Abstract:
A broadcast data receiving section receives broadcasted broadcast data. A reception confirmation key extracting section extracts reception confirmation keys from the broadcast data. A reception confirmation processing section counts the extracted reception confirmation keys. A viewing determination section determines that a viewer has watched a program when the thus counted number of reception confirmation keys exceeds a reference value. This makes it possible to more accurately determine whether the viewer has watched the program.
