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.
Amendement 1 to ISO/IEC 13818-1 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 Rec. H.222.0 (2006)/Amd.1 (01/2007).

ITU-T RECOMMENDATION
Information technology – Generic coding of moving pictures
and associated audio information: Systems
Amendment 1

Transport of MPEG-4 streaming text and MPEG-4 lossless audio over MPEG-2 systems
1) Subclause 1.2.3
Add the following references to subclause 1.2.3:
– ISO/IEC 14496-3:2005/Amd.1:2007, Low delay AAC profile.
– ISO/IEC 14496-17:2006, Information technology – Coding of audio-visual objects – Part 17: Streaming
text format.
2) Subclause 2.1.1
Replace, in the definition for access unit in subclause 2.1.1:
In the case of audio, an access unit is the coded representation of an audio frame.
by:
In the case of audio, an access unit is the coded representation of an audio frame, whereby each audio frame carries data
from one or more audio channels; an audio frame may carry for example one mono channel, or two stereo channels or
seven surround sound channels.
In the case of an ISO/IEC 14496-17 text stream, see ISO/IEC 14496-17 for the definition of an access unit.
3) New subclause 2.4.2.9
Add, after subclause 2.4.2.8:
2.4.2.9 T-STD extensions for carriage of ISO/IEC 14496-17 text streams
To define the decoding in the T-STD of ISO/IEC 14496-17 text streams carried in a Transport Stream, the
T-STD model needs to be extended. The T-STD extension and T-STD parameters for decoding of ISO/IEC 14496-17
text streams are defined in 2.15.3.1.
4) Subclause 2.4.3.5
Replace, in the semantics of "discontinuity indicator" under subclause 2.4.3.5 starting from the 5th paragraph:
For the purpose of this clause, an elementary stream access point is defined as follows:
• ISO/IEC 11172-2 video and ITU-T Rec. H.262 | ISO/IEC 13818-2 video – The first byte of a video
sequence header.
• ISO/IEC 14496-2 visual – The first byte of the visual object sequence header.
• ITU-T Rec. H.264 | ISO/IEC 14496-10 video – The first byte of an AVC access unit. The SPS and PPS
parameter sets referenced in this and all subsequent AVC access units in the coded video stream shall be
provided after this access point in the byte stream and prior to their activation.
• Audio – The first byte of an audio frame.

Typically, the transport syntax is used for providing sync words. The use of a specific transport syntax, if at all, is
specified in the clauses in this Specification specifying the transport of the various audio signals.
7) Subclause 2.5.2.4
Replace, in subclause 2.5.2.4 "PES streams":
Buffer sizes BS in the PES-STD model are defined as follows:
n
– For ITU-T Rec. H.262 | ISO/IEC 13818-2 video:
  BS = VBV [profile, level] + BS
n max oh
BS (1/750) seconds × R [profile, level], where VBV [profile, level] and R [profile, level] are
oh = max max max
the maximum VBV size and bit rate per profile, level, and layer as defined in Tables 8-13 and 8-14,
respectively, of ITU-T Rec. H.262 | ISO/IEC 13818-2. BS is allocated for PES packet header overhead.
oh
– For ISO/IEC 11172-2 video:
  BS = VBV + BS
n max oh
BS (1/750) seconds × R , where R and vbv_max refer to the maximum bitrate and maximum
oh = max max
vbv_buffer_size for a constrained parameter bitstream in ISO/IEC 11172-2 respectively.
– For ISO/IEC 11172-3 or ISO/IEC 13818-3 audio:
  BS = 2848 bytes
n
– For ITU-T Rec. H.264 | ISO/IEC 14496-10 video:
  BS = 1200 × MaxCPB[level] + BS
n oh
where MaxCPB[level] is defined in Table A.1 (Level Limits) in ITU-T Rec. H.264 | ISO/IEC 14496-10
for each level.
by:
As a PES stream only carries a single elementary stream, the buffer sizes in the PES-STD do not account for
multiplexing with other elementary streams, but only for multiplexing of the elementary stream carried in the PES
stream with PES headers, pack headers and system headers. The buffer sizes BS in the PES-STD model are defined as
n
follows:
– For ITU-T Rec. H.262 | ISO/IEC 13818-2 video:
  BS = VBV [profile, level] + BS
n max oh
BS = (1/750) seconds × R [profile, level], where VBV [profile, level] and R [profile, level] are
oh max max max
the maximum VBV size and bit rate per profile, level, and layer as defined in Tables 8-13 and 8-14,
respectively, of ITU-T Rec. H.262 | ISO/IEC 13818-2. BS is allocated for PES packet header overhead.
oh
– For ISO/IEC 11172-2 video:
  BS = VBV + BS
n max oh
BS = (1/750) seconds × R , where R and vbv_max refer to the maximum bitrate and maximum
oh max max
vbv_buffer_size for a constrained parameter bitstream in ISO/IEC 11172-2 respectively.
– For ISO/IEC 11172-3 or ISO/IEC 13818-3 audio:

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.
Amendement 1 to ISO/IEC 13818-1 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 Rec. H.222.0 (2006)/Amd.1 (01/2007).

text format.
2) Subclause 2.1.1
Replace, in the definition for access unit in subclause 2.1.1:
In the case of audio, an access unit is the coded representation of an audio frame.
by:
In the case of audio, an access unit is the coded representation of an audio frame, whereby each audio frame carries data
from one or more audio channels; an audio frame may carry for example one mono channel, or two stereo channels or
seven surround sound channels.
In the case of an ISO/IEC 14496-17 text stream, see ISO/IEC 14496-17 for the definition of an access unit.
3) New subclause 2.4.2.9
Add, after subclause 2.4.2.8:
2.4.2.9 T-STD extensions for carriage of ISO/IEC 14496-17 text streams
To define the decoding in the T-STD of ISO/IEC 14496-17 text streams carried in a Transport Stream, the
T-STD model needs to be extended. The T-STD extension and T-STD parameters for decoding of ISO/IEC 14496-17
text streams are defined in 2.15.3.1.
4) Subclause 2.4.3.5
Replace, in the semantics of "discontinuity indicator" under subclause 2.4.3.5 starting from the 5th paragraph:
For the purpose of this clause, an elementary stream access point is defined as follows:
• ISO/IEC 11172-2 video and ITU-T Rec. H.262 | ISO/IEC 13818-2 video – The first byte of a video
sequence header.
• ISO/IEC 14496-2 visual – The first byte of the visual object sequence header.
• ITU-T Rec. H.264 | ISO/IEC 14496-10 video – The first byte of an AVC access unit. The SPS and PPS
parameter sets referenced in this and all subsequent AVC access units in the coded video stream shall be
provided after this access point in the byte stream and prior to their activation.

  BS = VBV [profile, level] + BS
n max oh
BS (1/750) seconds × R [profile, level], where VBV [profile, level] and R [profile, level] are
oh = max max max
the maximum VBV size and bit rate per profile, level, and layer as defined in Tables 8-13 and 8-14,
respectively, of ITU-T Rec. H.262 | ISO/IEC 13818-2. BS is allocated for PES packet header overhead.
oh
– For ISO/IEC 11172-2 video:
  BS = VBV + BS
n max oh
BS (1/750) seconds × R , where R and vbv_max refer to the maximum bitrate and maximum
oh = max max
vbv_buffer_size for a constrained parameter bitstream in ISO/IEC 11172-2 respectively.
– For ISO/IEC 11172-3 or ISO/IEC 13818-3 audio:

n
– For ITU-T Rec. H.264 | ISO/IEC 14496-10 video:
  BS = 1200 × MaxCPB[level] + BS
n oh
where MaxCPB[level] is defined in Table A.1 (Level Limits) in ITU-T Rec. H.264 | ISO/IEC 14496-10
for each level.
by:
As a PES stream only carries a single elementary stream, the buffer sizes in the PES-STD do not account for
multiplexing with other elementary streams, but only for multiplexing of the elementary stream carried in the PES
stream with PES headers, pack headers and system headers. The buffer sizes BS in the PES-STD model are defined as
n
follows:
– For ITU-T Rec. H.262 | ISO/IEC 13818-2 video:
  BS = VBV [profile, level] + BS
n max oh
BS = (1/750) seconds × R [profile, level], where VBV [profile, level] and R [profile, level] are
oh max max max
the maximum VBV size and bit rate per profile, level, and layer as defined in Tables 8-13 and 8-14,
respectively, of ITU-T Rec. H.262 | ISO/IEC 13818-2. BS is allocated for PES packet header overhead.
oh
– For ISO/IEC 11172-2 video:
  BS = VBV + BS
n max oh
BS = (1/750) seconds × R , where R and vbv_max refer to the maximum bitrate and maximum
