<2> Section 2.1: Transport mechanism is implemented in Windows 2000, Windows XP operating system Service Pack 2 (SP2), Windows Server 2003, Windows Vista, and Windows Server 2008. The WMDRM: License Protocol uses HTTP or HTTPS for data transfer, depending on the license acquisition URL specified in the WMRMHEADER object. The TCP ports are configurable by the implementer.

<3> Section The normal sequence of operations that the web page script takes in order to store the license locally is as follows:

  1. Create an IWMDRMProvider instance via WMDRMCreateProvider or WMDRMCreateProtectedProvider.

  2. Create an IWMDRMLicenseManagement instance by calling IWMDRMProvider::CreateInstance, passing in the IID of IWMDRMLicenseManagement.

  3. Call IWMDRMLicenseManagement::StoreLicense to store the license locally.

<4> Section The value of the predefined script variable "app.count" is 2 if the client application uses the Windows Media Digital Rights Management (WMDRM) SDK or 1 if an application uses DRM directly.
