Sony Blu-ray + Marantz receiver + HDMI = static or snow flashes ?

I see a tiny lip-sync problem with the audio going to the TV, at least
with HD channels being going through the cable box.



Audio sync with the video is always going to be an issue with the
program provider or transport to the receiver due to stream conversions.

Yes, the amount of sync error varies already in the material and
broadcast. I notice this far too often.

1) It _should_ be possible for both the production stage and the
distribution stage to do it right.

2) It _should_ be possible for a unit that process video and handles
the audio to introduce the needed delay to balance its own processing
delay. (Not every TV manufacturer bother to do this.)

3) It is the case where we split video and audio to two separate units
that needs cooperation between them. This is why an important feature
to have in the audio amplifier is a global ("lip sync") delay setting
so that we can (in average/normal material) balance the processing
delay in the TV.

With the newest HDMI version there is also (optional) a possibility
that the TV tells the audio amp or a receiver/ disc player what audio
delay is needed.

The amp and TV here offer the option of adjusting for this problem, but
I've only used it in the amp a couple of times, but it seems to work
well. Near as I can tell, it can handle several seconds of stupid when
necessary.

At least until they decide it's worth fixing. It's not that
difficult.

They could also have an automatic "correct aspect ratio" setting, and
even accurate color.

But people would rather buy bright color than accurate color, and
judging by setups in public places such as restaurants, they'd rather
fill up a screen than have accurate aspect ratios. So will the
providers fix the synchronization? Not unless they think it get them
more business.

Intermittent cutting out and showing snow, especially at the beginning

Hey, I have that. Sony PS3, Marantz SR9600 receiver. Usually I get one or
two blips within 2-3 minutes of starting a movie, or even a video streamed
from my PC. Doesn't happen again during the movie. It's done it about 75% of
the time since I got my PS3 in 2006.

I don't know what causes it, however the 3 HDMI devices I feed directly to
the TV don't exhibit this symptom.

That's about how I usually get it too - right toward the beginning of
the movie (which is also within a couple minutes of telling the
receiver that we're going to start watching Blu-ray).

The exceptions have been the times that the snow appeared 2 or 3
different times. Or, before the firmware upgrade, when I couldn't get
5 minutes through Iron Man without losing the sound altogether.

But, on the whole, what I see most of the time is just one single
round of snow:

2 seconds of snow.
2 seconds of black.
2 more seconds of snow.
2 more seconds of black.
then back to the movie.

I'm chiming in with a *me too* on this topic.

I have the same BD player (Sony BDP-S350). I plug directly to a
Toshiba 40" television via HDMI. All other gear is eliminated from the
picture an the problem persists.

After about 40 hours of video watching, I have concluded that in my
situation I:

a) Never have the problem with BD discs
b) Always have the problem with DVD's.

I'm running the latest firmware. Would be nice if Sony could address
this. It's not the cable, since BD's play flawlessly over the same
cable.

Anyone have more thoughts? Anyone else only experience this with
DVD's?

As the original poster, I'll mention that the problem went away when I
did two things simultaneously:

1. ran the HDMI cable from the player straight to the TV (which you
are already doing), and

2. purchased a new HDMI cable (about $10 or $12) -- one which
specifically states that it's capable of "HDMI 1.3a."

If it keeps up, and you're willing to spend $20 (cable plus shipping),
I guess you could buy the latest HDMI cable and see if your problem
goes away.

You might as well also get one which is "24AWG," which is better than
"28AWG."

Here's the one I got, although yours will cost less if you don't need
10 feet:

Are you attempting to up convert the standard DVDs? To what resolution?
Try a DVD with your BD player set to the DVD's native resolution of 480.
Still have the problem?
