Patent attributes
An apparatus for receiving digital information including a receiver which receives the digital information that has digital video information bit-compressed by a first compression system, digital audio information bit-compressed by a second compression system, and error-detection information added to both the digital video information and the digital audio information. There is also provided a demodulator which demodulates the digital information received by the receiver, an error detector which detects an error of digital information demodulated by the demodulator by use of the error-detection information, a first expander which bit-expands video information among the digital information error detected by the error detector corresponding system, and a second expander which bit-expands audio information among the digital information error detected by the error detector corresponding to the second compression system.
