IBDA_SignalStatistics interface (bdaiface.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The IBDA_SignalStatistics interface is implemented on a BDA device filter and provides methods by which the filter can describe the condition of a signal that is being received.
Inheritance
The IBDA_SignalStatistics interface inherits from the IUnknown interface. IBDA_SignalStatistics also has these types of members:
Methods
The IBDA_SignalStatistics interface has these methods.
| IBDA_SignalStatistics::get_SampleTime The get_SampleTime method retrieves the sample time used to measure the signal. |
| IBDA_SignalStatistics::get_SignalLocked The get_SignalLocked method retrieves a Boolean value indicating whether the signal is locked. |
| IBDA_SignalStatistics::get_SignalPresent The get_SignalPresent method retrieves a Boolean value indicating whether a signal is present. |
| IBDA_SignalStatistics::get_SignalQuality The get_SignalQuality method retrieves a value from 1 to 100 indicating the quality of the signal. |
| IBDA_SignalStatistics::get_SignalStrength The get_SignalStrength method retrieves a value that indicates the strength of the signal in decibels. |
| IBDA_SignalStatistics::put_SampleTime The put_SampleTime method specifies the sample time of the signal. |
| IBDA_SignalStatistics::put_SignalLocked The put_SignalLocked method specifies whether the signal is locked. |
| IBDA_SignalStatistics::put_SignalPresent The put_SignalPresent method specifies whether a signal is present. |
| IBDA_SignalStatistics::put_SignalQuality The put_SignalQuality method specifies the quality of the signal. |
| IBDA_SignalStatistics::put_SignalStrength The put_SignalStrength method specifies the strength of the signal in decibels. |
Remarks
To declare the interface identifier (IID) for this interface, use the __uuidof operator: __uuidof(IBDA_SignalStatistics).
