The KSPROPERTY_TUNER_CAPS_S structure describes the hardware capabilities of TV and radio tuning devices.
PropertySpecifies an initialized KSPROPERTY structure that describes the property set, property ID, and request type.
ModesSupportedSpecifies a bitwise OR of the supported tuner modes. This member may be set to one or more of the following values from the KSPROPERTY_TUNER_MODES enumeration that is defined in ksmedia.h:
| Flag | Meaning |
|---|---|
| KSPROPERTY_TUNER_MODE_TV | Indicates that the tuner is capable of tuning analog broadcast or cable television channels. |
| KSPROPERTY_TUNER_MODE_FM_RADIO | Indicates that the tuner is capable of tuning FM radio channels. |
| KSPROPERTY_TUNER_MODE_AM_RADIO | Indicates that the tuner is capable of tuning AM radio channels. |
| KSPROPERTY_TUNER_MODE_DSS | Indicates that the tuner is capable of tuning DSS channels. |
| KSPROPERTY_TUNER_MODE_ATSC | Indicates that the tuner is capable of tuning digital television channels. This setting can be used for ATSC, DVB-C, or DVB-T television reception. |
VideoMediumSpecifies a unique GUID representing the hardware connection of the analog video signal. This value enforces connections between filters. Possible values are NULL, indicating that no pin is created; GUID_NULL, indicating that Medium is not used to enforce connections; or a GUID. If a GUID value is used, only crossbar pins with a matching Medium GUID are allowed to connect.
TVAudioMediumSpecifies a unique GUID representing the hardware connection of the TV audio signal. This value enforces connections between filters. Possible values are NULL, indicating that no pin is created; GUID_NULL, indicating that Medium is not used to enforce connections; or a GUID. If a GUID value is used, only crossbar pins with a matching Medium GUID are allowed to connect.
RadioAudioMediumSpecifies a unique GUID representing the hardware connection of the analog radio audio signal. This value enforces connections between filters. Possible values are NULL, indicating that no pin is created; GUID_NULL, indicating that Medium is not used to enforce connections; or a GUID. If a GUID value is used, only crossbar pins with a matching Medium GUID are allowed to connect.
