What will happen to analog television frequencies when the stations move to digital?
They will be assigned to other services.
What is analog TV?
Analog television was first used in the 1930s. Analog signals are sent by varying voltage, radio frequencies, and static images.
What are digital converters used for?
Digital converters are used to convert an analog input into a digital current. They also have converters that covert from digital to analog. These are used for older model TVs that need to take a newer digital technology input but the tv still requires analog.
What do you need to do to be able to use your old television and aerial antenna after spring 2009?
If your old tv has no built in ATSC Digital Tuner , then you need a digital to analog converter box. This box receives the ATSC Digital Signal and converts it to NTSC Analog , for Tv's that only have a NTSC Analog tuner.
What happen when we touch the TV antenna?
With analog TV, usually the picture improved slightly, as our whole bodies were being used as an antenna. I don't know if that phenomena holds true with digital signal broadcasting or not.
What are the example of analog devices?
The examples of analog devices are as following: 1. The telautograph 2. Analog synthesizer 3. Analog television 4. Analog Computer
What is analog-TV?
Its a television with an analog tuner built in. It picks up analog signals.
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 come my tv hasn't been workin since febury?
In the United States, broadcasters started broadcasting in the digital format and turning off the old analog transmitters. Many changed channels. Old analog TV can not receive the new digital signals.
What is the difference between ASTC and NSTC digital tv reception?
NSTC is the old analog system of encoding over-the-air television used in the US. ASTC is the new digital system for over-the-air television.
Are HD antenna different from analog antenna?
Not really. While some "HD" antennas are designed to minimize the effects of multipath reflections in large cities, there's no fundamental difference between an "HD antenna" and an "analog antenna". In a larger city where the TV transmitters are nearby and you have a good line-of-sight to them, you'll see no difference. The antenna is only used to pick up the air signal, which is on the same frequency band as old Analog TV. The only difference is the old-style analog NTSC (or PAL or SECAM) TV standard(s) used an analog carrier and the DTV ATSC standard uses a digital carrier. The whole "HD" + "Analog" antenna thing is basically hype.
Can you use old antena with converter box to get HD on your anolog tv?
For most people, their old antenna will work just fine. Don't let the people at the electronics store fool you, there is no such thing as an "HD antenna." There is nothing special that needs to be done to an antenna to receive HD signals. In fact, many of the antennas that are being marketed as "HD antennas" are inferior UHF-only antennas that receive a smaller set of signals than your old antenna. However, some people who were barely receiving an analog signal may need to buy a better antenna. Also, if the location of the digital transmitter has changed or the signal strength of the TV station has changed, you may need to re-aim or replace your old antenna. Simply plug the old antenna into the converter box and then plug the converter box into your old TV where the antenna used to go and you will be fine. The converter box will tune in a digital station (some digital stations are HD, some are not) and convert the digital signal into an old-fashioned analog standard definition signal and feed it into your old analog TV. You will not be able to watch shows in HD on your old analog TV, but you will be able to watch a version of the HD broadcast that has been converted into Standard Definition (SD) for you. You will be able to watch all of the digital stations including the HD ones but you will see them in Standard Definition. Standard Definition is 480i. Digital to Analog converter boxes receive all tv transmissions of 1080P , 1080i , 720P , 480P , 480i and coverts them ALL to 480i to watch on a standard definition NTSC Analog TV.
