Abstract
Primary digital content played on a media device, such as a television, handheld device, smart phone, computer, or other device, is sampled and data is derived from the sample for identification of the primary digital content. Automatic content recognition is performed to determine the primary digital content. The time of the sample may also be determined. Supplementary digital content is then selected and transmitted to the media device, or to another device, based upon the identified primary digital content. The supplementary digital content may be adapted in layout, type, length, or other manners, based upon the platform and/or configuration of the media device or any other device to which the supplementary digital content is transmitted.
