Digital TV explained

Digital TV is a way of transmitting the pictures and sound that make up a TV programme, together with other services like text and interactivity. The information needed to make up the TV programme is 'coded' into a digital stream of ones and noughts – giving a superior image quality. Plus, the digital stream takes up much less capacity in the airwaves, so that the space needed in the past for just one analogue channel can now carry five, six or seven different channels Many of your favourite programmes are in true widescreen on digital channels - something analogue TV cannot display properly.

In addition to the improved picture quality and programme range, you’ll need to decide what you are looking for in a digital TV package:

• finding the cheapest possible deal with a basic channel selection from traditional broadcasters
• being able to pause and record the programme you are watching or another channel
• getting a digital TV in more than one room
• buying a high definition digital TV
• being able to send email via your TV
• getting a deal that includes broadband or home phone
• being able to watch the week’s best shows on demand
• having a greater selection of films
• not being tied in to a contract
• creating a custom made selection of subscription programmes
