This document describes the Windows Media Digital Rights Management for Network Devices (WMDRM-ND): Registrar Initiation Protocol, also known as DRMRI. This protocol is a set of services provided by a host (for example, a personal computer) and a client (for example, an extender device). These services allow a WMDRM-ND registration and authentication process to be remotely initiated and completed between the host and the client. The end result of this process is that DRM-protected content stored on the personal computer can ultimately be shared securely with the remote extender device. This protocol uses the Device Services Lightweight Remoting Protocol (DSLR) [MS-DSLR] to enable the remote initiation of the WMDRM-ND registrar process.
Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
