A receiving device that receives contents broadcasted via a broadcasting network, the device comprising: an application executing unit configured to execute a link application linked with the received contents; and an application control unit configured to control the application executing unit based on application control information (50, 100) on the link application, wherein the application control information (50, 100) includes at least an application boundary indicating a range of web pages to which the corresponding link application can be switched, and permission information showing the presence or absence of access permission from the link application to a broadcasting resource for each receiving device control function and indicating permission or prohibition of a predetermined action for the link application, and the application control unit is further configured to - give, to the link application, the access permission included in the permission information for access to the broadcasting resource, the access permission being given within the range indicated by the application boundary for each receiving device control function, - analyze the action of the link application by acquiring the application control information from the broadcasting network and determining whether an action of the link application found in the data contents of the link application agrees with the contents permitted in the application control information (50, 100) prior to start of the link application by the application executing unit, and - control the application executing unit based on comparison between the action and the permission information to limit the start of the link application. an application executing unit configured to execute a link application linked with the received contents; and an application control unit configured to control the application executing unit based on application control information (50, 100) on the link application, wherein the application control information (50, 100) includes at least an application boundary indicating a range of web pages to which the corresponding link application can be switched, and permission information showing the presence or absence of access permission from the link application to a broadcasting resource for each receiving device control function and indicating permission or prohibition of a predetermined action for the link application, and the application control unit is further configured to - give, to the link application, the access permission included in the permission information for access to the broadcasting resource, the access permission being given within the range indicated by the application boundary for each receiving device control function, - analyze the action of the link application by acquiring the application control information from the broadcasting network and determining whether an action of the link application found in the data contents of the link application agrees with the contents permitted in the application control information (50, 100) prior to start of the link application by the application executing unit, and - control the application executing unit based on comparison between the action and the permission information to limit the start of the link application. - give, to the link application, the access permission included in the permission information for access to the broadcasting resource, the access permission being given within the range indicated by the application boundary for each receiving device control function, - analyze the action of the link application by acquiring the application control information from the broadcasting network and determining whether an action of the link application found in the data contents of the link application agrees with the contents permitted in the application control information (50, 100) prior to start of the link application by the application executing unit, and - control the application executing unit based on comparison between the action and the permission information to limit the start of the link application.
