Updating Video Playback

FTP Updating 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 When moving font files (.ttf) via FTP, set FTP mode to binary. on page 107.

Playlist Parsing Routine

Once the new playlist(s) has been copied to the Firefly, it is analyzed to determine which 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 FTP site. Any files that are found to exist already on the Firefly's hard drive are compared against the file by the same name on the FTP site. If the file on the FTP site is found to be identical in size, this file is not copied. If the file on the FTP site is found to be of a different size, the file is copied from the FTP site to overwrite the pre-existing file. The file size is chosen as the key in this decision as it is virtually impossible to create two MPEG files with different content that come out to be exactly the same size. This is a much more reliable indicator than creation date or other conventional means.

Once all of the required video files are copied from the FTP site, the Firefly will begin playing the new playlist or schedule.
