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. 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.
Yes
No reason why not - digital TV's have a standard aerial connector in addition to one or more SCART sockets.
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.
Whether your television will work well for PC gaming depends on a number of factors. The television would need to have the same type of connector that your computer uses. If they both have VGA, Display Port, HDMI, or whatever, then it should work.Then the connectors would need to have the same standards. Some connectors carry both analog and digital signals, and if one is digital only and the other analog only, or there is a pin blocker in the plug or socket that causes an otherwise appropriate combination to not fit, then it won't work.
