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.
Claims14
A playback device that reads out and plays contents from a non-transitory computer-readable medium,
- wherein, recorded in the non-transitory computer-readable medium are
- 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 playback device includes
- a video playback unit that reads out and plays the base video stream and the enhanced video stream based on the management information file,
- wherein the base video 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.
A playback method of reading out and playing contents from a non-transitory computer-readable medium,
- wherein, recorded in the non-transitory computer-readable medium are
- 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,
- and the playback method comprising:
- reading out and playing the base video stream and the enhanced video stream based on the management information file,
- wherein the base video is 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.
