Estimating the term…
An apparatus for receiving digital information including at least one of digital video information and digital audio information. The apparatus includes 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 received digital information, and an error detector which detects an error of digital information demodulated by the demodulator. A first expander bit-expands video information among the digital information which is error detected corresponding to the first compression system, and a second expander bit-expands audio information among the digital information which is error detected corresponding to the second compression system.
(canceled)
A digital information receiving method used in a digital information transmitting and receiving system, wherein the digital information includes video information and audio information, and the video information is compressed by a first compression system using a discrete cosine transform and the audio information is compressed by a second compression system, comprising the steps of:
