A method for reproducing data from a recording medium in a player equipped with a network device (i.e., a Network Equipped Player) includes the steps of: a) if the recording medium is loaded, transmitting network configuration information and identification (ID) information of the loaded recording medium to a content provider (CP); b) downloading data associated with the recording medium from the content provider (CP) over a network; and c) reproducing data transmitted over the network and data recorded in the recording medium.

Abstract: The present invention relates to a method and apparatus of determining arrival time of data packet when a digital broadcast data stream is recorded. According to the present invention, two program clock reference values are extracted from a transport packet sequence, an average packet interval time is obtained based on both the difference between the two program clock reference values and the number of packets between two packets from which the two program clock reference values are extracted, and an arrival time of each packet between the two packets is determined by t(0)+I*t_av, where t_av is the average packet interval time, t(0) is the program clock reference value of the preceding one among the both packets, and I is an index indicative of the order of packet between the both packets.

Abstract: A structure of navigation information for video data recorded on a recording medium and recording and reproducing methods and apparatuses using the structure. The method of recording video data in accordance with the present invention records video data on a recording medium with organizing the video data into navigation units and interleaving navigation units of different reproduction paths with one another in multiple reproduction path segments. An information entry is created for each navigation unit and the information entry comprises information indicating whether the associated-navigation unit is in a multiple reproduction path segment and information for identifying the reproduction path to which the associated navigation unit belongs.

Abstract: The present invention relates to editing data streams recorded in a recording medium. At the time of deleting an arbitrary navigation unit from a data stream partitioned by the navigation units and recorded in a recording medium, information is recorded in the recording medium, which, in a recording block including both remaining data belonging to the deleted navigation unit and valid data belonging to the navigation unit right before the deleted navigation unit, the information is used for distinguishing the valid data from the remaining data. By referring to the information afterwards, the remaining data can be prevented from being decoded.

Abstract: A computer readable medium is provided having a data structure for managing reproduction of a slideshow of still images recorded on the computer readable medium. The computer readable medium includes a clip information area and/or a playlist area. The clip information area stores at least one clip information file. Each clip information file is associated with at least one stream file stored in a data area. The clip information file provides a map for the associated stream file. Each map maps presentation time information to address information for the associated stream file. The playlist area stores a playlist file. The playlist file references the clip information file and includes navigation information for reproducing still images and audio data together as a slideshow.

Abstract: The recording medium includes at least one data area storing more than one clip of video data for at least one segment of a title, and each clip of video data is associated with a different reproduction path of the segment.

Abstract: 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.

Abstract: The recording medium includes a data area storing one or more graphic segments, each of which includes graphic data, multiplied with other data.

Abstract: The recording medium includes a navigation area having navigation information recording therein. The navigation information indicates a portion of a clip file, which includes video data, to display as a still image and a duration to display the still image.

Abstract: In one embodiment, the method includes retrieving management information associated with audiovisual data. The management information includes location information, an indicator, and reference information. The method further includes identifying whether or not a set of additional data associated with the audiovisual data exists in a stream including at least a portion of the management information using the indicator, the additional data being describing the audiovisual data. The indicator includes one of a first indicator value indicating that the set of the additional data associated with the audiovisual data exists in the stream and a second indicator value indicating that the set of the additional data associated with the audiovisual data does not exist in the stream.

Abstract: A buffer initially preloads a text subtitle stream recorded on a recording medium. The preloaded text subtitle stream includes a dialog style segment defining a group of region styles and a plurality of dialog presentation segments, each of which contains at least one region of dialog text. Each region of dialog text is linked to a selected one of the group of region styles defined in the dialog style segment. The dialog style segment and the plurality of dialog presentation segments are encapsulated in a plurality of PES packets, respectively. A text subtitle decoder decodes and presents each dialog presentation segment according to a continuous presentation flag included in each dialog presentation segment. The continuous presentation flag indicates whether continuous presentation is required for each dialog presentation segment with previous one.

Abstract: A user data area of the recording medium is at least partially divided into separate recording areas such that data recorded in a separate recording area is of a same type. For example, at least one of the separate recording areas may be storing managing information for managing the recording medium. Additionally, at least two separate recording areas may be for recording different types of data. For example, at least one of the separate recording areas may be storing managing information for managing the recording medium, and at least another one of the separate recording areas is for storing a copy of the data in the at least one of the separate recording areas for storing management information.

Abstract: The computer readable medium stores an executable data structure for managing reproduction of text by a reproducing apparatus. The data structure includes at least one text subtitle stream having a style segment and at least one presentation segment. The style segment defines a group of region styles, and the presentation segment contains at least one region of text. The region of text is linked to a selected one of the group of region styles defined in the style segment by an identifier. The style segment and the at least one presentation segment are encapsulated into respective PES packets. The presentation segment contains a continuous presentation flag indicating whether continuous presentation is required for the presentation segment with a previous presentation segment. A presentation start time of the presentation segment is equal to presentation end time of the previous presentation segment when continuous presentation is required for the presentation segment with the previous presentation segment.
