Abstract
An apparatus for at least receiving digital information including digital video information bit-compressed by a first compression system plus digital audio information bit-compressed by a second compression system 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, 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.
