If You are like minded please sign this IARBA Petition and join us in asking the Minister and the ACMA
to reverse the previous governments unfair ban on new entries to Digital radio. With the inclusion of DRM
theres plenty of room for left out community stations narrowcast and narrowband and new entrants.

Stephen Conroy

DEPUTY LEADER OF THE
GOVERNMENT IN THE SENATE

Canberra ACT 2600
Dear Sir,
We the digitally undersigned ask that in the interests of media diversity, fairness and good planning that you reverse the the previous governments unfair ban on new entries into Digital radio.
We ask that you consider a two-tiered Digital Radio implementation that includes the DRM Standard so that country areas will not be left out of access to Digital Radio. As you may be aware DAB Plus performs poorly outside metropolitan areas.
We ask that DRM be included both for those broadcasting stations left out of current DAB Plus proposals: existing community stations, narrowcasters, narrowband stations and also that it be included for new entrants.
We also ask that in any strategy that your department undertakes to promote Digital Receivers, that any such promotion includes those models that can receive both the DAB Plus and DRM Standards.
DRM can fit 8 CD-quality stations into the same amount of bandwidth that DAB uses. DRM is the worlds only, open standard, universal, digital on-air system.
Peter Senger, Chairman of DRM: "DRM is a great way to enjoy not only international radio stations, but also some local and national radio. In many countries, particularly those with large rural areas, the combination of DRM and DAB gives broadcasters a tailor-made way to upgrade to digital radio and give their listeners access to a greater range of stations than ever before."

DRM: Technical Aspects of The On-Air System
Digital Radio Mondiale (DRM) is the universal, openly standardised, digital radio system for short-wave, medium-wave and long-wave - digital radio for the radio frequencies below 30MHz. It has been endorsed by the ITU, and is standardised as ETSI ES 201 980.
DRM has near-FM sound quality plus the ease-of-use that comes from digital transmissions. The improvement over AM is immediately noticeable. DRM can be used for a range of audio content, and has the capacity to integrate text and data. This additional content can be displayed on DRM receivers to enhance the listening experience.
DRM uses the existing AM broadcast frequency bands and is designed to fit in with
the existing AM broadcast band plan, based on signals of 9 kHz or10 kHz bandwidth.
It also has modes requiring only 4.5 kHz or 5 kHz bandwidth, and modes that can take advantage of wider bandwidths - 18 kHz or 20 kHz - allowing DRM to operate alongside AM transmissions in every market of the world.
The DRM system uses COFDM (Coded Orthogonal Frequency Division Multiplex). This means that all the data, produced from the digitally encoded audio and associated data signals, is shared out for transmission across a large number of closely spaced carriers. All of these carriers are contained within the allotted transmission channel. Time interleaving is applied in order to mitigate against fading. Various parameters of the OFDM and coding can be varied to allow DRM to operate successfully in many different propagation environments - the selection of the parameters allows transmissions to be planned that find the best combination of transmit power, robustness and data capacity.
The DRM system uses MPEG 4 HE AAC v2 for mixed programming providing high quality at low data rates. In addition, CELP and HVXC coders are available to provide speech-only programming at even lower data rates.
In 2005, the DRM Consortium decided to extend the DRM system to operate in all the broadcasting bands below 120 MHz. This range includes:
* 47 MHz to 68 MHz (Band I) allocated to analogue television broadcasting;
* 65.8 MHz to 74 MHz (OIRT FM band)
* 76 MHz to 90 MHz (Japanese FM band)
* 87.5 MHz to 107.9 MHz (Band II) allocated to FM radio broadcasting.
This system extension has the internal project name DRM+. The DRM Consortium
is now preparing to test and verify the design of DRM+ prior to standardisation
as a revision to the existing DRM System specification, ETSI ES 201 980.

Frontier Silicon Upgrades DAB Module to Enable DAB+ Receivers for Australian Digital Radio Launch
NewswireToday - /newswire/ - Sydney, Australia, 03/26/2008 - As radio broadcasters in Australia prepare for the launch of digital radio services using the enhanced DAB+ standard, Frontier Silicon has unveiled its latest receiver: Venice 5.1, a DAB+ version of the world’s most widely used digital radio module.
As radio broadcasters in Australia prepare for the imminent launch of digital radio services using the enhanced DAB+ standard, Frontier Silicon has unveiled its latest receiver: Venice 5.1, a DAB+ version of the world’s most widely used digital radio module.
The introduction of Venice 5.1 coincides with this week’s Australian Broadcasting Summit in Sydney, where there will be debates on the future direction of digital radio, specifically on the progress of digital broadcasting trials and the management of its roll-out.
Frontier Silicon CEO Anthony Sethill commented, “With the launch of DAB+ in Australia this year, we have taken the strategic decision to develop the Venice 5.1 module so that our customers are ready to supply digital radios during the second half of 2008 as the market develops.” He added, “The availability of a good range of receivers is a prerequisite for the successful launch of DAB+. Since we already have over 50 customer designs using the Venice 5.0 module for existing DAB regions around the world, we know that these can be quickly adapted for DAB+ reception using Venice 5.1. This will ensure that retailers can swiftly stock a line up of attractive DAB+ products as broadcasters roll out new services.”
Daniel Todd, managing director of Bush Australia, said, “The Bush brand has already enjoyed considerable success in the European DAB market and we intend to build on this in Australia as DAB+ launches. With the aggressive launch plan for DAB+ in Australia that is being implemented this year we are very excited about the prospects for this new category of audio products.”
In 2007 Frontier Silicon supplied over 80 percent of DAB solutions used worldwide, with the Venice 5.0 module forming the majority of shipments. Designed to be electro-mechanically compatible with this popular module, Venice 5.1 gives audio manufacturers the ability to quickly release a range of DAB+ capable products based on existing radio designs.
Venice 5.1 can be used as either the main controller in a tabletop or clock radio, or as a serially-controlled slave in a micro Hi-Fi or other audio system. The module supports DAB+/DAB and also FM-RDS.
Frontier Silicon is the leading supplier of digital and RF integrated circuits and modules for digital audio products. Established in 2001 as a privately funded fabless semiconductor company, it has over 160 employees and is headquartered in Watford, England, with design centres in Cambridge and Dublin, and branch offices and technical support representatives in Hong Kong, China, Korea and Japan.

Australia will have to wait for digital radio, despite plans for complete digital television coverage by 2013.
The switchover to digital TV would be complete by December 31, 2013, federal Communications Minister Stephen Conroy told the Australian Broadcast Summit in Sydney.
At the summit, he announced a $37.9 million strategy to drive the digital transition.
But Senator Conroy told broadcasters that a policy announcement on digital radio was still under discussion within federal cabinet.
\"This is a very tough set of economic circumstances the government is in. People shouldn\'t underestimate the challenges we have here at the moment,\" he said.
\"I\'m still engaged in discussions with my colleagues about digital radio, I\'m just not able at the moment to make any announcement about that.\"
Senator Conroy said the announcement of new money for digital television should bring joy to broadcasters.
\"The analogue to digital switchover could well be the largest change on the national scale since the introduction of decimal currency in 1966,\" Senator Conroy said.
\"It will affect every household and every TV receiver in the nation, including those in VCRs and other recorders.\"
The government has allocated $1 million over two years to research digital reception problems.
It has also allocated $4.8 million for a digital tracker to assess issues such as public awareness of the switchover, intention of households to convert and actual conversion rates.
The sum also encompasses $8.5 million to the Australian Communications and Media Authority to undertake switchover-related projects and $16.9 million for the digital switchover taskforce, Senator Conroy said.
The taskforce will coordinate the switchover with the Department of Broadband Communication and the Digital Economy.
\"The government digital switchover taskforce ... will work with the industry advisory group on a range of issues, including the provision of reliable information to consumers when purchasing digital equipment,\" Senator Conroy said.
The first meeting of the advisory group would convene on April 9 this year, he said.
\"The Australian government is committed to digital television and this funding will help drive a smooth transition,\" Senator Conroy said earlier on Wednesday.
