System Update Check
After Firefly has finished its update routine it will search the
/updates directory under the home directory of the FTP site for
any valid software updates. If it finds a file in this directory with
the extension “.upd” this file will be copied to Firefly’s internal
storage and executed. A .upd file is a file designated for making a
software update to Firefly(s). For more on the behavior of each
.upd file refer to the software release notes that came with the
update file.
Firefly Storage Cleanup Routine
While you copy files to Firefly’s internal storage, Firefly compares
the total amount of space required to copy the files against the
available storage space on the Firefly. If the Firefly player
determines there is inadequate space to copy a file, it performs a
cleanup routine to make room. This cleanup routine deletes the
oldest MPEG files on the system that are not used by any incoming
playlists. The criteria used to identify the oldest videos on the
Firefly is simply the date the videos were originally transferred to
the system (regardless of the media transfer method used).
Multicast Updating
Firefly Media Player is equipped with a multicast client (optional
feature). The multicast client handles the task of receiving and
writing media files to Firefly’s internal storage.
Note that for this section of the Firefly user manual, it is assumed
that you have basic knowledge of multicasting and networking.
In addition, throughout the Multicast Updating section, there will
be various references to the term “script”. For the purpose of this
section, a script may be made up of a playlist (.fpl) file and/or an
update packet (.tar) file.
If your Firefly does not have the Multicasting feature (menu items are
“grayed out”) and you would like to purchase it, contact a Visual Circuits
representative at 1-800-250-5533.
