A communication method for facilitating alteration of a transmission line in the case where the target device establishes a connection on the bus and thereby securing a transmission line in order to transmit stream data in a network of the IEEE 1394 scheme or the like. Stream data outputted from an output device connected to a predetermined network is received by an input device. When the output device or a different device has sent an order for setting so that output data of the output device may be inputted to a data input section of the input device, the input device conducts input setting based on the order. In addition, when the device which sent the order has sent an order to cancel the input setting, the input device conducts processing of canceling the input setting.
