up to the time the signal from the station reaches your TV both the picture and sound are transmitted in the same format, so they arrive at the same time. The TV then divides the signal and sends the electrical impulses to the different components of the TV, which arrive at the same time.

The picture and sound are output from the TV at the same time, and travel a very short distance to your eyes and ears where they are interpreted. The distance is so short that your brain thinks they happen at the same time, even though they don't. This is because the difference in travel time between the light and sound is so small as to be unnoticable, even if your listening for it.

The Picture signal and the sound signal both leave the transmitter riding on ( modulated ) a radio frequency which becomes your Chanel number . They therefore arrive at your tv at the same time, the picture info is removed and sent to the pic tube and the sound is removed and sent to the speaker, the tv set demodulates the signals then that the transmitter has modulated. Note this is a very simplistic explanation. Cheers Pete

The speed of light is approximately 186,282.397 miles per second.
The speed of sound is approximately 770 miles per hour.

If you're only 10 feet from your T.V., it only takes 0.0088 seconds for the sound to reach you. At this speed, your brain simply isn't capable of discerning any difference at all. It's much like movies: unlike the real world it's a collection of frames being displayed so fast your brain can't keep up, creating the illusion of movement.

It should be noted that people several miles from massive explosions see the blast well before the soundwaves reach them.

If you were far enough away from the tv and you could still see the picture, the voices/sound would be off. But because you are only 6 feet away on average from a tv, you wont ever hear the difference.

The sound and sight from a flash of lightening and the subsequent thunder, can be far apart from each other because of the often many miles of distance between you and the bolt of lightening.

Well first.....you're wondering how the picture and sound are synced when transmitted, am I right???

BOTH Picture and Sound are transmitted to your TV USING RADIO FREQUENCIES.....which travels near the Speed of Light.

So they leave the transmitter and are recieved by your TV on the same radio waves.....
Kinda like you and your friend get on the same airplane and land in the same city at the same time.....there is no sync loss....

they are sychronized to come out at the same time, but If you were watching a tv from a mile away, (supposing it was loud enough and big enough to see) the sound would be about five seconds behind the picture. Does that help you at all?
