Overview
ISO/IEC 14496-4:2004/Amd 35:2009 is an amendment to the international standard for Information Technology - Coding of Audio-Visual Objects - Part 4: Conformance Testing. This amendment specifically addresses the introduction of conformance testing procedures for Simple Studio Profile Levels 5 and 6. Developed by ISO/IEC Joint Technical Committee JTC 1, Subcommittee SC 29, this update ensures robust testing methodologies for higher complexity video encoding profiles, enhancing decoder reliability and interoperability.
The amendment includes detailed specifications for test bitstreams used to validate decoder compliance with the maximum allowed bitrate, macroblock rates, packet sizes, and Video Buffering Verifier (VBV) parameters for these levels. By defining precise conformance criteria, it supports manufacturers and developers in maintaining standard-compliant decoding performance for advanced audio-visual coding profiles.
Key Topics
Simple Studio Profile Levels 5 and 6: The amendment expands conformance testing coverage to include Levels 5 and 6, which represent advanced configurations in the Simple Studio Profile family.
Conformance Testing Framework: Introduction of new test bitstreams designed to exercise decoder buffering and I/O bandwidth limits, ensuring devices handle the maximum bitrates and frame complexities allowed for these profile levels.
Test Bitstream Specifications:
- Bitstreams utilize frame_pred_frame_dct equal to 1.
- Test parameters stress the decoder with macroblocks per second, packet sizes, and bitrates at the maximum permitted.
- VBV fullness fluctuates between maximum and minimum levels to simulate real-world buffering conditions, verifying decoder efficiency.
Functional Stage Covered: Primarily focuses on the VBV (Video Buffering Verifier) accounting for decoder buffer management and latency performance.
Test Bitstream Deliverables: Coordinated release of bitstream files donated by industry contributors, such as Sony and NHK, available for comprehensive conformance verification.
Applications
This amendment serves practical purposes across multiple domains in digital video technology:
Decoder Development & Validation: Manufacturer decoding devices, including software and hardware players, can utilize these rigorous conformance tests to certify support for Simple Studio Profile Levels 5 and 6.
Quality Assurance: Quality control teams apply the specified bitstreams to perform stress tests, ensuring that playback devices handle peak encoding parameters without degradation or buffering issues.
Broadcast and Streaming: Professionals involved in TV, online video platforms, and multimedia distribution rely on standardized conformance to guarantee consistent multimedia delivery that meets international quality standards.
Video Codec Research: Codec developers and researchers leverage the amendment’s test procedures to benchmark new encoding/decoding algorithms against established profile requirements.
Related Standards
ISO/IEC 14496-4:2004/Amd 35:2009 complements several key standards in the multimedia coding ecosystem:
ISO/IEC 14496-2 (MPEG-4 Part 2): Defines the core video coding technology and profiles, including the Simple Studio Profile levels the amendment targets.
ISO/IEC 14496-1: Systems standard that provides the framework for multimedia object representation and interleaving.
Other Conformance Testing Parts of ISO/IEC 14496: Earlier amendments and parts of the conformance testing suite ensure comprehensive coverage across various profiles and levels.
ISO/IEC JTC 1/SC 29 Standards: Additional standards developed by the same committee cover audio coding, MPEG video series, and container formats, providing a holistic multimedia coding infrastructure.

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.
