Television has undergone huge changes since we first started getting black and white broadcasts back in the 1930s. Screen sizes have grown, pictures are now in colour and we even have the visual delights of HD, all presented to us on more channels that we've ever had before.

The old analogue signal has been working hard since TV began, but it's starting to show its age and can't cope with the demands of today's technology. That's why it's being turned off.

Many areas of the UK have already made the switch to a digital signal, but changes are still being made to update the airwaves for 4G. Our guide will tell you everything you need to know.

The Knowhow

Why is the switchover happening?

The analogue system can't cope with the level of detail or number of channels available today. The new digital signal is much stronger, meaning you'll get better reception, picture and sound. You'll also be able to watch high definition programs and select from a whole range of new channels.

IMPORTANT: You will need to ensure every TV in your house is converted and ready for the digital signal. Almost any television can be converted so it isn't necessary to buy a new one. However if you do decide to buy a new TV, make sure it carries the 'digital tick' logo. This means it will continue to work after the switchover.

When is the switchover happening?

Most regions have already been converted to a digital signal. There will still be a need to retune again for some users, as the introduction of the 4G signal is changing our airwaves once more.

How can you make sure you're ready for Digital TV?

Televisions:

All new TVs now include a built-in digital tuner to provide access to digital programmes from services such as Freeview or Freesat, but if you have an older model you may need to invest in a digital box so they can display the picture. You can also receive digital TV through satellite and cable boxes from paid services, such as Sky or Virgin.

If you decide to use a separate set-top box, you will need to choose one with a SCART or RF adapter depending on the type of connections your television has.

SCART sockets are long and almost rectangular, as pictured above. There will be at least one of these on most modern televisions.

RF sockets are small and round. This is the same socket you would normally plug an aerial cable into.

Retuning existing set-top boxes or services such as Freeview:

If you've not already done so, you will need to retune your service to receive the digital signal.

You will need to perform a full re-tune or factory reset, rather than just updating the channels. To update, your device needs to remove all the old channels from memory, then detect them on the digital signal and add all the new ones. The process takes a few minutes and your device might restart a couple of times during it.

Exact methods for performing this action will vary according to the equipment you are using. The instruction manual should give you more information. If you have any problems, or find you have missing channels after the update, contact your device's customer support.

Digital Switchover Help Scheme:

The BBC is running a help scheme to help switch one of their TVs to digital.

This scheme offers new equipment, installation and aerial adjustment, among other things.

This help is available to those aged 75 or older as well as many disabled people. Those who are eligible will be contacted automatically several months before the switchover date.
