5.6 Content Auto Update
VideoPoster-IV can periodically poll a remote FTP server for new playlists using a given interval. This menu
allows you set up the connection to a remote FTP server that provides playlist updates.
To setup content auto update the following form fields must be filled out:

Check the Enable polling checkbox to activate polling (disabled by default)

Enter hostname or IP of the FTP server in the FTP server field

Enter the number of the FTP server’s port (usually 21) in
FTP port

Provide a valid username and password in the Username and Password fields

In Playlist dir provide the path on the remote server where the PlaylistContent directory is located.
Please do not append “PlaylistContent” to this path and make sure that the folder exists!

The Polling interval field is used to specify the interval between polls in seconds
On submit a connection check will be executed. If the browser lists the contents of the PlaylistContent directory
on the FTP server all settings are correct and polling will be enabled. For backward compatibility when the
PlaylistContent directory is missing the device will use the directory specified in
Playlist dir directly instead.
VideoPoster-IV uses the following sequence for content update:

Check the playlist.ddx file on the FTP server. If its size or last modified time has changed since the
last download, the file will be downloaded

Verify playlist file properties to make sure it can be played on the device. If it can’t, it will be discarded.

Check which media files are new or changed and thus not available locally yet

Download all new media files and store them locally. If any file is missing, the playlist will be discarded.

On success stop playback and move all downloaded files from the intermediate download directory to
the live directory.

Delete all outdated media files from the local storage and schedule new show for playback

Restart playback with the new playlist
The device is also able to just update individual files in the playlist. This is intended for situations where some
items of the playlist are provided by a third party. These items must be marked as
extern in the playlist
– please
see playlist specification documentation for details.
