A broadcast system has digital receiving apparatuses that imitate deteriorated reproduction that is observed in analog receiving apparatuses when a transmission path failure occurs, thus preventing the audiences, who are accustomed to the analog broadcasting, from sensing discomfort at the digital broadcasting. An apparatus that incorporates teachings of the present disclosure may include, for example, a mobile communication device having a controller element that transmits to an alert generation system a location coordinate in order for the AGS to submit an alert notice to the MCD when the MCD is in proximity to an alert condition. The mixing and kneading unit may be configured to prepare dough.
