ABSTRACT
The purpose of this introductory chapter is to acquaint the reader with the technology the book will focus on, beginning with a definition of the technology. Once that is accomplished, we will compare that definition to other television delivery methods, including standard over-the-air, digital satellite, and cable television. Using the preceding information as a base, we will conclude this chapter by examining the existing and potential utilization of IPTV. This information will enable us to obtain an appreciation for how IPTV can be used as well as allow us to note the advantages and disadvantages associated with its use. In concluding this chapter we will examine the potential impact of IPTV. Because IPTV represents a series of technologies, we will primarily focus on the delivery of television shows, movies, and similar content via private IP-based networks. However, prior to doing so, we will examine the network elements common to different types of IPTV services to obtain an appreciation for the general manner by which video content can be delivered to consumers over both public and private IP-based networks. So, let’s grab a soda and perhaps a few munchies and begin our exploration of IPTV.
