Abstract
Supplementary digital content is provided to be played with primary digital content on a media device, such as a television, handheld device, smart phone, computer, and so forth. The primary digital content is sampled, and the time of the sample is noted. The primary digital content is identified, and the supplementary digital content is selected and transmitted, with an indication of timing for play of the supplementary digital content based upon the sample time. Synchronization of the primary and supplementary digital content playback is based upon reference to the sample time.
