PROBLEM TO BE SOLVED: To allow a system parameter to be changed even for other than a DVD player. SOLUTION: Encoded data outputted from a DVD player 1 are outputted to the decoders 4-1 to 4-3 of digital television receivers 3-1 to 3-3 via an AV bus 5, to be decoded. If an instruction for changing a system parameter is inputted to one of the decoders 4-1 to 4-3, a command corresponding to the change is supplied to the DVD player 1 via the AV bus 5. The DVD player 1 changes the system parameter corresponding to this command, and outputs the changed system parameter to each of the decoders 4-1 to 4-3 via the AV bus 5.
