Authoring method, authoring device and program

An authoring method comprising:

• generating a second real image having a stream data structure of a second file system different from a first file system including time-division multiplexed material data;
• generating a third materialization file that does not include material data, and referencing recording positions of third material data associated with the third materialization file and the second real image to mount a first real image having a stream data structure of the first file system that includes time-division multiplexed material data;
• generating a virtual clip file arranged under a structure of directories;
• and arranging the third materialization file under the virtual clip file as a directory associated with a first virtual image to generate a second virtual image;
• wherein the virtual clip is generated without copying real material data, and the virtual clip includes an elementary stream (ES) reference table having:
• a packet base file, a packet information file, a seek list file, and an ES list file.

An authoring device comprising;

• a first materialization file generator that generates a first materialization file that does not include material data, and referencing a recording position of first material data associated with the first materialization file to mount a first real image having a stream data structure of a first file system, the first file system including time-division multiplexed material data;
• a second materialization file generator that generates a second materialization file that does not include material data, and referencing a recording position of second material data associated with the second materialization file to mount a second real image having a stream data structure of a second file system, the second file system being different from the first file system that includes time-division multiplexed material data;
• a virtual clip file generator that generates a virtual clip file arranged under a structure of directories;
• and a first virtual image generator that arranges the first materialization file and the second materialization file under the virtual clip file as a directory of a first virtual image to generate the first virtual image;
• wherein the virtual clip is generated without copying real material data, and the virtual clip includes an elementary stream (ES) reference table having:
• a packet base file, a packet information file, a seek list file, and an ES list file.

An authoring device comprising:

• a generator that generates a virtual clip file arranged under a structure of directories;
• and a second virtual image generator that arranges the third materialization file under the virtual clip file as a directory associated with a first virtual image to generate a second virtual image;
• wherein the virtual clip is generated without copying real material data, and the virtual clip includes an elementary stream (ES) reference table having:
• a packet base file, a packet information file, a seek list file, and an ES list file.

A non-transitory computer-readable storage medium storing computer-readable instructions that, when executed by a computer, cause the computer to perform a method comprising:

• generating a first materialization file that does not include material data, and referencing a recording position of first material data associated with the first materialization file to mount a first real image having a stream data structure of a first file system, the first file system including time-division multiplexed material data;
• generating a second materialization file that does not include material data, and referencing a recording position of second material data associated with the second materialization file to mount a second real image having a stream data structure of a second file system, the second file system being different from the first file system that includes time-division multiplexed material data;
• generating a virtual clip file arranged under a structure of directories;
• and arranging the first materialization file and the second materialization file under the virtual clip file as a directory associated with a first virtual image to generate the first virtual image;
• wherein the virtual clip is generated without copying real material data, and the virtual clip includes an elementary stream (ES) reference table having:
• a packet base file, a packet information file, a seek list file, and an ES list file.
