Abstract

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.
