Profile XP system overview
The Profile XP Media Platform system is an extension to a standard PCI bus based
Windows NT Computer. This standard computer base is enhanced to add
functionality and performance necessary to deliver an industrial grade, broadcast
quality, disk-based media platform. This section discusses the major architectural
blocks, what they do, and how they interconnect. A more detailed overview of the
system is available in Appendix B, Theory of operation.
The Profile XP Media Platform consists of two major subsystems, the Application
Subsystem and the Real Time Subsystem, and the platform resources needed for them
to function. These are shown in the darker tinted area of the high-level block diagram.
A third major subsystem, the Media Storage Subsystem, is external to the media
platform.

Platform resources
The platform resources provide the infrastructure necessary to operate, interconnect,
and integrate all the components of the Application and Real Time Subsystems. The
platform resources include the multi-slot PCI bus, the video & audio crosspoint fabric,
the power supply, and system cooling.
Applications subsystem
The Applications Subsystem is a Windows NT computer subsystem in a standard
NLX single board computer form factor. The Applications Subsystem provides a
platform for running Windows based applications that configure and control the Real
Time Subsystem both locally and remotely.
