Digital video signal recording apparatus and method

A digital video signal recording apparatus for recording a video signal expressed by four digital components such that even numbered pixel is expressed by a first type luminance signal component and two color difference signal components, and odd numbered pixel is expressed by a second type luminance signal component, and that one field of said video signal is stored in a predetermined number of segments, said apparatus comprising:

• four different channels through which said four digital components are stored;
• standard channel order setting means for setting a standard channel order of a recurring channel pattern;
• aligning means for aligning channels based on said standard channel such that a first group is the standard channel order, and following groups take such an order that the standard channel order is shifted, after each group, by a first predetermined increment amount, and also that the channel order in one line is shifted, after each line, by a second predetermined increment amount;
• first allocating means for allocating said first and second type luminance signal components with said aligned channels;
• first assigning means for assigning sequentially said predetermined number of segments to said first and second type luminance signal components;
• second allocating means for allocating said two color difference signal components with channels based on said aligned channels such that every other channel data from said aligned channels are taken and each channel data is repeated twice;
• and
• second assigning means for assigning sequentially said predetermined number of segments to said two color difference signal components, whereby said first type luminance signal component and two color difference signal components for the even numbered pixel are stored in a same segment by the same channel.
