Playing back the schedule simultaneously in multiple projectors
By synchronizing the date and time of the projector with the NTP server, you can meet the playback timing of the
schedule among multiple projectors. Use this function when you set up multiple projectors of this model in the
same floor or other close location and play back the same schedule.
Please note that even when the date and time are adjusted, a time lag of maximum one second may occur in the
schedule or the starting or ending timing of playback for each content registered in the schedule. Music content
does not support simultaneous playback.
1)
Set [STANDBY MODE] to [NORMAL].
f For details on the [STANDBY MODE] setting, refer to "Setting [STANDBY MODE]" (x page 72).
2)
Set the schedule for simultaneous playback.
f "Setting schedules for simultaneous playback" (x page 182)
3)
Set the following items.
f "Duplicating schedules" (x page 182)
f "Setting synchronization for the NTP server" (x page 184)
f "Enabling [Fixed loading time]" (x page 185)
4)
Start playback of the schedule in each projector.
f "Starting playback of a schedule" (x page 166)
Note
f To synchronize with the NTP server and perform simultaneous playback, the network for the target projectors must be established. For
details on establishing the network, refer to "Network connection" (x page 101).
To connect the projectors via wireless LAN, set the [NETWORK] menu → [WIRELESS LAN] to [USER1], [USER2], or [USER3]. If
[M-DIRECT] or [S-DIRECT] is set, the projector cannot be synchronized with the NTP server.
f To connect the projectors via wireless LAN, access point is required.
f Approximately 5 minutes (up to 15 minutes depending on the condition of the NTP server) are required to complete the synchronization
with the NTP server after the power is supplied to the projector and the projector enters in the standby mode. If the schedule is played back
during this period, a time lag of more than one second may occur between the projectors in the starting or ending timing of content playback.
f To perform simultaneous playback, use the following movie file as a movie content. If you use the movie files other than the following,
simultaneous playback function may not work properly.
g Extension: mp4, Video codec: H.264/MPEG-4 AVC, Audio codec: AAC
g Extension: mpg/mpeg, Video codec: MPEG-2, Audio codec: MPEG-1/2 Audio Layer-2
f When synchronizing with the NTP server and performing simultaneous playback, the following may occur.
g If [STANDBY MODE] is set to an item other than [NORMAL], the image will disappear temporarily when synchronizing with the NTP
server once after you have turned on the power or the power has been turned on.
g Depending on the network environment such as unstable communication condition, access to the NTP server may become unavailable.
In such a case, the image may disappear temporarily when you synchronize with the server again after the synchronization was
interrupted.
Setting schedules for simultaneous playback
Set the schedule for simultaneous playback using any one of the Content Manager in multiple projectors of
this model. Refer to "Procedure for setting the schedule" (x page 159) for how to set the schedule. Based on
the schedule set in that section, the same schedule data will be duplicated in SD cards of other projectors for
simultaneous playback.
Note
f Music content does not support simultaneous playback. If you play back the schedule containing music content simultaneously in multiple
projectors, use audio output of any one of the projectors.
Duplicating schedules
To play back the same schedule simultaneously, the same schedule including contents must be registered in the
SD card inserted in each projector. There are three ways to duplicate the schedule. Use any one to duplicate the
schedule.
f "Duplicating data in SD card" (x page 183)
