ISO/IEC 14496-4:2004/Amd 38:2010/Cor 1:2012

Overview

This Technical Corrigendum (Cor 1:2012) to ISO/IEC 14496-4:2004/Amd.38:2010 updates the conformance testing materials for Multiview Video Coding (MVC). Prepared by ISO/IEC JTC 1/SC 29, the corrigendum instructs implementers to replace existing bitstreams with the new files provided in the electronic attachments and to replace Table AMD38-1 with the revised table content.

The document focuses on ensuring up-to-date test vectors and reference bitstreams for MVC conformance and interoperability testing, and it lists donated bitstreams and contributors used as official test material.

Key Topics

• Replacement of bitstreams: All previously published MVC bitstreams associated with Amendment 38 are superseded by the new bitstreams available in the attachments.
• Updated reference table: Table AMD38-1 is replaced with an updated listing that categorizes bitstreams by test focus and provides donor and file-name mappings.
• Conformance scope: The corrigendum addresses conformance testing items specific to multiview implementations, including dependency structure, number of views, reference picture construction, interlaced coding tools, and subset SPS.
• Donor organizations and examples: The corrigendum explicitly lists donated bitstreams and donors, helping implementers locate canonical test vectors. Examples from the corrigendum include:
  • NTT: MVCDS-1, MVCDS-2, MVCDS-3, MVCNV-1, MVCNV-4
  • Mitsubishi: MVCDS-4, MVCDS-5, MVCDS-6, MVCNV-2, MVCNV-3, MVCSPS-1, MVCSPS-2
  • Qualcomm: MVCRP-1 through MVCRP-6
  • Panasonic: MVCICT-1, MVCICT-2
• Frame rates and levels: The corrigendum lists frame-rate and level indicators for test bitstreams, for example entries with 3 / 29.97 and 3.1 / 25 frame/sec values.

Applications

This corrigendum is practical for:

• Implementers and developers of MVC decoders and encoders seeking authoritative test vectors for conformance verification.
• Test labs and QA teams validating interoperability across multiview implementations using updated official bitstreams.
• Standards maintainers and integrators ensuring test suites reference the current canonical materials.

Benefits include clearer, centralized test resources, reduced ambiguity about which bitstreams are normative, and improved interoperability outcomes when vendors use the updated test set.

Related Standards

• ISO/IEC 14496-4 (Part 4: Conformance testing) - the parent specification covering conformance procedures for coding of audiovisual objects.
• Other ISO/IEC JTC 1/SC 29 outputs on video coding and multimedia may provide complementary context for implementing and testing MVC features.
