The AuxInTuningSpace object represents an auxiliary video input such as composite video or S-video.

Applications should get this object from the SystemTuningSpaces collection. See Default Tuning Spaces.

Tune request objects created by this tuning space support the ITuneRequest and IChannelTuneRequest interfaces. The channel number indicates the input source:

When the Video Control receives an AuxIn tune request, it creates a WDM analog TV filter graph and uses the crossbar filter to select the input.
