Abstract: A recording medium is a disc-shaped recording medium having a plurality of recording layers, in which a video stream is recorded on the plurality of recording layers. Part of the video stream is recorded up to a first recording position on a first recording layer of the plurality of recording layers. A remaining part of the video stream is recorded from a second recording position of a second recording layer adjacent to the first recording layer. The video stream is seamlessly connected between the first recording position and the second recording position, and a first distance between the first recording position and the second recording position in the radial direction of the recording medium is smaller than a second distance in the radial direction regarding which a jump is permitted in seamless connection within a same recording layer.

Abstract: A playback device includes: an attribute readout unit that reads out first attribute information, indicating whether a dynamic range of luminance of the video stream is a first dynamic range or a second dynamic range, from a management information file recorded in the recording medium in a manner correlated with the video stream; a decoding unit that generates decoded video information by reading the video stream out from the recording medium and decoding the video stream; and an output unit that, in a case where the first attribute information that has been read out indicates the second dynamic range, outputs the decoded video information, along with maximum luminance information indicating a maximum luminance of the video stream in accordance with the second dynamic range.
