Information processing apparatus, information processing method, recording medium, playback apparatus, playback method, and program

An information processing method, wherein

• an information processing apparatus
• generates dynamic metadata including information regarding luminance of a picture, and
• encodes HDR video data such that the dynamic metadata is added to each picture serving as a random access point.

A program configured to cause a computer to execute processes of:

• generating dynamic metadata including information regarding luminance of a picture;
• and
• encoding HDR video data such that the dynamic metadata is added to each picture serving as a random access point.

A recording medium, wherein

• a video stream generated by encoding HDR video data such that dynamic metadata including luminance information is added to each picture serving as a random access point is recorded.

A playback apparatus comprising:

• a playback unit that performs random access playback of a video stream generated by encoding HDR video data such that dynamic metadata including luminance information is added to each picture serving as a random access point;
• and
• an output control unit that outputs the picture serving as the random access point to a display apparatus along with the dynamic metadata.

A playback apparatus comprising:

• a playback unit that performs random access playback of a video stream to which dynamic metadata including information regarding luminance of a picture is added;
• and
• an output control unit that, in a case where predetermined information indicating that random access playback is being performed is to be superimposed on the picture and displayed, adds metadata to be used during random access playback for luminance adjustment during the random access playback to the picture serving as a random access point, and outputs the picture to which the metadata to be used during the random access playback is added to a display apparatus.
