1. An information device system comprising:
- at least two information devices connected via a bus or a network, said information devices having ID numbers automatically assigned subsequently to being connected to said bus or network, wherein each information device identifies the other information device using the ID number of the other information device, wherein each information device comprises;
storage means for storing device name data indicating a name of said information device to provide information used for distinguishing an identification of said information device from the other information device, and another storage means for storing function data including instruction data used for enabling said information device to be controlled by the other information device, wherein said information device sends to the other information device said function data including information data in response to a request from the other information device and receives from the other information device information which is generated by the other information device based on said function data received so that said information device is controlled by the other information device, wherein at least one of said information devices further comprises;
first storage means for storing device name data received from the other information device, and second storage means for storing function data sent from said the other information device, wherein said one information device controls the other information device such that said one information device requests one or more other information devices in said system to send device name data and stores the received device name data in said first storage means, requests a subject information device to be controlled among the other information devices in said system to send function data and stores said function data sent from said subject information device in said second storage means, generates control information based on said function data stored in said second storage means for controlling said subject information device and sends the generated control information to control said subject information device.

Abstract
A device including a self-information memory which stores function data for other devices to operate the device and device name data. Upon receiving a request from another device for the device name or function data, the device sends the data stored in the self-information memory. When function data is thereafter received, the device executes a function indicated by the data. When plural devices are connected to each other via a network, device acting as a master device, includes a connected device memory which stores device name data of all connected device and a communication pair memory which stores function data of the communication partner.

4. An information device which configures an information device system which includes a plurality of said information device including said information device and at least another information device connected to said information device via a bus or a network, said information device having ID number automatically assigned subsequently to being connected to said bus or network, wherein said information device identifies the other information device using the ID number of the other information device, said information device comprising:
-
storage means for storing device name data including a name of said information device to provide information used for distinguishing an identification of said information device from the other information device;
another storage means for storing function data including instruction data for enabling said information device to be controlled by the other information device;
first storage means for storing device name data received from another information device; and
second storage means for storing function data received from a subject information device to be controlled by said information device, wherein when said information device is to be controlled by said another information device, said information device sends to said another information device said function data including instruction data in response to a request from said another information device and receives from said another information device information which is generated by said another information device based on said function data received so that said information device is controlled by said another information device, wherein when said information device is to control a certain information device, said information device requests said at least another information device to send device name data and stores the received device name data in said first storage means, request said certain information device to be controlled among said at least said another information devices to send function data, receives said function data from said certain information device data and stores the received function data in said second storage means, generates control information based on said function data stored in said second storage means for controlling said certain information and sends the generated control information to said certain information device to control said certain information device. - View Dependent Claims (5, 6)

7. A method for controlling an information device system having at least two information devices connected via a bus or a network, each information device having device name data indicating a name of said information device to provide information used for distinguishing an identification of said information device from the other information device and function data including instruction data used for enabling said information device to be controlled by the other information device, said information devices having ID numbers automatically assigned subsequently to be connected to said bus or network, wherein each of said information device identifies the other information device using the ID number of the other information device, said method comprising the steps of:
-
requesting a second information device to send deice name data including a name of said second information device which said second information device has to a first information device when said second information device is to be controlled;
storing said device name data sent from said second information device to said first information device, when said second information device is to be controlled, requesting said second information device to send function data including instruction data which said second information device has for enabling said second information device to be controlled;
receiving said function data sent from said second information device an storing the received function data in storage means of said first information device;
generating control information based on said function data received by said first information device for controlling said second information device and sending the generated control information to said second information device to control said second information device, when said first information device is to be controlled by said second information device, receiving a request for device name data from said second information device and sending device name data from said second information device and sending device name data from said first information device to said second information device;
receiving a request for function data from said second information device and sending from said first information device function data including instruction data for enabling said first information device to be controlled by other information devices to said second information device; and
