摘要:
In one embodiment, the recording medium includes a management area storing management information. The management information includes navigation information for reproducing data from the recording medium, and the navigation information including region information. The region information indicates at least one geographic region in which reproduction of the data is permitted.

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 the type information of the 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 a reflection signal received via a track cross operation. 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 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.

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.

A method of presenting auxiliary data for an interactive recording medium is disclosed. In an interactive recording medium reproducing apparatus that reproduces A/V data and contents data recorded on an interactive recording medium and contents data provided by a contents providing server, the contents data provided by the contents providing server is presented appropriately according to the attributes of the contents data by using attribute information for the contents data.

In one embodiment, the method includes determining which one of a primary subtitle associated with a primary video stream and a secondary subtitle associated with a secondary video stream to display based on management information stored in a memory. The secondary video stream represents the picture-in-picture presentation path with respect to a primary presentation path represented by the primary video stream. The primary video stream is recorded on a recording medium. The determined subtitle is selectively reproduced based on the management information.
摘要:
In one embodiment, a primary video stream in data reproduced from the recording medium is decoded using a first decoder, and a secondary video stream in the reproduced data is decoded using a second decoder. The secondary video stream represents picture-in-picture video data with respect to the primary video stream.
摘要:
In one embodiment, a primary video stream and a secondary video stream are stored in a data area of the recording medium. The primary video stream represents a primary presentation path, and the secondary video stream represents a picture-in-picture presentation path with respect to the primary presentation path. Management information for managing reproduction of the picture-in-picture presentation path is stored in a management area of the recording medium. The management information indicates a type of the secondary video data stream based on whether the secondary video data stream is multiplexed with the primary video data stream.
