7 System Software Update Process
If a CD/DVD disc fails to qualify as a media update or a Drop & Go
update, the Mantis determines if it is a system software update. To
qualify as a system software update, the disc must contain a file
with the extension “.upd”. If such a file is found, Mantis processes
the software update, ejects the disc, and then waits 60 seconds
before implementing the update and restarting.
If no valid (.upd) file is found, Mantis takes no further action.
Content Log
Once every 24-hours, the media player creates a content log that
lists all of the content files stored on the player. This log is an
ASCII delimited file that provides the media name (filename), file
size in bytes, and mtime (file creation time).
mtime is , the file creation time, or modified time in a Linux format.
During the storage cleanup routine, the Mantis uses the file
modification time to determine which files should be removed to
open up free space for new content.
Figure 46. Content Log File
The Content Log is one of the files downloaded from the Mantis
when uploading log files.
