IBDA_FrequencyFilter 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_FrequencyFilter interface is implemented on a BDA tuner device, and is used by the Network Provider to tell the tuner how to set its frequencies.
Inheritance
The IBDA_FrequencyFilter interface inherits from the IUnknown interface. IBDA_FrequencyFilter also has these types of members:
Methods
The IBDA_FrequencyFilter interface has these methods.
| IBDA_FrequencyFilter::get_Autotune The get_Autotune method retrieves the autotune frequency. |
| IBDA_FrequencyFilter::get_Bandwidth The get_Bandwidth method retrieves the bandwidth. |
| IBDA_FrequencyFilter::get_Frequency The get_Frequency method retrieves the frequency. |
| IBDA_FrequencyFilter::get_FrequencyMultiplier The get_FrequencyMultiplier method retrieves the frequency multiplier. The frequency multiplier determines the frequency units for the methods on this interface. The default value is 1000, meaning that frequencies are expressed in kilohertz (kHz). |
| IBDA_FrequencyFilter::get_Polarity The get_Polarity method retrieves the polarity. |
| IBDA_FrequencyFilter::get_Range The get_Range method retrieves the tuner range. The tuner range is the frequency domain on which to find a particular carrier frequency. |
| IBDA_FrequencyFilter::put_Autotune The put_Autotune method specifies whether to activate the device's autotune capabilities. |
| IBDA_FrequencyFilter::put_Bandwidth The put_Bandwidth method specifies the bandwidth. |
| IBDA_FrequencyFilter::put_Frequency The put_Frequency method specifies the frequency. |
| IBDA_FrequencyFilter::put_FrequencyMultiplier The put_FrequencyMultiplier method specifies the frequency multiplier. The frequency multiplier determines the frequency units for the methods on this interface. The default value is 1000, meaning that frequencies are expressed in kilohertz (kHz). |
| IBDA_FrequencyFilter::put_Polarity The put_Polarity method specifies the polarity of the signal. |
| IBDA_FrequencyFilter::put_Range The put_Range method specifies the tuner range. The tuner range is the frequency domain on which to find a particular carrier frequency. |
Remarks
To declare the interface identifier (IID) for this interface, use the __uuidof operator: __uuidof(IBDA_FrequencyFilter).
