Oracle Video Server (OVS)
2-6 Introducing Oracle Video Server
Whenever you create a tag file for a physical content file, the tagging utility
automatically stores this information in the database:
■
a physical content description of the tag file
■
a clip representing the entire physical content description
■
a logical content title representing the clip
If you as the administrator do not define additional logical content titles and clips
to customize the content your clients can request as in
Figure 2–1 , clients can only
request the logical content titles for individual physical content files.
Since logical content definitions are stored in a database, defining logical content
does not create new physical content files or modify existing ones.
Storage
The OVS stores physical content in the Oracle MDS (Media Data Store), a real-time
file system for storing and delivering uninterrupted video in real time. This section
describes the MDS.
The OVS optionally stores logical content in an Oracle database. For information on
how Oracle databases store data, see the Oracle Concepts manual.
Real-Time Access
The MDS can tolerate disk errors and variance in disk latency and still provide real-
time access to content. The MDS can also deliver video in real time while you are
administering the MDS.
Files
The MDS can store these types of files:
■
video files
■
audio files
■
BLOB (binary large object) files
■
tag files
