In various embodiments, a content feed comprising a representation of an event is received. 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 are generated. The content stream and the synchronization signal are provided to a location via a communication interface. Each of a plurality of devices at the location is configured to use the synchronization signal to render the content stream in a manner that is synchronized with one or more other of the devices. ## Claims ### Claim 1 A system, comprising: a communication interface;
