Chapter 1 Overview
Compact design
Since the unit is as compact as a standard desktop
personal computer in size, it is ideal for personal use
on your desktop. In addition, front loading of both S
and L cassettes is standard.
Menu-based setup
Initial settings for the unit’s operation, interfaces with
connected equipment, and so on, can be made by means
of menu operations on the front panel of the unit.
A wide range of status indicators
A large-sized fluorescent display is provided to show
numerical values including audio level, time code, user
bits, error messages, and setup menu information in
addition to the current settings and operating status of
this unit.
Minimal maintenance
The unit is designed to need minimal maintenance, and
requires no daily maintenance or checks.
A drum and other components have reduced
maintenance costs.
Vertical installation
This unit can be installed vertically using the supplied
vertical installation stands. The unit can be installed
either vertically or horizontally, saving space on your
desktop.
1) (DV) output (available only when an
HKJ-101 i.LINK 1) Interface Board is
installed)
When an optional HKJ-101 i.LINK Interface Board is
installed, this unit can output digital video/audio
signals in DV format compatible with i.LINK from the
DV output connector.
2-3 pulldown sequence (J-H3 only)
If you set the system frequency to 23.98PD, you can
output 59.94i video signals while a tape recorded in
23.98PsF is being played back. The following is the
2-3 pulldown sequence.
Note
The 2-3 pulldown sequence process is guaranteed only
during playback in PLAY mode.
Time code multiplexed to pull down signal output
• The value of the time code multiplexed to pull down
HD SDI output signal is determined by the time code
preset using 24F TC A-FRAME SELECT, extended
menu item 623 and 30F TC A-FRAME SELECT,
extended menu item 624, and then converted from
23.98-frame into 29.97-frame time code.
• Time code data of the user’s bits area is not output
when the 23.98PD system functions. The time code
value before conversion (23.98-frame mode) and
sequence information of conversion contained in
user’s bits data are multiplexed to the HD SDI output
signal. The following four bits are used for the
sequence information to display 0 to 9 repeatedly.
MSB: The first bit of the tens digit of the hour
The second bit of the tens digit of the hour
The first bit of the tens digit of the minute
LSB: The first bit of the tens digit of the second
When the sequence information is masked, the
remaining contents of user’s bits data are the same as
the time code value before conversion (23.98-frame
mode).
Note
Since user’s bits data multiplexed to the down-
converted output signal are updated frame by frame,
23.98-frame time code and sequence information of
the down-converted output signal differs from those
multiplexed to the HD output signal.
