A receiving device, comprising: a communication data processing unit configured to execute an analysis process for received data from a transmitting device; and an output data control unit configured to execute an output control process for the received data from the transmitting device, wherein the communication data processing unit is configured to receive an emergency information delivery notification transmitted by the transmitting device, and to generate event notification data, and wherein the output data control unit is configured to acquire the event notification data, wherein, if the emergency information delivery notification is an on-screen message type emergency information delivery notification notifying that the emergency information is overlaid on a transmission image of the transmitting device, the communication data processing unit is configured to generate the event notification data such that the event notification data indicate that the emergency information delivery notification is the on-screen message type emergency information delivery notification, and wherein, if the event notification data indicate that the emergency information delivery notification is the on-screen message type emergency information delivery notification, the output data control unit is configured to cause output of an application presentation content to a display unit to be stopped and to execute control such that emergency information overlaid on the transmission image of the transmitting device is visible; and wherein, if the emergency information delivery notification is a signaling data application type emergency information delivery notification notifying that the emergency information is delivered by signaling data transmitted from the transmitting device, the communication data processing unit is configured to generate the event notification data such that the event notification data indicate that the emergency information delivery notification is the signaling data application type emergency information delivery notification, and wherein, if the event notification data indicate that the emergency information delivery notification is the signaling data application type emergency information delivery notification, the output data control unit is configured to perform either a process of outputting emergency information included in the event notification data to a display unit or a process of outputting emergency information acquired using emergency information access information included in the event notification data to the display unit. a communication data processing unit configured to execute an analysis process for received data from a transmitting device; and an output data control unit configured to execute an output control process for the received data from the transmitting device, wherein the communication data processing unit is configured to receive an emergency information delivery notification transmitted by the transmitting device, and to generate event notification data, and wherein the output data control unit is configured to acquire the event notification data, wherein, if the emergency information delivery notification is an on-screen message type emergency information delivery notification notifying that the emergency information is overlaid on a transmission image of the transmitting device, the communication data processing unit is configured to generate the event notification data such that the event notification data indicate that the emergency information delivery notification is the on-screen message type emergency information delivery notification, and wherein, if the event notification data indicate that the emergency information delivery notification is the on-screen message type emergency information delivery notification, the output data control unit is configured to cause output of an application presentation content to a display unit to be stopped and to execute control such that emergency information overlaid on the transmission image of the transmitting device is visible; and wherein, if the emergency information delivery notification is a signaling data application type emergency information delivery notification notifying that the emergency information is delivered by signaling data transmitted from the transmitting device, the communication data processing unit is configured to generate the event notification data such that the event notification data indicate that the emergency information delivery notification is the signaling data application type emergency information delivery notification, and wherein, if the event notification data indicate that the emergency information delivery notification is the signaling data application type emergency information delivery notification, the output data control unit is configured to perform either a process of outputting emergency information included in the event notification data to a display unit or a process of outputting emergency information acquired using emergency information access information included in the event notification data to the display unit.
