Abstract

This document describes two fully specified Forward ErasureCorrection (FEC) Schemes for Sliding Window Random Linear Codes(RLC), one for RLC over the Galois Field (a.k.a., Finite Field)GF(2), a second one for RLC over the Galois Field GF(2^8), each timewith the possibility of controlling the code density. They canprotect arbitrary media streams along the lines defined by FECFRAMEextended to Sliding Window FEC Codes. These Sliding Window FEC Codesrely on an encoding window that slides over the source symbols,generating new repair symbols whenever needed. Compared to block FECcodes, these Sliding Window FEC Codes offer key advantages withreal-time flows in terms of reduced FEC-related latency while oftenproviding improved packet erasure recovery capabilities.
