Solving the Medium-Wave Problem

Ruxandra Obreja

It’s undeniable that the whiff of decline has enveloped AM in the past two decades. The reasons are well-known: Analog medium wave doesn’t always deliver the best sound, it can suffer from interference, it can behave annoyingly different by day and night and even by season. Medium wave mainly appeals to a maturing population (a global phenomenon, considered shameful by some!) using aging receivers (this is bad!).

Analog medium-wave broadcasting also needs quite an infrastructure and deep pockets for the electricity bill.

On the other hand, medium wave is that middle sister that delivers by giving excellent regional coverage over hundreds or (overnight and if the ionosphere behaves) even thousands of kilometers, whereas FM goes up to roughly 200 kilometers and digital DAB+ to half of that.

Medium wave is not only a regional but also an excellent local coverage solution. In Australia 33% of the public broadcaster ABC’s local transmitters broadcast in AM and 11 50 kW transmitters are serving the mainland capital or big cities. Medium wave covers large areas and reaches small far-flung communities for whom, even in developed countries, medium wave and FM still provide the first source of information.

Besides, medium wave with its reach, availability outdoors and on the go, is a fallback solution in times of emergency or simply a good standby solution when other platforms or services are unavailable (broadband, satellite, 4G or the mythical 5G).

THE SOLUTION

Recently cricket fans were able to enjoy an open-air demonstration of three different DRM programs on one frequency ahead of an important match in Bangalore. The fans also received data (stock exchange values) available on radio screens. This demonstrated that digital DRM is a game changer for medium wave.

In DRM the crackling audio disappears as sound is as good of that on FM. The electricity consumption and costs decrease, the spectrum is trebled and reception, even in cars (as available in over 1.5 million cars in India currently) is excellent, too.

If it is so good then why isn’t DRM medium wave conquering the world faster? Maybe it’s about confidence in a new platform. Broadcasters and governments need to market DRM digital radio once signals are on air in their countries.

As for receiver availability and their costs, let us remember how many receivers were on sale in the 1970s when FM was taking over the world. Nowadays, many listeners consume radio in their cars rather than sit in front of a retro looking wooden box. Digital receivers (DRM alone or DRM/DAB+) are a reality and a bigger push for digital would help with volumes sold thus bringing down the prices.

Radio, and therefore medium wave, can and should survive digitally. Digital radio must be an enabler of audio content and information while preserving its ubiquitous and unmatched advantage of providing a service for all.

For that, a bit of imagination, trust and, last but not least, some long-term investment is necessary. Because medium wave is still worth it!

RFmondial Launches Multiplexed DRM for FM Band

RFmondial has added a new member to its line of LV-series of DRM modulators and exciters with an advanced multiplexed DRM modulation designed specifically for the FM band.

This new DRM system allows for the parallel generation and transmission of up to six pure digital DRM channels, or in combined analog and digital “simulcast” mode, on one traditional analog FM channel or up to four DRM channels.

Stefan Galler, managing director of RFmondial, said the new DRM modulators give “the ability to freely mix and combine analog and multiple digital DRM signals, in adjacent channels, with individually varying power levels, supporting single frequency networks, allows broadcasters, network regulators and frequency planners a new dimension of possibilities for planning and operation of digital radio networks.”

Fraunhofer IIS ContentServer R7 digital radio head-end technology for DAB+ and DRM

Fraunhofer DRM ContentServer Multiplex Editor

Fraunhofer IIS introduces the latest major release of its professional ContentServer head-end technology for Digital Radio DAB+ and DRM (Digital Radio Mondiale): Version R7 of this flexible and highly reliable solution is now readily available in products from Fraunhofer’s OEM partners. The new DAB/DRM Content Server R7 enables broadcasters to put audio content and attractive data services on air with ease while benefiting from the latest standard upgrades and a range of new productivity features.

New features that come with the Fraunhofer DAB/DRM ContentServer R7 include, for instance, automatic Audio Loudness Normalization and Monitoring as well as additional IP-based Audio Streaming Source Interfaces.

The Content Server’s internal audio encoders now support loudness normalization that amplifies or attenuates the incoming audio to obtain and maintain the target loudness level specified in Loudness Units relative to Full Scale (LUFS). This feature is based on Fraunhofer Sonamic technology and is especially useful if the loudness of all audio services within the generated multiplex should be the same or if an audio source provides audio at varying loudness levels.

Additional input interfaces for IP-based audio sources now comprise Livewire/Ravenna /AES-67-based raw audio streams as well as consumer-type Icecast/SHOUTcast streams. The Content Server can also serve as an end point for RTP-based audio bridges to accept uncompressed or compressed (e.g. AAC) audio streams without the need for external devices. Audio level monitoring, audio source remote listening through HTML5 browsers and silence/clipping detection are supported, while powerful concealment strategies minimize the impact of packet losses on the contribution network.

In addition, the Content Server R7 includes the following new functionalities:

• Interactive graphical system status overview: shows the status of all system components in a schematic graphic overview, with direct links to the relevant documentation, logging and editor pages.

• EWF with CAP import: EWF (Emergency Warning Functionality) is the early warning dissemination mechanism for both DAB and DRM. It consists of alarm signaling plus an emergency program broadcast composed of an audio announcement and multi-lingual Journaline text. The standardized Common Alerting Protocol (CAP) or its derivatives (such as MoWaS in Germany) are used to distribute emergency warnings from a central authority to the broadcasters. The ContentServer R7 now has a native CAP import interface and automatically creates the EWF alarm announcements and EWF program content for DAB/DRM transmissions.

• JSON/XML RPC management and data interfaces: remote procedure calls (RPC) based on JSON (JavaScript object notation)/XML (extensible markup language) enable modern configuration and monitoring, announcement and reconfiguration triggers, linkage set activations as well as instant provision of content updates such as Dynamic Label/Text Messages, Journaline text pages and Slideshow images to the ContentServer.

• Audio Cross-Redundancy: Deploying a new Smart Silence Detection technology, it ensures perfectly valid multiplex outputs from all ContentServers of a redundancy group even if a live audio input source fails. This new feature enhances the existing Backup Audio Encoding functionality, which allows to define backup audio sources such as pre-uploaded file sets to serve as a ‘last resort’ in case of fully failing audio live inputs.

• EDI Switch for DAB: this built-in feature ensures that all peers in a ContentServer redundancy group output the identical multiplex data stream to downstream devices via EDI (the IP-based distribution protocol from DAB multiplexers to DAB modulators/transmitters).

• Localized multiplex output: allows multiple small-scale DAB multiplexes to be generated by a single ContentServer to enable low-cost DAB setups, for example.

• Automatic creation of playlists as Journaline pages: the list of recently played songs is derived from the Dynamic Label Plus information and accessible to the listener through Journaline.

• DAB V2.1.1 compliance: full support of DAB(+) versions V1.4.1 and V2.1.1 including OE (other ensembles) announcements, test (OE) alarm announcements and service component information (SCI). Correspondingly, Fraunhofer’s SDR based DAB receiver solutions are now also DAB 2.1.1 compliant.

• Stream monitoring: powerful tools to analyze and monitor incoming audio and Distribution and Communication Protocol (DCP)-based streams

Fraunhofer’s Content Server technology combines internal audio coding (including MPEG xHE-AAC audio coding for DRM, enabling the definition of backup audio sources), support for remote audio encoders, multimedia data management and multiplex generation with powerful redundancy features that work across remote sites. A convenient and user-friendly web interface supports configuration and system monitoring via remote access, enabling content-as-a-service operation scenarios. Its flexible configuration and out-of-the-box support for a large number of versatile interfaces for audio and content provision allows for straightforward integration into broadcasters’ and network providers’ broadcasting environments – from small-scale community stations all the way to large-scale and complex national networks.

The Content Server supports all standardized DAB+ and DRM data applications such as Text Messages/Dynamic Label and Dynamic Label Plus (DL+), Journaline, Slideshow, SPI/EPG including station logo transmission, and EWF. In addition, it is possible to insert proprietary data at various levels of the DAB/DRM protocol stack. All uploaded data is checked and broadcast only if successfully verified.

DRM for FM goes super efficient – RF Mondiale and Nautel demonstrate game -changing DRM ,FM Modulator.

At IBC during the Nautel event, RFmondial together with Nautel demonstrated its advanced multiplexed DRM modulation for the FM band, that allows broadcasters to transmit multiple DRM channels on one physical transmitter.

The newest member of RFmondial’s successful LV-series of DRM modulators and exciters allows the parallel generation and transmission of up to six pure digital DRM channels, or in combined analogue and digital „Simulcast” mode, one traditional analogue FM channel and up to four DRM channels. As explained by Stefan Galler, Managing Director of RFmondial GmbH in Hannover “using a spectrum of 600kHz one could place the FM signal occupying 200kHz in the centre and use the other 400 to carry two right and two left DRM channels or just two right or left DRM channels as DRM occupies half the FM spectrum. One DRM channel carries two to three programmes so on one transmitter, one antenna one could broadcast in pure DRM up 24 programmes, probably a bit too ambitious or one FM programme and between 12-18 DRM programmes.”

The efficiency is not just at the spectrum level but comes also from the possibility of reusing the same transmitter, the same antenna and combiner systems. Planners will appreciate that if you wanted to put two DRM channels on adjacent frequencies this was very hard and for good results you needed really to build two towers and two antennas. With this innovation using one transmission site and one antenna is possible, easier, bringing in efficiency and a degree of flexibility unknown before. In Stefan Galler’s words: “The ability to freely mix and combine analogue and multiple digital DRM signals, in adjacent channels, with individually varying power levels, supporting single frequency networks, allows broadcasters, network regulators and frequency planers a new dimension of possibilities for planning and operation of digital radio networks.”
