Full title and description
Information technology — High efficiency coding and media delivery in heterogeneous environments — Part 10: MPEG Media Transport forward error correction (FEC) codes. This part of ISO/IEC 23008 specifies application-level FEC algorithms and code points to be used with the AL‑FEC framework of ISO/IEC 23008‑1 (MPEG Media Transport) to enable reliable delivery over packet-loss-prone IP and non‑IP networks.
Abstract
Specifies systematic application-level forward error correction (FEC) codes and their code points for use with MMT AL‑FEC. The document defines multiple FEC algorithms (including Reed‑Solomon, structured LDPC, RaptorQ variants and others), the encoding/repair symbol model and the mapping to MMT fields required for interoperable, resilient delivery of media over heterogeneous networks.
General information
- Status: Published (International Standard, confirmed).
- Publication date: April 2015 (first edition published April 2015; amendment for window‑based FEC issued 2021).
- Publisher: ISO/IEC JTC 1/SC 29 (joint ISO/IEC publication).
- ICS / categories: 35.040.40 (Coding of audio, video, multimedia and hypermedia information).
- Edition / version: Edition 1 (2015). Amendment 1: 2021 (Window‑based FEC code).
- Number of pages: 28 (main publication).
Scope
Defines the application‑level FEC codes and associated code points that can be used within the AL‑FEC framework of ISO/IEC 23008‑1 (MMT) to produce repair symbols from source symbol blocks and thereby improve packet‑loss resilience for media delivery across IP and non‑IP transport environments. The standard specifies the input/output symbol model, normative algorithmic descriptions for each FEC type, and how to signal the selected code in MMT repair flows.
Key topics and requirements
- Definition of FEC code points used by MMT AL‑FEC (mapping table of code identifiers to algorithms).
- Normative specifications for several systematic FEC algorithms: Reed‑Solomon (RS) codes.
- Normative specifications for Structured LDPC (S‑LDPC) codes and related parameters.
- Support and specification for RFC 6330 RaptorQ and a layer‑aware RaptorQ variant (RaptorQ LA), including use cases for object delivery.
- Specification of FireFort/LDGM‑style codes and optional compatibility with SMPTE ST 2022‑1 FEC algorithms.
- Requirements on symbol sizes, source/repair symbol block structure (K and P parameters), and Big‑Endian numeric conventions.
- Guidance for signaling fec_code_id_for_repair_flow within ISO/IEC 23008‑1 MMT messages to ensure interoperable selection of FEC algorithms.
Typical use and users
Implemented by MMT stack developers, streaming and broadcast equipment vendors, CDN and OTT service engineers, and application developers who require application‑level FEC for robust media delivery (especially for live streaming, contribution links, and delivery over lossy packet networks). It is used where an interoperable selection of FEC algorithms and signalling is needed between senders and receivers in heterogeneous delivery environments.

FAQ
Q: What is this standard?
A: ISO/IEC 23008‑10:2015 is the part of the MPEG‑H (ISO/IEC 23008) suite that defines application‑level forward error correction (FEC) algorithms and code points for use with MPEG Media Transport (MMT) AL‑FEC to support reliable media delivery.
Q: What does it cover?
A: It covers the normative algorithmic descriptions of multiple systematic FEC codes (e.g., Reed‑Solomon, structured LDPC, RaptorQ variants, LDGM variants and SMPTE 2022‑1 compatibility), their code point assignments, symbol/block modelling (K/P/T parameters), and how to signal the chosen FEC in MMT repair flows.
Q: Who typically uses it?
A: Implementers of MMT stacks, device and encoder/decoder vendors, CDN/OTT and broadcaster engineers, and developers of streaming applications who require interoperable FEC signalling and algorithms for packet‑loss resilience.
Q: Is it current or superseded?
A: The core document was published in April 2015 (Edition 1) and remains a published International Standard; an amendment (Window‑based FEC code) was published in 2021. Users should check national/adopter catalogues for regional reissues or withdrawals, but ISO lists the document as published/confirmed with the 2021 amendment available.
Q: Is it part of a series?
