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.

Abstract: A video display apparatus includes: a tone mapping processor that converts, by using dynamic metadata indicating a maximum luminance of a video in each of a plurality of time intervals included in a predetermined period, a luminance of the video in each time interval based on conversion characteristics according to the maximum luminance of the video in the time interval; and a display. The tone mapping processor switches between: a first operation of performing the tone mapping process by using first dynamic metadata that indicates the maximum luminance that is constant over the plurality of time intervals, the first dynamic metadata being generated by using static metadata that indicates a maximum luminance of the video in the predetermined period; and a second operation of performing the tone mapping process by using second dynamic metadata in which the maximum luminance varies over the plurality of time intervals.

Abstract: An information processing apparatus includes: a speech obtainer which obtains speech of a user; a first controller which, when the first controller recognizes that the speech obtained by the speech obtainer is a first activation word, outputs a speech signal corresponding to the first activation word; and a second controller. In the first speech transmission process in which the speech signal of the speech obtained by speech obtainer is transmitted to the VPA cloud server, the first controller determines whether to output a speech signal corresponding to a second activation word to the second controller based on a predetermined priority level when the first controller recognizes that the speech obtained by the speech obtainer indicates the second activation word for causing the second controller to start a second speech transmission process.
