This tutorial is aimed at those of you who are moving to the interactive TV world, either from a background in PC software development, or as a manager who needs to know more about this funny DTV stuff.
This tutorial can be split into two main sections: the first section covers the basics of digital TV systems and how DTV signals are transmitted, while the second section takes a detailed look at the DSM-CC standard that is used by most digital TV systems for broadcasting data streams.
There’s a lot of technical stuff in the next few pages, but we’ll try and keep that to a minimum unless we explicitly have to. Some parts of this are more technical than others: only people who really need to know the gory details of DSM-CC should try to read past the introduction to DSM-CC, for instance.
