Abstract

High definition television is an emerging technology1-9. Its presence marks a major change in the way the medium of television will be presented in the near future. A possible indicator of HDTV’s impending success in the marketplace would be the emergence of DVD (digital versatile disk) as the fastest growing new video medium to date. DVD movies are designed to use both NTSC television capabilities as well as the new standards for television and digital display. The next step in this process is the conversion of broadcast television to this new and vastly different technology. This change is now taking place. Many television stations are broadcasting at least a portion of their programming, simultaneously, in HDTV and the older NTSC format. The coming changes will create a large demand for technicians trained in the medium of HDTV.

I. Introduction

The purpose of this research was to develop a technology course for 2nd year EET students that will introduce them to HDTV and allow for reasonable success in seeking and obtaining a career in industry maintaining HDTV transmission and reception systems.

Knowledge required will range from a modest background in digital representation of analog signals to an extensive understanding of practical diagnosis and maintenance of signal transmission and reception equipment. Topics that need to be covered will include: analog to digital signal conversion, audio and video compression, digital compressed signal decoding, a comparison to current NTSC TV technology and standards, industry standards and definitions and their development pertaining to HDTV, a brief overview of similarities and differences in worldwide implementation of the technology, hardware diagnosis and repair, transmission system design and implementation. Most mathematical and basic principles background will be covered in the regular EET course work. The major obstacle to this planned course will be the introduction of transmission of digital signals.

The recent development of an HDTV transmission standard that is being accepted by industry is
