Abstract
Embodiments provide techniques for distributing supplemental content based on content entities within video content. Embodiments include receiving video data containing an embedded watermark at a first position within the video data. The embedded watermark is detected at the first position within the video data. Embodiments also include transmitting, to a remote content server, a message specifying a time stamp corresponding to the first position within the video data. In response to transmitting the message, supplemental content corresponding to a content entity depicted within the video content at the first position within the video content is received from the remote content server. Embodiments also include outputting the video data for display together with at least an indication of the supplemental content.
