Abstract
Methods and apparatus to select Tornado forward error correction parameters for delivery systems are disclosed. A disclosed example system includes a transmitter station comprising a processor to select a Tornado error correction parameter based on an error correction configuration for a file and to indicate to a receiver the selected Tornado error correction parameter, and a Tornado error correction circuit to encode the file based on the selected Tornado error correction parameter.
Claims36
A system comprising
- a transmitter station comprising:
- a processor to select a Tornado error correction parameter based on an error correction configuration for a file, and to indicate to a receiver the selected Tornado error correction parameter;
- and
- a Tornado error correction circuit to encode the file based on the selected Tornado error correction parameter.
A method comprising:
- receiving a parameter representative of a desired error correction characteristic for a file;
- selecting a Tornado error correction parameter based on the representative parameter;
- encoding the file using the Tornado error correction parameter;
- and
- transmitting the encoded file to a receiver.
A method comprising:
- receiving a parameter representative of a selected Tornado error correction graph;
- receiving an encoded file;
- and
- decoding the encoded file based on the selected Tornado error correction graph.
An article of manufacture storing machine readable instructions which, when executed, cause a machine to:
- select a Tornado error correction graph based on a desired error correction characteristic;
- indicate the selected Tornado error correction graph to a receiver;
- encode a file using the selected Tornado error correction graph;
- and
- transmit the encoded file to the receiver.
An article of manufacture storing machine readable instructions which, when executed, cause a machine to:
- receive a Tornado error correction graph selection;
- receive an encoded file;
- and
- decode the encoded file based on the selected Tornado error correction graph.
An apparatus comprising:
- a processor to receive a parameter indicative of a selected Tornado error correction graph;
- a Tornado error correction circuit to decode received an encoded file based upon the selected Tornado error correction graph;
- a memory to store a plurality of Tornado error correction graphs, wherein the selected Tornado error correction graph is one of the plurality of Tornado error correction graphs.
