    摘要: Described herein are ways to reduce bandwidth use for real-time broadcasts between an Internet Service Provider (ISP) and its subscribers by re-encoding audiovisual data streams to have a generic encoding that can be viewed by subscribers of different content providers. A system can determine that a plurality of subscribers is watching the same live event and can multicast the generic encoding of the live event to the plurality of subscribers, even where individual subscribers stream the live event from different content providers. This can eliminate the need for streaming multiple versions of the same live event from different content providers to subscribers. The systems can generically encode an audiovisual data stream of a live event to generate a single audiovisual data stream for the live event that is multicast to subscribers watching the same live event.

    摘要: Described herein are ways to advantageously reduce bandwidth use between an internet service provider and its subscribers by re-encoding media objects to have a generic encoding that can be cached at subscriber devices. When a subscriber makes an authorized request for a media object from a content provider, a cached version of the generically encoded media object may be played by the subscriber even if the subscriber is not a customer of the content provider that originally provided the media object. This can eliminate the need for streaming a new copy of the media object from the content provider. The disclosed systems are configured to identify when differently-encoded media objects represent the same media object so that subscribers can play cached media objects rather than requiring each media object be streamed from different content providers.

    摘要: Methods, systems, and devices for providing communication sessions based on mobile application engagement. In some examples, a communication session delivery system may establish, by a multi-user access terminal on a transport vessel, a communication session with a personal electronic device of a passenger, the communication session restricted to a first domain. The communication session delivery system may present, one or more reward offers related to the communication session and receive an indication of selection of a first reward offer associated with engagement of an application for execution on the personal electronic device. The communication session delivery system may redirect the communication session to a second domain associated with installation of applications for the personal electronic device and restrict the communication session to the first domain, the second domain, and a third domain associated with an application server for the application based on redirecting the communication session to the second domain.

    摘要: Methods, systems, and devices for gimballess quasi-omni optical communication transceivers. A system may include a support structure having a surface and a set of optical transmitters perforating the surface. Additionally, the system may include an optical receiver, where the optical receiver includes a luminescence wavelength-converting fiber disposed on the surface of the support structure and a detector coupled with at least one end of the luminescence wavelength-converting fiber. In some examples the luminescence wavelength¬ converting fiber may be wrapped at least partially around the support structure and may be located between at least two pairs of the set of optical transmitters. The luminescence wavelength-converting fiber may be configured to absorb light at a first wavelength and emit light within a channel of the luminescence wavelength-converting fiber at a second wavelength and the detector may be configured to convert the light at the second wavelength to an electrical signal.

    摘要: According to techniques disclosed herein, a Tactical Data Link (TDL) terminal uses a first clock that runs during a sleep mode for initial realignment of a second clock that is used for synchronous operation with respect to a TDL network during active-mode operation of the TDL terminal. For example, implementation of the first clock via low-power circuitry and characterization of the relative error or drift of the first clock with respect to the second clock allows the TDL terminal to adjust the phase of the second clock upon transitioning back to active-mode operation, for accurate realignment of the second clock with the TDL network timing.

    摘要: A geosynchronous equatorial orbit (GEO) ground station may concurrently receive at a tracking receiver both a first signal (downlink data) at a first frequency from a GEO satellite and an internally-generated calibration signal at a second frequency.. Based on the calibration signal, the tracking receiver may determine a first phase value for the second frequency, then, from the first phase value, determine a second phase value associated with the first frequency based on a first phase offset between the first frequency and the second frequency according to a set of receiver calibration factors, then generate a phase correction value for signals received at the first frequency without interrupting the downlink data coming from the GEO satellite. Having accurate phasing allows the tracking receiver to report tracking errors correctly to the antenna controller and therefore allow for improved tracking performance.

    摘要: Systems and methods for communications satellites to switch operating modes are described. A communications satellite may operate according to a first operating mode to provide communications services for user terminals in a first coverage area (e.g., providing the user terminals with forward link communications services using a first communication link with a first polarization) The communications satellite may receive correspondingly polarized forward uplink signals from access node terminals in a second coverage area, and the communications satellite may relay respective forward downlink signals to the user terminals in the first coverage area. In some cases, the first coverage area may geographically overlap the second coverage area. The communications satellite may determine a second operating mode (e.g., to optimize the communications services based on dynamic conditions), and the communications satellite may switch to the second operating mode to provide communications services for the user terminals.

    摘要: Technology is described for providing electronic sponsor pages to passengers on an aircraft. An interface control and an inflight interactive environment may be combined at a server on the aircraft. The interface control may be associated with an electronic sponsor page and may enable a passenger on the aircraft to access the electronic sponsor page through the inflight interactive environment. The inflight interactive environment may be sent from the server to a client device onboard the aircraft over a network connection for display on the client device. A selection of the interface control included in the inflight interactive environment may be received. The electronic sponsor page may be sent from the server to the client device for display. The electronic sponsor page may include a sub-interface enabling access to one or more electronic objects.

    摘要: Methods, systems, and devices communications are described. A terminal may be identified with a geographic region. First beam coefficients may be determined for an antenna array having interelement spacing of antennas that is different across the antenna array. The first beam coefficients may be used to form a first beam for the terminal, where a coverage area of the first beam may encompass the geographic region. The first beam may be used to communicate with the terminal. Based on a utilization of the first beam exceeding a threshold, second beam coefficients may be determined for the antenna array. The second beam coefficients may be used to form a second beam, where a coverage area of the second beam may be different than the coverage area of the first beam. The second beam may be used to communicate with the terminal.
