A new timing and reference system from Telestream aims to address synchronization challenges in hybrid SDI/IP environments. The SPG9000 offers advanced features including two independent 1G/10G IP ports for Precision Time Protocol (PTP) messaging and a dual-band multi-system Global Navigation Satellite System (GNSS) receiver.
Key Features of the SPG9000
The system can operate as a Grandmaster, Leader, or Follower in PTP network configurations. It supports dual Leader, dual Follower, and Follower + Leader setups, ensuring flexibility in diverse network architectures.
Charlie Dunn, SVP of Video Test, Synchronization, and Quality Assurance Business Units at Telestream, highlighted the importance of such features: “As video transitions from SDI to IP-based platforms, a hybrid environment that supports both technologies will be necessary for years. The SPG9000’s dual PTP pathways and GNSS reference clock sources make it well-suited for these needs.”
GNSS and Test Signal Generation
The SPG9000 integrates a dual-band, multi-system GNSS receiver that can utilize multiple satellite constellations including NAVSTAR GPS, GLONASS, Galileo, BeiDou, and QZSS. This capability allows the system to maintain accurate timing even in global markets.
In addition to its synchronization features, the SPG9000 includes a test signal generation capability that supports IP and SDI formats. Users can optionally activate this feature with a software license, which enables multiple video/audio/data generators for various resolutions and SDI rates.
Redundancy and Remote Management
The system features dual power supplies — one active and one idle backup — to enhance reliability. This design minimizes the risk of simultaneous failure, providing robust redundancy.
The SPG9000 also offers a secure web interface for remote operation and a REST-style HTTP API for easy integration into existing workflows. These features facilitate management and maintenance of the system from anywhere.
