IBDA_DRM 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_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.
