11. The broadcasting receiver according to claim 1 , wherein

the control portion enables parental control corresponding to a user determined to have entered premises of the user as the prescribed range in a case where the parental control corresponding to the user determined to have entered the premises of the user as the prescribed range is disabled when the determination portion decides that the user to be subject to parental control has entered the premises.

12. The broadcasting receiver according to claim 1 , wherein

the parental control information is stored in association with an age of the user to be subject to parental control, and

the control portion updates the parental control information to correspond to an increased age when the age of the user to be subject to parental control is increased.

13. A parental control system comprising:

a positional information acquisition portion acquiring positional information of a user; and

a broadcasting receiver including a receiving portion receiving a broadcast signal, a determination portion deciding whether or not a user to be subject to parental control of the broadcast signal has entered a prescribed range on the basis of the positional information of the user acquired by the positional information acquisition portion, and a control portion, wherein

the control portion enables parental control corresponding to a user determined to have entered the prescribed range in a case where the parental control corresponding to the user determined to have entered the prescribed range is disabled when the determination portion decides that the user to be subject to the parental control has entered the prescribed range.

the determination portion decides whether or not the user to be subject to parental control has entered the prescribed range on the basis of the positional information of the user to be subject to parental control acquired by an external device with GPS,

the control portion is capable of switching between an on-state and an off-state of GPS and enables the parental control of parental control information in which the parental control is set for each time period, in a case where the parental control is set to be disabled and GPS is set to be the on-state when the determination portion decides that the user to be subject to parental control has entered the prescribed range, and
