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.

Claims

1. 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.
