Digital TV explained
If you're looking for a wider channel choice than the five standard UK channels available, then consider moving to Digital TV.
The common assumption is that this involves getting a satellite dish and a subscription to Sky. Certainly, Sky is a great proposition for those looking for the widest range of channels, but there are alternatives, including the subscription-free Freeview service.
If you're confused about your options, this page may help.
What are the bonuses of digital TV?
Digital TV brings more channel choice, in better quality than the five standard analogue TV channels, and with some nice extra features & services:
More channels - Sky offers the biggest channel line-up, but check your potential provider to see if they have what you're after. Popular channels include Sky One, E4, BBC3, Virgin 1 and UKTV Gold. Channels exist for comedy, Sci-Fi, music, movies, news and sport.- EPG - An electronic programme guide. Much better than Teletext for seeing what's on.
- Better quality - Nice sharp pictures, without the ghosting and interference seen on normal TV. High definition is available on some digital TV services.
- Pay-per-view services - Pick from a selection of movies, special sporting events, or adult programming and pay via your subscription or credit card.
- Improved viewing - with services like widescreen, Dolby 5.1 surround sound, and interactive services.
- Digital recording - Record digitally onto hard-disk, or record a digital channel whilst watching an analogue show. Boxes called PVRs (Personal Video Recorders) make recording and managing digital channels a breeze - Services like Sky+ give you greater control of what you record.
What are the options?
The options open to you if you want digital tv in your home are:
| Satellite | See Radio & Telly's Sky page for details. You'll also find information on Sky in the regular FrequencyCast podcasts
|
| TV aerial |  Freeview. This is known as Digital Terrestrial TV (DTT) and is received through your standard TV aerial. Freeview launched in October 2002, as the successor to onDigital/itvDigital. Freeview offers around 60 channels of digital TV and radio - All channels are free to watch, and no engineer needs to visit (although an aerial upgrade may be needed if your current aerial isn't suitable). Channel line-up is more limited than Sky Digital.  You can get Freeview for a one-off payment of around £30 (to buy a set-top box), provided you're within a coverage area (check coverage). Channels available on Freeview include BBC 3, BBC 4, E4, ITV2, Dave, BBC News, Virgin 1, Cbeebies and UK History.With Freeview, there are a couple of options to consider - subscription to extra channels with Top Up TV, and TV content over Broadband with BT Vision.

| Cable TV | If you're served by cable operator Virgin Media (formerly NTL / Telewest), they may be able to provide you with a cable TV package, as well as phone services. Again, you'll need an engineer to visit to get you connected and to provide you with a set-top box. |

What is Sky+?
Sky
Plus offers a better experience for Sky customers. You get a more powerful set-top
box, which allows
you to watch one satellite channel while recording another satellite channel,
record programmes without videotape (onto the built-in harddisk), set up Series Link, and pause
live TV (for when the phone rings).
Exceptionally versatile, and highly recommended! Click

What's right for me?
For the widest channel line-up, it has to be Sky, but a dish may not be suitable for you. If you're looking for a good collection of extra channels without paying a monthly subscription, then we'd recommend Freeview.
