Why Digital Video?

2 Oracle Video Server Quick Start

Why Digital Video?

Communicating by video is commonplace today. Uses include product promotions,

employee training, customer education, surveillance, and record keeping.

However, in today’s corporate climate, where people expect immediate availability

of information, traditional methods of video storage and distribution are rapidly

becoming too restrictive.

Analog video, which is stored on individual tape cassettes, has several inherent

disadvantages:

■

Image quality degrades from repeated use or aging.

■

Videos can be checked out or lost from the video library.

■

Multiple copies of videos must be stored to satisfy demand.

■

Users must have access to a VCR to watch the videos.

Digital video, on the other hand, is stored on and played from a computer and is

not susceptible to these physical limitations. In addition, digital video provides

other advantages:

■

Videos can be immediately available to users via a local area network (LAN) or

corporate Web site.

■

Videos can be quickly distributed over a wide area network (WAN).

■

Any video can be viewed concurrently by many people in any variety of

locations with guaranteed availability.

■

Video applications can be interactive.

You can use Oracle Video Server (OVS) to incorporate digital video into a variety of

applications, such as interactive training-on-demand, product announcements,

corporate messages, point-of-sale kiosks, Web sites, corporate repositories, and

multimedia catalogs. These multimedia applications can provide your company

with competitive advantages which dramatically improve productivity while

reducing costs.
