Full title and description

ISO/IEC 23000-11:2009/Amd 2:2011 — Information technology — Multimedia application format (MPEG-A) — Part 11: Stereoscopic video application format — Amendment 2: Signalling of additional composition type and profiles. This amendment updates the stereoscopic video application format (MPEG-A Part 11) by adding signalling for additional composition types and profiles used to describe 3D/stereoscopic composition arrangements in ISO base media file format-based files.

Abstract

This document is Amendment 2 to ISO/IEC 23000-11:2009 (MPEG‑A Part 11). ISO/IEC 23000-11 defines a file format and metadata for storage, interchange, editing and presentation of stereoscopic (3D) video content based on the ISO base media file format. Amendment 2 (published November 2011) introduces additional signalling to identify new composition types and profile identifiers so that players and devices can recognise and correctly present a wider range of stereoscopic composition arrangements.

Scope

This amendment applies to ISO/IEC 23000-11:2009 and specifies additional signalling elements (composition-type and profile identifiers) for stereoscopic video application format files. Its scope is limited to defining how additional composition types and presentation profiles are signalled in files following the MPEG‑A Part 11 rules so that existing players and file processors can detect and correctly handle these compositions and profiles.

Key topics and requirements

• Signalling of additional stereoscopic composition types (new composition-type values) to represent different 3D layout and rendering arrangements.
• Definition of additional profile identifiers to indicate profile-level constraints for stereoscopic content.
• Requirements for embedding the new signalling into ISO base media file format structures used by MPEG‑A Part 11 files.
• Clarification of metadata fields used to indicate visual type and stereo/mono fragment identification (stereo_mono_change information) when mixed content is present.
• Backwards-compatible signalling so existing conformant implementations can ignore unknown composition/profile identifiers or handle them gracefully when not supported.

Typical use and users

Implementers of multimedia file-packaging and playback software (players, encoders, packagers), device manufacturers (mobile devices, set-top boxes, 3D displays), content creators and distributors producing stereoscopic video packages, test and conformance laboratories, and standards professionals working on MPEG-A and ISO base media file format interoperability.

Related standards

ISO/IEC 23000 series (MPEG‑A) — particularly ISO/IEC 23000-11:2009 (base stereoscopic video application format) and its other amendments (Amendment 1 and Amendment 3). Also closely related: ISO base media file format (ISO/IEC 14496-12) and other ISO/IEC JTC 1/SC 29 (MPEG) specifications that define codecs, carriage and profile/profile-signalling used within MPEG-A application formats. Relevant MPEG-A parts (Part 1 Purpose, Part 19 CMAF, etc.) provide broader context for application-format packaging and profiles.

FAQ

Q: What is this standard?

A: This document is Amendment 2 (2011) to ISO/IEC 23000-11:2009, the MPEG‑A Part 11 stereoscopic video application format. It adds signalling for additional composition types and profiles used to describe stereoscopic content in ISO base media file format-based packages.

Q: What does it cover?

A: It specifies how to signal new composition-type values and profile identifiers inside MPEG‑A Part 11 files so players and processing tools can recognise and handle additional stereoscopic composition arrangements and profile constraints.

Q: Who typically uses it?

A: Developers and integrators of media packagers, players, encoders and device firmware that need to create, detect or present stereoscopic (3D) content packaged according to MPEG‑A Part 11; also content producers and standards/conformance testers.

Q: Is it current or superseded?

A: Amendment 2 was published on 7 November 2011 and is a published amendment to ISO/IEC 23000-11:2009. It remains part of the normative record for that part. ISO/IEC 23000-11 has had additional amendments (for example Amendment 3 in 2014) and the MPEG‑A family has continued development; users should check the ISO/IEC catalogue or their national standards body for the latest status or any subsequent revisions.

Q: Is it part of a series?

A: Yes — it is part of the ISO/IEC 23000 (MPEG‑A) series of Multimedia Application Format standards; specifically it is Amendment 2 to Part 11 (Stereoscopic Video Application Format).

Q: What are the key keywords?

A: stereoscopic, 3D, MPEG‑A, ISO base media file format, composition type, profile, amendment, packaging, stereo_mono_change.
