IBDA_DigitalDemodulator Interface

  • Article

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

get_InnerFECMethod

get_OuterFECMethod

Retrieves the outer forward error correction method for the signal.

get_OuterFECRate

Retrieves the outer forward error correction rate for the signal.

get_SpectralInversion

Retrieves the spectral inversion value for the signal.

get_SymbolRate

Retrieves the symbol rate for the signal.
