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 playback device plays video streams recorded in a recording medium, in which are one or more video streams including at least one of an HDR stream whose dynamic range of luminance of video corresponds to a high dynamic range (HDR), and an SDR stream whose dynamic range of luminance of video corresponds to a standard dynamic range (SDR) narrower than HDR, and identification information indicating whether the HDR stream is included in the one or more video streams. A playback method of the playback device includes: reading the identification information from the recording medium; acquiring playback capability information indicating whether the playback device can play the HDR stream, and display capability information indicating whether a connected display device can display the HDR video; and deciding on a video stream from the one or more video streams, according to the identification information, the playback capability information, and the display capability information.

Abstract: A playback method of reading out and playing streams from a recording medium is provided in which are recorded a stream file, a playlist file, first and second combination information, elementary streams that can be played at the same time with the first luminance video, and elementary streams that can be played at the same time with the second luminance video. The playback method includes in a case of 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 in a case of 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 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 recording medium is provided in which are recorded a stream file including a first luminance video expressed by luminance of a first dynamic range, 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 first and second combination information, representing combinations of elementary streams that can be played at the same time, is described in the playlist file. Elementary streams that can be played at the same time with the first luminance video are listed in the first combination information. Elementary streams that can be played at the same time with the second luminance video are listed in the second combination information. The number of elementary streams of a predetermined type listed in the first combination information and the second combination information are equal.

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.
