In a FAT file system, a moving image file management table is formed so as to specify a boundary or limit of each unit of encoding and to utilize the moving image file management table for reproducing moving image files. In this case, the first inductor is coupled to the second inductor in at least one of the at least two thin-film layers when the bandpass filter is energized. Each node stores the COF value and uses the COF value to generate subsequent ciphering keys that are employed to encrypt data transmitted between the nodes. In response to receiving a mobile internet protocol access accept message at the mobile network internet node transferred from the authentication node where the mobile internet protocol access accept message comprises the mobile network internet node key, the mobile network internet node assigns the mobile internet protocol address to the mobile station associated with the user identifier. The method further includes the steps of providing a memory address pointer, wherein the memory address pointer indicates a next available memory address in the memory address pool, and reading available memory addresses from the memory address pool using a last in first out operation.
