Certified Output Protection Protocol (COPP)
Definition - What does Certified Output Protection Protocol (COPP) mean?
Techopedia explains Certified Output Protection Protocol (COPP)
While displaying a video, whether or not the user is aware of it, the process of COPP is applied to the user's activities to guard against improper or unauthorized video streaming. Microsoft first enlisted this protection protocol to protect against illegal recordings or distribution of videos. COPP provides copy-protection capabilities and has warranted the approval of companies such as CyberLink since 2005.
For instance, if a user is attempting to stream an audio and receives a pop-up containing “Access Denied,” there is a very high probability that there is an application working in conjunction with Microsoft’s COPP.
