Foreword
This European Standard (Telecommunications series) has been produced under the authority of the Joint Technical
Committee (JTC) of the European Broadcasting Union (EBU), Comité Européen de Normalisation ELECtrotechnique
(CENELEC) and the European Telecommunications Standards Institute (ETSI).
NOTE: The EBU/ETSI JTC was established in 1990 to co-ordinate the drafting of standards in the specific field
of broadcasting and related fields. Since 1995 the JTC 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 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 *.

Digital Video Broadcasting (DVB) Project
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 [1] 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 (i.e. EN 300 468) are specified in ETR 211 [7].

service: A sequence of programmes under the control of a broadcaster which can be broadcast as part of a schedule.
service_id: A unique identifier of a service within a TS.
Service Information (SI): Digital data describing the delivery system, content and scheduling/timing of broadcast data

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.
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: A table is comprised of a number of sub_tables with the same value of table_id.
Transport Stream (TS): A TS is a data structure defined in ISO/IEC 13818-1 [1]. It is the basis of the DVB standards.
transport_stream_id: A unique identifier of a TS within an original network.
The relationships of some of these definitions are illustrated in the service delivery model in figure 1.

4 Service Information (SI) description
ISO/IEC 13818 [1] specifies SI which is referred to as PSI. The PSI data provides information to enable automatic
configuration of the receiver to demultiplex and decode the various streams of programs within the multiplex.
The PSI data is structured as four types of table. The tables are transmitted in sections.
1) Program Association Table (PAT):
- for each service in the multiplex, the PAT indicates the location (the Packet Identifier (PID) values of the
Transport Stream (TS) packets) of the corresponding Program Map Table (PMT). It also gives the location of
the Network Information Table (NIT).
2) Conditional Access Table (CAT):
- the CAT provides information on the CA systems used in the multiplex; the information is private (not
defined within the present document) and dependent on the CA system, but includes the location of the EMM
stream, when applicable.
3) Program Map Table (PMT):
- the PMT identifies and indicates the locations of the streams that make up each service, and the location of
the Program Clock Reference fields for a service.
4) Network Information Table (NIT):
- the location of the NIT is defined in the present document in compliance with ISO/IEC 13818-1 [1]
specification, but the data format is outside the scope of ISO/IEC 13818-1 [1]. It is intended to provide
information about the physical network. The syntax and semantics of the NIT are defined in the present
document.
In addition to the PSI, data is needed to provide identification of services and events for the user. The coding of this data
is defined in the present document. In contrast with the PAT, CAT, and PMT of the PSI, which give information only
for the multiplex in which they are contained (the actual multiplex), the additional information defined within the present
document can also provide information on services and events carried by different multiplexes, and even on other
networks. This data is structured as nine tables:
1) Bouquet Association Table (BAT):
- the BAT provides information regarding bouquets. As well as giving the name of the bouquet, it provides a
list of services for each bouquet.
2) Service Description Table (SDT):
- the SDT contains data describing the services in the system e.g. names of services, the service provider, etc.
3) Event Information Table (EIT):
- the EIT contains data concerning events or programmes such as event name, start time, duration, etc.;
- the use of different descriptors allows the transmission of different kinds of event information e.g. for
different service types.
4) Running Status Table (RST):
- the RST gives the status of an event (running/not running). The RST updates this information and allows
timely automatic switching to events.
5) Time and Date Table (TDT):
- the TDT gives information relating to the present time and date. This information is given in a separate table
