  • Patent number: 6499106
    Abstract: A central access control system creates distribution CDs using an embedded data encryption process. A disc ID is also encrypted and recorded on each disc of each set of distribution CDs. The central access control system records the disc IDs and a remote location access rights list (ARL). A list of unique remote location IDs are also stored. The distribution CDs are delivered to one or more remote locations equipped with an information access system that includes its unique remote location ID, a CD reader with an embedded decryption system, and a communication link to the central access control system. The information access system can send the disc ID and its unique remote location ID as an access request to the central access control system. If the access control system is able to verify and grant the request, a unique decryption key will be sent to access the particular distribution CD currently contained in the information access system.

  • Patent number: 6481010
    Abstract: An integrated DSS/WebTV receiver is communicatively connected to an Internet service provider, a DSS service provider, and (optionally) a local broadcast station to provide a display of DSS programs, Internet web sites, and local broadcast channels in a seamless fashion. The DSS/WebTV receiver generates a graphical user interface (GUI), displayed on a television screen, for facilitating a user's navigation through the DSS, Internet, and local broadcast data. The GUI includes a TV Planner icon which, if selected by the user, causes the televison to display a monthly calender (or recording/reminder list) that indicates which programs are purchased and/or selected for recording by a VCR. A “Purchase” icon appears adjacent purchased programs and a “Record” icon appears adjacent programs to be recorded. If the user selects “Purchase” icon, the user is visually presented (e.g., via a pull-down screen) with the cost, date, and time of the program purchased or to be purchased.
