Abstract: A playback device reads out from a recording medium and plays multiple High Dynamic Range (HDR) video streams that are encoded with video information. The playback device includes a first register, a second register and a playback unit. For each of the HDR video streams, the first register stores first information indicating whether the playback device corresponds to or not, and the second register stores second information indicating whether a display device connected to the playback device corresponds to or not. The playback unit plays the HDR video streams using a playback format selected based on a playback program stored in the recording medium, in a case where the first information and the second information indicate that there are multiple playback formats corresponding to both the playback device and the display device.

Abstract: A recording medium includes a video stream of a standard-luminance range and a video stream of high-luminance range, which are used selectively in accordance with a playback environment. The recording medium also includes a subtitle stream of the standard-luminance range and a subtitle stream of the high-luminance range, which are used selectively in accordance with the playback environment. A playlist file includes a management region where playback control information relating to a main stream is stored, and includes an extended region. The management region stores first playback control information specifying playing of the video stream of the high-luminance range and the subtitle stream of the high-luminance range in combination. The extended region stores second playback control information specifying playing of the video stream of the standard-luminance range and the subtitle stream of the standard-luminance range in combination.

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.

Abstract: A recording medium is provided in which are recorded a video stream that is encoded video information, map information, and bitrate information of the video stream. The map information includes playback start time information of a picture that is independently decodable, start position information indicating a data start position of the picture, and size information indicating a data size of a section where the picture is recorded, based on a predetermined stipulated data size, which differs in accordance with the bitrate information. The size information indicates a data size based on a first stipulated data size, where the bitrate information indicates a bitrate larger than a predetermined value, and indicates a data size based on a second stipulated data size that is smaller than the first stipulated data size, where the bitrate information indicates a bitrate equal to or smaller than the predetermined value.
