The Oracle Video Server System Architecture
1-4 Getting Started with Oracle Video Server Manager
Tier 1: Client
The client tier resides completely on the client machine(s) and consists of the
following components:
■
Oracle Video Server Manager: The Oracle Video Server Manager console is a
Java application that gives you point-and-click control over OVS services,
clients, and content.
■
Oracle Video Client: The Oracle Video Client software enables you to develop
interactive, video-based multimedia applications for such uses as computer-
based training, interactive kiosks, corporate repositories, and Web sites. The
Oracle Video Client software provides several tools to help you build and view
client video applications. For more information about the Oracle Video Client,
refer to the Oracle Video Client Developer’s Guide.
Tier 2: Application Server
The Application Server tier consists of the following components:
■
Oracle Video Server: The Oracle Video Server is an end-to-end software
solution for networked client-server computers which store, manage, deliver,
and display digital video on demand. The Oracle Video Server is supported on
a variety of server platforms and scales to many users.
■
Oracle Video Server Cartridges: A cartridge is a manageable object that “plugs
into” and extends the functionality of another piece of software. Cartridges use
an IDL (Interface Definition Language), a language-neutral interface, that
allows the cartridge to identify itself to other objects in a distributed system.
Any customer or vendor can write a cartridge or service that plugs into the Ora-
cle Video Server system. For example, a real-time encoding vendor might write
an encoder cartridge that integrates with the Oracle Video Server, as shown in
Figure 1–1 .
Tier 3: Data Server
The Data Server machine contains the target service(s) which the client needs to
access to get application-specific data. In the Oracle Video Server system
environment, the Server tier consists of the Oracle database (optional). A database
is a set of dictionary tables and user tables that are treated as a unit. The OVS
system can use the Oracle database to write and query database tables associated
with OVS processes, including logical content, clips, and broadcast programs.
