Digital information recording/reproducing apparatus
First Claim
1. An apparatus for receiving digital information, comprising:
- 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;
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.

Abstract
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.

6. An apparatus for processing a transmitted digital signal, comprising:
-
a receiver which receives the transmitted digital signal, wherein the transmitted digital signal includes a video signal bit-compressed by a first compression method, an audio signal bit-compressed by a second compression method, and an error correction signal added commonly to both the video signal and the audio signal;
a demodulator which demodulates the digital signal received by the receiver;
an error corrector which corrects an error of the digital signal demodulated by the demodulator based on the error correction signal;
a first expander which bit-expands the video signal of the digital signal corrected by the error corrector in accordance with the first compression method; and
a second expander which bit-expands the audio signal of the digital signal corrected by the error corrector in accordance with the second compression method. - View Dependent Claims (7)
