Updating Routine Order

The Firefly system will look for an update file following a specific
order. It will proceed sequentially through this order until it finds a
matching file and will then proceed to the Playlist Parsing Routine
(see below).
1. siteid.tar
2. firefly.tar
3. siteid.fpl
4. firefly.fpl
5. siteid.fsc
6. firefly.fsc
7. *.tar
8. *.fpl
This logic is intended to allow users to create a single CD or DVD
that will work on several Firefly's. All of the media required for all
of the Firefly's can be placed on this CD/DVD along with separate
update packets targeted for each Firefly (using the site ID as the
target mechanism). A generic firefly.fpl playlist or firefly.fsc
schedule can also be included to cover any of the Firefly's that do
not require unique content.
Playlist Parsing Routine
Once the new playlist(s) has been copied to the Firefly, it is
analyzed to determine what MPEG video files are required to play
it. Firefly then checks its own storage to determine if any of these
videos are already present. Any files that are not present are copied
from the CD or DVD. Any files that are found to exist already on
the Firefly are compared against the file by the same name on the
CD or DVD. If the file on the CD/DVD is found to be identical in
size, this file is not copied. If the file on the CD/DVD is found to
be of a different size, the file is copied from the CD/DVD to
206
