KSPROPERTY_TUNER_IF_MEDIUM_S structure

Description

The KSPROPERTY_TUNER_IF_MEDIUM_S structure returns the Medium GUID for the pin that is capable of supporting tuning to an intermediate frequency.

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.
