GENERATOR
Applicable to both HD-SDI and SD-SDI systems, 1U half-rack size
The compact, 1U half-rack sized, LT 4400 Multiformat Video
Generator is applicable to both HD-SDI and SD-SDI systems.
The various output capabilities are provided: color bar, SDI
check field test pattern, ID characters, logomark in QVGA
size, safety-area marker, superimposing embedded audio,
genlock mode to synchronize external reference signal, and
three independent analog black signal systems.
•Genlock mode
This instrument can be locked by a NTSC/PAL black burst
or HDTV tri-level sync signals for variable timing. The
NTSC/PAL black burst signals with field reference pulse
signal, and NTSC/PAL black burst signal with 10-field ID
are also applicable.
•Stay-in sync function
This function ensures the stable operation in genlock mode
even when the external reference signal is accidentally
intermitent.
•Analog black signal output
Three independent analog black signal output systems are
provided. The black burst signal with the same format as
the SDI output, or HDTV tri-level sync signal with the same
format of clock frequency can be selected for variable tim-
ing. The NTSC/PAL black burst signals with field reference
pulse signal, and NTSC black burst signal with 10-field ID
are also applicable.
•Pattern scroll (Simple motion picture mode)
The simple motion picture mode is provided to scroll the
pattern.
•Word clock output
The 48 kHz word clock output is provided to synchronize
the audio signal.
•Applicable to SNMP
The network system can easily be constructed since this
instrument supports SNMP. (Not available currently)
FEATURES
•Applicable to both HD-SDI and SD-SDI systems
Applicable to both HDTV (18 types of HDTV formats) and
SDTV (525i/59.94, 625i/50) systems. The HDTV or SDTV
can be selected.
•Superimposing ID characters
The ID characters can be superimposed at the arbitrary
position on the screen. The character blinks to indicate the
freeze status.
•Superimposing logomark
A logomark up to 320 (pixel) x 240 (line) in QVGA size can
be superimposed at an arbitrary position on the screen.
The logomark is converted from the bit map to four-grade
monochrome data.
•Safety-area marker
The 90 % and 80 % safety-area markers can be superim-
posed on the screen.
The 4:3 aspect-ratio marker can also be superimposed in
HDTV format.
•Superimposing embedded audio
The 16 channels of embedded audio signals (4 channels x
4 groups) can be superimposed. The frequency and level
can be respectively set for each channel.

■OPTION
•OP70:FULL SIZE LOGO Option
Applicable to the LOGO MARK of a full screen
The Logo Mark of full screen size (up to 1920 x 1080 pixels)
can be displayed.

Internal reference signal is used for operation. (INT mode)
AUTO (GO INTERNAL)
The EXT is automatically selected when the external reference signal is applied
to the GENLOCK input. The INT mode is automatically selected when the exter-
nal reference signal is removed.
MANUAL (GO INT)
The EXT mode is automatically selected when the external reference signal with
the same format specified to the GENLOCK input is applied after power is
turned on. The INT mode is automatically selected when no external reference
signal is applied to the GENLOCK input or signal format does not match the
specified format.
AUTO (STAYinSYNC)
The EXT mode is automatically selected when the external reference signal is
applied to the GENLOCK input after power is turned on.
If the external reference signal is accidentally removed during operation, the
instrument continues operation under the conditions immediately before the sig-
nal is removed since STAYinSYNC mode is provided.
After the external reference signal is recovered, the system is automatically
locked.
MANUAL (STAYinSYNC)
The EXT mode is automatically selected when the external reference signal with
the same format specified to the GENLOCK input is applied after power is turned
on. If the external reference signal is accidentally removed during operation, the
instrument continues operation under the conditions immediately before the signal
is removed since STAYinSYNC mode is provided.
The STAYinSYNC mode will be held until the reset operation is performed via the
front panel even after the external reference signal is recovered.
