Claim:
1. A method comprising: transmitting, by a computing device and to a plurality of interfaces, sampling information; receiving, by the computing device and from a first subset of the plurality of interfaces, one or more trigger detection signals indicating receipt of a particular trigger at the first subset of the plurality of interfaces, the first subset of the plurality of interfaces being determined based on the sampling information; generating, by the computing device, a synchronization signal based on the one or more trigger detection signals; transmitting, by the computing device, to a plurality of second devices, and to cause the plurality of second devices to output supplemental content in synchronization with content being output by a plurality of first devices, respectively, the synchronization signal; and transmitting an adjustment value to the plurality of interfaces to cause the plurality of interfaces to adjust the sampling information.
