It's Not a Website!
iTV gives viewers an
interactive experience on their television sets. A form of iTV most
familiar to digital cable and satellite television subscribers is the IPG
(Interactive Programming Guide), an operational menu of available
programs and services that can be launched overtop of a running
broadcast TV signal. This onscreen guide allows viewers to see what
shows are available, change channels, set onscreen reminders of upcoming
shows, and even set future programs to automatically record onto a hard
drive in their digital set-top box.
iTV can also take the form
of virtual channels which, unlike traditional
"passively experienced" broadcast TV channels, deliver a dynamic
combination of discrete video, graphics and text that a viewer can
directly interact with. Virtual channels can either provide
stand-alone content, such as Video on Demand (VOD) programming
– TV
shows and movies "broadcast" specifically for the viewer who selects
them, which can be paused, rewound or fast-forwarded much like
content on a DVD. Or they can enhance an existing broadcast
channel, for example by allowing a viewer to instantly call up a table
of player stats over a game-in-progress.
The work samples
included in this section are all designed for viewing and
interaction on a television screen and not a computer monitor. To learn
