New to HD & DishNetwork - A/V Sync Question

[tmoca]

First let me say hi...I am new here and am having a little issue.

I am new to all of this. I have searched the forum, but cannot find the answer to a couple of questions, specifically the cable question.

I have my dish receiver hooked up via HDMI (for video), however, I originally had a DVI-HDMI with my old cable box and the Dish guys gave me an adapter so I could go HDMI-HDMI from the Dish box to my TV.

My audio is running from the Dish receiver to my Sony receiver via an optical cable.

The problem is this. The audio seems to come through a fraction of a second BEFORE the video.
My question is this. What steps should I try to solve this issue? I have tried changing channels and also it doesn't seem to matter HD or standard channels.

Does having that HDMI/DVI adapter make a difference? Is it slowing the video signal down? Should I get a direct HDMI-HDMI cable and get rid of the adapter? Will the signal process faster, therefore matching my audio?

I have also read about cable quality and length. Both optical and HDMI cables that I have are quality cables and not very long.

Any ideas? BTW-I have not called DishNetwork yet.

Finally one last question a bit off topic. I have seen these optical splitters. Do they work good and without loss of quality? I don't want to actually split the signal, but I have an XBOX that is using an optical audio and I have a DVD that I want to use one as well, but my receiver only has 2 inputs and the Dish is using one.

Here is my set up
Vip 622 DVR box
Samsung LCD LN-T4661F
Sony STR-DE545 (no delay settings)

I hope this makes sense...I am a n00b here. Thanks in advance.

I was having the same issues with the HDMI port and had to switch to component. Haven't seen the problem again. Try the component connection (Red, Green, Blue) with (red and white) for audio.

I will give that a shot, but won't I lose image and audio quality that way?

No, you won't. I've compared both HDMI and component and they look the same to me. The only advantage is that HDMI audio and video on one cable, well at least to me.

TV 1 Audio sync

How is your TV 1 audio sync set? That is menu 6-1-7. It should be set to HD not SD. This could be the whole problem if some how it is set to SD.

I have to disagree with the "no video q lost" statement. Component is much softer than HDMI. To some it actually may be an improvement and not as harsh as HDMI, but there is no way that component looks "as good" as HDMI.

I would do what whatchel1 is mentioning. The audio sync setting on the Dish receiver is probably the issue here.

BTW I have my sat receiver connected to my Hitachi TV via HDMI, Component, S-Video and Composite for no other reason other than I can. So I have checked it out with my own eyes and some one else selecting the inputs blind. I could spot the difference every time between all 4 inputs. Sometimes it took me a while, but I scored 100.

The only way to correct my audio sync was by switching to component and I do have the audio sync set to HD on my receiver. It was driving me crazy specially when watching basketball and baseball, I could hear the swish of the basked or the ball hitting the catcher's glove so I knew what was gonna happen before it happened.

As far as the video quality, each TV set is different and in my opinion they both look the same on mine.

You will lose audio quality on the channels that send 5.1

No 5.1 or anything similar via composite (Red & White) cables. just plain jane stereo

But have you calibrated the inputs the same (component and HDMI)? I think most differences seen in the connections is based on the display setup. The only difference with component is there is additional D/A and A/D conversions going on.

Yes, take NEOSG advice and if switching to component use the optical output to your receiver for sound, which I think you mentioned you already do.

HDMI sends out discrete information for each and every pixel in the picture. Component sends out an analog signal with the information that is interpolated by the TV in lower resolution then upgraded at the TV. There just is not as much info being sent to the TV. No amount of adjusting will make compnent look as good as a properly set up HDMI connection.

Statement of fact : HDMI carries more picture information than component.
Statement of opinion: HDMI looks better than component. Coponent has a softer and, to some a much more pleasing look. HDMI has a sharper, more "crisp" and sometimes harsher look. This is also all source dependant. Statements assume 1080i source.

But we are getting away from the OP's original question which has to do with audio sync.

Currently he is sending DVI via adaptor to the TV and Optical to audio receiver. His audio receiver is getting/processing the sound before the TV is getting/processing the sound.

Option discussed so far:
-Check the sound sync settings on the 622 receiver in the set-up/preferences menu (I forget whish off the top of my head)

-Don't use HDMI for the Pix, use component video connection

Anyone else have any other suggestions?

I have one more myself... How about using the HDMI direct (no DVI adaptor) direct to the TV and then TV's optical out to the receiver. But check the sync settings on the 622 first.

I don't want to get off topic either but I have never read anywhere where HDMI carries more info than component and that component is lower resolution than HDMI and I find both hard to believe. If that were the case many more people would see a difference between HDMI and component. Can you provide some data to that regard, maybe PM to keep this thread on topic. Here is one of many links which agree with what I have said.

Hdmi is an all digital connection with no change in picture quality from transmission to recevier to tv.

Component is an analog connection that still does conversions in picture quality.

But then again hdmi does conversions in a different way before it is transmitted. Component can do hd but it is still an analog connection. There really is no difference in quality and it really depends on what cables you use and what kind of tvs etc. What ever looks best to you is the deal.

Take a look at this article and read up on it for yourself.

Agree, but I have a problem with a "conversion in picture quality". It coverts the signal yes, but does not necessarily change the PQ. The PQ has more to do with how the devices do the conversions and both HDMI and component can look great. So this will vary from setup to setup.

My problem with the earlier statements was that component is lower resolution and HDMI carries more picture information.

Isn't there some limit to what resolution can travel over component. whereas, HDMI is digital, and could support much higher resolutions

For example, I rarely see a display device that supports higher that 1080i over component. Higher resolutions than even 1080p should work over hdmi, when connected to say a computer monitor that supports higher than 1080p.

or is is just that the manufactures are making component enabled devices that don't support high resolutions over component?

 

[epaul]

See if you have a delay setting on your receiver, try adjusting same to slow down the audio.

1080p will pass over component, but you're right that very few devices output or receive this signal over component. I do not know the reasons.

And I'm not sure what the theoretical limit is on HDMI resolution.

No such setting exists on the OP's receiver.

My guess is outboard or external boxes are available that do (A/V processors) but they are spendy.

Oh, solution, (dang it), new receiver.

There just aren't any devices that are made to output an analog 1080p. All the equipment that outputs 1080p only do so in the digital domain.
