Abstract: A COMMUNICATION SYSTEM COMPRISES ITEMS OF EQUIPMENT CONNECTED VIA A BUS CAPABLE OF TRANSFERRING COMBINATIONS OF CONTROL SIGNALS AND AV SIGNALS AS PACKETS WHILE PROVIDING AN ENVIRONMENT WHICH IS THE SAME AS AN ENVIRONMENT WHERE CONNECTIONS ARE MADE USING ANALOG SIGNAL LINES. A REGISTER DECIDED BY AN ADDRESS IS TAKEN TO BE A VIRTUAL PLUG FIR EACH ITEM IF EQUIPMENT. A PLUG ENABLE FOR AN INPUT PLUG (10) IS SET TO 1 AND A SYNCHRONOUS COMMUNICATION PACKET FOR THE AV SIGNAL FROM THE CHANNEL SET BY THE CHANNEL NUMBER IS RECEIVED. A PLUG ENABLE FOR AN OUTPUT PLUG (11) IS SET TO ONE AND THE SYNCHRONOUS COMMUNICATION PACKET FOR THE INFORMATION SIGNAL IS SENT TO THE CHANNEL SET BY THE CHANNEL NUMBER AT A TRANSMISSION SPEED DESIGNATED BY THE DR (DATA RATE) AT THE BANDWIDTH EXPRESSED BY "BANDWIDTH".(FIG 1)

Abstract: There is provided a method of controlling communication for a communication system for connecting a plurality of electronic apparatuses through a communication control bus and allowing data communication between those electronic apparatuses wherein each of the electronic apparatuses performs connection control through the execution of a connection control command carried out by writing connection control information in a predetermined storage means of its own or another electronic apparatus. The electronic apparatuses which attempt to write the connection control information transmit the write instructions in a predetermined storage means. The storage means which has received the write instructions executes only the earliest write instruction and transmits responses indicating whether the execution of respective write instructions is successful or not.

Abstract: A bus management node 11 has a register for channels in use REG1 and a bus capacity register REG2. Before starting the synchronous communication, each node 12 transmits a read-out command to the register for channels in use REG1 and the register for channels in use REG1 in order to read out their contents for ascertaining the number of the un-used channel and the residual capacity. If there is any un-used channel and any residual bus capacity, the node 12 transmits write commands to these registers REG1 and REG2 so that the number of the channel to be in use and the capacity of the bus to be in use will be stored in the register for channels in use REG1 and the bus capacity register REG2. This enables bus management to be achieved easily in a system performing synchronous communication between plural nodes connected to the bus.

Abstract: An editing method in a system of connecting a plurality of equipments by a communication control bus in which isochronous communication and asynchronous communication can be present together and conducting communication between each of the equipments, in which an edition controlling equipment controls a plurality of equipments to be controlled thereby editing isochronous communication data to a recording equipment as one of said equipments to be controlled, said method comprising the following steps of: asking to the equipment to be controlled a first delay time from the instance a predetermined command is received by the equipment to be controlled to the instance the processing corresponding to the command is executed by asynchronous communication, asking to the equipment to be controlled a second delay time of a time code obtained by asynchronous communication from a time code in isochronous communication data by asynchronous communication, asking the time code by the isochronous communication to the equipment to be controlled, and obtaining a boundary position information in the unit section of the isochronous communication from the isochronous communication data, or asking to the equipment to be controlled a third time information from the top position of the unit section of the isochronous communication by the asynchronous communication, and sending a predetermined command at a predetermined timing by the asynchronous communication, based on the first and the second delay times, and the boundary position information or the third time information. There is therefore provided a method of editing isochronous communication data and an edition controlling equipment, wherein edition at a high accuracy can be conducted without reading the system data of isochronous communication in a system in which isochronous communication and asynchronous communication can be present together; edition can be conducted at a high accuracy also in a system in which the edition controlling equipment cannot recognize the boundary in the information signals; and even if there are various delay times from reception till execution of an instruction in the equipment to be controlled, edition can be conducted at a high accuracy.

Abstract: A network system wherein any device in all networks can be represented using addresses set in the individual networks without relying upon the concept of a network number is disclosed. A first network (1) includes first to third devices (A, B, C) to which the addresses of "1", "2" and "3" are allocated, respectively. A second network (2) includes first to devices (D, E, F) to which the addresses of "1", "2" and "3" are allocated, respectively. A third network (3) includes first and second devices (G and H) to which the addresses "1" and "2" are allocated, respectively. The first and second networks (1, 2) are connected to each other by way of a gateway (GW1) and the second and third networks (2 and 3) are connected to each other by way of another gateway (GW2) to build up a network system. A pass from within a network to another device in another network is represented using the addresses set in the individual networks. For example, the pass from the first device (A) in the first network (1) to the second device (H) in the third network (3) is represented as "4.4.2".

Abstract: In order to make it possible to efficiently collect data related to devices between devices connected to each other through an IEEE 1394 bus or the like, pieces of connection information which are connectable in the device are held at once as a predetermined table, and all or part of the pieces of connection information in the held table are transmitted to another device on the basis of transmission of a protocol of a predetermined format through the bus line. Otherwise, when data for designating an input unit, an output unit, and an internal function processing unit held by the device is transmitted from another device by the protocol of the predetermined format through the bus line, so that data related to the status of a connection of the input unit, output unit, and the internal function processing unit of the corresponding device is transmitted to the bus line.
