Abstract:
A non-transitory recording medium is provided that is reproduced by a playback device having an attribute reader, a decoder, and an outputter. The recording medium has recorded therein a video stream that is encoded video information, and a management information file correlated with the video stream. The management information file includes first attribute information, indicating whether a dynamic range of luminance of the video stream is a first dynamic range or a second dynamic range that is wider than the first dynamic range. In a case where the first attribute information indicates the second dynamic range, the first attribute information also indicates a type of the second dynamic range.
