Reproduction device, reproduction method, and program

A reproduction device comprising:

• a readout unit configured to read out, from a recording medium recording a content, a file of a video stream and a file of reproduction management information used for reproducing the video stream and including monitor information indicating a color gamut and a dynamic range of luminance of a master monitor used for authoring the video stream;
• a decoding unit configured to decode the video stream;
• and
• an output unit configured to control an output of video data obtained by decoding the video stream and the monitor information included in the reproduction management information to a display device, depending on a performance of the display device to which the content is output such that where a dynamic range of luminance indicated by the monitor information is wider than a dynamic range of luminance of a display unit included in the display device the output of video data is output with a reduced dynamic range of luminance,
• wherein the reproduction management information includes a flag indicating whether or not the monitor information is included in the video stream, and
• wherein the reproduction device further comprises:
• an acquisition unit configured to acquire the monitor information from the video stream in a case where the flag indicates that the monitor information is included in the video stream;
• and
• a control unit configured to perform processing on the basis of the monitor information acquired by the acquisition unit, of the monitor information acquired by the acquisition unit and the monitor information included in the reproduction management information.

A reproduction method comprising the steps of:

• reading out, by a drive, from a recording medium recording a content, a file of a video stream and a file of reproduction management information used for reproducing the video stream and including monitor information indicating a color gamut and a dynamic range of luminance of a master monitor used for authoring the video stream;
• decoding the video stream by a decoder;
• and
• controlling an output of video data obtained by decoding the video stream and the monitor information included in the reproduction management information to a display device, depending on a performance of the display device to which the content is output such that where a dynamic range of luminance indicated by the monitor information is wider than a dynamic range of luminance of a display unit included in the display device the output of video data is output with a reduced dynamic range of luminance.

A non-transitory storage medium configured to store a program for causing a computer to execute processing comprising the steps of:

• reading out, by a drive, from a recording medium recording a content, a file of a video stream and a file of reproduction management information used for reproducing the video stream and including monitor information indicating a color gamut and a dynamic range of luminance of a master monitor used for authoring the video stream;
• decoding the video stream by a decoder;
• and
• controlling an output of video data obtained by decoding the video stream and the monitor information included in the reproduction management information to a display device, depending on a performance of the display device to which the content is output such that where a dynamic range of luminance indicated by the monitor information is wider than a dynamic range of luminance of a display unit included in the display device the output of video data is output with a reduced dynamic range of luminance.
