Abstract: Various arrangements are presented for optimizing data transmission between a satellite and a user equipment. A satellite gateway system may receive a message from the user equipment indicative of a current location of the user equipment. Data may be retrieved from the Internet to be transmitted to the user equipment via the satellite. The satellite gateway system may transmit a downlink message to the satellite that comprises the retrieved data and beam steering data. The beam steering data may instruct the satellite to target a downlink spot beam on the current location of the user equipment based on the message received from the user equipment. The retrieved data may be transmitted to the user equipment via the targeted downlink spot beam.

Abstract: Arrangements for optimizing bandwidth of a satellite communication link are presented. A first satellite gateway system may transmit a first data set to a satellite to be relayed by the satellite to a first instance of user equipment. A second satellite gateway system may transmit a second data set to the satellite to be relayed by the satellite to a second instance of user equipment. A satellite gateway management system may determine that the second satellite gateway system has greater available bandwidth. The satellite gateway management system may route a third data set to be transmitted to the first instance of user equipment to the second satellite gateway system. The second satellite gateway system may transmit the third data set and beam steering data to the satellite, such that the satellite targets a downlink spot beam on the first instance of user equipment.

Abstract: A method and apparatus for enabling background caching of encrypted programming data on a storage medium for later playback in a digital video recorder (DVR) system. A set-top box (STB) equipped with a DVR searches a program guide for upcoming pay-per-view (PPV) events. When the PPV event begins, the STB tunes an appropriate transponder and begins receiving programming data packets containing audio, video, system time and conditional access data packets associated with the event, which are stored for playback on a storage medium. When the user turns the STB on and selects an option to playback a previously-recorded PPV event, the appropriate programming data is retrieved from the storage medium, and the STB recreates the original transmission timing of the data, to be displayed on a display device of the user.

Abstract: A communication system including an upstream proxy server and two reporting downstream proxy servers, where the upstream proxy server is capable of multicasting a uniform resource locator (URL) to the reporting downstream proxy servers, the reporting downstream proxy servers interact with the upstream proxy server to resolve cache misses and the upstream proxy servers returns a resolution to a cache miss via multicast. A downstream proxy server which filters multicast transmissions of URLs and stores a subset of the URLs for subsequent transmission, where relative popularity is used to determine whether to store a multicast URL. An upstream proxy server capable of multicasting URLs to reporting downstream proxy servers, where the upstream proxy server interacts with the two reporting downstream proxy servers to resolve cache misses and the upstream proxy server returns a resolution to the cache misses via multicast.
