Run HDMI from DVD to TV. What about audio?
 

HDMI Ver 1.3 Off the top, do not know how. However, did read, will look
for link that describes the How.

Version 1.3 of what, HDMI? How?

Thanks.

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.

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!

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.

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).

1. Not right in the sense that it is a bad design, worthy of publicly
flogging the engineering team and their product managers.

2. Certainly familiar that these designers do make screwups of that scale
very frequently.

So let the TV set do the upconversion.

What a silly concept. There's no new information gained from upconversion.
It's original information they need to protect. This shows you the level
of intelligence of these content producers and why they should be put out
of business.

Not even from Chi^H^H^HWalMart which charges $12.

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
be a convenience to such circuitry, but it is by no means necessary since
that circuitry could apply any arbitrary sequencing of numbers itself.
All that is necessary is that at every step any equipment puts out audio
and video together, it must put them out already in sync.

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
wrong place to put it. This is nothing more than an attempt to shake
down consumers for even more cash by forcing them to buy something even
newer that very likely gains them nothing at all (just fix the broken
circuitry that is getting things out of sync).

www.crutchfield.com

has a good description of the difference if HDMI: 1.0, 1.1 and 1.3
at the present time most things use the 1.1 HDMI
