Abstract: A playback method of reading out and playing streams from a recording medium is provided, in which are recorded a stream file including a first luminance video expressed by luminance of a first dynamic range, and a second luminance video expressed by luminance of a second dynamic range that is broader than the first dynamic range, and a playlist file for controlling playback of the stream file. The playback method includes, in a case of playing the first luminance video, reading out the first audio streams listed in the first combination information of the playlist file, and playing at the same time with the first luminance video, and in a case of playing the second luminance video, reading out the second audio streams listed in the second combination information of the playlist file, and playing at the same time with the second luminance video.

Abstract: A playback method is provided for reading out and playing streams from a recording medium. Recorded in the recording medium are a stream file including a first luminance video expressed by luminance of a first dynamic range, and a second luminance video expressed by luminance of a second dynamic range that is broader than the first dynamic range; a playlist file for controlling playback of the stream file; and a number of elementary streams. The playback method includes when playing the first luminance video, reading out any one of the elementary streams listed in the first combination information of the playlist file, and playing at the same time with the first luminance video; and when playing the second luminance video, reading out any one of the elementary streams listed in the second combination information of the playlist file, and playing at the same time with the second luminance video.

Abstract: A playback method of reading out and playing streams from a recording medium is provided. A stream file. including a first luminance video and a second luminance video, a playlist file, first and second combination information, elementary streams that can be played together with the first luminance video, and elementary streams that can be played together with the second luminance video are recorded in the recording medium. The playback method includes, when playing the first luminance video, reading out any one of the elementary streams listed in the first combination information of the playlist file, and playing at the same time with the first luminance video, and when playing the second luminance video, reading out any one of the elementary streams listed in the second combination information of the playlist file, and playing at the same time with the second luminance video.

Abstract: A recording medium is provided in which are recorded a stream file, including a first luminance video expressed by luminance of a first dynamic range, and a second luminance video expressed by luminance of a second dynamic range that is broader than the first dynamic range, and a playlist file for controlling playback of the stream file. The recording medium includes first and second combination information, representing combinations of first and second audio streams that each can be played at the same time in a same playback section with the first luminance video and the second luminance video, being described in the playlist file. The recording medium also includes the first audio streams that can be played at the same time with the first luminance video in this playback section being all listed in the first combination information.
