Abstract: A video processing system includes: an acquirer that acquires video data including a main video; a format acquirer that acquires a display format that indicates a luminance dynamic range format displayable by a video display apparatus; a generator that generates first characteristics information that indicates first dynamic luminance characteristics that correspond to the display format by using the video data when a luminance dynamic range format of the main video indicated by the video data is different from the display format, the first dynamic luminance characteristics being dynamic luminance characteristics indicating a time-dependent change in luminance characteristics of the main video; and a video transmitter that outputs the first characteristics information generated by the generator.

Abstract: A video display system 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-depend 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-depend change in the maximum luminance of the video. When the tone mapping process used is switched from the second tone mapping process to the first tone mapping process, the conversion characteristics used is changed gradually or stepwise from the constant conversion characteristics to dynamically changing conversion characteristics over a plurality of frames.

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.
