eTV - Applications

What does it look like? - How does it work? - What systems support eTV?

Program providers can provide enhanced content through single screen or dual screen applications.

Research has also identified types of relationships that program providers have with their audience.

Technically, one can categorize types of enhanced services according to:

  • Method of delivery (Terrestrial, Satellite, Cable, Telco/IP)
  • Software & hardware (STB, cable modems, IRD etc)
  • Method (if any) of sending information back from the viewer

Two-screen and single-screen applications

  • Two-screen systems refer to a TV and a computer monitor of a computer connected to the Internet.
  • Single-screen systems rely on set-top-boxes or other decoders that can superimpose information directly on top of a television display.

A major advantage of two-screen systems is the huge base of potential users- households with televisions and computers with Internet access in the same room. People who surf the Web while watching TV (sometimes called “telewebbers” - News.com 2000).

Households with PCs in the same room as television sets:

  • 2001 - 20 million
  • 2002 - 30-40 million
    • Compared to 10 million homes with interactive-capable satellite or cable service. (USA Today 2002)
