A recording medium, a method for determining type information of a recording medium, and a method and apparatus for recording/reproducing data in/from the recording medium using the method are disclosed. The recording medium sequentially includes a lead-in area, a data area, and a lead-out area on the basis of an inner side. The data area and the lead-out area are designed to be read by a blue-ray optical beam. The lead-in area includes a first area readable by a red-ray optical beam and a second area readable by a blue-ray optical beam. Therefore, the recording medium can be applied to a fabrication process of a new optical recording/reproducing device for a high-density recording medium, and data can be effectively recorded/reproduced in/from the recording medium.

A method and apparatus for managing data files of a local storage is disclosed. The method for managing data files of a local storage includes the steps of: a) downloading at least one data file from a content provider, storing the downloaded data file in the local storage, and forming a binding unit using the stored file; and b) upon receiving a command for deleting a specific file contained in the binding unit, deleting all files contained in the binding unit, deleting all files associated with a title including a specific file to be deleted, or deleting only the specific file to be deleted.

A method and apparatus for reproducing data from a recording medium using a local storage is disclosed. A method and apparatus for downloading data associated with the recording medium from an external part, and reproducing the downloaded data is disclosed. A binding unit combined with the recording medium from among the downloaded data of the local storage is formed, and is combined with files of the recording medium using the binding information, such that the virtual package is formed. Data of the recording medium and/or data of the local storage are reproduced by the virtual package. If a specific file contained in the binding unit is equal to a specific file contained in the recording medium when the virtual package is formed, priority is assigned to the file of the binding unit so that the virtual package is formed. Therefore, data of the recording medium and data of the local storage can be effectively reproduced at the same time, resulting in greater convenience of a user.

A method and apparatus for reproducing data from a recording medium using a local storage is disclosed. The method for reproducing data of a recording medium using a local storage includes the steps of: a) reading a binding unit associated with a specific recording medium from the local storage; b) performing a binding operation for combining the binding unit with a file structure contained in the recording medium, and forming a virtual package including a playlist file capable of allowing a plurality of clips to be reproduced by a single playitem; and c) reproducing data stored in the recording medium and/or data stored in the local storage using the formed virtual package. Therefore, the original data recorded in the recording medium and the additional data stored in the local storage can be effective reproduced, resulting in greater convenience of use.

An apparatus for reproducing data recorded on a recording medium includes a pick-up unit, a local storage, and a decoder. The pick-up unit reads main data recorded on the recording medium, and the local storage stores sub data associated with the main data. The sub data may include interactive graphic streams or text subtitle streams. The decoder decodes the main data and the sub data using a PlayList which includes a main path and a sub path. The main path contains a PlayItem for play-back of the main data, and the sub path contains at least one SubPlayItem associated with the PlayItem for play-back of the sub data in association with the play-back of the main data. The PlayList file further includes sub path type information which indicates whether the SubPlayItem included in the sub path is synchronized with the PlayItem.
摘要:
A recording area of an example recording medium stores a text subtitle stream that includes a dialog style segment and at least one dialog presentation segment associated with the dialog style segment. The dialog style segment includes at least one set of style information. Each set of style information provides region positioning information for positioning a region in an image and text box positioning information for positioning a text box in the region. The dialog presentation segment includes at least one region subtitle information. The region subtitle information includes text subtitle data (e.g., style data and/or text string data) and a region style identifier, and the region style identifier identifies one of the sets of style information in the dialog style segment to apply to the text subtitle data.
摘要:
A recording medium, method, and apparatus for reproducing text subtitle streams are disclosed. A microcomputer initially reads a set of PlayItems and a SubPlayItem included in a PlayList which is recorded on a recording medium, and it further reads synchronization information included in the SubPlayItem. Each PlayItem is configured to reproduce at least one main AV stream, and the SubPlayItem is configured to reproduce a text subtitle stream. The synchronization information indicates a presentation start time of the SubPlayItem on a global time axis of the PlayList. When the PlayList is randomly accessed at a random access time on the global time axis, the microcomputer calculates a corresponding access time on a time axis of the SubPlayItem. Then a text subtitle decoder decodes for presentation a dialog presentation segment with the closest dialog start time after the corresponding access time on the axis of the SubPlayItem.
摘要:
In the data structure for managing reproduction of various data streams, a playlist includes at least one playitem and at least one subpath. The playitem includes management information for managing reproduction of main data recorded on the recording medium, and the subpath includes at least one subplayitem. The subplayitem includes management information for managing reproduction of supplemental data recorded on the recording medium, and the subplayitem includes a synchronization data field for providing synchronizing information to synchronize reproduction of the supplemental data with reproduction of the main data. Also, the subpath includes a type indicator that indicates the type of the supplemental data managed by the subpath and signifies whether the synchronizing information is valid.
摘要:
In the data structure for managing font information for text subtitles, a clip information file for a text subtitle stream is provided. The clip information file includes a font file name field for each font file associated with the text subtitle stream. The font file name fields are indexed by a font identifier for each font file associated with the text subtitle stream, and each font file name field provides the font file name of the font file identified by the font identifier. In one embodiment, at least one of the font identifiers identifies a font file referenced as style information in the text subtitle stream.
