Title: Interactive Television iTV


1
Interactive Television - iTV
  • Current and future applications
  • of iTV and usability issues
  • Michelle Marguth

2
What 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.

3
Types of TV interactivity
  • Interactivity with a TV set
  • Interactivity with TV program content
  • Interactivity with TV-related content

4
Interactivity 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.

5
Apple 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

Interactivity 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

Interactivity 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)

TV-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.

Interactivity 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

10
Physical Types of User Interactions
  • Two-screen iTV
  • Single-screen iTV
  • Internet TV (Broadband TV)

11
Two-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

12
One 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.) 
  • 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

13
Internet 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.
