  • Patent number: 11711585
    Abstract: A mobile terminal has a communication processing unit that transmits, to a video display apparatus for displaying a broadcasted video content, a request for setting a viewing schedule of the video content. A storage unit stores a starting time of the video content for which the setting of the viewing schedule has been requested; and an information provision unit provides information to a user of the mobile terminal. A control unit determines whether the video display apparatus is existent around the mobile terminal. At a first predetermined time before the starting time, the information provision unit notifies the user of the first predetermined time. If the video display apparatus is not existent around the mobile terminal at a second predetermined time before the starting time, the information provision unit then notifies the user that it is the second predetermined time before the starting time.
