DXGKMDT_OPM_CONNECTED_HDCP_DEVICE_INFORMATION structure (d3dkmdt.h)
The DXGKMDT_OPM_CONNECTED_HDCP_DEVICE_INFORMATION structure contains High-bandwidth Digital Content Protection (HDCP) information that is retrieved in a call to the DxgkDdiOPMGetInformation function.
Syntax

ULONG ulHDCPFlags;
DXGKMDT_OPM_HDCP_KEY_SELECTION_VECTOR ksvB;

BYTE Reserved2[16];
BYTE Reserved3[16];
} DXGKMDT_OPM_CONNECTED_HDCP_DEVICE_INFORMATION;
Members
rnRandomNumber
A DXGKMDT_OPM_RANDOM_NUMBER structure that contains a protected output object's 128-bit cryptographically secure random number. This random number is generated by an application and supplied to the display miniport driver in the rnRandomNumber member of the DXGKMDT_OPM_COPP_COMPATIBLE_GET_INFO_PARAMETERS structure in a call to the driver's DxgkDdiOPMGetCOPPCompatibleInformation function.
ulStatusFlags
A bitwise OR combination of the values of the DXGKMDT_OPM_STATUS enumeration that indicates the status of a protected output.
ulHDCPFlags
A bitwise OR combination of the values of the DXGKMDT_OPM_HDCP_FLAG enumeration that identifies whether a protected output's physical connector is connected to a High-bandwidth Digital Content Protection (HDCP) repeater.
ksvB
A DXGKMDT_OPM_HDCP_KEY_SELECTION_VECTOR structure that contains a key-selection vector (KSV) for a monitor or an HDCP repeater. An HDCP receiver is typically a monitor. An HDCP repeater is a device that allows multiple monitors to display the video signal from a protected output's physical connector. For more information about HDCP receivers and repeaters, see the HDCP Specification Revision 1.1.
Reserved[11]
Reserved. Must be set to zero.
Reserved2[16]
Reserved. Must be set to zero.
Reserved3[16]
Reserved. Must be set to zero.
