IBDA_SignalProperties Interface

This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005 and later.

The IBDA_SignalProperties interface is implemented by a BDA device filter. Through this interface, the network provider informs a BDA device filter about the current tuning request. The network provider calls the PutXxx methods in the interface at the time that the BDA device is registered with the network provider. Thereafter, the network provider calls these methods whenever the current tuning request is modified.

In addition to the methods inherited from IUnknown, the IBDA_SignalProperties interface exposes the following methods.

Method Description
GetNetworkType Retrieves the network type for the current tuning request.
GetSignalSource Retrieves the signal source for the current tuning request.
GetTuningSpace Retrieves the tuning space for the current tuning request.
PutNetworkType Specifies the network type for the current tuning request.
PutSignalSource Specifies the signal source for the current tuning request.
PutTuningSpace Specifies the tuning space for the current tuning request.
