Abstract
A digital processing unit for converting a digital picture signal into data by blocks and for correction encoding a variable-length encoded signal. This digital processing unit includes a digital data compressing section for dividing a picture signal into a plurality of number of blocks, and compressingly outputting digital data of this picture signal based on a processing unit of one or a few blocks, a buffer section for sequentially storing the digital data, and an error correction encoding section for sequentially reading the digital data from this buffer section, and structuring an inner code for each inner block structured by this digital data and structuring an outer code for each predetermined unit of inner blocks, to thereby structure two-dimensional error correction code blocks, to output an error correction code signal. Further, the error correction encoding section has the length of the digital data of the picture signal included in the inner code set to be equal to or larger than a mean code length of predetermined compressed blocks.
