Abstract:
1. A method of managing additional data associated with main video data, the method comprising: storing file information and buffering information about the additional data in a buffer of a device for reproducing data from a recording medium; and storing the additional data associated with the main video data of the recording medium as a file of a prescribed format in the buffer of the device, wherein the file information includes a file name and a data type, and the buffering information includes information for specifying a position and a size of a buffering area to be allocated for storing the additional data before recording the additional data in the buffer of the device for reproducing data from the recording medium, the buffering information further including information for specifying an initial buffering size of the additional data, wherein when the additional data amounting to the initial buffering size is buffered in the allocated buffering area, the buffered additional data begins to be recorded or played, the size allocated to the buffering area being different from the initial buffering size of the additional data, wherein the additional data is stored in the buffer allocated according to the buffering information, wherein the position of the buffering area for storing the additional data is selectively decided according to the information for specifying the buffering area of the additional data, and wherein the position of the buffering area indicates a partial update area or a normal area in the buffering area in which the normal area and the partial update area are separately allocated.
