Abstract
A digital video signal recording apparatus records 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. For the 525/60 NTSC system with 3-segment and 4-channel arrangement, one field video signal is stored in three segments. The recording apparatus has a standard channel order generator for generating a standard channel order of a recurring channel pattern. The four digital components are aligned based on the recurring channel pattern so that the 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. As a result, the samples for the same-position pixels are recorded by the same recording head, adjacent samples are recorded by different heads, and error concealment functions effectively.
