A video signal receiving device comprises signal processing units (20b, 20c) which separate video components and audio components from received signals conforming to HDM= standard, and carry out a decoding process on the components, respectively, to thereby restore analog video signals and audio signals, a detecting unit (20a) which detects a change in received signals to generate a first detection signal, and a detecting unit (20e) which detects a change in a received connection recognition signal to generate a second detection signal, and a mute control unit (20d) which carries out a mute process for the signal processing units (20b, 20c) not to output audio signals. |
