RECOMMENDATION ITU-T

Technical Corrigendum 1
Correction of zero_byte syntax element and stream_id_extension mechanism

1) Subclause 2.14.1
Delete the following bullet point and Note:
• Each byte stream NAL Unit that carries the access unit delimiter shall contain exactly one zero_byte
syntax element.
NOTE 3 – The syntax and semantics of byte stream NAL units are defined in Annex B of ITU-T Rec. H.264 |
ISO/IEC 14496-10.
2) Subclause 2.4.3.6
Change Table 2-21 as indicated below, so as to ensure byte alignement in case the stream_id_extension_flag is '1':

   ---
  --- Unchanged initial part of Table 2-21 ---
   ---
  if ( PES_extension_flag_2 = = '1') {
  marker_bit 1 bslbf
  PES_extension_field_length 7 uimsbf
  stream_id_extension_flag 1 bslbf
  if (stream_id_extension_flag == '0') {
   stream_id_extension 7 uimsbf
   }
  else {
   reserved 7 bslbf
   }
  for (i = 1; i < PES_extension_field_length; i++) {
   reserved 8 bslbf
  }
  }
   ---
  --- Unchanged trailing part of Table 2-21 ---

3) Subclause 2.5.3.5
Replace Table 2-40 with the following:
Table 2-40 – Program Stream system header

 P-STD_buffer_bound_scale 1 bslbf
 P-STD_buffer_size_bound 13 uimsbf
 }
}
}
4) Subclause 2.5.3.6
Change the following paragraphs:
stream_id – The stream_id is an 8-bit field that indicates the coding and elementary stream number of the stream to
which the following P-STD_buffer_bound_scale and P-STD_buffer_size_bound fields refer.
If stream_id equals '1011 1000' the P-STD_buffer_bound_scale and P-STD_buffer_size_bound fields following the
stream_id refer to all audio streams in the Program Stream.
If stream_id equals '1011 1001' the P-STD_buffer_bound_scale and P-STD_buffer_size_bound fields following the
stream_id refer to all video streams in the Program Stream.
If stream_id equals '1111 1101', the P-STD_buffer_bound_scale and P-STD_buffer_size_bound fields following the
stream_id refer to all elementary streams with an extended_stream_id in the Program Stream, independent of the coded
value of the stream_id_extension in the PES header of those streams.
If stream_id equals '1011 0111', the following stream_id_extension field shall be interpreted as referring to the stream
coding and elementary stream number according to Table 2-27.
If the stream_id takes on any other value it shall be a byte value greater than or equal to '1011 1100' and shall be
interpreted as referring to the stream coding and elementary stream number according to Table 2-22.
Each elementary stream present in the Program Stream shall have its P-STD_buffer_bound_scale and
P-STD_buffer_size_bound specified exactly once by this mechanism in each system header.

ISO/IEC 13818-1:2007/Cor.1:2008 (E)
stream_id_extension – The stream_id_extension is a 7-bit field. In case the stream_id field is coded with the value
'1011 0111', then the stream_id_extension indicates the coding and elementary stream number of the stream with an
extended_stream_id to which the P-STD_buffer_bound_scale and P-STD_buffer_size_bound fields following the
stream_id_extension field refer.
5) Subclause 2.5.4.1
Replace Table 2-41 with the following:
