What uses a digital signal?
Many television stations have been using digital signals for at least 30 years. They turned them into analog signals at the antenna for broadcast. Now they are simply leaving them in their original form.
How do you know if your TV is digital or analog?
"Standard-definition" (meaning 480i) Cathode-ray tube televisions are analog. CRT TV's are easily identifiable by their immense weight and the fact that their depth nearly matches their width and height. Newer, hi-def (720p, 1080i/p) televisions are almost all either lcd, plasma, or dlp, all of which are digital. for digital TV monitor shouldnot be of CRT.
Will the digital TV signal cause damage to an analog TV that does not have a digital converter box?
No.
Will you still be able to use your non digital television once the switch over?
Yes you will. The digital switch over that is progressing in many countries is supported by the promotion of digital set top boxes. They are available at a minimal cost ($25 in the US or £20 in the UK for example). The set top box receives the digital transmissions and converts the signal to analog video and audio signals to be fed into an analog television. With a very few exceptions, analog televisions will not handle HD channels but they should be quite capable of receiving all SD channels. Similarly, most satellite and cable boxes have SD analog outputs so analog televisions will work with most broadcast platforms.
Is HD broadcast the same as digital broadcast?
All HD broadcasts are digital. Not all digital broadcasts are HD. "Digital" is simply a way of coding TV pictures onto a radio wave so that your TV can receive the radio wave and turn it back into a TV picture. The old method was called "analog." Digital is more efficient than analog and allows a lot more information to be carried on the radio wave. Since the wave can now carry more information, some TV stations are choosing to use that extra information for a high definition (HD) picture rather than a standard definition (SD) picture. In fact, there is so much extra room with a digital signal that most TV stations can now show several different programs at once! Most channels will now have several sub-channels. For example, instead of having just Channel 7, you might have Channel 7.1, 7.2, 7.3, and so on -- each with a different program. An HD signal takes up a lot of room, so TV stations that broadcast an HD signal have less room to add additional sub-channels. What is happening with the digital transition is that all analog TV broadcasts will be turned off. Only digital broadcasts will remain on the air. Each TV station decides what it will do with its digital signal. It can use the digital signal to broadcast one HD sub-channel and a few SD sub-channels or it can broadcast a lot of digital SD sub-channels. Most TV stations will choose to broadcast at least one HD sub-channel.
Will there be over the air digital TV broadcast after February 2009?
Yes. That what they are switching to. There will no longer be analog broadcast.
What advantage do digital television signals provide over analog signals?
Digital signals produce a higher quality picture and many programs can be broadcast on a single digital channel, whereas only one program can be broadcast on an analog channel
What is digital analog?
Analog TV:Analog (or analogue) television encodes television picture and sound information and transmits it as an analog signal: one in which the message conveyed by the broadcast signal is a function of deliberate variations in the amplitude and/or frequency of the signal. All systems preceding digital television, such as NTSC, PAL or SECAM are analog television systems. Digital TV:Digital television (DTV) is the sending and receiving of moving images and sound by discrete (digital) signals, in contrast to the analog signals used by analog TV.
How are digital images transmitted?
Digital images are transmitted on computer networks by first compressing them to reduce their size. JPEGs are an example of compressed image files.
What are the advantages of digital data compared to analog data?
Digital data requires less bandwidth than analog data (e.g. new digital television broadcast compared to old analog broadcast), so more data can fit in the same frequency (e.g. DSL compared to analog modems). This is the primary advantage, although it is also generally stated that data is easier to recover and more tolerant towards interference.
Will satellite TV be all HD in February 2009?
No. All satellite TV is digital now. Some satellite TV is HD now, and more will be switching from HD to "standard" resolution. The February 2009 analog-to-digital switchover in the United States has nothing to do with HD. The digital conversion changes the format of the over-the-air broadcast channels from analog to all digital. But if you have satellite or cable TV, you don't get "broadcast" signals anyway.
Will a Canadian TV work on the power in France?
No. Canadian current is 115 volts 60 cycles, French is 230 volts 50 cycles. Also, Canadian televisions expect a NTSC analog signal or ATSC digital signal. France uses SECAM analog and DVB digital signals. So even if you could get power for the set, it wouldn't be able to view any French television signals.
How can you convert the digital to analog or analog to digital?
Buy a new digital ready tv, get a digital receiver Sky or Freeview for your analogue tv
If I buy a vcr with a tuner will it work as a digital converter box for broadcast tv?
The Magnavox Digital DTV Converter Box with Analog Pass-Through will allow you to digitally convert and still use your VCR.

Will a wii work on a analog tv after the digital switch over?
Yes it will. The digital switch over relates to broadcast television only. Analog broadcasts are being turned off from 2009 - 2012 across several countries. Local sources such as DVD players and games consoles will not be affected in any way at all.
Is GE TV Model 27GT617 analog or digital?
27" Analog.
