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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
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 Amendment may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to International Standard ISO/IEC 13818-6:1998 was prepared by Joint Technical Committee
ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia
information.

Information technology — Generic coding of moving pictures and
associated audio information — Part 6: Extensions for DSM-CC
AMENDMENT 1: Additions to support data broadcasting
1) Replace the semantic definition of DownloadInfoIndication moduleSize in subclause 7.3.2 with the following:
"
The moduleSize field is the length, in bytes, of the described module. A value of zero indicates that the module
size is not specified.
"
2) Replace the last paragraph in subclause 9.2.1 with the following:
"
MPEG-2 Systems, ISO/IEC 13818-1:2000, defines generic table section syntax that DSM-CC uses to provide re-
assembly of Transport Stream packets into DSM-CC messages. This specification defines additional semantics on
ISO/IEC 13818-1:2000 sections to support additional DSM-CC requirements. Called DSMCC_section and
DSMCC_Addressable_section, the syntax is compatible with the generic section syntax so that compliant MPEG-2
Systems decoders may be used.
"
3) In subclause 9.2.2, replace every occurrence of "private_section" with "generic_section"
4) In subclause 9.2.2, replace every occurrence of "private_indicator" with "complement_indicator".
5) Replace Table 9-3 with the following:
"
Table 9-3 DSM-CC table_id assignments
table_id DSMCC Section Type
0x00 - 0x37 ITU-T Rec. H.222.0 | ISO/IEC 13818-1 defined
0x38 - 0x39 ISO/IEC 13818-6 reserved
0x3A DSM-CC Sections containing multi-protocol encapsulated data
0x3B DSM-CC Sections containing U-N Messages, except Download Data Messages
0x3C DSM-CC Sections containing Download Data Messages
0x3D DSM-CC Sections containing Stream Descriptors
0x3E DSM-CC Sections containing private data
0x3F DSM-CC Addressable Sections
0x40 - 0xFE User private
0xFF forbidden
"
6) In subclause 9.2.2.1 replace the corresponding paragraphs with the following:
"
version_number -- This field is a 5-bit field. If the value of the table_id field equals 0x3A or 0x3B, this field shall be
set to zero. If the value of the table_id field equals 0x3C and a DownloadDataBlock Message is conveyed, this field
shall have the value of the least significant 5 bits of the moduleVersion field of the conveyed DownloadDataBlock
Message. If the value of the table_id field equals 0x3C and a DownloadDataRequest Message is conveyed, this

field shall be set to zero. If the value of table_id equals 0x3D, then this field shall be set as defined in ISO/IEC
13818-1:2000. If the value of the table_id field equals 0x3E, then the value and use of this field are defined by the
user.
current_next_indicator -- This is a 1 bit flag. If the value of the table_id field equals 0x3A, 0x3B or 0x3C, this bit
shall be set to ‘1’. Otherwise, this field shall be set as defined in ISO/IEC 13818-1:2000.
section_number -- This field is a 8-bit field. If the value of the table_id field equals 0x3A or 0x3B, this field shall be
set to zero. If the value of the table
