      產品詳細介紹Product Introduction

      The LT4611 is a 1U full rack size sync generator that can operate in synchronization with GPS, BDS, PTP, CW, and internal reference signals, as well as Genlock that supports external analog video synchronization signals.
      It supports analog video sync signals, AES / EBU digital audio output, word clock, and time code, and also supports 3G / HD / SD-SDI output and 12G-SDI output compatible with 4K and 8K.
      In addition, it supports the PTP grand master function and PTP slave function, and can manage the optimum synchronization system according to the system.
      The genlock function is equipped with a STAY IN SYNC function that retains the phase when an abnormality occurs in the input analog video synchronization signal, and the power supply unit performs redundant operation, enabling highly reliable system construction.
      LT4611 has slimmed down the standard functions from the standard specifications of the LT4610, the SDI output function, audio output function, and three of the six analog sync signal output systems to be prepared as optional product. Functions can be added as needed, allowing you to configure the system with specifications that meet your objectives.

      Features

      • Genlock Function
        Various output signals can be synchronized by applying NTSC/PAL black burst signals, which are analog video sync signals, and HDTV tri-level sync signals.
        NTSC/PAL black burst signal with field reference pulse and NTSC black burst signal with 10 field IDs are also supported.
      • Stay-in-Sync and Slow Lock Functions
        A Stay-in-Sync function is available in case errors occur at the genlock input. In addition, a slow lock function is available to reduce the shock that occurs when genlock is performed again based on stay-in-sync. This makes it possible to construct an extremely reliable synchronization system.
      • Analog Video Sync Signal Output
        Three analog video sync signals can be output (up to six using an option). The phase of each output can be adjusted independently.
        NTSC/PAL black burst signal with field reference pulse and NTSC black burst signal with 10 field IDs are also supported.
      • GPS/BDS Synchronization
        GNSS antenna can be connected to generate and output signals by locking to the frequency and clock obtained from the GPS or BDS.
      • PTP
        PTP synchronization corresponds to the grandmaster and slave functions.
        You can choose reference signal from PTP, GPS, analog BB or internal.
      • Time Code I/O
        The ATC (LTC) can be embedded in LTC outputs from internal time, GPS, LTC, and VITC time information, and SDI signal outputs, or VITC in analog video synchronous signal outputs.
      • Triple-rate SDI Ready
        SDI signal output supports 3G-SDI (level A and level B), HD-SDI (including dual link), and SD-SDI. There are two independent outputs of SDI signal at output terminals. The pattern and phase can be set separately for each. (However, only a single output is available for 3G-SDI level B and HD dual link.)
      • Lip Sync Patterns
        This option can output lip sync patterns in which the video and audio are synchronized. In combination with a waveform monitor that features a lip sync function, such as the Leader’s LV5600, it is possible to measure the offset between the video and audio in SDI signal transmissions.
      • 12G-SDI Support
        Four output connectors can be added to support 12G-SDI, 3G-SDI (level A, level B) and HD-SDI (including dual links).
        In addition, it corresponds to the 8K video signal by adding 8K software option.
      • Audio Embedding
        The LT 4611 can embed 32 channels (stream 1, stream 2, 4 channels each × 4 groups) of audio signals for 3G-SDI level B and 16 channels (4 channels × 4 groups) of audio signals for 3G-SDI level A, HD-SDI, and SD-HDI. The frequency, level, and the click can be set for each channel.
      • AES/EBU Signal Output
        The LT 4611 can output a 48 kHz AES/EBU signal synchronized with the video signals. It is also equipped with a muted AES/EBU signal output.
      • Word-Clock Signal Output
        The LT 4611 can output a 48 kHz word-clock signal synchronized with video signals.
      • Real Time Clock
        The real time clock is backed up by a battery. There is no need to reset the clock even when the power is turned off and on.
      • Ethernet
        SNMP is supported. When an error is detected, a TRAP is generated. Further, the LT4610 can be controlled through HTTP.
      • Preset Memory Function
        Up to 10 presets can be saved. Convenient registered presets can be recalled during operation. The
        LT 4611 can be started with the same settings every time.
      • External Memory Support
        Logo data and preset data can be written and saved from the front panel using USB memory devices.
      • Redundant Power Supply
        Two power supplies are built in to provide redundancy. When errors occur in power supply units, alarms are indicated on the LT4610 front panel. Errors can also be output as alarms using SNMP traps.
