Radio Broadcasting Systems - Digital Audio Broadcasting (DAB) to mobile, portable and fixed receivers
The present document establishes a broadcasting standard for the Digital Audio Broadcasting (DAB) system designed
for delivery of high-quality digital audio and video programmes and data services for mobile, portable and fixed
reception from terrestrial transmitters in the Very High Frequency (VHF) frequency bands as well as for distribution
through cable networks. The DAB system is designed to provide spectrum and power efficient techniques in terrestrial
transmitter network planning, known as the Single Frequency Network (SFN) and the gap-filling technique. The DAB
system meets the required sharing criteria with other radiocommunication services.
The present document defines the DAB transmission signal. It includes the coding algorithms for multiplexing of audio
and video programmes and data services, channel coding and modulation. Provision is also made for transmission of
additional data services which may be programme related or not, within the limit of the total system capacity. The
present document provides information on the system configuration which includes information about the ensembles,
services, service components and linking of them.
The present document describes the nominal characteristics of the emitted DAB signal. The aspects related to the
receiver design are outside the scope of the present document.

Ta dokument določa standard radiodifuzije za sistem digitalne zvokovne radiodifuzije (DAB), zasnovan za zagotavljanje visoko kakovostnih digitalnih zvokovnih in video programov ter podatkovnih storitev za mobilni, prenosni in fiksni sprejem za zemeljske oddajnike v frekvenčnih pasovih VHF ter za distribucijo prek kabelskih omrežij. Sistem digitalne zvokovne radiodifuzije je zasnovan za zagotavljanje spektra in energijsko učinkovitih tehnik pri načrtovanju omrežij za zemeljske oddajnike. To je poznano kot enofrekvenčno omrežje (SFN) in tehnika zapolnjevanja vrzeli. Sistem digitalne zvokovne radiodifuzije izpolnjuje zahteve za skupno rabo z drugimi radiokomunikacijskimi storitvami.
Ta dokument določa prenosni signal sistema digitalne zvokovne radiodifuzije. Vključuje kodirne algoritme za multipleksiranje zvokovnih in video programov ter podatkovnih storitev, kodiranje kanalov in modulacijo. Predviden je tudi prenos dodatnih podatkovnih storitev, ki so lahko povezane s programom ali pa ne, in sicer v okviru skupne zmogljivosti sistema. Ta dokument podaja informacije o sistemski konfiguraciji, kar zajema podatke o kompletih, storitvah, komponentah storitev in njihovo povezovanje. Ta dokument opisuje nominalne značilnosti oddanega signala digitalne zvokovne radiodifuzije. Vidiki, povezani z zasnovo sprejemnika, ne spadajo na področje uporabe tega dokumenta.

This draft European Standard (EN) 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), and is now submitted for the combined Public Enquiry and Vote phase
of the ETSI standards EN Approval Procedure.
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

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 ETS 300 401 [i.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.
With respect to the previous version of ETSI EN 300 401 published in June 2006, the present document contains
several refinements to the DAB system. These refinements were performed and agreed by the WorldDAB Forum and
include the following areas:
• additional rules and guidance on use of certain features;
• addition of MCI and SI FIGs to enhance receiver behaviour;
• removal of some obsolete service information features;
• removal of transmission modes II, III and IV;
• DAB audio (MPEG layer II) details moved to a separate ETSI document.

Foreword
This European Standard (EN) 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 ETS 300 401 [i.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.
With respect to the previous version of ETSI EN 300 401 published in June 2006, the present document contains
several refinements to the DAB system. These refinements were performed and agreed by the WorldDAB Forum and
include the following areas:
• additional rules and guidance on use of certain features;
• addition of MCI and SI FIGs to enhance receiver behaviour;
• removal of some obsolete service information features;
• removal of transmission modes II, III and IV;
• DAB audio (MPEG layer II) details moved to a separate ETSI document.

1 Scope
The present document establishes a broadcasting standard for the Digital Audio Broadcasting (DAB) system designed
for delivery of high-quality digital audio and video programmes and data services for mobile, portable and fixed
reception from terrestrial transmitters in the Very High Frequency (VHF) frequency bands as well as for distribution
through cable networks. The DAB system is designed to provide spectrum and power efficient techniques in terrestrial
transmitter network planning, known as the Single Frequency Network (SFN) and the gap-filling technique. The DAB
system meets the required sharing criteria with other radiocommunication services.
The present document defines the DAB transmission signal. It includes the coding algorithms for multiplexing of audio
and video programmes and data services, channel coding and modulation. Provision is also made for transmission of
additional data services which may be programme related or not, within the limit of the total system capacity. The
present document provides information on the system configuration which includes information about the ensembles,
services, service components and linking of them.
The present document describes the nominal characteristics of the emitted DAB signal. The aspects related to the
receiver design are outside the scope of the present document.

Foreword
This European Standard (EN) 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 ETS 300 401 [i.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.
With respect to the previous version of ETSI EN 300 401 published in June 2006, the present document contains
several refinements to the DAB system. These refinements were performed and agreed by the WorldDAB Forum and
include the following areas:
• additional rules and guidance on use of certain features;
• addition of MCI and SI FIGs to enhance receiver behaviour;
• removal of some obsolete service information features;
• removal of transmission modes II, III and IV;
• DAB audio (MPEG layer II) details moved to a separate ETSI document.

1 Scope
The present document establishes a broadcasting standard for the Digital Audio Broadcasting (DAB) system designed
for delivery of high-quality digital audio and video programmes and data services for mobile, portable and fixed
reception from terrestrial transmitters in the Very High Frequency (VHF) frequency bands as well as for distribution
through cable networks. The DAB system is designed to provide spectrum and power efficient techniques in terrestrial
transmitter network planning, known as the Single Frequency Network (SFN) and the gap-filling technique. The DAB
system meets the required sharing criteria with other radiocommunication services.
The present document defines the DAB transmission signal. It includes the coding algorithms for multiplexing of audio
and video programmes and data services, channel coding and modulation. Provision is also made for transmission of
additional data services which may be programme related or not, within the limit of the total system capacity. The
present document provides information on the system configuration which includes information about the ensembles,
services, service components and linking of them.
The present document describes the nominal characteristics of the emitted DAB signal. The aspects related to the
receiver design are outside the scope of the present document.
