Multiformat Video Generator Main Frame
The LT443D is ideal where
multiformat digital broadcast
systems are the norm. With
plug-and-play modules
available for HD-SDI and
SD-SDI generators, genlock,
analog black, genlock, digital audio, analog audio and analog composite NTSC/PAL formats, users can customize this
signal generator as desired. Create custom systems that simultaneously output multiple formats. The mainframe/ front
panel includes power supply and ethernet control. Four plug-in slots allow for addition of generators with embedded
digital audio, genlock module and a sync generator for tri-level and or black burst outputs. Plug and play operation
ensures each of the modules are automatically recognized.
Optional Plug-in Modules
◆ The LT 443D-HD (Mfr # LT443DHD • B&H # LELT443DHD) and LT443D-SD (Mfr # LT443DSD • B&H # LELT443DSD)
SDI generators include monoscope, colorbars, ramps, pathological and still picture test patterns
with simple scrolling and high-speed pattern switching for stress testing MPEG encoded
systems for compression artifacts. Digital audio in the SDI generators is selectively embedded
as two groups of four channels. Each channel is separately configurable for frequency, level
and click ID.
◆ The LT 443D-HDB (Mfr # LT443DHDB • B&H # LELT443DHDB) and LT443D-SDB (Mfr # LT443DSDB • B&H #
LELT443DSDB)
are the same as above, plus offer the option of 2 separate blackburst outputs.
◆ The LT 443D-GL genlock module has a loop through and also outputs 3 separately configurable
and timeable trilevel or bi-level sync outputs. Timing is adjustable in increments of samples,
lines or frames up to ±5 frames maximum
. (Mfr # LT443DGLA • B&H # LELT443DGLA)
◆
The LT443D-BL sync module outputs three separately configurable and timeable pairs of black
burst or tri-level sync signals to be advanced or delayed up to five frames max. Timing can be
incremented in frames, lines or samples.
(Mfr # LT443DBL • B&H # LELT443DBL)
◆
LT443D-DA module outputs four pairs of AES/EBU digital audio. (Mfr # LT443DDA • B&H # LELT443DDA)
◆
The LT 443D-CS module outputs analog composite NTSC/PAL formats.
◆ The LT 443D-AA is an analog audio generator with low distortion convenient for generating
and distributing system reference levels.
(Mfr # LT443DAA • B&H # LELT443DAA)
◆
LT-443DOP70 is a Natural Picture Module for the LT-443D. Natural Picture data can be loaded
into the LT-443D via the Memory Card Slot; it then can be accessed, output and displayed
through video outputs of the LT-443D.
(Mfr # LT443DOP70 • B&H # LELT443DOP70)
◆
LT-443DCS is a composite test signal module producing 23 test patterns, NTSC/PAL black burst
and H and V Drive for system timing. It fits into the LT-443D Main Frame deriving power and
control for signal generation.
(Mfr# LT443DCS B&H# LELT443DCS)
FEATURES
◆ 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.
◆ For today's digital TV systems, BB (NTSC/PAL)
and HDTV tri-Ievel sync signals can be
generated simultaneously. Timing is set in
intervals of frame, line, pixels or clock.
◆ A 20-character ID display function is pro-
vided with selectable blink on/off times to
verify live program channel. A natural picture
pattern and logo can be superimposed with
a compact flash card (containing user bit
map data) installed to optional internal RAM.
◆ With the SDI module installed, monoscope,
natural picture, and basic color patterns can
be output. High-speed pattern switching
while scrolling at selectable directions and
rates stress tests systems for digital motion
artifacts.
◆ All digital black outputs for SDB and HDB
modules can set the raster to 0%/40%/50%
flat field, embedded audio has same capabil-
ities as SDI outputs plus separately timeable
in frame, line, pixel or clock intervals.
◆ User-friendly operation includes significantly
reduced power-on initialization time
required in a high-performance instrument.
◆ 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.
