摘要： A method of encoding data for transmissions from a source to a destination over a communications channel is provided. The method operates on an ordered set of source symbols and may generate zero or more redundant symbols from the source symbols, wherein data is encoded in a first step according to a simple FEC code and in a second step, data is encoded according to a second FEC code, more complex than the first FEC code. The first FEC code and/or the second FEC code might comprise coding known in the art. These steps result in two groups of encoded data in such a way that a low complexity receiver may make use of one of the groups of encoded data while higher complexity receivers may make use of both groups of encoded data.

摘要： Transmitters and receivers deal with streams of data, wherein the receiver is expected to begin using received data before receiving all of the data. Concurrent streams are sent and FEC coding is used with the streams and done as an aggregate. The transmitter performs FEC operations over the plurality of streams, wherein source blocks from at least two streams logically associated into a jumbo source block and FEC processing is performed to generate one or more jumbo repair block from the jumbo source block. Each of the source blocks comprises one or more source symbols from their respective stream. The jumbo source symbols can be of constant size and are suitably aligned along size boundaries that make processing efficient. Each source symbol need not be the same size, and the number of source symbols from each stream in a jumbo source block need not be the same value across streams.

摘要： A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server, which might include a cache. A client device can be adapted to take advantage of the ingestion process as well as improvements that make for a better presentation independent of the ingestion process. The client devices and ingestion system can be coordinated to have a predefined mapping and template for making block requests to HTTP file names that a conventional file server can accept through the use of URL construction rules. Segment size might be specified in an approximate manner for more efficient organization.

摘要： A communication system wherein a transmitter transmits a media stream to a receiver encoded using FEC, comprising at least one hypothetical FEC decoder at the transmitter for decoding the media stream encoded at the transmitter. The transmitter determines what optimization signals to provide the receiver given the outputs of the at least one hypothetical FEC decoder and signals to the receiver those optimization signals. The optimization signals might include slowdown of media consumption signals, indications of variable buffering parameters and/or indications of FEC and source data ordering.

摘要： PROBLEM TO BE SOLVED: To provide a communication system for encoding and decoding data for efficiently utilizing communication data generated from sources more than one by analyzing an error and a gap in the communication data. SOLUTION: Lost transmission packets are recovered using parity symbols. An encoder uses a key I selected from a key alphabet to produce output symbols. An output symbol with the key I is generated by determining a weight W(I) for the output symbol to be generated, selecting a number W(I) of the output symbols associated with the output symbol according to a function of I, and generating the output symbol's value B(I) from a predetermined value function F(I) of the selected W(I) input symbols so that erasures can be recovered without grouping input symbols into one block. An encoder can be called repeatedly to generate multiple output symbols. COPYRIGHT: (C)2005,JPO&NCIPI
