How to bypass HDCP for use with Blackmagic Intensity (PS3 owners, read here!)

Meiru, I hope it is just a PSU issue. Worst case I'll send this one back and get the ViewHD if changing PSU does not work.

Tranq, I live in Scotland so temperature is never an issue. I do however have an idea I think might help other people with an Intensity product. Don't load the splitter with 2 outputs. Just run it for 1 output then use the Intensity to feed to your TV. That alone should help reduce the load on the splitter.

Hello everyone,
I'm sorry for the bump, but I would like to know if the splitter that Chokehold ordered (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=280840949481&ssPageName=ADME:L:OC:GB:3160) did indeed strip the HDCP? I myself want to record PS3 with HDMI, and this one unit would greatly reduce the cost of all the gear I need to buy.

If it didn't, I was then going to revert to the unit that Meiru originally posted (http://www.amazon.com/gp/product/B004F9LVXC/) except that seller won't sell to Australia. However, for that same listing, there is another seller who will ship to Australia. If I buy from that seller, would it be safe to assume that the unit I get from them will also have the HDCP stripping powers that the one Meiru bought had?

You have no idea how much this thread sparked hope in me after weeks of scouring the internet for a reliable source.

When in doubt, use explosives.

I am actually planning to test this tomorrow, since ironically, I didn't have enough HDMI cables to test with. And I'm at work right now. Sad

What I however was able to test, was the various error messages in the Elgato software. If I simply plugged the PS3 in, it said that the content was protected by HDCP.
If I went through the splitter, it just said that the software doesn't support the resolution, which I think was like 1440x1050 or some other obscure thing.

The manual for the splitter says though, that the splitter will conform all outputs to the max resolution of either receiving device.
For example, if the capture card can manage 1080p and your TV/monitor can only handle 720p, then the capture card will only receive 720p as well.
And I do believe my TV has a max resolution of 1080p.

By this time tomorrow, I should have an update for you on it all.

I look forward to your update. It's been such a hassle. I've seen all the other ways of bypassing the protection but it involved ordering from Monoprice, which would be considerably expensive due to me living in Australia.

If this works it'll be a godsend.

When in doubt, use explosives.

No such luck, unfortunately.
I haven't gotten it to work with the PS3 anyway, but that could very well be the Elgato being a total bitch.

As I mentioned, it did say that the material before inserting the splitter was protected by HDCP. It doesn't now, only that it doesn't support "1080p59,94" and then goes over to checking for a signal, then says it doesn't support 1440x1050.
So, I'm suspecting the device does strip the HDCP, but I can't positively and definitively confirm it due to Elgato being a bitch.
Sorry. :/

Ah well. Too good to be true I guess. I don't suppose you got a chance to try Meiru's one?

Okay. Well I guess I'll order Meiru's and try my luck. Thanks for the help anyway.

Try setting your PS3 to 720p and try again. Most HDMI capture devices on the market right now don't support 1080p at 60/59.94 fps, but should work just fine with 720p

Wouldn't that defeat the purpose of attempting to record with the HDMI cord in the first place? You can get 720p with component cables. Chokehold also uses the Elgato, which allows capture of unencrypted HDMI input up to 1080p, according to the site. In theory it should capture PS3 at 1080p if you can bypass the HDCP.

All the things

Technically you can get 1080p over component as well, but the reason you want HDMI is the quality difference. It may not be perceptible to your eyes in most cases, but having an all-digital source greatly helps encoding, and you'll get smaller filesizes and (probably?) less CPU usage as a result.

I did; no change. Still complained about not supporting 1440*1050 for some odd reason. Completely eludes me.

This is pretty much exactly why I want it to work. I did manage to capture at 1080p30 yesterday via component, so that might be what I'll go for, even though I do like the 60fps goodness of 720p.
This shit is hard. Sad

I'm going to order the ViewHD brand one. If you like I could post my results when my equipment gets here.

I have both of the Splitters (ViewHD mini and the one with the blue numbers). The ViewHD works perfectly with the Elgato and the Avermedia Game Broadcaseter HD capture card. As far as the one with the blue numbers I have the same issue when connected to the Elgato, black screen and it saying it does not support 1440. I connected this to my avermedia capture card and I got a display but when I tried to record the avermedia software said the video was HDCP protected. It seems like the splitter with the blue numbers passes some of the HDCP protection through the device.

Anyone of you folks tried HDMI to DVI, DVI to HDMI to wash out the HDCP?

HDMI to DVI works fine from PS3 and Samsung Galaxy S3, but the DVI to HDMI part goes absolutely nowhere. My DVI to HDMI is just a big unwieldy plug and not a cable and I wonder if it's broken or if I really do need a good DVI+Audio to HDMI converter. Some fella talked like it was hdmi to dvi cabling, dvi+audio to hdmi and done.

It seems that the only thing necessary to make this work is to add the audio from the HDMI and build HDMI TMDS frames or things will get weird, and the splitter posted here I see people saying it adds frames, it's on DX.com as a HDMI splitter.

(And I really want to cap me some Android speedrunning..)

e: dohhoho, that's on the first page of this. Alright I really want to cap some Android gaming dagnabbit.

e: http://dx.com/p/hdmi-1-3-pci-express-high-definition-video-capture-card-72046 does HDCP but no room left in my computer. Gess I gotta try importing that monoprice unit after all, not trusting anything even rumored to add lag frames

e: Reversed the cables and it works perfectly. Just not through the HDPVR2. Seems all Android devices by Samsung carry HDCP too. Effs sake.

HDMI and DVI are basically the same, both can have HDCP and both can also have audio.

No latency frames or nothing?

e: Tried ordering the Monoprice via amazon because I saw a few sources claiming international delivery but they appear to have been mistaken, awaiting refunds. One ViewHD like make of a HDMI splitter that worked (since many UK amazon sellers don't do business abroad) was http://www.amazon.co.uk/Cablesson%C2%AE-SPLITTER-Amplifier-Nendindo-Displays/dp/B0042KY0GY/ for 20 quid and cheap shipping. Ordered it, hoping it gives a latency-free experience.

All the things

On the latency side of things, I haven't noticed any. I haven't performed any more scientific tests, but my guess is that the delay is at most a frame.

Just some comments on how (I think) it is actually removing HDCP: typically splitters will have a requirement that the feed will be scaled down to the lowest requested resolution between all of the attached displays. This probably has to do with the handshaking process; the device is providing an identical feed to all devices, but if one of them cannot support that resolution then it forces that limitation on all other supporting displays. This is a direct passthrough approach, where the splitter only acts as the middleman in negotiating the final output resolution.

The ViewHD splitter in question does not follow this paradigm. It can instead provide feeds of differing resolutions to all connected displays simultaneously. This probably means that it is actually acting as an endpoint for the initial feed, decoding the HDCP, and then renegotiating resolutions with each connected display individually. This renegotiation process would not be possible if HDCP were still enabled. It seems like it was a design decision in order to make it easier to connect up devices that use different resolutions, and removing HDCP is just an artifact of that decision.

Hi guys I live in the US and I see that the link provided was for a seller in the UK so I used the model of it to find the following
http://www.amazon.com/ViewHD-Port-Powered-Splitter-1080P/dp/B004F9LVXC/ref=sr_1_1?ie=UTF8&qid=1360954913&sr=8-1&keywords=ViewHD+2+Port+1x2

And I just wanted to make sure from the people that own it that it is the actual model on the one's you guys got already.

I have a PVR 2 and want to take full advantage of the HDMI picture quality.
