  • Patent number: 4829525
    Abstract: A digital signal reproducing apparatus reproduces coded digital signal data which have been recorded on a magnetic tape. The digital signal reproducing apparatus includes first and second decoders. These decoders perform the error correction and erasure correction. The second decoder has a higher error detection capability than that of the first decoder. The reproducing apparatus further includes a checking circuit for checking code errors contained in the coded digital signal data. When the code errors detected by the checking circuit may occur simultaneously, a first editing-point detection signal is produced. When the first editing-point detection signal is output, a judgement is done that the editing-point may exist in the digital signal data, and the first decoder is changed to the second decoder for a predetermined time period. When the second decoder detects correction-prohibited data portion, a second editing-point detection signal.
