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.

A method of recording and reproducing video data is provided. The method of recording video data in an information storage medium includes the steps of (a) decoding originally encoded video data, (b) re-encoding the decoded video data in a different way to the originally encoded video data, (c) generating video transform information which is to be referred to for decoding the video data into its original state, and (d) recording the generated video transform information and the re-encoded video data in the information storage medium. Accordingly, the video data can be properly reproduced even if it is re-encoded in a different way to the originally encoded video data.

An information storage medium storing subtitle text-based information, and a method and apparatus utilizing same, process a subtitle The information storage medium includes: dialog information which contains script text information of the subtitle and information specifying an output type of the script text; and presentation information which contains style information used to convert the script text into a bitmap format through rendering. With this structure, the amount of data required for a subtitle and the amount of data that should be processed when a subtitle is output may be greatly reduced.

A method of storing multi angle data. Data for a plurality of angles of a scene are stored in interleaved blocks. Sizes of the interleaved blocks are integral multiples of sizes of integral numbered aligned units that include packets. Angle change points are included in each of the interleaved blocks, allowing a reproducing apparatus to seamlessly jump from one angle to another angle during reproduction of the multi angle data. A number of the angle points recorded on the information storage medium is computed so that a jumping distance required by the data during reproduction does not exceed a maximum jumping distance of a reproducing apparatus.

A storage medium for storing text-based subtitle data including style information, a reproducing apparatus and methods are provided for reproducing text-based subtitle data including style information separately recorded on the storage medium. The storage medium includes: multimedia image data; and text-based subtitle data for displaying subtitles on an image based on the multimedia image data, wherein the text-based subtitle data includes dialog information indicating subtitle contents to be displayed on the image, style information indicating an output style of the dialog information, and partial style information indicating an output style applied to a portion of the dialog information. Accordingly, subtitles can be provided in a plurality of languages without limited to the number of units of subtitle data. In addition, subtitle data can be easily produced and edited. Likewise, an output style of the subtitle data can be changed in a variety of ways. Also, a special style can be applied in order to emphasize a portion of the subtitles.

A method of reproducing moving-image information recorded on a storage medium, including: reading mode information from the storage medium including an object of a first type for reproducing the moving-image information, an object of a second type for providing additional functions related to the moving-image information, and system data for controlling the reproduction of the object of the first and second types, including: information indicating an object to be automatically reproduced when the storage medium is loaded, menu information for displaying a menu, and title information for each object of the first type and the object of the second type, the title information including identification information of the corresponding object, the mode information indicating the type of the corresponding object, determining the type of an object to be reproduced based on the read mode information, and reproducing the object based on the result of the determination.
摘要:
A method of processing images, the method including determining whether metadata for generating a depth map corresponding to a predetermined title exists for each of a plurality of titles recorded in a disk by using metadata for disk management, and including converting two-dimensional (2D) images in the predetermined title to three-dimensional (3D) images by using the metadata for generating the depth map if metadata for generating the depth map corresponding to the predetermined title exists.

An apparatus and method for reproducing a storage medium that stores metadata are provided for an enhanced search function using various search keywords of audio-visual (AV) data. The apparatus includes: a search unit for searching for scenes matching a search keyword by conducting an enhanced search function on the AV data with reference to metadata which contains information regarding at least one search keyword for each of the scenes of the AV data; and a reproducing unit for reproducing the AV data corresponding to at least one scene found by the search unit. The metadata may include information regarding an entry point and/or duration, angles, etc. of each scene. Hence, the enhanced search can be conducted using various search keywords. Further, search results can be reproduced according to diverse scenarios, and the enhanced search function can be provided for movie titles that support multiple angles or multiple paths. Moreover, metadata can be created in multiple languages, thereby enabling the enhanced search function to support multiple languages.
摘要:
A storage medium storing multimedia data for the reproduction of audio-visual (AV) data and a programming function, and a reproducing apparatus and method thereof. The storage medium includes: reproduction mode data for reproducing audio-visual (AV) data; program data including a plurality of program applications for providing interactive functions with a user and/or additional functions using the AV data; system data for controlling the execution of the reproduction mode data and the program data; and application objects for managing the execution of the program data and information on the reproduction mode data to be reproduced along with the execution of the program data. Accordingly, various user interfaces and/or various additional functions can be provided, as well as simple reproduction of AV data. Also the program application can be prevented from using malicious intent, and program applications having the same function can be reused without modification or recompilation.
