LEADER LT4400 User Manual

MULTI FORMAT VIDEO 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 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)

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 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.

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 external 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 signal 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.
