1) When a Playlist is activated, playout_distri will check if files are still in cache on the playout
node. If not, playout_distri retrieves transfer metadata from the TX/MAM database (via
dataserver). Transfer metadata specifies where Assets are stored.
2) Based on the transfer metadata, playout_distri will fetch files from the Storage-server and
transfer files using FTP to the playout directories on the playout nodes. Channel Packs are
transferred from the TX/MAM database or from Storage, depending on where they have been
stored with Channel Composer.
3) The sequencer interprets the active Playlist and sends commands to nexos, the K2 Edge
render engine [see the next diagram].
4) Nexos renders the commands and files.
