Content-based Indexing of Captioned Video on the Viewstation
نویسندگان
چکیده
We have designed and constructed a mechanism for using caption text from broadcast television programs to analyze their content. In this paper, we describe the method by which captions are captured and translated from the raw video signal into text on the ViewStation. We also describe our Caption Parser, which analyzes the text and extracts information about the content of broadcast television programs. A specialized version of the parser is used by our Joke Markup program to index captioned monologues of late-night talk shows. The output of the markup program can be viewed through our Joke Browser, enabling selection and replay of jokes based on their content.
