1. A system, comprising:
a communication interface; and
a processor coupled to the communication interface and configured to:
receive a content feed via the communication interface, the content feed comprising a representation of an event;
generate a content stream comprising or derived from the content feed and a synchronization signal that associates each of a plurality of portions of the content stream with a corresponding real-world time at the event depicted in the content stream, wherein the synchronization signal includes an audio signal at a frequency not associated with human hearing; and
provide the content stream and the synchronization signal to a location via the communication interface;
wherein:
a synchronization master at the location is configured to broadcast the synchronization signal locally; and
each of a plurality of devices at the location is configured to:
communicate with the processor via a first channel to receive the content stream;
communicate with the synchronization master via a second channel different from the first channel to receive the synchronization signal; and
use the synchronization signal to render the content stream such that the content stream presented on a respective device of the plurality of devices is synchronized with one or more other of the plurality of devices.
