摘要： Rain fade mitigation methods and data broadcast systems that provide improved performance in a rain fade environment. The systems distribute data derived from a transmitting processor by way of a data distribution system to one or more receivers located at remote locations. The transmitting processor may include forward error correction processing software that is used to add forward error correction bits to data packets to be transmitted. When error correction bits are added to the data prior to transmission, the receivers include forward error correction software that processes the received data packets to reconstruct the original data. Data packets with or without error correcting bits may be transmitted two times to the remote locations, which times are separated by a time delay having a duration that is related to a rain fade event, which time delay is sufficient to allow data reconstruction in the presence of the rain fade event. The data packets may also be transmitted to the remote locations at a relatively slow transmission rate such that the time required to transmit the data to the one or more remote locations is greater than or equal to the time necessary to transmit the data plus the amount of time equal to an average rain fade event. The data packets are received at the remote locations and appropriately processed to reconstruct the original data.

摘要： Systems and methods for transferring very large data files to a remote location. The systems and methods fragment the very large data file into smaller ordered blocks using file conversion software loaded onto a computer processor. The ordered fragmented files or blocks transmitted to the remote location using a data distribution system. For example, the data distribution system may include a transmitter, a satellite transmission link, and a receiver at each remote location. At each remote location, received ordered fragmented files or blocks are reassembled in accordance with the original ordering scheme using file conversion software loaded on a computer. This produces the original very large data file. Once the very large data file is reassembled, it may be processed or archived.

摘要： A method and apparatus for communicating between information service provider systems (ISPS) and customer premise equipment (CPE) is provided. The method includes the steps of: (a) transmitting a request for information from a requesting CPE on the upstream communication path, the request including a type of information; (b) based upon the type of information requested, routing the request to a selected ISPS coupled upstream and a selected ISPS coupled downstream; (c) receiving the requested information from the selected ISPS coupled upstream and the request for information from the selected ISPS coupled downstream on the downstream communication path at an associated one of a plurality of cable distribution devices, wherein the associated cable distribution device serves the requesting CPE; (d) wherein when the associated cable distribution device receives the request, routing the request to and receiving the requested information from the selected ISPS coupled downstream; (e) forming a composite signal which includes the requested information from the selected ISPS coupled upstream and the selected ISPS coupled downstream; and (f) distributing the composite signal on the cable transmission channels of the downstream path from the associated cable distribution device to the requesting CPE.
