"Display character data", "Display image data" for displaying service guidance screens, "Phonetic character string data" and "compressed voice data" for service voice guidance, related to the contents information "URL information" indicating the address of the storage location of the Web page that provides information to be performed, "affiliated parking information" indicating a partner parking lot other than the target location, and "icon display image when displaying the target location on the map screen" Data "and the like.

  As described above, the “preference information” classified into the ID 80 includes “preference information version information” indicating the version of the preference information, “item number”, “display text”, and “display” for each item indicating the content classification. "Nest", "Default value", "Speech character string", etc. are included.

Next, the operation will be described.
FIG. 10 is a flowchart for explaining the flow of processing in the center device 30, the roadside wireless device 20, the DSRC unit 3 and the control unit 4 of the vehicle-mounted device 10 when distributing content information.
As shown in FIG. 10, when the engine of the vehicle C is started and the power of the vehicle-mounted device 10 is turned on (step S1), the control unit 4 generates the characteristic information of the vehicle-mounted device 10 and updates the storage unit 3c. Write to the link information storage area ME (step S2). The characteristic information is obtained by the control unit 4 inquiring about each item such as the display unit 1e about items that have been negotiated with the center device 30 in advance, or by reading information stored in the storage unit 1f in advance. get. Then, the control unit 4 encodes the acquired information and writes the code in a corresponding area of the uplink information storage area ME. Actually, control information for instructing writing is output to the DSRC control unit 3a, and the DSRC control unit 3a writes the information to the uplink information storage area ME.

  Thereafter, when the vehicle C starts traveling and enters the mutual communication area Z of the roadside apparatus 20 (area-in), the roadside apparatus 20 detects the vehicle C and connects to the DSRC unit 3 of the vehicle-mounted device 10 through DSRC communication. Processing is started (steps S3a and S3b). That is, when a DSRC radio wave is transmitted and a response from the vehicle-mounted device 10 is obtained, a communication path is established. When the communication path is established, the roadside apparatus 20 transmits notification information indicating that the connection is completed to the center apparatus 30 (step S4a). On the other hand, the DSRC unit 3 of the vehicle-mounted device 10 outputs notification information indicating that the connection has been completed to the control unit 4 (step S4b).

Next, the DSRC unit 3 transmits the characteristic information written in the uplink information storage area ME to the roadside apparatus 20 (step S5). The characteristic information is transmitted to the center apparatus 30 via the roadside apparatus 20.
In the center apparatus 30, when the characteristic information is received by the communication unit 35, the control unit 31 determines whether the user of the vehicle-mounted device 10 is a member of the distribution service based on the vehicle-mounted device ID included in the received characteristic information. (Step S6).

  The control unit 31 of the center device 30 does not match the received vehicle-mounted device ID among the vehicle-mounted device IDs of all members of the distribution service registered in the member database stored in the storage unit 34, and the vehicle-mounted device If it is determined that 10 users are non-members (step S6; NO), the non-member content information is read from the storage unit 34 and distributed to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 ( Step S21). When the distribution ends, the control unit 31 of the center apparatus 30 generates message information for notifying the end of distribution and transmits the message information to the vehicle-mounted device 10 (step S22), and the process in the center apparatus 30 ends. Non-member content information is information on general contents such as public advertisement information such as train delay information and tax payment notice information.

  On the other hand, if the vehicle-mounted device ID that matches the received vehicle-mounted device ID is registered in the member information database stored in the storage unit 34 and it is determined that the user of the vehicle-mounted device 10 is a member (step S6; YES), The control unit 31 of the center device 30 distributes the default content information for members to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step S7). The default content information for members is, for example, Welcom screen information indicating the start of distribution of content information.

  Moreover, the control part 31 polls with respect to the onboard equipment 10 regularly (step S8, S11), and requests | requires transmission of the uplink information written in the uplink information storage area ME.

  When content information is received via the roadside apparatus 20, the control unit 4 of the vehicle-mounted device 10 is included in the carrier code included in the received content information and the uplink information stored in the storage unit 1f. It is determined whether or not the distribution company that has distributed the received content information is a contracted company by collating the received company code (step S9). If it is determined that the distribution company that distributed the received content information is not a contracted company (step S9; NO), the control unit 4 proceeds to the process of step S18 and notifies the end of distribution from the center device 30. In response to the reception of the message information, whether or not all the content information is complete, whether the data of the received content information is all normal, etc. are inspected (step S18), and the received content information is stored in the storage unit 1f. Save (step S19). And the control part 4 memorize | stores the reception history information of content information in the memory | storage part 1f (step S20), and complete | finishes the process in the control part 4. FIG. In addition, about the content information from the provider which has not contracted, you may abbreviate | store the reception log information.

  On the other hand, if it is determined that the distribution company that distributed the received content information is a contracted company (step S9; YES), the control unit 4 sends uplink information corresponding to the company code from the storage unit 1f. Read and write to the uplink information storage area ME (step S10).

  When the control unit 4 writes the uplink information, the DSRC unit 3 transmits the uplink information stored in the uplink information storage area ME according to the polling from the center device 30 to the roadside device 20. Is transmitted to the center device 30 via the network (step S12).

  In the center device 30, when uplink information is received via the communication unit 35, the control unit 31 temporarily stores the received uplink information and also causes the communication unit 35 to pass through the roadside radio device 20. An uplink information release request is transmitted to the vehicle-mounted device 10 (step S13). When receiving the uplink information release request transmitted from the center apparatus 30 via the roadside apparatus 20, the control unit 4 of the vehicle-mounted device 10 uplinks the uplink information written in the uplink information storage area ME in step S10. The information is deleted from the information storage area ME (step S14).

The control unit 31 of the center apparatus 30 performs a regenerator change check process based on the received uplink information (step S15).
FIG. 11 is a flowchart showing the regenerator change check process executed by the control unit 31 of the center apparatus 30 in step S15 of FIG.

  In the player change check process, first, the control unit 31 acquires the vehicle-mounted device ID from the received uplink information (step S101). Next, the control unit 31 refers to the vehicle-mounted device table 342, acquires the car navigation unit model number information stored in association with the acquired vehicle-mounted device ID, and substitutes it into the variable X (step S102). The car navigation unit model number information substituted into the variable X is the car navigation unit model number information included in the uplink information transmitted at the previous communication. In the initial communication, the vehicle-mounted device ID and the car navigation unit model number information are not stored in the vehicle-mounted device table 342.

  Next, the control unit 31 acquires car navigation unit model number information included in the received uplink information and substitutes it into the variable Y (step S103). The car navigation unit model number information that is substituted for this variable Y is the current (current) car navigation unit model number information in the in-vehicle device 10 that is the uplink information transmission source.

  Next, the control unit 31 determines whether or not a value is assigned to the variable X, and if it is determined that no value is assigned to the variable X (step S104; NO), the on-board unit ID acquired in step S101 and The car navigation unit model number information assigned to the variable Y is associated and additionally stored in the vehicle-mounted device table 342 (step S105), and the process proceeds to step S16 in FIG.

  On the other hand, if it is determined that a value is assigned to the variable X (step S104; YES), the control unit 31 determines whether or not the value assigned to the variable X matches the value assigned to the variable Y. Judgment is made (step S106). If it is determined that the value assigned to the variable X matches the value assigned to the variable Y (step S106; YES), the control unit 31 adds the car navigation unit model number information at the previous communication and the current car navigation unit model number information. It is determined that there is no change, and the process proceeds to step S16 in FIG.

  If it is determined that the value assigned to the variable X and the value assigned to the variable Y do not match (step S106; NO), the control unit 31 refers to the regenerator table 341 and is assigned to the variable X. Information indicating the type of the player 1h corresponding to the car navigation unit model number information (player information) is acquired and substituted into the variable A (step S107). Further, the control unit 31 refers to the player table 341, acquires player information indicating the type of the player 1h corresponding to the car navigation unit model number information assigned to the variable Y, and assigns it to the variable B ( Step S108).

  Next, the control unit 31 determines whether or not the value assigned to the variable A matches the value assigned to the variable B (step S109). That is, it is determined whether or not the type of the regenerator 1h of the in-vehicle device 10 at the time of the previous communication is the same as the current type of the regenerator 1h of the on-vehicle device 10. If it is determined that the value assigned to the variable A matches the value assigned to the variable B (step S109; YES), the control unit 31 proceeds to the process of step S113, and in step S101 in the vehicle-mounted device table 342. The car navigation unit model number corresponding to the acquired vehicle-mounted device ID is updated to the car navigation unit model number information substituted into the variable Y (step S113), and the process proceeds to step S16 in FIG.

  When determining that the value assigned to the variable A and the value assigned to the variable B do not match (step S109; NO), the control unit 31 obtains the preference information of the user of the vehicle-mounted device 10 from the received uplink information. Obtain (step S110). Then, in the acquired preference information, it is determined whether or not an item assigned to the variable A and corresponding to the type of the player 1h at the previous communication is set (selected) as a favorite item (step S111). . If it is determined that “1” is not set in the item corresponding to the type of the player 1h at the previous communication, that is, the item corresponding to the type of the player 1h at the previous communication is not set as a preference item. (Step S111; NO), the control unit 31 proceeds to the process of Step S113, and the car navigation unit model number information in which the car navigation unit model number information corresponding to the vehicle-mounted device ID acquired in Step S101 in the vehicle-mounted device table 342 is substituted into the variable Y. (Step S113), and the process proceeds to step S16 in FIG.

  If it is determined that the item corresponding to the type of the player 1h at the previous communication is set as a favorite item (step S111; YES), the control unit 31 sets the current player 1h assigned to the variable B. The default value of the item corresponding to the type is changed to “1”, that is, preference information added as a preference item is generated, stored in the data format ID 80 shown in FIG. The part 35 delivers to the vehicle-mounted device 10 via the roadside apparatus 20 (step S112). Then, the car navigation unit model number information corresponding to the vehicle unit ID acquired in step S101 in the onboard unit table 342 is updated to the car navigation unit model number information substituted into the variable Y (step S113), and the process proceeds to step S16 in FIG. .

  Specifically, in step S111, the preference information of the same version as the preference information included in the received uplink information is read from the storage unit 34, and the player information substituted for the variable A matches the display text. Search for. Then, in the preference information included in the received uplink information, it is determined whether or not the setting value corresponding to the item number of the searched item is “1”. It is determined that the item corresponding to the type of the player 1h is set (selected) as a favorite item. In step S112, in the preference information read from the storage unit 34, the default value of the setting value “1” item of the preference information included in the received uplink information is set to “1”, and the default values of the other items are set. While setting the value to “0” and changing the default value of the item for which the player information assigned to the variable B matches the display text to “1”, the preference information for user distribution is created, The created preference information is stored in the content information data format ID 80 shown in FIG.

  By the processing of step S111 and step S112, for example, when the type of the player 1h at the previous communication of the vehicle-mounted device 10 is “DVD” and the type of the current player 1h is “BD”, the uplink information is included in the uplink information. If the item “DVD” is selected in the included preference information, the item “BD” is automatically set as a favorite item. That is, when the user desires to view content information related to the player 1h mounted on the vehicle-mounted device 10, if the type of the player 1h of the vehicle-mounted device 10 is changed, the player 1h after the change is changed. The item corresponding to the type of item is automatically added to the item that is preferred. Therefore, the user can save the trouble of setting the item corresponding to the type of the player 1h after the change on the preference item setting screen G1 as a preference item.

  In step S16 of FIG. 10, the control unit 31 organizes content information to be distributed based on the received uplink information, and distributes the content information to the vehicle-mounted device 10 via the roadside apparatus 20 by the communication unit 35 (step S16). ). In step S16, for example, the preference information of the received uplink information is referred to, and the content information classified into the item preferred by the user among the content information stored in the storage unit 34 is selected as the content to be distributed. Then, the corresponding content information is read from the storage unit 34 and distributed to the vehicle-mounted device 10. If the content information has already been distributed in step S112 of FIG. 11, it may not be distributed, or another content information may be further distributed.

  When the distribution of the content information is completed, the control unit 31 of the center device 30 generates message information notifying the end of the distribution, and transmits the message information to the in-vehicle device 10 via the roadside wireless device 20 by the communication unit 35 (Step S17).

  In the vehicle-mounted device 10, when the content information distributed from the center device 30 and the distribution end notification are received via the roadside wireless device 20, the control unit 4 of the vehicle-mounted device 10 has received whether or not all the content information is complete. The content information data is inspected to determine whether it is all normal (step S18), and the received content information is stored in the storage unit 1f (step S19). Further, the reception history information is stored in the storage unit 1f (step S20). Specifically, the received information code of the received content information is written in the uplink information corresponding to the provider code stored in the storage unit 1f.

  When the vehicle-mounted device 10 is moved out of the mutual communication area Z (area out) and communication with the roadside apparatus 20 is interrupted for a certain time or more, a series of information distribution processing ends.

  When the content information is received and stored from the center apparatus 30 by the process shown in FIG. 10, the control unit 4 of the vehicle-mounted device 10 can play back the content and responds to the user's instruction input via the input unit 1d. Play content.

  As described above, according to the information distribution system 100 in the first embodiment, when the control unit 31 of the center apparatus 30 receives the uplink information from the vehicle-mounted device 10, the received uplink information is included in the received uplink information. Based on the car navigation unit model number information of the vehicle-mounted device 10 included and the car navigation unit model number information at the time of the previous communication of the vehicle-mounted device 10 stored in the vehicle-mounted device table 342, the playback device 1h mounted on the vehicle-mounted device 10 Determine whether the type has changed. When the type of the player 1h is changed, the control unit 31 determines whether or not the item corresponding to the type of the player 1h at the previous communication is set as a preference item in the preference information included in the uplink information. If the item is set as a favorite item, preference information in which an item corresponding to the type of the changed player 1h is added to the favorite item is generated and transmitted to the vehicle-mounted device.

  Therefore, when there is a change in the type of the player 1h mounted on the vehicle-mounted device 10, it is possible to receive content information corresponding to the type of the player 1h after the change without any user effort. Become. For example, it becomes possible for the user to obtain information on hardware (for example, a recorder) and software according to the type of the player 1h after the change.

  In the above embodiment, the item corresponding to the type of the player 1h before the change is left as a favorite item, but it may be removed from the favorite item.

<Second Embodiment>
The second embodiment according to the present invention will be described below.
In the first embodiment, the center device 30 checks whether or not the type of the regenerator 1h of the car navigation unit 1 of the vehicle-mounted device 10 has been changed, and if there has been a change, the type of the regenerator 1h after the change. The item corresponding to is added to the item that the user likes, and the preference information is updated and distributed to the vehicle-mounted device 10. In the second embodiment, when the car navigation unit 1 of the vehicle-mounted device 10 is changed, the vehicle-mounted device 10 checks whether or not the type of the regenerator 1h is changed, and if there is a change, the change is made. The item corresponding to the type of the subsequent player 1h is added to the item that the user likes to update the preference information.

  In 2nd Embodiment, the memory | storage part 1f of the onboard equipment 10 has the regenerator table 111 similar to the regenerator table 341 shown in FIG. 7 memorize | stored in the center apparatus 30 in 1st Embodiment. ing.

  Further, the storage unit 1f stores a similar preference item table 112 shown in FIG. Here, as described above, each item of the preference information and its display text can be set by the distributor as described above. Therefore, even for items that show the same content, the display text may differ depending on the distributor. For example, it is assumed that information (text information) indicating the type of the player 1h specified by the car navigation unit model number information and the player table 111 is “BD”. The distribution company may use “BD” as the display text of the item corresponding to the type of the player 1h in the preference information, but “Blu-ray”, “Blu-ray Disc”, “Blu-ray Disc”. Other display texts may be used. Therefore, in the vehicle-mounted device 10, the display text (“preference item”) of the item corresponding to each player information included in the player table 111 and the display text (“preference item”) indicating the item having the same content but different notation. “Similar preference item”) is stored in advance in a similar preference item table 112 as shown in FIG. 12 so that items having the same contents but different notations can be discriminated.

  Since the configuration of each device and the data configuration of content information and uplink information in the other second embodiment are substantially the same as those in the first embodiment, the description will be referred to, and hereinafter the second embodiment. Will be described.

When the control unit 4 of the vehicle-mounted device 10 is instructed to store the car navigation unit model number information or the like by operating the input unit 1d from the menu screen, the car navigation unit model number included in the uplink information stored in the storage unit 1f. It has a function of storing information, a provider code of a distributor, etc. in the storage unit 3c of the DSRC unit 3 or in the external memory device ED via the memory card I / F 1i.
Before the change of the car navigation unit 1, the user inputs a storage instruction such as the car navigation unit model number information by the input unit 1d, and the model number information of the car navigation unit before the change is stored in the storage unit 3c of the DSRC unit 3 or the memory card I / The data is stored in the external memory device ED via F1i.

  After the car navigation unit 1 is changed, when the execution instruction for the player change check is input by the operation of the input unit 1d from the menu screen by the user, the control unit 4 executes the player change check process. Note that the regenerator change check process in the second embodiment is referred to as a regenerator change check process B in order to distinguish it from the process in the first embodiment.

FIG. 13 is a flowchart showing the regenerator change check process B executed by the control unit 4 of the vehicle-mounted device 10.
In the player change check process B, first, the control unit 4 acquires the car navigation unit model number information before the change from the storage unit 3c or from the external memory device ED via the memory card I / F 1i (step T1). . Next, the control unit 4 refers to the player table 111 stored in the storage unit 1f, and acquires information (player information) indicating the type of the player 1h corresponding to the acquired car navigation unit model number information. Then, the player information that was installed in the car navigation unit 1 before the change is acquired and substituted into the variable A (step T2).

  Next, the control unit 4 refers to the player table 111 to obtain player information corresponding to the current (changed) car navigation unit model number information of the car navigation unit 1, and substitutes it into the variable B (step T3). By comparing the value of the variable A and the value of the variable B, it is determined whether or not the type of the regenerator 1h before and after the change is the same. When it is determined that A = B and the type of the regenerator 1h before and after the change is the same (step T4; YES), the control unit 4 ends this process.

  On the other hand, if it is determined that the type of the regenerator 1h before and after the change is not the same instead of A = B (step T4; NO), the control unit 4 substitutes the number of distributors contracted for the variable m (step S4) T5), 1 is substituted into the variable n (step T6). Next, the control unit 4 compares the value of the variable m with the value of the variable n, and when n ≦ m (step T7; YES), executes the preference information update process of the nth distributor (step S7). T8).

FIG. 14 is a flowchart showing the preference information update process of the nth delivery operator executed by the control unit 4 in step T8 of FIG.
In the preference information update process of the nth distributor, the control unit 4 first executes a selection check process (step T11).

FIG. 15 is a flowchart showing the selection check process executed by the control unit 4 in step T11 of FIG.
In the selection check process, the control unit 4 first substitutes 1 for a variable i, 1 for a variable j, and false for a variable ret as an initial value (step T101).

  Next, the control unit 4 retrieves and reads out the content information including ID80 from the content information of the n-th distribution provider stored in the storage unit 1f (step T102), and the preference stored in the ID80 in the variable N The number of items of information (preference items) (the number of preference items) is substituted (step T103). Here, whether or not the content information of the n-th delivery company is determined by the company code of ID01. Further, when a plurality of pieces of content information including the ID 80 of the nth distributor are stored, the latest version of the content information is read out. If the content information including the ID 80 of the nth distributor does not exist, that is, has not yet been downloaded, 0 is substituted for the number of preference items.

  Next, the control unit 4 refers to the similar preference item table 112, and the playback device information before the change (value of the variable A) stored in the variable A and the similar preference item (value of the playback device information) associated with the playback device information. The total number of these is hereinafter referred to as a preference item candidate) is counted and substituted into the variable M as the number of preference item candidates (step T104).

  Next, the control unit 4 compares the value of the variable i with the value of the variable N. If i ≦ N (step T105; YES), the control unit 4 determines the i-th preference item stored in the ID 80 of the read content information. The display text is substituted for variable X (step T106). In addition, the control unit 4 substitutes the display text of the jth preference item candidate for the variable Y (step T107).

  Next, the control unit 4 compares the values of the variable X and the variable Y, and X = Y, that is, the display text of the i-th preference item and the display text of the j-th preference item candidate in ID80 are If it is determined that they do not match (step T108; NO), the value of the variable j is incremented by 1 (step T109), and the value of the variable j is compared with the value of the variable M. If j> M is not satisfied, that is, if there is a preference item candidate that has not yet been compared with the i-th preference item of ID80 (step T110; NO), the processing returns to step T107. When j> M, that is, when the comparison between the i-th preference item of ID80 and all preference item candidates is completed (step T110; YES), the control unit 4 increments the variable i by 1 (step T111). ), The process returns to T105, and the next preference item and the preference item candidate are sequentially compared.

  On the other hand, if it is determined in step T108 that X = Y, that is, the display text for the i-th preference item in ID80 matches the display text for the j-th preference item candidate (step T108; YES). The control unit 4 determines whether or not the i th preference item in the ID 80 is set (selected) as a user preference item, that is, whether or not the default value of the i th preference item is “1”. to decide. If it is determined that the i-th preference item in ID80 is not set (selected) as a user-preferred item, that is, the default value of the i-th preference item is “0” (step T112; NO), the control unit 4 shifts to the processing of T109. When it is determined that the i-th preference item in ID 80 is set (selected) as a user's preference item, that is, the default value of the i-th preference item is “1” (step T112; YES), the control unit In step 4, “true” is substituted for variable ret (step T113), and the process proceeds to T12 in FIG.

  If i> N in step T105 (step T105; NO), the control unit 4 determines that the comparison between all preference items and preference item candidates has been completed, and proceeds to the processing of step T12 in FIG. .

  In step T12 in FIG. 14, the control unit 4 determines whether or not the variable ret = true, and determines that the variable ret = true is not satisfied (step T12; NO), the process proceeds to step T9 in FIG. To do. If it is determined that the variable ret = true (step T12; YES), the control unit 4 executes a preference item addition process (step T13).

  FIG. 16 is a flowchart showing the preference item addition process executed by the control unit 4 in step T13 of FIG.

  In the preference item addition process, the control unit 4 first assigns 1 to the variable i and 1 to the variable j as initial values (step T201).

  Next, the control unit 4 retrieves and reads out the content information including ID80 from the content information of the nth delivery provider stored in the storage unit 1f (step T202), and the variable N is included in the preference information of ID80. The number of preference items is substituted (step T203).

  Next, the control unit 4 refers to the similar preference item table 112, changes the player information (value of the variable B) stored in the variable B, and the similar preference item (value of the variable B) associated with the player information ( The total number of preference item candidates) is counted and substituted into the variable M as the number of preference item candidates (step T204).

  Next, the control unit 4 compares the value of the variable i with the value of the variable N. If i ≦ N (step T205; YES), the control unit 4 determines the i-th preference item stored in the ID 80 of the read content information. The display text is substituted for variable X (step T206). In addition, the control unit 4 substitutes the display text of the jth preference item candidate for the variable Y (step T207).

  Next, the control unit 4 compares the values of the variable X and the variable Y, and X = Y, that is, the display text for the i-th preference item and the display text for the j-th preference item candidate in ID80 are obtained. If it is determined that they match (step T208; YES), the default value of the i-th preference item stored in ID80 is set to "1" (step T209), and the process proceeds to step T210. If X = Y is not satisfied, that is, if it is determined that the display text for the i-th preference item in ID80 does not match the display text for the j-th preference item candidate (step T208; NO), the control unit 4 performs step The process proceeds to T210.

  In step T210, the control unit 4 increments the value of the variable j by 1 (step T210), and compares the value of the variable j with the value of the variable M. If j> M is not satisfied, that is, if there is a preference item candidate that has not yet been compared with the i-th preference item of ID80 (step T211; NO), the control unit 4 returns to the process of step T207. When j> M, that is, when the comparison between the i-th preference item of ID80 and all preference item candidates is completed (step T211; YES), the control unit 4 increments the variable i by 1 (step T212). ), The process returns to step T205, and the next preference item and the preference item candidate are sequentially compared.

If it is determined in step T205 that i> N (step T205; NO), the control unit 4 proceeds to the process of step T9 in FIG.
By the above-described preference information update process of the nth distributor, the preference information included in the content information of the ith distributor corresponds to the type of the playback device 1h installed in the car navigation unit 1 before the change. When the item is set as an item that the user likes, an item corresponding to the type of the player 1h after the change is automatically added to the item that the user likes. If there is an item for which the default value is set to “1” in step T209, the control unit 4 in the uplink information stored in the storage unit 1f before the process proceeds to step T9 in FIG. The setting value of the corresponding item in the preference information may also be changed to “1”. Thereby, the item corresponding to the type of the player 1h after the change can be automatically set as an item that the user likes without involving the user's operation. Alternatively, the control unit 4 displays the preference item setting screen G1 on the display unit 1e based on the preference information added to the item that the item corresponding to the type of the player 1h after the change likes. Preference information in which the type of the player 1h after the change is added to the preference information in the uplink information stored in the storage unit 1f in response to pressing of the “OK” button B1 by the input unit 1d. You may make it update to.

  In step T9 of FIG. 13, the control unit 4 increments the variable n by 1 (step T9), and returns to the process of step T7. If it is determined in step T7 that n> m (step T7; NO), the control unit 4 ends this process.

  When the vehicle-mounted device 10 enters the mutual communication area Z of the roadside apparatus 20 after the above-described player change check process B, communication between the center device 30 and the vehicle-mounted device 10 shown in FIG. Uplink information including preference information added as an item preferred by the type of the machine 1h is transmitted to the center device 30. In the center apparatus 30, content information to be distributed to the vehicle-mounted device 10 is determined based on the updated uplink information, and is distributed to the vehicle-mounted device 10. That is, if there is content information of a category corresponding to the type of the player 1h after the change, it is distributed to the vehicle-mounted device 10.

  As described above, according to the information distribution system 100 in the second embodiment, the control unit 4 of the vehicle-mounted device 10 stores the car navigation unit model number information before the change of the car navigation unit 1 in the storage unit 3c or the external memory device ED. To determine whether or not the type of the player 1h has been changed based on the car navigation unit model number information of the navigation device before the change and the car navigation unit model information acquired from the current car navigation unit 1. When it is done, an item corresponding to the type of the player 1h after the change in the preference information is added to the item preferred by the user.

  Therefore, when there is a change in the type of the player 1h mounted on the vehicle-mounted device 10, an item corresponding to the type of the player 1h after the change in the preference information is automatically added to the item preferred by the user. Therefore, it becomes possible to receive the content information corresponding to the type of the changed player 1h without the user's effort.

  Also, a preference item setting screen G1 in which items corresponding to the type of the player 1h after the change are set in advance to items that the user likes is displayed, and included in the uplink information in response to the user pressing the “OK” button B1. By updating the preference information to be transmitted, it is possible to update the preference information for transmission after confirming that the user has changed the preference information.

  In the second embodiment, the case has been described in which the preference information of the uplink information is updated using the preference information of ID80 included in the content information stored in the storage unit 1f. The preference information update process of the n-th distributor may be executed using the preference information of the uplink information instead of the preference information of ID80 included in the content information, and the preference information of the uplink information may be directly updated. .

  In addition, when the second embodiment is applied and the external speaker SP connected to the player 1h is changed, for example, when a subwoofer or the like is newly connected as the external speaker SP, You may make it update preference information automatically according to the change of a speaker. Hereinafter, an example in which the preference information is updated according to the change of the speaker will be described.

  When changing the speaker, the user gives an instruction to set the speaker by operating the input unit 1d from the menu screen. When an instruction for speaker setting is input, the control unit 4 displays a speaker setting screen or the like on the display unit 1e, and allows the user to input various setting information such as selection of the speaker configuration (number of channels, etc.) after the change. . Then, the setting information input from the speaker configuration setting screen including the changed speaker configuration information is stored in the storage unit 1f. At this time, the speaker configuration information before the change is saved in another area of the storage unit 1f.

  When the setting of the speaker configuration is completed, the control unit 4 executes a speaker configuration change check process shown in FIG.

  In the speaker configuration change check process, the control unit 4 first reads information on the speaker configuration before the change stored in the storage unit 1f and substitutes it into the variable A (step T301). Next, the changed speaker configuration information is read and substituted into the variable B (step T302).

  Next, the control unit 4 compares the value of the variable A with the variable B, and determines that A = B, that is, if there is no change in the speaker configuration (step T303; NO), the process is terminated.

  If it is determined that the value of the variable A is different from the value of the variable B, that is, the speaker configuration has been changed (step T303; YES), the control unit 4 determines the surround configuration based on the value of the variable B (for example, the number of channels). It is determined whether or not it has been changed. If it is determined that the surround configuration has not been changed (step T304; NO), the control unit 4 ends this process. When it is determined that the surround configuration has been changed (step T304; YES), the control unit 4 substitutes the number of distributors contracted for the variable m (step T305), and substitutes 1 for the variable n (step T306). Next, the control unit 4 compares the value of the variable m with the value of the variable n, and when n ≦ m (step T307; YES), executes the preference information update process of the nth distributor (step S307). T308).

  The preference information update process of the nth delivery company in step T308 and the subroutine in this process are the same as those described with reference to FIGS. Here, in executing these processes, for example, the variable A includes “speaker configuration name before change (for example, monaural, stereo, etc.) + Current player information based on the information of the speaker configuration before change. Is substituted with text information. For example, when the speaker configuration information before the change is 2 channels and the type of the player 1h is DVD, “stereo DVD” is substituted for the variable A. In variable B, “surround + current player information” is substituted with text information. For example, “surround DVD” is substituted for variable B. Thereby, when the item related to the speaker configuration before the change in the preference information is selected, the item related to the speaker configuration after the change is automatically selected. For example, if “stereo DVD” is selected as the preference information before the change, “surround DVD” is automatically selected after the change.

  When the preference information update process for the n-th distribution provider is completed, the control unit 4 increments the variable n by 1 (step T309), and returns to step T307. If it is determined in step T307 that n> m is satisfied (step T307; NO), the control unit 4 ends this process.

As mentioned above, although 1st and 2nd embodiment which concerns on this invention has been described, the said embodiment is a suitable example of this invention, and is not limited to this.
For example, in the first embodiment, the storage unit 34 includes the similar preference item table 112 illustrated in FIG. 12, and the items corresponding to the previous player 1 h are items that the similar preference items are considered as preference items. It may be determined whether or not the item is selected, and an item corresponding to the current player 1h may be specified. As a result, even if there are different items indicating the same contents in the same distributor, it is possible to add items corresponding to the current player 1h as preference items.
