Abstract
A synchronization manager synchronizes multiple media streams. The synchronization manager queries a media stream output device associated with each media stream to synchronize, and in response receives the current device clock time of each device, each device's next available media stream output time, and each device's delta between available media stream output times. The synchronization manager uses this timing information to determine an earliest available media stream output time common to each media stream output device, and synchronizes the output of the media streams by providing each stream to its associated output device at the earliest available common output time.
