Profile XP Media Platform system overview
The Profile XP Media Platform system is an extension to a standard PCI bus-based
Windows NT computer. This standard is enhanced to add functionality and performance
necessary to deliver an industrial grade, broadcast-quality disk-based video server. This
section discusses the major architectural blocks, what they do, and how they
interconnect.

The Profile XP Media Platform has three subsystems: Application Subsystem, Real
Time Subsystem, and Storage Subsystem.
Application Subsystem
The Application Subsystem is a Windows NT computer subsystem. The Application
Subsystem provides a platform for running Windows based applications for configuring
and controlling the Real Time Subsystem both locally and remotely.
Real Time Subsystem
The Real Time Subsystem contains a real time processor and peripheral devices and runs
the VXWorks operating system.The Real Time Subsystem manages all the hardware
involved in controlling the flow of video, audio, timecode in and out of the system. This
includes video I/O boards, audio I/O boards, video compression boards, and networking
and storage. The Real Time Subsystem is controlled by applications running on the
Applications Subsystem using Inter-Processor Messaging channels (IPM). It is
responsible for the execution of events on the play timeline.
