An error correction apparatus comprises a buffer memory for successively storing ECC error correction blocks included in the reproducing signal read from the optical disk in units of a row including a corresponding inner code parity, and an error correction means for successively performing an error correction on the read row by reading the column of information data stored in a buffer memory and said inner code parity corresponding to the column from among the ECC error correction block and using the read inner code parity in parallel with processing for storing the remaining data forming the ECC error correction block at a timing before all of data constituting the ECC error correction block is stored in the buffer memory.

A data decoding apparatus and the method and a data reproduction apparatus which reduces capacity of a memory used for decoding and speedily accesses to data to be read. In a data decoding apparatus ( ) and the method which decodes coded data (S ) which is recorded in a recording medium ( ), the coded data (S ) read from the recording medium ( ) is stored in a memory used for decoding ( ), data information of data to be read is detected from decoded data which is generated in the middle of decoding the coded data (S ), the data information is stored in a data information storage means and the output of decoded data (S ) is controlled on the based on the data information, thereby the output of the decoded data (S ) is controlled based on the data information independent of decoding of the coded data (S ).

Data decoding apparatus and method and data reproduction apparatus

A data decoding apparatus and the method and a data reproduction apparatus which reduces capacity of a memory used for decoding and speedily accesses to data to be read. In a data decoding apparatus (50) and the method which decodes coded data (S2) which is recorded in a recording medium (2), the coded data (S2) read from the recording medium (2) is stored in a memory used for decoding (51), data information of data to be read is detected from decoded data which is generated in the middle of decoding the coded data (S2), the data information is stored in a data information storage means and the output of decoded data (S10) is controlled on the based on the data information, thereby the output of the decoded data (S10) is controlled based on the data information independent of decoding of the coded data (S2).
