DXVA_COPPSetSignalingCmdData Structure
Contains information for the Set Signal command in Certified Output Protection Protocol (COPP).
Syntax
typedef struct _DXVA_COPPSetSignalingCmdData { ULONG ActiveTVProtectionStandard; ULONG AspectRatioChangeMask1; ULONG AspectRatioData1; ULONG AspectRatioChangeMask2; ULONG AspectRatioData2; ULONG AspectRatioChangeMask3; ULONG AspectRatioData3; ULONG ExtendedInfoChangeMask[4]; ULONG ExtendedInfoData[4]; ULONG Reserved; } DXVA_COPPSetSignalingCmdData;
Members
ActiveTVProtectionStandard
Specifies the protection standard and format that is current active. The value is a member of the COPP_TVProtectionStandard enumeration.
AspectRatioChangeMask1
Bit mask indicating which bits in AspectRatioData1 to change.
AspectRatioData1
Specifies the aspect ratio value to be set for the current protection standard. For EN 300 294, the value is a member of the COPP_ImageAspectRatio_EN300294 enumeration.
AspectRatioChangeMask2
Bit mask indicating which bits in AspectRatioData2 to change.
AspectRatioData2
Additional data element related to aspect ratio for the current protection standard. The presence and meaning of this data depends on the protection standard. This field may be used to convey End and Q0 bits for EIA-608-B, or the active format description for CEA-805-A.
AspectRatioChangeMask3
Bit mask indicating which bits in AspectRatioData3 to change.
AspectRatioData3
Additional data element related to aspect ratio for the current protection standard. The presence and meaning of this data depends on the protection standard.
ExtendedInfoChangeMask
Array of bit masks indicating which bits in ExtendedInfoData to change.
ExtendedInfoData
Additional signaling elements to be set. This array is currently not used.
