摘要:
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 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 method for determining type information of a recording medium includes the steps of: a) determining type information of a recording medium classified according to position information of a recording layer contained in the recording medium; and b) determining type information of at least two recording mediums having the same recording layer position on the basis of the presence or absence of a signal reflected from a specific area contained in a recording-medium inner side. Therefore, the method can be applied to a fabrication process of a new optical recording/reproducing device for a high-density recording medium, and can effectively record/reproduce data in/from the recording medium.

The present invention relates to a method for managing menu data of data stream recorded on an optical disc such as a high-density read-only optical disc. A read-only recording medium including menu data in accordance with the present invention is characterized in that its menu data contains at least one menu page picture in which a menu item is included, wherein said menu data contains item differentiating information that is used to differentiate one menu item from another in a displayed menu page picture. Owing to such constructed menu data, a menu page is constructed very fast.

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.

The present invention relates to a method of conducting management operations such as deletion, copy, and movement of recorded still pictures recorded on a recording medium. The present method records still pictures onto a recording medium, groups the recorded still pictures based on their attributes, creates a list listing filenames of respective still pictures belonging to each still-picture group, and writes the filename list onto the recording medium. Afterwards, if a deleting or an inter-group moving command is received for a still picture recorded on the recording medium, the present method deletes a filename of the still picture written on the filename list including the filename of the still picture. Such a still picture managing method through a filename list ensures that moving, copying, and deleting operations of numerous recorded still pictures can be conducted easily.

A recording medium having a data structure for managing reproduction of video data recorded on the recording medium. The recording medium having at least one navigation area for storing navigation management information used in managing real-time reproduction path video data recorded on the recording medium. The navigation management information includes at least one navigation unit that includes a plurality of video data packets and a plurality of real-time navigation packets.
摘要:
In one embodiment, at least one supplementary data stream related to a main data stream is downloaded. A stream table defining reproducible data streams, in which a reproducing apparatus selects at least one data stream to be reproduced during presentation of a playitem and a subplayitem, is checked. The playitem manages reproduction of the main data stream and the subplayitem manages reproduction of the downloaded supplementary data stream. The main and downloaded supplementary data streams defined in the stream table are reproduced.
摘要:
A recording medium, and a method and apparatus for reproducing data from the recording medium are disclosed. A disc package for effectively reproducing data having different attributes recorded in the recording medium, and a method and apparatus for reproducing data of the recording medium and data downloaded from a content provider (CP) are disclosed. A first case in which the CP transmits an updated management file, and a second case in which a disc player forms an updated management file are disclosed.
摘要:
A recording medium, and a method and apparatus for reproducing data from a recording medium using a local storage is disclosed. The recording medium includes: a first area for storing content data; and a second area for storing first identification (ID) information capable of identifying a content provider (CP) and second identification (ID) information capable of identifying the corresponding recording medium manufactured by the content provider (CP). The method for reproducing data from a recording medium using a local storage includes the steps of: a) reading a directory name for identifying a content provider recorded in the recording medium and a directory name for identifying the recording medium; b) recognizing a binding unit contained in a local storage directory having the same directory name as the read directory name; c) binding the binding unit with files contained in the recording medium, and forming a virtual package; and d) reproducing content data stored in the recording medium and content data stored in the local storage using the virtual package.
