    • An error correcting decoder includes a flag memory (20) which stores a flag indicative of a success of an error correction for a bit. When a column direction error correction is to be performed, if a flag for a bit indicates a success, no error correction is performed for the bit. That is, an output of a majority logic circuit (78) is forcedly made invalid. In performing the column direction error correction, if the number of success packets in a first-time row direction error correction is smaller than a predetermined value and if the number of bits corrected by the column direction error correction becomes equal to or larger than a predetermined number, it is deemed as that the column direction error correction is unsuccessful. In performing a second-time row direction error correction, when a threshold value is equal to or larger than a predetermined value, the majority logic circuit determines with referring to a result of the column direction error correction, but without referring to the result when the threshold value is smaller than the predetermined value.
    • 纠错解码器包括标志存储器(20),其存储指示针对位的纠错成功的标志。 当要执行列方向错误校正时,如果位的标志指示成功,则不对该位执行纠错。 也就是说,多数逻辑电路(78)的输出被强制地变为无效。 在执行列方向误差校正时,如果第一行方向误差校正中的成功分组数小于预定值,并且如果通过列方向误差校正校正的比特数等于或大于预定值 号码,则视为列方向错误校正不成功。 在执行第二次行方向误差校正时,当阈值等于或大于预定值时,多数逻辑电路参考列方向误差校正的结果确定,但是不参考结果时 阈值小于预定值。

    • Method and apparatus for transmitting an information signal generate a plurality of block signals on the basis of the information signal, generate a plurality of parity block signals on the basis of the plural data block signals, generate a frame signal containing the plural data block signals and the parity block signals, and send out the frame signal. Each of the data block signals includes a first block synchronizing signal indicating the start of the data block signal, a data signal containing the information signal and a first parity signal derived by encoding the data signal. Each of the parity block signals incudes a second block synchronizing signal indicating the start of the parity block signal, a second parity signal and a third parity signal. Bit signals located at same bit positions in the respective second parity signals are derived by encoding bit signals located at the same positions in the respective data signals. Bit signals located at same bit positions in the respective third parity signals are derived by encoding the bit signals located at the same bit positions in the respective first parity signals or alternatively the third parity signal in each parity block signal is derived by encoding the second parity signal in each parity block signal.
