A broadcast audience interaction and feedback system may discover and activate a recording function of a portable device of a user to record audio and/or video of media content output by a media device in proximity to the user. The audio or video data may be used to identify the content by matching audio or video fingerprints or signatures of the data recorded by the portable device with separately generated signatures or fingerprints associated with the content. Additional entities may be automatically associated with the content via capturing of metadata or closed captioning data during the content, OCR of displayed text in the content, or detection of other such entities. In some implementations, the portable device may also capture feedback from the user, including cheering, applause, and laughter, as well as explicit questions or comments, voting choices, etc. The feedback may be identified, and queries generated or additional functions performed based on the identified feedback, the identified media content, and/or one or more entities associated with the identified media content. |
