Abstract
The encoded data outputted from a DVD player 1 are outputted to and decoded in the decoders 4-1 to 4-3 of digital television receivers 3-1 to 3-3 through an AV bus 5 comprising the IEEE 1394. When a command for changing a system parameter is inputted to any one of the decoders 4-1 to 4-3, the command corresponding to the change is supplied to the DVD player 1 through the AV bus 5. The DVD player 1 changes the system parameter in response to the command and outputs the system parameter to the respective decoders 4-1 to 4-3 through the AV bus 5. Thereby, the system parameter is changed not only in the DVD player but also in other components.
