Author Topic: IMB (and IMS) comparisons Nastia Motovilova Film Handler Posts: 30 From: Nicosia, Nicosia, Cyprus Registered: Sep 2012 posted 01-31-2013 05:24 AM                    Carsten, thank you for the super helpful description!!! quote: Carsten Kurz The Christie IMS fits only Christie projectors, as it needs the Christie TPC to be operated. Currently it's the only one that is able to ingest to and play from general purpose external NAS Did you mean to write IMB or do christie have their own IMS, similar to Doremi? I thought only one IMS currently exists on the market and that's from Doremi. Though I was reading on the GDC SX3000 IMB, and on their website they mention that it can come optional with Internal storage option - that I imagine would make it an IMS. Also does the IMS work with only projectors with an S2K chip? Why is this the case?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 01-31-2013 03:33 PM                     No, the Christie is an IMS, in that it also contains the SMS ('Screen Management System') and needs no external server. In other words, it's an IMB WITH integrated SMS, but with external storage. The 'S' in IMS does not strictly stand for 'storage' but for 'server' - which means, it is not just a MediaBlock in the terms of DCI spec, but it also contains the necessary software to play, control, schedule, ingest, etc. - the 'Screen Management System'. GDC uses the term 'standalone IMB' for their IMB with SMS. The Doremi IMS1000 includes storage (3 drive 2,5" RAID5) in/on the IMS The Christie IMS comes in two flavours - as a series-II IMS for Christie Series-II projectors (e.g. retrofit), or as a fixed installation within the SolariaOne S2k. Same specs and features, but not exchangeable. In the SolariaOne, the IMS is tightly integrated on board level with the rest of the projector electronics, not slotted. Hence it's not modular like the 'normal' Christie IMS. The Christie IMS works in all Christie series-II projectors, while the Doremi IMS should work in all manufacturers series-II DLPs. So not just S2k. The 'S' in IMS does not strictly stand for 'storage' but for 'server' - which means, it is not just a MediaBlock in the terms of DCI spec, but it also contains the necessary software to play, control, schedule, ingest, etc. - the Screen Managemt System. - Carsten  |  IP: Logged Nastia Motovilova Film Handler Posts: 30 From: Nicosia, Nicosia, Cyprus Registered: Sep 2012 posted 02-03-2013 10:24 AM                    I see. I based my previous reply on the article I've read at manice, http://www.manice.net/index.php/glossary/57-integrated-media-server-ims (bottom of the page) In the Doremi DCP-2K4 to Showvault-4 pdf manual, there's a Doremi IMb version for either Christie, NEC or Barco. So the Doremi IMB does work with most manufacturers of series II projectors. I imagine, there's only a handful of cinemas going with the IMS route, especially the one which integrates the storage in the projector also. Thanks for the great explanations Carsten!  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 02-03-2013 11:26 AM                        Ive spent some time with the Dolby & Doremi IMB/showvault and BD playback. With the Dolby you can only play content at the moment so no need to comment further until they launch their update unlocking the other inputs. With all IMBs we should remember these are in early phase of production I am sure software updates are to follow. A few observations with the Doremi that might be worth mentioning,it passes HDMI audio through the IMB 2 RJ45 connectors which is nice. I have yet to try 3D so I cannot comment yet. I do not like it converts the color space to XYZ, there is other processing and scaling taking place, there should be an option for pure pass through. All switching between source is done via the Showvault so you must have both the projector and Doremi running even for alternative content. When switching to HDMI or HDSDI you then choose your color space for that input, for BD Rec709 but the Doremi does not remember this so you have to repeat this every time you switch. The color space conversion might be off a little , remember XYZ is 2.6 gamma while most alternative content surrounds 2.2 and the default image is to dark so you will find yourself making adjustments to compensate or choosing a different setting when in device controller but again it will not remember your last setting. For these reasons I wish there was a unaltered pass through. The HDSDI is not working yet although they say it should be. I spoke with two different techs and got two different answers. One said the HDSDI will only work in duel projector mode which makes no sense, ether case it does not work. If anyone out there does have the Doremi Showvault/IMB combo with the HDSDI working please reply. I will give BD 3D a spin and follow up.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 02-03-2013 11:28 AM                     That's right. According to Doremi, the difference between the IMBs for different projector brands is actually more the 'faceplate'. There may be some small software/interfacing adjustments as well, but I'm not sure. - Carsten  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 02-03-2013 03:32 PM                        Concerning the Doremi 3D BD works great straight into the IMB HDMI port. No need for the Dimension 3D  |  IP: Logged Knut Erik Evensen Film Handler Posts: 10 From: Tromso, troms, Norway Registered: Jul 2007 posted 02-09-2013 05:27 PM                        The Doremi can play some DCPs that are packaged wrong. I had to repackage some DCPs to play them on the Christie. If you have to play strange DCPs at a film festival the Doremi is a safer choice.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 02-10-2013 05:46 AM                     Also, the doremi IMS has an Hardware Raid on it, which is a nice feature, imho.  |  IP: Logged
