NO Retard!
A tv antenna and a digital tv and/or a converter box.
You probably won't need to get new televisions, and at worst would need to purchase a digital converter box for roughly fifty dollars.
Very probably yes. If your new TV is High Definition, you will need to get a new HD cable box from Comcast, for which the fee is a little higher.
All Americans need digital TV's because analog TV transmissions have ceased.
Comcast will provide you with a digital tv box that allows your television to receive the digital signal and therefore you won't need the digital tv antenna.
In the US the answer is probably not. Digital and analog TV broadcasts use the same frequencies and antennas. Digital TV is more fussy about signal quality than the older analog signals. So if you get marginal analog reception, figure on getting a new antenna for digital. The idea that there are special HDTV antennas is just marketing hype. Any antenna that gives you better digtial reception will also give you better digital reception.
It does have a digital tuner built in. This LCD TV has a built in digital tuner,so you can receive all digital broadcast.
Digital convertor boxes are meant for those who do not have newer TV sets with digital tuners built-in. The need for these came a few years ago with the digital changeover from the old analog signals. If you have cable or satellite as a provider, you do not need a converter at all. If you are currently using antenna TV and can actually see shows, then you do not need a box, you have a digital tuner already.
i need to tune my tv to digital it is freeview
NO.
no you need a DVD recorder
Yes. Your TV band radio will no longer work. You would need to have a radio with a tuner capable of picking up the new digital TV format. I don't know of any such product currently on the market. Digital radio (marketed under the name HD Radio) is a completely different technology.
