Abstract
A method for displaying supplemental content with a content stream on a display is provided. A content stream for a program is received, and a portion of the received content stream is sampled. The sampled portion is analyzed to determine a media identifier for the content stream, the media identifier being transmitted to a content server. Supplemental content is retrieved from the content server using the media identifier. And the content stream is rendered on the display with the supplemental content. The supplemental content provides access to an interactive feature, the interactive feature providing internet communication during the receipt of the content stream.
