Appendix
B
Theory of operation
This appendix is a high-level overview of the Profile XP media platform that provides
a basic understanding of system operation to support module-level servicing.
Architecture overview
The Profile XP architecture is an extension to a standard PCI bus-based computer that
uses the Window NT operating system. This standard computer base is enhanced to
deliver an industrial strength, broadcast quality, disk based video server. This section
describes the major architectural blocks, what they do, and how they interconnect.
The Profile XP system can be viewed as three main components or subsystems: the
application subsystem, the real time subsystem, and the media storage subsystem,
along with the platform resources required for operation. The real time subsystem, the
application subsystem, and the platform resources are contained within the Profile XP
media platform. The media storage subsystem consists of one or more separate RAID
chassis.
The block diagrams that follow show the subsystems of the standard definition and
high definition Profile XP media platforms.
