cation industry is somewhere in the middle of that adoption continuum. It is a market that is becoming less constrained by technology than by human habits. The stigma of videoconferencing is that next year has always been the year it was going to take off. However, with the proliferation of broadband Internet, and now broadband wireless Internet to phones (if one can still call them that), the future of video communication is finally clear. We dedicate the remainder of this book to fostering in the reader an understanding of video communication applications, the technologies upon which they depend, and the key decision points one must consider when making a product or service selection. Once mastered, we believe, more than ever, that most readers will extol the benefits of video communication, and will want to gain first-hand experience. It is our hope that they will make video communication a habit. An Introduction to Video Communications CHAPTER 1 REFERENCES "How is IP Impacting the Current Videoconferencing Market?"
