Abstract:
Digital signal recording/reproducing apparatus for recording a digital sigal and reproducing a digital signal from a record medium, comprising:a recording path including: a compression code encoder for compressing an input digital signal, and an error correction code (ECC) encoder for ECC encoding the signal compressed by said compression code encoder; a recording unit for recording on said record medium the ECC encoded compressed signal received via said recording signal path; and a reproducing unit for reproducing a signal from said record medium; a reproducing path including: an error corrector for receiving a reproduced ECC encoded compressed signal from said reproducing unit and ECC decoding the reproduced signal, and a compression code decoder signal for receiving and decompressing the ECC decoded signal from said error corrector; a bypass signal path connected from an output of said ECC encoder in said recording path to an input of said error corrector; and a selector for selecting a decompressed ECC decoded signal derived from said reproducing path or from said bypass signal path.
