Title: PLAYBACK DEVICE, PLAYBACK METHOD, AND RECORDING MEDIUM
Abstract:
This technology pertains to a playback device, playback method, and recording medium whereby graphics having a high luminance dynamic range can be displayed at an appropriate brightness. A Tone_map stream and a graphics stream representing HDR graphics having a second luminance range that differs from and is higher than a first luminance range are recorded on an optical disc. The Tone_map stream contains the following: tone_mapping_info containing HDR information indicating the luminance characteristics of the HDR graphics; and tone_mapping_info consisting of tone-mapping definition information used when performing a luminance conversion from the HDR graphics to STD graphics having the aforementioned first luminance range. This technology can be applied to a recording medium on which graphics are recorded.
