D3D11_KEY_EXCHANGE_HW_PROTECTION_OUTPUT_DATA structure (d3d11_1.h)
Represents key exchange output data for hardware content protection.
Syntax
typedef struct D3D11_KEY_EXCHANGE_HW_PROTECTION_OUTPUT_DATA {
UINT PrivateDataSize;
UINT MaxHWProtectionDataSize;
UINT HWProtectionDataSize;
UINT64 TransportTime;
UINT64 ExecutionTime;
BYTE pbOutput[4];
} D3D11_KEY_EXCHANGE_HW_PROTECTION_OUTPUT_DATA;
Members
PrivateDataSize
The size of the private data reserved for IHV usage. This size is determined from the pPrivateOutputSize parameter returned by the ID3D11VideoDevice1::GetCryptoSessionPrivateDataSize function.
MaxHWProtectionDataSize
The maximum size of data that the driver can return in the output buffer. The last byte that it can write to is pbOutput[PrivateDataSize + MaxHWProtectionDataSize – 1].
HWProtectionDataSize
The size of the output data written by the driver.
TransportTime
The number of 100 nanosecond units spent transporting the data.
ExecutionTime
The number of 100 nanosecond units spent executing the content protection command.
pbOutput[4]
If PrivateDataSize is greater than 0, pbInput[0] – pbOutput[PrivateDataSize - 1] is reserved for IHV use.
pbOutput[PrivateDataSize] – pbOutput[HWProtectionDataSize + PrivateDataSize - 1] contains the input data for the DRM command. The format and size of the DRM command is defined by the DRM specification.
