Abstract (en)
[origin: WO2004034755A2] Interacting with broadcast content. A mass media broadcast network communicates broadcast content to multiple recipients. Broadcast receivers present the broadcast content to the recipients. Client computers transmit a query about a selected portion of the broadcast content. Interactive remote controls each operated by a respective recipient transmit a channel control signal to tune a broadcast receiver to a station channel upon which the broadcast content is presented. The controls also receive the query, present the query to a recipient, accept input of a response to the query, and transmit the response to the client computer. Each correct response verifies exposure of the responding recipient to the selected content portion.
