Abstract:
1. A method of providing access to information of potential interest to a user of an electronic device, comprising the steps of: while content is being displayed on the device, periodically updating a first word buffer with words extracted from closed captioning information corresponding to the content since a beginning of a program or story, and periodically updating a second word buffer with words extracted from closed captioning information corresponding to the content based on a most recent n seconds, wherein n is a preset value, such that the second word buffer maintains keywords only present in the closed captioning information during the last n seconds of time; monitoring the user interaction with the device to identify when the user provides user input indicating an interest in learning more information about content currently being displayed on the electronic device; wherein said device comprises a TV; wherein said monitoring further includes monitoring user interaction with the TV; extracting keywords from the second word buffer based on frequency of appearances of words in the first word buffer by analyzing the closed-caption information provided to the user via the TV currently stored in the first and the second word buffers; converting the extracted keywords into a foreign language; determining key information, includes supplementing the extracted keywords with keywords related to contextual information about the content of a channel being watched, based on the extracted keywords when the user input indicating the interest is identified; and searching available sources for information of potential interest to the user based on said key information.
