Since light moves faster than sound, why is the radio broadcast of the Cavs game ahead of the tv broadcast?

Question

I enjoy listening to the Cleveland Cavaliers radio broadcast (Joe Tait is the best play by play man in the world) but when I try to listen to he radio broadcast as I'm watching the television, the radio broadcast is about ten seconds ahead of the television. Why do the television images (which I'm assuming are made of light?) lag so far behind the sound waves?

Answer 1

The stations use compression software to compress the digital information in the video and audio to a much smaller number of bits before sending it to the cable companies and to the broadcast tower. that compression takes time, so the entire signal is delayed a few seconds to allow for that, and to synchronize the video and audio. High-def signals particularly take a lot of time to process. Although from what I've seen, a few second's are more than enough, so there may be some other factor that is delaying the signal.



It's also possible that there is a censor delay in case someone says the wrong word, there is time to blank it.



So all of the signals move at the speed of light, it's the computations that take the time.

Answer 2

Because TV has a 12 second delay, and Radio only has a 7 second delay.
