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.
Claims20
A system comprising
- a transmitter station comprising:
- a processor to select an error correction parameter based on an error correction configuration for a file, and
- an error correction circuit to encode the file based on the selected error correction parameter.
A method of error correction for a signal, comprising:
- selecting a tornado error correction parameter based on a representative parameter for the signal, the representative parameter comprising a desired error correction characteristic;
- encoding the signal using the tornado error correction parameter;
- and
- transmitting the encoded signal.
A system for reducing errors in received signals, comprising:
- a memory for storing a plurality of error correction factors;
- a processing device, coupled to the memory, for processing the received signals to determine an error correction factor used to encode the received signals and for retrieving the determined error correction factor from the plurality of error correction factors stored in the memory;
- and
- an error correction circuit, coupled to the processing device, for decoding the received signals using on the determined error correction factor.
