Digital Radio DAB a Difference?

  jack 20:11 10 Mar 2006

You go about life absorbing new terms and technology and make assumptions- then see something in print that raises all sorts of doubts.

As I have read about the merits of Digital broadcasting and digital FM radio and then DAB came along - didn't register particularly
Then I saw and ad for a Digital TV/Radio PCI card
and it seems to differentiate between digital radio and DAB and inferred that it received one but not the other

Are they 2 different things Digital Radio and DAB that is

By digital radio, i think they mean the stations you can receive through a Freeview box / card. DAB radios receive, in addition, stations not included in the Freeview package.

Marketing men playing frantic semantics again; nothing new there.

As far as I am aware, there are basically four ways to receive what could be described as digital audio; internet streaming, digital audio broadcasts at a terrestrial level (from the antennae to the our DAB radios), the similar terrestrial broadcasts that are included in the Freeview system and finally the Sky/Freesat equivalent that comes from satellite to dish.

Taking the second type in isolation, I would not think that a slightly different method of receiving it (PC receiver versus a standalone tuner or hifi) could amount to or require a different source.

A few Christmases ago I bought herself a Roberts Digital Portable Radio. I sounds OK but not outstandingly different to a similar sized FM set.
It is only lately I have noticed the DAB term used.
Yes guess it it is more to do with Marketing than Technology

DAB - Digital Audio Broadcasting is a means of receiving completely interference free radio broadcasts via satellite through a specially designed DAB radio receiver. These are relatively new to market - google for Pure and read the articles there. A few DAB radio stations are receivable on your TV (I use mine for watching pictures) but only a few.
DAB is a totally new way of enjoying radio, speech and music are always crystal clear

Try this for an explanation click here Once you have the digital signal it is all down to what you do with it. Perhaps not a real leap forward with the standard tranny but put it through a good hi-fi system and it will be really noticable.

The Digital TV/Radio PCI card will decode the radio channels provided on the Freeview multiplexes, transmitted on UHF frequencies. The card will require a conventional TV aerial.

DAB radio is transmitted using one or more of the old VHF 405 line ITV frequencies, around 200MHz. For best results this will also require a tuned antenna which will be about half the size of a VHF analogue radio antenna.
