Full title and description

ISO/IEC 14496-1:2010/Amd 2:2014 — Information technology — Coding of audio-visual objects — Part 1: Systems — Amendment 2: Support for raw audio-visual data. This amendment adds support mechanisms in MPEG‑4 Systems for carrying raw (uncompressed or lightly encapsulated) audio and video data, including new ObjectTypeIndication values, DecoderSpecificInfo entries and Access Unit definitions for RawVideo and RawAudio streams.

Abstract

This short amendment (Amendment 2 to ISO/IEC 14496-1:2010) defines how raw audio and raw video streams can be represented within the MPEG‑4 Systems framework. It updates descriptor and stream-type tables, allocates identifier ranges for the Registration Authority, and specifies ObjectTypeIndication, DecoderSpecificInfo and Access Unit semantics required to carry raw audiovisual content alongside existing MPEG‑4 stream types.

Scope

This amendment applies to ISO/IEC 14496-1:2010 (MPEG‑4 Systems). It specifies the necessary additions and table updates to allow MPEG‑4 Systems to identify, describe and carry raw audiovisual data streams (RawVideo and RawAudio), to change registration ranges for ObjectType and command tags, and to reference LASeR and SAF stream codes where relevant. The amendment is intended to be read together with the base Part 1 text and related MPEG‑4 parts that define stream semantics.

Key topics and requirements

• Defines ObjectTypeIndication, DecoderSpecificInfo and Access Unit formats for RawVideo and RawAudio so raw data can be referenced and signalled in MPEG‑4 Systems.
• Updates stream-type and descriptor table allocations (reassigns ranges for the Registration Authority and for ISO use).
• Adds explicit stream identifiers for LASeR, SAF, Raw video stream and Raw audio stream in the stream-type table.
• Specifies minimal metadata and signalling needed for interoperability when transporting raw (uncompressed or container-encapsulated) audio/video in MPEG‑4 delivery and file formats.
• Is a concise technical amendment (3 pages) intended to be integrated with the main Part 1 Systems specification rather than to stand alone.

Typical use and users

Implementers of MPEG‑4 Systems (demuxers, muxers, packagers), codec and container developers, streaming platform engineers, media playback and authoring tool vendors, standards committees and researchers who need to transport raw audiovisual streams within MPEG‑4-based containers or sessions. It is primarily of interest to those who require explicit, standards-based signalling for non‑encoded (raw) or externally encoded audiovisual data inside MPEG‑4 delivery frameworks.

The amendment is part of the broader MPEG‑4 suite maintained by ISO/IEC JTC 1/SC 29.

FAQ

Q: What is this standard?

A: It is Amendment 2 (2014) to ISO/IEC 14496-1:2010 (MPEG‑4 Part 1 — Systems), titled "Support for raw audio‑visual data", formally published as ISO/IEC 14496-1:2010/Amd 2:2014.

Q: What does it cover?

A: The amendment specifies how to signal and carry raw (uncompressed or lightly encapsulated) audio and video within MPEG‑4 Systems. It adds ObjectTypeIndication and DecoderSpecificInfo entries and defines Access Unit semantics for RawVideo and RawAudio, and updates relevant tables (stream types, registration ranges, command tag allocations).

Q: Who typically uses it?

A: Media system and container implementers, streaming and playback vendors, codec developers and standards bodies that need a standard method to include raw audiovisual streams in MPEG‑4 based containers or streaming sessions.

Q: Is it current or superseded?

A: The amendment is a published update to the 2010 edition of Part 1. As of its publication in January 2014 it was a current amendment to the 2010 edition; readers should check the latest status of ISO/IEC 14496-1 (including any later editions or revisions) for the most up-to-date normative text.

Q: Is it part of a series?

A: Yes — it is part of the ISO/IEC 14496 series (MPEG‑4). This amendment specifically modifies Part 1 (Systems) and is intended to be used alongside other parts of the MPEG‑4 suite and referenced documents such as ISO/IEC 14496-20:2008 for LASeR/SAF stream definitions.

Q: What are the key keywords?

A: MPEG‑4, Systems, raw video, raw audio, ObjectTypeIndication, DecoderSpecificInfo, Access Unit, amendment, LASeR, SAF, registration authority.
