SCOPE
Video on demand has evolved as a major implementation problem for
network integrators. Clients want the ability to retrieve and view stored video
files asynchronously at near broadcast quality, on a local host. Some problems
integrators face to achieve this goal include: video content preparation, server
storage, network throughput, latency, client interfaces, quality of service, and
cost. This paper addresses the design considerations for a private video on
demand implementation.
INTRODUCTION
The Initiative for Worldwide Multimedia Teleconferencing and Video Server
Standards
The market for multipoint multimedia teleconferencing and video server equipment
is poised for explosive growth. The technology for this necessary and much-
anticipated business tool has been in development for years. By the turn of the
century, teleconferences that include any combination of video, audio, data, and
graphics will be standard business practice.
Compliance with teleconferencing standards will create compatible solutions from
competing manufacturers, feeding the market with a variety of products that work
together as smoothly as standard telephone products do today. Specifically, with
the adoption of International Telecommunications Union (ITU) recommendations
T.120, H.320 and H261, multimedia teleconferencing equipment manufacturers,
developers, and service providers will have a basic established connectivity
protocol upon which they can build products, applications, and services that
will change the face of business communications.
New Business Imperatives
Voice on Demand systems are starting to be required by commercial, industrial,
governmental and military associations to retrieve past information in order to
prepare and anticipate future events. This preparation and anticipation can be
crucial to the survival of these industries because of the key roll of the
individuals or groups being monitored. It is this monitoring and collection of
data that allows these organizations to make informed decisions and to take the
appropriate action to current events.
Multipoint multimedia teleconferencing and video servers offer the required
