How does it work?
DAB radio works by using both MPEG and COFDM (Coded Orthogonal Frequency Division Multiplex) technology which converts the music or speech from analogue signal into digital (binary) code
How is this different from FM?
The sort of interference which commonly disturbs FM reception (caused by radio signals bouncing off buildings and hills) is eliminated within DAB signals. DAB technology is able to filter out interference and correct signal errors.

What is digital radio?
Digital radio offers many benefits to its listeners.
The main benefits are:
-
More radio stations: catering for all kinds of interests and groups of people
-
Better reception: none of the hiss, crackle, fading or station overlap that you get with AM or even FM radio
-
Easy tuning by pressing a button: no need to remember frequencies, fiddle with a dial to get a good signal, or retune your car radio when on the move
-
Display screen on the radio: gives you information about what you're listening to (such as song details, news headlines, email addresses); some radios now have an electronic programme guide (EPG)
-
Radio on TV and online: digital radio stations also broadcast via digital TV and on the internet
How do I get digital radio?
You can't receive digital radio on a traditional (analogue) set. There are three ways to listen:
-
DAB digital radio set: as with traditional sets, there are many kinds to choose from – portable, hand-held, hi-fi tuners, car radios, etc. Please check that you can receive digital radio in your area by entering your postcode at Get Digital Radio. The BBC digital radio services are available to 87% of the UK population and will reach 90% by early 2010.
-
Digital TV: all digital TV platforms (digital terrestrial, satellite, cable, broadband) include at least 20 radio stations.
-
Internet: with speakers or headphones plugged into your computer, you can listen to a huge variety of stations from the UK and all over the world. You can also listen to all the BBC radio stations on an internet radio.

Strike warning over BBC plans 'to cut services'
Union leaders have warned of industrial action after reports that the BBC is planning to close two national radio stations and scale back its website.
The broadcasting union Bectu and the National Union of Journalists (NUJ) accused the BBC of bowing to pressure from politicians and commercial rivals.
According to the reports, BBC Asian Network and 6 Music will be axed as part of the cost-cutting proposals.
The corporation said details of the strategy review had yet to be agreed.
Leaders of Bectu and the NUJ said they met a BBC director on Friday and were told the reports in the Times newspaper were "largely correct".
They expect to meet the BBC's director general Mark Thompson next week.
'Political climate'
In addition to the reported closure of BBC Asian Network and 6 Music, the BBC is to reduce the number of its web pages by half and cut online staff by a quarter, the reports said.
The moves, according to the Times, are part of a strategic review which places quality ahead of quantity. Imported TV shows and sport are also set to be cut.

These cuts will result not just in the loss of hundreds of jobs, but the loss of valuable, quality output aimed at young people and the Asian communities
Jeremy Dear, NUJ
| The proposals would reportedly yield savings of £600m, which could be redirected to higher quality programming.
Some commentators have said the BBC's plans were an appeasement to an anticipated Conservative government that believes the BBC should be cut down to size.
Gerry Morrissey, Bectu's general secretary, said the union would oppose the closures and claimed the BBC was "being bounced by its competitors and by the political climate ahead of the upcoming general election".
NUJ general secretary Jeremy Dear said the union would "fight the cuts with all its might".
"If true, these cuts will result not just in the loss of hundreds of jobs, but the loss of valuable, quality output aimed at young people and the Asian communities," he said.
"We will do everything that's required, including taking industrial action, if necessary, to defend jobs at the BBC."
'Cultural vandalism'
The BBC said speculation was premature and the proposals would be presented to the BBC Trust in the near future. If approved, they are then expected to be put out for public consultation.
Despite the lack of confirmation over the fate of the digital radio stations, their supporters have spoken out against the leaked proposals.
Phill Jupitus, who was the first breakfast show host on the station, writes in Saturday's Guardian: "Cutting 6 Music is an act of cultural vandalism, and an affront to the memory of John Peel."
Sunny Hundal, editor of Asians in Media magazine, told BBC 5 live that cutting the Asian Network would deprive listeners of a valuable place where Asian content was integrated with mainstream output.
"There are a lot of people in Britain who produce hybrid British-Asian music and culture and they want to see some of that culture on display," he said.
David Elstein, former chief executive of Channel 5, said the corporation would face greater pressure after the general election, which is expected in May.
"I tend to regard this as trying to look smaller without ever actually being smaller," he told BBC Radio 4. "The BBC's income isn't actually going to go down.
"The bigger issue by far is that the BBC's income continues to rise every year. So the key issue that its critics have raised - which is the sheer size of the BBC - has not been addressed and I suspect that that will be addressed for the first time seriously after the election."

TV's future in the hands of viewers
With home theatre systems, plasma high-definition TVs, and digital video recorders moving into the living room, the way people watch TV will be radically different in five years' time.
That is according to an expert panel which gathered at the annual Consumer Electronics Show in Las Vegas to discuss how these new technologies will impact one of our favourite pastimes. With the US leading the trend, programmes and other content will be delivered to viewers via home networks, through cable, satellite, telecoms companies, and broadband service providers to front rooms and portable devices.
A la carte fears
One of the most talked-about technologies of CES has been digital and personal video recorders (DVR and PVR). These set-top boxes, like the US's TiVo and the UK's Sky+ system, allow people to record, store, play, pause and forward wind TV programmes when they want.
Digital video recorders like Sky+ give scheduling control to viewers
| Essentially, the technology allows for much more personalised TV.
They are also being built-in to high-definition TV sets, which are big business in Japan and the US, but slower to take off in Europe because of the lack of high-definition programming.
Not only can people forward wind through adverts, they can also forget about abiding by network and channel schedules, putting together their own a-la-carte entertainment.
But some US networks and cable and satellite companies are worried about what it means for them in terms of advertising revenues as well as "brand identity" and viewer loyalty to channels. Although the US leads in this technology at the moment, it is also a concern that is being raised in Europe, particularly with the growing uptake of services like Sky+.
"What happens here today, we will see in nine months to a years' time in the UK," Adam Hume, the BBC Broadcast's futurologist told the BBC News website. For the likes of the BBC, there are no issues of lost advertising revenue yet. It is a more pressing issue at the moment for commercial UK broadcasters, but brand loyalty is important for everyone.
"We will be talking more about content brands rather than network brands," said Tim Hanlon, from brand communications firm Starcom MediaVest.
"The reality is that with broadband connections, anybody can be the producer of content."
He added: "The challenge now is that it is hard to promote a programme with so much choice."
Content
What this means, said Stacey Jolna, senior vice president of TV Guide TV group, is that the way people find the content they want to watch has to be simplified for TV viewers.
It means that networks, in US terms, or channels could take a leaf out of Google's book and be the search engine of the future, instead of the scheduler to help people find what they want to watch.
This kind of channel model might work for the younger iPod generation which is used to taking control of their gadgets and what they play on them.
But it might not suit everyone, the panel recognised. Older generations are more comfortable with familiar schedules and channel brands because they know what they are getting. They perhaps do not want so much of the choice put into their hands, Mr Hanlon suggested.
"On the other end, you have the kids just out of diapers who are pushing buttons already - everything is possible and available to them," said Mr Hanlon. "Ultimately, the consumer will tell the market they want."
TVs galore
The warning of square eyes is forgotten at CES
| Of the 50,000 new gadgets and technologies being showcased at CES, many of them are about enhancing the TV-watching experience.
High-definition TV sets are everywhere and many new models of LCD (Liquid Crystal Display) TVs have been launched with DVR capability built into them, instead of being external boxes.
One such example launched at the show is Humax's 26-inch LCD TV with an 80-hour TiVo DVR and DVD recorder.
One of the US's biggest satellite TV companies, DirectTV, has even launched its own branded DVR at the show with 100-hours of recording capability, instant replay, and a search function. The set can pause and rewind TV for up to 90 hours.
And Microsoft chief Bill Gates announced in his pre-show keynote speech a partnership with TiVo, called TiVoToGo, which means people can play recorded programmes on Windows PCs and mobile devices. All these reflect the increasing trend of freeing up multimedia so that people can watch what they want, when they want.

Digital TV project to be extended across Wales
A trial project to enable people to use digital TV to connect with their local council will be extended across Wales.
The Digi TV project allows people to access local authority information and services via set top boxes using remote controls.
The project has been successfully trialled in the five heads of the valleys authorities and in Wrexham.
The all-Wales trial is set to last a year and should be fully evaluated by April 2011.
Social Justice Minister Carl Sargeant announced the extension of the trial on a visit to Wrexham council's point of access for information and services, Contact Wrexham.

Digitally excluded people who don't have access to the internet at home will now be able to access services similar to those available on the web
Social Justice Minister Carl Sargeant
| Mr Sargeant said: "I am particularly pleased that this system will be available to the vast majority of Welsh homes once the digital switchover has taken place as any home with a digital television signal should be able to access the services.
"This means that digitally excluded people who don't have access to the internet at home will now be able to access services similar to those available on the web.
"This project has a great deal of potential and if successful, could be extended to other public services such as health services."
Mr Sergeant said public services faced unprecedented pressures and would have to do things differently to ensure value for money.
He described Digi TV as an excellent example of innovative ways of working which allow people to engage with service providers more efficiently and councils to plan their services appropriately.

Digital switchover causes TV problems in Oxfordshire
An apology has been given to viewers in Oxfordshire who have been experiencing problems with their TV reception.
Digital UK said it was carrying out maintenance on the television mast at Beckley in preparation for digital switchover, due in 2011.
The BBC has received many enquiries from viewers, some who have bought new equipment after suffering signal loss.
Digital UK said the work was essential, and hoped it would be complete by the beginning of April.
Channels worst affected include ITV 1 and 2, Channel 4, E4 and five.
'Short-term work'
Some viewers have complained that they were not told about the transmitter work.
Philip Brogden spent more than £100 trying to fix reception problems.
He said: "They should have informed us in the first place. Otherwise I would not have spent a whole load of money on pieces to make my TV work."
A reserve aerial has been fitted half way down the Beckley mast so that the old aerial can be lifted off by helicopter.
Peter Monteith, from Digital UK, said: "This is relatively short-term work and we will be finished, weather permitting, by the beginning of April.
"We do not underestimate in any way how irritating this is, and we do apologise."
