• 8 Partners all over Europe

• Goal is to develop new Hybrid Radio scenarios for mobile, car and domestic use-cases

• Development of radio service access APIs for Android, iOS and Web

• Development of an overlay network for metadata and usage data distribution

Client libraries

DAB-Multiplex (DAB/IP)

FIC-Packets MSC-Packets

Native C++ IRT DAB Libraries

OMRI Application (Android, iOS and JavaScript)

JNI Layer for Android

Swift/C++ Layer for iOS

WEBAssembly/emscripten with

OMRI API

● Open Mobile Radio Interface

● Java based API for radio centric applications

● Implementations:○ Android : Ready ○ iOS: In work○ HTML/JS: 1st prototype

player is ready to test

● Technology agnostic

● High- and low-level access to radio data

● OMRI - ETSI TS 103632 V1.1.1

Why not use DAB+ as format for IP radio?

Seite 8

● DAB multiplexes contain all important audio and data services (not only MP3/AAC Audio)

● Completely self contained stream

● DynamicLabel+ is attached to the audio data (PAD) and perfectly in sync. esp. for the Item.running and Item.toggle information

● Slideshow is usually also attached to the audio data (PAD) and also perfectly in sync.

● Announcements/Warning/Traffic signalisation “in Band” with standardized means.

● Each single service is taken from the existing DAB+ multiplex of the broadcaster.

● Service following (DAB <-> IP) gets much more easier (no Audio processing/correlation)

● Application developers use DAB+ only

Metadata platform

12

● Metadata importer for RadioDNS, DL+, ICY-Tag, WorldDAB-SPI, Radioplayer

● REST APIs for applications for service list, detailed search and personalisation queries

● Completely Docker based deployment.

● Next goals: Developing towards a federated system.

Query has two parts:

1. Genre, Geo information

2. Detailed query

(1) is used to discover best node

matches in the global node list

Local Search Node Index

1 Genre=Rock, Region=Bavaria

2 Genre=Pop, Region=NRW

3 Genre=Rock, Region=Bavaria

Query „Genre=Rock, Region=Bavaria“

Privacy preserving usage data collection

• Noise will be added to the usage data at client side.

• Broadcasters get the right answer but not single personal information

• HRADIO uses the RAPPOR (Randomized Aggregatable Privacy-Preserving Ordinal

Response) algorithm from Google.

Summary

Seite 19

TF-OMRI

• The HRADIO client libraries work fine, covering Android and JavaScriptthe iOS versions are under development.

• DAB over IP is a way to bring “real” radio services over IP (radio is morethan just the MP3 audio).

• The metadata platform is in a good shape and interesting things will come (federation and privacy preserving usage data collection)

• Upcoming pilot phase will show integrated clients for mobile and car.

This project received funding from the European Union’s Horizon2020 research and innovation programme under grant agreement no. 761813
