Abstract
The present invention relating to an information processing device, information processing method, playing device, playing method, and program that enables playing of stereo image (3D image) contents appropriately. In the case that 3D playing using Base view video and D1 view video is instructed, “10000.ilvt (ref_to_D1-B_interleaved_file_name) described in interleaved_file_info ( ) of the PlayList file is specified, and Base view video chunks and D1 view video chunks are read out from an optical disc through a UDF file system. The Base view video chunks and D1 view video chunks that are read out are supplied to a decoder unit and played. The present invention is applicable to a playing device compatible with the BD-ROM standard.
Claims17
An information processing device comprising:
- memory;
- and
- circuitry configured to
- set recording state information indicating whether or not a basic stream data and an expanded stream data is recorded on an optical disc in a state of being interleaved in increments of extents which is a predetermined data increment, in a PlayList file that manages the playing of the basic stream and expanded stream generated by encoding multiple pieces of video data with a predetermined encoding method, and
- set, when said basic stream data and said expanded stream data is recorded in the state of being interleaved in said increments of extents, a virtual file that manages the playing of both, said basic stream and said expanded stream in place of said PlayList file, the virtual file replacing said PlayList file.

An information processing method including steps of:
- setting recording state information, indicating whether or not a basic stream data and an expanded stream data is recorded on an optical disc in a state of being interleaved in increments of extents which is a predetermined data increment, in a PlayList file that manages the playing of the basic stream and expanded stream generated by encoding multiple pieces of video data with a predetermined encoding method;
- and
- when said basic stream data and said expanded stream data is recorded in the state of being interleaved in said increments of extents, setting a virtual file that manages the playing of both, said basic stream and said expanded stream in place of said PlayList file, the virtual file replacing said PlayList file.
A non-transitory computer readable medium having stored thereon a program that when executed by a computer causes the computer to execute processing including steps of:
- setting recording state information indicating whether or not a basic stream data and an expanded stream data is recorded on an optical disc in a state of being interleaved in increments of extents which is a predetermined data increment, in a PlayList file that manages the playing of the basic stream and expanded stream generated by encoding multiple pieces of video data with a predetermined encoding method;
- and
- when said basic stream data and said expanded stream data is recorded in the state of being interleaved in said increments of extents, setting a virtual file that manages the playing of both, said basic stream and said expanded stream in place of said PlayList file, the virtual file replacing said PlayList file.
A playing device comprising:
- memory;
- and
- circuitry configured to
- cause a basic stream and an expanded stream to be read out from an optical disc based on a virtual file that manages the playing of both, said basic stream and said expanded stream in place of a PlayList file, the virtual file replacing said PlayList file in the case that recording state information in the PlayList file indicates that the data is recorded in an interleaved state in said extent increments, the recording state information indicating whether or not said basic stream data and said expanded stream data is recorded on an optical disc in the state of being interleaved in increments of extents which is a predetermined data increment, which is set in the PlayList file that manages the playing of the basic stream and expanded stream generated by encoding multiple pieces of video data with a predetermined encoding method.
