Abstract: ABSTRACT SYNCHRONIZED MULTICAST ADVERTISEMENT PLAYBACK SYSTEM AND METHOD A synchronized multicast advertisement playback system (100) comprises a multicast controller (110) configured to publish metadata comprising media URLs, content identifiers, and campaign grouping information associated with advertisement content via a publish-subscribe messaging protocol, and a plurality of display devices (120) communicatively coupled to the multicast controller (110). Each display device (120) retrieves and caches the advertisement content based on the metadata and synchronizes an internal clock with a reference clock source. The multicast controller (110) publishes the metadata to a first messaging topic (112), receives buffer-ready acknowledgements from the display devices (120), and publishes an activation control message comprising an activation timestamp to a second messaging topic (114). Each display device (120) subscribes to the first messaging topic (112) and the second messaging topic (114), transmits a buffer-ready acknowledgement upon caching, and initiates playback when the internal clock reaches the activation timestamp.
