Abstract
In one example embodiment, a program navigation system involves a television (TV) set (or other audio/visual presentation device) and a mobile device. While the TV set is playing an audio/visual program, a keyword recognition module may extract keywords from textual data associated with the program. The textual data may include textual words that match words spoken in the program. Time markers for the keywords may also be saved. A time marker may indicate a play time within the program for the corresponding keyword. The TV set may automatically transmit the keywords to the mobile device, and the mobile device may automatically display the keywords in a user interface. A user may then select one of the keywords. In response, the mobile device may automatically cause the TV set to jump to a portion of the program containing the selected keyword. Other embodiments are described and claimed.
