Overview
ISO/IEC 14496-2:2004/Amd 5:2009 is an important amendment to the international standard ISO/IEC 14496-2, part of the MPEG-4 series focused on the coding of audio-visual objects - specifically Part 2: Visual. Published by ISO and IEC Joint Technical Committee ISO/IEC JTC 1, this amendment introduces enhancements to the Simple Studio Profile by defining new Levels 5 and 6. These levels extend the standard to support higher visual session resolutions and increased bit rate capabilities, targeting professional video production and high-resolution studio environments.
The amendment, released in June 2009, specifies increased capabilities for video motion vector (VMV) size, video coding buffer (VCV) size and decoder rate, video buffering verifier (VBV) buffer size, and bit rate. These enhancements enable support for ultra-high-definition video formats at frame rates that are typical in modern studio productions.
Key Topics
- Simple Studio Profile Enhancement: Defines two new profile levels, Level 5 and Level 6, to accommodate more demanding studio video coding needs.
- Support for 4K Resolutions:
- Level 5 supports 4K x 2K resolution at 24p and 30p frame rates.
- Level 6 supports 4K x 2K resolution at 60p frame rate.
- Higher Bit Rate and Buffer Capacities: Increases maximum allowable video bit rates, buffer sizes, and decoder performance parameters compared to earlier profile levels, enabling efficient handling of large, high-fidelity video data.
- Coding Syntax Corrections: Updates to code syntax and variable length code definitions are included for accurate and consistent implementation.
- Macroblock Number Length Extension: Macroblock identification code length is extended from 14 to 16 bits for improved addressing in very large frame sizes.
- New Start Codes for Levels: Introduces new coded identifiers in the standard to represent Levels 5 and 6 within the Simple Studio Profile.
Applications
This amendment significantly benefits industries and sectors where ultra-high-definition video quality and frame rates are critical, including:
- Professional Video Production: Enables studios producing 4K content at cinematic frame rates to encode and distribute high-quality compressed video streams within the MPEG-4 framework.
- Broadcasting and Post-Production: Supports workflows requiring high-resolution visual coding with smooth frame rates for editing, special effects, and archiving.
- Digital Cinema: Aligns with requirements for digital film distribution, preservation, and playback at standard cinema resolutions and frame rates.
- Media Streaming Services: Assists streaming platforms aiming to deliver high-quality 4K content efficiently while adhering to international standards.
- Video Surveillance and Scientific Imaging: Applicable to systems needing large frame sizes combined with high frame rates and robust compression methods.
The amendment also encourages interoperability among hardware and software devices by providing standardized definitions for encoding, decoding, and buffer management of advanced studio-quality video.
Related Standards
- ISO/IEC 14496-2:2004 (Base Standard): The original edition of MPEG-4 Part 2, defining the core visual coding tools and profiles.
- ISO/IEC 14496 (MPEG-4): The full suite of standards specifying multimedia coding of audio-visual objects across multiple parts.
- ISO/IEC JTC 1/SC 29: The specific subcommittee responsible for developing standards in multimedia coding, including associated amendments and technical reports.
- MPEG Video Standards: Other video coding standards related to MPEG-2, MPEG-4 Part 10 (H.264/AVC), and HEVC relevant to comparison and complementing visual coding technologies.
- ITU-T Recommendations: Such as H.262 and H.263, which focus on video coding and compression techniques alongside MPEG standards.
By adopting ISO/IEC 14496-2:2004/Amd 5:2009, organizations and developers ensure compliance with the latest studio-level enhancements in visual object coding, facilitating future-proof video production and distribution workflows in line with global best practices.

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

Amendment 5 to ISO/IEC 14496-2:2004 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 specifies two new Levels for the ISO/IEC 14496-2 Simple Studio Profile: Levels 5 and 6.
These levels define increased capabilities of VMV size, VCV buffer size, VCV decoder rate, VBV buffer size,
and bit rate for the Simple Studio Profile. In particular, Level 5 provides support for typical visual session sizes
of 4Kx2K@24p/30p in rectangular-VOP luminance sample units. Level 6 provides support for typical visual
session sizes of 4Kx2K@60p in rectangular-VOP luminance sample units.
