PVP-OPM And Longhorn DRM
Posted by Suhit Gupta in "ARTICLE" @ 01:00 PM
"In Longhorn, Microsoft plans to introduce PVP-OPM (Protected Video Path-Output Protection Management), which is incompatible with most monitors sold today. Engadget's explanation of what Longhorn's PVP-OPM is reasonable: "What will happen when you try to play premium content on your incompatible monitor? If you’re 'lucky,' the content will go through a resolution constrictor." If "unlucky," the screen will be black. "The purpose of this constrictor is to down-sample high-resolution content to below a certain number of pixels. The newly down-sampled content is then blown back up to match the resolution of your monitor. This is much like when you shrink a JPEG and then zoom into it. Much of the clarity is lost. The result is a picture far fuzzier than it need be."
In order to create some sort of protection for premium content, the folks over at Microsoft have put this process in place. The top objective for these mechanisms is to enable the Windows-based PC to play premium content in 2006 and beyond, offsetting any content-owners fears that high-value content could be pirated if played on a PC.
