PURPOSE:To secure the resolution degree concerning the static part in a picture plane by recording and reproducing simultaneously the information to show that in which field the correspondence between N kinds of picture element arrangements and channels occurs to respective fields. CONSTITUTION:An input picture signal 3 is converted to digital picture data 5 by an A/D converter 4, and enters a channel distributing device 6. At the distributing device 6, the position is alternately replaced for each frame and the arrangement information showing which arrangement is obtained is inserted into the data 7 of respective channels, for example, after the synchronizing data. The data 7, next, forms an error correcting code by channels A and B recording devices 8 and respectively recorded to a tape 10 by a recording head 9. At reproducing, the recorded data are reproduced by a reproducing head 11, error-corrected by channels A and B reproducing devices 12 and outputted as data 13, and simultaneously, arrangement information 14 is also outputted, and the correspondence between a picture element arrangement and a channel is known by an arrangement information detecting device 15.
