Abstract
The present invention relates to an information processing device, an information processing method, a playback device, a playback method, and a recording medium, which enable the same information to be added to pictures corresponding to a basic stream and an extended stream to be used for display of a 3D image. At the time of encoding, Picture Timing SEI to be added to each picture of a Base view video stream, and Picture Timing SEI to be added to each picture of a Dependent view video stream are generated so that a Picture Timing SEI set to be added to the corresponding pictures represents the same content. The present invention can be applied to a playback device compatible with the BD-ROM standard.
