DESKTOP CONTROL PANEL OPERATION

OSD Posn =

Bot l
Bot r
center
This menu item allows the user to set the area on the screen where the on-screen display will be shown.
Turn the right shaft encoder to move the display to one of 5 positions on the screen.
4.2.9. Selecting the SMPTE Safe Area Specification
Safe Area = 2046
RP218
SMPTE has recently published a new safe area specification in SMTPE ST 2046-1 based on fixed pixel
matrix displays and are significantly larger than previously specified in RP218, The safe areas specified in
RP218 are a legacy of past practice and are based on the limitations of CRT-based displays. This menu
item allows the user to set whether the SMPTE ST 2046 or RP218 safe area specifications will be used for
the factory presets
4.2.10. Operating the HD9690 in Auto Video Standard Mode
The HD9690 operates in an auto video standard mode and will attempt to detect the video standard of the
incoming video and change the current video standard to match. When the incoming video does not
match the current standard, the Graticule Generator will switch to the new video standard after
approximately 5 seconds. This delay prevents random standards switches that otherwise may occur
between some of the video formats. The new video standard will be displayed on the front panel. Video
standards changes will not occur while the Graticule Generator is in the
Setup
mode, or while the on
screen objects are being moved using the shaft encoder knobs.
Most of the supported standards can be detected, but there are some exceptions.
•
The standards 1080I and 1080PSF are the same as far as the Graticule Generator is concerned.
When the video input is in either of these standards the Graticule generator will display the standard as
1080I
4.2.11. Selecting the Video Type (Model HD9690-444 only)
Vid Type= Auto
444 HD
422 HD
This menu item selects the video type in use.
Select
AUTO
when you want the HD9690-444 to automatically detect the video type (444 HDSDI or 422
HDSDI) from the incoming video. The HD9690-444 will attempt to detect whether the incoming video is
single link 4:2:2 or dual link 4:4:4 and change its internal colour space processing to match. When both
Link A and Link B input BNCs have incoming video in the same standard the HD9690-444 will assume
that the input video type is 4:4:4 dual link video conforming to the SMPTE ST 372 standard and the front
panel 444 LED will be ON. The
444 Mode
menu item must be set to match the colour space of the
incoming video. (See section 4.2.12) When only the Link A input BNC has incoming video, the HD9690-
444 will assume that the input video type is 4:2:2 YCbCr conforming to the SMPTE ST 292-1 standard.
The
444 Mode
menu item is ignored in this mode and the graticule generator will be configured for YCbCr
colour processing.
