What does digital TV mean, what is the difference.......??

Question

between that and normal TV, and when the switch over to digital is made does it mean, our TV's now will not work

Answer 1

As far as I know they are going to have boxes to convert analog(your current tv) to digital(new tv signal).
So the answer is yes your current tv will still work, but it will need a converter box.

ps. the picture won't be as clear as the digital tv will be.

Answer 2

When digital TV was first introduced in the U.K., it was touted as being a high quality picture and high quality sound, a great improvement over the analogue broadcast. In truth, picture and sound quality is not a lot better...

So why the switchover? Well, in truth, the Government has bowed to pressure from the broadcasters (Sky, BBC, etc) who want to have more and more channels.
Analogue broadcasts need a lot of 'bandwidth' for their signal - once the bandwidth of that broadcast frequency has been reached, you cannot add any more channels. Digital broadcasts use a very, very narrow bandwidth, meaning you can get hundred (or even thousands, heaven forbid!) of channels into the same broadcast frequency.

In order to watch digital broadcasts on a standard TV, you will need either cable (expensive), satellite (hideously expensive) or a Freeview box (dirt cheap). An old-fashioned TV will work fine with any of those, once the switchover happens, until we finally get all-HD broadcasts in about 2020.

Answer 3

The differences between analogue (or normal) TV and digital is that the quality of digital *should* be better, because interferences do not effect digital (but this is not the case with analogue). Yeah, maybe, but there are problems in that you CAN lose the digital signal easier.

And when the switch is made, analogue TVs won't show anything. So better buy freeview, a digibox, cable, or Sky, pretty soon! (Unless if you can live without the TV...)

Answer 4

Well since the other guys described the lines of resolution to you, I'll give you my opinion on the TV you should get. I really don't think on a 22 inch tv that you'll see a couple of hundred dollar difference between 1080p and 720p. Not only that, but unless you plan on getting a blu-ray player, you'll only be watching 720p content on that TV. And if you do enjoy movies that much where you want to see them in full High Defination 1080P, I would suggest getting a bigger TV so you can actually enjoy the higher quality movie. I hooked a blu-ray player up to a Sharp 32" 1080p TV and I personally didn't think it looked any different than just 720p. I personally think you should just get a higher quality 22 in set (samsung or sony) and then you'll have a great picture with durability. EDIT: Just remember, you get what you pay for, if something is 'cheap', don't be surprised when it is cheap. I would do some serious research on the Vizio brand, I haven't been able to find a true repair rate on them, and from the people I have talked to at Wal-Mart and TV servicemen, they say that are working on Vizio's a lot. Don't look for any repair rates for the Vizio in Consumer Reports, they have yet to put anything in their "unbiased" magazine.

Answer 5

Digital TV signals are transmitted in a series of 1s and 0s in a binary code that only digital TVs or a set top box will be able to decipher..the change over will go in stages across the country starting in 2008 and finishing in 2012
the present signal is transmitted in the same way as radio waves and is being replaced to free up the airways and to give a clarity of picture that should not be affected by atmospherics..

Answer 6

Without getting too technical, more channels can be transmitted at once, but you need a box to decode the signal...so your present TV will need to have some sort of Digital TV box connected...they can be quite cheap now, about £50 for a reasonable one....If you can receive all five channels now, then you will be able to receive digital channels when the change over comes.

Answer 7

There's an ulterior motive to this move, it will free up radio bands that can be sold to such as mobile phone networks. Billions will be made by the government. You'll get loads more channels churning out the same old crap and repeats.

Answer 8

your TV will work, its just you will need to by a digital box, either Freeview, Sky, virgin media, BT and so on and so forth.
but your TV aerial, probly on your roof or in your loft will no longer be needed! good thing is bad weather will no longer affect your reception!

Answer 9

It comes through a satelite,not an ariel, you can get it through a freeview box, or sky

Answer 10

not unless you either have a freeview box, sky or equivalent
