摘要： A telecommunications platform comprises an antenna configured to generate a plurality of communications beams within a respective footprint on the surface of the Earth, wherein each communications beam provides data communications services over a respective cell coverage area on the surface of the Earth. The telecommunications platform further comprises a processor configured to control the plurality of communications beams of the antenna to form the respective cell coverage areas in a fixed cell pattern that remains essentially fixed relative to the surface of the Earth, such that, as the telecommunications platform travels through an orbit around the Earth, the footprint of the antenna sweeps across the fixed cell pattern and provides the communications services via the cell coverage areas of the fixed cell pattern that are within the footprint of the antenna at any given point in time.

摘要： Approaches for staged data compression are provided, where each stage reflects a progressive increase in granularity, resulting in a scalable approach that exhibits improved efficiency and compression performance. The first stage comprises a long-range block-level compressor that determines redundancies on a block-level basis (based on entire data blocks, as opposed to partial segments within data blocks). The second stage comprises a long-range byte-level compressor that compresses an uncompressed block based on byte segments within the block that match previously transmitted segments. The duplicate segments are replaced with pointers to matching segments within a decompressor cache. Nonmatching segments of the data block are left uncompressed and passed to a third stage short-range compressor (e.g., a grammar-based compressor). The staged progression in granularity provides advantages of maximizing the compression gain while minimizing processing and storage requirements of the compressor and decompressor.

摘要： Aspects of the invention provide a system and method to allow inroute frame timing synchronization without the aid of hub signal loopback or satellite ephemeris data. Furthermore, it allows tracking and compensating of the satellite motion to allow multiple remotes to use TDMA on the inroute frequencies, while minimizing the aperture. Two main techniques proposed are CLT and polling based approaches, which are used in combination for an optimum solution. In CLT based approach, hub transmits remote specific timing correction feedback messages on the outroute on as needed basis. In polling based approach, the remotes derive their timing based on a per-beam average delay estimate broadcast by the hub and a measured local delay specific to each outroute stream from a remote. An aspect of the invention uses triangulation method to determine satellite position. Furthermore, an aspect of the invention uses hub burst arrival method instead of polling approach.
摘要翻译：本发明的方面提供了一种系统和方法，其允许在无需集线器信号环回或卫星星历数据的帮助下进行帧定时同步。此外，它允许跟踪和补偿卫星运动，以允许多个遥控器在最小化孔径的同时使用TDMA在路由频率上。提出的两个主要技术是基于CLT和轮询的方法，它们被组合用于最佳解决方案。在基于CLT的方法中，集线器根据需要在远端传输远程特定定时校正反馈消息。在基于轮询的方法中，遥控器基于由集线器广播的每个波束的平均延迟估计和来自远程的每个外向流特定的测量的本地延迟导出其定时。本发明的一个方面使用三角测量方法来确定卫星位置。此外，本发明的一个方面使用集线器突发到达方法而不是轮询方法。

摘要： An approach for multi-stream data compression comprises receiving packets of a data stream, wherein the packets comprise respective packets of source data streams compressed on an aggregate basis and in a successive order. A one of the packets is decompressed, and a determination is made whether the packet has been received in a proper order of succession compared to the successive order of compression. When it is determined that the packet has been received in the proper order, the packet is stored at a next location in a decompressor cache. When it is determined that the packet has not been received in the proper order, the packet is stored at a location in the decompressor cache, allowing for subsequent storage of one or more further packets in the proper order of succession, wherein the further packets were processed via the compression process before, but were received after, the one packet.

摘要： An apparatus and method are disclosed for mitigating pointing errors resulting from satellite antennas. Reports are received from terminals in a beam hopping satellite communication system, and a pointing error associated with a satellite antenna is determined. The best beam for communicating with each terminal is selected based on the pointing error. A beam list containing the instantaneous traffic demand of terminals for each beam in the system is generated. An active beam set is then selected from the beam list for transmitting data during the next hop in the satellite communication system.

摘要： An approach for cached content identification for adaptive data streaming. A first request is received, requesting a current segment from a sequence of segments from a data file of a streaming data session. A NewVideoFlag is determined as indicating that the sequence of segments associated with the first request is not currently being cached. The first request is forwarded to a content server, and a first response message is received. A SegmentID of the received content segment is determined as not matching that of cached content segments. The NewVideoFlag is set to indicate that the segments from the streaming data session file are currently being cached. A global cVideoFileID is generated identifying the streaming session data file being cached. The content segment is cached, and cache bookkeeping is updated to associate the segment with the SegmentID and the cVideoFileID. The first response message is provided to the client device.
