Author Topic: HELP. color space ? for Dolby DSS200 w/ NEC1200c and realD Drew King Film Handler Posts: 14 From: Valley Centre Drive, San Diego, CA Registered: Jun 2011 posted 06-24-2011 01:56 PM                     I'm operating a Dolby DSS200 with a Real D system. Within DCC Our TCGD for the DCP macro is DC28_DCI_xenon and the picture looks correct, this is confusing because what I understand DCI content should be XYZ. I have played about a dozen different DCPs encoded from different vendors and they all look correct using the xenon TCGD. When using the XYZ TCGD the picture is completely out of range looking very pink. Something is fishy... I see that the realD Control Module that is mounted in the rack has an LED display that says REC 601 full range which would be wrong since that is YCxCz, but there are no SDI cables routed in our out of the realD so I assume the color space is not being affected here. I also switched the Equalization and Video Settings switch to disable this (the only switch on the front of the Control Module) rebooted and it made no difference. I need help thanks in advance because I know you folks are going to be able to help me in some sort of way.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

What you really want is DCI(P3) for the Target Color. And the color space should be set to Scaled_240M_0_1023. Note, these settings only apply when using the Dolby brand servers. -Steve  |  IP: Logged Drew King Film Handler Posts: 14 From: Valley Centre Drive, San Diego, CA Registered: Jun 2011 posted 06-24-2011 03:21 PM                     FASCINATING! i will respond again once I can test.

There are several different color spaces being used for 3-Deee.

I don't have any equipment to do any measurements so I cant give any specific feedback. Is there any documentation that supports these statements of xenon being for testing and the 240m being for dolby servers?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Real-D does indeed have a document that calls out what settings or PCFs they are looking for on the various players. If you have the TI DLP program and suitable passwords...etc, you can see what changes when each file loads to see what each are doing.  |  IP: Logged
