Abstract
Audio-visual synchronization using retrieval of visual data through a network to enhance the content presented to the user and to provide the user with a more meaningful and engaging audio-visual experience. An audio player such as an electronic book reader or stereo plays an audio file. The audio file, whether in analog form as played through a speaker or in digital form, is provided to a controller, which scans the audio file to detect a trigger or cue identifying visual data stored in a data store or database that is local or accessible through a network. The controller accesses the data store or database, downloads the pre-determined visual data, and controls the audio player and display such that playing of audio data and display of the retrieved visual data are synchronized with each other.
