  • A DVD Primer
    March 2004 A DVD Primer From DV to DVD: Enriching the experience of high-quality video from the Adobe Digital Video Group A DVD Primer: INTRODUCTION INTRODUCTION From Stone Age to Bronze Age to Industrial Age to Information Age, humans have found new ways to communicate and to tell stories that educate, inform, and entertain. Audiences have evolved from polite passivity, glad to receive whatever reports, hearsay, or diversion might be found locally; through the wonder of entertainment and news choices brought to them by national and international media net- works; to an explosion of possibilities that are available on demand via cable, satellite, and the Internet. With digital technology transforming the ways in which we access and utilize information, we have wit- nessed the dawn of the Interactive Age. We have become a society enraptured with decision-making on every level—empowered to choose exactly what to read, listen to, and view; when, where, and how. So it comes as no surprise that by 2000, within just three years of its introduction in September 1997, DVD had become the most successful consumer electronics entertainment product ever. Facilitating interactivity unfulfi lled by VHS, at a more affordable cost than laser disc, DVD has outpaced the con- sumer adoption rate of any other product in history. Analysts predict that the total market for all types of DVD systems (players, recorders, set-tops, PCs, etc.) will be over 400 million units by 2006. While DVD players have rapidly become de rigueur in home entertainment systems, and DVD drives are continuing to replace CD drives in personal and laptop computers, there have also been some other developments that have been changing the way we experience and use video: • With the availability of the DV format and affordability of DV camcorders, more and more people are producing their own videos—for work and for their own entertainment.
