Information storage medium including markup document and av data, recording and reproducing method, and reproducing apparatus therefore description/claims

This application is a continuation of application Ser. No. 10/278,092, filed Oct. 23, 2002, currently pending, which claims the benefit of Korean Patent Application Nos. 2001-65388, 2002-14586, and 2002-30609, filed Oct. 23, 2001, Mar. 18, 2002, and May 31, 2002, respectively in the Korean Intellectual Property Office, the disclosures of which are incorporated herein in their entirety by reference.

1. Field of the Invention

The present invention relates to a method of displaying audio/video (AV) data together with a markup document, and more particularly, to an information storage medium including a markup document and AV data so that the markup document and the AV data can be reproduced and displayed together in various ways in an interactive mode, a recording and a reproducing method, and a reproducing apparatus therefore.

2. Description of the Related Art

Digital video discs (DVDs) (hereinafter, referred to as “interactive DVDs”) on which a markup document is recorded together with audio/video (hereinafter, referred to as AV data), have been initially developed for movie applications. However, the interactive DVDs have started to be widely used in the computer industry. The AV data recorded on the interactive DVDs can be reproduced in two ways: a video mode which is displayed identically as compared to a conventional DVD, and an interactive mode in which reproduced the AV data is displayed in a display window defined by a markup document. If the interactive mode is selected by a user, a viewer installed in a DVD reproducing apparatus displays the markup document recorded on an interactive DVD. The AV data selected by the user is displayed in the display window of the markup document. For example, when the AV data is a movie, the movie is run in the display window of the markup document, and various additional information including scenario, history, and actors' pictures related to the movie are displayed in the remaining part of a screen excluding the display window of the markup document. The additional information includes image files or text files.

However, until now, in the interactive mode, the AV data is based on a simple displaying method in which the AV data is displayed through the display window defined according to grammar of markup languages.

To solve the above and other problems, it is an object of the present invention to provide an information storage medium including AV data and a markup document so that the AV data and the markup document can be reproduced and displayed in various ways in an interactive mode, a recording method, a reproducing method, and a reproducing apparatus therefore.

It is another object of the present invention to provide an information storage medium including the AV data and a markup document so that the AV data and the markup document can be displayed in various ways in an interactive mode according to a resolution and an aspect ratio (screen ratio), which are set by a user or set in a reproducing apparatus, a recording method, a reproducing method, and a reproducing apparatus therefore.

It is still another object of the present invention to provide an information storage medium including interactive contents manufactured at a fixed aspect ratio so that the interactive contents can be effectively displayed on a display having various aspect ratios, a recording method, a reproducing method, and a reproducing apparatus therefore.

Additional objects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Accordingly, to achieve the above and other objects according to an embodiment of the present invention, there is provided an information storage medium includes AV data including audio data and video data, a markup document, and scene synthesis information which describes one of at least two display modes for displaying a markup document scene obtained from the markup document and an AV scene obtained from the AV data together.

According to an aspect of the invention, the scene synthesis information includes a link tag recorded in the markup document, and the scene synthesis information includes a cascading style sheet (CSS) inserted in the link tag.

According to another aspect of the invention, the CSS includes at least one of display mode designation information for designating a display mode of the AV scene, AV trimming area designation information for designating an area to increase and reduce a desired portion of the AV scene, background color designation information for designating a background color of the AV scene, trimming area designation information for designating a trimming area of a scene in which the AV scene is synthesized with the markup document, window designation information for designating a window in which a scene where the AV scene is synthesized with the markup document is displayed on the screen of a display, screen display type information representing an aspect ratio of a scene in which the AV scene is synthesized with the markup document scene, and window designation information of the AV scene for designating an area of a window in which a trimmed AV scene is displayed on the screen of the display.

According to a further aspect of the invention, the scene synthesis information further includes an object having property variables for controlling the CSS and a program for controlling the CSS on the basis of the object.

According to another embodiment of the present invention, a method for recording AV data, including audio data and video data on an information storage medium, comprises recording the AV data, recording a markup document to be displayed together with the AV data, and recording scene synthesis information which describes one of at least two display modes for displaying a markup document scene obtained from the markup document and an AV scene obtained from the AV data together.

According to an aspect of the invention, the AV data is recorded in a video directory, the markup document is recorded in an interactive directory, and the scene synthesis information is recorded in the interactive directory.

According to another aspect of the invention, contents which are to be displayed are recorded in a maximum area shown regardless of an aspect ratio of the display (i.e., in a hot area), and unimportant contents are recorded or any contents are not recorded in the other area, wherein, when the markup document having a first aspect ratio is displayed on a display having a second aspect ratio having a resolution lower than that of the first aspect ratio, the hot area is selected using the trimming area designation information of the synthesized scene, and the selected hot area is mapped to a designated area on the screen of the display using the window designation information of the synthesized scene.

According to still another embodiment of the present invention, a method for reproducing AV data, including audio data and video data recorded on an information storage medium comprises interpreting a markup document to be displayed together with the A data, interpreting scene synthesis information which describes at least two display modes for displaying a markup document scene obtained by reproducing the markup document and an AV scene obtained by reproducing the AV data together, and displaying the AV scene and the markup document scene in one of the display modes according to the interpreted scene synthesis information.
