SMPTE ST2059, A versatile highly accurate synchronization technology for the All-IP Studio at work
When moving to the All-IP Studio traditional synchronisation techniques like Black-burst or Tri-Level-Sync have to be replaced by a packet based method to make best use of a single shared medium. The Precision Time Protocol (PTP) is ideally suited for that matter. With the ST2059 standard SMPTE has defined PTP profile tailored to the needs of the broadcasting industry covering a large variety of different application scenarios ranging from OB-VANs to large studios, planning, configuration, deployment, and continuous monitoring is crucial for every mission critical application. Experiences gathered from extensive measurements as well as real-world applications will be presented demonstrating the performance of PTP under varying network conditions, yet also highlighting traps and pitfalls of PTP which may affect both its availability or accuracy. Different PTP enabled network topologies will be compared. This work is a joint effort with Meinberg.
