12.6.27 VSG - Video Sync Generator
The VSG is a video signal reference for Studio Equipment with four BNC female output connectors. The Module
generates 1x bi-level sync (Black Burst), 1x Tri-Level Sync, 1 x video sync signals (H-Sync, V-Sync or LTC)
and 1 x digital video output (DARS). The LANTIME Web Interface can be used for output signal configuration
and to query the state of the VSG.
Functionality
The board is synchronized by an external 10 MHz signal. It generates configurable video signals in different
formats. The generated signals have a phase reference to 1PPS.
Generated Signals:
SMPTE standards:
PAL Blackburst with VITC Support
NTSC Blackburst
Tri Level Sync:
