Information technology — Coded representation of immersive media — Part 16: Reference software for versatile video coding

This document establishes a reference software for Rec. ITU-T H.266 | ISO/IEC 23090-3. NOTE The use of this reference software is not required for making an implementation of an encoder or decoder in conformance to Rec. ITU-T H.266 | ISO/IEC 23090-3. Requirements established in Rec. ITU-T H.266 | ISO/IEC 23090-3 take precedence over the behaviour of the reference software.

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.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria
needed for the different types of document should be noted. This document was drafted in
accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or

Introduction
This document provides reference software for Rec. ITU-T H.266 | ISO/IEC 23090-3. The reference
software includes both encoder and decoder functionality.
Reference software is useful in aiding users of a video coding standard to establish and test conformance
and interoperability, and to educate users and demonstrate the capabilities of the standard. For these
purposes, the accompanying software is provided as an aid for the study and implementation of Rec.
ITU-T H.266 | ISO/IEC 23090-3 Versatile video coding.
The software has been jointly developed by the ITU-T Visual Coding Experts Group (VCEG, Question
6 of ITU-T Study Group 16) and the ISO/IEC Moving Picture Experts Group (MPEG Joint Video Coding
Team with ITU-T SG 16, Working Group 5 of Subcommittee 29 of ISO/IEC Joint Technical Committee 1).
0.1  Purpose
The purpose of this document is to provide the following:
— Reference decoder software capable of decoding bitstreams that conform to Rec. ITU-T H.266 |
ISO/IEC 23090-3 in a manner that conforms to the decoding process specified in Rec. ITU-T H.266 |
ISO/IEC 23090-3.
— Reference encoder software capable of producing bitstreams that conform to Rec. ITU-T H.266 |
ISO/IEC 23090-3.
0.2  Examples of use
Some examples of uses that can be appropriate for the reference decoder software are as follows:
— As an illustration of how to perform the decoding process specified in Rec. ITU
