Abstract: Various arrangements for providing interactive content to viewers of television programming are presented. A television service provider system may supplement broadcast television programming with a supplemental audio signal. The supplemental audio signal may not part of the broadcast television programming as received by the television service provider system from a content provider. The television service provider system may broadcast a data stream comprising the broadcast television programming and the supplemental audio signal via a television programming distribution network. A television receiver may receive the data stream and output the broadcast television programming and the supplemental audio signal. A viewer's mobile device may detect the supplemental audio signal using an on-board microphone of the mobile device. In response to the received supplemental audio signal, the mobile device may access interactive content and provide such interactive content to the viewer.
