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
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 23008-5 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information, in collaboration with
ITU-T. The identical text is published as ITU-T H.265 (08/2014).

Introduction
This Recommendation | International Standard accompanies reference software for Rec. ITU-T H.265 |
ISO/IEC 23008-2 High efficiency video coding. 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.265 |
ISO/IEC 23008-2 High efficiency video coding.
The software has been jointly developed by the ITU-T Video Coding Experts Group (VCEG, Question 6 of
ITU-T Study Group 16) and the ISO/IEC Moving Picture Experts Group (MPEG, Working Group 11 of
Subcommittee 29 of ISO/IEC Joint Technical Committee 1).
0.1 Purpose
The purpose of this Recommendation | International Standard is to provide the following:
– Reference decoder software capable of decoding bitstreams that conform to Rec. ITU-T H.265 | ISO/IEC
23008-2 in a manner that conforms to the decoding process specified in Rec. ITU-T H.265 | ISO/IEC
23008-2.
– Reference encoder software capable of producing bitstreams that conform to
Rec. ITU-T H.265 | ISO/IEC 23008-2.
0.2 Examples of use
Some examples of uses that may be appropriate for the reference decoder software are as follows:
– As an illustration of how to perform the decoding process specified in Rec. ITU-T H.265 |
ISO/IEC 23008-2.
– As the starting basis for the implementation of a decoder that conforms to Rec. ITU-T H.265 |
ISO/IEC 23008-2.
– For testing the conformance of a decoder implementation with the decoding process specified in
Rec. ITU-T H.265 | ISO/IEC 23008-2 (as the values of the samples in all decoded pictures and the
relative ordering of those pictures will be identical from all conforming decoder implementations that
support the profile and level used in a bitstream that conforms to Rec. ITU-T H.265 | ISO/IEC 23008-2).
– For testing the conformance of a bitstream to the constraints specified for bitstream conformance in Rec.
ITU-T H.265 | ISO/IEC 23008-2, as the software can detect and report many bitstream conformance
violations.
NOTE 1 – However, the lack of the detection of any conformance violation by the reference decoder software
should not be considered as definitive proof that the bitstream conforms to all constraints specified for bitstream
conformance in Rec. ITU-T H.265 | ISO/IEC 23008-2.
Some examples of uses that may be appropriate for the reference encoder software are as follows:
– As an illustration of how to perform an encoding process that produces bitstreams that conform to the
constraints specified for bitstream conformance in Rec. ITU-T H.265 | ISO/IEC 23008-2.
– As the starting basis for the implementation of an encoder that conforms to
Rec. ITU-T H.265 | ISO/IEC 23008-2.
– As a means of generating bitstreams for testing the conformance of a decoder implementation with the
decoding process specified in Rec. ITU-T H.265 | ISO/IEC 23008-2.
– As a means of evaluating and demonstrating examples of the quality that can be achieved by an encoding
process that conforms to Rec. ITU-T H.265 | ISO/IEC 23008-2.
NOTE 2 – However, no guarantee of the quality that will be achieved by an e
