Synchronization Solutions for the Professional Audio/Video and Broadcasting Industry



The transition from legacy SDI systems to a virtualized, IP-based environment
The Professional Broadcasting Industry is currently evolving its studio infrastructures from traditional Video/Audio signal distribution like SDI for Video, AES for Audio and dedicated Genlock/Wordclock signals towards a full IP based production as described in the SMPTE suite of standards for Professional Media over IP Networks (SMPTE ST 2110). To support the transition from SDI to IP in the broadcast industry Meinberg joined the Alliance for IP Media Solutions (AIMS) in 2017.

PTP is the selected technology for synchronizing studio equipment over IP - A live networked infrastructure environment with COTS switch equipment and live networked video devices has already been presented to the public in experimental case studies. Today it is already agreed that IEEE 1588 (PTP) will be the basis for synchronizing all clocks in a TV or radio studio. For the Audio-over-IP world, technologies like AES67 or RAVENNA already use PTP as their choice for time synchronization already.

Meinberg plays a vital role - LANTIME IMS time servers have been designed to enable coexistence and interoperability of traditional (Black-Burst, Tri-Level Sync, AES Word-Clock) and future (IEEE-1588 PTP) synchronization methods of professional Audio/Video equipment also in hybrid environments. It provides highly accurate time and frequency, derived from GNSS satellites for legacy and IP-connected devices in parallel. The system offers redundancy, flexibility and the ability to swap cards, so that the user can have the desired configuration in one unit.

By supporting multiple input sources utilizing Meinberg's IRSA (Intelligent Reference Switching Algorithm) technology, the LANTIME time servers accept GPS, GLONASS, Galileo, BeiDou, PTP, NTP, SyncE, 1PPS, IRIG Time Code or 10MHz as possible synchronization inputs.

The modular approach of the IMS platform allows field-replacement and hot-swap capabilities for IO modules and power supplies. This concept ensures future-proofness and expandibility by allowing to add or replace modules when new technologies or interfaces are required and makes this product one of the most scalable and flexible synchronization solutions on the market.
