Configuration Memories
To understand how the Radiance functions, it is important to understand that setup and calibration
parameters are split into “input memories” and “output configurations.” Input memories control the video
source setup. Output configurations control the display setup and calibration. The Input Memory selects the
Output configuration for that input, and input memory by selecting a Config, CMS and Style for each input,
input memory, input resolution, HDR/SDR, and/or 2D/3D mode.
Each Radiance Pro input has four input memories (
MEMA
,
MEMB
,
MEMC
and
MEMD
). Each input memory
has sub-memories for each supported input resolution and rate which are automatically selected based on
the input resolution and vertical-rate.
The “Other” entry
is selected for input resolutions and vertical rates
not specified explicitly. Each input resolution and vertical rate has 8 sub-memories which are programmable
on a per-input and per-input-memory basis. For example, as shown in the block diagram below there can be
8 different input configurations for 480i/p sources. Different inputs and input memories can each be
independently programed to one of the 8 sub-memories for each listed resolution and vertical rate.
Each input sub-memory can be independently linked to any one of the 8 Output
Mode
configurations, 8
CMS
memories, and 8
Style
memories. These store setup data for the video display setup and calibration.
In the factory default condition all input sub-memories are linked to
Auto
output
Mode
,
CMS 0
(for SDR
sources),
CMS 1
(for HDR/Rec2020 sources), and
Style 0
.
To change these linkages use the
Output Setup
menu. Settings can be changed for each input sub-
memory. Make sure to
“Save”
any changes you want to keep (
MENU
→
Save
→
OK
→
OK
→
OK
).
NOTE:
By default, for a Rec 709 source, all sub-memories point to Auto output mode
CMS0 and Style0. For a HDR/Rec2020 source, all sub-memories point to Auto
output mode, CMS1 and Style0. For the majority of systems this default set of
configuration pointers does not need to be changed.
NOTE:
Changes must be Saved. If changes are not Saved the Radiance Pro will revert
to the previously Saved settings when turned off. So, if you make a
configuration mistake you can revert to Saved settings with a Power Cycle.
