Patent ID: 8265454

Claim:
A video/audio playback apparatus comprising: a playback drive section reading first video/audio information and first playback control information from an information recording medium; a connecting section, to which an external storage device storing second video/audio information and second playback control information is electrically connected; a virtual file system section generating a virtual file system by merging the first video/audio information and the first playback control information with the second video/audio information and the second playback control information; a video/audio information output section outputting video/audio information on the basis of the virtual file system; a playback manager instructing generation and dispose of the virtual file system to the virtual file system section; a pseudo file system generator generating pseudo file system on the basis of the second video/audio information and the second playback control information; a storage section storing the pseudo file system; and a disconnection detector detecting electrical disconnection of the external storage device from the connecting section; wherein, when the disconnection detector detects that the external storage device is electrically disconnected, the playback manager issues a command to the virtual file system section so that the virtual file system section replaces the second video/audio information and the second playback control information as the virtual file system with the pseudo file system, thereby reconfiguring the virtual file system.
