I was in my bedroom down the hall from my moms room and I we were watching the same thing in two seperate rooms. Anyway, I could hear what was being said before her tv said it. Why is that? It also happens when your on the phone with someone who is watching the same thing on tv.

One of you has a digital cable box and the other has an analog cable box. The digital has buffers which slightly delay the broadcast. It's cool huh?

Depending on how you receive your signal, what type of signal and the distances involved, there are delays in signals.
A satellite signal will take a bit longer to receive since it has to travel from the ground to space and back again before arriving at your home. The signal was probably already transmitted this way once to begin with in order to get to your provider.
A digital signal may also take longer to 'receive' since the signal must be processed into a digital format, compressed, sent to your home and the processed and decompressed.
Satellite signals typically undergo the compression processing as well contributing to the delay.
Also, keep in mind that if you have cable that has a distance of 1 mile to your cable provider and your friend has the same provider but is 30 miles away, there would be a delay of his signal as well though far less noticeable.
Additionally, your provider may be broadcasting at a bit of a delay for various reasons.
There are other things that can contribute to this delay but overall it is usually distance and processing time that affect this.

How much earlier did you hear it? It takes sound a while to travel and it can be a noticeable difference. Most people can easily detect a difference of 100 or 200 milliseconds. Sound travels at 1,130 feet per second so if the other tv is more than 100 feet away you could detect the delay.

This will happen if you are watching the same program but one of you is watching it on an HD channel or if one of you is on a digital feed and the other is not. We got the same effect between our cable fed t.v. and a small one in the kitchen on an antennae.

I think it's the internal processors on individual TVs. Some may not work as fast as others, even though they may receive the same exact signal.

Were you each watching the same show on the same channel?
I have noticed this when I change channels between two affiliated of the same network. They don't keep exactly to the same times.

If one is on a satellite and the other is on an antenna there will be a difference. One signal has to go up to the satellite and back.

You have two different TV providers

One Tv's reception is faster than the other one. Don't think this is a health issue but a technical (TV) one.

That happens to me also. One tv is slightly ahead of the other. Don't know.
