Abstract
A method and system for decoupled video and audio data presentation involves determining available data that may be displayed or spoken to a user. An audio portion of the available data and a visual portion of the available data are determined. The audio portion is communicated in an auditory form on an auditory device to a user and a visual indication indicating the presence of the visual portion is communicated to the user. A selection of the visual portion is received in response to the visual indication and a visual device separate from the audio device is determined for displaying the visual portion. In one embodiment, audio data and video data are dynamically synchronized across multiple devices.
