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.

Apparatus for recording and/or playing back catalog information

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.

Information storage medium having multi-angle data structure and apparatus therefor

An optical recording medium having a read-only storage area and a writable storage area and a recording/reproducing apparatus and method therefor. The optical recording medium is a hybrid disc having both the read-only storage area, which is suitable for mass production of information having the same contents, and the writable storage area on which data can be recorded, updated or added at a user's option. The read-only storage area has a structure that is completely compatible with a digital versatile disc read only memory (DVD-ROM) specification, and the writable storage area is compatible with the recording/reproducing characteristics of a writable DVD specification so that an existing reproducing-only apparatus can read information from the read-only storage area, and data can be recorded in the writable storage area using an apparatus obtained by minimally changing an existing recording/reproducing apparatus while maintaining the physical recording characteristics of the existing recording/reproducing apparatus.

Optical recording medium having read-only storage area and writable storage area and recording/reproducing apparatus and method therefor

A method for generating additional information for guaranteeing seamless playback of data streams, a recording medium for storing the information, and recording, editing and/or playback apparatus using the same are provided. The method generates additional information for guaranteeing seamless playback. The method includes a step of generating data stream information for each of two or more data streams, which includes packet data to which information on an arrival time of the respective packet data is added. The data stream information includes seamless playback information, which indicates whether a corresponding data stream is to be seamlessly reproduced after playback of a preceding data stream, and/or seamless time control information for controlling an output time of the corresponding data stream to be seamlessly reproduced. Therefore, data streams can be seamlessly reproduced without interruption between the data streams, by using data stream information which includes seamless information and/or seamless time control information including reference time, an offset value and/or a gap length value. Especially, by using the information structure, even if data streams are edited, the data streams can be seamlessly reproduced in such a simple manner of just modifying data stream information, instead of directly rewriting or modifying arrival time information which is added to packet data.

Method for generating additional information for guaranteeing seamless playback between data streams, recording medium storing the information, and recording, editing and/or playback apparatus using the same

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.

An apparatus reproduces AV data in an interactive mode, a method handles a user input, and an information storage medium stores information therefor. The information storage medium includes AV data and a markup document utilized to reproduce the AV data in an interactive mode. The markup document includes first event information of an occurrence of a key input event corresponding to a user action to inform, by default, an AV playback engine, which plays back the AV data. Accordingly, interactive contents may be controlled using a limited user input device.

Apparatus for reproducing AV data in interactive mode, method of handling user input, and information storage medium therefor

A method of and an apparatus for efficiently navigating a plurality of contents which are reproduced in a device for reproducing interactive contents, such as a computer, a DVD player, a PDA, or a cellular phone, by using a device having a limited number of input keys. Focusing layer values are allotted to contents elements to form focusing layers and the contents elements included in any one focusing layer are provided to a user. The focusing is moved when a command to move the focusing is input from the user. Accordingly, any kind of media storing interactive contents formed by using markup language is navigable using the device having the limited number of input keys, such as a television remote controller.

Multi-layer focusing method and apparatus therefor

Information storage medium having multi-angle data

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.
