METHOD OF AND APPARATUS FOR ENCODING DIGITAL SIGNALS, RECORD MEDIUM THEREFOR AND METHOD OF AND APPARATUS FOR DECODING SUCH RECORDED SIGNALS

摘要

In a digital signal encoding method and apparatus, a digital signal recording medium and a digital signal decoding method and apparatus, the present invention improves an error correction capacity by a simple construction and reduces redundancy in encoding and decoding with digital signals error-correcting codes. When a digital signal is encoded with an error-correcting code, it is provided with a longer code length, more parity bits, and a longer interleave restriction length than specified by a compact disk standard so that redundancy can be reduced in comparison with the compact disk standard and a recordable data quantity can be increased. $$
