`
`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 recommendedto the display apparatus in
`
`display of the video; a display setting unit setting the display apparatus, using the setting
`
`10
`
`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 luminancevalue.
