TV One has announced several DVI products, all of them HDCP compliant.

One is a DVI repeater, ensuring long lengths of DVI cable can be run, up to 40′ or more. Up to three repeaters can be cascaded to reach your display into your neighbour’s back yard. TV One also announced distribution amplifiers for displaying one signal on multiple displays. And they also have switchers for one display to choose among several sources. HDCP information is kept through the switching process, so you don’t have to worry about your copy-protected material with these devices.
