Chapter 2 Total System 34HDC-900/950/930 Series Product Information Manual
2-7-2 Setting the System Format using
HDCU-950
For a system using the HDCU-950, the output signal
format must be set.
Normally the Multi-Format is set from the RM/MSU or a
device that is connected externally. However, it can
also be set by the switches on the AT-149 board or FC-
88 (HKCU-953) board.
(1) Setting the HD-SDI output
Set the output signal format as the HD-SDI signal. At
the same time, this setting becomes the shooting
mode of the camera.
1. Set the field frequency coefficient.
Setup switch : S420 on the AT-149 board (Factory
setting : REMOTE)
1.001 : Set the field frequency to 1/1.001 times
(Set the field frequency to 1.001 when
using NTSC (525/60) signal in the SD
system.)
1.000 : Set the field frequency to 1 time. (Set the
field frequency to 1.000 when using PAL
(625/50) signal in the SD system.)
REMOTE : Set it with RM/MSU, etc., that is
connected outside.
2. Set the field frequency.
Setup switch: S418 on the AT-149 board (Factory
setting: 60 V)
60 V : When the FC-88 board (HKCU-953) is not
used but the NTSC (525/60) signal is used in
the SD system.
50 V : When the FC-88 board (HKCU-953) is not
used but the PAL (625/50) signal is used in
the SD system.
48 V : At present, this function is not supported.
3. Set the shooting mode of the camera.
Setup switch : S419 on the AT-149 board (Factory
setting : INTR)
INTR : When shooting with interlacing system.
PROG : When shooting with progressive (PsF)
system.
540P : When shooting with 540-60P system. (At
present, this function is not supported.)
Note:
If you select a format of 48i (48 field interlace) or
another format that is not supported by the HDCU-950,
the setting causes an error and the indicators (D201 to
D205) on the AT-149 board will flash.
(2) Setting the SD signal output
When S420 on the AT-149 board is set to a position
other than REMOTE, set the SD signal output to NTSC
(525/60) or PAL (625/50).
Setup switch : S423-1 on the AT-149 board (Factory
setting : OFF)
ON : PAL (625/50)
OFF : NTSC (525/60)
(3) Setting the frame conversion (when the HKCU-
953 is installed)
When the shooting mode of the camera is set to 24PsF,
set the HD-SDI output signal format from the HKCU-
953.
Setup switch : S2 on the FC-88 board (Factory
setting: OFF)
ON : When the shooting mode of the camera is set
to 24PsF, the frame frequency conversion is
implemented.
OFF :The frame frequency is not converted. The
same signal as the main HD-SDI signal is
output.
Note:
The setting of the frame conversion frequency must
follow the set format of the SD signal output.
When S423-1 on the AT-149 board is set to OFF
(NTSC), the frame frequency is converted to 60i (30
Hz).
When S423-1 on the AT-149 board is set to ON (PAL),
the frame frequency is converted to 50i (25 Hz).
