PLAYBACK DEVICE, PLAYBACK METHOD, AND RECORDING MEDIUM |
摘要 |
A playback device includes: an attribute reader 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 decoder that generates decoded video information by reading the video stream out from the recording medium and decoding the video stream; and an outputter 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. |

1. A playback device that reads out a video stream, which is encoded video information, from a recording medium, and plays the video stream, the playback device comprising:
an attribute reader 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 that is wider than the first dynamic range, from a management information file recorded in the recording medium in a manner correlated with the video stream; a decoder that generates decoded video information by reading the video stream out from the recording medium and decoding the video stream; and an outputter 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. |
