Abstract

A method to be performed by a playback device includes determining whether the playback device has a function for converting first graphics in a second luminance range narrower than a first luminance range to second graphics in the first luminance range, when the playback device has the function, converting the first graphics to the second graphics, and displaying a video in the first luminance range with the second graphics being superimposed on the video, and when the playback device does not have the function, displaying the video with third graphics different from the second graphics being superimposed on the video.

Claims7

Dependent claims

A playback device comprising:

a first remapper that reads a video signal having a first luminance range from a recording medium, performs electro-optical transfer function (EOTF) conversion associated with the first luminance range on a code value represented by a luminance signal in the video signal to obtain a first luminance value, and converts the first luminance value into a second luminance value associated with a second luminance range different in maximum value from the first luminance range;
a second remapper that reads a graphics signal having the first luminance range from the recording medium and performs the EOTF conversion associated with the first luminance range on a code value represented by a luminance signal in the graphics signal to obtain a first luminance value;
a synthesizer that synthesizes the video signal having a luminance value converted by the first remapper with the graphics signal having a luminance value not converted by the second remapper;
and
an outputter that outputs a signal synthesized by the synthesizer to a display device.
