Closed Loop Captioning and Search - Google TV!!

( Via Nathan Weinberg in Inside Google ) A nice paper jointly written by several people at Google, including co-founder and whizkid - Sergey Brin. These outlines an approach to relate text articles and television newsitems. Texts are used in close captions to attempt associating news articles on the same event or topic. It's not a recommendation system -- they're finding other writeups of the same story, not different but relevant stories -- but it's still makes a good reading. Google is looking at ways to match television, which it says has a "passive nature", with additional, more detailed information. Two current applications that can benefit from this technology are listed:
-The Intercast system, developed by Intel, allows entire HTML pages to be broadcast in unused portions of the TV signal. A user watching TV on a computer with a compatible TV tuner card can then view these pages, even without an Internet connection. NBC transmitted pages via Intercast during their coverage of the 1996 Summer Olympics.

-The Interactive TV Links system, developed by VITAC (a closed captioning company) and WebTV (now a division of Microsoft), broadcasts URLs in an alternative data channel interleaved with closed caption data [17, 2]. When a WebTV box detects one of these URLs, it displays an icon on the screen; if the user chooses to view the page, the WebTV box fetches it over the Internet.

Google is looking to get itself on your TV. HDTV allows for a lot of interaction and connectivity, be it with the internet, your computer, or just data over the airwaves. If Google can take its technology and make it available for free to TV companies, those companies will probably just dump it in. Google will get its logo on TVs, and can leverage its search engine, and thus AdWords, in relation to TV content. That's the benefit to Google.
