<P>PROBLEM TO BE SOLVED: To stop a sending of a command to such a source apparatus when it is found that the source apparatus is non-responsive to a pass-through control, thereby enhancing a communication efficiency of the command. <P>SOLUTION: This apparatus controller 1 includes a receiver 11 for receiving an operation code sent from an operating device 3, and a processing part 14. When the receiver 11 receives the operation code, the processing part 14 decides whether or not an objective source apparatus 2 is responsive to the pass-through control of the operation code, and if it decides as non-responsive, the processing part 14 stops a sending of the command for transferring the operation code to the source apparatus 2. <P>COPYRIGHT: (C)2010,JPO&INPIT |
