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 WorldDAB, an organization with members drawn from broadcasting
organizations and telecommunication providers together with companies from the professional and consumer
electronics industry.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

1 Scope
The present document describes the minimum requirements for digital radios, both domestic and in-vehicle, and the
necessary test methods that lead to compliance with the requirements. It may be used as the technical basis for a Digital
Radio Certification Mark scheme. A Digital Radio Certification Mark is designed to be used on product packaging and
provides an easily recognized mark to correspond to public information campaigns on the necessary requirements for
consumers to make a switch to digital radio. Manufacturers are, of course, free to include additional features or
increased performance compared to the minimum requirements specified in the present document.

4 Digital Radio Certification Mark
The present document comprises the requirements and test specifications by which radio receivers can qualify to carry a
Digital Radio Certification Mark ("the Mark"). The purpose of the Mark is to ensure that consumers can readily identify
products which are suitable for reception of digital radio services and which provide features at a sufficiently high level
of performance to ensure that the product meets the criteria set out for a switchover process and beyond. The
requirements are based on the design of DAB transmission networks, which are the result of internationally agreed
coverage planning, and essential user features that present digital radio as a desirable yet affordable product.
In order to qualify for use of the Mark, products shall meet the minimum requirements set out for the type of product,
either:
• Minimum requirements for domestic digital radio receivers (see clause 5); or
• Minimum requirements for in-vehicle digital radio receivers (see clause 6).
Products are considered to consist of a core technology - that is a chip or module that may be common to many
products - and displays, antennas, power supplies, casework, etc., which in combination are specific to a particular
product model.
In order to prove compliance against the minimum requirements, products shall pass both of the test specifications,
below:
• Test specification for core technology (see clause 7).
• Test specification for products (see clause 8).
The test specification for core technology is designed to explore all aspects of the minimum requirements, whereas the
test specification for products is designed to explore how the core technology performs when integrated into the
product.
