Abstract: A cable assembly includes a cable, a connector that is provided at an end of the cable in a direction in which the cable extends, a plurality of electric transmission lines configured to transmit an electric signal, and a plurality of optical transmission lines configured to transmit an optical signal. The plurality of electric transmission lines and the plurality of optical transmission lines are provided in the cable assembly so as to extend across the cable and the connector. The plurality of optical transmission lines are provided so that at least one of the plurality of optical transmission lines is provided at each of ends of the cable assembly in a width direction perpendicular to the direction in which the cable extends. The plurality of electric transmission lines are provided inside the plurality of optical transmission lines in the width direction.

Abstract: A video display device includes: a video receiver that obtains video data including a video and dynamic luminance characteristics indicating a time-dependent change in luminance characteristics of the video; a tone mapping processor that, in the case where a luminance region having a luminance less than or equal to a first luminance is defined as a low luminance region, and a luminance region having a luminance exceeding the first luminance is defined as a high luminance region, (i) performs first tone mapping using first conversion characteristics when first luminance characteristics exceed a predetermined threshold value, and (ii) performs second tone mapping using second conversion characteristics when the first luminance characteristics are less than or equal to the predetermined threshold value.

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: There is provided a reproduction device that outputs a video signal to a display device via predetermined communication, the video signal including a video having pictures and corresponding pieces of image characteristic information. The reproduction device includes: an obtaining unit that obtains a first time difference between a timing at which the display device displays one picture among the pictures and a timing used by the display device to display one of the pieces of image characteristic information corresponding to the one picture; an adjuster that adjusts at least one of a timing at which the pictures are outputted and a timing at which the pieces of image characteristic information are outputted to reduce the first time difference; and an output unit that outputs the pictures and the pieces of image characteristic information via the predetermined communication at the time adjusted by the adjuster.
