Aligning to the SMPTE Epoch for Synchronization
With the transition to IP networks for all aspects of the signal processing path, accurate timing becomes more difficult, due to the fundamentally asynchronous, non-deterministic nature of packet-based networks. With Ethernet networks, which are inherently bi-directional, it is possible to distribute a common time signal using IEEE 1588 Precision Time Protocol (PTP) to every device without a separate overlay sync network. Each device can then accurately synchronize its internal clock to a single master clock which can then be used to accurately achieve media signal synchronization by means of the SMPTE Epoch.
Artel Takes a Closer Look at PTP in New White Paper
Artel Releases New Precision Timing Protocol White Paper. ‘Time Travels – A Closer Look at PTP’ examines the key elements and considerations of PTP deployments including PTP synchronization, master clock selection, transparent and boundary clock functions, PTP domain and profile configuration, and other network considerations.
