PURPOSE: A duplication method for transmission device's duplicated device's program is disclosed to simplify the development of programs by duplicating SWAP and other unique functions of duplicated transmission device. CONSTITUTION: A duplication method for transmission device's duplicated device's program is composed of execution, examination, and repetition. If SWAP is requested during the execution of first program, CPU's execution rights are given to second program and step (500) is processed. In step (500), CPU executes first device's unique functions and proceeds to step (502), which checks if SWAP event has been executed. If occurred, request for second device's SWAP(504), move to first program's step (420) and shut down the first device. If SWAP event has not occurred, check if second device's SINK message can be provided(506). If it can be provided, provide SINK message(508) and CPU checks for parameter renewal request(510). If it cannot be provided, CPU checks for parameter renewal request. If there has been a parameter renewal request, request for second device's first program renewal, return to step (500) and continue to execute the device's unique functions.
