  • Compact disc subcode packing and error correction detection
    Patent number: 6591392
    Abstract: A subcode processing circuit of an optical disc drive, and a method for processing subcode data are disclosed. The subcode processing circuit includes a shift register circuit for processing a plurality of standard subcode data bytes that are obtained from an optical disc media of the optical disc drive. The processing is configured to pack the plurality of standard subcode data bytes into a plurality of packed subcode data bytes. The plurality of packed subcode data bytes is configured to be less than the plurality of standard subcode data bytes. In one example, the shift register circuit is configured to include a plurality of shift registers and a multiplexer to assist in the processing. The subcode processing circuit is further configured to perform error correction for each byte of the plurality of packed subcode data bytes.
