Abstract: A video display apparatus includes: a tone mapping processor that performs a tone mapping process of converting a luminance of a video by using conversion characteristics according to a maximum luminance of the video; and a display that displays the video that has undergone the tone mapping process. The tone mapping processor switches between a first tone mapping process of dynamically changing the conversion characteristics according to a time-dependent change in the maximum luminance of the video and a second tone mapping process that is performed using constant conversion characteristics irrespective of the time-dependent change in the maximum luminance of the video.

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 a second activation word different from the first activation word; and a second controller which performs an activation process for starting transmission of the speech signal of the speech obtained by the speech obtainer to a VPA cloud server when the second controller recognizes that the speech signal output by the first controller indicates the second activation word.

Abstract: A video display system includes: an observation device, a data obtainment unit that obtains data related to a movement direction of the capturing unit, and a metadata composition unit that obtains metadata based on the obtained data; and a VR device including: a reception unit that receives the metadata; an orientation estimation unit that estimates an orientation of the display device; a differential calculation unit that calculates a relative movement direction of the capturing unit based on a difference between the orientation of the display device and the movement direction of the capturing unit in the metadata; a presentation unit that presents the calculated relative movement direction to a user of a display device; a video generation unit that generates a display video; and a VR device including a display device that displays the display video.

Abstract: A video display apparatus includes: a video receiver that acquires video data including a main video; a generator that generates first characteristics information that indicates first dynamic luminance characteristics by using the video data when a luminance dynamic range format of the main video indicated by the video data is different from a display format that indicates a luminance dynamic range format displayable by the video display apparatus, the first dynamic luminance characteristics being dynamic luminance characteristics indicating a time-dependent change in luminance characteristics of the main video and correspond to the display format; a tone mapping processor that performs a tone mapping process of converting a luminance of the main video based on conversion characteristics according to the first dynamic luminance characteristics indicated by the first characteristics information generated by the generator; and a display that displays the main video that has undergone the tone mapping process.
