The deinterlacing mode command format for SD inputs is:
MENU → IN → CONFIG → CNTRL → DEINT → MODE →
( AUTO, VIDEO ) OK
For HD inputs, the mode for SD and HD sources are selected independently. The SD
portion is the same as for SD only inputs. The HD selection command is:
MENU → IN → CONFIG → CNTRL → DEINT → MODE →
(
AUTO, VIDPP, VIDNC
)
OK
Flip Input Field
Some source devices do not follow conventions for the order of video fields. This can be
seen as excessive combing in the video. While generally not required, this command
allows the input fields to be swapped so the images can be properly deinterlaced. The
command format is:
MENU → IN → CONFIG → CNTRL → DEINT → FIELD →
(
NORM, FLIP
)
OK
Genlock
Genlock is the ability to exactly lock the output rate to the input rate, or to a multiple of
the input rate.
For a typical setup with an NTSC source (nominally 59.94 Hz) and outputting a 59.94 Hz
rate to the display, the clocks of the NTSC source and the Lumagen will never match
exactly. Because of this very slight mismatch, there will be a dropped (or doubled) frame
once every few minutes. When genlock is enabled, the Lumagen output clock is varied
slightly to keep its output rate locked to the input rate. This avoids any dropped/doubled
frames. This may not be observable by most users, but genlock corrects this issue for
users who are sensitive to it. Another benefit of using genlock is that it does slightly
reduce the video delay (aka lipsync delay) going through the video processor. It also
makes the delay constant through the Lumagen. When genlock is off, the delay varies
over time by about one field time.
To check the genlock status, press the OK button on the remote several times until the
genlock status is visible. This must be done when no onscreen menu is present. Possible
states are OFF, DISABLED, LOCKING and LOCKED. Genlock is disabled if the output
is not an appropriate multiple of the input. For NTSC, genlock is able to lock output rates
of 24sF (actually 23.976), 47.95hz, 59.94, or 71.93 Hz. For PAL sources, 50 Hz and 75
Hz outputs can achieve lock.
Genlock can be enabled/disabled on a per-input memory basis. The command format is:
MENU → IN → CONFIG → CNTRL → GENLOCK →
(
YES, NO
)
OK
DVI input HDCP Capability Setting
Some DVI sources limit functionality when driving HDCP capable devices, such as
disabling their analog outputs, even though they do not require HDCP capability. This
command can disable reporting HDCP capability for the current DVI input memory.
Note: When HDCP capability is disabled, HDCP encrypted sources are not displayed.
MENU → IN → CONFIG → DVI → HDCP →
( YES, NO ) OK
