Abstract

In a power-on operation of a receiving device that receives digital broadcasting, when PIN information for setting a parental control function of a download application obtained via a network is set, a video output is turned to an off state during a time period before a download application is received from the power-on until a predetermined time elapses, a download application is executed when the download application is received during the time period from the power-on until the predetermined time elapses, and the setting of the PIN information is cancelled when a download application is not received during the time period from the power-on until the predetermined time elapses.

a PIN information setting cancellation part that, when the PIN information with which the parental control function has been set is held in the PIN information holding part, cancels setting of the PIN information held in the PIN information holding part if a download application cannot be received during the time period from the power-on until the predetermined time elapses.

2. The receiving device according to claim 1, wherein

when the PIN information with which the parental control function has been set is held in the PIN information holding part and if a download application cannot be received during the time period from the power-on until the predetermined time elapses,

the display control part displays a screen for inputting PIN information, and

the PIN information setting cancellation part cancels the setting of the PIN information held in the PIN information holding part when PIN information that is identical with the PIN information held in the PIN information holding part is inputted.

3. A receiving device that receives digital broadcasting, the receiving device comprising:

a memory part that stores a download application obtained via a network and having a parental control function and a built-in application that is installed within the receiving device; and

a mode selection part that selects one of a first mode and a second mode, the first mode being a mode in which, when a download application can be received, the download application is received and executed, and, when a download application cannot be received, the built-in application is executed, and the second mode being a mode in which the built-in application is executed regardless of availability of a download application.

4. The receiving device according to claim 3, comprising:

a PIN information holding part that holds PIN information with which the parental control function of a download application is set, wherein

when the second mode has been selected, the mode selection part displays a screen for inputting PIN information, and sets the second mode when PIN information that is identical with the PIN information held in the PIN information holding part is inputted.

5. A receiving device that receives digital broadcasting, the receiving device comprising:

a memory part that stores a download application obtained via a network and having a parental control function and a built-in application that is installed within the receiving device;

a PIN information holding part that holds PIN information with which the parental control function of a download application is set;

a display control part that, when PIN information with which the parental control function has been set is held in the PIN information holding part, sets a video output to an off state during a time period from power-on until the time when a download application can be received during which an operation is carried out based on the built-in application;

a cable card interface part to which a cable card is detachably attached and that reads a content of a memory area of the cable card; and

a cable card management part that carries out an authenticating operation of the cable card, wherein

the cable card management part cancels, when the cable card is determined to be different from a cable card that has been authenticated last time in the authenticating operation, setting of the PIN information that is held in the PIN information holding part.

6. A receiving program stored in a receiving device that receives digital broadcasting, the receiving program causes a computer to realize:

a function for detecting, in a power-on operation, setting of PIN information with which a parental control function of a download application obtained via a network is set;

a function for, when the PIN information is set, setting a video output to an off state during a time period from the power-on until a predetermined time elapses until the time when a download application can be received;

a function for, when the PIN information is set and if a download application is received during the time period from the power-on until the predetermined time elapses, executing the download application; and

a function for canceling the setting of the PIN information when the PIN information is set and if a download application is not received during the time period from the power-on until the predetermined time elapses.

7. The receiving program according to claim 6, wherein

the function for canceling the setting of the PIN information includes:

a function for displaying a screen for inputting PIN information;

a function for verifying whether or not PIN information that is inputted is identical with PIN information that has previously been set;

a function for unlocking the PIN information if the inputted PIN information is identical with the PIN information that has previously been set, and turning the video output to an on state; and

a function for displaying the screen for inputting PIN information again if the inputted PIN information is different from the PIN information that has previously been set.

8. A receiving program stored in a receiving device that receives digital broadcasting, the receiving program causes a computer to realize:

a function for storing, in a memory part, a download application obtained via a network and having a parental control function and a built-in application that is installed within the receiving device;
