SMPTE/EBU Time Code
SMPTE is an acronym for the Society of Motion
Picture and Television Engineers. The SMPTE Time
Code (C98.12: time and control code for video and
audio
tape
for
525/30
television
system)
was
defined
in
1970, and it is now accepted as a universal standard.
This reference is to an 80-bit digital code developed
by SMPTE and used to designate the exact location in
hours, minutes, seconds and frames (24 frames/sec. for
film or 30 frames/sec. for video) on a film, video tape, or
audio tape. Suitable equipment can synchronize ("lock
up”) two or more machines by using the SMPTE time
code recorded on each.
SMPTE. European Standard, that refers to 25 frames
per second, states the EBU (abbrev. for European Broad-
casting Union) time code when it is especially necessary
to distinguish from the USA Standard with 30 frames
per second.
A time code generator is used to record SMPTE code
onto one track of the tape. A time code controller can
then read the code from two or more tape machines, and
by also servo-controlling the reel motors of those ma-
chines, bring them to specifiec cue points. A time code
synchronizer further controls the capstan motors to
keep both of the tape machines running synchronously.
These techniques can be used to obtain more tracks for
recording (two or more audio machines “locked up” to-
gether), to mix audio signals in sync with video or film
images, to make complex edits by transferring material
from one or more audio machines to another, and so
forth.
Connecting a Synchronizer to the TASCAM TSR°8 -
Connection between the ES-50 synchronizer/ES-51
edit controller and the TSR-8 is a plug-and-go pro-
position. Pre-wired interface cables needed are available
from TASCAM.
The TASCAM TSR-8 provides signals to the synchro-
nizer (via the ACCESSORY “1” connector) which
indicate its speed, the direction of the tape travel, and a
reference power supply. Also, tally signals indicating the
TSR-8’s mode (PLAY, F.FWD, REW, STOP) are given
to the synchronizer so it knows the current transport
status. Inputs on the same ACCESSORY ‘‘1”’ connector
are provided for status commands from the synchronizer
(PLAY, F.FWD, REW, STOP, REC, LIFTER CONT).
Also, there is an input for a capstan drive reference
frequency signal from the synchronizer so that the
actual record/play speed can be varied to maintain
synchronization. For pin assignment see page 12.
The TSR-8 will also operate satisfactorily with a
variety of other manufacturers’ synchronizer/controllers.
The manual for these products should provide you with
enough interface information for use with the TASCAM
tape machines. Or else, consult the synchronizer
manufacturer for further details on interfacing.

The

operates
to
its
full
potential
when
in-
terfaced
with
the
MIDiiZER,
an
intelligent,

ver-
satile
serial
synchronizer,
which
provides
a
link
between
SMPTE/EBU

audio/video
production
and

It
shifts
between

and

the
