Members
rApp
Specifies a 128-bit random number, used once. This random number is generated by the requesting application and supplied to the display driver in the rApp member of the DXVA_COPPStatusInput structure.
dwFlags
Specifies additional status information that might be relevant to the calling application. The display driver should set dwFlags to the COPP_StatusNormal (0x00) value from the COPP_StatusFlags enumeration type or to a valid ORed combination of the following COPP_StatusFlags:
- COPP_LinkLost (0x01)
- COPP_RenegotiationRequired (0x02)
AvailableTVProtectionStandards
Specifies a valid ORed combination of values from the COPP_TVProtectionStandard enumeration type that indicates the types of television signals that the physical connector associated with the DirectX VA COPP device can carry. For the list of signal types, see the ActiveTVProtectionStandard member of the DXVA_COPPSetSignalingCmdData structure.
ActiveTVProtectionStandard
Specifies a valid ORed combination of values from the COPP_TVProtectionStandard enumeration type that indicates the types of television signals that the physical connector associated with the DirectX VA COPP device currently carries. For the list of signal types, see the ActiveTVProtectionStandard member of the DXVA_COPPSetSignalingCmdData structure.
TVType
Specifies a value that indicates attributes of the connected display monitor that the driver is aware of. Not currently used.
AspectRatioValidMask1
Specifies the COPP_ImageAspectRatio_EN300294_Mask (0x00000007) constant that indicates that only the first three bits in the following AspectRatioData1 member are valid.
AspectRatioData1
Specifies one of the values from the COPP_ImageAspectRatio_EN300294 enumeration type to indicate an ETSI EN 300 294 value. For the list of values, see the AspectRatioData1 member of the DXVA_COPPSetSignalingCmdData structure.
AspectRatioValidMask2
Specifies a value that indicates the valid bitfields in the following AspectRatioData2 member.
AspectRatioData2
Specifies 32-bit data for additional aspect ratio-related data for specific protection standards. This data can be used to read End and Q0 values for EIA-608-B, or active format description for CEA-805-A Type B packets.
AspectRatioValidMask3
Specifies a value that indicates the valid bitfields in the following AspectRatioData3 member.
AspectRatioData3
Specifies 32-bit data for additional aspect ratio-related data for specific protection standards. This data can be used to read End and Q0 values for EIA-608-B, or active format description for CEA-805-A Type B packets.
ExtendedInfoValidMask[4]
Specifies an array of values that indicate the valid bitfields in the respective elements of the following ExtendedInfoData array member.
ExtendedInfoData[4]
Specifies an array of additional 32-bit data. Not currently used.
