SOURCE: Sound/Video delay
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. Here is the review I mentioned: [URL="http://www.audaud.com/article.php?ArticleID=3011"]
SOURCE: theres a delay when i play my xbox 360, why?
go to your picture menu and go to advanced video then go to DCM and turn it off. it should work i had the same problem if that dont work then try turning off the dynamic contrast and adaptive contrast along with the DCM. if that dont work then im sorry.
SOURCE: what causes delayed ignition, causing a slight
There will be a web or bug or debris in the pllot asssembly /rail that blocks the path of the transition to main burner or ignition of pilot assembly itself, when it does ignite, theres too much gas built up in the pilot ignitor area and it explodes, clean the orifices in the pilot asssemblt / and or the pilot rail or main burners orifices at the pilot area.
SOURCE: Just bought a Sharp LED TV and there is a slight
Hi if there is an optical out on the television i would use that direct to your Harmon Kardon AVR 125, the sound would be in sync with picture, as the source is the same.
