Network Time Sources for the SV-4K Media Players
The SV-4K supports two different network time sources under the global SV-4K
settings:
l
Network Time Protocol (NTP)—This is the default.
l
Precision Time Protocol (PTP)—Required for video wall synchronization feature
and for DMP-to-DMP synchronization.
NTP and PTP settings are provisioned globally for all SV-4K media players.The Cisco
StadiumVision Director server is provisioned as the default NTP source for both the
Cisco DMP 4310G and SV-4K media players.
NOTE:
When PTP is configured, only the SV-4K PTP master
derives its clock using NTP.
For the most accurate synchronization for video playback across SV-4K devices, the
time on the target SV-4K players must be almost the same. NTP does not provide this
level of time synchronicity and accuracy, so PTP is also required.
