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 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.

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

A method for reproducing data recorded on an interactive recording medium in conjunction with associated auxiliary data is disclosed. An interactive recording medium reproducing apparatus reproduces A/V data recorded on an interactive recording medium such as an interactive DVD in conjunction with contents data provided by a contents providing server using navigation information for the contents data also provided by the contents providing server, thereby allowing synchronized reproduction of data from different sources.

Method for reproducing data recorded on an interactive recording medium in conjunction with associated auxiliary data

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.

Recording medium containing supplementary service information for audio/video contents, and method and apparatus of providing supplementary service information of the recording medium

In the data structure of recording medium for managing sound data associated with graphic information, an interactive composition segment is provided. The interactive composition segment includes sound management information. The sound management information is associated with a graphic item and provides an identifier of a sound data in sound file, separate from a main data file, to reproduce in association with the graphic item.

Recording medium having a data structure for managing sound data and recording and reproducing methods and apparatus

The 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.

A non-transitory computer readable recording medium and method and apparatus for reproducing and recording text subtitle streams including a style segment and presentation segments. The style segments define a region style, and each presentation segment contains a region subtitle associated with a region subtitle and presentation time information defining a presentation time of a corresponding presentation segment. The recording medium and method allow text subtitle streams to be more efficiently and effectively reproduced and recorded.

Recording medium storing a text subtitle stream including a style segment and a plurality of presentation segments, method and apparatus for reproducing a text subtitle stream including a style segment and a plurality of presentation segments

A method for connecting a media player to a remote server is provided. The method comprises processing a request for connecting to an remote server while reproducing data recorded on an enhanced navigation medium, processing connection information recorded on the enhanced navigation medium to determine whether connection to the remote server is permitted, and requesting connection to the remote server, if connection to the remote server is permitted in accordance with the connection information.
