  • Patent number: 6779137
    Abstract: A method of verifying that defect management area (DMA) information is generated or updated normally when a disc recording and reproducing apparatus performs reinitialization with clearing of defect lists without certification, and a test apparatus therefore. The method includes performing reinitialization with clearing of a predetermined defect list existing in a DMA on a test disc in a recording and reproducing apparatus using a test disc with test reference information, and generating test information from the defect management information which is generated after the reinitialization; and comparing reference information expected from the test reference information with the test information to provide the result of verification of the test information.

  • Publication number: 20040158830
    Abstract: An apparatus and a method of executing an applet in an apparatus reproducing interactive contents. The method involves receiving a request for executing an applet from a browser, determining whether the applet is a bound applet or an unbound applet, and loading the applet into a virtual machine. If the loaded applet is an unbound applet, predetermined commands to the virtual machine are issued, so that the applet can fall into an ‘initiate’ state and into a ‘start’ state, respectively.

  • Patent number: 6775803
    Abstract: 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.

  • Publication number: 20040150637
    Abstract: A method and an apparatus displaying a markup document linked to an applet by delaying display of image output information for the markup document and synchronously displaying the delayed image output information for the markup document and an applet output when rendering of the applet is completed. The markup document linked to an applet is displayed by synchronizing the applet and the markup document outputs so that an initial blank applet image is not displayed while initializing and executing the applet. Accordingly, a user conveniently views a markup image linked to an applet.

  • Publication number: 20040138873
    Abstract: A method and apparatus for mixing audio streams, and an information storage medium that stores mixing information. The information storage medium includes at least one audio stream that contains a multiplicity of audio data obtained from respective multiple channels, and mixing information used to mix at least parts of the multiplicity of audio data. Accordingly, it is possible to mix and reproduce different types of channel components without changing the channel formats of different audio streams. Furthermore, it is also possible to perform dynamic mixing on multiple channel components, thus enabling adaptation to a change in audio content and characteristics thereof and thereby reproducing audio data more appropriately. In particular, since mixing information is described in interactive data allowing an interaction with a user, it is possible to provide the user with more applications.

  • Publication number: 20040131334
    Abstract: An apparatus reproduces AV data in an interactive mode, a method handles a user input, and an information storage medium stores information therefor. The information storage medium includes AV data and a markup document utilized to reproduce the AV data in an interactive mode. The markup document includes first event information of an occurrence of a key input event corresponding to a user action to inform, by default, an AV playback engine, which plays back the AV data. Accordingly, interactive contents may be controlled using a limited user input device.
