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.

Recording medium for storing real time recording/reproduction information, method and apparatus for recording and reproducing in real time, and file operating method using the same

A method and apparatus for creating a LastURI (uniform resource identifier) of a content asset in order to share the content asset based on a multiphoto video (MPV) file in content recorders and/or reproducers having different file systems, and a recording medium storing program for executing the method are provided. The method creates one of an absolute LastURI and a relative LastURI as the LastURI of the content asset according to protocol type information, so that content recorders and/or reproducers using different file systems can easily find and share the content asset based on the MPV file.

Method and apparatus for creating last uniform resource identifier, and recording medium storing program for executing the method

A recording medium storing information indicating that linking is applied immediately after the defective area, distinguishing a linking type which occurs in a general incremental recording mode from a linking type which occurs after the defective area. Defective areas are detected and registered in a predetermined area (recording management data (RMD) area) before user data is recorded or while user data is being recorded in the recording medium having a plurality of continuous basic recording units, such as a digital versatile disc-rewritable (DVD-RW) in which recording and reproducing can be done repeatedly. Linking is not only applied in an incremental recording mode or in a restricted overwrite recording mode, but linking is also applied to an area immediately after the defective area which is registered in the defect list, increasing reliability of the user data.

A cyclic referencing management method and apparatus, a parsing method and apparatus, and a computer readable recording medium storing a program to implement the methods are provided. The method for managing cyclic referencing that may occur by mutual references of assets in a file provided to control assets in a multimedia application environment, includes: detecting an asset generating cyclic referencing; and ignoring the asset generating cycling referencing. According to the methods and apparatuses, cyclic referencing that can occur in a file to control assets can be detected and processed such that the system can be prevented from entering an indefinite loop or causing an erroneous operation.

A recording medium storing linking type information and a method of processing a defective area in the medium. The recording medium stores information indicating that linking is applied immediately after the defective area, distinguishing a linking type which occurs in a general incremental recording mode from a linking type which occurs after the defective area. Defective areas are detected and registered in a predetermined area (recording management data (RMD) area) before user data is recorded or while user data is being recorded in the recording medium having a plurality of continuous basic recording units, such as a digital versatile disc-rewritable (DVD-RW) in which recording and reproducing can be done repeatedly. Linking is not only applied in an incremental recording mode or in a restricted overwrite recording mode, but linking is also applied to an area immediately after the defective area which is registered in the defect list, increasing reliability of the user data. In addition, a test signal such as data, a groove wobble pattern, or a recording mark which has a test pattern, which functions as linking data is recorded in advance in a block immediately after the defective area detected during certification. If the test signal is detected after the defective area, the new user data is recorded immediately after a predetermined number of error correction code (ECC) blocks following the defective area without using linking, reducing the time for recording linking data, which is advantageous to real-time recording.

An optical recording medium on which data may be stored seamlessly, and a method of processing a defective area in the optical recording medium are provided. In a recording medium in which basic recording units are seamlessly recorded, such as a digital versatile disc rewritable (DVD-RW) on which data can be repeatedly recorded and reproduced multiple times, defective areas occurring before or during use are detected, and a list of the defective areas is recorded in a predetermined area of the recording medium. Thereafter, while user data is being recorded, instead of slipping (lowering optical power in) the defective areas registered in the defective area list, dummy data is recorded in the defective areas, basic unit data from an area preceding or succeeding a defective area is repeatedly recorded in the defective area, or a predetermined data pattern is recorded in the defective area. This suppresses linking caused by the interruption of data recording, thereby ensuring a maximum user area.
