HDMI pass-thru

[gilch]

what does that exactly mean ...

[gearyt]

It means that the signal just passes thru like a piece of wire
no modifications, etc

[kingofgrills]

HDMI pass-thru means that what goes in comes out the back end

Here's an example of HDMI pass-thru for video:

480i ==> 480i

480p ==> 480p

720p ==> 720p

1080i ==> 1080i

1080p ==> 1080p

Here's an example of HDMI upscaling for video:

480i ==> 1080p

480p ==> 1080p

720p ==> 1080p

1080i ==> 1080p

1080p ==> 1080p


On the audio side of things, what I've seen out there is a bit murky. Basically, you need to watch for a lack of audio processing via HDMI. Some HTIB receivers have HDMI passthrough, but they don't process audio via HDMI. That leaves the listener without access to lossless audio tracks via HDMI.

...just remember, not all receivers upscale. And @ 1080p.

Any receiver/HTiB that states "HDMI Pass-thru" will NOT accept audio over HDMI. If you are considering buying one, don't, as you will not be able to listen to HD audio.

oh i see

Correct me if I am wrong....

My receiver does audio pass-through. meaning, it does not decode HD Audio. It accepts it over HDMI. So my PS3 does the decoding and passes it to the receiver. So while the receiver doesn't decode, it does accept which is just as good since 90% of people have it set up this way anyway.

So what I am asking is, if this isn't considered HDMI audio pass-through, then what is it called?

You have an excellent AVR, but nowhere do I read the term "HDMI pass-thru" in the Yamaha lierature, which is bacause that term does not apply. Your AVR can process audio via HDMI (though not decode HD audio as you mentioned). For your set-up, with player decoding, you have all you need. As I mentioned above, the term "HDMI pass-thru" means the audio and video are simply routed through the receiver to the TV (the receiver acts only as an HDMI switch).

sounds good. i guess i just thought it was only considered pass-thru since it was passing the audio through my receiver and to my speakers...

HDMI pass through has many different meanings and interpretations. However, one of the original definitions was that the receiver will pass picture (without processing) and audio to the TV through HDMI cable, but will not send the audio from the HDMI to the speakers.

This simply meant that the receiver could only be used for video switching. In order to send amplified audio to the attached speakers, you would have to run a separate optical, coaxial, or RCA cables to the receiver.

HDMI passthroughs to me are useless I have no idea why any one would even have them they do not amplify the audio. I had no idea this existed when I was looking at receivers. If HDMI does carries both video and audio and HDMI doesn't amplify audio, why don't you have the HDMI cable going directly to the display source? The only way I can see HDMI passthrough being of use is if you TV is older and it only has one HDMI input.

I find the HDMI Passthru very handy on my receiver.. when I don't want the surround speakers on at night and just want to use the TV Speakers I turn off the receiver and the singal passes thru the receiver directly to the TV for the TV Speakers to work.

That's not what pass-thru is. All HDMI receivers have the option of passing the audio thru to the TV, but if labeled "pass-thru" it means it does not have the ability to process audio via HDMI.

Which is better pass-thru or repeater

I asked before but got no answers probably because it was in the wrong thread group. I recently bought a Pioneer DV49-AV player and a Sony STR-DG1000 receiver and want to use the HDMI connection for the 7.1 and DSD decoding, etc. When I hooked it up, my TV was not handling HDMI input, power failure caused some sort of problem, and when I played a DualDisc the sound was in spurts. I attributed this to an HDCP problem since I then hooked up the receiver's HDMI output to my PC monitor with HDMI input, and the sound worked fine. Is this normal, require video with full HDMI compliance, to listen to a SACD or DVD-A when using the HDMI cabling?

To listen to SACD in its native DSD format, your player and your receiver must have HDMI 1.2 or above. In addition, the receiver must have the ability to handle DSD.

To listen to DVD-A, you need HDMI 1.1. As long as the receiver can handle multichannel PCM, you should be ok.

Both formats comply with HDCP. That is the main reason they don't work with Optical and Coaxial cables.

Your other alternative is to use multi-channel analog cables.

Some DualDisc releases have incompatiblity problems with disc players. Sony & Philips (the inventors of SACD) have never supported DualDisc. Most manufacturers have warnings on their websites.

Thanks for the information, I don't fully understand what you are telling me yet. I have read the SACD and DVD-A sections before, sort of what got me to this forum, but obviously some things are beyond my understanding. I thought you were suggesting that if I played a SACD in my Pioneer DV-49AV to my Sony receiver with HDMI I wouldn't have to have an HDMI video monitor. However I tried both an Andrea Bocelli "Andrea" SACD and his "Verdi" DVD-A (not Dual-Disc) and I still needed to have a monitor to play them correctly. I did discover that I can turn the monitor off after the disc has started playing so that is not too bad.

What happened to the days when listening to audio meant you didn't have to run macros to set up your amplifier? I like the HDMI cabling for the simplicity of one connection does all, but the HDCP seems to make life difficult unnecessarily - stupid pirating ruined it for all of us. BTW I did notice the receiver box says: "HDMI Intelligent A/V Selector (HDCP Repeater)" - I knew I could circle this back to the OP's original question.

Also some day I hope to build my own sub-woofer, just so you have to sleep on the couch

Something is not right. I never turn on my TV to listen to SACD or DVD-A. I use the Oppo 980 player and the Denon receiver. Previously, I used a Denon player and a Pioneer Elite player on a Pioneer Elite receiver to play SACD & DVD-A. They did not require the monitor to be on. Something must be wrong with your setup. Check the menu of the player and the receiver.

Is it possible that there is something special about the way they produced those two albums that requires the monitor to be on? I doubt that.
