Abstract: A digital television (DTV) operating screen is displayed on the cathode ray tube (CRT) display screen of a DTV which is the controlling apparatus of a network. In the event that the user selects a digital video home system (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 instructions executed regarding the DVHS operation screen are notified from the digital television 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.

Abstract: Any of the AV devices or the users of a network system to which the present invention is applied can input detailed information on a recording reservation and provide the remaining AV devices and the users with the detailed information on the recording reservations that the AV device or the user has and it is possible to realize a means to be used by any of the AV devices or the users to provide the remaining AV devices and the users with the detailed information on the recording reservations that the AV device or the user has. Such a system can effectively avoid occurrence of so-called double booking and is easy to use for the users. In a specific processing operation, raw_text_information_block containing a raw text showing details of a reservation and character_code_information_block and language_code_information_block showing the coding of the raw text are described in a Resource Schedule Entry of an RSB.

Abstract: 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.
