Foreword
This European Standard (EN) 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.

The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network
operators, software developers, regulatory bodies, content owners and others committed to designing global standards
for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and
economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital
television from transmission through interfacing, conditional access and interactivity for digital video, audio and data.
The consortium came together in 1993 to provide global standardisation, interoperability and future proof
specifications.

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 TS 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 data streams to be delivered
to the viewer; the delivery can be 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.
ETSI
12 ETSI EN 300 468 V1.13.1 (2012-08)
Conditional Access (CA) system: system to control subscriber access to services, data streams and events
EXAMPLE: Videoguard, Eurocrypt.
delivery system: physical medium by which one or more DVB transport streams are transmitted
EXAMPLE: Satellite system, wide-band coaxial cable, fibre optics, terrestrial channel of one emitting point.
DVB transport stream: an MPEG-2 transport stream [18] containing the mandatory DVB-SI signalling as defined in
the present document
NOTE: It is recommended that the DVB-SI implementation guidelines [i.2] should be followed in addition. They
define additional requirements for the signalling to help improve the quality of experience for viewers.
event: grouping of elementary broadcast data streams with a defined start time and duration 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 is never used
MPEG-2: See ISO/IEC 13818 [18].
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].
network: managed and navigable collection of DVB transport streams transmitted on one or more delivery systems
generally based on the same physical medium
NOTE 1: It is possible to operate both, first and second generation delivery systems in the same network (e.g.
DVB-T and DVB-T2).
NOTE 2: A network is identified by its network_id. It might be composed of one or more emitting sites.
n PSK: n-valued Phase Shift Keying (other than quaternary)
original_network_id: unique identifier of a broadcast platform operator

The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network operators, software developers, regulatory bodies, content owners and others committed to designing global standards for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications.

ETSI ETSI EN 300 468 V1.13.1 (2012-08) 8 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 TS 101 211 [i.2]. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies.

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 data streams to be delivered to the viewer; the delivery can be 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.
