PROBLEM TO BE SOLVED: To safely and surely transfer stream data tentatively recorded by a recorder to a medium of other recorder in stream data transmission on a bus for which copyright is protected. SOLUTION: When a device other than a move destination is connected, move start is inhibited. When the other device is connected during move execution, move is tentatively intercepted, and in a state where only the move destination is connected, move is resumed. Furthermore, contents to be moved are tentatively accumulated from the outside into an unaccessible different memory in advance prior to starting move. When move is made successful, the contents accumulated in the memory are deleted. When move is failed, only analog playback can be performed from the memory. COPYRIGHT: (C)2009,JPO&INPIT
