The present document establishes a standard method for transporting Service components (audio and data) produced by
Service providers at their own studios to the DAB multiplexing equipment located at the Ensemble provider's centre.
The present document is applicable to Collection Networks used in a DAB System. It describes the characteristics of a
signal suitable for transporting Service Components, Service Information and control data between a Service provider
and an Ensemble provider. The interface is suitable for use on a number of different physical media and
telecommunication networks. Provision is made for the inclusion of appropriate error detection and correction and for
the management of network transit delay.
This version of the present document has been aligned to V2.1.1 of ETSI EN 300 401 [1], by adding control for User
Application information.

The present document establishes a standard method for transporting Service components (audio and data) produced by Service providers at their own studios to the DAB multiplexing equipment located at the Ensemble provider's centre. EN 300 401 [1] established a broadcasting standard for a DAB system. Broadcasters who implement DAB networks require methods for transporting DAB signals, or the component parts of a DAB signal, between studios, where the programme or data service originates, and the transmitter sites from which the signal will be radiated. The network of circuits connecting the studios to the Ensemble provider's ensemble multiplexer is generally known as the Collection Network. The network of circuits connecting the ensemble multiplexer to the transmitters is generally known as the Distribution Network.

Specification of the DAB Multimedia Object Transfer (MOT) protocol.

REN/JTC-DAB-37

Applies to broadcasting of digital audio signals in any frequency band from 30 MHz to 3000 MHz, to mobile, portable and fixed receivers. For satellite and terrestrial broadcasting, simple antenna receivers are used. The EN for the consumer hardware is CENELEC s task.

Specifies an interface which allows digital processing equipment for DAB to be connected to RF modulation equipment at DAB transmitter sites.

Specifies an interface which allows broadcasters, who are producing a DAB programme or data service component, to transmit this DAB component to the multiplex operator responsible for building the full signal.

Specifies an interface which allows broadcasters or multiplex operators, who are generating a complete DAB ensemble, to transport the ensemble data between the DAB ensemble multiplexer and the transmitter network.
