A video and audio processing device comprises: a switching unit that switches a video input and output pathway at least between "analog video input terminal-analog video output terminal" and "specific-standard digital input terminal-specific-standard digital output terminal"; an input determining unit that determines whether the specific-standard digital data is fed into the specific-standard digital input terminal; and a pathway determining unit that determines whether the video input and output pathway is "analog video input terminal-analog video output terminal". The receiving unit produces only the audio data from the specific-standard digital data, when the specific-standard digital data is fed into the specific-standard digital input terminal while the video input and output pathway is "analog video input terminal-analog video output terminal". |
