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. |
| PerformDRMPairing | Requests the tuner to perform a DRM handshake. |
