Abstract

PURPOSE:To enable sure signal processing for the front and rear end of block data, by adding redundant data at both ends or one end of a plurality of data in block. CONSTITUTION:When the data for one horizontal line's share is subblocked every 1/6 line's share, m-sample is added at both ends of the data for original 1/6 line's share in case of the digital filter of the 2m order. As the additional signal, to the front end of data of the first subblock of the channel A and to the rear end of the data of subblock after the channel C, the value sampling the pedestal level is used as the digital signal in 8-bit, and to other front part of subblock data, the m units of data after the data of the subblock prior to it are used, and to other rear end of data of the subblock, the m units of data for the head of the next subblock are used.
