Abstract: An apparatus for receiving/recording digital information. The receiving apparatus receives digital information which is a digital video information bit-compressed by a first compression system using discrete cosine transform plus digital audio information bit-compressed for error detecting, phase-modulated and transmitted to a transmission path. The receiver apparatus includes a receiver which receives the transmitted digital information, a demodulator which demodulates the digital information received by the receiver corresponding to the phase-modulation, an error detector which detects an error of a digital information demodulated by the demodulator by use of a parity signal, a first expander which bit-expands video information among digital information error detected by the error detector corresponding to the first compression system and a second expander which bit-expands audio information among digital information error detected by the error detector corresponding to the second compression system.
