specified number of blocks m of orthogonal transformation of the basic screen and a specified number of blocks n of orthogonal transformation of the additional screen is within a specified data quantity x. When the image B is entered, the coding is controlled so that a coded data quantity of the same number of blocks of orthogonal transformation as the specified number of blocks of orthogonal transformation m of the basic screen of the image A is within the same data quantity as the specified data quantity x.

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.
