Abstract
This document describes a fully-specified FEC scheme for the
Supercharged forward error correction code. Supercharged codes are
designed for use on the erasure channel. Coding for the erasure
channel commonly arises for data transmission over the internet, where
lower layers either successfully deliver packets or fail to deliver
them. Coding is required to insure that data is not lost, even if
packets are lost at the lower layers. Error free reception is
important for multimedia applications, such as streaming, where it may
not be possible to correct an error in time by any other means. Coding
insures that lost packets can be recovered.
