A digital signal recording and reproducing apparatus has the following components: a digital information decoding circuit for outputting (a) a received digital information signal by selecting a channel, and (b) a first analog signal by selecting and decoding either one of a selected digital information signal, and a reproduced digital information signal of a recording medium; a recording and reproducing unit for outputting a reproduced digital signal, comprising (a) a digital signal recording unit for inputting the digital information signal of the channel selected and output by the digital information decoding circuit, and for recording on the recording medium, (b) a digital signal reproduction unit for reproducing the digital signal recorded on the recording medium, and (c) a first recording and reproduction unit for recording and reproducing an externally input analog video/audio signal on the recording medium as a second analog signal; a bus line for transmitting (a) the digital information signal of the channel selected and output by the digital information decoding circuit to the recording and reproducing unit, and (b) a digital information signal output by the recording and reproducing unit to the digital information decoding circuit; and an analog information selecting circuit for selecting and outputting either one of (a) the first analog signal decoded by the digital information decoding circuit, and (b) the second analog signal reproduced by the recording and reproducing unit.
