IBDA_AutoDemodulateEx 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_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.
