    Abstract: The present invention provides a control apparatus for controlling a plurality of recording and reproducing apparatuses (50, 60, 70, 80). The control apparatus according to the present invention comprises elapse time measuring means, responsive to an input reset signal determining an input time point, for commencing to measure time elapse with reference to the input time point, recording position information output means, responsive to an input predetermined signal, for detecting and outputting recording position information from a record medium of one of the recording and reproducing apparatuses, and control means for receiving the time elapse measured by said elapse time measuring means, determining an execution time in response to the time elapse, and executing an operation command at said execution time in response to said operation command.

    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 method and a system for setting addresses while connecting a plurality of electronic appliances, such as audiovisual appliances in series for transmitting and receiving information and control signals. The transmission and reception of the information signals is collectively controlled by a control unit. A connection-apparatus coupled to a succeeding connection-apparatus, and to an electronic appliance. The control unit determines an execution time for performing a particular operation when a predetermined time interval has elapsed.

    Abstract: Transmission of contents from a transmitting apparatus to a plurality of receiving apparatuses is performed, while putting restrictions on a communication area and the number of receiving apparatuses in conformity with a definition of DTCP. In a case of a need to distribute literary works such as movies and the music within a single home network, while preventing the transmission of the literary works to other home networks, a degree of freedom in communication is raised in a case where a communication delay time is short so that a high possibility exists that the communication delay time falls within a specific range. Conversely, in a case where the communication delay time is long so that a low possibility exists that the communication delay time falls within the specific range, the degree of freedom in communication is lowered. Thus, it is allowable to implement a system that ensures a high barrier to unauthorized content distributions, and also, does not have any remarkable restrictions on a rightful home use.

    Abstract: A data communication technique enables a reduction in the number of terminals in equipment for inputting or outputting a real time digital signal such as a digital audio signal and a music/musical instrument signal. A first converter (6) and a second converter (7) are provided with a function of mutual conversion between a signal format of a digital audio interface and a signal format of IEEE-1394. For example, it is possible to transmit a signal of a digital audio interface outputted from a first CD player (1) to the first converter (6), to convert the signal there into a packet of IEEE-1394 isochronous transmission format and transmit it to the second converter (7), and to return the packet to the digital audio interface and record a digital audio signal in an MD recorder (3). When a converter having a function of mutual conversion between the MIDI signal format and the IEEE-1394 signal format is provided, it is also possible to perform bidirectional data communication among a plurality of MIDI musical instruments.
