21.1.2 Business benefits <strong>and</strong> applications<br />

As we mentioned earlier in this chapter, <strong>IP</strong>TV offerings stem from competing<br />

needs between cable <strong>and</strong> phone service providers. Of course, new <strong>IP</strong>TV<br />

technologies <strong>and</strong> applications, in turn, benefit content providers, as well as new<br />

user experience.<br />

<strong>IP</strong> services provide a number of benefits:<br />

► To the users, <strong>IP</strong>TV technology enables them to select the content they want<br />

<strong>and</strong> pick the time they want to watch. They can use the devices they want <strong>and</strong><br />

available to them. Thin clients will be embedded in various devices.<br />

► The content providers add new distribution opportunities. They can provide<br />

targeted custom TV services <strong>and</strong> commerce with the collection of usage data.<br />

► The application service providers can simplify integration of <strong>IP</strong> content <strong>and</strong><br />

services (such as <strong>IP</strong> packetized weather, games, photos, <strong>and</strong> music on TV).<br />

For example, TV can be integrated with broadb<strong>and</strong> home devices though a<br />

set-top box (STB). The <strong>IP</strong> STB is the TV’s gateway to digital music, home<br />

videos, <strong>and</strong> photos.<br />

► The network infrastructure gets filled with new traffic to increase utilization of<br />

the ever-growing fiber b<strong>and</strong>width.<br />

► The cable <strong>and</strong> phone service providers find a level play field to compete in<br />

trip-play for data, voice, <strong>and</strong> video.<br />

► Traditionally, cable <strong>and</strong> wireless offered separate (no overlap) services with<br />

different network infrastructures. As they move toward the same service<br />

space <strong>and</strong> with a common <strong>IP</strong> domain, we (the authors) predict integration <strong>and</strong><br />

mergers across cable <strong>and</strong> phone industry, as a consequence of the same<br />

triple-play ground place.<br />
