<p>In a digital VTR that carries out magnetic recording and reproduction by bit rate reduction coding a digital video signal, a fixed length block is formed by controlling the code amount of a large block including a plurality of small blocks located distant from each other on a screen at the time of recording. The fixed length block is divided into a plurality of recording blocks so that the main components of respective small blocks are included separately on the recording blocks, whereby error correction is applied to form a plurality of error correction blocks. The error correction blocks are rearranged so that recording blocks including the main components of small blocks adjacent on a screen are also adjacent on a recording medium. Thus, the possibility of deviation in the information amount of each large block is suppressed to improve efficiency of bit rate reduction coding, and to obtain a high speed reproduced picture of high quality. <IMAGE></p> |
