摘要

In a digital VCR, which carries out bit rate reduction coding of digital video signals for magnetically recording and reproducing the same, a plurality of blocks each including the digital video signal of a plurality of pixels are formed, and the digital video signals are encoded for each block. A code amount is controlled so that the code amount may be constant on the basis of one or more of the plurality of blocks, and encoding is carried out for correcting a possible error, whereby error correction blocks are formed. The error correction blocks are rearranged so that the error correction blocks included in the blocks, which are adjacent to each other in a screen, may be adjacent to each other on a recording medium, and the data for three rectangular regions, which are obtained by trisecting the screen with respect to the horizontal direction, may be recorded in corresponding three tracks. Thereby, mosaic deformation in a reproduced picture can be prevented.
