As television broadcasting has moved ever more into the digital
realm, I have been increasingly aware of the "lip-sync" problem.
This is where the words coming from the TV speakers are not in sync
with the movement of the lips on screen. This appears to be
becoming the norm these days in remote broadcasts, such as sporting
events like football games.
Last night, in observing the various New Year's Eve broadcasts,
this "problem" was in stark evidence. In fact, last night it was
not just the sound that was not in sync, it was the time as well.
Some TV broadcasts were as much as four or five seconds behind or
ahead of others as indicated by their countdown display clocks.
I'm guessing the time-shift was due to satellite delay for remote
feeds. I see this on DirecTV, comparing the local station's broadcast
of the network news, for example, to the New York station's broadcast
of the same program. A few up-and-down links will add up.
About the lip-sync problem, our daughter's DirecTV High-Def receiver
recognizes it as a potential problem in the trouble-shooting section
of the owner's manual, and lists several different things to do to
correct it. Apparently a well-known problem.
