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: A video display system includes: a VR system including a display that displays a VR space to a participant who participates in a VR experience, and an audio processor that receives and outputs voice; an explainer terminal that receives and outputs voice from and to an explainer who provides an explanation to the participant in the VR space; a video distributor that distributes a 360-degree video for the VR space to the VR system; an audio conversation unit that assists an audio conversation between the participant and the explainer; and a controller that manages an operation mode that selectively takes a first state in which questions from the participant to the explainer are not allowed, a second state in which questions are allowed, and a third state in which a question is being asked, and causes the VR system to display information specifying the operation mode on the display.

Abstract: A display device includes: a first closed-bottom lens tube including a first display part on the closed bottom for displaying a first image; a second closed-bottom lens tube including a second display part on the closed bottom for displaying a second image; an adjustment mechanism including a first rod that extends from the first lens tube and a second rod that extends from the second lens tube and is rotatably connected to the first rod; and an image outputter that outputs the first and second images to the first and second display parts, respectively. The image outputter, in accordance with the angle of rotation of the first and second rods of the adjustment mechanism, controls and outputs the first and second images to bring the horizontal directions thereof closer to the arrangement direction of the first and second lens tubes.

Abstract: In a reproduction technique, a video stream is any of a hybrid stream quantized based on a hybrid optical-electro transfer function (OETF), a High Dynamic Range (HDR) stream quantized based on a non-hybrid OETF, or a Standard Dynamic Range (SDR) stream quantized based on a non-hybrid OETF. Attribute information is received which indicates whether a display apparatus is configured to display at least one of the HDR stream or the SDR stream. Any one of the hybrid stream, the HDR stream, or the SDR stream is transmitted to the display apparatus, or to a reproduction apparatus to which the display apparatus is connected, based on the attribute information.
