摘要： A sequence of symbol operations (a “schedule representation”) within a data storage device, wherein the operations are those used to process encoding or decoding operations of a forward error correction code (an “FEC code”) upon an arbitrary block of data of a given size (where size can be measured in numbers of symbols). The method is such that the schedule representation can be used to direct the processing of these operations upon a block of data in a way that is computationally efficient. Preferably, the same method can be applied to represent schedules derived from multiple different algorithms for the encoding or decoding of a code or for multiple different codes.

摘要： A communications system can provide methods of dynamically interleaving streams, including methods for dynamically introducing greater amounts of interleaving as a stream is transmitted independently of any source block structure to spread out losses or errors in the channel over a much larger period of time within the original stream than if interleaving were not introduced, provide superior protection against packet loss or packet corruption when used with FEC coding, provide superior protection against network jitter, and allow content zapping time and the content transition time to be reduced to a minimum and minimal content transition times. Streams may be partitioned into sub-streams, delivering the sub-streams to receivers along different paths through a network and receiving concurrently different sub-streams at a receiver sent from potentially different servers. When used in conjunction with FEC encoding, the methods include delivering portions of an encoding of each source block from potentially different servers.

摘要： Data is streamed from a transmitter to a receiver, wherein streaming is transferring data with an assumption that the receiver will begin using the data before it is all transmitted and received and the 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. In some embodiments, the excess rate varies over a transmission period.

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： In a data decoder for decoding data from received symbols received over a channel from an encoder, a method for decoding data wherein the received data includes erasures and includes source symbols and repair symbols organized into one or more source blocks. The decoder uses a generator matrix, any square submatrix of which is invertible, such that the decoder performs decoding operations concurrently with the arrival of the source symbols and repair symbols that are a part of a source block. Novel methods for interleaving and specifying encoding structure for a large class of FEC codes, scheduling the sending of packets and the like, are also applied in conjunction with the method for decoding data.

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. A client device can be adapted to take advantage of the ingestion process. The client device might be configured to optimize use of resources, given the information available to it from the ingestion system. This may include configurations to determine the sequence, timing and construction of block requests based on monitoring buffer size and rate of change of buffer size, use of variable sized requests, mapping of block requests to underlying transport connections, flexible pipelining of requests, and/or use of whole file requests based on statistical considerations.

The method also includes generating a plurality of output symbols from a combined set of symbols including the input symbols and the redundant symbols based on linear combinations, wherein at least one of the linear constraints or combinations is over a first finite field and at least one other of the linear constraints or combinations is over a different second finite field, and such that the ordered set of input symbols can be regenerated to a desired degree of accuracy from any predetermined number of the output symbols.
