Basically it is ran by a huge series of 0's and 1's which is then transmitted into a digital decoder. The decoder then reads the code and the picture is put on the screen. It varies from the analog TV because analogs are a completely different setup. These are ran by radio waves and electromagnetic waves which get decoded into a picture.
American TV went Digital and Play TV is not for Digital TV so it will not work in the USA
You probably won't need to get new televisions, and at worst would need to purchase a digital converter box for roughly fifty dollars.
No, but you can buy small portable digital TVs now.
It would not appear that digital television has changed the world, yet.
No.
Older televisions can make the switch to digital programming with a digital converter. The converters are usually about $20-$60 and are available at most electronics stores.
Yes
No reason why not - digital TV's have a standard aerial connector in addition to one or more SCART sockets.
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.
One possibility: if the signal is a digital broadcast and you have a digital-capable TV but the DVR has an analog tuner, the DVR would not see a recognizable signal, but the digital signal would pass through to the TV.
If you mean a set top digital box, then you can connect that to any tv.... otherwise..... It doesnt work that way. The digital signal is a part of the analog signal. Just screw the cable wire on to the back of your tv.
No, it won't work that way. You will have to buy a new one.
