Each of the electronic devices in 2, 406 and 410 and the HS 401 are connected by a communication bus 413. The connection form by the communication bus 413 includes a daisy chain connection,
Alternatively, a tree connection, or a combination thereof may be employed.

Although not shown in FIG. 4, a digital VHS, a digital video camera, a hard disk drive,
Electronic devices such as printers, scanners, and audio devices can also be connected.

As described above, a plurality (a large number) of communication buses are provided.
In the transition of the electronic environment when electronic devices are connected, first, a source and a destination of the electronic environment are determined from a plurality of electronic devices, and then the electronic environment from the source to the destination is determined. Is determined, and if the migration is possible, the electronic environment is migrated to the destination.

For example, as shown in FIG. 4, when a large number of electronic devices are connected, the TV 403 to the TV 4
An example of the transition of the electronic environment to 07 will now be described.

In this case, first, the source Roo
At m402, the chase button 303 of the remote control 105 is pressed. By this operation, the TV 403 in the Room 402
Makes an inquiry to the electronic device connected to the communication bus 413 as to whether there is an electronic device in the electronic environment transition mode. As a result of the inquiry, if there is no device that is in the transition mode of the electronic environment, the TV 403 determines that it is the source of the transition of the electronic environment, and the TV 403 enters the transition mode of the electronic environment. And electronic environment information such as volume.

Next, the Room in which the TV 407 of the transfer destination exists
After moving to 406, the chase button 303 is pressed again toward the TV 407. By this operation, Room40
6, the TV 407 inquires of the electronic device connected to the communication bus 413 whether or not there is an electronic device in the transition mode of the electronic environment. In response to this inquiry, the TV 403 responds to the TV 407 with information that it is the source of the electronic environment migration and information that inquires whether the electronic environment can be migrated. TV
407 receives this response information, and determines that it is the migration destination of the electronic environment.

The TV 407 determines whether or not the electronic environment can be shifted based on the information from the TV 403. If the electronic environment can be shifted, the TV 403 informs the TV 403 that the electronic environment can be shifted (ie, the electronic environment can be shifted). A request to transfer environmental information (inquiry about the contents of electronic environmental information) is transmitted. After receiving the information that the electronic environment can be shifted, the TV 403 starts transmitting information necessary for shifting the electronic environment. Thereby, the TV 407 receives the electronic environment information and constructs the same electronic environment as the TV 403.

It should be noted that when the electronic device at the transfer source of the electronic environment has already been determined, it is detected that the chase button 303 has been pressed next, and the above-described inquiry from the electronic device at the transfer destination (already the electronic device) The source electronic device recognizes the destination electronic device by inquiring whether there is any electronic device that is in the environment transition mode, and the source electronic device immediately sends the electronic device to the destination electronic device. The environment information is transmitted, and based on the electronic environment information, the electronic device at the migration destination determines whether or not the electronic environment can be migrated. If the electronic environment can be migrated, the electronic environment at the migration destination is sent. An electronic environment may be constructed based on the information.

According to such a procedure, even after moving to the Room 406, the user can view the TV in the same electronic environment as the Room 402 without performing the electronic environment setting such as the operation of selecting the music of the TV and adjusting the volume. it can.

Next, as shown in FIG. 4, an example of a process of shifting an electronic environment in a communication bus to which a large number of electronic devices are connected will be briefly described with reference to a flowchart of FIG.

Step 500 is called at the start of the electronic environment transfer process. The start of the electronic environment transition processing is performed by pressing the chase button 303 of the remote control 105.
This is performed by activating the electronic environment transition processing program sensed by the input / output unit 203 and stored in the ROM unit 210.

In step 501, a source and a destination electronic device of the electronic environment are determined. For this reason, first, the electronic device that has detected that the chase button 303 has been pressed, sends the electronic device connected to the communication unit 205 and the communication bus 413 to the electronic device already in the electronic environment transition mode. Ask if there are any. As a result of this inquiry, if there is no other electronic device that is in the transition mode of the electronic environment, it is determined that the electronic device is the electronic device of the migration source, and to that effect, the electronic environment information at that time, The information is stored in the storage unit 204. If there is an electronic device that is already in the transition mode of the electronic environment, the information that the electronic device that is in the transition mode is itself the transition source of the electronic environment as described above,
Inquiry information about whether the electronic environment can be migrated,
Since the electronic device is sent, the electronic device that has detected that the chase button 303 has been pressed later determines that the electronic device is the electronic device of the transfer destination.

In step 502, it is determined whether or not the electronic environment can be shifted. The electronic device that is the source of the electronic environment transfer, as inquiry information as to whether or not the electronic environment can be transferred, information such as the setting status of the device and the amount of data being handled through the communication unit 205 through the electronic environment. To the destination electronic device. The electronic device to which the electronic environment is to be transferred receives the information from the electronic device of the transfer source in the communication unit 205, compares the electronic environment conditions and the like of the transfer source with its own electronic environment conditions and the like in the CPU 203, and performs the transfer. If it is determined that the transfer is possible, the process proceeds to step 503. If it is determined that the transfer cannot be performed, the process proceeds to step 505.

In step 503, the electronic environment is shifted. The source electronic device transmits necessary setting information and data to the destination electronic device, and the destination electronic device constructs a new electronic environment based on the transmitted information. . Then, the process proceeds to step 504, and the electronic environment transition processing flow ends.

On the other hand, if it is determined in step 502 that the transfer of the electronic environment is impossible or partially determined to be impossible, the process proceeds to step 505, and the reason is displayed on the display unit 202. Proceed to step 506.

In step 506, an operation of selecting an environment item or canceling the process is performed. That is, if the electronic environment transfer process is to be stopped, the process proceeds to step 504 to end the process.
This is selected, and the process proceeds to step 503 described above.

Next, as shown in FIG. 4, an example of a case where a plurality of electronic devices are connected to a communication bus 413 and the electronic environment is transferred between the plurality of devices will be described.

For example, in the Room 402, the IRD 404
Watching TV programs with TV 403, Ro
In the case of moving to the om 106 and shifting the electronic environment in the Room 402 (the electronic environment of the IRD 404 and the TV 403), similarly, first, the source of the electronic environment is transferred between the IRD 404 and the IRD 408 and between the TV 403 and the TV 407. And the migration destination are determined, and then the electronic environment migration between the source electronic device and the destination electronic device is determined,
Finally, by establishing an electronic environment in each of the plurality of electronic devices (IRD 408 and TV 407) at the destination, it is possible to transfer the electronic environment between the plurality of devices.

Here, if the remote controller 105 communicates with each electronic device on a regular basis, each electronic device will
05 can be detected periodically. In addition, the remote control 105 can also detect the position of the remote control itself based on information from the electronic device that is performing communication.
As described above, if the remote controller 105 is configured to periodically communicate with each electronic device, the chase button 3
If the operation of pressing 03 is performed, the remote controller 105 communicates with the electronic device at the stage when the destination is reached, the destination is automatically determined, and the shift of the electronic environment is performed. Since there is no need to press the button 303 again, the transition of the electronic environment can be performed more easily. Furthermore, if the electronic environment is always set to be transferred to the destination of the remote controller, it is not necessary to determine the electronic device of the transfer source, so that the electronic environment can be transferred more easily.

As described above, in addition to the remote controller 105 performing communication, the movement of a person is detected by sensors 414, 415, and 416 shown in FIG. , The source and destination locations can be determined. If the location of the person who has moved can be determined, the electronic environment can be automatically shifted between the electronic devices. Therefore, it is not necessary to carry the remote controller 105, and the electronic environment can be shifted more easily.

It is to be noted that the sensor may be a sensor based on infrared rays, a sensor based on radio waves, a sensor based on image recognition, or a combination thereof.

Further, for example, even when the TV 103 and the TV 104 shown in FIG. 1 are not connected by the communication bus cable 106, the electronic environment information of the TV 103 is stored in the remote control 105 when the chase button 303 is pressed. Next, when the chase button 303 is pressed toward the TV 104, if the electronic environment information stored in the remote controller 105 is transmitted to the TV 104, the electronic environment of the TV 103 can be transferred to the TV 104. . Similarly, even when a large number of electronic devices are not connected to the communication bus, the electronic environment information of a plurality of transfer source electronic devices is stored in the remote control 105, and the electronic environment information is transmitted from the remote control 105 to the transfer destination electronic device. By transmitting to the electronic device, the electronic environment can be shifted.

By the way, when it is desired to shift the electronic environment of only a specific electronic device or when there are a plurality of persons, it may be better to give a clear instruction to each electronic device.
Also, if you always want to make the same transition of electronic environment,
By registering the method of shifting the electronic environment, the shift of the electronic environment can be performed more reliably and easily. Hereinafter, examples of actual screens will be shown, and these will be described.

First, an operation example of an electronic device having means for more clearly selecting and instructing a source or a destination electronic device of the electronic environment will be described.

FIG. 6 shows a source selection screen 600 for manually determining the source and destination electronic devices in the electronic environment.
This is an example. When the chase button 303 and the operation button 302 of the remote controller 105 are pressed at the same time, such a screen may appear. The left side of the screen is a screen field 601 for selecting a source electronic device of a specific electronic environment, and the right side of the screen is a screen field 602 for selecting a destination location of a specific electronic environment.

In the example shown in FIG. 6, the TV 603, which is the electronic device from which the electronic environment is transferred, is selected by using the operation buttons 302 and the like of the remote control 105. Next, in order to select a migration destination device, first, a destination location is selected. Here, the room RoomB 607, which is the destination, is selected. In FIG. 6, the RoomC 608 is displayed thin (indicated by a broken line in the drawing).
This indicates that there is no V, and the electronic environment cannot be completely transferred.

When the transfer destination of the electronic environment is designated, the selection screen 600 is switched to a selection screen 700 shown in FIG. Therefore, next, the electronic device to which the electronic environment is transferred in the RoomB is selected. Here, the TV 703 is selected from the device selection screen field 701 of the electronic environment transfer destination on the right side of the screen in FIG. Note that in FIG.
Although D704 is displayed lightly, when the environment from the TV cannot be transferred to the IRD, the display is changed in this way so as to be easily understood.

Next, an example of operation of an electronic device having means for registering information on the location of the electronic device connected to the communication bus in the home and device information related to the transition of the electronic environment will be described.

FIG. 8 is an example of the information setting screen menu 800, and the chase setting screens 600 and 70 shown in FIGS.
0 and appears when option 609 is selected. Here, addition / deletion of a place, addition / deletion of a device, and function setting are performed.

First, when the place addition / deletion item 801 in FIG. 8 is selected, a place addition / deletion setting screen 900 in FIG. 9 is displayed, and the currently registered chase target place is displayed in the left screen column 901. Is done. The right screen field 902 has a place setting menu, a new addition menu 907 for adding a new place, a delete menu 909 for deleting a place, and a name change 91 for changing the name of a place.
A menu such as the 0 menu is displayed. If you select the desired menu and make settings, the room (location) information will be updated.

The device addition / deletion menu 80 shown in FIG.
When 2 is selected, the device addition / deletion setting screen 10 shown in FIG.
00 is displayed. Here, settings such as addition and deletion of an electronic device and movement of an installation location related to the shift of the electronic environment are performed. For example, DVD is Room
If you do not want to watch other than A, left screen field 1
If the DVD 1006 in 001 is selected, and then the delete 1009 in the right screen field 1002 is selected, the DVD is deleted from the electronic environment transfer target device registration. In the case where the deleted device is added again or a new device is connected, selecting a new addition 1007 makes the device a target device. Also, if you want to change the location of the equipment,
Move 1008 is selected to set a new installation location.

When the function setting menu 803 in FIG. 8 is selected, a function setting screen 1100 in FIG. 11 is displayed. Here, a priority transfer source, a priority transfer destination, and a main body function are set. For example, Ro
In the case where the electronic environment is always transferred only to the Room B IRD, the OmA IRD selects the IRD 1105 in the device selection screen column 1101 on the left side of the screen, and then the priority transfer in the function setting screen column 1102 on the right side of the screen. Destination menu 1

Thus, the function setting screen 11 shown in FIG.
00 is a function setting (priority destination selection) screen 12 shown in FIG.
00, and on the function setting (priority transfer destination selection) screen 1200, the IRD 12
By selecting 09, the device is registered as a priority electronic environment shift device, and the environment is shifted preferentially.

The setting registration data of these connected devices may be stored in the storage unit 204 of each electronic device, and may be called from another electronic device as needed. It may be executed preferentially when pressed. Alternatively, the information may be stored in the home server 401 or the like and collectively managed.

After the transfer of the electronic environment is completed, the electronic device at the transfer source may be configured to have a device capable of turning off the power or saving.

Further, by selecting and registering only the electronic devices related to the migration of a specific electronic environment, or by registering the migration destination of the electronic environment in advance, it is possible to more easily and surely migrate the electronic environment. become able to.
