Is it possible to setup lip-sync on the DB940?

Lip-sync is a cumulative problem with potential errors entering at any stage in the broadcast chain where video is delayed and an equivalent audio delay is not added to counteract it. It can occur during post production, broadcast (at many stages), and even in disc mastering - and finally your TV may add more video processing delay (especially if HD or 4K TV) making it worse. The only way to correct it completely and have perfect lip-sync is to adjust (or shift) the audio relative to the video at the final output stage. That can fix lip-sync error no mater where it came from.

Since it has been documented that lip-sync error - even when not consciously noticed - causes viewers to perceive the characters and story as "less believable" , many cinema enthusiasts use external delay boxes made by companies like Alchemy2, Felston, Primare, etc.to intercept the audio and delay it to match the video perfectly via remote control.

I use a Felston DD740 and contrary to what the industry believes I can detect lip-sync errors down to the millisecond. I mean when I adjust the DD740 and achieve what looks perfect moving it a ms either direction looks "off". Most viewers will never see "perfect" lip-sync if they aren't performing such an adjustment while viewing.

Getting it "close" - perhaps within 30 or 40 ms - will allow most viewers to ignore it but the study done at Stanford showed the negative impact was still present.

The current theory to explain this is that our brains - even subconsciously - can't process the impossibility of sound before lip-movement and we look away from the lips to avoid the impossible and in doing this we form the same opinion of the characters as we have of people who don't make eye contact with us. Ironically "we" are the ones not making eye contact with the characters in order to avoid the impossibility of sound before lip-movement.

You can run your own test to prove this: Force yourself to focus intently on the lips and you will see lip-sync error you never noticed before. You were ignoring it because it was below your "threshold of recognition" and looking away could conceal it.

After the cable change and adjustment you didn't notice lip sync error because it was probably below that threshold but something ( a digital video effect in the broadcast possibly) boosted it above your threshold and you noticed it again. The only way to eliminate the negative impact is to look for the error and adjust it out.

Most AV receivers and some recent TV's offer a fixed audio delay to correct lip-sync error and that can usually get it close enough that most people won't consciously be bothered but masking the problem like that doesn't eliminate the negative impact on the characters and story.

I don't see a question. Are you asking about a lip-sync problem and how to correct lip-sync error? If so I need more detail to answer your question.

should be in set up menu in denon receiver

Vizio HDTV- Lips out of sync

Anyone with a new Vizio E601i-A3 60" or 70" HDTV that is having audio "Lips out of sync problems" with a cable or satellite box.

On Comcast cable boxes (or others), here's what you need to do: FIND MENU for AUDIO or HDMI setup on CABLE BOX or Satellite Box.

FOR COMCAST

1. Turn on TV and have Cable box Turned OFF.

2. Press MENU on COMCAST REMOTE.

3. Go to AUDIO Setting OR HDMI Setting. (On cable or Sat. BOX)

4. Change setting from Auto to L-PCM. (Turn off cable box to exit)

This should resolve any "out of sync" lips to picture after commercials on HD channels.

*This is a handshaking issue from the cable box to the Vizio E601i-A3

Have you connected the Blu-ray player to an AV receiver. If so you can go into the setup of the Receiver and adjust the Lip Sync in some receivers its called Timebase Correction. It will be given in milli seconds. This adjustment allows the use to delay the voice in milliseconds to sync with the picture. Maybe even your Bluray player setup might have this feature. Mostly it is done by the Receiver.

Hello did you find any solution ?
I have exactly the sams issue with the harmony one and the STR-DB940 and I don't find the solution till now

RX-V465 has auto-sync feature over HDMI. So if you have your DVD and TV connected over HDMI, receiver will communicate with your TV and set the delay automatically based on TV processing speed.
You can turn auto-sync on in Setup menu / Sound Setup / Lipsync / HDMI Auto.
Or if that doesn't work for you, you can set a value in milliseconds manually in the same submenu.

You start lips up and turn on the microphones, They start flashing green slowly then hold the power on the mics again and they flash green faster then press the sync buttton on your xbox360 the small button next to memory card port. The mic lights will go white quickly and start to glow when you play the game

Lip-sync error is a widespread problem caused when video is delayed and audio arrives too soon. Widespread enough that three different manufacturers make dedicated products to address it, in fact (see review link below for those three). It is present to some extent in essentially all broadcasts and DVD?s. If you have a recently acquired DLP, LCD or plasma display it may have added enough additional video delay to make it noticeable but lip-sync error comes from MANY sources starting at image capture and continuing through post production and broadcast or DVD encoding and it is cumulative. There is usually enough lip-sync error in broadcasts and DVD's to cause a negative impact on viewer perception (Research done at Stanford showed this.) Many people don't consciously notice it until it gets very large because it's such an unnatural phenomenon ( audio can't come before the action causing the sound in the real world) we apparently subconsciously avoid looking at the faces and seeing the lips move "after" the sound from them is heard. A study at Stanford proved this causes negative viewer perception even for those who don't notice it so this is something we all need to notice as you already have. For those reading this who haven't noticed it, take a close look at the LIPS - force yourself to overcome your natural avoidance mechanism that keeps you from looking at the lips - and you will see lip-sync error you never noticed before. I think you will be amazed that you could possibly not have noticed it before. You will be seeing what JC is seeing. I even see it now on CRT TV's and am amazed I never noticed it so it's very obvious some avoidance mechanism is at work. And back to JC?s solution: I'd recommend one of these digital audio delay units. That way you can correct for ALL cumulative lip-sync error no matter what its source might be. Any one of these units reviewed will correct it ALL. With any one of these units you can adjust for perfect lip-sync at the start of each DVD or broadcast and not disturb the image you are watching during that fine adjustment. I have had a Felston DD340 since 2004 (three generations earlier than the DD740 covered in the review) but it still has the most important feature of all these units from these three different manufacturers which is their "plus and minus" buttons on their remotes that allow you to tweak the delay while watching your material without upsetting the video your are watching. My av receiver has a built in delay of 80 ms which isn't even enough audio delay to offset the video delay my plasma display adds but even if it were it isn't practical to adjust it for the changes in lip-sync error from program to program and DVD to DVD since it overlays the screen with menus when making the delay adjustment. With my DD340 (and any of the units reviewed) all you have to do is press the plus or minus button until you get perfect sync.

if you are saying that your tv has no sound to match the lips movements then you will have to get a tech to repair your tv the problem is in the audio circuit could be a cap or the audio output ic.if you are saying that the tv has sound but it is not syncronizing with the lip movements have your tech check the sync circuit it is possible that the operating voltage is too small to allow the sync circuit to operate.good luck my friend.
