This thread splits off from the old $25 stripper thread:
http://www.curtpalme.com/forum/viewtopic.php?t=34454&postdays=0&postorder=asc&&start=140

Tom.W told me that he had a new stripper that was working for HDCP 1.4 with 1080p, but that the stripper / splitter was labeled as UltraHD. This is what the new splitter looks like.



There are several boxes that look like this on the market, and it seems that the ones with both the outputs next to each other and the input off to the side next to the power connector are using this board. We have seen two differently painted boxes (my photos show both), but both have the identical board inside.

There is another box that looks similar, but the HDMI input is between the two HDMI outputs. I have not tested that board.

So naturally we wanted to know if the new box is capable of stripping HDCP 2.2 on HDMI 2.x. Well after much delay I finally had the hardware and time to test it. Below is the test setup.



The source is my Murideo SIX-G HDMI generator sending HDMI 2.0 with HDCP 2.2. To make this a real test, I also tested with both Rec709 enabled and then Rec2020 enabled. I also tried HDR on and off from the SIX-G. For the experiment, the SIX-G is connected directly to the Murideo SIX-A HDMI analyzer for a control, and then connected through the new splitter. The results can be seen below:

Control: Murideo SIX-G > Murideo SIX-A


Results: Murideo SIX-G > Splitter/Stripper > SIX-A


As can be seen, the new splitter does indeed strip HDCP 2.2. It is also capable of passing both Rec709 and the Rec2020 flag as well as the HDR flag. Passing Rec2020 and HDR really surprised me.

The box does seem limited in that it looks to be only using a 9 GHz chip. So as far as I can tell, this box cannot do 4k @ 60Hz, only at 24Hz. That said, I did not experiment with different HDMI cables so it's possible that the box could do more with different cables (though I doubt it).

So there we have it, an UltrHD HDCP 2.2 stripper Smile You can find these off and on at eBay, Amazon, and Ali. They run around $45.

This is wonderful news for CRT owners (and for those struggling with HDMI 2.x and HDCP 2.2) because right now we have nothing that can do HDCP 2.2 on a CRT. With this box you could hook up an UHD BD player and set it to 1080p 60Hz or 24Hz and benefit from the improved color bandwidth of UHD. You could also connect to a Lumagen PRO and down sample the 4k to a lower resolution and run with that. There are more good reasons for wanting HDCP 2.2 on a CRT, but I bet others will chime in.

thanks for posting Craig. I was actually going to suggest starting an new thread as that old one is so bloated.

Will this thing cure the "HDMI drops" problem where the signal is lost and you have to unplug/replug everything? I don't have this but many people do.

It along with the old $25 stripper may very well cure the problem.

Hello Craig,
How these splitters work? I mean the outputs are in-sync, or are they at constant delay, or randomly delayed?

I'm not quite sure what you mean Embarassed

There might be some delay in the A/V, but I am sure it is almost no time; if there is any delay at all.

I mean the delay between the outputs, like if you'd want to split the HDMI signal for a CRT stack, how much would be the delay between the two projector's output? On newer video cards there is an option that the outputs are synchronized (even in digital output) so the frames are put on the output on the exact same time. There are applications where random (always changing) delay between the outputs are not allowable. So I was just curious how the splitters actually split the signal?

I think I'd better get my hands on one of these before someone decides that they're illegal and stops them from coming into the country.

Got it.

I have no way to test this, but I would expect the delay to be negligible or nonexistent. For the price, it's worth a try IMHO.

I've got this one few months ago and can confirm that it works without a problem. If you would like to play with it, you may have it for a week or so. I won't use my HT room for few weeks anyway. Just let me know...

Hi,

That's the previous one from the other thread (HDMI 1.3).

The model described by Craig can be found in Europe under the Ligawo brand. Model Number is 3080001. Just ordered one from eBay...

Regards,

The slitter I tested comes on and off the market. It does not seem to be consistently available. So if you want it and you see one, than my advice is to grab it quick. Right now they are available on Amazon.com and I just ordered another one Smile

http://amzn.to/291guDI

It also says, "4k2k@60Hz with 12bit YCBCR 4:2:0" so I may need to do some more testing.

I also checked .de, .co.uk, and .jp with no luck on those country's Amazon sites. I couldn't find any one eBay or Ali either.


This is the one that I specifically mentioned as having NOT tested. I do not know if it stripped HDCP at all or not.
http://www.ebay.com/itm/OREI-1x2-2-Ports-HDX-102-Premium-HDMI-Splitter-3D-Full-Ultra-HD-4K-2K-Support-/360975804344?hash=item540bd5a7b8:g:k4QAAOSw9NxTsVcf

This listing also does not say 4k or UltraHD either so probably not a good choice.

also, where would you put this thing. Just before the moome card, or do you need one on every source before it even gets to your AV Receiver?

Craig, I love those little HDMI testers. What's the cheapest place you've found to get one?

Well I did some more testing with multiple cables and here are the results.

I first tried the manufacturer's specified "4k2k@60Hz with 12-bit YCBCR 4:2:0," and it did not work. Here is a photo of the SIX-G connected directly to the SIX-A. Note that it is over 13 GHz. With the slitter, the signal did not pass. So this splitter does NOT support 4k2k@60Hz with 12-bit YCBCR 4:2:0 even though it says it does.

Control: Murideo SIX-G > SIX-A


I then tried 4k2k@60Hz with 10-bit YCBCR 4:2:0 and this also failed.

Finally, I tried 4k2k@60Hz with 8-bit YCBCR 4:2:0 and this passed! But again, this should work because it is below 9 GHz and I am now even more certain that this splitter uses a 9 GHz chip.

Experiment: SIX-G > Splitter > SIX-A


So you can get 60Hz 4k through the splitter as long as it's under 9 GHz. This means only with YCbCr 4:2:0 8-bit color at 60Hz.

You only need one, not both. If all you want to do is run HD 1080p or below than either splitter will work. If you want to use a 4k source with HDCP 2.2 than you need the newer one that I am demonstrating here.

Depends.

If your receiver supports HDMI 2.x and HDCP 2.2 than you only need one between the receiver output to Moome card.

If your receiver does not support HDCP 2.2 than you need one between the source to receiver for each HDCP 2.2 source. But, than you don't need one between the receiver and Moome card.
