Sound lag between TVs

by Angeline Booher / March 1, 2007 2:32 AM PST

I have 2 TVs with a digital cable box, one with just basic cable.

Usually the basic one in the kitchen and the digital one in this room are on. I've lived here for 4 years, and never had this before.

Say I walk from the kitchen to here, and the sound on this digital one lags 3 seconds (MS one, MS two, MS three) behind the basic TV. (I assume the picture must do the same.

I know that if this had been happening all of this time I would have noticed it. I don't know why this started about 2 weeks ago.

The cable company says this is normal re: basic versus those with digital boxes because the signal goes through the basic one first.

I'd like to know what you guys think.

for the living room TV. There's a TV in the kitchen. The one in the kitchen connected to normal cable is a bit faster than the one with Tivo. Guess the latter is bounced off a satellite or something.

the digital one has to decode the data first and it takes longer?

I think this is normal

but doubt you'll find the source of the delay. Of course the original signals are analog and need to be digitized and processed. If the feed was absolutely live, I suspect the difference would be less but, since there are tape delays and various methods of transmitting the signal types, I am not surprised they are out of sync. I have also had, in my own home, two PCs playing the same streaming data coming from the same cable to be a bit out of sync by a second or two. It seems odd as we think these signals which travel about the same speed as light....instantaneously to us...can be perceptibly different in their timing.
