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.

Reserved
