  3. Interactive TV • TV and the Internet are each recognized as “a technology …that seems to change everything” (BW, Oct 4 ‘99) • Interactive TV is the convergence of TV and the Internet • Profound impact on Electronic Commerce expected • WebTV: 1 million subscribers, 350 hrs/wk of programming • AOLTV: projected 2 million subscribers in 2 years • ITL partnering to develop the standards required for the success of Interactive TV

  4. Interactive TV Traditionally separate media are converging: • Wireless phones do email • Internet does broadcast radio and TV • Broadcast TV references links to Web pages

  5. TV: } (non-interactive) accessed separately OR Web: (interactive) With DASE/DDE, TV and Web are converging into a single medium: DASE/DDE Interactive TV Currently, for the viewer:

  6. Interactive TV Demonstration: • An industry plan for an interactive TV application • Developed here as a prototype for how EC applications using DASE and DDE might appear • EC application Web pages to use XML

  7. Golf matches on TV Web site with associated products DASE/DDE: single medium DASE/DDE Interactive TV Demonstration Current production:

  8. } Viewing experience dramatically enhanced: viewer becomes an active participant } E-commerce dramatically enhanced by enabling purchases from the comfort of one’s easy chair Interactive TV Viewing Experience

  9. Interactive TV Genres most amenable to interactivity: • News • Sports • Documentaries • How-to • Game

  10. Interactive TV Types of interactive enhancements: • chat • email • backstory (prev. episodes, background on a story, behind the scenes) • buy stuff • story so far • more like/about this • story participation • story enhancement

  11. Interactive TV Story Participation Winkey Dink and You (1953-1957)

  12. Interactive TV Fundamental Convergence Question: • How are two separate media synchronized?

  13. Interactive TV Synchronization Examples: Enhanced TV • Sunday and Monday Night Football • player/team information relevant to each play • interactive game: “choose the ballcarryer” • request player/team statistics • “Who Wants to be a Millionaire” • play along with the game • special bonus questions • audience polls • No special receiver required • Broadcast/Internet synchronization done by production team • Open connections to Web servers maintained

  14. Interactive TV Game Participation

  15. Interactive TV Synchronization Example: DDE (ATVEF: WebTV Plus) • Wheel of Fortune, Jeopardy, MSBNC, Twenty One (among others) • Play along with the game in the broadcast • Requires a WebTV receiver • Web page references sent in the VBI of broadcast processed by receiver
