Intel has developed a new standard for device authentication and digital content encryption. It was developed specifically for encrypting uncompressed digital video on its way to a monitor (either a computer monitor or a television) specifically with DVI (digital video interface). It is, however, general enough to be used for other forms of digital information. The standard is availible from Digital Content Protection, LLC, a corporation formed to act as a holding company for the standard. My sources have told me that the MPAA has been pressuring the direct satellite services (DirecTV and the DishNetwork) to require that all movies be transmitted from the satellite set-top box to the monitor via DVI protected with HDCP. They believe it to be more secure than the existing high-definition analog connections. I respectfully must disagree.
