As part of the scaling process, digital filtering is used to enhance the image detail. This enhancement allows
standard definition inputs, such as DVDs, to appear to be much higher resolution. This is especially valuable
when standard-definition sources are viewed on the large screen sizes common in home theaters.
Commands can be sent to the Radiance by infrared remote or via the serial RS232 port. The RS232 port is
also used for software updates. Setup is done with the on-screen menu. User functions (e.g. select input)
use direct commands.
Configuration Memories
To understand how the Radiance functions, it is important to note 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 Output configurations are specified by
selecting a Mode, CMS and Style for each input, input memory, input resolution, and 2D/3D mode.
The Radiance has four input memories (MEMA, MEMB, MEMC and MEMD). Each input memory has eight
sub-memories that are automatically selected for input resolutions of 480, 576, 720p, 1080i50, 1080i60,
1080p24, 1080p60 and Other. The “Other” memory is reserved as a “catch-all” for unspecified resolutions.
Each Input sub-resolution memory can be independently linked to any one of the eight Output Modes, eight
CMS memories, and eight Style memories. These store setup data for the video display setup and
calibration. In the factory default condition all input sub-resolution memories are linked to “Mode 0,” “CMS
0,” and “Style 0.” To change these enter MENU → Output → Output Setup → (2D/3D) → OK →
(Mode, CMS, Style). These settings can be changed for each input sub-resolution memory. To “Save” new
settings, enter MENU → Save → Save → OK.
