2What is Interactive Television?
- Interactive television describes any number of
efforts to allow viewers to interact with
television content as they view. It is sometime
called interactive TV, iTV, idTV or ITV - Examples
- electronic program guides (EPGs)
- interactive advertisements
- mass customization of content
- video on demand (VOD)
- games, interactive game shows
- interactive drama, news, maps and weather
reports, - sports, trading, gambling, and auctions.
3Types of TV interactivity
- Interactivity with a TV set
- Interactivity with TV program content
- Interactivity with TV-related content
4Interactivity with a TV set
- It does not change any content or its inherent
linearity, only how we control the viewing of
that content. - Functions like a VCR, can pause, fast forward,
rewind, records as you go, program to record
future shows, etc. - Think TiVo, video-on-demand, and DVRs
- Simplest type of iTV. Already successful but
still has room for more growth.
5Apple announces new iTV
- A novel-sized device that allows users to
wirelessly stream iTunes video to their TV - The videos will be near-DVD quality
- Will be a direct competitor to Cable OnDemand
services and DVD rentals

6Interactivity with TV program content
- The idea is that the program itself can change
based on viewer input. - Simple Forms
- Directly incorporate virtual audience response
back into the show - Polls
- Questions
- Comments
- Already popular in many applications
- Advanced forms
- Include dramas where viewers can choose plot
details and endings - Demand is unknown, could have applications in the
future
7Interactivity with TV related content
Coactivity
- Coactive TV refers to the multitasking use of
both television and other interactive media - Web sites and mobile phone services already
coordinate with TV programs - Examples
- Get more info about what is on the TV sports,
movies, news, etc. - Get more info about advertisements, with the
ability to purchase what is advertised - a
coactive form of e-commerce (see example below)

ordering page
8TV-commerce pizza-ordering example
- The uniform HTML order forms could be transmitted
via data broadcasting, while the submission of
the order could be performed via an IP-based
return channel. - Enables transmission of the order form
unconditionally and simultaneously to all
receivers. Not likely that viewers will submit
orders simultaneously or that their orders will
be routed to the same physical local server for
processing. - When a viewer requests to order pizza, the order
form is rendered. Upon confirmation of the order,
the contents of the form is submitted over the IP
channel.

the advertiser, broadcaster, ISP, and receiver.
9Interactivity with TV related content
Coactivity
- Promises to become more general, flexible, and
ubiquitous - Based on open Web servers that dont need to be
tied to any program, network, or programmer - Can work across programs and channels, with
recorded, time-shifted programs, and across
device types. - Fundamentally, its about how human attention
moves among media content items, using available
devices and platforms
10Physical Types of User Interactions
- Two-screen iTV
- Single-screen iTV
- Internet TV (Broadband TV)
11Two-Screen iTV
- iTV is described as lean back interaction,
since users are typically relaxing on a couch
with a remote control - lean forward interaction is typically a
personal computer-oriented experience with a
keyboard, mouse, and monitor. - Two-screen" Interactive TV, involves both
lean-back and lean-forward interaction - For use when your television system lacks a
built-in back channel (return channel). - Relies on PC connected to the Internet or mobile
phone servers to interact with the TV, hence the
two screens - When multiple media devices are used, it is known
as Media multitasking, which is a type of
coactivity - Growing desire for this interaction
- Young markets are the most accepting
12One Screen iTV
- The programs interactive enhancements are
accessible using your TV system. - Interactivity is supplied by the manipulation of
the API of the particular software - Installed on a set-top box - a type of computer
that processes digital information. Can act as a
gateway between your TV or PC and your telephone,
satellite, terrestrial, or cable feed (I/O
signal.)Â - Referred to as middleware because of its
intermediary position in the operating
environment - Software programs are then broadcast to the
set-top box - The box can load and execute the applications
13Internet TV
- The Internet is inherently interactive
(lean-forward) - Can search for videos, TV shows, etc. to download
(legality?) - BitTorrent
- YouTube
- Until interactive TV becomes more mainstream,
this may be a good option.
