Intellectual Property Rights
Essential patents
IPRs essential or potentially essential to normative deliverables may have been declared to ETSI. The information
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 (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Trademarks
The present document may include trademarks and/or tradenames which are asserted and/or registered by their owners.
ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no
right to use or reproduce any trademark and/or tradename. Mention of those trademarks in the present document does
not constitute an endorsement by ETSI of products, services or organizations associated with those trademarks.
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 [13], 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.
The RadioDNS Project was established in 2010 to standardize the combination of broadcast radio systems with
additional applications, content and meta-data delivered over fixed or mobile IP networks. The project produced a
specification using DNS to locate the broadcaster's Internet domain which is in use worldwide, and now standardized as
ETSI TS 103 270 [18]. RadioDNS operates the authoritative name servers for the radiodns.org domain, and has
members drawn from broadcasting organizations, manufacturers and service providers.
NOTE 3: "RadioDNS Hybrid Radio" and the RadioDNS Hybrid Radio logo are registered trademarks of
RadioDNS Limited, a not-for-profit company owned by its members.

In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and

1 Scope
The present document defines the XML schema data model for Service and Programme Information (SPI) and methods
for delivery by broadcast digital radio - DAB and DRM - and IP.
In respect to the previous version of the present document, provision is added for client authorisation for IP delivered
metadata. The use of the present document allows content to be created once by the service provider for delivery by
both mechanisms and allows manufacturers to implement devices with many common elements.
It is envisaged that this data format could be used both for transmitting service and schedule data to SPI applications on
devices and as the basis for exchanging information between service providers, network operators and content
providers.
