Abstract:
1. A video and audio processing device comprising: at least one specific-standard digital input terminal into which specific-standard digital data including video data and audio data is fed; at least one analog video input terminal into which an analog video signal is fed; at least one specific-standard digital output terminal from which the specific-standard digital data is output; at least one analog video output terminal from which the analog video signal is output; a receiving unit that receives the specific-standard digital data fed into the specific-standard digital input terminal and produces video data and/or audio data from the specific-standard digital data; 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”, wherein 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”.
