How Is Digital Video Used?
Concepts 1-9
■
audio and video are not synchronized
■
the screen is blank for short instances of time
The Oracle Video Server system anticipates these challenges and provides effective
high-level tools to address them. For example, OVS uses several means of ensuring
that your digital video delivery is reliable and won’t be interrupted in the event of
a failed disk or a bad video stripe. In addition to
RAID (Redundant Arrays of
Inexpensive Disks) Protection , OVS offers the ability to create Spare Disks
(physical storage space into which you can temporarily transfer content in the
event of a disk failure) and use hot-swapping (a technique to transfer digital-video
data to a spare disk without bringing down the video server system or losing video
service).
How Is Digital Video Used?
You can use Oracle Video Server to incorporate digital video into a variety of
applications, such as interactive training-on-demand, product announcements,
CEO messages, point-of-sale kiosks, web sites, corporate repositories, pay-per-view
television and multimedia catalogs. These multimedia applications can provide
your company with competitive advantages which dramatically improve
productivity while reducing costs.
This section describes some of the interesting ways in which you can use OVS.
Clips and Logical Content
When commercial video subscribers request a “feature” video, the video they
actually see will probably also contain advertisements for available products and
services. There may also be previews of other movies, concerts, and events soon to
be available on digital video.
Each of these short segments is known as a clip. The OVS enables system
administrators to assemble these clips as they see fit, then label the assembled clips
and videos with a single title, to make retrieval and delivery easier. Because these
clips do not actually need to physically be assembled into a single file, but are
accessed from their physical locations by OVS’s internal logic, they are referred to
collectively as
Logical Content . Much as beads can be strung together in many
different combinations to create a single unified piece of jewelry, logical content
clips are “strung together” to create a single logical content title, or a single unified
stream of digital video.
