DXVA_COPPSetSignalingCmdData 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 information for the Set Signal command in Certified Output Protection Protocol (COPP).

This command causes the driver to insert Wide Screen Signalling (WSS) codes or other data packets in the television signal, as required by some Analog Copy Protection (ACP) and Copy Generation Management System — Analog (CGMS-A) specifications. For example:

  • ETSI EN 300 294 (625i PAL): Data packets are inserted into line 23 of the signal.
  • CEA-608-B (NTSC): Data packets are inserted into line 21 of the vertical blanking interval (VBI).

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 from AspectRatioData1 to set in the signal.

AspectRatioData1

Specifies the aspect ratio value to be set for the current protection standard. For EN 300 294, use the COPP_ImageAspectRatio_EN300294 enumeration.

AspectRatioChangeMask2

Bit mask indicating which bits from AspectRatioData2 to set in the signal.

AspectRatioData2

An additional data element related to aspect ratio. The presence and meaning of this data depends on the protection standard. This field can 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 from AspectRatioData3 to set in the signal.

AspectRatioData3

An 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[4]

Array of bit masks indicating which bits in ExtendedInfoData to change. This array is currently not used. Set each member to zero.

ExtendedInfoData[4]

Additional signaling elements to be set. This array is currently not used. Set each member to zero.

Reserved

Reserved. Set to zero.
