BBC working to integrate web and TV content

Via Newslab, the BBC is working on a way to integrate web content with TV programming using closed captioning and keywords.

“The most useful application we could think of was something that would provide web content that was relevant to what was being talked about on TV,” writes Andrew Littledale of the BBC. The app uses the closed caption feed to produce a list of “relevant concepts” that pops up on screen. Those concepts are mapped to related content on the BBC website, so users can click through to read more about any topic that interests them.
