If the tv signal is coming to your house by a tv antenna on the roof, then a special very wide band radio signal is used. Your classic tv tuner can pick one tv channel out of all the different channels that are in the air. Same idea is used for satellite dishes except the signal has been converted to be a very high microwave frequency, and you need a satellite receiver to convert the microwve signals back to regular tv tuner signals.
If you have cable tv, the similar tv signals come to your house, only they get to your tv through a wire and there is no antenna used.
The signal for a single channel is about 4-5 megahertz wide. That's like an FM radio station channel that goes all the way from 100 to 105 on the FM dial, for a single channel. You could only squeeze 3 or 4 channels in to whole FM radio band.
The tv pictures are sent one at a time, about 30 per second, so it looks like smooth motion.
To visualize the structure of a tv signal: At about 100 mhz would be special pulses and codes to start the picture. From 100.5 to 104.5 would be the thousand of color dots you see on the picture tube, and the briteness of each dot. Then at 104.5 you would find the soundtrack which very much like an FM radio station, infact you can listen to the audio without watching the picture, on some radios.
Every second many slightly different pictures are flashed before your eyes on the screens and all you see is the smooth tv motion pictures.
Hope this helps a little.
Picture is AM, sound is AM or FM
The signal sent to the TV must be a digital signal as well.
Originally the television was sent in the form of a type of side band transmission. The picture was sent on half of the signal and the audio was sent on the other side of the signal. We do not have room to go into the theory of sideband transmission here. Anyhow Since the two parts are sent in a way analogous to a car pulling a small trailer, it is as if electronic devices unhooked the trailer. Picture the video part as the car and the sound as the little trailer. The video goes to the monitor and the sound to the speakers.
If you sent the picture from your phone it first needs to be on your phone to begin with. So all you need to do is either:1. Go to your sent folder and look there for that picture mail you sent.or2. Go to your pictures section/folder and look for that picture that you sent.if your talking about what that message would look like after you sent it, then either:1. Look at that persons phone you sent it to for your picture mail.or2. Try your sent folder again.

if you are asking about the live television footage, the signal was sent via radio waves from an antenna on the LM and received by the Parkes radio telescope in Australia. If you are asking about the still pictures, they were brough home by the astronauts and developed on site at NASA.
The TV format setting is so that it sends the correct picture information when connected to a TV. It may be connected to a 4:3 aspect ratio TV or a 16:9 aspect ratio TV. For example if it was sending a 16:9 picture to a 4:3 TV, some of the picture to the left ad right sides would be missing. If sending 4:3 picture to a 16:9 TV the picture would be stretched across the screen distorting the picture.
CRT TVs are different from LCD TVs in the way the picture is build up on the screen. Electrons are being released with highspeed in CRT TVs to build up the picture while in LCD TVs liquid crystals make up the picture.
yes. Rauschenberg's picture painting appeared in Fraser's hallway at the back of the set where his room is supposed to be. I have an exact replica of this at home.
