Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 11-12-2018 06:56 AM                     I'm not saying it can't be done with automation but now you've added another requirement and, if you are using say a GDC IMB...how are you selecting/cueing up the HDMI show, specifically to have it switch its input? On the Dolby/Doremi IMS...I don't recall if one can directly cue it to switch inputs either. The Dolby DSS line and the Barco line, you can. Crestron/AMX type external automation is not going to go into any but the most sophisticated theatres that, quite frankly, will likely have an operator to guide the show. Having a pedestrian automation handle switching picture and sound is no biggie. As for Carsten's post, no, no mention of what their issues were...for all we know, they don't handle HDMI 2.0 (likely don't). Aside from that, likely whatever issues they have, they are software problems that can be corrected. I have not played with the DCIO-H yet but I did pop its lid and it has a big chip in there with both the Dolby and DTS logo so it isn't like QSC is reengineering something from scratch. There is a FB group I belong to where they have shown the DCIO-H decoding DTS Master HD (which QSC doesn't claim it can do...just the next tier down of DTS-HD...no-master). There could have been other reasons for them to ditch the DPM in a residential/consumer application too. You'd have to ask them. The DPM is a digital cinema processor first and foremost. The HDMI input is the accommodation for consumer and alternative content stuff.  |  IP: Logged Sean McKinnon Phenomenal Film Handler Posts: 1712 From: Peabody Massachusetts Registered: Sep 2000 posted 11-15-2018 10:28 AM                        I have installed a few of the DCIO-H's (with core 110's and 510's) and the HDMI decoding/routing has been painless. The decoding of Dolby or DTS-HD is automatic if the bit stream is received by the unit so simply setting your blu ray player (or whatever device) to that track or setting is all thats needed. There are no special Q-Sys modules involved. As anyone who is familiar with Q-Sys knows it is also very easy with a router component or matrix mixer and snapshots to set-up whatever kind of routing you may need. The only caveat is that you cannot use both the HDMI input and the channels 9-16 AES3 input simultaneously but I would be very surprised if that ever becomes an issue!  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 11-16-2018 07:45 AM                     I come from a world where the same pins on a CPU handed both the DATA and the Address so one had to switch those too via the ALE pin (Address Latch Enable) (Think Intel 8088) and segmented memory. Matrixing the HDMI outputs and the AES outputs isn't a big deal! With consumer formats, you are going to have to do some channel housekeeping anyway. For them, a 5.1 format doesn't play ANYTHING out of the rear surrounds (like our 7.1 format when someone plays 5.1 with it selected). Also, the surround levels in consumer are not the same as cinema...we, unfortunately, have clung to our legacy of mono surrounds going back to the 1950s so each side is at 82dBc for 5.1, each surround channel is 82dBc for 7.1. Consumers wisely realized that mono surround has no place in the digital world so each channel is the same (surround or stage) so if you set your surrounds to 82dBc, you'll need a 3dB boost to get them up to consumer levels. I'd presume the DCIO-H doesn't automatically decode 2.0 content via pro-logic so again, some overhead is needed there. QSC has really be working on QSYS in these areas so you have the tools to do pretty much what your imagination can come up with. I think other than noise reduction, one can probably do everything an analog film processor does within a QSYS system, including for 70mm formats. I've even been piecing together a Perspecta Stereo decoder in QSYS.  |  IP: Logged
