| 20080279386 | METHOD AND APPARATUS FOR ENCRYPTING MEDIA PROGRAMS FOR LATER PURCHASE AND VIEWING - A system and method for storing and retrieving program material for subsequent replay is disclosed. The method includes accepting a receiver ID associated with a receiver key stored in a memory of the receiver, determining a pairing key for encrypting communications between the conditional access module and the receiver, encrypting the pairing key with the receiver key, and transmitting a message comprising the encrypted pairing key to the receiver. The apparatus comprises a receiver for receiving a data stream transmitting a media program encrypted according to a media encryption key and an encrypted media encryption key and a conditional access module, communicatively coupleable with the receiver. | 11-13-2008 |
| 20090178069 | INTERNET SERVICE PROVIDER CALLBACK FOR SATELLITE SYSTEMS - A method, apparatus, article of manufacture, and a memory structure for delivering purchase information comprising storing purchase information for a purchase of a user in a set top box. The set top box (STB) is configured to receive and display the broadcast signals through a tuner onto a display device. The STB establishes a connection to the Internet through a user initiated action (e.g., when the user accesses the Internet using the STB). A new transmission control/Internet protocol (TCP/IP) connection is obtained using the established user-initiated Internet connection without the user requesting the connection. A secure electronic connection is established with a server through the new TCP/IP connection. The purchase information is then transmitted from the STB through the secure electronic connection to the server. | 07-09-2009 |
| 20100037254 | SYSTEM AND METHOD FOR MEDIA TRANSCODING AND PRESENTATION - A method and apparatus for presenting a media data stream complying with a broadcast encryption standard is disclosed. A dongle is removably coupleable to a rendering device, with the dongle performing transcoding so as to allow presentation of the media in a secure manner without modification of the rendering device software or hardware. | 02-11-2010 |
| 20100213974 | Method and apparatus for camouflaging a printed circuit board - A method, apparatus, article of manufacture, and a memory structure for camouflaging an application specific integrated circuit (ASIC), wherein the ASIC comprises a plurality of interconnected functional logic cells. In one embodiment, the method comprises the steps of identifying at least one gap between the plurality of interconnected functional logic cells having no functional logic therein, placing one filler cell or combination of filler cells into the identified gap and defining a routing of the placed filler cells. | 08-26-2010 |
| 20100301903 | BUILDING BLOCK FOR A SECURE CMOS LOGIC CELL LIBRARY - A logical building block and method of using the building block to design a logic cell library for CMOS (Complementary Metal Oxide Silicon) ASICs (Application Specific Integrated Circuits) is disclosed. Different logic gates, built with the same building block as described in this invention, will have the same schematics of transistor connection and also the same physical layout so that they appear to be physically identical under optical or electron microscopy. An ASIC designed from a library of such logic cells is strongly resistant to a reverse engineering attempt. | 12-02-2010 |
