Run HDMI from DVD to TV. What about audio?
 
I'm thinking of getting the latest Oppo DVD player and, for the best
possible picture, connecting it via HDMI directly to my new HD LCD.
Question: What do I do with the audio? My TV's got an optical-out.
Do I feed the optical-out from my TV into my receiver (which I also
don't have yet)? Is that going to cause sync problems? Or, do I run
HDMI from the DVD player to the TV and, at the same time, run fiber
from the DVD player to the receiver (if it even lets me do that)?
And, if I do that, then what becomes of the audio from the HDMI
connection? Maybe my TV's got a "no audio" feature besides mute (I
guess for that I can check the TV's menu). Anyhow, anybody have any
insight, anybody dealt with a similar scenario?

Thanks!
Kevin

If you're wanting to have the audio from your DVD player playing through
your receiver and not the TV, then, as you suggest, you should be able
to mute the audio from your T.V. through a menu selection and use an
optical cable to pickup the DVD audio. You will still need the HDMI
cable for upscaling standard-def DVDs. Otherwise, you could just use
component cables.

In a word, yes. Don't have your DVD player, but pick the best audio
out that the TV will accept.
And, if I do that, then what becomes of the audio from the HDMI
connection?

Turn the TV volume down when using the DVD player.

Similarly, I also made the HDMI connection between my STB and my TV,
as well as the (next) best audio out which I sent to the receiver.
That way, when watching HDTV I can either use the TV's speakers or the
Home theater set up

Run HDMI from DVD to TV. What about audio?
 
For my setup (TV - off the air antenna,DVD player, Receiver/Amp).

TV has 'speaker - OFF' (in menu), this is different than 'mute'.
Optical cable for audio from TV to receiver (used for OTA TV reception)
HDMI from DVD player to TV (also carries audio, but not used as speaker in
TV is OFF)
Optical cable from DVD Player to receiver for audio.

Supposedly there can be a lip sync problem if you send Standard DVD to the
TV where the TV does the up converting to its native resolution and send the
audio to your receiver. It is possible that the processing time in the TV is
long enough to notice that the sound comes out before the picture. If you
use the up converting in the DVD player instead then again supposedly that
can be compensated for.
I doubt that is the case, however I have never done any side/side
comparisons - from whence come flame wars.

If you use HDMI from up converting DVD player to a new HD TV, then you can
have the up converter do its job on all DVD's. If you use component instead
then the DVD player will not up convert to HD parameters for copy protected
DVDs (a legal thing).

For your setup of just DVD player and TV no amp at present, run HDMI from
DVD player to TV, will carry audio along, use TV speakers (note that in
general they are not particularly good.)

You did not mention what other source you will use (antenna, cable etc)
however if you are using a settop box that has HDMI out then you will also
want to use that, meaning that your TV should have at least 2 HDMI inputs.

Do NOT buy your HDMI cables from your local TV store! Way too expensive. Go
to the net and buy there. I got a 6' HDMI from an Amazon.com link for $2
plus $6 shipping.

Maybe someone can check my memory on this, but I'm pretty sure that I
had to disconnect the HDMI cable that I temporarily ran from my DVD
player to my TV because, once I had the HDMI cable connected, I could
no longer set my (Sony Bravia) TV to one of its aspect ratios when
watching DVDs.

As I remember it, I'm pretty sure the problem was that I could no
longer watch 4x3 DVDs at 4x3 ratio when the DVD player was connected
via HDMI cable.

Does that sound right or familiar to anyone?

I cannot comment directly on the Sony machine, I have a LG 42LB5DF 1080p TV,
LG DN798 DVD player.
Using HDMI on this setup does not preclude any of the aspect ratios that the
TV provides. (4:3 16:9 'set by program' and two zooms)

Run HDMI from DVD to TV. What about audio?
 
You asked me about more details for my setup. I have a Sharp Aquos
LC-46D62U (it's got 2 HDMI inputs) and I'm picking up digital signals
over the air. No cable, no cable box. The amp I'm thinking of
getting is an Onkyo SR605. I might be able to just run everything
through that amp's HDMI input (2 HDMI's in, 1 out). But I don't yet
fully understand how that amp will treat the video signal (whether it
will attempt to upscale it or what). That's why I wanted to know
about running HDMI directly to the TV and re-routing audio from the TV
back to the amp (just to do some homework, see what my options will
be).

Someone else mentioned that the OPPO 981 has additional audio outputs
(besides the HDMI feed). So, I might be better off just running audio
from the DVD player to the amp directly. Also, because of being
reminded about the copy protection circuitry, now I'm even wondering
if I would be able to use the optical audio out from the TV if I'm
using an HDMI source. I should check the manual again.

For HDMI cables, right... you don't need anything fancy. It's a
digital signal. If you're able to get a picture and there are no drop-
out's, you're golden.

Thanks again.
Kevin

I have the Onkyo SR605 and a Panny Plasma. For HDMI inputs the SR605 will
directly pass the video signals with no processing. The SR605 only applies
video processing on analog inputs to allow 720p on the HDMI output.

You will also need to send the TVs audio back to the SR605 for over the air
programming (optical or analog).

The SR605 has worked flawlessly so far, and has excellent sound.

Run HDMI from DVD to TV. What about audio?
 
Found this at an HDMI link:

Lip Sync: Because consumer electronics devices are using increasingly
complex digital signal processing to enhance the clarity and detail of the
content, synchronization of video and audio in user devices has become a
greater challenge and could potentially require complex end-user
adjustments. HDMI 1.3 incorporates an automatic audio/video synching
capability that allows devices to perform this synchronization automatically
with accuracy.

Yes, it would be interesting to know How.

Do I feed the optical-out from my TV into my receiver (which I also
don't have yet)? Is that going to cause sync problems? Or, do I run
HDMI from the DVD player to the TV and, at the same time, run fiber
from the DVD player to the receiver (if it even lets me do that)?
And, if I do that, then what becomes of the audio from the HDMI

As I understand, the display passes information back to the source on
how many milliseconds it delays the video. The source then sets the
audio delay automatically.
So it's the same kind of function we use in Surround amplifiers today
but it can be set more accurately (easier) and it would also change if
the amount of delay varies with different processing.
(It still requires that the material is correct and that the
broadcaster or user equipment doesn't ruin the syncronisation).

If they had designed a cabling system that packetized the video and audio
together, this would never have been a problem in the first place. Copy
protection would still work over this by encrypting those packets and use
a low bandwidth return stream to do all the display authentication steps.
Of course the manufacturers would not want to let people just use good ole
75 ohm coax, which is all it would need, as they need to find more ways to
rape the concumers' wallets and pocketbooks.

It's not the cable that gets things out of sync. It is the processing
circuitry itself. If that circuitry were to ensure that audio and video
were tagged together, this would not be a problem. Putting time tags on
the audio and video in the transport protocol coming over the wire might

It's not the cable that can bring them back in sync. The cable cannot
do that. The interface to the cable might, but that is absolutely the

down consumers for even more cash by forcing them to buy something even

You asked me about more details for my setup. I have a Sharp Aquos
LC-46D62U (it's got 2 HDMI inputs) and I'm picking up digital signals
over the air. No cable, no cable box. The amp I'm thinking of
getting is an Onkyo SR605. I might be able to just run everything
through that amp's HDMI input (2 HDMI's in, 1 out). But I don't yet
fully understand how that amp will treat the video signal (whether it
will attempt to upscale it or what). That's why I wanted to know
about running HDMI directly to the TV and re-routing audio from the TV
back to the amp (just to do some homework, see what my options will
be).


Someone else mentioned that the OPPO 981 has additional audio outputs
(besides the HDMI feed). So, I might be better off just running audio
from the DVD player to the amp directly. Also, because of being
reminded about the copy protection circuitry, now I'm even wondering
if I would be able to use the optical audio out from the TV if I'm
using an HDMI source. I should check the manual again.


For HDMI cables, right... you don't need anything fancy. It's a
digital signal. If you're able to get a picture and there are no drop-
out's, you're golden.


I have the Onkyo SR605 and a Panny Plasma. For HDMI inputs the SR605 will
directly pass the video signals with no processing. The SR605 only applies
video processing on analog inputs to allow 720p on the HDMI output.

You will also need to send the TVs audio back to the SR605 for over the air
programming (optical or analog).

The SR605 has worked flawlessly so far, and has excellent sound.- Hide quoted text -

The Oppo 981 has optical and coaxial digital audio outputs. Most AV
receivers now have more than one optical input. Some TVs don't pass
through digital audio from their HDMI inputs to their optical digital
output. Mine doesn't, so I use a separate path for digital audio to my
receiver. I've never noticed any audio sync problems with DVDs on my
Oppo 981, only with some digital OTA broadcasts.

higher bandwidth to enable 1080p and deep color (deeper than HDTV
specs). It also specifies changes in the protocol so that processing
delay times can be communicated between the source and the display. This
allows the two devices to attempt to counter the processing time to
avoid lip sync issues.

So you are saying the cable is not the source of the problem? Yet why
is the cable being fixed to correct the problem?

If something is doing some processing in the wrong way, then fix that
processing.


It's all about the communications. HDMI is a communications standard
that specifies the electrical characteristics of the cable *AND* the
protocol use to communicate over the cable. The cable is the medium for
the communications. Changing the protocol used over the cable requires a
change to the cable system specification. If there were no electrical
changes to the cable specifications, I would have called it HDMI 1.2.1,
but they changed both at the same time, hence HDMI 1.3.

The display would be able to do something like tell the player "hey, I am

slow at this".

It would really suck for games, though.

They should have ... from the very beginning ... just used 75 ohm coax for
the connection. They can still encrypt the data stream and do two-way
communications. With multilevel signals, the bandwidth can be quite high.

The audio should have been transmitted with the video, and time tagged.
Then the audio output to stereo systems would be from the display itself,
instead of requiring _every_ source device having to incorporate a delay
mechanism.

Additionally, a multi-device protocol would allow the source to device to
receive multiple display device keys over the same coax, and send multiple
decode keys in the main band signal. Then you can have a multi-room system
on one coax output (of the same program content).

But no ... the cable and connector manufacturers have to come up with yet
a new and more expensive standard.

the reason i bought the OPPO 981 was my long

at this point, the SACD has the higher sound
fidelity and bigger selection of real music
of all kinds (i've gotten only 5 SACD audio

rather excellent compared to the best CDs).
my A/V Receiver (AVR; a Denon 2307CI) is recent

more "upscale" in the number of I/O options

if you have any interest in getting SACD disks,
odds are you'll have to buy online from:
1. http://store.acousticsounds.com/store.cfm

the OPPO's HDMI output cable, *and* will your
AVR be able to understand that it is already
decoded?


The Onkyo's supposed to arrive tomorrow.



that should be interesting. :)

good luck with getting it set up. :)

assuming you're going to hook it up yourself,
it looks to me that you've got a lot of options/
alternatives on how you actually do it

e.g. my on-line glance (yesterday) at your AVR
suggests to me that it may be more convenient
than mine in terms of handling both video/audio
via the AVR's remote. i decided to use my TV
(a very recent Vizio 32") to do my video switching,
and my Denon AVR to do my audio switching.
fwiw, i currently have 4 multichannel audio inputs
into the AVR: 3 non-decoded optical (TV and 2 Panasonic
DVD recorders) and the decoded ext-in via the 6 RCA jacks

i can add that when i got my Denon i spent 5 hours (!)
trying to get it to work and struck out! i've done
computer s/w all my professional life so i have good
understanding of complexity. after sleeping on it
i turned to the troubleshooting at the back of the
manual and finally found page 49 where the digital

i'm not sure what DCDi means, but given that you appear to
have a recent 46" Aquos, upres of 480i to 480p by the AVR
isn't much. what caught my eye is that your new AVR specs
mentioned "Faroudja" which suggested to me that your new

is the native res of your 46" Aquos flatscreen

to offer you. i bought it coz of it's ability to

DCDi is an algorithm used for deinterlacing. With the Faroudja chip/
circuitry, it doesn't automatically mean that you get everything
converted to 1080p. It depends on how the Faroudja chip's being
used. I think my Onkyo converts 480i to 480p so you can use the HDMI
output. 480p should also be smoother visually. A site somewhere
mentioned a "trick" to get the receiver to do 720p but they said that
it only did a so-so job of doing that. Native res for my Aquos is
1080p. If you put a 1080p signal into the receiver, the receiver will
not attempt to upscale it but will simply pass the signal along to the
TV.

That seems to be well-known site for cables as I just ordered some
from there as well. I went with a couple 3-ft cables but I might have
to go with a 6. I could use the 6' from the OPPO and use the 3ft to
connect to the OPPO to the reciever since they're going to be sitting
close together.

There's also a site called ehdmi.com and I think it's the same store
as monoprice.com -- same layout, same catalog numbers, same prices,

can do to get the receiver to convert 480i to 720p but I hear it
doesn't do a great job of doing that. For 1080p, if my Onkyo sees a
1080p signal, it won't try to do any conversions on it but will simply
pass it through to the monitor.

DCDi is a deinterlacing algorthm. The Faroudja chip does it but just
because something contains the Faroudja chip it doesn't automatically
mean that you'll get 1080p from it. It all depends on how the
hardware uses the chip/circuitry. More info on DCDi if you're

It's all about the communications. HDMI is a communications standard
that specifies the electrical characteristics of the cable *AND* the
protocol use to communicate over the cable. The cable is the medium for
the communications. Changing the protocol used over the cable requires a
change to the cable system specification. If there were no electrical

but they changed both at the same time, hence HDMI 1.3.

I just want to reinforce what Matthew said about HDMI 1.3's lip sync
feature since so many people think that it really is "automatic lip-
sync correction" and it isn't. That's definitely a misnomer since
automatic lip-sync icorrection is actually impossible due to the fact
that there is nothing in the signals to define when they are or were
ever in sync.

As Matthew said the HDMI 1.3 feature is just a protocol (within the
EDID handshaking) allowing the dispaly to tell its source the fixed
delay it will add so the source (a/v receiver) can delay the audio
that same fixed amount but that won't solve about half of the lip-sync
problem because it varies from program to program and DVD to DVD. In
fact, most av receivers already have a delay feature you can set to
offset a fixed screen delay in a minute or two one time and all the
new HDMI feature does is set it for you saving you those few minutes
once since it's not going to change as long as you have the same
display. What's really needed is a way to adjust the delay in small
increments while watching without upsetting your program or movie and
so far I haven't seen any av receivers -HDMI 1.3 or otherwise that do
that which has created the market for the dedicated audio delays

Run HDMI from DVD to TV. What about audio?

Lip Sync: Because consumer electronics devices are using increasingly
complex digital signal processing to enhance the clarity and detail of the
content, synchronization of video and audio in user devices has become a
greater challenge and could potentially require complex end-user
adjustments. HDMI 1.3 incorporates an automatic audio/video synching
capability that allows devices to perform this synchronization automatically
with accuracy.


Yes, it would be interesting to know How.


As I understand, the display passes information back to the source on
how many milliseconds it delays the video. The source then sets the
audio delay automatically.
So it's the same kind of function we use in Surround amplifiers today
but it can be set more accurately (easier) and it would also change if
the amount of delay varies with different processing.

broadcaster or user equipment doesn't ruin the syncronisation).

I just want to underscore one comment Jan made about HDMI 1.3 helping
with lip-sync:

(It still requires that the material is correct and that the
broadcaster or user equipment doesn't ruin the syncronisation).

Only about half the total lip-sync error comes from the display's
video delay and that's all HDMI 1.3 will help correct. In fact that's
the same half you can already correct with a non-HDMI av receiver that
offers an audio delay. HDMI 1.3 could "potentially" rebroadcast the
required delay if the display's internal processing delay changed but
that difference is insignifiucant (perhaps 5 or 10 ms for a native
versus non-native resolution format conversion) compared to the 50 to
80 ms swings in "variable delay" already present in the signal when it
arrives. That variable delay comes from the digital image processing
starting with image capture and continuing through editing and post
production and broadcasting or DVD encoding. I have watched these
swings of 40 to 60 ms in incoming lip-sync error from program to
program on the same network and I've seen almost that much variation
from one DVD to another. As an example I watched Inside Man with
Denzel Washington the other night and it only required 19 ms of delay
(with my Felston Dd340) whereas most of the DVD's I watch require 60
to 80 ms on my plasma. That's a 40 to 60 ms difference between DVD's!
What's needed is an easily changed delay that doesn't disrupt what you
are watching so you can handle this changing lip-sync problem. Then
again, what's REALLY needed is a chnage to the broadcast standards
that would require a watermark or time stamp by the content producer
that true automatic lip-sync correction could use to restore lip-sync
no matter what happened to sync between production and viewing but I
don't expect to see that in my lifetime.
