SDI/AES Synchronizer Processor DESCRIPTION The AVS-3901-B,C is a single module for high quality audio and video synchronization which synchronizes AES audio signals with an associated video signal. A DARS and genlock reference inputs provide for AES-11 compliance. AES input and output ports provide full bandwidth 16 / 20 / 24-bit capability, as well as compressed (Diamond, DOLBY-E) pass-through capability. One SDI input with two outputs are provided. This module, as is the case with all modules in the NEO family, can be controlled locally via a front-edge display or by remote communications allowing for remote control, monitoring and diagnostics using hardware control panels and/or a GUI. This module can be used in combination with other NEO modules to provide added video and audio capabilities such as audio tracking delay and hot-switching.
AVS-3901 FEATURES SDI video input with two processed video outputs Two AES streams (unbalanced or balanced) input and output Unbalanced DARS input (balanced input available on -B option) Genlock reference input with loop through Internal audio processing amplifier Selectable 16 / 20 / 24 bit audio processing Audio re-sampling for 32-108kHz AES outputs, with bypass for data over AES operation Diamond or Dolby-E) C, U & V bittransparency Command Control System (CCS) Enabled DejaView intelligent settings recovery system FS Function Vertical Phase Horizontal Phase Frame Sync Mode Video OP Mode Freeze Type Force Freeze Video IO Delay FB Video Frozen Fade Rate Track Video

Controls the insertion of FS circuit in signal processing path. Adjusts the vertical timing. Adjust the horizontal timing. Selects the operational mode for the Frame Synchronizer. Selects the output video mode when the input video is disrupted. Selects a type of video freeze. Forces the output video to freeze. Returns the input to output delay within the Frame FIFO memory. Returns the output video frozen status. Controls the rate of fading when channels are swapped or muted. Tracks automatically the delay introduced by the video frame synchronizer. Selects the output audio mode when the input video is disrupted. Bypasses the Audio Synchronize function. Allows passing of signals to downstream card for concatenated function. Delay adjustment for DARS Input signal. Returns the presence of input DARS signal. Returns the locking status of DARS Input with respect to external reference video signal. Sets the Genlock Standard (NTSC PAL_B PAL_M or AUTO) Returns the detected external reference signal standard. Returns the presence of the video signal from the external reference source. Returns the locked status of the external reference signal. Returns the presence of the Burst signal from the external reference source. Returns the detected SC/H relationship from the external reference source. Selects the reference source for the on-board Genlock circuitry. Reports the software version. Recalls the factory setting.
