[cma-l] Local Digital Radio

[Ian Hickling]

In technical terms it's very simple.
All it needs is one B III channel group to be cleared - not necessarily the same one nationally but one that isn't currently occupied in each discreet location - and a transmission system installed the same way as with Community Radio.
The only slightly unusual port of the chain is the digital encryption module - otherwise the RF or digital STL, the transmitter, cable, antenna and structure are all effectively off-the-shelf.
We could put one together now in about 6 weeks if the licensing were available - which it's not.
But the big obstacle here is - which encoding system are we going to use?
DAB (= Deadend Audio Broadcasting) - or one of the many others?

I was just about to email this around.. its a fantastic idea and something I have been talking about for a while.. as other countries have a different approach to dab coverage..


Surely using a similar method to local TV (isnt it graphical inter-levered space?) or a dedicated channel, we could have local DAB coverage for community stations (either as a dual transmission or DAB only stations), however this would depend on the technical / carriage implications, eg we would ideally like to deal with our own transmission and carriage and not have to be forced to use another provider.. 


Question for Jaqui / Bill, is the sort of thing we can get on the agenda as part of the communications bill stuff next year?

Excerpt:

Next, “DAB in a box” – not a coffin, but a few different low-cost
boxes, shown off by Mathias Coinchon and Stanislas Roehrich from the
EBU. The issue with DAB is lots of broadcasters think it’s really
expensive to broadcast: but it needn’t be. Using open software from
the CRC in Canada and some low-cost transmission kit, a DAB multiplex
was magically set up in front of us – including one channel called
“James’s cat purr”, a channel that just had the (royalty-free) sound
of a purring cat. A very impressive demonstration, and one that should
perhaps give Ofcom pause for thought: what would happen if two DAB
frequencies were simply given to community radio services up and down
the country, to run low-power DAB multiplexes themselves? What amazing
additional choice we’d have then!
