Defining Interactive TV

October 14th, 2009 - Park Associates projects that by 2014, U.S. addressable, interactive TV advertising revenue will exceed $4 billion.

October, 2009 - The CEO of Comcast said in a recent earnings call that 25 million U.S. cable-enabled homes will have access to interactive TV by the end of 2009. Combine this with the 30 million satellite and IPTV subscribers who already receive interactive TV and there will be 55 million households that will be able to access  interactive TV {by the end of 2009}. 

Interactive Television - (May also be known as: ITV, iTV, i-TV, ETV, eTV, Enhanced Television, Enhanced TV, Transactional Television, Fully Interactive TV, Interactive Digital Television, Interactive TV, Web-based Interactive TV, Social Interactive TV, Smart Interactive Television, Two-way Television, Synchronous Programming, Digital Interactive TV/Broadband IP Convergence, Interactive Cable, Interactive Video, Enriched TV, Enhanced Broadcasting, Advanced Interactive TV, TVs with Interactive Programming, Total ITV, Fully Interactive Television, Fully Interactive TV, Advanced TV, Multiplexed TV viewing, Full-service Integrated Interactive TV, Customized, Individualized or Personalized TV {used more often in Europe;} Real-time Companion Programming, ActiveTV.  Looser but at least substantial association with: Web TV, WEB Enhanced TV, Internet TV, Internet Television, Interactive Mobile TV, Individualized Viewing, Net TV, Online TV, Internet on TV, Web-over Television Services, Web-accessed TV, TeleWeb, TV-based Web Browsing, TV Based Browsing, TV Internet System, TV Internet Access Device, Web-over-TV, TV Mail, Web Enhanced TV, Internet Protocol Multicasting, IP Multicast, BusinessTV, Videoconferencing {videophone}, Web PCs, Web Phones, Phone-based Web Boxes, Set-top Browsers, Public Access Internet T, Internet HDTV, IP-based Interactive TV Applications, Interactive TV Widgets.)

A major problem interactive television has had, at least in the States, is that after a particular type of interactive TV technology, such as timeshifting (DVR use) or Video on Demand, becomes at least somewhat successful, journalists, analysts and often even industry professionals seem to spin it off into it’s own separate category of television technology, thus making it in many people’s minds no longer directly associated with interactive television. I remember in 1999 when Video on Demand and DVR use, (timeshifting) were struggling to gain acceptance, these were regularly referred to as interactive television, then those two technologies became successful and so long amigo. With so many interactive television technologies being spun off into their own technology categories, it makes it tougher for interactive television in the States (because interactive television has been successful for many years in other parts of the world) to beat its checkered American past.

Many think that the incorporation of WiFi connectivity will greatly aid in interactive television deployment. In the late 1990s, interactive television had trouble taking off, not only because of the economic roadblock of the 2000 NASDAQ downturn but due to logistics. At that time interactive television applications typically needed to be compatible with many different types of set-top boxes, network operators, types of middleware, headend technologies, etc. WiFi integration into TV sets however can move a good deal of that burden off those often incompatible and proprietary technologies.

Utilization of the Internet also aids in interactive television deployment due to its ability to be a cross platform technology.

The term "ITV (iTV)" has gotten popular. The British TV station ITV utilized the word "ITV". Apple TV is expected to be re-branded as "iTV", Monster Cable produces an iPod video accessory known as the iTV Link and Comcast offers a interactive television service branded iTV. Also for years TThe Interactive TV Dictionary and Business Index™x™ has been trademarked.

Web-enabled TV Widgets - Web-enabled TV Widgets are small, self-contained programs that can be plugged into a web application. 

iTV 2.0

Gesture Recognition - Controlling devices such as TVs and video games primarily with hand and/or finger movement. With this technology you can change television channels, adjust the volume, interact etc. Also see Air Mouse.

CI+ Specification - A standard for enabling interactive applications in smart card modules and more.

Advanced Remote Control Devices


Note, there can be differences between Enhanced TV and Interactive TV. Also note that IPTV can offer great interactive TV but it is not a synonym for Interactive TV.

(1) This first general definition of Interactive TV is for those who define Interactive Television as the top level umbrella definition for all types of interactivity involving televisions, as well as television programming viewed using other interactive mediums, such as the mobile phone and PC. (Note that the web is interactive thus when interactive features are available on a website offering video, technically that's interactive television.) Thus Video on Demand (VOD) would be a subset of Interactive Television and because of that VOD could be entitled either Video on Demand and/or Interactive Television.  The same is true of Internet TV (Broadband TV), Personal TV, etc.

For interactivity, interactive voice response (IVR), Point and Click Devices and/or 3D Gesture Recognition may be used instead of, or in addition to your remote control/keypad.

Interactive Television is TV programming with interactive content and/or enhancements. Interactive TV provides a richer and more efficient television experience. It can combine Traditional TV viewing with a back channel (return path), thus offering the interactivity enjoyed by those communicating through a network, such as the Internet. Interactive TV programming can include interactive advertising, electronic storefronts, electronic communication with others, richer graphics and links to Web (or web-like) sites such as walled gardens. With developments including the incorporation of a digital TVDigital Video Recorders, Video-on-Demand, Electronic Program Guides, etc., interactive TV will continue to become more commonplace. Interactive TV’s future looks great as research conclusively shows that people want additional information and enhancements pertaining to TV programming. Also telcos need to better compete with cable providers who are now offering bundled telephone, TV and Internet service. Interactive IPTV can offer a great deal of interactivity at little extra cost.

Various General Types of Interactive Television:
(Last updated in 2011)

(A) 2-screen Interactive TV where you interact with the TV programming on a "screen" other than the TV. So you'd be watching the television but interacting using personal computers, media centers, phone (or other electronic devices such as PDAs). Text messaging is very popular when the phone is used.

(B) Single-screen Interactive TV  - When the program’s interactive enhancements are accessible using your set-top box, TV system etc.

(C) Internet TV (Broadband TV) - (Interactive Television over the Internet) - The Internet/web is inherently interactive and as long as interactive television in the United States and elsewhere is hampered by incompatible delivery systems and/or receivers, Interactive Television over the Internet has become attractive.

Things you can do with Interactive TV include:

1. The program credits could be available anytime during the show instead of only at the beginning and/or end.
2. At anytime find out who an actor/actress is that you're watching and more information about him/her.

(2) (Maybe known as Interactive Video) - Many consider “Interactive Television” not to be an umbrella term for all interactivity using the Television, but instead just one of many different ways of experiencing interactivity via a television.  Thus, Interactive Television would be a separate subset, while Timeshifting (Personal TV) would be a separate subset (and thus not called Interactive Television,) as would be the case with Internet TV, Video-on-Demand, etc. This definition is more literal and often used.


Interactive Television Further Defined

A communication theory called the Effects Theory proposes that viewers are passive and television directs them.  Some question how many viewers will want to do nothing more than change channels and program their VCR/DVR. But after experiencing the fuller iTV experience, most change their minds. Interactive TV is simply a much more efficient way to watch TV, and it offers so much more. 

Many expect television's longer term future to be Internet TV and the countless millions of channels it could offer, including people's own personal channels. Imagine, you want to watch a particular actor/actress, or a type of programming theme, lets say car crashes, you enter that into your video search engine and it comes up with shows and/or video clips concerning that subject. Probably you would have already pre-programmed your Digital Video Recorder (DVR) or computer to have searched for and recorded on it's hard drive, that particular type of programming. Your DVR or computer could of course check regularly, automatically seeing if any new related programming is available, recording it and alerting you. With the convergence of broadband and a mandated digital TV infrastructure, the possibilities are extreme.

The television is more associated with relaxed viewing (“sitting-back" or "leaning back”) while the PC is more associated with working, ("sitting-up" or "leaning forward”). The argument is that most would rather sit back in a comfortable chair and watch video on a television screen rather than watch video on any other electronic device including a PC. Also watching a television can be more of a social event, a better homogenizer for couples and the home. Many electronic devices aid in transferring content from the Internet to the TV. See Media Extenders.

In Europe, folks have had interactive TV for some time, much of that previously having been in the form of Teletext. This is one reason that Europe, particularly Great Britain, has adopted Interactive Television faster than the States. Still Americans may be surprised at how much Interactive TV is already available and how much more is on the horizon.

Current and future iTV in your area will include Electronic Program Guides, Web-page-style screens, Electronic Storefronts, Information Tickers, Walled Gardens, Polls, Interactive Advertising and a lot more.
