Abstract

The problem is to facilitate alteration of a transmission line in the case where the target device establishes a connection on the bus and thereby secures 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 1 connected to a predetermined network is received by an input device 2. When the output device or a different device has sent an order for setting so that output data of the output device 1 may be inputted to a data input section 2b of the input device 2, the input device 2 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 2 conducts processing of canceling the input setting.

Dependent claims

A communication method for an input device to receive streaming data output from an output device that is connected to an IEEE 1394 network, the method comprising:

performing input setting by the input device when an order for setting transmitted from the output device or another device is received at the input device, the input setting including an order to specify an input plug of the input device and a plug of an internal function block of the input device, wherein the input setting is performed based on said order for setting so that the data output from the output device is input to a data input section of the input device;
and
canceling said input setting by the input device when said output device or another device that transmitted the order for setting transmits an order to cancel the input setting.
