Abstract:
1. A digital information receiving apparatus, comprising: a receiver configured to receive digital information from a transmission path, wherein the digital information includes video information bit-compressed by a first compression method, audio information bit-compressed by a second compression method which is different from the first compression method, and error detection information added to the video information and separately added to the audio information, respectively; a demodulator configured to demodulate the digital information received by the receiver; an error detector configured to detect an error which occurs in the transmission path of the digital information demodulated by the demodulator based on the error detection information, the error being the error which occurs in the transmission path having no recording process of the digital information therein; a first expander configured to bit-expand the video information of the digital information error detected by the error detector in accordance with a first expansion method corresponding to the first compression method; and a second expander configured to bit-expand the audio information of the digital information error detected by the error detector in accordance with a second expansion method corresponding to the second compression method.
