  FIG. 6 is a flowchart showing an example of setting information acquisition processing executed by the central control unit 7 of the television receiver 1 shown in FIG. The setting information acquisition process is a process of the television receiver 1 as the requesting information processing apparatus for setting information, that is, environment data. When the television receiver 1 is connected to the network, the process proceeds to step S1.

  In step S1, an IP address for accessing a device on the network is acquired from a DHCP server existing on the network, for example, the router 44 shown in FIG. At this time, as the network setting information to be acquired in addition to the IP address, for example, a netmask that defines how many bits of the IP address are used for the network address, and a device that serves as a window for accessing computers on other networks There is information such as a default gateway indicating the DNS and a DNS (Domain Name Server) address that associates a domain name with an IP address.

  In step S2, an IP address under the same network is obtained from the acquired IP address and netmask, and a request for index data is transmitted by broadcast to the obtained IP address. That is, a request for index data is transmitted to an unspecified device in the same network. Since transmission is performed only to devices under the DHCP server, security between the devices under the DHCP is guaranteed.

  In step S3, when there is a response from a device in the same network, that is, when an index data file is transmitted, the index data file is received from one device among the devices that have transmitted the index data file. .

  In step S4, among the index data included in the received index data file, setting information indicated by one index data, that is, environment data, is information that can be used by the television receiver 1, that is, information that matches a predetermined condition. Determine whether or not. For example, the determination is made by comparing the type of environmental data indicated by the index data with the type of environmental data to be set in the television receiver 1. When the information is available, for example, when the environmental data type is the same, the process proceeds to step S5. When the information is not usable, for example, the environmental data type is not the same, Proceed to step S6.

  In step S5, the data file name of the environmental data that matches the type of the environmental data is obtained from the index data, and the data file having the obtained data file name is downloaded. To download a data file, first, the device that sent the index data is requested to send the data file having the data file name of the environmental data that matches the type of the environmental data. Next, it is realized by receiving a data file transmitted from a device that has requested transmission of the data file.

  The downloaded data file is stored in the environmental data storage unit 9c. When environment data of the same type is already stored in the environment data storage unit 9c, overwrite registration, that is, the data of the downloaded data file is stored in the environment data area that has already been stored. Therefore, the environmental data that has already been stored is deleted. When environmental data of the same type is not stored in the environmental data storage unit 9c, additional registration, that is, environmental data of the downloaded data file is newly stored in the environmental data storage unit 9c.

  In step S6, it is determined whether or not all setting information, that is, environmental data has been checked. That is, among the index data included in the acquired index data file, the environment data type indicated by each index data is compared for all index data, and the data file is downloaded for the environmental data having the same environmental data type. Determine whether or not. If all data files have been downloaded for environmental data with the same environmental data type, the process proceeds to step S7. If all data files have not been downloaded for environmental data with the same environmental data type, the process proceeds to step S4. Return. When the process returns to step S4, it is determined whether or not the environmental data indicated by the next index data among the index data included in the index data file is information that can be used by the television receiver 1.

  In step S7, it is determined whether or not an index data file has been received for all devices that have responded in step S3. When the index data file has not been received for all the devices that have responded, the process returns to step S3, and the index data file is received for the next device among the devices that have responded. When index data files are received for all devices that have responded, the process ends.

  In the above-described embodiment, an example of broadcasting to all IP addresses in the same network has been shown. However, the television receiver 1 has a function of specifying an IP address or a set of IP addresses for requesting index data. In some cases, a request for index data may be transmitted by specifying the IP addresses of a plurality of devices connected to the same network by multicast, that is, a plurality of devices connected to the same network.

  FIG. 7 is a flowchart showing an example of setting information transmission processing executed by the central control unit 7 of the television receiver 1 shown in FIG. The setting information transmission process is a process executed when the television receiver 1 functions as a requested information processing apparatus. When a request for index data is transmitted from a device that is another information processing apparatus, the process proceeds to step T1.

  In step T1, it is determined whether an index data request has been received, that is, whether an index data file transmission request has been received. If there is an index data file transmission request, the process proceeds to step T2, and if there is no index data file transmission request, the process proceeds to step T3. In step T2, the index data file stored in the data memory 9 is transmitted to the device that has requested transmission of the index data file.

  In step T3, it is determined whether or not there is a data file transmission request. If there is a data file transmission request, the process proceeds to step T4. If there is no data file transmission request, the process ends. In step T4, the data file requested to be transmitted is transmitted to the device that has requested transmission of the data file, and the process ends.

  The list request information for requesting list information is, for example, a request for index data, and the environmental data request information is, for example, a transmission request for a data file.

  The setting information acquisition process shown in FIG. 6 and the setting information transmission process shown in FIG. 7 will be described for the information processing system 40 shown in FIG. The television receiver 1 is the information processing apparatus on the request side, and the digital recorder 41 and the personal computer 42 are the information processing apparatuses on the request side.

  The digital recorder 41 and the personal computer 42 are already connected to the LAN network. The digital recorder 41 is set with channel data, that is, channel setting and keyword data, that is, keyword setting, and the personal computer 42 is set with bookmark data, that is, bookmark setting. Is set. Hereinafter, channel data is referred to as channel setting, keyword data is referred to as keyword setting, and bookmark data is referred to as bookmark setting.

  When the television receiver 1 is connected to the LAN network, the television receiver 1 accesses the router 44 and acquires network setting information (step S1). The television receiver 1 extracts an IP address in the same network from the acquired network setting information and broadcasts it. That is, a request for index data is transmitted to all IP addresses existing in the same network (step S2).

  Other devices on the network, that is, the digital recorder 41, the personal computer 42, and the router 44 receive the index data request (step T1). The digital recorder 41 and the personal computer 42 transmit the index data file stored in each device (step T2). However, since the router 44 is not an information processing apparatus that can transmit environment data, the router 44 does not transmit an index data file.

  The television receiver 1 first acquires an index data file from the digital recorder 41 (step S3). The index data file of the digital recorder 41 indicates that the digital recorder 41 stores data files for channel setting and keyword setting. In the television receiver 1, whether the type of channel setting in the environmental data indicated by the index data included in the index data file of the digital recorder 41 matches the type of environmental data set in the television receiver 1. It is determined whether or not (step S4).

  Since the television receiver 1 also needs to perform channel setting, the type of environmental data called channel setting of the digital recorder 41 matches the type of environmental data of the television receiver 1, and the television receiver 1 Is requested to the digital recorder 41. When there is a request for transmission of channel setting from the television receiver 1 (step T3), the digital recorder 41 transmits a data file of channel setting (step T4). The television receiver 1 downloads the channel setting data file transmitted from the digital recorder 41 and stores it in the data memory 9 (step S5).

  The television receiver 1 determines whether or not the data file has been downloaded for all the environmental data indicated by the index data included in the index data file acquired from the digital recorder 41. Since the keyword setting data file has not yet been downloaded (step S6), in the television receiver 1, the type of environmental data called keyword setting of the digital recorder 41 matches the type of environmental data of the television receiver 1. It is determined whether or not to perform (step S4).

  Since the type of environmental data called keyword setting of the digital recorder 41 matches the type of environmental data of the television receiver 1, the television receiver 1 requests the data file for keyword setting from the digital recorder 41. When the digital recorder 41 requests the keyword-set data file from the television receiver 1 (step T3), the digital recorder 41 transmits the keyword-set data file (step T4). The television receiver 1 downloads the keyword setting data file transmitted from the digital recorder 41 and stores it in the data memory 9 (step S5).

  The television receiver 1 determines whether or not the data file has been downloaded for all the environmental data indicated by the index data included in the index data file acquired from the digital recorder 41. Since all environment data of the digital recorder 41, that is, data files for channel setting and keyword setting have been downloaded (step S6), the television receiver 1 receives all index data files from the device to which the index data file is transmitted. It is determined whether or not it has been received. Since the television receiver 1 has not yet received the index data file from the personal computer 42 (step S7), the television receiver 1 acquires the index data file from the personal computer 42 (step S3).

  The index data file of the personal computer 42 indicates that the personal computer 42 stores a bookmark setting data file. The television receiver 1 determines whether or not the type of environmental data called bookmark setting in the environmental data indicated by the index data included in the index data file of the personal computer 42 matches the type of environmental data of the television receiver 1. Is determined (step S4).

  Since the type of environmental data of bookmark setting that the personal computer 42 has matches the type of environmental data of the television receiver 1, the television receiver 1 requests the personal computer 42 for a data file of bookmark setting. When there is a request for a bookmark setting data file from the television receiver 1 (step T3), the personal computer 42 transmits the bookmark setting data file (step T4). The television receiver 1 downloads the bookmark setting data file transmitted from the personal computer 42 and stores it in the data memory 9 (step S5).

  The television receiver 1 determines whether or not the data file has been downloaded for all the environmental data indicated by the index data included in the index data file acquired from the personal computer 42. Since all the environmental data of the digital recorder 41, that is, the bookmark setting data file has been downloaded (step S6), the television receiver 1 determines whether or not all the index data files have been received. The television receiver 1 ends because it has received the index data files from the digital recorder 41 and the personal computer 42 (step S7).

  As described above, among the operation condition information received from other information processing devices, the operation condition information of the operation condition type that matches the device type of the own information processing device is stored as the operation condition information of the own information processing device. Even when operating condition information is received from information processing apparatuses of different device types, it is possible to select and use operating condition information suitable for the information processing apparatus. Therefore, even if the operation condition is acquired from a device that is an information processing apparatus having a different device type, an operation condition that matches the operation condition type can be set.

  Further, when requesting the operating condition information stored in another information processing apparatus, the list information indicating the list of the operating condition information is requested first, and the list information returned from the other information processing apparatus in response to the request Of the operation condition information indicated by the list information, the operation condition request information requesting transmission of the operation condition information that matches the predetermined condition is transmitted, and the response is returned in response to the operation condition request information. Since the operating condition information is stored as the operating condition information of the information processing apparatus, the operating condition information set for other devices can be acquired with a smaller amount of information of the operating condition information transmitted. Therefore, it is possible to more efficiently acquire the operating condition information set for the device that is another information processing apparatus.

  In the above-described embodiment, channel data, keyword data, and bookmark data are described as environment data. However, setting information indicating the operating conditions of the application program, for example, setting information for spreadsheet software and word processing software, and for personal computers OS (Operating System) desktop screen setting information may be used.

  As described above, the operation condition information includes at least one of channel setting information for setting a television broadcast channel, preference information related to the user's preference, and setting information indicating an operation condition of the application program. Channel setting information, preference information, and application program setting information set for other devices can be set and used as operation condition information for the device itself. Therefore, when a device that is an information processing apparatus is newly connected to the network, it is not necessary to manually set the setting information.

  FIG. 8 is a flowchart showing a second example of the setting information acquisition process shown in FIG. Steps S1 to S4 in the flowchart shown in FIG. 6 correspond to Steps U1 to U4 in the flowchart shown in FIG. 8, respectively. Steps S5 to S7 correspond to Steps U6 to U8, respectively. Step U5 is added. A description of the processing of the steps corresponding to the flowchart shown in FIG. 6 is omitted.

  In step U5, it is determined whether or not the update date and time included in the index data having the same environmental data type is newer than the update date and time included in the index data of the same type of environmental data stored in the environmental data storage unit 9c. to decide. When the update date / time is new, the process proceeds to step U6 to download the data file. When the update date is not new, the process proceeds to step U7 without downloading the data file. When the index data is not stored in the environmental data storage unit 9c, it is determined that the update date is new.

  For example, a digital recorder 41 in which a channel setting with a channel setting update date of 2004/03/12 is connected to the network, and a channel setting with a channel setting update date of 2003/12/01 is set. A case where the television receiver 1 is connected to a network will be described.

  In the television receiver 1, the channel setting update date / time included in the index data acquired from the digital recorder 41 is greater than the channel setting update date / time included in the index data stored in the environmental data storage unit 9 c by the television receiver 1. Since it is new, the channel setting data file is downloaded from the digital recorder 41, and the channel setting stored in the environment data storage unit 9c is updated with the downloaded data file.

  If the update date and time of the channel setting of the digital recorder 41 is older than 2003/12/01, the channel setting stored in the environment data storage unit 9c is not updated.

  As described above, the time indicated by the update time information included in the operation condition information received from another information processing apparatus is greater than the time indicated by the update time information included in the operation condition information stored in the storage unit of the information processing apparatus. When new, the operation condition information received from another information processing apparatus is stored in the storage means of the own information processing apparatus, so that it is possible to prevent old operation condition information from being set. That is, for example, like preference information, even if the same user changes the preference information by changing the preference, old preference information is not set by mistake.

  FIG. 9 is a flowchart showing a third example of the setting information acquisition process shown in FIG. Steps S1 to S4 in the flowchart shown in FIG. 6 correspond to Steps V1 to V4 in the flowchart shown in FIG. 9, respectively. Steps S5 to S7 correspond to Steps V7 to V9, respectively. Step V5 and step V6 are added. A description of the processing of the steps corresponding to the flowchart shown in FIG. 6 is omitted.

  Step V5 is the same type of environmental data stored in the environmental data storage unit 9c by the owner indicated by the member information of the owner (hereinafter referred to as owner information) included in the index data and having the same type of environmental data. It is determined whether or not it is the same as the owner indicated by the owner information included in the index data. When the owners are not the same, the process proceeds to step V6, and when the owners are the same, the process proceeds to step V7 to download the data file and store the downloaded data file in the environmental data storage unit 9c. When index data of the same type of environmental data is not stored in the environmental data storage unit 9c, it is determined that the owners are the same.

  In step V6, it is determined whether or not the setting information can be set by a plurality of owners, that is, environmental data. If the environment data can be set by a plurality of owners, the process proceeds to step V7, where the data file is downloaded, and the downloaded data file is stored in the environment data storage unit 9c. If the setting information is not settable by a plurality of owners, the process proceeds to step V8 without downloading the data file.

  For example, a digital recorder 41 in which channel settings and keyword settings having owner information whose owner name is “akira” is connected to the network, and owner information whose owner name is “akira” A case will be described in which the television receiver 1 in which the channel setting and the keyword setting are set is connected to the network.

  In the television receiver 1, the channel setting owner name “akira” included in the index data acquired from the digital recorder 41 is included in the index data stored in the environmental data storage unit 9c by the television receiver 1. Since it is the same as the name of the setting, the channel setting data file is downloaded from the digital recorder 41, and the channel setting stored in the environment data storage unit 9c is updated with the downloaded data file.

  Since the owner name is also the same for the keyword setting, the keyword setting data file is downloaded from the digital recorder 41, and the keyword setting stored in the environment data storage unit 9c is updated with the downloaded data file.

  If the owner name set in the channel setting and keyword setting of the digital recorder 41 is “papa”, the owner names do not match. Since the channel setting is not setting information that can be set by a plurality of owners, the channel setting data file is not downloaded from the digital recorder 41. Since the keyword setting is setting information that can be set by a plurality of owners, the keyword setting data file is downloaded from the digital recorder 41, and the keyword setting stored in the environment data storage unit 9c is downloaded to the downloaded data file. Update with.

  Thus, when the administrator information included in the operation condition information received from another information processing apparatus matches the administrator information included in the operation condition information stored in the storage unit of the information processing apparatus, Since the operating condition information received from the information processing apparatus is stored in the storage means of the information processing apparatus, it is possible to prevent the setting of the operating condition information of another administrator. That is, for example, it is possible to prevent the already set preference information from being updated with the preference information of other users having different preferences.

  In the above-described embodiment, the setting information is updated by using the update date and time and the owner information separately, but the setting information may be updated by combining them. For example, the owner information is checked first, and when the owner information matches, it is updated based on the update date and time, and when the owner information does not match, it is updated without checking the update date and time.

  FIG. 10 is a flowchart showing a fourth example of the setting information acquisition process shown in FIG. In the above-described embodiment, the television receiver 1 stores the environment data downloaded from other devices, that is, the setting information in the environment data storage unit 9c and operates based on the stored setting information. In the example of 4, the setting information downloaded from another device is temporarily stored as temporary setting information in the environment data storage unit 9c, and the television receiver 1 is operated based on the stored temporary setting information. It is.

  Steps S1 to S4 in the flowchart shown in FIG. 6 correspond to Steps W1 to W4 in the flowchart shown in FIG. 10, respectively. Steps S6 to S7 correspond to Steps W6 to W7, respectively. Step S5 is replaced with Step W5, and Steps W8 to W11 are added. A description of the processing of the steps corresponding to the flowchart shown in FIG. 6 is omitted.

  In step W5, the downloaded data file is stored in the environmental data storage unit 9c as temporary setting information. In step W8, it is determined whether there is temporary setting information. When there is temporary setting information, the process proceeds to step W9, and when there is no temporary setting information, the process ends.

  In step W9, information for inquiring the user whether to use temporary setting information is displayed on the monitor 4. In step W10, it is determined whether or not the instruction from the user is an instruction to use temporary setting information. When the instruction from the user instructs the use of the temporary setting information, the process proceeds to step W11, and when the instruction from the user does not instruct the use of the temporary setting information, the process ends. In Step W11, the television receiver 1 is set based on the temporary setting information stored in the environment data storage unit 9c, and the process ends.

  FIG. 11 is a diagram showing an example of the temporary setting information instruction screen 88 displayed on the monitor 4 shown in FIG. The temporary setting information instruction screen 88 is a screen displayed in step W9 shown in FIG. The temporary setting information instruction screen 88 includes, for example, a “temporary setting information instruction screen” as a screen title, information for inquiring whether or not to use temporary setting information, “Do you use temporary setting information?”, And “use Two types of buttons, “Yes” button 88a and “Not use” button 88b, are displayed.

  The user instructs to use temporary setting information by selecting the “use” button 88a, and instructs not to use temporary setting information by selecting the “not use” button 88b. Can do. In this fourth example, it is possible to select whether or not to use temporary setting information depending on the user's selection. When there is temporary setting information, the operation of the temporary setting information is performed without the user's selection. You may make it operate | move on conditions.

  The temporary setting information stored in the environmental data storage unit 9c may be deleted after the television receiver 1 is operated based on the temporary setting information, or by the operation of the user or the restart of the apparatus. It may be erased at the timing. When the temporary setting information is deleted, the television receiver 1 operates by setting the setting information stored in the environmental data storage unit 9c.

  Table 5 shows the data structure of the index data file in which the index data of the temporary setting information is set. A member of a temporary setting flag indicating that there is temporary setting information is added to a member of index data for setting temporary setting information. Further, the identification information of the index data of the temporary setting information is described in the “data” column of the temporary setting flag member.

  For example, when the index data of the temporary setting information is set in the index data whose identification information is “data 1”, “data 1 temporary setting flag” is described as the fifth member of “data 1”. In the “data” column of “data 1 temporary setting flag”, identification data “data 5” of index data of temporary setting information is described.

  The index data of the temporary setting information “data 5” is composed of four types of members “data 5 type”, “data 5 data file name”, “data 5 owner”, and “data 5 update date / time”. It is. The contents of “type” and “size” of “data 5” are the same as those of data 1. The “data” of each member of “data 5 type”, “data 5 data file name”, “data 5 owner”, and “data 5 update date / time” is “channel setting”, “channelichiji.dat”, “ akira "and" 2004/11/01 ".

  As described above, the information processing apparatus includes the operation condition information received by the transmission / reception means of the information processing apparatus, in addition to the first storage means that already stores the operation condition information. Among the operating condition information received by the transmission / reception means of the information processing apparatus, a third storage means for storing operating condition information that matches a predetermined condition, for example, the environmental data storage section 9c, is temporarily included. It is possible to operate under the operating conditions indicated by the operating condition information stored in the storage means. Therefore, it can temporarily operate under the operating conditions set in the equipment that is another information processing device, so it can be compared with the operation under the operating conditions set in the other equipment.
