Apologies if this has been mentioned before...

For the first time since getting my Humax Foxsat HDR a couple of months ago I put it on ITV the other day and saw the "Press RED to watch in HD". "Great", I thought to myself, "this Billy Connolly programme will look good!" So I pressed RED, and almost immediately my girlfriend said, "Yeah, HD might be great an' all, but they can't get his lips in time with the sound!". "Aha!", I said, pointing upwards, "the Humax can handle that!", and I proceeded to fire up the Lipsync setting.

Here's the problem; The sound on the broadcast in HD was slightly behind...as far as I know it's always been behind whenever I've seen this issue on TV before. In the Lipsync section on the Humax it appeared that I could only slow the sound down even more. The slider started all the way over on the left, and each press right made the sound another 10ms slower.

What on earth is the point of not being able to adjust it both ways, or am I missing something?

So I pressed BLUE and settled for watching it in SD with the sound correct.

Happened last night on "Wild At Heart". The usual fix tune to 101 and back to ITV HD fixed it, so far (touch wood) when this occasionly happens this has fixed it

I was able to cure this on Billy Connolly by switching the Dolby sound off on the Humax. It was my first dabble with ITV HD so it will be interesting to see what happens this week.
Not sure if it was the move out of the ITV HD environment as Graham mentions or if it was the Dolby adding to the processing time. Experiment to be continued ....

I've NEVER had lipsync issues with HD on this box, either on BBC HD or ITV HD.

But..... I never watch Live, I'm always watching played back scheduled recordings.

Do people still see lipsync issues on their recordings?

Rgds.


Les.

The recordings show lip synch problems when it's genuine broadcast problem. Last night's wild at heart initially out of sync watching live (until fixed as posted), the recording shows no sign of the problem (weird I know )

Last night's Billy Connolly seemed fine, so I guess it's more a Humax/sound issue than a broadcast issue.

Still doesn't make sense that you can only adjust the lipsync one way though.

I think it would be quiet hard technically to do it the other way. Delaying the sound is relatively easy doing the same thing to a HD video stream must be much harder if only because of the massive increase in data to handle (a much bigger buffer would be needed). Would be interested in comments from those more aux fais with the technical difficulty in acheiving this. Certainly my top of the range AV amp can only delay the sound and not delay the video.
