COPP_HDCP_Protection_Level Enumeration

Specifies the HDCP protection level.

Syntax

  typedef enum _COPP_HDCP_Protection_Level {
  COPP_HDCP_Level0    = 0,
  COPP_HDCP_LevelMin  = COPP_HDCP_Level0,
  COPP_HDCP_Level1    = 1,
  COPP_HDCP_LevelMax  = COPP_HDCP_Level1,
  COPP_HDCP_ForceDWORD = 0x7fffffff
} COPP_HDCP_Protection_Level;

Members

COPP_HDCP_Level0

HDCP protection is not enabled. See Remarks.

COPP_HDCP_LevelMin

Minimum HDCP level. Equivalent to COPP_HDCP_Level0.

COPP_HDCP_Level1

HDCP is enabled.

COPP_HDCP_LevelMax

Maximum HDCP level. Equivalent to COPP_HDCP_Level1.

COPP_HDCP_ForceDWORD

Reserved.

Remarks

Some televisions do not have robust support for switching HDCP protection on and off. Because of this limitation, the graphics driver might leave HDCP enabled when the application sets the protection level to zero. If the application sets the HDCP level to zero, therefore, it might receive a COPP status message indicating that HDCP is still enabled. This is not an error.
