It's About Precision Time

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. Fortunately, a solution is available, in the form of IEEE 1588 Precision Time Protocol (PTP).  When used properly, this technology can synchronize device clocks to within nanoseconds across a large network with many hundreds of nodes.  When these clocks are derived from GPS (Global Positioning System) signals, PTP can provide a very accurate and stable timebase for all types of signals within modern media operations.  

In this white paper we will cover:

  • Why PTP?
  • Using the SMPTE Epoch for Synchronization
  • The Benefits of PTP
