KSPROPERTY_TUNER_IF_MEDIUM_S structure (ksmedia.h)
The KSPROPERTY_TUNER_IF_MEDIUM_S structure returns the Medium GUID for the pin that is capable of supporting tuning to an intermediate frequency.
Syntax
typedef struct {
KSPROPERTY Property;
KSPIN_MEDIUM IFMedium;
} KSPROPERTY_TUNER_IF_MEDIUM_S, *PKSPROPERTY_TUNER_IF_MEDIUM_S;
Members
Property
Specifies an initialized KSPROPERTY structure that describes the property set, property ID, and request type.
IFMedium
Specifies the GUID for the pin that is capable of supporting an intermediate frequency. If no pin supports an intermediate frequency, the minidriver should return GUID_NULL.
Remarks
Support for the KSPROPERTY_TUNER_IF_MEDIUM property causes Kstvtune.ax to create an additional pin representing an MPEG-2 transport stream. A data packet sent on this pin in user mode consists only of a KS_TVTUNER_CHANGE_INFO structure.
