Introduction to COPP

Introduction to COPP

This section applies only to Windows Server 2003 with SP1 and later, and Windows XP with SP2 and later.

COPP provides a mechanism of applying copy protection to video that is output by the graphics adapter. COPP provides a common protocol for sending various link-protection requirements to the graphics adapter in a more protected fashion than by using the IOCTL_VIDEO_HANDLE_VIDEOPARAMETERS I/O control (IOCTL) code.
