摘要： PROBLEM TO BE SOLVED: To provide a method for encoding, as chain reaction codes, data which is used in a data communication system at a high speed, security, and a small calculation cost.SOLUTION: The method for encoding the data as the chain reaction codes, comprises a step of generating a set of input signs from input data. Each non-systematic output sign is selected from among alphabets of the non-systematic output signs, and one or a plurality of the non-systematic output signs, which are generated as a function of one or a plurality of the input signs, are generated from the set of the input signs. As a result of this encoding process, an optional subset out of the set of the input signs can be recovered from (i) a predetermined number of the non-systematic output signs or (ii) a combination of (a) an input sign not included in a subset of the input signs to be recovered and (b) one or a plurality of the non-systematic output signs.

摘要： PROBLEM TO BE SOLVED: To provide a method of streaming for data transmission with an assumption that a receiver will begin using the data before it is all transmitted and received.SOLUTION: Streamed data includes forward error correction (FEC) and the rates of data consumption can vary. The transmitter has an input rate and a transmit rate and the two rates can be different and can change. At the receiver, there is a reception rate (at which the receiver receives data) and a consumption rate (at which the receiver uses up data for its output). The transmitter transmits using a transmit rate higher than the consumption rate and the extra bandwidth is usable for FEC protection and buffering.

摘要： PROBLEM TO BE SOLVED: To provide a simple error correcting code that does not require excessive operation capability or memory to a transmitter or a receiver. SOLUTION: For a given key, an output symbol is generated from a combined set of symbols including input symbols and redundant symbols. Each of the output symbols is independent, and a countless number of output symbols can be generated substantially in resolution of a key used according to need. The output symbols are information additive so that a received output symbol can provide additional information for decoding even when many symbols are already received. A decoder calculates check symbols from the output symbols received. Each check symbol is associated with one or more input symbols and redundant symbols. For each received output symbol, the decoder updates a running total of estimated information content and, in one or more rounds, generates a probability distribution for possible values of each input symbol over all or some of the input symbols.
