DXGKMDT_OPM_HDCP_PROTECTION_LEVEL enumeration (d3dkmdt.h)

  • Article

The DXGKMDT_OPM_HDCP_PROTECTION_LEVEL enumeration indicates the protection levels for a protected output that supports High-bandwidth Digital Content Protection (HDCP).

Syntax

typedef enum _DXGKMDT_OPM_HDCP_PROTECTION_LEVEL {
  DXGKMDT_OPM_HDCP_OFF,
  DXGKMDT_OPM_HDCP_ON,
  DXGKMDT_OPM_HDCP_FORCE_ULONG
} DXGKMDT_OPM_HDCP_PROTECTION_LEVEL;

Constants

 
DXGKMDT_OPM_HDCP_OFF
Indicates that HDCP does not protect the output's signal.
DXGKMDT_OPM_HDCP_ON
Indicates that HDCP protects the output's signal.
DXGKMDT_OPM_HDCP_FORCE_ULONG
Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. You should not use this value.

Remarks

HDCP protects digital video signals from digital video output connectors. Currently, OPM can use HDCP to protect data from Digital Video Interface (DVI) and High-Definition Multimedia Interface (HDMI) connector outputs. For more information about the HDCP system, see the HDCP Specification Revision 1.1.
