Scenario 3: Internet Environment

In the Internet environment, the process of delivering digital video is much the
same as in the broadband environment (for details, see
Environment
No "membership subscription" is required to the corporate network. The client
device is a computer which is also used for other purposes, rather than a set-
top box. The delivery network is also not solely dedicated to video.
The client application used for video display might be deployed as part of
another application such as an e-mail or groupware package. For example, you
might choose to deploy a video client as an ActiveX component in a Windows-
based application you are developing, to provide "one-on-one" video training
to the application's new users. Or, you might use the Web plug-in client to
enable viewers to browse corporate intranet pages and view the videos those
pages reference.
Depending on the bandwidth available, video may be shown full-screen or in a
window on the PC, and at various frame rates.
Logical content is available (assuming a database is used to store such
content), and the nature of it is tailored to corporate needs. For example, a
digital video introducing a new product might begin with a clip of the
company CEO giving a short speech. For a description of the capabilities of
logical content, see Clips and Logical Content
on page 1–16), except that:
The network communication layer, rather than consisting of a dedicated high-
speed broadband network, will instead consist of PSTN (Public Switched
Telephone Network) over the publicly accessible Internet, or another protocol if
the Internet is accessed from within a corporate-specific intranet. Over the
Internet, this layer uses such communication protocols as TCP (Transmission
Control Protocol) or UDP (User Datagram Protocol).
The client device is a PC, NC, or set-top box running an HTML browser or
applications written in the Java programming language.
The client application used for video display might be deployed as a plug-in
(an extension) on the associated HTML (Hypertext Markup Language, the
basic language of Internet pages) page, or as a Java application or applet.
Video is generally viewed in a small window with quality reflecting the
bandwidth of the connection.
