APPLICATION NOTES
NOTE 1
SERIAL CONTROL WITH SONY BVE
-
900 and BVE
-
9000 EDITORS
GENERAL COMMENTS
The
general
behavior of the APK
-
5003 V
as a source
machine is similar enough to that of
a
VTR
as
to be largely
transparent to the
operator
.
The
machine
'
s handling of time code
,
manual
transport
controls
,
and
source
selec
-
tion in
an
edit appears to be virtually the
same as
normal
VTR
operation
,
but
,
because
of limitations in
editor
architecture
,
certain edit types may require
Mixer
Setup changes
.
Operation
of the ATR with the editor does
not
utilize the
ATR
'
s CHASE , or
other higher order features such
as PREVIEW
,
EDIT or REVIEW .
The editor
simply
instructs the ATR to shuttle and stop
at specific points
.
VARIABLE SPEED PLAY
commands provide the
means
to
position the
ATR
to be
synchronous before the
IN
POINT
is
reached
.
Once
the correct synchronous operation is
attained , the ATR
is
commanded
to RESOLVE to
the external video
reference . The editor
is the sole controlling
entity
in
the process of the edit
sequence
.
CONNECTIONS AND SETUP
For
proper serial control with SONY
BVE
-
900
and
BVE
-
9000 Editors , the
following conditions must be met
.
The Editor must be connected to the APR
-
5003 V via
the
TRIBUTARY
serial
port
on
the
rear
panel of the
machine
.
(
See Figure 1
.
)
1
.
U
2 . The house
video reference
must be connected to either
one
of the
VIDEO
ports
on the rear
panel , and the
TERMINATION
switch must be set
as
follows :
a
.
Where the
APR
-
5003 V is
the video reference terminating link , the switch must be set to ON
.
b
.
Where the video reference is
daisy
-
chained to another device
,
the switch must be
set to
OFF .
3 . Storage Location 37 must be set to 1
,
thereby
selecting video
as
the resolving reference
.
The
correct tape speed must
be selected relative to the Time Code
on
tape , and
a
consistent Time Code type
must be used throughout
the
system
.
4
.
The Setup Menus for
VTR BLOCK
#
1 and
VTR
BLOCK # 2 must be in accordance with the data
given
in the
Recommended Menu
Setup for ATR usage
as
Player section
given later
in this document
.
5 .
It
should be noted that
,
at power
-
up
,
the Editor disables the machine
'
s
local control with its initial commands
.
This
can
be
re
-
established
by pressing
the LOCAL key
on
the Thmsport Control Panel
.
Furthermore , the serial
control capability
can
be
disengaged by deselecting
the
NETWORK
key
on
the
same
panel
.
METHODS OF USE
Stand Alone
,
Audio
Only
,
Source Edits
O
In
this application
,
the
ATR
operates
as a
stand
-
alone audio
source
, and programming an edit
does not differ
from normal
VTR
operation
.
Specifically
,
an
audio only
Cut
or
Dissolve from the ATR
is
programmed
in the
same
manner as
it
would be for
a
video
source
.
The ATR
is not
linked with any other
Player
.
Time Code match frames
are
listed in the
same manner as
with
VTR
applications
.
Edit
data for the
ATR
is preserved in the
EDL
.
