pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://webapp.etsi.org/IPR/home.asp).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

Foreword
This Technical Specification (TS) 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 1: 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 Eureka Project 147 was established in 1987, with funding from the European Commission, to develop a system for
the broadcasting of audio and data to fixed, portable or mobile receivers. Their work resulted in the publication of
European Standard, EN 300 401 [18], for DAB (see note 2) which now has worldwide acceptance. The members of the
Eureka Project 147 are drawn from broadcasting organizations and telecommunication providers together with
companies from the professional and consumer electronics industry.
NOTE 2: DAB is a registered trademark owned by one of the Eureka Project 147 partners.

1 Scope
The present document defines the XML schema data model for an Electronic Programme Guide (EPG) for Eureka-147
Digital Audio Broadcasting (DAB) (EN 300 401 [18]) and Digital Radio Mondiale (DRM) (ES 201 980 [23]). Within
the present document the term "DAB" is used to refer to the Eureka-147 Digital Audio Broadcasting standard. It is
envisaged that this data format could be used both for transmitting schedule data to EPG applications on receivers and
as the basis for exchanging information between broadcasters, network operators and content providers.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
Conditional Access (CA): mechanism by which the user access to service components can be restricted
data service: service which comprises a non-audio primary service component and optionally secondary service
components
ETSI

---------------------- Page: 7 ----------------------
8 ETSI TS 102 818 V1.4.1 (2008-06)
ensemble: transmitted signal, comprising a set of regularly and closely-spaced orthogonal carriers
NOTE: The ensemble is the entity that is received and processed. In general, it contains audio and data services.
Ensemble Identifier (EId): unique 16-bit code, allocated to an ensemble and intended to allow unambiguous
worldwide identification of that ensemble
eXtended Programme Associated Data (X-PAD): extended part of the PAD carried towards the end of the DAB
audio frame, immediately before the Scale Factor Cyclic Redundancy Check (CRC)
NOTE: Its length is variable.
Programme Associated Data (PAD): information that is related to the audio data in terms of contents and
synchronization
NOTE: The PAD field is located at the end of the DAB audio frame.
secondary service component: in the case where a service contains more than the primary service component, the
additional service components are secondary service components
service: in the present document the term "service" is used to refer to a "radio station" such as BBC Radio 4 or
Oneword
NOTE: In strict DAB terms this is actually a service component of a service.
service component: part of a service which carries either audio (including PAD) or data
NOTE: The service components of a given service are linked together by the Multiplex Configuration
Information. Each service component is carried either in a sub-channel or in the Fast Information Data
Channel.
Service Identifier (SId): 16-bit, 24-bit or 32-bit code used to identify a particular service

XML eXtensible Markup Language
X-PAD eXtended Programme Associated Data
4 Introduction
It is intended that the EPG will be used to provide programme listings information for both audio and data services and
as a mechanism for the user to select services, programmes and related content. A key requirement is that the EPG must
work on a range of receivers with differing display capabilities, resources and back-channel capabilities. To achieve this
a flexible structure has been defined, as shown in figure 1. The EPG data is broken down into service information
(ensembles and services) and programme information (schedules, programmes, groups and events). Additionally
programmes and events can be linked together into groups (e.g. for grouping programmes together into serials or
series).

Service information
Information about an ensemble
ENSEMBLE
Information about a service and a link to the ensemble it broadcasts on
SERVICE
Schedule information
Information about a schedule for one or more services
SCHEDULE
Information about a programme and a link to its service
PROGRAMME
Information about an event and a link to its programme
EVENT
Group information
Information about a group
GROUP
Information about a group and links to parent groups
GROUP
…
A programme links to its parent groups
PROGRAMME

Figure 1
The EPG may be delivered using the DAB or DRM broadcasting systems. The philosophy is that DAB will carry a
DAB EPG describing DAB services and DRM will carry a DRM EPG describing DRM services. In general, the DAB
and DRM EPGs are the same; however there are slight differences to the format of certain fields to deal with the
specific requirements for these two systems and signalling is provided to receivers to ensure there is no confusion.

4.1 Document structure
The EPG specification is split into 3 schemas:
• Common data types - epgDataTypes_14.xsd.
• Schedules - epgSchedule_14.xsd.
• Service information - epgSI_14.xsd.
The present document is therefore also split into three clauses with the schemas in annexes at the end of the document.
Each clause defines and describes each of the entities, elements and attributes in the respective schema.
NOTE: Some of the examples use the representation "…" to indicate possible child elements, this is not valid
XML.
4.2 XML information
4.2.1 Why XML?
Standards: XML is a well-established standard for describing structured information.
Future expandability and backwards-compatibility: An appropriately designed XML application can be expanded in
the future without breaking any previous systems. This is particularly important in this case where we are tr
