Abstract
The present invention discloses methods and devices for distributed audio/video (A/V) synchronization and playback. Methods include the steps of: enabling identification of an A/V orchestrator by at least one external A/V system using a data-exchange protocol system; enabling configuration information to be available to at least one external A/V system; identifying A/V data from an A/V source to at least one external A/V system; repetitively synchronizing at least one respective system clock with an orchestra timing on the A/V orchestrator; and repetitively sending at least one synchronization notification to at least one external A/V system, wherein at least one synchronization notification is configured to: indicate a given timing in the orchestra timing during A/V playback, indicate a given position in the A/V data during A/V playback; and instruct at least one external A/V system to move to a currently-playing A/V segment in the A/V data for A/V playback.
