What is PAVP (Protected Audio Video Path)?
PAVP (Protected Audio Video Path) is a feature to ensure a robust and secure content protection path for high-definition video playback including Blu-ray discs on the Microsoft Windows Vista* operating system. PAVP ensures that computers supporting hardware-based decode acceleration are properly utilized in order to deliver smooth playback. In addition, PAVP reduces processor utilization by off-loading the video decode onto the chipset to free up the processor to perform other tasks.
