Abstract

PURPOSE:To improve the error correcting ability concerning the data with a high importance and a restoring picture quality by executing the exclusive-use encoding to correct a random error for the data with the high importance at the time of a high efficient encoding. CONSTITUTION:A parity generating circuit 7 generates a parity PT1 to fixed length data with a high importance. The parity PT1 is an error correcting code for correcting a random error. A parity generating circuit 8 generates a parity PT2 of an external code. A parity generating circuit 9 generates a parity PT0 of an internal code. The output data of a reproducing memory 26 are supplied to an error correcting circuit 27 and the error correction of the internal code is executed. The error correction of the external code is executed by an error correcting circuit 29. By an error correcting circuit 31, the error correction for the fixed length data with the high importance is executed. Further, by the repeated correction, in order to raise the correction ability, the output data of the error correcting circuit 31 are supplied through a formatter 32 in a segment to an error correcting circuit 33 of the external code.
