Foreword
This European Standard (Telecommunications series) has been produced by Joint Technical Committee (JTC)
Broadcast of the European Broadcasting Union (EBU), Comité Européen de Normalisation ELECtrotechnique
(CENELEC) and the European Telecommunications Standards Institute (ETSI).
NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the
specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body
by including in the Memorandum of Understanding also CENELEC, which is responsible for the
standardization of radio and television receivers. The EBU is a professional association of broadcasting
organizations whose work includes the co-ordination of its members' activities in the technical, legal,
programme-making and programme-exchange domains. The EBU has active members in about
60 countries in the European broadcasting area; its headquarters is in Geneva.

Founded in September 1993, the DVB Project is a market-led consortium of public and private sector organizations in
the television industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television
services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters
market-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the
broadcast industry.

1 Scope
The present document specifies the Service Information (SI) data which forms a part of DVB bitstreams, in order that
the user can be provided with information to assist in selection of services and/or events within the bitstream, and so
that the Integrated Receiver Decoder (IRD) can automatically configure itself for the selected service. SI data for
automatic configuration is mostly specified within ISO/IEC 13818-1 [18] as Program Specific Information (PSI).
The present document specifies additional data which complements the PSI by providing data to aid automatic tuning of
IRDs, and additional information intended for display to the user. The manner of presentation of the information is not
specified in the present document, and IRD manufacturers have freedom to choose appropriate presentation methods.
It is expected that Electronic Programme Guides (EPGs) will be a feature of Digital TV transmissions.
The definition of an EPG is outside the scope of the present document (i.e. the SI specification), but the data contained
within the SI specified in the present document may be used as the basis for an EPG.
Rules of operation for the implementation of the present document are specified in TR 101 211 [i.2].

show
repeater: equipment which receives and re-transmits a DVB-T signal
NOTE: It can not change the TPS bits and thus the cell_id.
reserved: when used in the clause defining the coded bit stream, indicates that the value may be used in the future for
ISO defined extensions
NOTE: Unless otherwise specified within the present document all "reserved" bits is set to "1".
reserved_future_use: when used in the clause defining the coded bit stream, indicates that the value may be used in the

Service Information (SI): digital data describing the delivery system, content and scheduling/timing of broadcast data
streams, etc.
NOTE: It includes MPEG-2 PSI together with independently defined extensions.
ETSI
12 ETSI EN 300 468 V1.11.1 (2010-04)
subcell: geographical area that is part of the cells coverage area and that is covered with DVB-T signals by means of a
transposer
NOTE: In conjunction with the cell_id the cell_id_extension is used to uniquely identify a subcell.
sub_table: collection of sections with the same value of table_id and:
for a NIT: the same table_id_extension (network_id) and version_number;
for a BAT: the same table_id_extension (bouquet_id) and version_number;
for a SDT: the same table_id_extension (transport_stream_id), the same original_network_id and
version_number;
for a EIT: the same table_id_extension (service_id), the same transport_stream_id, the same original_network_id
and version_number.
NOTE: The table_id_extension field is equivalent to the fourth and fifth byte of a section when the
section_syntax_indicator is set to a value of "1".
table: comprised of a number of sub_tables with the same value of table_id
transmitter: equipment, that allows to modulate a baseband transport stream and to broadcast it on one frequency
Transport Stream (TS): data structure defined in ISO/IEC 13818-1 [18]
NOTE: It is the basis of the DVB standards.
transport_stream_id: unique identifier of a TS within an original network
transposer: type of repeater which receives a DVB-T signal and re-transmits it on a different frequency
The relationships of some of these definitions are illustrated in the service delivery model in figure 1.

Foreword
This European Standard (Telecommunications series) has been produced by Joint Technical Committee (JTC)
Broadcast of the European Broadcasting Union (EBU), Comité Européen de Normalisation ELECtrotechnique
(CENELEC) and the European Telecommunications Standards Institute (ETSI).
NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the
specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body
by including in the Memorandum of Understanding also CENELEC, which is responsible for the
standardization of radio and television receivers. The EBU is a professional association of broadcasting
organizations whose work includes the co-ordination of its members' activities in the technical, legal,
programme-making and programme-exchange domains. The EBU has active members in about
60 countries in the European broadcasting area; its headquarters is in Geneva.

Founded in September 1993, the DVB Project is a market-led consortium of public and private sector organizations in
the television industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television
services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters
market-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the
broadcast industry.

1 Scope
The present document specifies the Service Information (SI) data which forms a part of DVB bitstreams, in order that
the user can be provided with information to assist in selection of services and/or events within the bitstream, and so
that the Integrated Receiver Decoder (IRD) can automatically configure itself for the selected service. SI data for
automatic configuration is mostly specified within ISO/IEC 13818-1 [18] as Program Specific Information (PSI).
The present document specifies additional data which complements the PSI by providing data to aid automatic tuning of
IRDs, and additional information intended for display to the user. The manner of presentation of the information is not
specified in the present document, and IRD manufacturers have freedom to choose appropriate presentation methods.
It is expected that Electronic Programme Guides (EPGs) will be a feature of Digital TV transmissions.
The definition of an EPG is outside the scope of the present document (i.e. the SI specification), but the data contained
within the SI specified in the present document may be used as the basis for an EPG.
Rules of operation for the implementation of the present document are specified in TR 101 211 [i.2].

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
AC-3: refers to the coding of audio using the Dolby AC-3 method
NOTE: The Service Information requirements for AC-3 streams carried in DVB systems are described in
annex D. The carriage of AC-3 elementary streams as private data within MPEG systems is described in
annex C of TS 101 154 [9].
bouquet: collection of services marketed as a single entity
broadcaster (SERVICE Provider): organization which assembles a sequence of events or programmes to be delivered
to the viewer based upon a schedule
cell: geographical area that is covered with DVB-T signals delivering one or more particular transport streams
throughout the area by means of one or more transmitters
NOTE: The cell may in addition contain repeaters. Two neighbouring cells may be intersecting or fully
overlapping. The cell_id that is used to uniquely identify a cell is unique within each original_network_id.
For hand-over purposes it is more convenient if the transport streams associated with the cell cover
exactly the same area, or only one transport stream per cell is used.
component (ELEMENTARY Stream): one or more entities which together make up an event
EXAMPLE: Video, audio, teletext.
Conditional Access (CA) system: system to control subscriber access to services, programmes and events
EXAMPLE: Videoguard, Eurocrypt.
ETSI
11 ETSI EN 300 468 V1.11.1 (2010-04)
delivery system: physical medium by which one or more multiplexes are transmitted
EXAMPLE: Satellite system, wide-band coaxial cable, fibre optics, terrestrial channel of one emitting point.
Entitlement Management Messages (EMM): private Conditional Access information which specify the authorization
levels or the services of specific decoders
NOTE: They may be addressed to individual decoder or groups of decoders.
event: grouping of elementary broadcast data streams with a defined start and end time belonging to a common service
EXAMPLE: First half of a football match, News Flash, first part of an entertainment show.
forbidden: when used in the clauses defining the coded bit stream, indicates that the value shall never be used
MPEG-2: See ISO/IEC 13818.
NOTE: Systems coding is defined in part 1 [18]. Video coding is defined in part 2 [19]. Audio coding is defined
in part 3 [20].
multiplex: stream of all the digital data carrying one or more services within a single physical channel
network: collection of MPEG-2 Transport Stream (TS) multiplexes transmitted on a single delivery system
EXAMPLE: All digital channels on a specific cable system.
n PSK: n-valued Phase Shift Keying (other than quaternary)
original_network_id: unique identifier of a network
programme: concatenation of one or more events under the control of a broadcaster e.g. news show, entertainment
show
