DESKTOP CONTROL PANEL OPERATION
Revision 1.5
Page 4-9
Select 444HD when you want the HD9690-444 to always operate with 4:4:4 HDSDI incoming video. You
must connect a valid 4:4:4 video signal to the Link A and Link B input BNC connectors. The 444 Mode
menu item must be set to match the colour space of the incoming video.
Select
422HD when you want the HD9690-444 to always operate with 4:2:2 HDSDI incoming video. You
must connect a valid 4:2:2 video signal to the Link A BNC connectors. (Any signal connected to the Link B
BNC is ignored) The
444 Mode menu item is ignored in this mode and the graticule generator will be
configured for YCbCr colour processing.
4.2.12. Selecting the 4:4:4 Colour Space (Model HD9690-444 only)
444 Mode ycbcr rgb fsfull fsnorm
This menu item selects the colour processing that will be applied on the incoming video. It should be set
to match the colour space of incoming 4:4:4 video. This menu item is not not visible with 4:2:2 input video
formats. See Table 3-1 for details of the four colour processing modes and Table 3-2 for the colour palette
information.
Select
ycbcr when the incoming video is in the 10 bit 4:4:4 YCbCr format. In the ycbcr mode, the RGB to
YCrCb colour transformation for the 4:2:2 MON output will be disabled, the YCrCb to RGB colour
transformation for the DVI output will be enabled and graticule objects will have normal colour values.
Select
rgb when the incoming video is in the 10 bit 4:4:4 RGB format compliant with SMPTE 274M or
SMPTE 296M and the 4:2:2 output is to be in the normal 10 bit YCbCr format. Both the RGB and YCrCb
video has the three components scaled such that the extreme values are code words 040
h
(64) and 3AC
h
(940) in a 10-bit representation. In the rgb mode, the RGB to YCrCb colour transformation for the 4:2:2
MON output will be enabled, the YCrCb to RGB colour transformation for the DVI output will be disabled
and graticule objects will have normal colour values.
Select
fsfull when the incoming video is in the extended range 10 bit 4:4:4 FSRGB format and the 4:2:2
output is to be in the FSYCbCr format. Both the FSRGB and FSYCbCr video has the three components
scaled such that the extreme values are code words 04
h
(4) and 3FB
h
(1019) in a 10-bit representation. In
the fsfs mode, the FSRGB to FSYCrCb colour transformation for the 4:2:2 MON output will be enabled,
the YCrCb to RGB colour transformation for the DVI output will be disabled and graticule objects will have
full scale colour values.
Select
fsnorm when the incoming video is in the extended range 10 bit 4:4:4 FSRGB format and the 4:2:2
output is to be in the normal YCbCr format. The FSRGB video has its three components scaled such that
the extreme values are code words 04
h
(4) and 3FB
h
(1019) in a 10-bit representation. The YCrCb video
has the three components scaled such that the extreme values are code words 040
h
(64) and 3AC
h
(940)
in a 10-bit representation. In the fsrgb mode, the FSRGB to YCrCb colour transformation for the 4:2:2
MON output will be enabled, the FSRGB to RGB colour transformation for the DVI output will be enabled
and graticule objects will have full scale colour values.
