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)
  • VITC (SMPTE12M-1/SMPTE ST309M)
  • 720p50 Hz (SMPTE296M3)
  • 1080i25 Hz (SMPTE274M6)
  • 720p59,94 Hz (SMPTE296M1)
  • 1080i29,97 Hz (SMPTE274M7)

Supported time code formats:

  • LTC - Linear Time Code (25 fps, 23,98 fps, 29,97 fps, 29,97 fps Drop Frame)
  • Digital Audio Reference Signal (DARS):
  • Resolution: 24bits
  • Base frequencies - 44,1 kHz and 48 kHz

Word Clock rates:

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.
Relative Humidity Max. 85%
Status Info St: Status of VSG181
  • In: Synchronisation status
  • LED A: Status of Black Burst output
  • LED B: Status of LTC output
WEEE Status of the Product This product is handled as a B2B category product. In order to secure a WEEE compliant waste disposal it has to be returned to the manufacturer. Any transportation expenses for returning this product (at its end of life) have to be incurred by the end user, whereas Meinberg will bear the costs for the waste disposal itself.
