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: 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.

Abstract: In a converting method relating to picture luminance according to one aspect of the present disclosure, the picture luminance is formed by luminance values in a first luminance range. In this method, a first luminance signal that indicates code values obtained by quantizing the luminance value of the picture is obtained, code values, which are associated with the code values indicated by the obtained first luminance signal by quantization for a second luminance range different in a maximum value from the first luminance range are determined as converted code values, and the first luminance signal is converted into a second luminance signal indicating the converted code values. As a result, the converting method is further improved.
