The IBDA_DigitalDemodulator interface is exposed on BDA device filters, specifically demodulators, that are not capable of automatically detecting the characteristics of a signal. A Network Provider calls these methods on the filter to provide the demodulator with the information it needs to acquire a particular signal. The Network Provider obtains these values from the Locator object associated with the tune request or tuning space.
OCUR Devices: This interface supports OpenCable Unidirectional Cable Receiver (OCUR) devices. See OCUR Devices.
Methods
The IBDA_DigitalDemodulator interface inherits the methods of the IUnknown interface.
In addition, IBDA_DigitalDemodulator defines the following methods.
| Method | Description |
|---|---|
Retrieves the inner forward error correction method. |
|
Retrieves the inner forward error correction rate being used on the signal. |
|
Retrieves the modulation type for the signal. |
|
Retrieves the outer forward error correction method for the signal. |
|
Retrieves the outer forward error correction rate for the signal. |
|
Retrieves the spectral inversion value for the signal. |
|
Retrieves the symbol rate for the signal. |
|
Specifies the inner forward error correction method for the signal. |
|
