The property value (operation data) is a KSPIN_MEDIUM structure that specifies the Medium GUID for the pin that is capable of supporting tuning to an intermediate frequency.
Remarks
The IFMedium member of the KSPROPERTY_TUNER_IF_MEDIUM_S structure specifies the Medium GUID of the intermediate frequency pin.
If the video capture minidriver supports KSPROPERTY_TUNER_IF_MEDIUM, then kstvtune.ax creates an additional pin that represents the hardware-based MPEG-2 transport stream originating at the tuner. This pin is used solely to define graph topology. Data samples flowing through the user-mode stream from this pin on kstvtune.ax consist of KS_TVTUNER_CHANGE_INFO structures.
