Information storage medium including markup document and AV data, recording and reproducing method, and reproducing apparatus therefore

An information storage medium including data readable by an apparatus so as to generate an interactive scene using the data, the data comprising:

• AV data including audio data and video data from which an AV scene is generated, the AV scene having a first screen mode;
• a markup document from which a markup document scene is generated;
• and
• scene synthesis information useable by the apparatus to as to combine the markup document scene with the AV scene to generate the interactive scene without scene distortion of the AV scene due to a change from the first screen mode to a second screen mode.

A method of recording AV data on an information storage medium, the method comprising:

• recording the AV data including audio data and video data to be displayed as an AV scene;
• recording a markup document to be displayed as a markup document scene together with the AV scene;
• and
• recording scene synthesis information which describes and differentiates between display modes which display the markup document scene and the AV scene together as an interactive scene.

A method for reproducing AV data recorded on an information storage medium, the AV data including audio and video data, the method comprising:

• interpreting a markup document to be displayed as a markup document scene together with an AV scene to be displayed from the AV data;
• interpreting scene synthesis information which describes and differentiates between display modes used to display the markup document scene and the AV scene together;
• and
• displaying the AV scene and the markup document scene in a combined scene according to a selected one of the display modes according to the interpreted scene synthesis information.

A method of reproducing AV data, which includes audio data and video data having a predetermined aspect ratio and is recorded on an information storage medium, and a markup document having a predetermined aspect ratio, the method comprising:

• reading scene synthesis information corresponding to a scene mode set by one of a reproducing apparatus and a user;
• interpreting the read scene synthesis information;
• using the read scene synthesis information to display a combined scene including an AV scene, reproduced using the reproduced AV data, and a markup document scene, reproduced using the markup document;
• and
• changing an output state of the markup document scene in response to a scene mode change.

An apparatus which reproduces AV data, which includes audio data and video data, and a markup document which are recorded on an information storage medium, the apparatus comprising:

• a reading unit which reads the AV data and the markup document from the information storage medium;
• a decoder which decodes the AV data read by the reading unit and outputs an AV scene;
• and
• a controller which interprets the markup document read by the reading unit and outputs a markup document scene, interprets scene synthesis information which describes display modes so as to display the markup document scene together the AV scene in a combined scene, and outputs data so as to allow the combined scene to be displayed in one of the display modes according to the interpreted scene synthesis information.

An apparatus which reproduces AV data, which includes audio data and video data, and a markup document which are recorded on an information storage medium, the apparatus comprising:

• a reading unit which reads the AV data and the markup document from the information storage medium;
• a decoder which decodes the AV data read by the reading unit and outputs an AV scene;
• and
• a controller which interprets scene synthesis information corresponding to a scene mode set by the reproducing apparatus or by a received command, interprets the markup document to be displayed as a markup document scene in a combined scene in which the markup document scene is to be displayed together with the AV scene using the interpreted scene synthesis information, outputs data so as to allow the combined scene to be displayed, and changes an output state of the markup document scene in response to a scene mode change.
