Abstract:
A digital information receiving and recording/reproducing apparatus for receiving and recording/reproducing a transmitted, bit-compressed digital information, comprising:reception means for receiving the bit-compressed digital information;first demodulation means for demodulating an output signal from said reception means;first error correction means for correcting errors in an output signal from said first demodulation means;parity signal adding means for adding a parity signal to the compressed information from said first error correction means;modulation means for modulating the parity signal added compressed information added by said parity signal adding means;recording/reproducing means for recording/reproducing the compressed information modulated by said modulation means;second demodulation means for demodulating the compressed information reproduced by said recording/reproducing means so as to correspond to the modulation effected by said modulation means;second error correction means for error correcting the compressed information demodulated by said second demodulation means based upon said parity signal;bit-expansion means for bit-expanding the compressed information from said second error correction means; and output means for outputting the bit-expanded information expanded by said bit-expansion means.
