Remote Radio Monitoring System
Application Scenarios
Why Remote Realtime Radio Monitoring?
- Web-streaming and broadcast content could be different, e.g. server-side Ad serving by Internet streaming
- Local and regional stations or regional content inserts may not be online.
- Controlling and access to the broadcast signals of regional partners
- Regional restrictions for the content access via Internet
- Significant audio delays on the web-streams ->not acceptable for hybrid radio or channel detection and synchronisation
- Different standards and protocols for content access
- Law-requirements: monitoring should be on the broadcast audio and not on the internet streams
- Broadcast monitoring system cannot be easily blocked or manipulated
- Innovative radio advertisement forms using the second screen
- Access to the broadcasting meta-data, e.g. RDS

Functions of embedded server
- Power management
- Tuner management and tuner configuration
- Software decoding of broadcasting audio signals to any format, sample and bit rate
- Processing, compression and analysis of digital audio signals from tuners, local network or Internet
- Transmission of digital audio signals through a local network or remotely via Internet
- Processing and transmission of accompanying digital data, e.g. RDS (Radio Data System)
- Processing and distribution of signal- and metadata for real time monitoring or archived content analysis
- Control, retrieval and distribution of I/Q data from a single-channel SDR module
- Network and security
- Low-level REST API
Optional SDR Receiver
Additional SDR receiver for the spectrum monitoring or signal analysis, e.g. RTL-SDR or LimeSDR Mini. Data can be visualized using open source or freeware tools from local or remote SDR receivers and import to the main system via flexible API interfaces.
iROKS Mini and iROKS GPU
iROKS Mini
SDR (Software Defined Radio) only version for a limited number of channels. Complete decoding is done in the software on the processor.
iROKS GPU
SDR (Software Defined Radio) version with a GPU decoding. Entire FM decoding is done in the software on the GPU.
Cloud Server
Real-time monitoring or archive analysis of radio stations and Internet streams using open source observability platform
Flexible threshold configuration. Single view on channels and units from different locations
Single station monitoring and analysis
Real-time view of main metrics
Combination of data from different sources in a single dashboard
- broadcast data
- online streaming data
- metrics from audio analysis programms
- audience measurements
Direct access, export and publication of audio data using our software or 3rd party tools
Combination of text and numerical data
Combination of text and numerical data
Automatic Speech Recognition (ASR)
Our software can be integrated with an offline open source speech recognition toolkit that currently enables speech recognition for 16 languages and dialects – English, Indian English, German, French, Spanish, Portuguese, Chinese, Russian, Turkish, Vietnamese, Italian, Dutch, Catalan, Arabic, Greek, Farsi. We have tested English and German. This is not perfect but still very impressive. All data can be added to the database for further retrieval and analysis. It is also possible to translate the text into any other language. Text-to-speech (TTS) engine can be used to provide a spoken translated version of the stream that can be mixed to the original stream.
Alerting
Integrated alert systems with flexible rules
DTMF decoding
DTMF stands for Dual Tone Multi Frequency and used by broadcasters to mark different program sections, e.g. begin / end of news, traffic, weather or advertisement. Our system supports the DTMF decoding simultaneously on all channels. It is also thinkable to divide the listeners in groups and generates different content (e.g. news or advertisement) for the distribution in real-time for all channels.
Analytics
Listener and streaming anayltics in Google Analytics or open observability platform
- Google Analytics or Open Observability platform support
- Multi-servers, multi-streams
- Flexible metrics
- Icecast integration; HLS or DASH integration on request
- Tracking pixel for web-users
- Geolocation, geotargeting and geofencing
- Flexible proxy based on Netflix Zuul for dynamic routing, monitoring, resiliency and security
Please see our section Brodcasting Statistics in Google Analytics or Open Observability Platform for more details.
