INTRODUCTION
Digital TV (DTV) is the umbrella term used to describe the new digital television system adopted by the FCC in December 1996; DTV is a technology, and HDTV is just one subset of the DTV.
The objective of the course is to bring the participants gracefully through all the DTV structure, features, and theory...then give them more practical information on subjects such as decoding issues, display problems, conversion, baseband data stream handling, etc. The course will also provide an in depth and structured introduction to the technology, its uses, opportunities/possibilities, and limitations. Digital TV is not simply the numerical equivalent to traditional analog television: the issues of becoming digital are covered, as well as the relevant compression technologies.

Course Objectives
- Provide background for understanding the DTV standards
- Discuss enabling technologies lying modulation techniques
- Discuss specifics of ATSC, DVB-B-C Systems
- Discuss critical design issues, technical aspects related to copy protection
- Discuss basic problems in the system integration
Who Should Attend
The course is intended for video engineers who will have to use the technology, not compression designers. The mathematics of compression techniques are discussed briefly, but the focus of the course is on providing a qualitative understanding of the processes involved rather than their detailed analysis. If you are looking for real world answers and direction toward solutions, this course is for you.
