LT443D
Plug-In Modules Expand The Capability Of The
Multiformat Signal Generator
Multi Format Video Generator Main Frame
The LT443D Multiformat Video Generator Mainframe can be
used for multiformat digital broadcast systems. Various plug-in
modules enable the output of SDI signals (i.e. HDTV, SDTV),
sync signals, and analog signals. With these signals and
genlock functions, timing is settable in increments of frames,
lines, pixels or clock intervals. Users can customize the signal
generator as desired.
• ID Character Blinks
A 20-character ID display function is provided with selectable
blink on/off times to verify live program channel. A natural
picture pattern and logo can be superimposed with a
compact flash memory card (containing user bit map data)
installed to optional internal RAM.
• Various Patterns Include Stress Testing
With the SDI module installed, monoscope, natural picture,
and basic color patterns can be output. High-speed pattern
FEATURES
• Applicable To Multiformat HDTV
For the SDI signals, a 20 format HDTV module and a 525
line/625 line SDTV module are provided. The NTSC/PAL
composite analog video signal generator is available with the
10-field ID signal.
Since each module is capable of simultaneous outputs, a
multiformat system can be constructed to include both 74.25
MHz and 74.25/1.001 MHz outputs as the system grows.
MULTIFORMAT VIDEO GENERATOR
• Easy-to-use Sync Signals
For today's digital TV systems, BB (NTSC/PAL) and HDTV triIevel sync signals can be generated simultaneously. Timing is
set in intervals of frame, line, pixels or clock.
switching while scrolling at selectable directions and rates
stress tests systems for digital motion artifacts.
• Embedded Audio
Embedded audio in all SDI modules have capabilities to set
separate channel level, frequency, click ID, or silence. Setting
individual channel levels in 1 dB steps (0 to -60dBfs) allows
confirmation of system channel parade order. Choosing from
30 discrete frequencies allows confirmation of Lfe
encode/decoders.
• Digital Black Outputs
All digital black outputs for SDB and HDB modules can set the
raster to 0%/40%/50% flat field, embedded audio has same
capabilities as SDI outputs plus separately timeable in frame,
line, pixel or clock intervals.
• User-friendly Operability
Leader's traditional design and operability concepts are
reflected in this instrument. User-friendly operation includes
significantly reduced power-on initialization time required in a
highperformance instrument.

LT443D-GLA GENLOCK
LT443D-BL ANALOG BLACK
The LT443D-GLA Genlock Module has an external reference
loop through and a 3-system independent black signal
generator. External analog reference inputs can be
NTSC/PAL black burst, 14 formats of HDTV tri-level sync or
525p/625p sync. It can also accept black burst with a 10
field ID as per SMPTE 318M. Output sync signals can be
generated in 3-systems, as above, with independent timing.
Both genlock and black sync timing have a 5 frame settable
range for NTSC/PAL black burst and HDTV analog tri-level
sync signal inputs.
The LT443D-BL Analog Black Module can generate 14
formats of HDTV analog tri-level sync, 525p/625p analog
sync and NTSC/ PAL black burst signals. It consists of 3independent systems, each with 2-outputs, to provide simultaneous multiformat black sync signals. Each system can be
assigned an output format capable of independent output
timing. Also, it accepts a black signal with a 10 field ID
conforming to SMPTE 318M. In adjusting timing, the settable
range is a frame referenced to a 54 MHz clock for 525p/625p
analog sync signal and NTSC/PAL black burst signal, and a
frame by 74.25 MHz or 74.25 MHz clock for HDTV analog trilevel sync signal inputs.
