  • Patent number: 8671163
    Abstract: A method of serving content to multiple clients via a network is provided. Independent sessions with each of a plurality of clients are maintained, wherein the number of clients in the plurality of clients can vary over time, and wherein the start of each session and the end of each session can be independent of the start and end of other sessions. A stream of packet payloads is received, each packet payload of the stream of packet payloads including data generated from the content, wherein each packet payload in at least a subset of the stream of packet payloads includes a different set of data. Each packet payload in the stream of packet payloads is transmitted to each client of the plurality of clients in corresponding packets, wherein the packet payload transmitted to a client at any particular time is independent of the state of the corresponding session.

  • Patent number: 6486803
    Abstract: 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.

  • Patent number: 6411223
    Abstract: Output symbols are generated using input symbols and basis elements. A plurality of basis elements are generated. Each basis element is generated from a predetermined function of associated input symbols associated with the basis element. For each output symbol, a set of associated basis elements associated with the output symbol is determined, and a set of direct associated input symbols directly associated with the output symbol is determined. For each output symbol, the output symbol is generated from a predetermined function of the associated basis elements and the associated input symbols.
