IMS-VSG
SKU: IMS-VSG
Audio/Video-Sync Generator
The IMS-VSG181 is used as a video signal reference for studio equipment and provides the generated signals at four BNC outputs. These are Bi-Level Sync (Black Burst) / Tri-Level-Sync, Longitudinal Time and Control Code (LTC), Digital Audio Out (DARS), and Word Clock.
Key Features
Four BNC outputs with configurable video and audio signals:
- Out 1: Black Burst (PAL, NTSC with VITC support), tri-level sync
- Out 2: LTC 25 fps, 23,98 fps, 29,97 fps, 29,97 fps Drop Frame
- Out 3: DARS (Digital Audio Reference System)
- Out 4: Word Clock
- Four LEDs: Signal status of module and outputs
Supported video formats:
- PAL (SMPTE259M/ITU-R BT.470-6)
- NTSC (SMPTE170M/ITU-R BT.470-7)

| Further Information | Functionality
The VSG181 is Synchronised by an external 10 MHz signal, 1PPS and a time telegram, which provides the connected reference receiver. These signals significantly determine the accuracy of the output signals. The generated video signals, in different formats, have a phase reference to the 1PPS. In order to be able to provide high-precision output signals during the switchover of the RSC (IMS systems with redundant receivers), the VSG181 has its own oscillator. |
