    摘要: A buffer initially preloads a text subtitle stream recorded on a recording medium. The preloaded text subtitle stream includes a dialog style segment and a plurality of dialog presentation segments. The dialog style segment defines a group of region styles and palette information. Each dialog presentation segment contains at least one region of dialog text, where each region of dialog text is linked to a selected one of the group of region styles defined in the dialog style segment. A text subtitle decoder reads a palette update flag included in each dialog presentation segment and presents each dialog presentation segment according to an indication of the palette update flag. The palette update flag indicates whether to use the palette information defined in the dialog style segment or to use new palette information when presenting each dialog presentation segment.

    摘要: 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.

    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.

    摘要: A recording medium and method and apparatus for reproducing and recording text subtitle streams are disclosed. A PlayList file contains a set of PlayItems and a SubPlayItem. Each PlayItem is configured to reproduce at least one main AV stream, and the SubPlayItem is configured to reproduce at least one text subtitle stream. The PlayList file further contains synchronization information which indicates a presentation start time of the SubPlayItem within a playing time interval of one of the set of PlayItems. The PlayList file, main AV stream, and text subtitle streams are recorded on a recording medium. Each text subtitle stream includes a plurality of dialog presentation segments, each of which includes at least one region of dialog text.

    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: The present invention relates to multi-channel stream recording/reproducing method and apparatus. The present multi-channel stream reproducing method checks whether or not reproduced multi-channel stream belongs to same broadcast (RF) channel, and deletes PSI (Program Specific Information) packets included in channel stream excluding one channel stream if it belongs to same RF channel, and makes new PSI packets with reference to PSI packets included in reproduced multi-channel stream to replace them, if not. Furthermore, the present method compensates appropriately PCRs (Program Clock References) included in channel stream excluding one channel stream in case of the latter. The present method enables a digital TV set to present multi-channel stream simultaneously in PIP (Picture-In-Picture) or multi-screen mode with no error in channel selection and presentation (or decoding) time.
