How Is Digital Video Used?
1-10 Introducing Oracle Video Server
This concept is also the way you construct a playlist on your home CD player. For
example, if you have three CDs loaded into your player, you may find that you like
the first four tracks of the first disc (but not the fifth track), all of the tracks on the
second disc, and only the eighth track of the third disc. You can program your
player to play only these tracks, in any sequence you choose, and give this
assemblage a single name to be stored in the player’s memory for easy retrieval.
Logical content within digital video files works in nearly the same way, except that
a database is required to track all of the many possible combinations of video clips.
Figure 1–3 shows one possible way in which logical content might be used to
assemble a children’s cartoon show; the basic process will work the same way
when any video subscriber chooses a video using logical content capabilities.

You can also write OVS applications that define logical content titles dynamically.
These applications can customize logical content based on users’ interests and
viewing history. For example, the application could program the advertisements
that show during a movie based on the interests of the viewers.
