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.
Amendment 2 to ISO/IEC 14496-10:2005 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia
information.
Amendment 2 to ISO/IEC 14496-10:2005 is technically aligned with ITU-T Rec. H.264 (2005)/Amd.2 (2007),
but is not published as identical text.

AMENDMENT 2: New profiles for professional applications
In subclause 0.4, replace the following:
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 1 refers to the first (2003) approved version of this
Recommendation | International Standard.
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 2 refers to the integrated text containing the corrections specified in the
first technical corrigendum.
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 3 refers to the integrated text containing both the first technical
corrigendum (2004) and the first amendment, which is referred to as the "Fidelity range extensions".
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 4 (the current specification) refers to the integrated text containing the
first technical corrigendum (2004), the first amendment (the "Fidelity range extensions"), and an additional technical
corrigendum (2005). In the ITU-T, the next published version after version 2 was version 4 (due to the completion of the
drafting work for version 4 prior to the approval opportunity for a final version 3 text).
with:
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 1 refers to the first (2003) approved version of this
Recommendation | International Standard. The first published version in ISO/IEC corresponded to version 1.
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 2 refers to the integrated text containing the corrections specified in the
first technical corrigendum. The first fully-published version in the ITU-T was version 2, due to the development of the
corrigendum during the publication process. Version 2 was also published in integrated form by ISO/IEC.
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 3 refers to the integrated text containing both the first technical
corrigendum (2004) and the first amendment, which is referred to as the "Fidelity range extensions".
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 4 refers to the integrated text containing the first technical corrigendum
(2004), the first amendment (the "Fidelity range extensions"), and an additional technical corrigendum (2005). In both
ITU-T and ISO/IEC, the next complete published version after version 2 was version 4.
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 5 refers to the integrated version 4 text with its specification of the High
4:4:4 profile removed. In ISO/IEC, the changes from version 4 to version 5 were published as a corrigendum text.
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 6 refers to the integrated version 5 text after its amendment to support
additional colour space indicators. In the ITU-T, the changes for versions 5 and 6 were approved and published as a
single amendment.
ITU-T Rec. H.264 | ISO/IEC 14496-10 version 7 refers to the integrated version 6 text after its amendment to define five
new profiles intended primarily for professional applications (the High 10 Intra, High 4:2:2 Intra, High 4:4:4 Intra,
CAVLC 4:4:4 Intra, and High 4:4:4 Predictive profiles) and two new types of supplemental enhancement information
(SEI) messages (the post-filter hint SEI message and the tone mapping information SEI message).

In the second paragraph of subclause 0.6, replace the sentence:
With the exception of the transform bypass mode of operation for lossless coding in the I_PCM mode of operation in all
profiles, the algorithm is typically not lossless, as the exact source sample values are typically not preserved through the
encoding and decoding processes.
with:
With the exception of the transform bypass mode of operation for lossless coding in the High 4:4:4 Intra,
CAVLC 4:4:4 Intra, and High 4:4:4 Predictive profiles, and the I_PCM mode of operation in all profiles, the algorithm is
typically not lossless, as the exact source sample values are typically not preserved through the encoding and decoding
processes.

In the third paragraph of subclause 0.7, replace the sentence:
Annex A specifies six profiles (Baseline, Main, Extended, High, High 10 and High 4:2:2), each being tailored to certain
application domains, and defines the so-called levels of the profiles.
with:
Annex A specifies eleven profiles (Baseline, Main, Extended, High, High 10, High 4:2:2, High 4:4:4 Predictive,
High 10 Intra, High 4:2:2 Intra, High 4:4:4 Intra, and CAVLC 4:4:4 Intra), each being tailored to certain application
domains, and defines the so-called levels of the profiles.

Replace subclause 3.6 with the following:
3.6 arbitrary slice order: A decoding order of slices in which the macroblock address of the first macroblock of
some slice of a picture may be less than the macroblock address of the first macroblock of some other preceding
slice of the same coded picture or, in the case of a picture that is coded using three separate colour planes, some
other preceding slice of the same colour plane.

Replace subclause 3.75 with the following:
3.75 macroblock: A 16x16 block of luma samples and two corresponding blocks of chroma samples of a picture that
has three sample arrays; or a 16x16 block of samples of a monochrome picture or a picture that is coded using
three separate colour planes. The division of a slice or a macroblock pair into macroblocks is a partitioning.

Replace subclause 3.136 with the following:
3.136 slice: An integer number of macroblocks or macroblock pairs ordered consecutively in the raster scan within a
particular slice group. For the primary coded picture, the division of each slice group into slices is a
partitioning. Although a slice contains macroblocks or macroblock pairs that are consecutive in the raster scan
within a slice group, these macroblocks or macroblock pairs are not necessarily consecutive in the raster scan
within the picture. The addresses of the macroblocks are derived from the address of the first macroblock in a
slice (as represented in the slice header), the macroblock to slice group map, and, when a picture is coded using
three separate colour planes, a colour plane identifier.

In subclause 6.2 “Source, decoded, and output picture formats”, make the following changes.
Replace the following:
The variables SubWidthC, and SubHeightC are specified in Table 6-1, depending on the chroma format sampling
structure, which is specified through chroma_format_idc. An entry marked as "-" in Table 6-1 denotes an undefined
value for SubWidthC or SubHeightC. Other values of chroma_format_idc, SubWidthC, and SubHeightC may be
specified in the future by ITU-T | ISO/IEC.

---------------------- Page: 6 ----------------------
ISO/IEC 14496-10:2005/Amd.2:2007(E)
– Otherwise (separate_colour_plane_flag is equal to 1), the three colour planes are separately processed as
monochrome sampled pictures.

Replace the following paragraph:
The number of bits necessary for the representation of each of the samples in the luma and chroma arrays in a video
sequence is in the range of 8 to 12, and the number of bits used in the luma array may differ from the number of bits used
in the chroma arrays.
with:
The number of bits necessary for the representation of each of the samples in the luma and chroma arrays in a video
sequence is in the range of 8 to 14, and the number of bits used in the luma array may differ from the number of bits used
in the chroma arrays.
Replace the following paragraph:
– If chroma_format_idc is equal to 0 (monochrome), MbWidthC and MbHeightC are both equal to 0 (as no chroma
arrays are specified for monochrome video).
with:
– If chroma_format_idc is equal to 0 (monochrome) or separate_colour_plane_flag is equal to 1, MbWidthC and
MbHeightC are both set equal to 0.

In subclause 6.3 “Spatial subdivision of pictures and slices”, make the following changes:
Replace the following:
Each macroblock is comprised of one 16x16 luma array and, when the video format is not monochrome, two
corresponding chroma sample arrays. When macroblock-adaptive frame/field decoding is not in use, each macroblock
represents a spatial rectangular region of the picture. For example, a picture may be divided into two slices as shown in
Figure 6-7.
with:
Each macroblock is comprised of one 16x16 luma array and, when the chroma sampling format is not equal to 4:0:0 and
separate_colour_plane_flag is equal to 0, two corresponding chroma sample arrays. When separate_colour_plane_flag is
equal to 1, each macroblock is comprised of one 16x16 luma or chroma sample array. When macroblock-adaptive
frame/field decoding is not in use, each macroblock represents a spatial rectangular region of the picture. For example, a
picture may be divided into two slices as shown in Figure 6-7.
When a picture is coded using three separate colour planes (separate_colour_plane_flag is equal to 1), a slice contains
only macroblocks of one colour component being identified by the corresponding value of colour_plane_id, and each
colour component array of a picture consists of slices having the same colour_plane_id value. Coded slices with
different values of colour_plane_id within an access unit can be interleaved with each other under the constraint that for
each value of colour_plane_id, the coded slice NAL units with that value colour_plane_id shall be in the order of
increasing macroblock address for the first macroblock of each coded slice NAL unit.

In subclause 7.4.1.2.5 “Order of VCL NAL units and association to coded pictures”, replace the following paragraph:
- Otherwise (arbitrary slice order is not allowed), the order of coded slice of an IDR picture NAL units shall be in the
order of increasing macroblock address for the first macroblock of each coded slice of an IDR picture NAL unit.

with:
- Otherwise (arbitrary slice order is not allowed), the following applies.
– If separate_colour_plane_flag is equal to 0, the order of coded slices of IDR picture NAL units shall be in
the order of increasing macroblock address for the first macroblock of each coded slice of an IDR picture
NAL unit.

– Otherwise (separate_colour_plane_flag is equal to 1), the order of coded slices of IDR picture NAL units
for each value of colour_plane_id shall be in the order of increasing macroblock address for the first
macroblock of each coded slice of the particular value of colour_plane_id of an IDR picture NAL unit.
NOTE – When separate_colour_plane_flag is equal to 1, the relative ordering of coded slices having different values
of colour_plane_id is not constrained.

In subclause 7.4.2.1 “Sequence parameter set RBSP semantics”, make the following changes.
Replace the paragraphs that state as follows:
NOTE – When more than one of constraint_set0_flag, constraint_set1_flag, or constraint_set2_flag are equal to 1, the bitstream
obeys the constraints of all of the indicated subclauses of subclause A.2.
