11、-10:2005/FDAM 2:2007(E) iv ISO/IEC 2007 All rights reserved 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
12、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 n
13、on-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 mai
14、n 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 casti
15、ng 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
16、/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. ISO/IEC 14496-10:2005/FDAM 2:2007(E)
17、 ISO/IEC 2007 All rights reserved 1 Information technology Coding of audio-visual objects Part 10: Advanced Video Coding 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
18、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 th
19、e 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 “
20、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/IE
21、C 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
22、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
23、 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
24、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 rem
25、oved. 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
26、 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 In
27、tra, 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). -,-,- ISO/IEC 14496-10:2005/FDAM 2:2007(E) 2 ISO/IEC 2007 All rights reserved In the second paragraph of
28、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 decodi
29、ng 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 va
30、lues 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
31、-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-calle
32、d 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 o
33、f 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 p
34、icture 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
35、 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 ra
36、ster 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
37、group map, and, when a picture is coded using three separate colour planes, a colour plane identifier. -,-,- ISO/IEC 14496-10:2005/FDAM 2:2007(E) ISO/IEC 2007 All rights reserved 3 In subclause 6.2 “Source, decoded, and output picture formats”, make the following changes. Replace the following: The
38、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, a

42、4:4:4 - - Replace the following paragraph: In 4:4:4 sampling, each of the two chroma arrays has the same height and width as the luma array. with: In 4:4:4 sampling, depending on the value of separate_colour_plane_flag, the following applies. If separate_colour_plane_flag is equal to 0, each of the
43、two chroma arrays has the same height and width as the luma array. ISO/IEC 14496-10:2005/FDAM 2:2007(E) 4 ISO/IEC 2007 All rights reserved Otherwise (separate_colour_plane_flag is equal to 1), the three colour planes are separately processed as monochrome sampled pictures. Replace the following para
44、graph: 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 necessa
45、ry 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
46、 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 subdivisi
47、on 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 repre
