Figure 1-1. Model KX60 Television Titling Unit

SECTION | — General Description
1.1 GENERAL
The K60 Series Television Titling Unit provides a means of adding electronically-generated
alpha-numeric titles to picture video in standard television systems. Information is entered directly
onto the screen from the typewriter-like keyboard of the K60.
By using the K60, alphanumerics can be generated for display in three ways: 1) by passing a
video signal through it, 2) by driving with sync as a source of video for display of alphanumerics alone,
and 3) by mixing with picture in external equipment (such as mixers, special effects generators, etc.)
The K60 character alphabet contains 64 letters, numerals and symbols, any of which may be
placed at any of up to 512 discrete positions on the television screen. Memory for four such pages is
provided internally. A page of characters is formatted into sixteen lines of 32 characters. Control
functions allow entry of information at any location on the page.
An independent video channel allows composition and editing on any one of the four pages
provided while the contents of that or another page are being displayed with picture.
In addition the the basic K60 model, the KS60 provides internal sync generation (switch
selectable) and the K X60 provides internal sync, timed page advance, and a title/crawl mode of oper-
ation. With the title/crawl mode the K60 allows insertion of as many as 32 independent subtitles, or
one long continuously moving message in the lower third of the picture area.
IS IS THE K6@ FONT.
E KNOX K6@ IS ORGANIZED INTO
16 LINES OF 32 CHARACTER LINE
LENGTH.
THE K6@ CHARACTER ALPHABET HAS
64 ELEMENTS, ANY OF WHICH CAN BE
PLACED AT ANY OF UP TO Ste
DISCRETE POSITIONS ON THE TV
SCREEN. MEMORY FOR FOUR SUCH
PAGES IS PROVIDED INTERNALLY.

SECTION 2 — Installation
21 AC POWER
The
K60
should
be
connected
into
standard
3-wire
grounded
electrical
systems
(normally
120
V
60
Hz
but
available
in
220
V
50
Hz).
DO
NOT
USE
3-wire
to
2-wire
adaptors.
Loss
of
system
ground
could
cause
an
electrical
shock
hazard,
and
could
do
extensive
damage
to
the
K60.
mak VIDEO INPUTS
These are the inputs to which program page titles will be added. Connect composite video-
sync, 1.0 volts p-p (EIA RS170, RS330, EIA-J, or similar 525-line, 60 fields/sec standards*), to one of
the input video BNC connectors at the rear of the unit. A second input BNC is available for looping the
original signal to other equipment. If no looping is required, the second BNC input should be terminated
with a 75-ohm resistive load.
The K60 may also be driven from composite sync-only (nominally 4.0 volts, p-p). When
the K60 is driven with 4 volt sync, the Program channel will not have a usable output. To regain use of
Program channel, drive the K60 through a 10:1 pad while properly terminating the sync signal externally.
When using the optional internal sync (see section 2.4) the sync is padded internally.
2.3 VIDEO OUTPUTS
PREVIEW
—
A
composite
signal
made
up
of
sync
regenerated
from
the
input
drive
signal
and
video
dots
representing
the
information
on
the Preview
page
selected.
This
output
would
normally
be
connected
to
a
local
video
monitor
through
75
ohm
cable
for
composition
and
editing.
PROGRAM
—
A
composite
signal
made
up
of
the
video
input
plus
video
dots
representing
the
information
on
the
Program
page
selected.
This
is
the
Line
output,
and
is
meant
to
drive
monitors,
video
tape
recorders,
modulators,
or
video
distribution
systems
through
75
ohm
cable.
Character
level
is
adjusted
to
approximately
1.0
volts.
For
purposes
of
mixing
with
input
picture,
the
input
signal
is
assumed
to
be
composed
of
approximately
0.3
V
sync
and
0.7
volts
maximum
video.
When
the
K60
is
driven
with
sync
directly,
no
Program
output
is
available
(see
Video
Inputs).

2.4 INTERNAL SYNC OPTION (KS60 or K X60)
If fitted with the Internal Syne Option, the K60 has a toggle switch on the rear panel near the
BNC connectors marked INT-EXT. In the EXT position the K60 requires video or sync drive. In the
INT position a circuit inside the K60 generates composite syne similar to RS170 standards. Both Pre-
view and Program outputs appear as white characters over a black background.
