Y/C Delay
Adjust the horizontal Chroma timing in relation to Luma. It is suggested that you use the Y/C-
delay calibration image from the Special Tests section of Advanced AVIA, to calibrate the Y/C-
delay. The C
B
and C
R
channels are adjusted separately.
MENU → IN → CONFIG → ADJ → YC-DLY → […, †, ˆ, ‡] OK
Sharpness
This command is used to adjust the sharpness for all inputs It is generally best to leave this at
the factory default setting. The command format is:
MENU → IN → CONFIG → ADJ → SHARP → […, †] OK
Input Level
This command specifies if an analog input has a black pedestal, and if DVI inputs use video levels
or PC levels. I you are unsure, it is better to leave these at 0 IRE for analog, or PC level for DVI-
D. The analog command format is:
MENU → IN → CONFIG → ADJ → LEVL → (7.5 IRE, 0 IRE) OK
The DVI input command format is:
MENU → IN → CONFIG → ADJ → LEVL → (VIDEO, PC) OK
Input Name
Each input configuration memory can be named. Follow the on-screen directions. The … and †
arrows select which input to change and then which character to change. The ‡ and ˆ arrows
change the selected character. The command format is:
MENU → IN → CONFIG → NAME
Select Deinterlacing Mode
The default deinterlacing mode, for both SD and HD material, is to automatically detect film or
video source material and deinterlace accordingly. Since this can never be a perfect detection,
the Lumagen processor allows the user to force deinterlacing to assume the source material is
video. For SD material the choices are AUTO1, AUTO2, Video and FILM. For HD the choices are
AUTO1, AUTO2, VIDPP and VIDNC. The AUTO2 mode is similar to AUTO1 but will more quickly
switch to video mode and can be better suited if the source tends to have more video material
than film.
The HD VIDPP mode uses a “per-pixel” motion adaptive deinterlacing algorithm (as used for SD
deinterlacing), and the VIDNC uses a scaling deinterlacing method. While the VIDPP mode
generally provides the best image, the Lumagen will not comb in VIDNC mode, and so VIDNC is
sometimes preferable.
The deinterlacing mode command format for SD inputs is:
MENU
→ IN→ CONFIG→ CNTRL→ DEINT→ MODE→(AUTO1,AUTO2,VIDEO,FILM) 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→ (AUTO1,AUTO2,VIDPP,VIDNC) OK
