Provided is a display method of displaying, on a display device, video of video data where luminance of video is defined by a first EOTF indicating a correlation of HDR luminance and code values. The method includes: acquiring the video data; performing, regarding each of multiple pixels making up the video in the acquired video data, first determining of determining whether luminance of that pixel exceeds a first predetermined luminance; performing, regarding each of the multiple pixels, dual tone mapping where luminance of that pixel is reduced by a different format in a case of the luminance of the pixel being found to exceed the first predetermined luminance from the first determining, and a case of the luminance of the pixel being found to be equal to or lower than the first predetermined luminance; and displaying the video on the display device using the results of the dual tone mapping.

Provided is a display method of displaying, on a display device, video of video data where luminance of video is defined by a first EOTF corresponding to HDR. The method includes: acquiring the video data; performing first conversion where the luminance of the video is converted to a luminance corresponding to a dynamic range of a third EOTF, where, with regard to a second EOTF that is part of the first EOTF and is the part of a luminance range where the peak luminance indicated by the peak luminance information included in the acquired video data is maximum luminance, the dynamic range of luminance of the second EOTF is reduced with maximum luminance of the second EOTF matching displayable luminance of the display device, while maintaining the relative relationship of luminance of the second EOTF; and displaying the video on the display device using the result of the first conversion.

In a method for monitoring power, preset information that defines periods in which one or more preset electric devices are scheduled to operate is received, an amount of power available, which is an estimated amount of power available in the building in each period, is calculated, estimated power consumption, which is estimated power consumption in the building in each period, is calculated using power consumption information, to which power consumption of the electric devices to be preset is registered in advance, and the preset information, an alternative instruction with which the estimated power consumption becomes lower than or equal to the amount of power available is generated, and the alternative instruction is displayed on a terminal apparatus. And at least one of the receiving, the calculating the amount of power available, the calculating the estimated power consumption, the generating and the displaying is performed by a processor.

Provided is an information output method that outputs information when swapping a secondary battery for powering a vehicle. The information output method includes comparing a rank related to the performance of a first battery unit (battery unit A) on board a vehicle to a rank related to the performance of a second battery unit (battery unit B) that is installable in the vehicle in place of the first battery unit, and outputting output information according to a result of the comparison in the comparing step.

Disclosed is a method for controlling a cordless telephone device for use in a system that allows remote control of a home electric appliance. The method includes a first generation step of causing a first generation unit in a handset to encode audio input via a sound receiving unit in the handset to generate a first stream, and a first transmission step of transmitting the first stream to a base unit. The first generation step includes causing the first generation unit to generate instruction bit information and a first instruction stream when a first trigger indicating a request to start the remote control is given to the first generation unit. The first transmission step includes transmitting the instruction bit information and the first instruction stream to the base unit through a multiplexing scheme that is common to transmission of a first stream generated when the first trigger is not given.
