Lip Sync Problems with New Digital Displays?

Posted by simoniker on from the kung-fu-movie-syndrome dept.

An anonymous reader writes "With all of the new digital TV displays flying out the door, its easy to to think that life is good on the road to high definition. But, as Audioholics reports today, cheaper displays are using inexpensive processors that result in video delays of up to 60 milliseconds (that's about 2 frames of video). This means that the video processing (deinterlacing, video scaling, etc) delays the picture so that the audio is out of sync. Add to this inherent delays in some LCD and plasma units and the problem can be more than a little noticeable. As of right now only a few manufacturers are building audio lip-sync delay into their products to compensate."

    I was wondering why Ron Jeremy's tongue was trailing behind the licking sound.

      Ron Jeremy is a personallity on FoodTV. He specializes in ice cream, thus the licking joke. I don't really see why anyone would want to watch such a fat man lick things but hey, to each his own.

      Previous poster is full of it! Ron Jeremy is a California-based businessman who's known for his length of service and enormous gifts in his industry.

      He's known to be a bit underhanded though. He's given the shaft to *hundreds* of co-workers.

    Now the lips in my old gozilla movies will be in sync! Deaf people everywhere are rejoycing!

      Yeah, those movies featuring rogue spyware programs smashing Tokyo buildings are pretty cool.

    Oh, wait. Those kung foo movies were always like that.

    There's no reason to build expensive circuitry to correct the problem. You can use the laws of nature to resynch your video!

    For a video lag of 60 milliseconds, you only need to step back 20.4174 meters from your TV before the speed of sound will correct the synchronization problem.

    I find that if I get ever so slightly drunk, the delay in my mental processing of the auditory information compensates nicely.
