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.

• 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 superimposed 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.
• Genlock mode
  This instrument can be locked by a NTSC/PAL black burst or HDTV tri-level sync signal for variable the 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 timing.
  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.
• OPTION
  
  • OP 70: FULL SIZE LOGO Option (factory option)
    Applicable to the LOGO MARK of a full screen.
    The Logo Mark of ull screen size (up to 1920 x 1080 pixel) can be displayed.
  • LT 4400SER01: LIP SYNC Option(factory option)
    By adding the LT 4400SER01 option to the LT 4400, you can accurately meseure the lip sync of the video and audio in an SDI signal. To measure the lip sync, use Leader's LV 5800.
