Leader LT4400 Multiformat Video Generator
The 1U half-rack sized compact LT4400 Multiformat Video Generator applicable to both HD-SDI and SD-SDI systems outputs SDI video signals.
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.
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
The logomark up to 320 (dot) x 240 (line) in QVGA size can be superimposed at the 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 to each channel.
- Genlock Mode
This instrument can be locked by the NTSC/PAL black burst signals and 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 intermitted.
- 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 the 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. (Not available currently)
- 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 pixel) can be displayed.
