摘要:
A storage medium in which audio-visual data with event information is recorded, and a reproducing apparatus and reproducing method thereof, includes: audio-visual (AV) data; and event information to activate an event when a predetermined specific scene is reproduced while reproducing the AV data and to execute a predetermined program application corresponding to the activated event by synchronizing the program application with the specific scene. Accordingly, the storage medium may be controlled so that an application having a program function is synchronized with a specific scene of the AV data using the event information while reproducing the entirety of the AV data or a portion of the AV data.

A multimedia data recording apparatus, a multimedia data reproducing apparatus, and multimedia data storage include a first layer storing multimedia data; and a second layer in which, when the multimedia data is divided into a record unit and a reproduction unit, information of attributes of the record unit and a relationship between the record unit and the reproduction unit are described with a markup language using elements and the attributes. Navigation data, which is used to control a selection of the reproduction unit and reproduction sequence, is recorded on a third layer.
摘要:
A storage medium for recording subtitle information based on text corresponding to moving picture data having a plurality of playback routes and an apparatus for and a method of reproducing an image including subtitles corresponding to the data. The storage medium includes moving picture data having a plurality of playback routes; a plurality of subtitle data items corresponding to the playback routes and supporting random search for a subtitle; and mapping information linking the moving picture data and the subtitle data. Accordingly, compatibility with a bitmap image method that is a subtitle processing method of a DVD or a bluray disc can be maintained, and multiple story playback is enabled. When random search or playback is performed, the search time for subtitle data is reduced such that search efficiency is enhanced.
摘要:
An information storage medium storing subtitle text-based information, and a method and apparatus utilizing same, process a subtitle. The information storage medium includes: dialog information which contains script text information of the subtitle and information specifying an output type of the script text; and presentation information which contains style information used to convert the script text into a bitmap format through rendering. With this structure, the amount of data required for a subtitle and the amount of data that should be processed when a subtitle is output may be greatly reduced.
摘要:
A recording medium for storing real time recording/reproduction information, a real time recording and reproducing method and apparatus, and a file operating method using the information. Real time recording/reproduction information for ensuring real time recording/reproduction is stored in a file control information area, in each real time file, or in a separate file, and real time recording/reproduction attributes are assigned to the file. Thus, real time recorded files can be continuously reproduced without interruption. Also, there are methods of creating a file to which real time recording/reproduction attributes are assigned, extending a data area, and recording and reproducing the file to which real time recording/reproduction attributes are assigned.

Provided are a multimedia data decoding apparatus, a method of receiving audio data using an HTTP protocol and an audio data structure used for the apparatus and method. The multimedia data reproducing apparatus comprises a decoder receiving AV data, decoding the AV data, and reproducing the AV data in synchronization with predetermined markup data related to the AV data; and a markup resource decoder receiving location information of video data being reproduced by the decoder, calculating a reproducing location of the markup data related to the video, and transmitting the reproducing location of the markup data to the decoder. Audio data is received using the HTTP protocol, not a complex audio/video streaming protocol, and is output in synchronization with video data.

An information storage medium which stores data structures supporting multi-angles includes clip AV streams for respective angle data of multi-angle motion picture data. As additional information for each clip AV stream, clip information is recorded on a separate storage area from that of the clip AV streams. The clip information includes jumping-point information for jumping into another angle. Each of the clip AV streams may be recorded in a contiguous recording area, or divided into smaller interleaved units that are interleaved with units of the other clip AV streams.
摘要:
A data storage medium in which multiple bitstreams are recorded, an apparatus and method for recording the multiple bitstreams, and an apparatus and method for reproducing the multiple bitstreams are provided. The reproducing apparatus includes: a reading unit for reading main data including audio data and/or video data, and reading sub data recorded in a separate bitstream from the main data, which is later reproduced in synchronization with the main data; and a multiplexer for multiplexing the main data and sub data read by the reading unit. Therefore, multiple bitstreams can be read and reproduced at the same time.
摘要:
A method of accelerating graphic display, including: interpreting graphic data; converting the graphic data into at least one simplified accelerating command data and storing the data; and displaying a graphic image by executing at least one stored accelerating command data. The storing and the displaying are performed independently.
