SDTI interface
Digital data input/output operations using the SDTI
format (compressed digital interface) are enabled by
installing the AJ-YAC930G SDTI board (optional
accessory) in this unit.

SDTI (Serial Data Transport Interface) complies with
the SMPTE 305M standard.
The data stream format transferred via the SDTI
complies with the SMPTE 321M standard.
Precautions to observe when using the
SDTI signals
OThe unit can record only if the SDTI input signals
are 1atransfer signals in the DVCPRO50 or
DVCPRO format selected by setup menu No. 012
(SYS FORMAT).
However, when playback signals other than normal
1aplayback signals have been input, recorded
and EE picture and sound are not guaranteed.
OEditing operations can be performed only when all
the video and audio signals as well as the time
codes in the SDTI input signals are regular data
based on the DVCPRO50 or DVCPRO format
selected by setup menu No. 012 (SYS FORMAT).
OCUE signals are not transferred by the SDTI
interface.
OSDTI dubbing is not possible from tapes recorded
using the DV or DVCAM format. 
Use SDI when dubbing tapes recorded in the DV or
DVCAM format.
OWhen playing back a DV or DVCAM format tape,
DV compressed signals (Compliant with IEC61834-
2.) serve as the SDTI output.
OThe video and audio signals in the SDTI output
signals cannot be adjusted.
ODuring SLOW/STILL playback, the unprocessed
video and audio signals are output as the SDTI
output.
When these video and audio signals are to be
monitored using another device, they may differ
from the video and audio signals played back by
this unit.
