There is a new Radiance Pro feature for use with the Kaleidescape Strato:
This release also has a new feature for the Strato where the Pro can use the HDMI Info Frame "Graphics Flag" (set while showing the OSD), to distinguish it from video content (HDMI Info Frame reports "Video"). Here is the overview:
The Strato only outputs its OSD at 50 or 60 Hertz. To use this new feature to speed up movie starts we program the Pro output 24 Hertz for the Strato OSD, and for 24 Hertz video, and then have the Pro output 60 Hertz for 60 Hertz video content. This allows us to optimize the time it takes starting Strato movies at 24 Hertz, and still have 60 Hertz video content show at 60 Hertz automatically. I first program the Pro to "match content" for vertical rate (MENU 0872 for 3840 wide or MENU 0877 for 4096 wide). Then I program the Pro to output 4k24 for the OSD (using the Graphics Flag to know when this is). To do this I first use the new menu entry Input.Options.HDMI Setup.Use Graphics Flag = Yes (or it will be named something similar). Then I use the Output Setup Menu to select the Strato-input-number for the Input column, "All" for Memory, and "Other" for Input Mode. Then select 4k24 (either 4096 wide or 3840 wide, as appropriate) for the Output Mode. Then press OK, and then EXIT, and then do a Save. As this implies the Pro uses the "Other" input mode detection (usually reserved for PC resolutions) for this new feature.
The Pro should be set to SDR709 for both CMS0 and CMS1, or SDRP3 for both CMS0 and CMS1, or SDR2020 for both CMS0 and CMS1. Also HDR Flag = Off, and 2020 < -- > 601/709 = Auto Convert. These settings eliminate the Radiance Pro output restart that happens going from the OSD (SDR709) to/from an HDR movie.
In the Strato IP setup interface you need to go to: Settings -> Video -> Advanced Video Settings -> HDMI Content Type Metadata, and select the "Transmit content type metadata" option.
With this feature a 24 Hertz movie starts, or stops, take about 6 seconds in our Lumagen Demo Theater. This is the time the Strato takes to change from its 60 Hertz OSD, to 24 Hertz for movie content, and for the Pro to lock on to the change. It includes the time to start the movie (which I also believe is around 6 seconds. I say this since switching input rate on the Pro without an output change takes about 3 seconds and this case should be the same. This indicates the output rate change lock-on time at the Pro input does not increase the movie start time).
This is one of those cases where owning the company allows me to get a feature no one else has even asked for
. However, I think many Strato owners will like the ability to start movies faster (at the cost of a slower start time for 60 Hertz Video content). Side note: This might prove useful in certain cases for PCs,
if the PC uses the Video/Graphics flags.
NOTE: I am not currently using the Kaleidescape "Costar" feature in the Lumagen Demo Theater. So I am not sure how content actually played form the "Costar" HDMI output (e.g. DVI discs not on the hard drive) will work with this feature. I have recently learned that content that is stored on the Costar hard-drive is actually played through the Strato. So this content should work with this feature.
