Abstract: A disc in which a digital versatile disc (DVD) application is recorded in a physical layer of the disc, a recording/reproducing apparatus, and a recording/reproducing method are provided. In the disc, a lead-in area, a lead-out area and a user area, each having a compact disc read only memory (CD-ROM) format, are distinguished on the physical layer of the disc and a digital versatile disc (DVD) application, according to a predetermined file system, is recorded in the user area. Therefore, a low-priced disc can be used for a music video or a presentation which requires only a shorttime to reproduce since the DVD application can be recorded on and reproduced from the disc to obtain multiple functions having high image quality and high sound quality.

Abstract: An audio recording medium, methods for recording data on and reproducing data from the audio recording medium, and recording and reproducing apparatuses therefor. In the audio recording medium, audio data are recorded in a plurality of tracks in predetermined write units, and identification data for indicating the start position of each of the tracks, such as mute data, are recorded in write units segregated from the predetermined write units of the audio data. Thus, if a mute period is unnecessary, the mute data can be easily removed.

Abstract: A method for reproducing AV data in an interactive mode using a markup document includes dividing an operation state of a presentation engine for reproducing the markup document into a start state, a reproduction state, a pause state, and a stop state. In the reproduction state, the presentation engine performs a preloading process for reading the markup document into a memory, a loading process for interpreting the markup document and loading the markup document on a display screen, and an interacting process for facilitating an interaction between the markup document and a user.

Abstract: A storage medium which stores catalog information and a catalog information recording and/or playback apparatus and method therefor. Using the method, catalog information including a still picture and additional information together with audio data are recorded on a storage medium such as a digital versatile disk (DVD), which is an optical record storage medium, and the catalog information is played back during playback of the audio data, to thereby provide various information on the audio data. Also, the apparatus includes a buffer memory for catalog playback which maintains a predetermined standard and compatibility, and is capable of real-time reading during playback of the audio data, and automatically plays back the catalog content, corresponding to the playback state of the audio data, when there is no additional selection of a user.

Abstract: A method and apparatus for mixing audio streams, and an information storage medium that stores mixing information. The information storage medium includes at least one audio stream that contains a multiplicity of audio data obtained from respective multiple channels, and mixing information used to mix at least parts of the multiplicity of audio data. Accordingly, it is possible to mix and reproduce different types of channel components without changing the channel formats of different audio streams. Furthermore, it is also possible to perform dynamic mixing on multiple channel components, thus enabling adaptation to a change in audio content and characteristics thereof and thereby reproducing audio data more appropriately. In particular, since mixing information is described in interactive data allowing an interaction with a user, it is possible to provide the user with more applications.

Abstract: An information storage medium storing at least one still image data clip including: at least one still image data file; still image clip information including information on a position and attributes of still images in the at least one still image data file; and still image sequence information including information on presentation modes and a presentation time for the still images in the at least one still image data file.

Abstract: An information storage medium which stores data structures supporting multi-angles includes clip AV streams for respective angle data of multi-angle motion picture data. As additional information for each clip AV stream, clip information is recorded on a separate storage area from that of the clip AV streams. The clip information includes jumping-point information for jumping into another angle. Each of the clip AV streams may be recorded in a contiguous recording area, or divided into smaller interleaved units that are interleaved with units of the other clip AV streams.

Abstract: An information storage medium on which multi-angle data is recorded includes at least two clips in each of which video object data for an angle of the multi-angle data is recorded. The at least two clips are recorded in contiguous areas of the information storage medium.

Abstract: A DVD-Audio which includes a data zone for storing data to be reproduced and an information zone for storing information on the data to be reproduced. The information zone includes directories of a video title set (VIDEO_TS) and an audio title set (AUDIO_TS). The AUDIO_TS directory includes information on an audio manager (AMG) having information on audio titles. The data zone includes the audio titles each having an audio title set information (ATSI) followed by a plurality of contiguous audio objects (AOBs). The ATSI includes a plurality of audio stream attributes each having an audio coding mode, first to third quantization bit numbers, first to third sampling frequencies and decoding algorithm information relating to the number of audio channels. Each of the AOBs includes a plurality of audio packs recorded with audio data corresponding to the decoding algorithm stored in the audio stream attribute.

Abstract: An apparatus and a method of executing an applet in an apparatus reproducing interactive contents. The method involves receiving a request for executing an applet from a browser, determining whether the applet is a bound applet or an unbound applet, and loading the applet into a virtual machine. If the loaded applet is an unbound applet, predetermined commands to the virtual machine are issued, so that the applet can fall into an ‘initiate’ state and into a ‘start’ state, respectively.

Abstract: A method and an apparatus displaying a markup document linked to an applet by delaying display of image output information for the markup document and synchronously displaying the delayed image output information for the markup document and an applet output when rendering of the applet is completed. The markup document linked to an applet is displayed by synchronizing the applet and the markup document outputs so that an initial blank applet image is not displayed while initializing and executing the applet. Accordingly, a user conveniently views a markup image linked to an applet.
