Google Video Search
Seems like an interesting idea:
The Goog tube
Google's project for TV search is ultra-secretive; only a handful of broadcast executives have seen it demonstrated so far. To build the service, the company is recording live TV shows and indexing the related closed-caption text of the programming. It uses the text to identify themes, concepts and relevant keywords for video so they can be triggers for searching.
The software allows people to type in keywords, such as "Jon Stewart," to retrieve video clips of the comedian's TV appearances, marked with a thumbnail picture with some captioning text, for example. Refining the search results for the show "Crossfire" would display a page that looks similar to a film reel, with various still images paired with excerpts of closed captioned text of the now-infamous fight between Stewart and CNN's "Crossfire" hosts. The searcher could click on and watch a specific segment of the show
Google has approached broadcasters to determine business models so that it does not incite copyright lawsuits from rights holders. Google itself can pair relevant advertisements next to video search results. But a broadcaster may wish to use search to drive sales for DVDs, subscription-content services or to sell advertising that would run before and after the video rolls.
