Note: The Automated Test System now has to put the source device into the proper video and audio mode (i.e.
resolution, colorimetry, audio format etc.). If you are certain that the source is in the proper mode executing the
following command (vinfo) is optional. Otherwise the Automated Test System would have to parse out the
command response and issue a notification to the operator.
