What Are the Challenges of Digital Video?

Customizing the Video Client

The Oracle Video Client can do more than simply request and display digital video.
Its true power lies in its ability to act as a platform that enables you to develop
completely customized video applications for use in computer-based training,
information kiosks, Web sites, and corporate information repositories.
The OVC software comprises a variety of components, each extensible and
customizable, including:
Developers can then deploy the base video client on various machines, using these

Such latencies are extremely noticeable in time-dependent applications such as
video, and show up in the form of glitches such as:

Java native classes and a Java player applet, to afford complete consistency and
portability across a variety of operating platforms, such as Microsoft Windows
and various "flavors" of the UNIX operating system. Use of a Java-based video
client also eliminates the need for an installed HTML browser on the target
platform. Additionally, a Java-based client implementation enables smooth
integration and use on Java-based devices such as NCs and set-top boxes.
Web Plug-in, for use under a browser in HTML pages.
ActiveX control, to integrate the video client into applications designed to
operate in the Microsoft Windows 95 or Windows NT operating systems.
retrieve large encoded content files from storage,
stream these files at high delivery rates across a network that may be
unreliable, and then
reassemble, decode and display the streamed content on a client device.
misaligned or non-corresponding parts of the video screen
some (or all) parts of the screen stop moving
