Author Topic: Blu-Ray player compatible with Barco DP100 Mike Olpin Chop Chop! Posts: 1852 From: Dallas, TX Registered: Jan 2002 posted 01-17-2010 10:08 PM                     quote: Eric Robinson Interesting, the ACS2048 seems to convert HDCP signals into non_HDCP signals which would be bypassing the whole purpose of HDCP. It does not do this. If you plug it into a non HDCP complaint projector, and then try to feed it 1080p via HDMI, it will either not handshake the source device, or it will display an error message on it's screen. You can however send 1080i via component video through it without any problems. The ACS-2048 does a great job scaling 720p and 1080i. No comb artifacts are visible on 1080i sources.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

If your DP2000 is HDCP compliant (they needed an option board for HDCP up until sometime in 2009)...then you can connect a BluRay directly...if you set your BluRay to 1080p and don't mind that the output will be constrained to 1920x1080...including scope (1920x804) and not fill the same screen as your DCinema Scope images.

It does output up to 1080i to devices not HDCP compliant.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 01-17-2010 11:40 PM                     Sam, it is more source dependent...it outputs HDCP, if HDCP source. As for its output rate...you are mistaken...it is always 2048x1080p at either 50 or 59.94Hz (user selectable). Since it was designed with DCinema projectors in mind, it knew they all could handle that with the frequency being country dependent. Your only other choices on output are the bit rates...8, 10 or 12 with 10 and 12 requiring twin-link connection (both DVI ports). Steve  |  IP: Logged Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 01-18-2010 08:56 AM                       I feel like I'm still married, always wrong. The ACS 2048 scaler is HDCP compliant, but this comes to nothing if the projector downstream is not. At least this is what I've been told by Barco and others knowledgeable in this area. In my experience with this, the Barco DP2000 would not accept 1080P until we upgraded it with an HDCP compliant TI board. After that it took 1080P content from the DigiDesign alternate content server as well as the Blu Ray player. We are using dual DVI and the projector is set for 12 bits.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 01-18-2010 09:04 AM                     Sam, I think you are confusing 1080p and HDCP being tied in some way. They are not. HDCP stands alone. You can play all of the 1080p source material you want (that does not have the HDCP handshake) with the ACS2048 on a non-HDCP projector. Again, it is the source that drives the HDCP part...the ACS2048 merely keeps the same copy protection as the source and hence is HDCP compliant...it doesn't strip it. The DP1200-DP2000 does indeed have a low-cost HDCP module available for them if they were made before 2009...2009 and beyond units are all HDCP compliant from the factory. Steve  |  IP: Logged Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 01-18-2010 10:49 AM                       So name some other readily available sources of 1080P apart from Blu Ray. This is exactly what most people want to play.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

And the BluRay would need to have its HDCP flag set. Steve  |  IP: Logged Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 01-18-2010 11:10 AM                       The title of this thread starts with Blu-Ray. Why don't you give a run-thru of this whole issue unless its been covered already someplace else? I know you know your stuff, but this is not helpful to directly answering the question in a direct and definitive way.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 01-18-2010 11:38 AM                     Sam, In terms of the progression of this thread...it was indeed asked relating a BluRay to DP100...which is fine unless the BluRay has its HDCP flag set. Mike Olpin, a user of the DP100 answered the question well, in my opinion (and I had not added anything at that point). Someone else brought up Gefen and I defended the ACS2048 over the Gefen and gave reasons. I also gave an example of a component to DVI scaler to get 1080 source material (analog) into the DVI inputs of the DP100. I'll admit, that a follow up clarification on the ACS2048, I did bring up the HDCP thing that would not help the original user but did better define the ACS2048's ability and what happens with HDCP sources. Your statements equating 1080i to non-HDCP and 1080p to HDCP are simply not correct...one is a resolution, one is a form of copy protection. If one were to set their BluRay to 1080i and it is HDCP protected, it still won't work on the DP100 on the DVI inputs. One would need to use the component outputs (not part of the HDCP thing) and have them converted to DVI for the DP100...using a device like the ACS2048 or other suitable scaler. I'm not trying to get into an argument or worry about being shown wrong...just pointing out incorrect statements so one does not draw incorrect conclusions.

I now have a much better understanding regarding the different formats and how HDCP might be coupled or not associated. It all starts at the source.  |  IP: Logged Geena Phillips Expert Film Handler Posts: 198 From: Norcross, GA / USA Registered: Apr 2006 posted 01-20-2010 10:20 AM                        quote: Eric Robinson We do have a Barco DP2000 which I believe is HDCP compliant; however, it sounds like a still need a scalar to make sure the image fits. Eric, we've got DP1200 and a DP1500. Ours handle the Blu-Ray image fine without a scaler.  |  IP: Logged Carey Barber Expert Film Handler Posts: 143 From: Newport News, VA, USA Registered: Jan 2003 posted 01-21-2010 09:41 PM                     We have an ACS-2048 hooked up to a Barco DP3000. We have had no luck getting Blu Ray to work through an HDMI-to-DVI cable. Component video works fine. Is this an HDCP issue? From my reading on this site it sounds like the ACS-2048 is HDCP compliant...So, is the projector itself the problem? If that is the case, is there definitely an upgrade that can make the DP3000 compliant? How much does this addition cost? Perhaps more importantly, is it even worth it, or is the difference between component and HDMI/DVI not that significant? Please note that this is all pretty new to me...Hopefully this is not too goofy a question. I have read this entire thread several times and it certainly sounds like our problem. How do you determine whether your projector is HDCP compliant? (This projector was installed in January of 2009.)  |  IP: Logged Kris Verhanneman Expert Film Handler Posts: 182 From: Belgium Registered: Dec 2009 posted 01-22-2010 02:53 AM                     On your question if this is a problem of HDCP yes it is. Can you do an upgrade on you Barco yes Is it wotrh it? Now this is my point of vieuw: non I've connected a blue ray on a dp3000 and projected on a screen of 10meters of height (and 25m large). The quality was impressive. I'm not sure if there will be a big difference if you input the signal in HDMI (and even worse, if your clients will see a difference).  |  IP: Logged Carey Barber Expert Film Handler Posts: 143 From: Newport News, VA, USA Registered: Jan 2003 posted 01-22-2010 08:30 AM                     Can HDCP compliance be accomplished through a firmware update or is this an actual piece of hardware that needs to be installed? Does anyone have an idea of how much it costs? This is mostly just for curiosity's sake...I doubt that we would actually purchase the upgrade, especially since component works and we very rarely need external sources. Also, I would like to be able have as much info as possible for my superiors. Thanks to everyone for all the info! Once again, this site has been incredibly helpful.  |  IP: Logged
