Products & Solutions / Product Index VFS-3901H-1 HDTV Video Frame Synchronizer/Proc Amp The VFS-3901H-1 video frame synchronizer is optimally designed to handle the ingest and timing of HDTV video into a digital facility. It supports either composite black or tri-level reference inputs. A video proc amp is included to correct input levels. The VFS-3901 generates an audio video timing pulse on the NEO® midplane to permit separate audio synchronizer modules to track the video synchronizer. This combination allows both audio and video to be timed together into a digital facility. All modules in the NEO family can be controlled locally by means of an intuitive card-edge interface or remotely, using the Nucleus network control panel or CCS NAVIGATOR™.
