摘要:
An information processing apparatus is connected to another information processing apparatus via a network and has at least one sub-unit for executing a predetermined function. A reservation is made for causing a tuner sub-unit of an IRD to receive a predetermined channel broadcast at a predetermined time and to record it on a VCR sub-unit of a DVCR via an IEEE-1394 serial data bus. Then, a controller of the IRD writes reservation information into a Resource Schedule Board (RSB) built into a Bulletin Board Subunit (BBS) of the IRD and also writes reservation information of the VCR sub-unit into a RSB built into a BBS of the DVCR. With this arrangement, double-booking is prevented.

In order to set a user information such as a nickname, memo or the like easily in an electronic appliance, text data or graphic data about the appliance entered on the basis of a specified manipulation or command is written by using a part of the descriptor which can be read out by the command conforming to a specified protocol from other appliance connected mutually through a bus, and when displaying about the appliance, the nickname, memo or the like by the text data or graphic data written in the descriptor is displayed.

A controller of an IRD generates a provisional ID for uniquely identifying an Event within the unit. Then, an Event within the unit is read from a Resource Schedule Board (RSB), and a record ID (Event ID) of the Event is extracted. A provisional ID, which is different from the registered record IDs within the related unit, is searched for. The searched provisional ID is set to be the record ID and is combined with a global unique ID (GUID) of the unit, thereby generating an Object ID. As a result, the Object ID for uniquely identifying the Event within a bus is speedily determined.

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.
摘要:
Communication method and apparatus for allowing restriction-free transmission of various kinds of information, such as control information, among devices constituting, for example, an IEEE 1394 network. At least one of the network-linked devices is provided with a storage region to/from which data can be written/read out by any other device on the network upon transmission of a predetermined command, so that data can be transmitted throughout the network by using the storage region.

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.

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.
摘要:
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.
