Overview

ISO/IEC 14496-4:2004/Amd 42:2014 is an important international standard published by ISO that addresses conformance testing for audio-visual coding technologies. This amendment specifically covers the Multi-Resolution Frame Compatible (MFC) Stereo Coding extension of the Advanced Video Coding (AVC) standard. It builds upon Part 4 of the MPEG-4 series, which focuses on conformance testing methods to ensure compliance with audio-visual coding specifications.

The document is vital for organizations and developers involved in the creation and testing of multicast stereo audio-visual content encoded using AVC technology with an MFC stereo extension. By defining rigorous conformance testing procedures, this standard helps maintain interoperability, quality, and reliability in multi-resolution stereo coding deployments.

Key Topics

• Conformance Testing for MFC Stereo Coding: The amendment outlines specific test methodologies essential for validating the compatibility and correct implementation of Multi-Resolution Frame Compatible Stereo Coding within AVC frameworks.

• Extension of AVC Standard: Focuses on the stereo coding extension to AVC, enabling enhanced audio-visual experience through sophisticated frame-compatible stereo multi-resolution techniques.

• Compliance Validation: Offers detailed guidelines on how to verify that encoders and decoders adhere strictly to the MFC stereo coding syntax and semantics, ensuring consistent playback quality.

• Electronic Documentation and Accessibility: The standard includes electronic attachments and is distributed in a user-friendly PDF format to facilitate implementation and reference by industry professionals.

Applications

ISO/IEC 14496-4:2004/Amd 42:2014 applies to a wide range of fields where advanced audio-visual encoding is critical:

• Broadcasting and Streaming Services: Ensuring stereo audio-visual streams conform to multi-resolution frame compatible coding for high-quality, scalable delivery across various networks.

• Multimedia Development: Guiding developers in creating AVC-based encoders and decoders that meet strict conformance requirements, leading to reliable product performance.

• Consumer Electronics: Supporting manufacturers of TVs, set-top boxes, and media players in integrating stereo coding extensions that improve user experience through compatibility.

• Quality Assurance and Testing Laboratories: Providing a framework to systematically test and certify AVC stereo coding products for market readiness.

Related Standards

This amendment complements and extends existing ISO/IEC standards related to multimedia coding and conformance testing, including:

• ISO/IEC 14496-4 (MPEG-4 Part 4): The base standard detailing the overall conformance testing process for audio-visual object coding.

• ISO/IEC 14496-10 (AVC/H.264): Defines the AVC video coding standard that MFC stereo coding builds upon.

• Other MPEG Conformance Testing Standards: Together they create a comprehensive ecosystem ensuring consistent implementation of audio-visual encoding technologies globally.

---

By adhering to ISO/IEC 14496-4:2004/Amd 42:2014, industry players can guarantee high fidelity, interoperable, and scalable stereo audio-visual coding solutions essential for modern multimedia consumption. This standard reinforces best practices for conformance testing in advanced stereo audio-visual coding extensions, ensuring seamless integration across digital platforms.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 14496-4 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
This Amendment establishes conformance test requirements for conformance to ITU-T Rec. H.264 |
ISO/IEC 14496-10.
In this Amendment, additional text to ITU-T Rec. H.264 | ISO/IEC 14496-4 is specified for testing the
conformance of ITU-T Rec. H.264.1 | ISO/IEC 14496-10 video decoders including in particular the MFC
High Profiles.
The following subclauses specify the normative tests for verifying conformance of ITU-T Rec. H.264 |
ISO/IEC 14496-10 video bitstreams and decoders. These normative tests make use of test data (bitstream
test suites) provided as an electronic annex to this document, and of the reference software decoder
specified in ITU-T Rec. H.264.2 | ISO/IEC 14496-5 with source code available in electronic format.

In 10.6.5.7, add the following text at the end of the subclause:
A decoder that conforms to the MFC High profile at a specific level shall be capable of decoding all
bitstreams in which all active MVC sequence parameter sets have any of the following:

— profile_idc is equal to 118 and constraint_set5_flag is equal to 1
— profile_idc equal to 100 or 77
— profile_idc equal to 88 and constraint_set1_flag equal to 1
— profile_idc equal to 66 and constraint_set1_flag equal to 1
and in which level_idc or the combination of level_idc and constraint_set3_flag for all active MVC
sequence parameter sets represent a level less than or equal to the specific level. In addition to the
bitstreams defined in Table AMD42.1, a decoder that conforms to the MFC High profile shall be capable
