You cannot use BrightWall video creation methods if you are using the Standalone publishing method, because you must be connected to a network (additional configuration is required after publishing the presentation). |
Video Walls using XC5 Players
...
Playback must be started simultaneously on all players.
You must periodically re-synchronize to correct for sync drift over time.
You must also attempt to synchronize output signal generation timing (known as "genlock" or "v-sync" synchronization).
Downstream processing on players can result in out-of-sync playback, even if players are on the same frame, corrected for drift, and have the same redraw timing:
Display smoothing or scaling can result in a frame or redraw delay. To fix this, disable display processing if possible. Otherwise, ensure that all displays are set and connected identically.
Different display sets may have different timing if unlinked parallel processors are used for wall or tile processing.
Snapshot Lag
When taking a snapshot of an XC5 player, snapshots are captured one at a time from screen 1 to 4. This results in a frame offset of three to four frames between screen 1 and screen 4 since the offset increases by one frame of video between each screen.
