1·6. OPTIONAL ADAPTOR AND ACCESSORIES
1-6·1. Dynamic tracking memory board BK-2001
When
combining
the BVT-2000 with
the
BVH-1
000 for
dynamic
tracking
playback
(guard band
noise-less playback),
it
is
necessary to
plug
one optional memory board (same
as
MAIN MEMORY board
of
BVT-2000)
into
slot
number
8 (16).
Whereas
the correction
range
is
4
Hp-p
with
one
MAIN
MEMORY
board, two
boards
expand
this
range
to
12 Hp-p. It
is also
po
ssible
to yield proper
pictures with dynamic
tracking
p
layback.
Using
the
MEMOR
Y
boards is
effective when
playing
back a
tape
containing a great
deal
of jitter
(for
example, a
tape
which
has
been
recorded on
a portable
U-matic
while
on the
move).
The
vertical
phase
shift
which
is produced
with
a
correction
range of
4
Hp·p
can
be
eliminated.
1-6-2. Heterodyne color VTR color processor BK-2003
Use
this
adapter
when converting
the playback
signals
of a
heterodyne
color
VTR
(V0-2860)
without
a subcarrier
input
connector
into
standard
broadcasting
signals~
or
when
it is not
possible
to
return the
subcarrier signal
to the
VTR
from the time
base corrector
with
microcircuits
even
when a
VTR,
which
is
provided
with
a
subcarrier
input
connector, is
being
employed
.
The
adapter
is
configured
as
a
single
printed
circuit
board
(called
HET
ERODYNE COLOR),
and it
is inserted
into
the
positio
n
marked
by
slot
number 12
on
the time
base
corrector.
f
or
the
above instances,
set
the DIRECT/
PROCESS switch on
the
board
to
PROCESS, and for
all
other
instances,
set the
switch
to
DIRECT.
