Why a delay in television reception?

[LSLGuy]

I’m sorta old school on baseball. So I listen to the live AM radio braodcast over, you know, real over-the-air AM radio. And watch it live on the TV over real, over the air, broadcast from our local station.

There is often a 4-10 second difference. Usually (always?) the TV is behind the AM radio. So we hear the catcher catch the ball, the AM commentator calls it a strike, then we see the pitcher throw it.

I do something similar. I will watch a game on TV, but listen to the local “radio” station via streaming audio on the Internet.

The audio from the net is usually 30+ seconds behind the feed on the TV. So, I pause the DVR on the TV and attempt to sync the two signals.

While this works, after about 1/2 hour they are two or three seconds apart again (either way) and I have to adjust. So many variables involved that would prohibit 100% accuracy..

I listen to the radio through iTunes on my computer, which tends to be 30-45 seconds behind broadcast. Many times I’ve pulled up to the house just as the news was coming on. I shut the car, go into the house through the garage, go down to the basement where the computer is already streaming the same station, and the news is just coming on.
