Abstract
Systems and methods of generating a synchronized media content presentation using a plurality of media output systems communicably coupled to a respective plurality of network connected platforms are provided. A first network connected platform receives an IEEE 802.1AS master timing signal generated by “Grand Master” timing circuitry disposed in a second network connected platform. IEEE 802.1AS application service circuitry disposed in the first network connected platform determines an offset between a local timing signal and the receive master timing signal. Talker circuitry disposed in the first network connected platform synchronizes a media content presentation to the master timing signal and communicates a media/master timing signal synchronization signal to each of the network connected platforms. The media/master timing signal synchronization signal includes data representative of a media start location and a media start time referenced to the master timing signal.
