The title management information includes at least one segment that is associated with at least one playlist in the playlist directory area, and each playitem in the playlist is a unit to be randomized or shuffled during random/shuffle reproduction mode.

Abstract: A method and apparatus for reproducing video data are discussed.

Abstract: The present invention relates to a data structure for managing to resume reproduction of data including at least video data recorded on a recording medium. A recording medium having the data structure has data recorded thereon that comprises: at least one data playing unit (title or movie object) including at least video data; and navigation information for managing the data playing unit, wherein the navigation information includes control information to indicate whether resumption of the data playing unit is permitted or not.

Abstract: The recording medium includes at least one navigation area storing navigation management information for managing reproduction of the multiple reproduction path video data recorded on the recording medium. The navigation area has a plurality of angle change recording information corresponding to each of a plurality of data blocks.

Abstract: The data structure on the recording medium includes a navigation area storing an information file. The information file includes a first playback indicator that identifies a navigation command field for execution at first playback of the recording medium. The identified navigation command field is also stored on the recording medium, and the identified navigation command field includes at least one navigation command.

Abstract: The present invention relates to a data structure for managing reproduction of at least video data having multiple reproduction paths through title structure. A recording medium having a data structure according to the present invention comprises a data area storing multi-path video data; and a management information area storing title management information to assign a plurality of titles to the multi-path video data, wherein the title management information includes at least one title block that is composed of an entry title and at least one non-entry title that are associated with mutually different reproduction paths.

Abstract: The present invention relates to a recording medium containing moving picture data and additional information thereof and to reproducing method and apparatus of the recording medium. The present recording medium has script files including additional information about moving picture data, e.g., scene descriptive text and introduction of characters, etc. In addition, information linking each script file with a section of moving picture data to be presented with contents of the script file is included in a link data file or is contained in a filename of the script file. In reproduction of the recording medium, a script file linked with presently reproduced moving picture data section is determined and searched for based on the link data file or every filename of the script files, and contents of the found script file are presented together with the presently reproduced moving picture data. Furthermore, previously presented additional information is removed depending on data or filename of the found script file.

Abstract: In one embodiment, the method includes retrieving management information associated with audiovisual data. The management information includes location information, an indicator, and reference information. The method further includes identifying whether or not a set of additional data associated with the audiovisual data exists in a stream including at least a portion of the management information using the indicator, the additional data being describing the audiovisual data. The indicator includes one of a first indicator value indicating that the set of the additional data associated with the audiovisual data exists in the stream and a second indicator value indicating that the set of the additional data associated with the audiovisual data does not exist in the stream.

Abstract: The present invention relates to a method for recording and managing a multi-channel broadcast stream. The present method records on a recording medium such as a BD-RW a multi-channel broadcast stream where a plurality of channels are multiplexed, and creates and records management information for individual search and reproduction control of the plural channels. Consequently, this method ensures fast random access and various trick play of individual subchannel streams multiplexed in a recorded multi-channel stream at user's request.

Abstract: In accordance with one embodiment of the invention, a recording medium comprises a first recording area for recording data streams of a title domain and menu domain, said title domain comprising a plurality of titles, and a second recording area for recording navigation information for control of reproduction of the data streams, wherein the navigation information in the second recording area comprises playback control information for designating a location in the title domain to be resumed.

Abstract: A recording medium having a data structure for managing additional content data of main data recorded thereon in accordance with the present invention comprises a data area storing at least one clip file including main data and/or additional content data of the main data; and a navigation area storing a clip information file including information to indicate whether the clip file includes additional content data.
