Reproduction apparatus, reproduction method, program, and recording medium

A reproduction method performed by a reproduction apparatus, comprising:

• decoding, in a case where a first content including a first HDR video stream to which dynamic metadata including respective luminance information of each respective video frame is added and a second content including a second HDR video stream to which the dynamic metadata is not added and with which static metadata including average luminance information of a unit of overall content is associated are included in reproducible contents and the second content is to be reproduced, the second HDR video stream;
• adding the dynamic metadata of the first HDR video stream to each respective video frame of video data obtained by the decoding of the second HDR video stream;
• and
• outputting resulting data to a display apparatus.

A non-transitory computer-readable storage medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:

• decoding, in a case where a first content including a first HDR video stream to which dynamic metadata including respective luminance information of each respective video frame is added and a second content including a second HDR video stream to which the dynamic metadata is not added and with which static metadata including average luminance information of a unit of overall content is associated are included in reproducible contents and the second content is to be reproduced, the second HDR video stream;
• adding the dynamic metadata of the first HDR video stream to each respective video frame of video data obtained by the decoding of the second HDR video stream;
• and
• outputting resulting data to a display apparatus.

A non-transitory recording medium having recorded therein:

• a first HDR video stream to which dynamic metadata including respective luminance information of each respective video frame is added;
• a second HDR video stream to which the dynamic metadata is not added and with which static metadata including average luminance information of a unit of overall content is associated;
• a playlist file having the static metadata described therein, the playlist file including reproduction re-controlling information of the second HDR video stream;
• and
• an index file in which a flag representative of a type of an HDR video stream is described, the index file including a bit indicative of whether or not the first HDR video stream is recorded and a bit indicative of whether or not the second HDR video stream is recorded,
• wherein when the index file includes the bit indicative of the first HDR video stream being recorded and the bit indicative of the second HDR video stream being recorded, the playlist file includes the reproduction re-controlling information of the second HDR video stream by adding the dynamic metadata of the first HDR video stream.
