Document Type and Number:
Japanese Patent JP2695195
Kind Code:
B2
Abstract:
Reed-Solomon outer code for error correction concatenated with a CRC inner code for detection of miscorrections. The error correction circuit has a parallel circuit of an RS coding sequence circuit 23 and a CRC coding sequence circuit 22 to form a sequence circuit and a control circuit 24 for selecting either one of them depending on the desired operation mode. High speed decoding is obtained since the CRC computation is carried out in parallel with the Reed-Solomon decoding operation.
