It recently came to light that Sony Computer Entertainment received a U.S. patent exactly one year before on a one-system-one-disc technology that renders movie or game discs useless on more than one playback unit. If implemented, the technology would prevent affected discs from being rented or resold.
The patent describes a process by which every media disc is shipped with a unique registration key. The first time the media disc is inserted into a player, that key is read and the disc is registered by the player, then the original key on the disc is rendered unreadable. Any attempt to play a registered disc in another player will fail.
Are consumers going to take this? Will this be the DRM device that will piss people off enough to start doing something about it?
