HWProtectionDataSize
The size of the DRM command data.
pbInput[4]
If PrivateDataSize is greater than 0, pbInput[0] – pbInput[PrivateDataSize - 1] is reserved for IHV use.
pbInput[PrivateDataSize] – pbInput[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.
