Some folks still aren't digitised and dont know where to start. So... another one to play with.

There are several ways to receive digital TV. This is an introduction to the options, which are covered in more depth in other articles.
==Digital TV== New TVs often incorporate a digital tuner. These receive digital from an existing house TV aerial, if the quality of the signal's good enough. Digital requires much better signal quality than analogue.
==Set top box== A set top box connects between the roof aerial and the TV. It converts the digital signal from the aerial to analogue for the TV. The box is connected to the tv by either a scart lead or co-ax, scart giving slightly better quality. Some converter boxes only have scart output. Set top boxes need a better signal than analogue TV, and perform best with CAI approved co-ax wiring rather than old tv co-ax.
==Cable== Cable TV is provided by various companies around the country. The cable co installs the digital box, and this connects to your tv the same way as a set top box. No roof aerial is needed.
==Satellite== You need a satellite dish, satellite receiver, and a subscription for the satellite service. Note that satellite frequency signals can only be fed down the best quality co-ax, decades old tv co-ax is no use.
==Internet== The final and rather limited TV source is the internet. You won't get the main TV channels on the net though. What's available:
- BBC iplayer: plays a selection of the most popular programs on demand, up to 30 days after airing.
- Various video viewing sites, eg youtube, google, etc
- Masses of instructional videos on numerous sites, covering pretty much any subject you can think of.
To watch much tv over the internet on your computer takes a lot of bandwidth, a low download limit account won't do.
