Easy Time Synchronization Evaluation Over Broadcast Networks

November 14, 2019

With the start of 4K/8K TV programming, broadcast networks have also entered the era of large-capacity communications and are transitioning from SDI interfaces to IP networks to facilitate huge data traffic. IP networks have various benefits, such as long-distance transmissions, reduction of cablings, and use of lower cost network switches. However, there is an issue they doesn't support strict time synchronization among network equipment in general. There must be no dropped programming or lost synchronization, such as when switching between cameras and relays at different remote broadcast locations A and B. IP networks achieve this time synchronization using the Precision Time Protocol (PTP).
