No. 6 Video Format setting
Allows you to select video signal format.
OFF: NTSC ON: PAL
When both of No.5 NTSC Setup Level and No.6 Video Format are
set to ON, SECAM format is used.
* SECAM format is used for input and PAL format for output.
No. 7 DV setting
Allows you to specify the signal type for the device connected to
the DV terminal.
OFF: DVCAM ON: DV
No. 8 Video Sync Mode setting
Allows you to select whether to enable the PLL (phase-locked loop)
control or not. This switch is effective only for DV inputs.
OFF: External Sync ON: Internal Sync
Turn it ON when the color for analog output image does not come
out during DV input from OHCI card.
About Video Sync Mode
Video Sync Mode is effective only
for DV inputs.
When set to OFF:
The PLL operation is enabled to
synchronize frame period and
subcarrier period and such with
frame pulses of digital video
stream when outputting analog
video. When the incoming data
is within the lockable range,
frame-skip or hold will not ap-
pear in the output video.
When set to ON:
The PLL operation is disabled
to let the built-in circuit deter-
mine the frame period of ana-
log video to be output.
Since the frame period is not syn-
chronized with the input in this
mode, frame-skip and hold take
place. Even if the DV stream's
frame period is somewhat out of
sync with analog output, DV
Codec working as a frame-syn-
chronizer corrects the frame pe-
riod for the analog output.
