Abstract: A set-top media system is disclosed which can be combined with an open architecture personal computer (PC) to provide a feature-rich secure integrated media center while meeting security rules of most major conditional access and content protection industry rules such as Cable Labs DFAST and PHILA agreements; and DTLA agreements for 5C-DTCP for IEEE1394, USB, and IP. The set-top media center and PC share common resources such as high definition display, remote control, hard disk drive, and other external unsecure storage devices. All media content is available seamlessly using a PC user interface, including controlled-content media such as high definition TV, within a PC desktop window. All controlled-content media is manipulated and managed within the set-top media system in a seamless manner. A mechanism is disclosed to allow controlled-content media to be stored on unsecure devices in encrypted form while overcoming the disk cloning attack problem for move operations.

Abstract: In an apparatus for intermittently advancing a web, only one surface of the web contacts moving parts of the apparatus. The apparatus includes, in a direction of movement of the web, a device for supplying the web, a first dancer roller arrangement, an intermittently driven drive roller, a second dancer roller arrangement, and a take-up device. The first and second dancer roller arrangements function to isolate a portion of the web from inertia in other portions of the web, and to provide substantially constant tension on opposite sides of the drive roller to prevent slippage and ensure accurate intermittent advancement of the web by the drive roller. A method for intermittently advancing a web is also disclosed.
