IBDA_DRM Interface

This topic applies to Windows Vista.

The IBDA_DRM interface is used to request a tuner to perform a DRM handshake with the user's computer. Some tuners require a DRM handshake to verify that the user can receive content from the tuner. The BDA tuner filter exposes this interface; it is implemented by the tuner mini-driver.

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

In addition to the methods inherited from IUnknown, the IBDA_DRM interface exposes the following methods.

Method Description
GetDRMPairingStatus Queries the status of the DRM handshake.
