Simple Low-Density Parity Check Staircase Forward Error Correction Scheme for FECFRAME
RFC 6816, “Simple Low-Density Parity Check Staircase Forward Error Correction Scheme for FECFRAME”, is a Proposed Standard document published in December 2012 by V. Roca, M. Cunche, J. Lacan. The canonical text is published by the RFC Editor.
Abstract
This document describes a fully specified simple Forward Error Correction (FEC) scheme for Low-Density Parity Check (LDPC) Staircase codes that can be used to protect media streams along the lines defined by FECFRAME. These codes have many interesting properties: they are systematic codes, they perform close to ideal codes in many use-cases, and they also feature very high encoding and decoding throughputs. LDPC-Staircase codes are therefore a good solution to protect a single high bitrate source flow or to protect globally several mid-rate flows within a single FECFRAME instance. They are also a good solution whenever the processing load of a software encoder or decoder must be kept to a minimum.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
