摘要:
Text subtitle streams are reproduced based on register values contained in one or more player status registers included in a player. A SubPlayItem, which designates at least one text subtitle stream and is included in a PlayList recorded on a recording medium, is read. A first register value specifying one of the at least one text subtitle stream is stored in a first player status register included in the player. Next, a second register contained in a second player status register included in the player is read to determine whether the player is capable of decoding text subtitle streams. If the player's decoding capability is indicated, the text subtitle stream specified by the first register value is decoded.
摘要:
A method and a text subtitle decoder for decoding a text subtitle stream recorded on a recording medium are disclosed. A subtitle loading buffer initially loads a text subtitle stream including a dialog style segment defining a group of region styles and a dialog presentation segment having dialog presentation information and dialog text data for a dialog having at least one region. A text subtitle processor parses the dialog presentation segment into composition information, rendering information, and the dialog text data for each region. Next, a text renderer renders the text strings into a bitmap object for each region according to the rendering information, and the rendered bitmap object is composed in a graphics plane.

A recording medium includes a data area which stores at least one text subtitle stream. Each text subtitle stream includes text data to be displayed within a text subtitle region, region style information specifying a region style of the text subtitle region including an overall style of the text data, and inline style information for applying a different style to a specific portion of the text data within the text subtitle region.
摘要:
A text subtitle decoder includes a text subtitle processor, a text renderer, and a presentation controller. The text subtitle processor parses a text subtitle stream into text data and reproduction control information, where the text data represent a subtitle text to be displayed within a text subtitle region. After the text subtitle stream is parsed, the text renderer renders the text data into bitmap data using the reproduction control information. The presentation controller controls operations of the text subtitle processor and the text renderer.

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.

A recording medium, a method of controlling a file of the recording medium, and a method and apparatus for reproducing the same are disclosed. The recording medium includes at least one data area storing an original file system, which includes original data files, at least one normal file designating at least one of the original data files, and at least one remote file designating at least one additional data file, the at least one additional data file being required to be downloaded from an external source in order to play-back the at least one remote file.

A recording medium, a method of creating a file of the recording medium, and a method and apparatus for reproducing the same are disclosed. In the recording medium including a plurality of recording layers, the method of creating a file of the recording medium includes continuously recording a stream data file within a first recording layer and a second recording layer among the plurality of recording layers, which are adjacent to one another, and forming a PlayList file so as to enable seamless playback of the recorded stream data file, wherein the PlayList file includes a presentation start time (IN-Time), at which playback begins, positioned in the first recording layer, and a presentation end time (OUT-Time), at which playback is ended, positioned in the second recording layer.

A method of creating a playback control file for a recording medium and a method and apparatus for reproducing data using the playback control file are disclosed. The method of creating a playback control file for a recording medium includes creating a virtual stream file designating a group of stream files recorded on the recording medium, and creating a PlayList being able to reproduce the group of stream files, individually or in combination, the PlayList including a PlayItem directly designating the virtual stream file and identification information designating at least one of elementary streams included in the group of stream files.
摘要:
The recording medium stores a transport stream formed of packets. The packets represent one or more PES packets and are grouped into units of a fixed number of packets. A first portion of each unit corresponds to a first portion of a PES packet.
