14.1 Assets
Asset info is created in TX/MAM, or imported. Asset info is stored in the TX/MAM database.
Asset files (Essences) are ingested and stored on the Storage server.
Files and Assets are linked based on the Asset’s External reference, as shown below:
Example Asset
Original Filename External reference AssetID Filename in TX/MAM
abc123.mpg abc123 153 a0000153.avf
Media files are renamed to a0000. (7 digits) during ingest.
The file extension for clip files is renamed to .avf.
Example: a0000153.avf
When a schedule is imported and Assets in the schedule do not yet exist, empty Assets are created.
When a Playlist is activated, the playout_distri process will check if Asset files are still in cache on the
playout node. If not, files are fetched from the Storage-server and transferred to the playout directories
on the K2 Edge.
14.1.1 Creating Assets via TX/MAM
1) Assets (Asset info) are created in TX/MAM. Until a file has been ingested, these Assets are
called empty Assets.
