1. A video display device comprising:
a tuner configured to receive a digital broadcast signal;
first interface circuitry configured to communicate with an external device;
second interface circuitry configured to communicate with a smart phone through a network;
a display configured to display a video;
a memory configured to store a program; and
a processor, when executing the program, configured to, when detecting information showing that the external device is connected to the first interface circuitry, or information showing that the external device connected via the first interface circuitry is turned on, transmit, to the smart phone via the second interface circuitry, information for initiating an application software on the smart phone so as to cause the application software to display, on a display of the smart phone, an operation screen for accepting a remote operation instruction to the external device.
