Grass valley 8981FS DATASHEET

44 8981FS SDI Frame Synchronizer/Delay

Key Features

•10-bit signal processing assures broadcast quality

•Proc. amp controls

•Various freeze options for production applications

•Audio delay signal to drive audio delay cards

•Functions as frame synchronizer or fixed delay

•Up to a full frame of delay

•Cleanly handles input signal hot switches

•Passes all horizontal ancillary data (AES)

•Passes or blanks vertical interval data user adjustable

•EHD detection and insertion

•Complete remote control with GPI or Ethernet interface

The 8981FS offers unparalleled functionality. It combines the best features of a frame synchronizer, frame delay, and digital processing amplifier in one module. The 8981FS is designed to handle various environments and applications including

asynchronous input video signal timing, manual color correction, and production freeze frame applications. It operates as a companion to

the popular 8916 AES autotracking delay DA, and 8920ADT or 8921ADT for audio synchronization applications. Several control modes are also offered, including local board controls, GPI for freeze control, and Ethernet

control over a LAN/WAN using a variety of user friendly interfaces.
