HDMI 1.4a splitter to 1.4a and 1.3?

post #1 of 11
Thread Starter 
I want to be able to take the signal from my HDMI out on my Sony Bluray player and split it to send the signal to my Sony XBR-42HX929 and to my Pioneer AVreceiver. The receiver can't act as a switch for that HDMI device as it's not 1.4a and can't do the 3D stuff- sadly I bought it pre HDMI 1.4a.

Does any company make or sell such a splitter?

Yes, go through this forum's archives and you'll see lots of recommendations. That's the good news.

The bad news is that HDMI works by the lowest common denominator prinicipal since the cable only carries one video and one audio signal at a time. So, if you add a splitter with a non-3D AVR and a stereo TV, you'll receive a non-3D picture and stereo audio to both devices, if you use a splitter.

The EDID token is what is used by the sink devices (the TV and AVR in this case) to tell the source device (the Blu-ray Disc player in this case) what capabilities are available. You'll need to spoof the EDID so that the source device thinks it has a 3D device with multichannel audio. Those types of matrix switchers are available. The reason I mention a matrix switcher is that I don't know a regular switcher than has EDID spoofing available. Another option would be the "HDMI Detective" but then you would need to capture a valid EDID from a friends setup or someplace that both 3D and multichannel were available.

OK, now that I've probably confused you - here's one more. Since the audio is in a different part of the 3D stream than in a 2D stream, I doubt (but am not 100% sure) that when a 3D picture is shown, even if you do EDID spoofing, you'll get *any* audio through the AVR since the AVR wouldn't know where to look in the stream for the audio. With a splitter, obviously your TV won't have any audio either since you're sending multichannel and your TV only does stereo.

Now that we've gotten out the bad news, here is how I would solve this. Assuming your AVR has a multichannel input (with the RCA plugs), I would get a Blu-Ray player that has multichannel analog outputs and use those into the receiver. Then you don't need any type of splitter and the sound quality will be exactly the same as with HDMI. Make sure you setup your bass management properly (preferably in the AVR) for the multichannel inputs. That is critical. But, if you do that, you won't need a new receiver or a >$200 matrix switch and things will work the way you want them to.

If you don't want to buy a new Blu-Ray player then the only other option is a device that will provide 7.1-channel analog output from an HDMI audio signal. Those are available as well but may cost more than a Blu-Ray player.

Other than those options, if 3D is that important to you, you're on your way to spending more money on a new AVR.

Of course if you have a high end AVR and Blu-Ray player, the 7.1-channel analog outputs should already be there. It's just a matter of using high quality RCA patch cords to connect the two devices together.

Finally, just saying 1.4a doesn't mean that you get 3D or any of the other 1.4a capabiltiies. Every HDMI 1.4a capability is essentially optional - a manufacturer may or may not include them but can still list their device as a 1.4a chipset. For instance you can have a 1.4a TV that does not have 3D capability. So it was good that you listed 3D as what you were interested in rather than just saying 1.4a.

Yes, HDMI is really this user unfriendly (I got to post that twice this week - bonus points).

Good luck!

this one supposedly works for this purpose:

Great answer - probably works-- but is also 11 months after the question was asked.

Better later than never! I've been scouring the forums for a solution to my PS3 or PC outputting a 3D + DTS MA signal through my HDMI 1.3 receiver to no avail. When I plug in my new Benq 3D projector, I can see the 3D through the receiver -> projector only if the source is my PS3, but then I get no audio (I get audio fine in 2D). Via WinDVD on my PC, I can get DTS-MA audio but no 3D signal. It detects HDMI 1.4 and sees only the receiver being 1.3 and says forget this. /sigh. I guess HDMI 1.3 is good enough to pass 7.1 audio + 1080p/60 but can't send in 7.1 + 1080p/24/3d=48p? Doesn't make sense, 48p (24 in 3D) should be less bandwidth than 60p in 2D, so the audio signal should fit.

I HATE HDMI!!!!

all of this is some misguided attempt at copy protection shenanigans that makes all the real customers P'Od.

time to look at HDMI 1.4 splitters that do the job

Believe it or not, the answer to your question was only four posts above yours in this thread.

The reason a 1.3 HDMI receiver can't pick-up 3D audio is that the audio is in a different part of the HDMI stream for 3D. It's why you need a 1.4a chipset for 3D passthru (or a 1.3 that has been modified to be able to locate the audio stream).

The PS3 is a special animal. It is a 1.3 chipset but it has been reprogrammed to act like a 1.4a chipset mostly. It can output 3D over 1.3 and also send LPCM and DTS-HD MA (but not Dolby TrueHD) with 3D. So, it is a hybrid that is allowing your 1.3 receiver to send 3D. With any other 3D Blu-Ray player you would not be able to send a 3D picture.

As much as many of us dislike HDMI and its inability to expand gracefully, in this case it's probably not fair to say you hate HDMI for the audio stream differences. It's kind-of like saying you hate USB 1.0 because USB 2.0 is much faster. Everything is backwards compatible with the HDMI versions. It just makes it more difficult ot be forwards compatible.

Anyway, you also should read a few posts back to find out about EDID and Lowest Common Denominator before purchasing a splitter. It will probably not work for what you want (3D and multichannel).

Thanks, I'll read it all over more carefully. I did find a solution for my PC use of 3D and get all the audio I want too, I just bought a mini-display port to hdmi adapter for 25 bucks and now have no problems with multichannel audio and 3D at the same time, so I don't need a splitter. (I run the hdmi output of my videocard to my receiver, and the mDP directly to the projector. problem solved). It even seems to have stopped bugging me when I turn the TV off and the HDMI would re-handshake and try to pass the audio only to the projector's built in tin cans. somehow now my HDMI receiver will still receive audio even after I turn the TV off upstream. yay. this was very very annoying before (even in 2D)

On PS3 I'll try PCM mode in the hdmi audio settings. I remember the 3D went through on the blurays through the receiver but the multichannel audio didn't, so what you're saying makes sense. If I change the encoding settings maybe that's what it is. I do remember trying a bunch of output audio codecs for Prometheus on my PS3 to get some kind of audio thru my receiver to no avail, so I gave up and asked my friend to bring his optical connector so at least we'd have 5.1 instead of 2 channels (analog output)

thanks

Update : I tried PS3 via my receiver with TrueHD off and tried to use DTS-MA HD only, Prometheus and Sammy's Adventure both didn't work. So the issue if with my receiver, not the PS3. Looks like I got no choice but to upgrade my receiver. But damn, I need my pre-outs to my power amp, and this Marantz 5004 has been quite good to me for so cheap and TrueHD / 9.1 as well.

I guess I'm stuck with optical for 3D + multichannel audio on the PS3, not the hugest deal, but kinda sucky too. I guess I'll have to buy a new receiver at some point...but I'll wait to get 11.1 or something. / time to check the other threads for 2013 receiver tech

Hi people.

I have equipment:
- 3D beamer benq w1070 with HDMI 1.4 bluray 3D frame packing support
- AVR Pioneer 1018, with HDMI 1.3 (Dolby truHD, DTS-MA etc.)
- HTPC with nvidia gtx260 + nforce 9300 with Arcsoft
- Mediaplaer on Realtek 1186DD with HDMI 1.4 bluray 3D frame packing support

The same issues as have topic starter.

I've found splitter that have EDID corrector, Maximum (Mode 2) sounds good:

What do you think about?

If your AVR is not 3D enabled then changing EDID is not going to help.

There are a couple of 1x2 Distribution amps which can now insert a 'dummy' 2D video signal into Output B along with the HD Audio to allow 3D on A to your Display and HD Audio on B to your AVR - cost is the problem though, they cost as much as an entrly level AVR with 3D support.
