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, ETSI EN 300 401 [1], for DAB (see note 2) which now has worldwide acceptance.
NOTE 2: DAB is a registered trademark owned by one of the Eureka Project 147 partners.
The DAB family of standards is supported by World DAB, an organization with members drawn from broadcasting
organizations and telecommunication providers together with companies from the professional and consumer
electronics industry.

1 Scope
The present document establishes an optional extension to the broadcast standard for Digital Audio Broadcasting
(DAB) system.
The Filtered Information Service (FIS) is a data application that allows service providers to deliver information to
groups of receivers with configurable filters, for example, text language, model number, date of registration, etc. The
XML framework and transport specification are defined.

4 Introduction
The Filtered Information Service (FIS)is an application used to send messages to suitably equipped DAB devices via
the broadcast radio network. It may be used by a radio manufacturer, car manufacturer or third-party to disseminate
information to their clients. The FIS allows the information to be identified by company defined filters in order to target
particular information to particular device groups. The information is primarily text based, but images may also be
provided.
FIS use cases can be very diverse, from kitchen radios to a company car fleet.
EXAMPLE 1: A kitchen radio maker provides news that updated software is available for download via an
internet address, or that it has new models available.
EXAMPLE 2: An OEM wishes to reach vehicle owners about important information such as a dealer recall but
has lost contact with some owners due to vehicle resale; the information may be targeted at a
particular range of vehicles based on the model year, transmission system, etc.
EXAMPLE 3: A car rental company provides general messages to groups of vehicles based on their location, age,
etc. and specific details of individual rental issues which are only displayed in the corresponding
vehicle.
Since the FIS uses the DAB broadcast network, there is no need for special infrastructure to transmit the FIS
information. The broadcaster or network operator embeds messages into the DAB broadcast according to the defintions
provided by the present document. The receiver implements security and message filtering mechanisms in order to
display the appropriate information. It is not necessary for the receiver to have continuous reception of the FIS, because
the information is cyclically repeated and cached in the receiver.
Each FIS has a unique company identifier, called a key, which allows receivers to focus on only the messages of
interest. Messages may be provided securely to end-user devices by the use of encryption. A FIS consists of an XML
document and may include additional image files.
An overview of the FIS is provided in figure 1.

Figure 1: Overview of the FIS
An entity can direct a message to a dedicated subset of its own receivers by defining and using filters linked to the
product characteristics that the company wants to address.
EXAMPLE 4: An OEM can direct messages to specific car models from specific registration periods.

It is the company responsibility to define its own filters in a filter definition file. With this file, filters can be applied to
messages in the broadcast XML file. The receiver will display the message only if associated filters are compliant with
the receiver configuration file.

Figure 2: Example of use of the filter definition file
Messages from a particular service provider are grouped together into a FIS. The FIS may be encrypted to provide
additional security, but the encryption method is not standardized. Encryption is not recommended when the FIS is
directed to multiple receiver brands, for example, when a car rental company wants to send messages to the entire fleet;
in this case different makes and models of cars with different receiver brands all need to be able to decode the FIS.
5 Filtered Information Service data
5.0 Introduction
A FIS consists of a set of messages, encoded as an XML file, and supporting data files, such as images, carried in an
MOT carousel (see ETSI EN 301 234 [2]). The MOT carousel is transported using packet mode with additional FEC
(see ETSI EN 300 401 [1]). Every file within the MOT carousel is identified with the company identifier to provide the
first level of message selection in the receiver.
All XML documents defined in the present document shall use the ISO/IEC 10646 [5] character set using UTF-8
character encoding.
Text sections (attributes or elements) shall not use the following reserved XML characters:
& " '
These characters shall be encoded using the predefined entity references & " &apos respectively.
The reserved XML characters < > may be used in the title and body elements. In all other text sections they shall
be encoded using the predefined entity references < > respectively.

5.1 FIS element
This is the root element of the FIS document and can contain zero or more of the following elements:
• message.
Its attributes are detailed below:
Attribute Description Type Status
key
Company identifier for entity providing the xs: unsignedInt Required
information.
version
Indicator for changed content; shall be incremented xs:unsignedShort Required
by one for every new version of the fis element,
modulo 65536.

5.2 Message element
The message element can contain the following elements:
• text
• picture
• validity
• geolocation
• filters
As a minimum, one text element and one validity element shall be specified for each message. The validity
element specifies the lifetime of the message in the receiver.
Its attributes are detailed below:
Attribute Description Type Status
identifier
Unique identifier xs:unsignedInt Required
priority
Message priority chosen from: xs:enumeration Optional,
critical, important, major, normal, minor, low defaults to
"normal"

The identifier attribute shall be set to a unique value for each message, in the range 0 to 4 294 967 295.
A message is created by using a new identifier.
A message is deleted in the receiver only when its validity has expired, even if it is no longer transmitted. The
service provider shall therefore ensure that no identifier is reused until after the message has expired.
Only the validity element may be updated, see clause 5.5: this allows a message to have its validity extended or
curtailed. If any other content is changed, a new message with a different identifier shall be created; the old
message should continue to be transmitted with an expired validity to ensure its deletion in receivers.
Not all messages will have the same importance: some may be really important, for example, if they concern a safety
issue, others may be less important, for example, those that concern only promotion.
The FIS has 6 levels of messages:
• 0: critical
• 1: important
• 2: major
