Abstract
A method is provided in which a descriptor file is created for synchronizing a plurality of digital media streams. A plurality of time offsets are identified in a timeline of a digital audio narration of a first digital media stream, and the plurality of time offsets and a corresponding plurality of content points are stored in the descriptor file in a manner indicating a correlation therebetween. Synchronization points are identified in digital media content of one or more other digital media streams, and synchronization time offsets are selected that correspond to the synchronization points from the plurality of time offsets. The synchronization time offsets and the corresponding synchronization points are stored in the descriptor file in a manner indicating a correlation therebetween, such that the descriptor file allows a synchronized rendering of the plurality of digital media streams on a client device.
