Abstract

PURPOSE:To dub data at a compressed low data rate by correcting only error which can be corrected by a dubbing output side and digital-outputting it as a form which an error correction code is added. CONSTITUTION:An A/D converter 10, a compressive encoder 11, an error corrective encoder 12, a recording encoder 13, a recording decoder 15, an error corrective decoder 16, a compressive decoder 17, a corrector 18 and a D/A converter 19 are provided. Then the digital output for dubbing is fetched after the error corrective decoder 16 and in this dubbing output, the error which can be corrected is corrected, the error which cannot be corrected is not corrected and the error is digital-outputted as the form added the error correction code. Thus, the corrected data is not recorded as the correct data and can be dubbed at the compressed low data rate when compression (high efficient encoding) is applied.
