The DAB (Digital Audio Broadcasting) digital radio sector has responded robustly to recent negative opinions and reports on the technology and called for action to make the switchover from analogue transmission a reality, writes Kevin Hilton.

The call for action was made at the General Assembly of the WorldDMB (WDMB) Forum, which defined the DAB and DAB+ digital radio standards and the DMB (Digital Multimedia Broadcasting) format for radio and mobile reception.

The meeting was held in Belfast at the end of October. It coincided with the EBU's Digital Radio Conference and Festival of Radio - Making Connections, organised jointly by Irish broadcasters BBC Northern Ireland and RTE.

Broadcasters and manufacturers took the opportunity to respond to criticism of the slow take-up of DAB, particularly in the UK. Despite the British government setting 2015 as the date for the digital switchover to begin, critics are not convinced that DAB will fully replace FM broadcasts. Digital radio also faces serious competition from the internet and multimedia, which is seen as offering more choice and better technical quality.

In the keynote address Hossein Yassaie, chief executive of Imagination Technologies, parent group of leading digital receiver manufacturer PURE, called for a unified strategy to ensure that digital radio proliferated across Europe. He added that the launch of DAB in Germany, France and Italy was crucial for the "health" of the digital radio market.

Yassaie called broadcast radio the "most efficient and greenest method of reaching a large population", particularly for listeners in cars and on the move in general. This point was backed up with analysis presented by Simon Mason, head of technical development at transmission company Arqiva. Mason presented research showing that 3G/4G are not economically or technically realistic alternatives to radio for delivering programmes to the mobile market.

Tim Davie, director of BBC Audio and Music, said that simulcasting digital and analogue transmissions was a major burden to broadcasters and that this "bump in the road" need to be deal with soon. He continued that a "clear roadmap" was necessary so European broadcasters could plan for the future confidently.

A possible interim measure that was discussed is a hybrid system combing DAB, IP and FM that could be used leading up to a full switchover.

The president of WDMB, Jorn Jensen (pictured), commented that the General Assembly had seen "real energy and commitment" from delegates this year. He said the DAB industry need to carry on cooperating to ensure the successful rollout of the technology internationally.

"In 2011 WDMB will continue to work together with our members to support France, Germany and Italy, as well as strengthen our already valuable communication with the automotive industry," Jensen concluded.


New chip puts DAB on iPod docks

The beleaguered DAB range of digital radio standards received a boost at CES with the launch of new technology that brings the formats to a wide variety of domestic audio systems, writes Kevin Hilton.


Radio bosses bullish on DAB/DAB+

DAB and DAB+ are the future for European digital radio, according to key figures in the industry who addressed the Radiodays Europe conference in Berlin earlier this week (17-19 March).


Spreading the love for DAB service following

Digital Radio UK and Arqiva have published a report on service following, based on trials carried out in the southeast of England last year. The results show that broadcasters and radio manufacturers have to co-operate further to create seamless networks in the build-up to an analogue switchover.


Open formats point way for small-scale DAB

Small-scale DAB stations could be a way ahead for community and smaller local radio station transmission, according to an Ofcom report. It is based on findings from trail that ran in Brighton between September 2012 and January 2013.


Service following - DAB's missing link

As the analogue radio switch-off draws closer, broadcasters and regulators are coming to terms with creating a seamless digital network, especially for in-car listening. Service following is at the heart of this and Digital Radio UK is among the organisations dealing with its implementation.

Germans turn on to DAB

Germany made the move to digital radio on 8th August, when 27 transmitters across the country brought DAB (digital audio broadcasting) to all the country’s major cities, as well as along its motorways, writes Kevin Hilton.
