Patent
CA 2557110
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 novel 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. One embodiment utilizes a "grey list" of available programs to keep track of controlled-content media which is allowed to be played, while another embodiment utilizes a "black list" of programs no longer available to keep track of controlled-content media which is forbidden from being played.
