Abstract: A conversion method for converting luminance of a video, including a luminance value in a first luminance range, to be displayed on a display apparatus includes: acquiring a first luminance signal indicating a code value obtained by quantization of the luminance value of the video; and converting the code value indicated by the acquired first luminance signal into a second luminance value determined based on a luminance range of the display apparatus, the second luminance value being compatible with a second luminance range with a maximum value smaller than a maximum value of the first luminance range and larger than 100 nit. This provides the conversion method capable of achieving further improvement.

Abstract: In a converting method relating to picture luminance according to one aspect of the present disclosure, the picture luminance is formed by luminance values in a first luminance range. In this method, a first luminance signal that indicates code values obtained by quantizing the luminance value of the picture is obtained, code values, which are associated with the code values indicated by the obtained first luminance signal by quantization for a second luminance range different in a maximum value from the first luminance range are determined as converted code values, and the first luminance signal is converted into a second luminance signal indicating the converted code values. As a result, the converting method is further improved.

Abstract: In a converting method for converting luminance of an input video in order to display the video on a display device, the luminance of the video is a first luminance value in a first luminance range where a maximum luminance value is defined as a first maximum luminance value that exceeds 100 nit. The method includes acquiring a first luminance signal indicating a first luminance value of the video, selecting a luminance converting process to be executed from among a plurality of luminance converting processes based on a reference luminance value corresponding to reference reflectance included in first meta data of the acquired first luminance signal, converting the first luminance value indicated by the acquired first luminance signal into a second luminance value in a second luminance range where a maximum luminance value is defined as a second maximum luminance value that is smaller than the first maximum luminance value and larger than 100 nit based on the selected luminance converting process.

Abstract: A function update method improving household appliance functions by enabling new and existing household appliances to perform cooperative processing. In the method, a server stores registration information listing identification information for each household appliance owned by a user, combination information listing combinations each including household appliances performing cooperative processing, and update information for each household appliance in each combination, for updating a function for performing the cooperative processing. The method includes: receiving, from a household appliance having identification information not listed in the registration information, a request to list the identification information in the registration information, and listing the identification information in the registration information; selecting a combination listed in the combination information, the combination including the household appliance and all other household appliances in the combination being registered in the registration information; and transmitting update information to each household appliance requiring a function update in the combination.

IPC: H04L29/08
Abstract: A device management system includes: a server; base stations for long-distance wireless communication; and a device that communicatively connect to one of the base stations and that each sequentially transmit, to the server via the one base station, operation information indicating the current operation state of the device. Upon sequentially receiving the operation information, each of the base stations sequentially transmits, to the server, unique information unique to the base station together with the sequentially received operation information. The server sequentially receives, and sequentially stores in association with each other, the operation information and the unique information. When first and second unique information received at first and second times, respectively, are different, the server separately manages first operation information received in a first period ending at the first time and second operation information received in a second period starting at the second time.
