High-definition TV, or HD TV as it is also known, is a new development in digital TV. It offers viewers a better television experience, with clearer sound and pictures. If you’re considering getting a HD TV, or already have one, we’ll help you get the most from it.
Our guide explains exactly what high-definition is, what’s available to watch in HD and which digital TV providers offer high-definition services, as well as looking at all the costs involved.
What is high-definition television?
There are several advantages to getting a high-definition (HD) television. Most noticeably, HD programmes and films have:
- Better picture quality - Images are brighter and clearer. HD programmes have up to five times more detail than ordinary standard definition (SD) TV.
- Better sound quality - Programmes made with surround-sound are better in HD as sound is clearer and sharper.
The sound and picture quality of high-definition broadcasts is around four times better than standard-definition (SD) programmes. HD broadcasts are particularly suited to flat TV screens (LCD and plasma).

What can I watch in high-definition?
If you’ve got a HD TV, or are thinking of getting one, there are plenty of high-definition programmes to choose from on the dedicated HD channels.
A wide variety of programmes, from soaps and documentaries to films and dramas are shown in HD, as well as some sporting events. What you’ll be able to watch in high-definition though will depend on the digital TV service you have.
Several of the larger digital TV providers offer HD channels for customers, but this comes at a cost. Freesat, the free-to-view satellite TV service also offers BBC content in HD, and customers don’t need to pay a monthly subscription.
Below is more information on what is available from the various digital TV services:
- Sky - Satellite TV provider Sky offers the biggest choice of HD channels, including the Sky Sports channels, the Sky Movies channels and Sky1 HD. To get high-definition from Sky you will need a Sky+HD box and a satellite dish. Visit www.sky.com for more information.
- Virgin Media - If you subscribe to a cable TV package from Virgin Media, you’ll be able to watch seven different HD channels, including FX HD, MTVN HD, National Geographic HD, and Living HD. Virgin Media also offers on-demand TV programmes in high-definition. To get HD channels from Virgin Media you need a V+HD set-top box. Visit www.virginmedia.com for more information.
- Freesat - Freesat, the subscription-free satellite TV service, currently offers BBC HD and ITV HD to its users. To get these channels you must make a one-off payment for the Freesat HD set-top box and installation. Visit www.freesat.co.uk for more information.
Freeview has also confirmed it will offer some channels in high-definition later in 2010.
The digital TV providers are adding new HD channels and content all the time, and costs do vary, so it’s important you find a high-definition package that will suit you.
What do I need to receive HD TV?
Before you can watch high-definition programmes, there are four things you must do:
- Get a HD ready TV - If you want to watch programmes in high-definition, you’ll need to make sure your TV is HD-ready - look for the HD ready logo. If you’re considering buying a new set, visit www.hdready.org.uk for more information.
- Get a HD receiver - You will need to get some form of HD receiver. These can be integrated within TVs, such as the Sony Bravia with built-in Freesat, or can be a separate set-top box. Speak to your digital TV provider to see what it offers.
- Get a HDMI cable - If your HD receiver is not integrated in your HD TV, you’ll need a HDMI cable to connect between the two.
- Get a digital TV provider - You will need a digital TV service to provide you with HD content. Use the postcode checker on the Digital UK website to see which providers offer HD services in your area.
Should I get high-definition TV?
If you’re considering getting a HD TV and digital TV service, you need to think about the kinds of programmes you want to watch in high-definition, HD viewers have commented that, most noticeably, nature documentaries and sporting events are better in HD.
Check which providers are available in your area and weigh up the costs before switching to HD TV - if you only watch the news, the soaps and the odd film, at the moment there is not that much content available.
