Also, a subtitle stream of the high-luminance range is combined with the video stream of the high-luminance range, so a situation will not occur such as an SDR subtitle stream being combined with an HDR video stream.
Thus, according to the above recording medium, playback control such as selecting video streams and so forth is simplified. According to the above-described recording medium, the video stream selection processing and playback processing of a playback device that can play this recording medium can be simplified.
Part of the second playback control information may have a common data structure with the first playback control information.
Accordingly, the playback device can play video streams of the standard-luminance range by about the same processing as video streams of the high-luminance range. This is also advantageous in that authoring by the system is easy, and advantageous in that mounting/operation verification processing of the player is easy (costs can be reduced).
The recording medium may further have recorded therein a management information file including a map region storing map information indicating a position of an independently decodable picture included in a video stream, and an extended map region, wherein the map region stores first map information indicating a position, in a video stream of the high-luminance range, of an independently decodable picture included in a video stream of the high-luminance range, and wherein the extended map region stores second map information indicating a position, in a video stream of the standard-luminance range, of an independently decodable picture included in a video stream of the standard-luminance range.
