Any user-mode component that loads into the PMP PE and has access to unencrypted protected content that flows through a Windows Vista PC system to a final destination, such as a monitor.
protected content
Any content that is protected by some form of DRM.
premium content
Next-generation media content such as an HD DVD and other formats that are protected under the AACS standard.
Protected Environment (PE)
The protected execution environment in which PMP components run.
Protected Media Path (PMP)
An umbrella term for the collection of platform technologies that provide robust, interoperable premium audio-visual content processing on Windows Vista. PMP is a platform for sourcing, sinking, and manipulating protected media content in Windows Vista and beyond. Technologies that constitute the Protected Media Path include Protected Video Path (PVP), Protected User-Mode Audio (PUMA), and the PE. The PMP runs inside the PE.
Protected User-Mode Audio (PUMA)
The new User-Mode Audio (UMA) engine in the PE. It provides a safer environment for audio playback and checks that the enabled outputs are consistent with what the premium content provider allows. PUMA-compliant code is identified to the system through the DRM attribute.
Protected Video Path (PVP)
An umbrella term for the protection mechanisms that operate within the Windows Vista PE to ensure that the various video outputs from the PC—such as Digital Video Interface (DVI), video graphics array (VGA), and TV-out—are properly controlled or protected in accordance with the content’s policy. PVP components include PVP-OPM and PVP‑UAB.
protected video path-output protection management (PVP_OPM)
A component that ensures that the PC's video outputs have the required protection or that they are turned off if such protection is not available.
PVP-OPM Legacy Mode Certificate
A certificate that replaces the Windows XP Certified Output Protection Protocol (COPP) certificate. From an engineering standpoint, this is a COPP format certificate. It is intended for use on Windows Vista only to allow COPP legacy applications to function.
protected video path-user accessible bus (PVP_UAB)
A component that provides encryption of premium content as it passes over the PCI Express (PCIe) bus to the graphics adapter
Secure Audio Path (SAP)
The mechanism introduced in Microsoft Windows XP to protect audio content rendering. Windows Vista replaces SAP with PUMA. SAP-compliant code is identified to the system through the DRM attribute.
