Simultaneously rendering a plurality of digital media streams in a synchronized manner by using a descriptor file

A non-transitory computer-readable storage medium having stored thereon instructions which, when executed by a processor of a computing device, cause the computing device to:

• download a descriptor file for synchronizing a plurality of digital media streams, wherein the plurality of digital media streams each contain digital media content corresponding to a same originating work, wherein the plurality of digital media streams includes a first digital media stream containing a digital audio narration of the originating work and one or more other digital media streams, wherein the one or more other digital media streams include a second digital media stream, and wherein the descriptor file is external to the first digital media stream;
• access the descriptor file to obtain location information for two or more of the plurality of digital media streams, wherein the two or more of the plurality of digital media streams include the second digital media stream;
• access the descriptor file to determine synchronization points in the digital media content of the second digital media stream that correspond to synchronization time offsets in a timeline of the digital audio narration of the first digital media stream;
• and
• simultaneously render the two or more of the plurality of digital media streams in a synchronized manner by correlating the synchronization points and the synchronization time offsets.
