PTP Synchronization over Wide Area Networks
For IP-based broadcast and video production applications, Precision Time Protocol (PTP) is used as the timing reference for the facility. It is typically used over dedicated local media networks using PTP-aware networking equipment (such as Boundary Clock or Transparent Clock switches), but it may be surprising to learn that PTP can also operate over general-purpose wide area networks (WANs). The Telestream SPG9000 master clock and sync generator includes several features that enable this mode of operation.
