The MXF Book

Chapter 3: Physical and Logical Structures within an MXF File

Bruce Devlin

Overview

This chapter is organized as an alphabetical reference to the terms and concepts used within MXF. Chapter 2, a general overview of MXF, can be read from start to finish and introduces all the terms explained in this chapter. Indeed, it is assumed that the reader is familiar with those terms before diving into the detail of this chapter. Chapter 3 is intended to be read on a section-by-section basis and provides further explanation of the individual concepts. It also allows individual sections to be referenced by implementers and specification writers. If you feel this chapter is missing any detailed explanations, please contact the publisher or the author to request additions for any future revision of this book.

This chapter contains several UML diagrams. These are introduced in Chapter 2 and explained in more detail in Chapter 13, where they are used more fully to explain the MXF data model. This chapter covers the following subjects (arranged in alphabetical order):
