Updating Video Playback
109
Overview
Each Firefly on your network must have a unique serial number.
This serial number will be used to identify the individual Firefly
during a multicast update to ensure that the proper media goes to
the correct player.
Within Firefly multicasting, two multicast modes are available:
Package Mode and Script Last Mode.
Package Mode:
In Package Mode, a package must be created and sent to the Firefly
system. It must contain a script (playlist .fpl / update packet .tar)
and the inclusion of videos and graphic overlays is optional. Any
videos or graphic overlays not referenced by the script will be
deleted upon arrival.
After the transfer is complete, the standard cleanup routine will
take place to reduce the amount of content on the system to
maintain a “Reserve MBs” of free space. This extra free space is
needed to ensure that the next incoming multicast transfer has
adequate space to complete. The amount of free space you will
need to maintain will need to be twice as much as your largest ever
anticipated update. See Reserves MBs: on page 111 for details.
Standard “SiteID” naming of scripts can be used with Package
Mode to remove unneeded content on the Firefly(s) if you wish to
send the same package to all Fireflys in your network.
