Abstract
Abstract 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 in high-speed reproducing in a digital VTR. <IMAGE>

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
94 words
A digital video signal recording apparatus comprising: shuffling means for rearranging the order of blocks of pixels of digital luminance and chrominance signals; encoding means for encoding each of the blocks to obtain coded blocks; segmenting means for forming segments each composed of a plurality of coded blocks; and recording means for recording said segments on a recording medium; wherein said shuffling means rearranges such that a block of a luminance signal and a block of a chrominance signal existing at a same position on an image plane are contained in a same segment.
Claim 2
Dependent Claim
104 words
A digital video signal reproducing apparatus comprising: detection means for detecting segments recorded on a recording medium by a digital video signal recording apparatus as claimed in claim 1; inverse-segmenting means for fetching coded blocks from said segments detected; decoding means for decoding said coded blocks to obtain blocks; and inverse-shuffling means for inversely rearranging the order of said blocks to obtain a luminance signal and a chrominance signal; wherein said inverse-shuffling means rearranges such that a block of a luminance signal and a block of a chrominance signal existing at a same position on an image plane are obtained from a same segment.
Claim 3
Dependent Claim
107 words
A digital video signal recording apparatus comprising: shuffling means for rearranging the order of blocks of pixels of digital luminance and chrominance signals; encoding means for encoding said blocks to obtain coded blocks; segmenting means for forming segments each composed of a plurality of coded blocks; recording means for recording said segments simultaneously in parallel on a recording medium using a plurality of channels; wherein said shuffling means rearranges such that blocks of luminance and chrominance signals existing at a same position on an image plane are contained in said plurality of segments to be recorded simultaneously in parallel on said medium using said plurality of channels.
Claim 4
Dependent Claim
114 words
A digital video signal reproducing apparatus comprising: detection means for detecting a segments recorded simultaneously in parallel on a recording medium using a digital video signal recording apparatus as claimed in claim 3; inverse-segmenting circuit for fetching coded blocks from said segments detected; decoding means for decoding said coded blocks to obtain blocks; and inverse-shuffling means for rearranging the order of said blocks to obtain a reproduced digital luminance and chrominance signals; wherein said inverse-shuffling means rearranges such that blocks of luminance and chrominance signals existing at a same position on an image plane are obtained from said plurality of segments formed simultaneously in parallel using said plurality of channels on said recording medium.
