Q2 2012 Report

Jul 2, 2012   //   by dusty   //   DB Blog  //  7 Comments

At the end of each quarter you can get an update with the latest developments and achievements of the dB Digital Broadcasting DAB trial. To automatically receive updates by email or RSS feed see our Join In page.

Q2 has been a very intense period of activity as we geared up to putting our trial on-air.

On the technical front we took delivery of all the required transmission equipment and the installation was carried out during June. Our inventory now includes transmitters from Rhode & Swartz and Harris. These are two of the leading manufacturers of DAB transmission equipment and we shall be testing the various transmitters as part of our trial.

We have a special thanks to say to our engineering team who took every problem in their stride, delivered a solution and had on us on-air on-schedule for July 1st.

This has also been a very active quarter working with the Broadcasting Authority of Ireland on licencing new services for DAB. The first two of these are All 80s and Raidió Rí-Rá. The latter has been an internet only service up to now and their participation will provide some interesting insight regarding online v’s DAB radio. In the meantime we continue to work with the BAI on three further DAB exclusive services which we hope will be licenced by Q4.

The first three services launched on July 1st were;

Each service broadcasts on traditional DAB and the new world standard DAB+.

Each stations DAB+ service includes Slideshow displaying images as well as the station audio. In particular All 80s are working with All-In-Media’s Rapid software. This delivers rich dynamically updated information from now playing to weather/traffic info plus listener requests all displayed on-screen.

Now the trial is on-air our first task is to slowly bring up the transmitter power and directly compare it with the local RTÉ service. Other tests include variations on actual transmitter, error correction, encoding rates and others.

Each month we intend to post a list of the specific items we are working on and your feedback would be greatly appreciated in the comments section below. Keep up-to-date automatically with these updates by email or RSS feed on our Join In page.

  • Just bought my first dab/dab+ stereo today, I love the clarity obviously but also the extra information, not just the track info but the extra news and comments.

  • Hi,

    Great to have the new additional station on the DAB radio, just one problem is that the audio modulation on Radio RiRa is lower than say All80’s. I have to put the volume up full for RiRa and 7 for the rest.

    regards

    tony.

    • Hi Tony,

      Thanks for the feedback. We’re testing different audio processors on each of the channels which explains why you’re hearing different levels! Good to know that you noticed though.

      Cheers

  • will we ever get DAB reception in County Carlow? thank you. JD.

    • Hi Jonathan,

      Obviously we do hope you’ll get DAB in Carlow .. but it might not be until DAB is rolled out nationally which will be some time yet. However, I was driving on the M9 near Carlow last week and able to receive the DAB Mux from Waterford. Also, a little further north, the RTE Mux was received very clearly.

      Cheers

  • Thanks Dusty,
    I can receive 40,00 stations on my iPhone. Will this kind of advance help or hinder DAB national roll out?
    How many stations will be available? Thanks again, Jonathan.

    • Hi Jonathan,

      Radio via internet on phones/laptops/pads/wifi radios etc is definitely another important avenue for broadcasters and listeners. My feeling is that it won’t become the main avenue for broadcasting for reasons laid out here.

      I’m concentrating on DAB broadcasting because I believe it’s a simpler, more reliable and cost effect method both radio stations AND listeners.

      Regarding the number of stations available on DAB, I feel in the future DAB will bring about 30 brand new radio stations to every home, car and workplace in Ireland.

      Cheers,
      Dusty
