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.
