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： Signaling the sending of source blocks within multiple physical layer blocks is done for both streaming and object delivery applications, using minimal additional overhead, and in some cases no overhead, to signal interleaved source blocks within a physical layer block, signaling how symbols are related to the source blocks from which they are generated, and signaled sending and indications of prioritized data for source blocks. Organizing and sending streams over one more channels can be done to improve the quality of delivered streams, while minimizing or improving the needed amount of channel resources and receiver power resources needed.

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.

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： An encoder uses an input file of data and a key to produce a group of output symbols. A group of output symbols with key I is generated by determining a weight, W(I), for the group of output symbols to be generated, selecting W(I) of the input symbols associated with the group according to a function of I, and generating the output symbol values B(I) from a predetermined value function F(I) of the selected W(I) input symbols. An encoder can be called repeatedly to generate multiple groups of output symbols or multiple output symbols. The groups of output symbols are generally independent of each other, and an unbounded number (subject to the resolution of I) can be generated, if needed. A decoder receives some or all of the output symbols generated. The number of output symbols needed to decode an input file is equal to, or slightly greater than, the number of input symbols comprising the file, assuming that input symbols and output symbols represent the same number of bits of data.
