Synchronizing multiple transmissions of content

摘要

The disclosure relates generally to providing synchronized supplemental content. In one aspect, second user devices may be used to consume supplemental content associated with primary content presented on a first display. The supplemental content may be synchronized with the primary content. Such synchronization may be performed by detecting and reporting triggers within the primary content and transmitting synchronization signals to appropriate second user devices. Another aspect of the disclosure relates to determining which interfaces or applications will report the triggers, and fine-tuning how many interfaces or applications will report the triggers.

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.
