Description

  The present invention relates to a method of coordinating devices (setting, control, and information provision) based on a user's use history obtained from a plurality of devices connected to each other via a network.

As a conventional system that controls each device to a recommended operation state based on the usage history of the device, for example, a usage history of a plurality of home appliances is stored in a bidirectional remote controller, and the stored usage history is transmitted via a network. To the server with the hobby / preference analysis function, and from the server, as a result of analyzing the usage history, "recommended information" that matches the user's preference (for example, "recommended program" if the operation target is a TV or video) Is transmitted to a two-way remote controller, and the user selects “recommended information” to control the device (for example, see Patent Document 1). According to this system, when the user selects a video with the bidirectional remote controller as an operation target, a “recommended program” is displayed on the remote controller, and the scheduled recording control of the program can be performed. When a microwave oven is selected, a "recommended recipe" is displayed on the remote controller, and a control command for the microwave oven can be transferred from the remote controller.

The user IF 1001 also includes a remote controller with a tablet, a software keyboard mounted on a PDA, and the like.

The operation of the first embodiment configured as described above will be described with reference to the timing chart of FIG. 3 and the flowcharts of FIGS. In order to explain the operation of the present embodiment more clearly, a description will be given of an example of a cooperative operation between the DTV, the PC, and the MD component.
As shown in FIG. 3, the operation of the present embodiment is as follows.
Processing procedure 1: Notify another device of a user operation event,
Processing procedure 2: receiving an operation event from another device and returning a related operation log,
Processing procedure 3: The user analyzes the related operation log received from another device, selects and processes the presented result, and transmits the cooperative operation content to the cooperating device.
Processing procedure 4: It consists of four processing procedures of receiving and executing the contents of the cooperative operation. Hereinafter, the details will be described with reference to the flowcharts of FIGS.

First, processing procedure 1 will be described with reference to the flowchart in FIG. Here, the operation of the DTV in FIG. 3 will be described as an example.
Step 11a is an operation input receiving step. The device operation detection unit 101 receives an operation from a user. If there is an input, go to step 11b. If not, the device waits for an operation input. Here, it is assumed that the power of the DTV is turned off.

  Step 11b is an operation log accumulation step. The operation log accumulation management unit 102 accumulates the operations received in step 11a in a predetermined format. FIG. 7 is an example of a descriptor used for storing operation logs. For example, a combination of a date and time identifier and at least one of a device identifier, an operation identifier, a content identifier, an application identifier, a service identifier, and a user identifier is used.

Step 11c is a current operation log transmission step. The current operation log transmission unit 103 transmits a log relating to the current operation to another device. FIG. 8 shows an example of a log transmitted when the power of the DTV is turned off (PowerOff).
Step 11d is a step of checking the power of the device. Here, it is determined whether the power of the device is on (On) or off (Off). If it is off, the step ends. If it is on, the process returns to step 11a and waits for a user operation input.

Next, processing procedure 2 will be described with reference to the flowchart in FIG. Here, the operation of the PC and the MD component that receive the current operation log from the DTV will be described as an example.
Step 12a is a step of receiving a current operation log from another device. The current operation log receiving unit 104 receives a current operation log from another device. If an operation log is received, the process proceeds to step 12b. If not, it waits for the current operation log from another device. In this step, the PC and the MD component each receive the current operation log from the DTV.

  Step 12b is a step of searching the operation log with a predetermined attribute. The related operation log extraction unit 105 extracts the current operation log of the other device received in step 12a from the operation log accumulated in the operation log accumulation management unit 102 (here, the operation log accumulated in the PC or the MD component itself). Extract operation logs related to. Here, the predetermined attribute indicating the relevancy will be described using “date and time” described below the date and time identifier as an example. For example, on a date and time when an operation input to the DTV is performed, that is, during a predetermined period (for example, the past one week in the time zone from 21:00 to 22:00) before and after the time when the operation log received from the DTV is accumulated. Of the past operation log stored in the operation log storage management unit 102 of FIG. FIG. 9 shows an example of the searched related operation log. Similarly, FIG. 10 is an example of a related operation log searched for the MD component.

Step 12c is a step of confirming whether there is a related operation log. The related operation log extraction unit 105 detects the presence or absence of a related operation log from the result of the search in step 12b. If there is a related operation log, the process returns to step 12d; otherwise, the process returns to step 12a to wait for a current operation log from another device.
Step 12d is a step of creating a transmission message. The related operation log extracting unit 105 creates a message for transmitting the related operation log to the device that has received the current operation log. FIGS. 11 and 12 show examples of messages transmitted from the PC and MD component to the DTV, respectively.

Step 12e is a step of transmitting a related operation log. The related operation log transmitting unit 106 returns the message created in step 12d to the source of the current operation log. Here, the messages shown in FIGS. 11 and 12 are transmitted to the DTV from the PC and the MD component, respectively.
Step 12f is a step of checking the power of the device. Here, it is determined whether the power of the device is on or off. If it is off, the step ends. If it is on, the process returns to step 12a and waits for a current operation log from another device.

Next, processing procedure 3 will be described with reference to the flowchart in FIG. Here, the operation of the DTV that receives the related operation logs from the PC and the MD component will be described as an example.
Step 13a is a step of receiving a related operation log from another device. The related operation log receiving unit 107 receives a related operation log from another device for a predetermined period after the transmission of the current operation log, in synchronization with the transmission of the current operation log by the current operation log transmitting unit 103. If the related operation log is received within a predetermined period, the process proceeds to step 13b. If not, it waits for a synchronization signal from the current operation log transmission unit 103. In this step, the DTV receives the relevant operation logs from the PC and MD component.

Step 13b is a step of calculating the number of related operation logs. The related operation log interpretation unit 108 counts the number of related operation logs received in step 13a for each device, and ranks the devices according to the operation frequency.
Step 13c is a step of presenting the related operation log to the user. The related operation log presenting unit 109 presents the received related operation log to the user via the user IF 1001 in accordance with the operation frequency order of the devices determined in step 13b. FIG. 13 is an example of a related operation log presented to the user. This user has started the PC on and after 21:53 on weekdays, and operates the MD component on Saturday and Sunday.

Step 13d is a step of confirming whether there is an operation log suitable for the situation of the user. The user checks whether there is an operation log suitable for his / her current situation in the related operation logs presented in step 13c. That is, it is checked whether there is an operation that he or she wants to perform. If there is, go to step 13e. If not, end this procedure.
Step 13e is a step of selecting a related operation log. If there is an operation that the user intends to perform in the related operation log presented in step 13c, the user selects the related operation log using the user IF 1001. Here, since the present day is a weekday, it is assumed that the user has selected the boot of the PC and the activation of the mailer.

Step 13f is a step of generating a cooperative operation content. The cooperative operation content determination unit 110 generates a message of the cooperative operation content to the device requesting the cooperative operation from the related operation log selected in step 13e. For example, a message transmitted from the DTV to the PC as shown in FIG. 14 is generated. The content of the cooperative operation here is to boot the PC and start the mailer.
Step 13g is a step of transmitting the contents of the cooperative operation. The cooperative operation content transmitting unit 111 transmits the cooperative operation content created in step 13f to the corresponding device.

  Finally, processing procedure 4 will be described. Here, the operation when the PC receives the cooperation operation content message from the DTV will be described as an example. The cooperative operation content receiving unit 112 receives a cooperative operation content message from the partner device that has transmitted the related operation log. The received message is passed to the device control unit and executed. In the example of FIG. 14, after the PC is booted, the mailer is started.

  Note that, in steps 13c to 13e of the present embodiment, the operation in which the related operation log is presented to the user and the user selects the related operation log has been described. However, the user does not necessarily need to intervene. In the present invention as shown in FIG. 31, the related operation log determined in step 13b by the operation frequency is automatically transmitted to the cooperative operation content determination unit 110 by the device based on the operation frequency and the similarity of the day of the week and time. May be selected and transmitted to another device for control.

As described above, according to the first embodiment, as described in the processing procedures 1 to 4, the operation logs managed in a distributed manner for a plurality of devices are mutually related each time an operation event for the device occurs, and the related operation logs are mutually exchanged. By communicating, a related operation between devices is discovered and presented to the user, so that cooperative control of a plurality of devices can be easily realized.
Specifically, by extracting the relevance of the operation from the operation histories of a plurality of devices and using the operation log for cooperative control, after the user watches the 21:00 drama on the DTV on a weekday, the PC must be started. Since I sent an e-mail to a friend, when the DTV was turned off after the drama at 21:00, the device was linked to this, and the PC was started and a mailer was started. realizable.

(Second embodiment)
In the second embodiment, when the related operation log is presented to the user, the logs are grouped according to the appearance frequency of the attribute value and presented to the user. This makes it easier to determine the content.

Hereinafter, the operation of the second embodiment will be described with reference to the flowchart of FIG. However, among the four processing procedures constituting the operation of the first embodiment, only the processing procedure 3 is different, so only that part will be described using the flowchart of FIG.
Step 2a is a step of receiving a related operation log from another device. The related operation log receiving unit 107 receives a related operation log from another device for a predetermined period after the transmission of the current operation log, in synchronization with the transmission of the current operation log by the current operation log transmitting unit 103. If the related operation log is received within a predetermined period, the process proceeds to step 2b. If not, it waits for a synchronization signal from the current operation log transmission unit 103.

Step 2b is a step of calculating the appearance frequency of the attribute value. The related operation log interpretation unit 108 counts the appearance frequency of each attribute value for each device and each descriptor.
Step 2c is a step of grouping operation logs based on the appearance frequency of attribute values. The related operation log interpreting unit 108 ranks the attributes according to the appearance frequency, and groups them as shown in FIG. 16, for example. In the example of FIG. 16, the operation logs of the PC are grouped by attributes such as boot (starting up the PC) and activate (starting up the application). The numerical value described to the right of the attribute value is the frequency of occurrence of the attribute value. In this example, the user has started the application 20 times in the past week, the breakdown being 10 mailers, 5 browsers, 3 editors, and 2 image viewers.

Step 2d is a step of presenting the grouped related operation logs to the user. The related operation log presenting unit 109 presents the related operation logs grouped in step 2c to the user via the user IF 1001.
Step 2e is a step of confirming whether there is an operation log suitable for the situation of the user. The user checks whether there is an operation log suitable for his / her current situation among the grouped related operation logs presented in step 2d. That is, it is checked whether there is an operation that he or she wants to perform. If so, go to step 2f. If not, end this procedure.

  Step 2f is a step of selecting a related operation log. If there is an operation that the user intends to perform in the grouped related operation logs presented in step 2d, the user selects the related operation log by operating the cursor of the user IF 1001 or the like. For example, as shown by white circles (not selected) and black circles (selected) in FIG. 16, the selection of the related operation log can be realized by an interface such as a check box.

  Step 2g is a step of selecting an attribute value of the related operation log. If there is an attribute value that the user intends to perform in the grouped related operation logs presented in step 2d, the user selects the attribute value by operating the cursor of the user IF 1001 or the like. For example, in FIG. 16, the application identifiers are grouped for each attribute value, but the grouped attribute values are displayed in the order of frequency of occurrence as in a pull-down menu, so that the user in the past can change the current time zone in the past. Application can be easily selected. In the example of FIG. 16, a mailer (Mailer-xxx) and an editor (Editor-xxx) are selected, as indicated by thick lines.

Step 2h is a step of generating cooperative operation contents. The cooperative operation content determining unit 110 generates a message of the cooperative operation content to the device requesting the cooperative operation from the related operation log and the attribute value selected in steps 2f and 2g.
Step 2i is a step of transmitting the contents of the cooperative operation. The cooperative operation content transmitting unit 111 transmits the cooperative operation content created in step 2h to the corresponding device. Here, the boot of the PC and the activation of the mailer and the editor are transmitted from the DTV to the PC as the contents of the cooperative operation.

As described above, according to the second embodiment, when presenting the related operation log to the user, the log is grouped according to the appearance frequency of the attribute value and presented to the user, so that the user can easily obtain the attribute. Since the value can be specified, it is easy to determine the content of the cooperative operation.
Note that, in steps 2d to 2g of the present embodiment, the operation in which the grouped related operation logs are presented to the user and the user selects the related operation log and its attribute has been described, but the user is necessarily involved. There is no necessity. For example, a device may automatically select a related operation log and its attribute based on the operation frequency calculated in step 2c, and transmit the related operation log to another device for control.

(Third embodiment)
The third embodiment is designed to allow the user to freely change the attribute value of the related operation log presented to the user collectively for each device, and the user can change the attribute value of the presented related operation log. You can freely edit and describe the contents of the cooperative operation. Hereinafter, the operation of the third embodiment will be described with reference to the flowchart of FIG. However, among steps 3a to 3j in FIG. 17, only step 3h, which is a difference from the flowchart in FIG. 15 representing the operation of the second embodiment, will be described.

  Step 3h is an input step of the attribute value. The user inputs the attribute value through the user IF 1001 if any of the related operation logs presented in step 3d can be used as the contents of the cooperative operation by changing and inputting the attribute value. FIG. 18 is an example in which the user selects a log and additionally inputs an attribute value of <ApplicationID>, considering that the user wants to start Draw-soft-xxx which has not been operated in the relevant time zone until now. . As a result, the content of the cooperative operation shown in the lower part of FIG. 18 is generated and transmitted to the PC as the cooperative device.

As described above, according to the third embodiment, the user can freely change the attribute value of the related operation log presented to the user, so that the device cooperation can be freely set on the spot.
The user may additionally input an attribute value by (1) directly specifying the attribute value by the user, or (2) the current operation log receiving unit 104 or the related operation log receiving unit 107 The received operation log is accumulated, and the attribute value included in the accumulated operation log is presented to the user by the related operation log presenting unit 109 or the cooperative operation content determining unit 110, and the attribute value selected by the user is additionally input. It may be a method.

(Fourth embodiment)
The fourth embodiment is designed to allow a user to easily create a cooperative operation content by combining a plurality of attribute values. The user can select an attribute from a pull-down menu created from a related operation log. By simply selecting the attribute value, the content of the cooperative operation can be easily created. Hereinafter, the operation of the fourth embodiment will be described with reference to the flowchart of FIG. However, among steps 4a to 4h in FIG. 19, only steps 4e to 4g which are different from the flowchart in FIG. 15 showing the operation of the second embodiment will be described.

  Step 4e is a step of selecting an attribute (operation log descriptor). The user selects an attribute by a cursor operation of the user IF 1001 or the like in <new cooperation operation content: initial state> illustrated in FIG. For example, in FIG. 20, when the attribute <DeviceID> is selected, “PC.xxx-net”, “HDD.xxx-net”, and “MD.xxx-net” are displayed as pull-down menus. These displays are made by referring to the attribute value of the attribute <DeviceID> of the related operation log transmitted from another device.

Step 4f is a step of selecting an attribute value. The user selects the attribute value displayed in step 4e by operating the cursor of the user IF 1001 or the like. For example, in FIG. 20, “PC.xxx-net” is selected.
Step 4g is a step of determining the end of the creation of the cooperative operation content. The user repeats steps 4e and 4f until there are no more attributes and attribute values to be specified. If the user indicates the end of the cooperative operation by the user IF 1001 (for example, presses the end button or clicks the end GUI), the created cooperative operation is transmitted to the cooperating device in step 4h. In the example of FIG. 20, a message for transmitting the content (B-xxx.mp2) recorded on the hard disk recorder (HDD.xxx-net) is sent to “ppp.co.jp” who has sent the mail. Created.

As described above, according to the fourth embodiment, a user can easily create a cooperative operation content by simply selecting an attribute value from a pull-down menu created from an associated operation log for an arbitrary attribute. Can be.
As a method of presenting a list of selectable attribute values to the user, (1) a method of displaying a list of a plurality of attribute values stored in advance by the related operation log presenting unit 109 may be used. (2) The operation logs received by the current operation log receiving unit 104 and the related operation log receiving unit 107 are accumulated, and the attribute value included in the accumulated operation logs is listed, and the related operation log presenting unit 109 is used by the user. May be presented.

(Fifth embodiment)
In the fifth embodiment, consideration is given so that the contents of the cooperative operation selected by the user in the past can be used for the current operation log. FIG. 21 shows a configuration diagram of the fifth embodiment. The difference from the first embodiment shown in FIG. 2 is that a cooperation operation content accumulation management unit 201 for storing the current operation log and the cooperation operation content determined by the user in association with each other is added.

The operation of the fifth embodiment configured as described above will be described with reference to the flowchart of FIG. However, only steps 5a to 5c that are different from the flowchart of FIG. 6 which is the operation of the first embodiment will be described.
Step 5a is a step of confirming the contents of the past cooperation operation. The cooperation operation content accumulation management unit 201 extracts the cooperation operation content related to the current operation log from the cooperation operation content accumulation management unit 201 in synchronization with the transmission of the current operation log by the current operation log transmission unit 103. The extraction can be performed by (partially) matching the attribute values of the operation log descriptor. If there is a related cooperation operation content, go to step 5b. If not, the process waits for a related operation log from another device in step 13a.

Step 5b is a step of presenting the related past operation contents to the user. The related operation log presenting unit 109 presents the past cooperation operation contents related to the current operation log extracted by the cooperation operation content accumulation management unit 201 to the user as an operation log as shown in FIG. Then, the process proceeds to a related operation log selecting step 13d by the user.
Step 5c is a step of accumulating the cooperative operation content and the current operation log. The cooperation operation contents accumulation management unit 201 accumulates the related operation contents selected and generated in steps 13d to 13f in association with the current operation log. After the accumulation, the content of the cooperative operation is transmitted to the cooperative device in step 13g.

As described above, according to the fifth embodiment, the current operation log and the cooperative operation content determined by the user are stored in association with each other, so that the user can Since the selected cooperation operation content can be easily selected, device cooperation can be realized more easily and reliably.
Needless to say, by storing the number of times the user has selected the cooperative operation content in the cooperative operation content storage management unit 201, the cooperative operation content can be ordered according to the number of selections and presented to the user in an easy-to-understand manner.

  In addition, the user does not necessarily need to intervene in selecting the content of the cooperative operation. For example, the device may automatically select the content based on the number of selections in the past or the like and transmit the selected device to another device for control. .

(Sixth embodiment)
The sixth embodiment is designed to more easily specify the cooperative operation content by predicting the user's device operation subsequent to the current operation log and presenting the cooperative operation content. FIG. 23 shows a configuration diagram of the sixth embodiment. The difference from the fifth embodiment shown in FIG. 21 is that the related operation log received from another device and / or the cooperative operation content and the current operation log accumulated in the cooperative operation content accumulation management unit 201 are as follows. That is, a cooperative operation content prediction unit 301 for predicting the next cooperative operation content of the user is added.

The operation of the sixth embodiment configured as described above will be described with reference to the flowchart of FIG. However, among steps 6a to 6d in FIG. 24, only steps 6a to 6c, which are different from the flowchart in FIG. 22, which is the operation of the fifth embodiment, will be described.
Step 6a is a step of grouping related operation logs. The cooperative operation content predicting unit 301 groups the cooperative operation contents stored in the cooperative operation content storage management unit 201 by a combination of predetermined attributes. For example, grouping is performed based on a combination of attribute values included in the device identifier <DeviceID>, the device cooperation identifier <DeviceFrom><DeviceTo>, and the content identifier <ContentID>. In the example of FIG. 25A, the attribute value of <ContentID> is common to “A-xxxxxx”, and the attribute value of <DeviceID> and <DeviceFrom> is “HDD.xxx-net”. Content is grouped.

Step 6b is a step of specifying a group related to the current operation log. The cooperative operation content prediction unit 301 specifies grouped cooperative operation contents having common attribute values for <DeviceID> and <Command> of the current operation log. If there is a group having a common attribute value, the process proceeds to step 6c. If not, the process proceeds to step 13d.
Step 6c is a step of predicting and presenting the user operation behavior. For example, the cooperative operation content prediction unit 301 replaces <ContentID> of the cooperative operation content specified in step 6b with that of the current operation log. “A-xxxxxx” of <ContentID> in FIG. 25A is replaced with “B-xxxxxx” in FIG. 25B. That is, since this user has a record of copying the content “A-xxxxxx” to the PC after recording it on the HDD recorder in the past, when the event of recording the content “B-xxxxxx” occurs now, Predicts that it will be copied to a PC in the future. After presenting the prediction result to the user, steps 13d to 13g are executed.

As described above, according to the sixth embodiment, related operation logs and past cooperative operation contents received from other devices are grouped by a predetermined attribute, and the grouped related operation logs and current operation logs By replacing the different attribute values, the next operation behavior of the user is predicted, and the cooperative operation of the devices can be realized more easily.
In step 6c of the present embodiment, the operation has been described in which the prediction result is presented to the user, and the user selects the content of the cooperative operation. However, the user does not necessarily need to intervene, and the prediction result is directly used by another device. May be transmitted and controlled.

(Seventh embodiment)
The seventh embodiment is designed to detect a status change of a device and provide a service according to what the user is currently doing according to the status change. FIG. 26 shows a configuration diagram of the seventh embodiment. The difference from the first embodiment shown in FIG. 2 is that a device status detection unit 401 detects the status of a device at a predetermined timing, and a device status accumulation management unit accumulates and manages device status information related to the detected status. 402, a device status information transmitting unit 403 for transmitting device status information to another device, and a device status information receiving unit 404 for receiving device status information from another device.

The operation of the seventh embodiment configured as described above will be described with reference to the timing chart of FIG. In the example of FIG. 27, it is assumed that the processing procedures 7a and 7c are executed by the DTV, and the processing procedures 7b and 7d are executed by the PC.
First, in the processing procedure 7a, the status change of the device is detected by the device status detection unit 401 and the device status accumulation management unit 402, and the status of the device and the status change are determined by the device status information transmission unit 403 at a predetermined timing. Inform the equipment. Here, it is assumed that the DTV detects the start of a CM (Commercial Message) and transmits the status information to the PC. The detection of the CM start is simply performed by detecting a change from a monaural signal to a stereo signal.

  In the processing procedure 7b, the device status information receiving unit 404 receives status information (here, CM start information) transmitted from another device. With the reception of the status information as a trigger, the related operation log extraction unit 105 of the PC extracts an operation log from the operation log accumulation management unit 102, and returns this to the DTV. The operation log extracted at this time is, for example, a mouse operation log, and it is assumed that the mailer has been activated at the same time.

  In the processing procedure 7c, the DTV related operation log receiving unit 107 receives a mouse operation log from the PC. The DTV cooperation operation content determination unit 110 determines that this user is watching the TV, operates the mouse when he becomes a CM, and checks mail, and the cooperation operation content transmission unit 111 transmits The URL of the homepage to be executed and a message for starting the browser are transmitted to the PC. The URL for the CM can be extracted from the data broadcast, for example.

In the processing procedure 7d, the cooperative operation content receiving unit 112 of the PC receives the browser activation message from the DTV and the URL related to the CM as <ContentID>, and presents the homepage to the user.
As described above, according to the seventh embodiment, it is possible to detect a status change of a device and provide a service according to what the user is currently doing according to the status change.

(Eighth embodiment)
In the eighth embodiment, a device (for example, an MD component) having a limited hardware resource requests a device (for example, a PC) having a sufficient hardware resource to accumulate an operation log and perform a proxy process for the contents of a cooperative operation.

FIG. 28 is a block diagram of the operation log cooperative utilization device 10 in a device having a small number of hardware resources, and FIG. The difference from the first embodiment shown in FIG. 2 is that a device dependency setting unit 501 for proxy processing is added (FIGS. 28 and 29).

  Next, the operation of the device dependency setting unit 501 will be described. For example, a device with a low CPU speed and a small memory, such as an MD component, sets a dependency when checking out music downloaded from a PC to an MD. That is, the operation log in the MD component is transferred and stored in the PC every time it occurs, and the interpretation and storage of the operation logs of other devices related to the MD component are performed by the PC on behalf of the PC. This allows inexpensive devices to cooperate with other devices.

As described above, according to the eighth embodiment, a device having a limited hardware resource requests a device having a sufficient hardware resource to accumulate an operation log and perform a proxy process of a cooperative operation content. As a result, even inexpensive devices can easily cooperate with other devices.
In the case where user information such as a usage history and a profile is collectively managed by a service provider or a portable memory, services cannot be enjoyed in the event of a failure, and there is a high security and privacy risk.

On the other hand, according to the eighth embodiment, the operation logs of a plurality of devices are managed in a decentralized manner, and the interpreting function of the operation in which the interconnected devices cooperate with each other is alternately performed. Even if one of the devices is unable to communicate due to a failure or a failure, device cooperation according to the user's situation can be performed.
As described above, the operation log cooperative utilization device according to the present invention has been described based on the first to eighth embodiments, but the present invention is not limited to these embodiments.

  For example, an operation log cooperative utilization device having a configuration in which these embodiments are appropriately combined is also an embodiment of the present invention. As an example, as shown in the configuration example of FIG. 30, the present invention may be realized as an operation log cooperative utilization apparatus that combines the first to eighth embodiments.

  INDUSTRIAL APPLICABILITY The present invention can be used as devices connected to each other via a network, such as digital televisions, personal computers, portable information terminals, MD components, DVD / HDD recorders, and other network-connectable home appliances.
