Abstract
A receiving unitrepeatedly receives a transport stream, and a specifying unitspecifies a purchase state. A restoring unitgenerates a first audio-digital (AV) signal and interactive data, and an AV reproducing unitgenerates a second AV signal. A combining unit 106 generates a data-AV combined signal by combining the generated second AV signal and a data signal generated from the interactive data. A data presentation restricting unitoutputs the interactive data and a purchase state signal. A control unitreceives an operation signal from an inputting unitand outputs it to a data operation restricting unitA data analyzing unitanalyzes a presentation element contained in the interactive data and generates video data, which is the data signal. A data judging unitjudges whether a currently-presented presentation element is included in the same group as a presentation element that is a link destination of the presented presentation element. When the purchase state is a viewing permitted state, the data operation restricting unitoutputs the operation signal. When the purchase state is a preview state or viewing prohibited state and when the above two presentation elements are included in the same group, the operation restricting unitalso outputs the operation signal.
