DXVA_COPPStatusSignalingCmdData structure (dxva9typ.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Contains the result from a Signaling query in Certified Output Protection Protocol (COPP).

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[4]
Array of bit masks indicating which bits in ExtendedInfoData are valid.
ExtendedInfoData[4]
Additional signaling elements. This array is currently not used.
