A method and an apparatus for retrieving information for managing video data involving link information associating metadata with the video data. A metadata indicator is used to indicate that metadata exists in a stream with the linking information. Link information also associates the metadata with location information to identify where additional information on the video data, which is described by the metadata, may be found. Using the method or apparatus, a single metadata unit is able to be associated with a plurality of video data units, or a plurality of metadata units are able to be associated with a single video data unit, in order to provide more information on the video data.

Recording medium containing moving picture data and additional information thereof and reproducing method and apparatus of the recording medium

In the method, video data is reproduced from the recording medium, and an I-picture and a number of P-pictures are output as a still picture based on the reproduced video data. The output data may then be received and decoded for display.

Method of reproducing a still picture from a recording medium, method of decoding the still picture and the recording medium

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.

Method and apparatus for retrieving metadata for managing video data

The recording medium has a navigation area storing at least one navigation file. The navigation file includes navigation commands for managing reproduction of at least video data forming different parental control reproduction paths.

Recording medium having data structure for managing reproduction of at least video data recorded thereon and recording and reproducing methods and apparatuses

The recording medium has a data structure for managing reproduction of data recorded on the recording medium. A navigation area stores at least one navigation file, and the navigation file includes at least one navigation command group. At least one navigation command group includes at least one navigation command for managing reproduction of at least video data recorded on the recording medium.

A recording medium, method and apparatus for managing data are discussed. According to an embodiment, the present invention provides a method of reproducing main data and additional data. The method includes receiving the additional data associated with the main data, the additional data being divided into a plurality of segment units; and reproducing the additional data in a synchronous manner with the main data using time information if indication information indicates a presence of the time information. The time information indicates a presentation time of the additional data with respect to the main data. The main data and the additional data are reproduced according to management data, the management data including link information for linking the main data and the additional data.

Method for ensuring synchronous presentation of additional data with audio data

A recording medium, a method of creating a file of the recording medium, and a method and apparatus for reproducing the same are disclosed, wherein position change and transition of random playback points among title recorded within the recording medium can be easily performed, thereby providing an apparatus having more convenient title playback functions to the users. The method of creating a file of the recording medium includes forming a PlayList file including playback control information of a set of recorded data, forming an object file including an execute command of the PlayList file, and forming an index file including a set of Normal Title information designating a specific object within the object file, and a set of auxiliary Title information designating a random point of data being reproduced by the Normal Title information.

Recording medium, method of creating file of the recording medium, and method and apparatus for reproducing the same

The recording medium includes a data structure with at least one playlist file stored in a playlist area of the recording medium. The playlist file includes at least one playitem, at least one sub-playitem and mark information. The playitem provides navigation information for reproducing at least one still picture from a first file. The sub-playitem is associated with the playitem and provides navigation information for reproducing audio data from a second file. The mark information includes at least one mark pointing to the still picture.

Recording medium having data structure for managing reproduction of still pictures recorded thereon and recording and reproducing methods and apparatuses

The present invention relates to method and apparatus of providing supplementary service information for A/V contents written in a recording medium. This method has a recording medium containing Presentation Language data, which have to be included like as in a digital television signal for supplementary service information in accordance with Advanced TV Enhancement Forum or Digital TV Application Software Environment standard, and reproduces, if a disk reproduction is requested, the Presentation Language data as well as requested A/V data and provides them for a connected external device such as a digital television. As a result, various video information and functions provided with Presentation Language data by a recording medium can be realized at a digital television set being able to accept Presentation Language data.
