Disable Time Synchronization
No time information will be sent or received by this player.
Enable Time Receiver
The player will offset its time to match the beacon with the
same address and port.
Enable Time Beacon
The player will periodically multicast its system time to
the receivers.
Multicast Address
This must be a valid multicast address used to send time
information.
Multicast Port
The multicast port used to send time information.
Time Beacon Delay (s)
The time interval between sending each time information
packet. The recommended value is 10 seconds. This figure
will affect how long a receiver has to wait for an update
when first powered on.
• If a player configured as receiver, receives time
information while playing such that its offset changes,
the presentation display may be disrupted for up to four
seconds.
• To allow for any clock drift, if the time offset change is
small ( < 0.5 seconds) the player will jump to the new
time. Any video or audio may freeze momentarily if time
jumps backward. In practice, if the beacon delay is
small, any clock drift is unlikely to cause the offset to
change by more than a frame at a time. This may result
in a frame occasionally displayed for slightly more or
less time than usual.
• For large time offset changes, such as when a time
beacon starts after a receiver is already playing, the
player will stop and reschedule the appropriate
presentation at the new time. The screen will appear
black for four seconds while the media is loaded and
buffered ready to play.
