An airborne cell phone in-flight entertainment (IFE) system uses a cell phone for calls and IFE requests by dialing appropriate numbers. A pico cell receives the calls and the IFE requests. A soft switch switches the calls and IFE requests according to the telephone number. A transceiver receives the calls from the soft switch and sends them to a ground station that directs them to a telephone system. A media server receives IFE requests and provides IFE to the cell phone. A direct broadcast satellite (DBS) receiver on the aircraft receives DBS signals. A transcoder converts the received DBS signals from one compressed video format to another. A broad-to-connection protocol conversion process receives converted format DBS signals and converts them to video content blocks, stores the video content blocks to a continuously updated buffer and presents them to the media server and then to the cell phone.

A system and method is disclosed for providing a reverse channel to enable interactive communication between a DBS subscriber and DBS service provider. The addition of an interactive return channel overcomes the problems associated with existing audience measurement systems as well as the problems associated with existing DBS signal security techniques.

Program materials received from a direct broadcast satellite system are distributed between a host receiver and a client receiver for remote decryption. Using either a same pairing key or different host and client pairing keys, an encrypted media encryption key is received at both the host and client receivers, and the encrypted media encryption key is decrypted at both the host and client receivers using the pairing key. Encrypted program materials are received from the broadcast system at the host receiver, and the encrypted program materials are decrypted at the host receiver using the media encryption key. The encrypted program materials are also transferred from the host receiver to the client receiver, where the encrypted program materials are decrypted at the client receiver using the media encryption key.

Systems and methods are described for authorizing access to network service based upon information obtained from a set-top box (STB) or other subscriber equipment associated with the user requesting access to the network service. The network service suitably contacts a subscriber device associated with the user via the network in response to a request for access that is received from the user. Information obtained from the subscriber device is processed to thereby determine if the user is authorized to use the service. If the user is authorized, then the service is provided via the network. Access to an online video stream, for example, can be conditioned upon the requesting user having an appropriate account with a cable, direct broadcast satellite (DBS) or other service that can be verified through contact with the user's STB or other subscriber equipment.

A direct broadcast satellite (DBS) reception assembly may comprise an integrated circuit that is configurable between or among a plurality of configurations based on content requested by client devices served by the DBS reception assembly.

In a second configuration, the satellite frequency bands may be digitized by the integrated circuit as a plurality of separate narrowband signals. The integrated circuit may comprise a plurality of receive paths, each of the receive chains comprising a respective one of a plurality of low noise amplifiers and a plurality of analog-to-digital converters.
