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

An information processing method comprising:

• generating dynamic metadata including information regarding luminance of a picture;
• and
• encoding high dynamic range (HDR) video data such that the dynamic metadata is added to each picture serving as a random access point,
• wherein, in a case where predetermined information indicating that random access playback is being performed is to be superimposed on the picture and displayed, the dynamic metadata is used for adding 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.

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

• generating dynamic metadata including information regarding luminance of a picture;
• and
• encoding high dynamic range (HDR) video data such that the dynamic metadata is added to each picture serving as a random access point,
• wherein, in a case where predetermined information indicating that random access playback is being performed is to be superimposed on the picture and displayed, the dynamic metadata is used for adding 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.

A playback apparatus comprising:

• a playback unit configured to perform random access playback of a video stream generated by encoding high dynamic range (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 configured to output the picture serving as the random access point to a display apparatus along with the dynamic metadata,
• wherein, in a case where predetermined information indicating that random access playback is being performed is to be superimposed on the picture and displayed, the dynamic metadata is used for adding 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
• wherein the playback unit and the output control unit are each implemented via at least one processor.

A playback method comprising:

• performing random access playback of a video stream to which dynamic metadata including information regarding luminance of a picture is added;
• in a case where predetermined information indicating that random access playback is being performed is to be superimposed on the picture and displayed, adding 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
• outputting the picture to which the metadata to be used during the random access playback is added to a display apparatus.
