Media Architectures fit for the IT data center
Contributed by Dr. Richard Cartwright, Principal Software Architect, Quantel Ltd.
SYNOPSIS: One of the challenges facing the professional media industry is that we increasingly find that the technologies in our plants are IT-centric, and that the designs and concepts we use to build facilities are coming from the IT world. It is incumbent on us as an industry to be able to operate comfortably both in the traditional media technology space and in the IT technology space. To that end, the JT-NM system view provides a bridge between these worlds in the important areas of technologies, virtualization and service replication and modeling. Each of these will be discussed (and build on each other), in turn.

The Minimalist Reference Architecture
Contributed by Charles Meyer, Chief Technology Officer, Production, Grass Valley, A Belden Brand
SYNOPSIS: There is no one answer for how to monetize content. But the tools needed to create, produce, transport, and distribute audio and video are finite and, in fact, not really that great in number. How media is processed can be very unique. This is the artistic, or creative factor that differentiates between media types, styles and content. And the elements that guide how media is consumed are based on human factors and time. It seems very logical to conclude that a viable Reference Architecture can be developed which enables media manufacturers to provide interoperability for their customers. It is indeed amazing to consider how such a simple set of principles leads to the enormous diversity of media offered to today’s consumer.

Modeling with the Unified Modeling Language (UML) – A Tutorial
Contributed by Dr. Richard Cartwright, Principal Software Architect, Quantel Ltd.
SYNOPSIS: By modeling the elements of human experience that are monetized by content businesses, and by doing so using a common language that is understood widely in the IT industry, a new breed of interoperable networked-media systems can be designed and built. The result of this modeling exercise will be a concise, reusable architectural framework that is captured both as: a few pages of paper; a computer-based model that can automatically be transformed into skeleton code. The value of models is as much about providing a common language with which to explain what is being modeled in an IT context, facilitating easier dialogue between the worlds of IT and media professionals, as it is about a JT-NM user-story-derived Reference Architecture models.
