What is the Oracle Video Server?
The Oracle Video Server (OVS) system is a unique implementation of video server
technology for networked computers which store, manage, deliver, and display
digital multimedia data (real-time, full-screen video and high-fidelity audio) on
demand. OVS is supported on a variety of server platforms and can scale to serve
many thousand concurrent users.
This section is not intended to present a detailed explanation of the OVS
functionality, it provides a basic understanding of how the pieces of this system fit
together and relate to one another.
OVS within the Network Computing Architecture (NCA)
The OVS system is fully compliant with Oracle’s Network Computing Architecture
(NCA). NCA affords multiple computing advantages, including a “thin-client”
architecture that requires minimal data storage space on the client machine.
Similarly, the Network Computer (NC) client presents high levels of security and
error recovery; users need only use any NC client machine to log onto the NC
server. They can then restore access to any applications and data that may have
been lost because of power outage, flood, or any other damage to the client
machine.
Because of its thin-client nature, an NC client machine is also very affordable to
purchase, deploy, and maintain.
Figure 1–2 shows OVS in the NC environment, a scalable, object-oriented
architecture, which consists of three tiers and three layers.
