    Abstract: A communication method and apparatus simplifying received data processing and eliminating use of high-speed processing equipment. In the first communication apparatus according to this invention, received data of different types are stored in respective buffers, so that the received data need not be read out immediately but may be read only when required, thereby eliminating use of high-speed processing apparatus. Additionally, received data need not be sorted after being read from the buffers, thereby simplifying the processing of the system. In the first communication method according to this invention, if a command and a request are the same in operand, the operand of the request is not sent, thereby reducing an amount of data to be transmitted. In the second communication method according to this invention, communication is always performed in the unlocked state, so that no unlocking instruction is required to change states from locked to unlocked, thereby further reducing an amount of data to be transmitted.

    Abstract translation: 通信方法和装置简化了接收到的数据处理并消除了高速处理设备的使用。 在根据本发明的第一通信装置中,不同类型的接收数据被存储在相应的缓冲器中,使得接收的数据不需要立即读出,而是可以在需要时被读取,从而消除高速处理装置的使用。 此外,在从缓冲器读取之后,不需要对接收到的数据进行排序,从而简化了系统的处理。 在根据本发明的第一通信方法中,如果命令和请求在操作数中相同,则不发送请求的操作数,从而减少要发送的数据量。 在根据本发明的第二通信方法中,始终在解锁状态执行通信,使得不需要解锁指令来将状态从锁定状态改变为解锁状态,从而进一步减少要发送的数据量。

    Abstract: There is disclosed a communication system using a bi-directional bus, which includes a plurality of devices (e.g., TV image receiver or video tape recorder, etc.) connected to each other. Each device comprises a transmit signal formation unit adapted to form a transmit signal having a frame structure consisting of an address field for specifying addresses of devices between which communication is carried out, a control field for specifying a data communication command indicating communication of data or a control command communication command indicating communication of control command, whereby, in transmitting data, the device specifies the content of the control field of the leading frame as the data communication command to form the transmit signal; a bus output unit for outputting the transmit signal formed by the transmit signal formation unit to the bi-directional bus; a bus input unit adapted to receive the bi-directional bus; and a control unit for detecting on the basis of the content of the control field of the leading frame of the transmit signal received by the bus input unit whether current communication is communication of data or communication of control command, whereby when communication of data is detected, the control unit recognizes that the content of the data field of this frame is specified as data to carry out a control to receive data. In addition, there are also disclosed a transmitting method, a receiving method and a communication method which can be applied to such a bi-directional bus system.

    Abstract: A remote control method for an audio/visual system which can perform protection during execution of a system feature and is convenient in use is disclosed. The remote control method is applied to an audio/visual system wherein each of a plurality of audio/visual equipments includes a microcomputer for controlling operation of the audio/visual equipment. The microcomputers of the audio/visual equipments are connected to each other by way of a bus system. One of the audio/visual equipments is set as an audio/visual center equipment. The audio/visual center equipment controls the entire system in a concentrated manner. The audio/visual center equipment receives remote control signals in a concentrated manner without causing remote controller receiver sections of the audio/visual equipments other than the audio/visual center equipment to function and transfers necessary commands to the audio/visual equipments. Also novel system feature starting method and controlling method for an audio/visual system of the type mentioned are disclosed.

    Abstract: A method of controlling signal lines among a number of audio/video units in a system where a central unit including a selector and the other audio/video units are mutually connected via a single control bus and also via audio/video signal cables includes the steps of enabling the central unit to manage identification numbers of the audio/video units on the control bus and also connection data among the audio/video units, classifying the audio/video units in accordance with the respective categories, connecting the signal line between one of the audio/video units and another one of the units, enabling one audio/video units to designate by category the other audio/video unit to be connected and, after such designation, enabling the central unit to select the specific audio/video unit that satisfies the requirement, out of all of the audio/video units of the designated category, and then switching the selector of the central unit thereby connecting the desired signal line between the relevant audio/video units.

    Abstract: An audio visual control apparatus for communication between a master device and a slave device comprises a master AV center, at least one slave device, a digital control bus line and a transmitter. The master AV center has at least a display device and a communication processor. A minimum of one slave device is provided, having a communication processor connected to the master AV center via the digital control bus line between the two communication processors. The transmitter transmits one command and/or data in a single packet from the master AV center to the slave device and vice versa through the digital control bus line.
