Leader LT4610 3G/HD/SD Multi-Format Video Sync Generator

The LT4610 is a 1RU rack size Sync Generator that supports the triple-rate SDI (3G/HD/SD) format. The unit is equipped with a redundant power supply, which is very valuable if power is lost to the main supply. In addition to test pattern output including color bars and SDI check fields, the LT4610 is equipped with numerous features such as ID characters, QVGA logo marks, safety area markers, audio word-clock, lip-sync, genlock function for external reference signals, and six analog black signals.

Test patterns available from the LT4610 include 100% and 75% color bars, multi-format color bars and SDI check fields with user-selectable scrolling in eight combinations of up/down/left/right. Scrolling speed is user adjustable. Y/G, Cb/B, Cr/R components can be turned on or off independently for each output channel.

Features:

• QVGA (320 pixel x 240 line) 24-bit full color bitmap logos can be transferred into the generator via USB memory and added to any test pattern.
• LT4610 can also generate IDs of up to 20 characters for placement at any operator-assigned screen position. ID size is selectable between 32 x 32, 64 x 64, 128 x 128 and 256 x 256 pixel sizes at 100% or 75% intensity, continuous or blinking. IDs can be scrolled to the left or right.
• Safety area markers can be generated to show safe-action area (90%), safe title area (80%) and/or 4:3 aspect ratio. ID characters, logo mark, safe area markers and test pattern can be displayed individually, sequentially or simultaneously.
• Audio test generation capabilities include silence, 400 Hz, 800 Hz, and 1 kHz at -60 to 0 dBFS in 1dBFS steps, assignable across up to 16 channels for 3G-A/HD/SD and 32 channels for 3G-B. Audio sampling resolution can be selected from 20 or 24 bit at 48 kHz and synchronized with the video signal. Audio clicks can be generated between 1 and 4 seconds or disabled.
• Test patterns with synchronized audio can be generated for lip sync testing. The audio click setting is disabled in this mode. SDI output 1 is synchronized to the AES/EBU output. When using Leader's LV5770A waveform monitor you can accurately measure the lip sync of SDI video and audio signals.
• LT4610 has a genlock input and can be synchronized with NTSC/PAL black burst or HD tri-level sync signals. Six independent analog black burst reference signals are provided, which can be changed to tri-level sync. A 48 kHz word clock output and 48 kHz AES/EBU output are also provided for synchronizing audio signals.
• Standard support for SNMP via Ethernet makes it easy to integrate the LT4610 into a network environment. Alarms are generated with SNMP and displayed on the front panel when errors do occur.
• Redundant power supply with fast automatic switchover is standard.
