摘要： 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.

摘要： The object of the present invention is to provide a reproduction apparatus that is capable of preventing personal information of users from being transmitted to an external apparatus that is under management of a malicious person. The reproduction apparatus uses a revocation list and a valid-content list in combination in order to prevent transmission of personal information of users. It is possible to prevent transmission of personal information by revoking certificates to be revoked because of being exposed or hacked at a certain timing, by listing them in the revocation list. Meanwhile, it is possible to allow use of contents that have been manufactured before the exposure, by listing them in the valid-content list. Accordingly, it is possible to realize both the security and the user convenience at the same time.

摘要： 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.

摘要： In a reproduction method that reproduces a video stream, the video stream has a first dynamic range where a maximum value of a luminance dynamic range is more than 100 nits, a display apparatus displays video in a second dynamic range narrower than the first dynamic range, and it is determined whether the video stream is quantized based on a hybrid OETF. When it is determined that the video stream is quantized based on the hybrid OETF, the video stream is reproduced without performing luminance conversion on the video stream, the luminance conversion converting from the first dynamic range to the second dynamic range. When it is determined that the video stream is not quantized based on the hybrid OETF, the luminance conversion is performed on the video stream and the video stream is reproduced.
