Circuitry
To accommodate the full range of SD, HD, computer and Digital Cinema
inputs, the projectors have four input slots that accept optional input boards.
Optional Input Board Description
LKRI-001 Analog Input Board
LKRI-002 HD-SDI, SD-SDI (4:2:2) Input Board
LKRI 003 Dual-Link HD-SDI (4:4:4), Single-
Link HD-SDI (4:2:2) Input Board
LKRI-004 DVI Interface Input Board
Internal signal transport is accomplished by Low Voltage Differential
Signal (LVDS). The projectors can put a single SD, HD, computer or Digital
Cinema image across the entire screen, show a quad split of four simultaneous
images, or show two simultaneous images. The switching and matrixing is
handled by the MX board.
Primary signal processing is handled by the four PR boards, which apply
gamma, contrast, brightness, color, sharpness and color temperature
adjustments. The projectors offer a gamma curve of 2.6 (recommended by DCI)
as well as gamma of 2.2 and 1.8. The LPD panel driver board operates with 12
bits of precision, for extremely natural images.
Four DC-SDI inputs can be combined to form a single, 4096 x 2160
image.
