Overview
ISO/IEC 14496-4:2004/Amd 31:2009 is an amendment to Part 4 of ISO/IEC 14496 (Coding of audio‑visual objects) that focuses on conformance testing for SVC profiles. Published by ISO/IEC in 2009, this document extends the Part 4 conformance framework to address the specific requirements and test materials needed for Scalable Video Coding (SVC) profiles. The amendment is supplied with electronic attachments (test resources and reference material) to support practical conformance testing and interoperability verification.
Key Topics
This amendment addresses the practical and technical aspects required to evaluate SVC profile implementations. Key topics covered include:
- Scope and purpose of conformance testing for SVC profiles within the ISO/IEC 14496-4 conformance framework.
- Conformance test materials and attachments, provided electronically to enable repeatable testing (reference bitstreams, metadata, and auxiliary files).
- Test procedures and execution guidance for verifying decoder/encoder behavior against SVC profile requirements.
- Criteria for pass/fail and reporting, defining how implementations demonstrate compliance and interoperability.
- Interoperability and consistency checks between implementations to aid developers and test laboratories.
Note: the amendment package is distributed with PDF and electronic files; installation/readme guidance ensures linked files and attachments function correctly in local environments.
Applications
This amendment is intended for organizations and professionals who need to validate that an SVC-capable implementation conforms to the ISO/IEC 14496 Part 4 requirements. Typical users include:
- Codec developers and firmware engineers implementing SVC profiles.
- Conformance and interoperability test laboratories performing formal compliance testing.
- Device manufacturers and OEMs integrating SVC-capable decoders/encoders into products (set‑top boxes, streaming devices, mobile devices).
- Quality assurance teams verifying that products meet standardized behavior across profiles and profiles combinations.
- Standards committees and integrators maintaining consistent test baselines for SVC implementations.
