Abstract
At least one video stream that is encoded video information, and a management information file indicating attributes relating to the entire recording medium, are recorded in a recording medium. The management information file includes attribute information indicating whether the dynamic range of luminance of an initial video stream, which is played first out of the at least one video stream when the recording medium is inserted into a playback device, is a first dynamic range, or a second dynamic range that is broader than the first dynamic range.
Claims7
A non-transitory computer-readable medium, in which are recorded
- a base video stream that is encoded video information,
- an enhanced video stream that is encoded video information, for enhancing luminance of the base video stream by being played synchronously with the base video stream, and
- a management information file in which is described a playback path of the base video stream,
- wherein a playback path of the enhanced video stream is further described in the management information file so that the enhanced video stream is played synchronously with the base video stream,
- wherein the base video stream includes High Dynamic Range (HDR), and
- wherein the enhanced video stream, by being played synchronously with the base video stream, realizes a higher luminance than the base video stream.
