DXGKMDT_OPM_CONNECTED_HDCP_DEVICE_INFORMATION structure
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
typedef struct _DXGKMDT_OPM_CONNECTED_HDCP_DEVICE_INFORMATION { DXGKMDT_OPM_RANDOM_NUMBER rnRandomNumber; ULONG ulStatusFlags; ULONG ulHDCPFlags; DXGKMDT_OPM_HDCP_KEY_SELECTION_VECTOR ksvB; BYTE Reserved[11]; 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.
