• determining whether multimedia elements other than text files exist in a markup document to be reproduced together with the AV data read from the information storage medium;
• and
• upon determining that multimedia elements exist in the markup document, checking a current version of the multimedia elements in the markup document and a minimum viewer version to reproduce the multimedia elements, and reproducing the multimedia elements according to the result of checking.

A recording apparatus comprising:

• a recording unit recording audio and/or video (AV) data on an information storage medium, and recording a markup document defining a display window in which the AV data is displayed, and recording specification version information of the markup document and minimum interactive contents version information to be reproduced by a reproducing apparatus in the markup document, on the information storage medium.

A recording apparatus comprising:

• a recording unit recording audio and/or video (AV) data, recording a markup document defining a display window in which the AV data is displayed on an information storage medium, and recording minimum markup version information and/or minimum multimedia version information to be reproduced by a reproducing apparatus.

A reproducing apparatus reproducing AV data recorded on an information storage medium in an interactive presentation mode, comprising:

• a reader reading specification version information of a markup document to be reproduced together with the AV data and minimum interactive contents version information to be reproduced from the information storage medium;
• and
• a controller interpreting and displaying the markup document according to the minimum interactive contents version information when the specification version information of the markup document is higher than version information of the reproducing apparatus reading the information storage medium.

A reproducing apparatus reproducing AV data recorded on an information storage medium in an interactive presentation mode, comprising:

• a reader reading a markup document having multimedia elements from the information storage medium;
• and
• a controller determining whether multimedia elements other than text files exist in a markup document to be reproduced together with the AV data read from the information storage medium, and upon determining that multimedia elements exist in the markup document, checking a current version of the multimedia elements in the markup document and a minimum viewer version to reproduce the multimedia elements, and reproducing the multimedia elements according to the result of the checking.

A recording and reproducing apparatus comprising:

• a recording unit recording audio and/or video (AV) data on an information storage medium, and recording a markup document defining a display window in which the AV data is displayed, and recording specification version information of the markup document and minimum interactive contents version information to be reproduced from the markup document, on the information storage medium;
• and
• a reproducing unit reading the specification version information of the markup document to be reproduced together with the AV data and the minimum interactive contents version information to be reproduced from the information storage medium, and interpreting and displaying the markup document according to the minimum interactive contents version information when the specification version information of the markup document is higher than version information of the reproducing apparatus reading the information storage medium.

A recording and/or reproducing apparatus comprising:

• a recording unit recording audio and/or video (AV) data, and recording a markup document defining a display window in which the AV data is displayed on an information storage medium, and recording minimum markup version information and/or minimum multimedia version information to be reproduced by the reproducing apparatus;
• and
• a reproducing unit reading multimedia elements of a markup document, determining whether the multimedia elements other than text files exist in the markup document to be reproduced together with the AV data read from the information storage medium, checking a current version of the multimedia elements in the markup document and minimum viewer version that can reproduce the multimedia elements, from the minimum markup version information and/or minimum multimedia version information upon determining that the multimedia elements exist in the markup document, and reproducing the multimedia elements according to a result of the checking the current version of the multimedia elements.

A reproducing apparatus reading data including AV data and a markup document from an information storage medium and generating an AV scene and a markup document scene using the AV data and the markup document in an interactive presentation mode, comprising:

• a reader reading specification version information and minimum interactive contents version information from the information storage medium in the interactive presentation mode;
• and
• a controller having a presentation engine having a viewer version to interpret the markup document, and the controller generating a message representing that the presentation engine does not support reproducing of the markup document from the information storage medium, according to the viewer version, a minimum interactive contents version obtained from the minimum interactive contents version information, and a specification version obtained from the specification version information.

A reproducing apparatus reading data from an information storage medium having an AV directory and an interactive presentation directory containing a markup document to generate an AV scene and a markup document scene in an interactive presentation mode, comprising:

• a reader reading a markup document including reproduction control information having minimum interactive contents version information from the interactive presentation directory of the information storage medium in the interactive presentation mode;
• and
• a controller having a presentation engine having a user agent version, obtaining a minimum interactive contents version according to the minimum interactive contents version information and a specification version from the reproduction control information, and interpreting the markup document in the minimum interactive contents version instead of the specification version.
