Our TV and Tech podcast regularly features Digital TV - here's a summary of the digital options in the UK

What is Digital TV?

Digital offers more TV choice, less interference, and improved features, but what are the options?

The UK is slowly switching to digital TV, and the UK is set to switch everyone over to digital by 2012. Over the next few years, you'll need to be ready for digital TV.

What are the options?

In the UK, there are several main ways to get into the world of digital TV:

Sky Digital	The UK's digital satellite provider is Sky Digital. To get Sky, you need to sign up, then have one of Sky's engineers to install a satellite dish to your house and to connect a 'digibox' - a set-top box that into your TV. You'll also need to plug the box into your phone line, as a condition of subscribing. What's on offer: With Sky, you get the largest range of channels around. Some channels are free to watch, but most require a Sky Digital subscription, which is paid monthly. Offers: Prices start from £18 a month when you order online. You can also get special packages combining TV, Broadband and phone - free Sky digibox, Broadband Internet and free UK evening and weekend landline calls. Extras: Other extras include the Sky+ disk recorder, and a Sky+ HD High Definition set-top box Summary: Largest channel lineup. Needs a dish. Pricey subscription More info on our Sky Digital page. To explore the options, go to www.sky.com.
Freeview	Freeview is, as the name suggests, a free digital TV service. It uses your existing TV aerial to get its signals. All channels are free to watch, there's no installation or subscription cost and no engineer needs to visit (assuming you have a good enough aerial). What's on offer: Freeview offers around 60 channels of digital TV and radio - considerably less than Sky, but enough for many. Channels include BBC3, ITV3, ITV4, E4, BBC News, Dave, Virgin 1, History, Sky 3, Film Four and More4. To get Freeview, you need to check that you're in a Freeview coverage area, then buy a Freeview set-top box. These are available for upwards of £25 from Dixons, Comet and Argos. Summary: No subscription. Cheap startup cost (from £25). Small number of channels More on our Freeview page
Cable	If you're served by cable TV operator Virgin Media (formerly Telewest and NTL), they may be able to provide you with a cable TV package, as well as phone services. Again, you'll need a set-top box to receive services, and you'll need a visit from an engineer to connect you. What's on offer: A good selection of TV channels, and access to a large collection of on-demand movies and TV shows.. To see if cable TV is available in your area, go to www.virginmedia.com Summary: Must be in Cable TV area.

Get BBC, ITV, channel 4 and Five catch-up TV.

Recording Digital TV

When you've selected which Digital TV service you're happy with, you'll probably want to know how to record TV shows. There are a number of ways. Here's a quick summary, and some pointers:

PVR: Also known as a DVR, this is a digital TV set-top box that has a built-in hard disc recorder. The Sky+ box is probably the best known PVR. It supports recording of over 40 hours of TV, supports series link, allows you to record one channel while watching another, and supports live pause. PVRs are available for Sky, Virgin Media and Freeview. BT Vision offers a free PVR if you're a BT Broadband customer. More details on digital recorders: DVRs Explored
DVD: With videotape being phased out, recording and archiving onto DVD is a logical progression. Stand-alone DVD recorders are reasonably priced, and can connect to an existing digital TV set-top box via a SCART lead. Some of them come with a built-in Freeview receiver, which means you should be able to record one Freeview channel whilst watching a different channel on your main receiver. More details on DVD recorders: DVD Recorders explored
Computer: For many, recording TV onto a computer is the preferred choice. TV receiver cards for PCs are cheap, and most PCs have a decent amount of storage for video content. A Freeview TV card with recording software for a PC shouldn't set you back more than about £50, so it's worth considering. More info: TV on a PC ; Archiving your video
Video tape: Good old VHS cassettes. Assuming your video cassette recorder has a SCART socket, you should be able to connect the output of your Digital TV set-top box to a spare SCART input on your video recorder. Then, you'll need to set the video recorder to record from the 'Line in' channel, and you should be able to record. One down side is that you can only record whatever channel the set-top box is tuned in to. For greater flexibility, you might want to consider a second digital TV receiver, or a PVR.
