Excuse me, what precise time is It?
Oliver Ettlin
39th Chaos Communication Congress (39C3): Power Cycles · Day 1 · Saal Ground
Oliver Ettlin's talk, "Excuse me, what precise time is It?", delves into the critical role of **Precision Time Protocol (PTP)** in achieving highly accurate time synchronization across network infrastructures. Primarily drawing from his extensive background in the professional audio and video (AV) broadcast and event technology industries, Ettlin illuminates how PTP addresses the inherent asynchronous nature of IP networks to deliver the ultra-low, predictable, and controlled latency required for synchronous media transport. The presentation goes beyond theoretical concepts, offering live demonstrations that highlight the practical challenges and solutions encountered when deploying PTP in real-world scenarios.
