Introduction To Next-Generation Multimedia - HDTV Essentials

When trying to understand modern home theater technology, the most fundamental piece of equipment to consider is the high definition display. This is usually referred to as a High Definition Television, or HDTV, even though early models were actually only high definition displays with no actual tuners. Since they're still designed around future hi-def TV technology (as are formats like HD DVD and Blu-ray), they're grouped together for purposes of this introductory guide. Projector technology is also discussed as it shares many features with HDTVs.

This guide is intended to provide a broad overview of high definition display and transmission technology and the basics of digital television broadcast and reception. Whether you're trying to make the most of your existing HDTV or educate yourself before purchasing a new unit, understanding these subjects can mean the difference between a good home theater and a great one.
