Digital TV
Most people now have some form of digital TV in their home, whether it's satellite based via Sky TV, or cable from the likes of NTL / Virgin Media. Thankfully, with the development of Freeview you can now tune into more than just the terrestrial channels while you are away from your house, in a motor home or caravan with 12v DVB boxes.
You can also get DVB systems with twin tuners giving you enough power to receive digital TV while on the move. Enjoy access to the likes of E4, More4, Film4, ITV2 and ITV3, BBC News 24 and various Sky channels to name but a few.
