Abstract: A sink apparatus receives stream data outputted from a source apparatus connected to a predetermined network. When the source apparatus or an other apparatus connected to the network transmits a command to configure a data input section of the sink apparatus to input data outputted from the source apparatus, data are prepared to indicate that a configuration of the data input section is at least temporarily disabled as a response from the sink apparatus. When the apparatus that transmitted the command receives the data indicating that the configuration is at least temporarily disabled corresponding processing may be executed. When stream data are transmitted through a network it can be easily determined by an other apparatus on the network whether the sink apparatus is ready to input data.

Abstract: When information is transmitted among a plurality of devices connected through a network, an information opening data storage section for opening predetermined information is set to devices connected through the network, the information opening data storage section is formed in a descriptor format having a predetermined hierarchical structure, predetermined information is stored in a board 910 set in the descriptor format, the position at which the predetermined board 900 is stored is directly instructed by the highest-order descriptor 900 having the hierarchical structure, and information concerning a predetermined information is stored in information areas 921, 922, 931, 932 instructed when the hierarchical structure is retrieved from the highest-order descriptor 900.

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.

Abstract: A DTV operating screen is displayed on the CRT display screen of a DTV which is the controlling apparatus of a network. In the event that the user selects the DVHS from the buttons displayed on the DTV operating screen, data corresponding to the DVHS operation screen is input to the DTV, and a DVHS operation screen is displayed on the CRT display screen 61. The user operation executed regarding the DVHS operation screen are notified from the DTV to the DVHS, so the DTV can execute control corresponding to the operations of the user, without transmitting commands for directly controlling the DVHS.
