Members

rApp

A 128-bit random number that was passed by the application in the AMCOPPStatusInput structure.

dwFlags

Status flag. See COPP_StatusFlags.

AvailableTVProtectionStandards

Bitwise OR of flags from the COPP_TVProtectionStandard enumeration. The driver should return flags for all of the protection standards and resolutions that it supports.

ActiveTVProtectionStandard

Member of the COPP_TVProtectionStandard enumeration, indicating the protection standard that is currently active.

TVType

Reserved.

AspectRatioValidMask1

Bit mask indicating which bits of AspectRatioData1 are valid.

AspectRatioData1

Specifies the current aspect ratio value. For EN 300 294, the value is a member of the COPP_ImageAspectRatio_EN300294 enumeration.

AspectRatioValidMask2

Bit mask indicating which bits of AspectRatioData2 are valid.

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.

AspectRatioValidMask3

Bit mask indicating which bits of AspectRatioData3 are valid.

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.

ExtendedInfoValidMask

Array of bit masks indicating which bits in ExtendedInfoData are valid.

ExtendedInfoData

Additional signaling elements. This array is currently not used.
