Digital TV had revolutionised the way we watch TV. Not only does digital TV provide superior picture quality, better sound quality and a wider range of channels, it also has the advantage of interaction.
TV viewers can access further interactive content such as catch up TV and programme guides.
There are many ways of watching digital TV and our handy guide looks at the main options and their pros and cons.
Seven tips for using BBC iPlayer
Traditional TV broadcasts received via a home TV aerial are still the most common way to view live television.
Using services, such as Freeview, you can get over 60 TV channels – including more than 10 high-definition (HD) channels.
• All modern HD TVs include a Freeview tuner or you can buy a Freeview set-top box for under £30.
• Once connected to your TV aerial and television set, you can view live TV in crystal-clear digital quality.
• With no monthly subscription, it’s one of the cheapest ways to watch TV.
• Signal coverage for Freeview isn’t 100% – some areas of the UK have patchy coverage or not the full number of channels.
• While 60 seems like a lot of channels, it’s less than some of the other TV services.
Satellite TV services use a satellite dish attached to your home to receive television broadcasts.
One of the most popular satellite TV providers, Sky charges a monthly fee.
The Freesat TV service offers Freeview TV using a satellite dish for a one-off cost of buying a Freesat receiver.
Satellite TV advantages:
• Services from Sky can be expensive, but you’ll get a huge range of channels – many in HD – as well as exclusive Sky channels such as Sky Atlantic for viewing popular TV shows such as Game Of Thrones.
• Install a dish, and you’re likely to get great coverage wherever you live. You can even opt for the subscription-free Freesat service that delivers more channels than Freeview (200 vs 60) and on-demand services, such as BBC iPlayer.
Satellite TV disadvantages:
• You’ll need to install a satellite dish, which can be difficult on rented homes or flats.
• For the widest choice of channels, you’ll need to sign up with Sky, which can be pricey depending on the TV package.
• Some atmospheric conditions can degrade the TV signal, but this is rare.
Ten things your Sky remote control can do
With cable TV, the television signal is delivered via fibre optic cables in the ground, which result in great picture quality and a reliable service.
Cable services are offered by Virgin Media and BT, and you’ll need to have the service installed at your home before you can use it.
Cable TV advantages:
• Fibre optic cable’s ability to handle lots of channels means lots of choice. Virgin Media offers the widest-range of TV channels – nearly 240 channels and 43 HD channels – covering movies, sport and entertainment.
• Cable also excels at on-demand TV, so you can watch movies, documentaries and TV boxsets whenever you choose.
Cable TV disadvantages:
• Only around 50% of UK homes can get cable, although some specialist cable companies serve uncabled areas including WightFibre in the Isle of Wight.
• If you opt for cable, you’ll need to sign a contract for 12 months with the cable TV provider.
• Cable TV also lacks a handful of exclusive channels found on satellite TV.
A fourth way to watch TV is emerging. By using a computer or tablet, you can watch TV over your home broadband.
All you need is a fast broadband service (8Mbps and higher) and a modern tablet, smartphone, smart TV or computer.
What is superfast broadband?
Internet TV advantages:
• Most internet TV services, such as BBC iPlayer or All4, are a mix of catch up TV with some live broadcasts, and are subscription free.
• Access to the main channels, such as BBC, ITV and Channel 4 are via dedicated websites or apps, and usually allow the previous 30 days of TV to be viewed, as well as live broadcasts.
Internet TV disadvantages:
• You’ll need fast broadband, and watching TV on a computer isn’t the same as viewing on a large HD TV.
• Most services are geared to serving catch up TV, and changing channels can mean having to launch and navigate through different apps.
• If your broadband has lots of traffic – such as other family members using it – the TV stream can stutter or stop.
