IMS-VSI: Studio Synchronization Input Card
Key Features
- Accepts black & burst (bi-level sync) signals with support for PAL and NTSC
- Comprehensive VITC support, both for standard SMPTE 12M and for SMPTE ST309/MJD and ITU-R.BR.1353 variants
- Black & burst is accepted without VITC for generating a reliable, accurate frequency signal (prescaler mode), or with VITC for full time-of-day, frequency, and phase support
- SMPTE 12M Linear Time Code (LTC) 25 fps input support
- Word clock input with support for any frequency from 1 kHz to 10 MHz
- Dedicated pulse-per-second (PPS) input for connection of an external phase reference.
Product Description
The IMS-VSI module operates as a multi-reference input card, with signal inputs for black & burst (bi-level sync, with both PAL & NTSC support), linear time code (LTC), and word clock signals. A pulse-per-second input is also provided for phase synchronization, to supplement those input signals which cannot be used as a phase reference (such as a word clock). These signals can be used to create a time reference for an IP network, for example as a bridge between the analog & SDI world and a PTP timing network. It provides studios with an alternative method of reference signal synchronization if GNSS synchronization is not feasible but an alternative reference signal that provides the requisite stability & accuracy is available, and allows analog & SDI-based equipment to be synchronized with modern IP-based equipment using PTP timing.
Black & burst signals both with and without VITC (Vertical Integrated TimeCode) are supported; a black & burst signal with integrated VITC is suitable for providing a time of day, frequency, and phase reference for your IMS LANTIME system. Even a black & burst signal without VITC or a word clock signal can be used as a frequency reference, which when combined with a phase reference such as a PPS signal can be used for genlock and sample clocks.
Should you wish to integrate analog & SDI-based equipment into your modern IP-based production network and have the ability to install a GNSS antenna, Meinberg also provides studio signal output modules in the form of the IMS-VSG cards, which generate black & burst, tri-level sync, DARS, LTC, and word clock signals based on an upstream reference.
