invention needed for out-of-sync TV audio

Audio out of sync with video seems to be a wider spread problem than ever before. Quality control perhaps?

Whatever the reason, I am highly motivated to find a solution. My hearing is bad and I supplement by "sort of" reading lips. And of course I use closed captions.

I've heard talk about different ways to ensure sound and picture stay somehow chained together.

But I've got a different approach. As a user I want:
- hand held remote
- has a dial to turn. the dial adjusts the relative timing of the audio and video. In one direction, it delays the video. In the other, the audio.

Desirable features: On/off, Presets, Delay-amount display

With that, I can adjust an old movie, a live sportscast, anything.

Ps. I want the same thing for the subtitles/closed-captions. It's funny how often I'll read the words before they're spoken by the movie character.

Coffee's for closers.

Are you connecting your TV through a A/V receiver?

If so, there's a "Lip Sync" option that should be turned on. The audio and video signals travel at different speeds over an HDMI cable, so this allows your audio signal to be clocked down to the speed of the video signal.

If you're getting audio before video, it could be a network and/or local station problem. These days, video coming in from a satellite or microwave signal goes through a frame synchronizer so it matches up with the in-house sync signal. Every time it goes through one of these devices, it delays the video a little bit. If it has to go through multiple frame syncs, the delay adds up.

Didn't see your post till now. The TV is connected a Direct TV box.

Thanks for the post. I've called Direct TV, but they say it's not them. Maybe it's as you explained. Whatever it is, it should be fixable somehow. If I had user controls, I could just fix it myself on a case by case basis.

I don't know if the audio is ahead or behind. or if it varies. When it's real close it's hard to tell which way it's off. But it sure messes up lip-reading.
