摘要： A display system includes a conversion apparatus converting video luminance including a luminance value in a first luminance range and a display apparatus connected thereto and displaying the video. The conversion apparatus includes a first acquisition unit, a first luminance converter, a second luminance converter, a quantization converter, and an output unit outputting a third luminance signal to the display apparatus. The display apparatus includes: a second acquisition unit acquiring the third luminance signal and setting information indicating display settings recommended to the display apparatus in display of the video; a display setting unit setting the display apparatus, using the setting information; a third luminance converter converting a third code value indicated by the third luminance signal into a second luminance value compatible with a second luminance range, using the setting information; and a display controller displaying the video on the display apparatus based on the second luminance value.

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： An AV signal transmission and receiving system capable of appropriately receiving an AV signal includes a source apparatus and a sink apparatus connected to the source apparatus via an HDMI (registered trademark) cable. The sink apparatus includes: an AV signal receiving unit which receives an AV signal via the HDMI cable; a memory which holds the EDID; a rewriting unit which rewrites the EDID; an HPD control unit which controls output of an HPD signal; and a determining unit which: determines whether the AV signal which has been received is an HDMI signal conforming to an HDMI standard or a digital visual interface (DVI) signal; and when the determining unit determines that the AV signal is a DVI signal, instructs the rewriting unit to rewrite the EDID and instructs the HPD control unit to output the HPD signal indicating that reading of the EDID which has been rewritten is possible.

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.
