摘要： An encoder encodes an output symbol from input symbols of an input file by determining, for a given output symbol, a list AL that indicates W associated input symbols, within a subset S of the input symbols comprising the input file, to be associated with the output symbol, where W is a positive integer, where at least two output symbols have different values for W associated therewith, where W is greater than one for at least one output symbol, and where the number of possible output symbols is much larger than the number of input symbols in the input file, and generating an output symbol value from a predetermined function of the W associated input symbols indicated by AL. The subset S can be a window that slides over the input file to cover all of the input symbols in a period. The window can be a fixed or variable size. Where the window moves over the file and reaches an edge, the window can wrap around or can cover extended input symbols.

摘要： Multiple files a served using a server coupled to a data network. A plurality of files is determined, wherein a file includes an integer number of blocks, and wherein each block includes at least one input symbol. For each file, an indication of at least one channel on which to serve the file is determined, and, for each file, a rate at which to serve the file is determined. Also, a schedule for processing the blocks is determined, and output symbols for the blocks are generated according to the schedule. The output symbols are transmitted on the corresponding at least one channel, wherein the files are concurrently served at their corresponding rates.
