SIST EN 300 468 V1.4.1:2005

Digital Video Broadcasting (DVB); Specification for Service Information (SI) in DVB systems

Extension to cover AC-3, mobile DVB-T and backwards compatible modifications in the light of implementations experiences.  To bring into line with ETR revision  Specification of Service Information (SI) data which forms part of DVB /MPEG-2 bitstreams, in order that the user can be provided with inform ation to assist in selection of services and/or events within the bits tream, and so that the Integrated Receiver Decoder (IRD) can automatically configure itself for the selected service. SI is specified in ISO/IEC 13818-1 as Programme Specific Information (PSI). This specification complements the PSI by providing data to aid automatic tuning of IRDs, and addditional information intended for display to the user, mainly in text form. The manner of presentation of the information is not specified, and IRD manufacturers have freedom to choose appropriate presentation methods. It is expected that Electronic Programme Guides (EPG) will be a feature of Digital TV transmissions. The definition of EPG is outside the scope of the SI specification, but the data contained within the SI specified here could be used as basis for an EPG. The present specification describes Service Information (SI) for use in broadcast MPEG-2 bitstreams. The MPEG-2 System layer specifies SI which is referred to as Programme Specific Information (PSI). The PSI data provides information to enable automatic configuration of the receiver to demultiplex and decode the various streams of programme within the multiplex.

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].

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 ITU-R Recommendation BS.1196 [19]. The Service
Information requirements for AC-3 streams carried in DVB systems is described in annex E of the present document.
The carriage of AC-3 elementary streams as private data within MPEG systems is described in annex C of
ETR 154 [12].
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: cell is a geographical area that is covered with DVB-T signals by means of one or more transmitters each radiating
a particular transport stream on only one frequency. The cell may in addition contain repeaters. Two neighbouring cells
may have an intersection. The cell_id that is used to uniquely identify a cell shall be unique within each
original_network_id.
component (ELEMENTARY Stream): one or more entities which together make up an event, e.g. video, audio,
teletext.

Conditional Access (CA) system: system to control subscriber access to services, programmes and events
e.g. Videoguard, Eurocrypt.
delivery system: physical medium by which one or more multiplexes are transmitted e.g. satellite system, wide-band
coaxial cable, fibre optics, terrestrial channel of one emitting point.
Entitlement Management Messages (EMM): are private Conditional Access information which specify the
authorization levels or the services of specific decoders. 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,
e.g. first half of a football match, News Flash, first part of an entertainment show.
forbidden: term "forbidden" when used in the clauses defining the coded bit stream, indicates that the value shall never
be used.
MPEG-2: refers to the standard ISO/IEC 13818-1 [1]. Systems coding is defined in part 1. Video coding is defined in
part 2. Audio coding is defined in part 3.
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, e.g. all
digital channels on a specific cable system.
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.
Repeater: repeater is an equipment which allows to receive a DVB-T signal and to re-transmit it. It does not allow to
change the TPS bits and thus the cell_id.
reserved: term "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. Unless otherwise specified within the present document all "reserved" bits shall
be set to "1".
reserved_future_use: term "reserved_future_use", when used in the clause defining the coded bit stream, indicates that
the value may be used in the future for ETSI defined extensions. Unless otherwise specified within the present
document all "reserved_future_use" bits shall be set to "1".
section: section is a syntactic structure used for mapping all service information defined in the present document into
ISO/IEC 13818-1 [1] TS packets.
service: sequence of programmes under the control of a broadcaster which can be broadcast as part of a schedule.
service_id: unique identifier of a service within a TS.
Service Information (SI): digital data describing the delivery system, content and scheduling/timing of broadcast data
streams etc. It includes MPEG-2 PSI together with independently defined extensions.
subcell: subcell is a geographical area that is part of the cells coverage area and that is covered with DVB-T signals by
means of a transposer. In conjunction with the cell_id the cell_id_extension is used to uniquely identify a subcell.
sub_table: sub_table is 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.
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".
