and Nearline Files
3.1 TERMINOLOGY
From IPDirector version 5.6, the following terms have been introduced:
Term Definition
Nearline Any IT storage, other than the XT[2] servers, present on
the network and where A/V material can be backed up.
These IT Storage devices are inventoried into the
IPDirector database.
Examples of nearline storage: IP drive, XFile drive, SAN,
NAS…
On-line nearline file A file is stored on the nearline storage and the physical
nearline storage (for example an XFile Disk) is still
present.
It can be a hi-res file or a lo-res file.
Off-line nearline file A file is stored on the nearline storage but the physical
nearline storage (for example an XFile Disk) is no longer
present in the housing, and is therefore off-line.
It can be a hi-res file or a lo-res file.
3.2 WHAT COMPRISES A CLIP?
Clips are logical entities that contain A/V media.
A clip element is the physical resource inside the clip: XT clip or nearline file.
Every element in a clip shares the same T/C IN, T/C OUT and metadata set.
