IBDA_AutoDemodulateEx Interface

This topic applies to Windows Vista.

The IBDA_AutoDemodulateEx interface extends IBDA_AutoDemodulate. If a BDA device filter, specifically a demodulator, exposes this interface, it indicates that the filter can automatically detect signal characteristics. With this information, the Network Provider can be more efficient in managing the tuning process. For more information, see KSPROPSETID_BdaAutodemodulate in the Windows DDK.

OCUR Devices: This interface supports OpenCable Unidirectional Cable Receiver (OCUR) devices. See OCUR Devices.

In addition to the methods inherited from IBDA_AutoDemodulate, the IBDA_AutoDemodulateEx interface exposes the following methods.

Method Description
get_AuxInputCount Retrieves a count of the number of auxiliary inputs on the demodulator.
get_SupportedDeviceNodeTypes Retrieves a list of the device node types that the demodulator supports.
get_SupportedVideoFormats Retrieves the video formats that are supported by the demodulator.
