Digital audio broadcast system - Specification of the receiver data interface (RDI)

Applies to the direct connection of one or more data application decoders to DAB (digital audio broadcast) receivers. Dedicated decoders for data, but also devices for audio post-processing and recording can be connected through the receiver data interface (RDI).

Système de radiodiffusion sonore numérique (DAB) - Spécification de l'interface de données du récepteur (RDI)

S'applique à la connexion directe de décodeurs d'application de données avec des récepteurs DAB (radiodiffusion sonore numérique). Des décodeurs spécifiques pour des applications de données, mais également des dispositifs destinés au post-traitement et à l'enregistrement audio peuvent être connectés à un récepteur DAB par l'interface de données du récepteur (RDI).

Overview

EN 62105:2002 - Digital audio broadcast system: Specification of the receiver data interface (RDI) defines the interface used to connect external data application decoders and auxiliary devices to DAB (Digital Audio Broadcasting) receivers. The published Slovenian adoption (SIST EN 62105:2003) is stated as identical to EN 62105:2002. The standard focuses on enabling direct connectivity for data decoders as well as devices for audio post‑processing and recording via the Receiver Data Interface (RDI).

Key topics and requirements

While the full standard contains the technical specification, the core themes covered include:

• Purpose of RDI - how the receiver data interface supports the delivery of data services and decoded content from DAB receivers to external equipment.
• Interoperability - requirements that promote compatibility between DAB receivers and multiple types of external decoders and peripherals.
• Supported device types - explicit accommodation of dedicated data decoders, audio post‑processing units, and recording devices connected directly to the receiver.
• Integration considerations - guidance for direct connection scenarios where one or more decoders are attached to a single receiver.
• Operational scope - applicability to receiving equipment in broadcasting environments as indicated by the ICS classifications for receiving/transmitting equipment and television/radio broadcasting.

Note: This summary does not reproduce technical parameters (electrical, mechanical, protocol details) that are contained in the full standard document.

Applications

EN 62105 (RDI) is intended for practical use in:

• Integrating data application decoders with consumer and professional DAB receivers.
• Connecting external audio processing units (equalizers, DSP modules) for improving or modifying audio output prior to distribution or recording.
• Linking recording devices to capture broadcast audio and associated data streams for archiving or content management.
• Deployments in automotive infotainment, consumer audio equipment, studio interfaces, and broadcast receiver systems requiring standardized data access.

Who uses this standard

• Manufacturer engineers designing DAB receivers and external decoder/peripheral hardware.
• Systems integrators implementing DAB-based audio and data solutions.
• Broadcast engineers and service providers specifying receiver interfaces for content distribution.
• Product compliance and QA teams ensuring interoperability across devices.

Related standards

EN 62105 complements other DAB system and broadcasting specifications and is typically used alongside broader DAB system standards and receiver performance documents to ensure complete system interoperability and compliance.
