  The operation of the in-vehicle content search device 1 configured as described above will be described with reference to FIG.

  First, when a destination is set via the input device 3 (S31), a route search is performed by the route search means 9 (S32).

  Next, it is judged by the content search means 13 whether or not the memory location data of the set destination is stored in the memory location storage means 10 (S33).

  If it is determined in step S33 that the memory location data of the destination is stored, the content search means 13 determines whether or not content information is included in the memory location data (S34).

  On the other hand, when it is determined in step S33 that the destination memory point data is not stored, the operation of the in-vehicle content search device 1 ends.

  If it is determined in step S34 that the content information is included in the destination memory point data, the content search means 13 determines whether the reproduction type of the content information is normal reproduction. (S35).

  On the other hand, when it is determined in step S34 that the content information is not included in the memory point data of the destination, the operation of the in-vehicle content search device 1 ends.

  If it is determined in step S35 that the playback type of the content information included in the memory location data is not normal playback, the content search rule included in the content information is acquired by the content search means 13 (S36).

  Next, from the content stored in the content storage unit 12, the content in accordance with the content search rule is searched by the content search unit 13, and a reproduction list representing the searched content list is generated by the content search unit 13. (S37).

  The content is reproduced by the content reproduction means 14 according to the generated reproduction list (S38), and the operation of the in-vehicle content search device 1 ends.

  On the other hand, when it is determined in step S35 that the reproduction type of the content information included in the memory point data is normal reproduction, the source type included in the content information is acquired by the content search means 13 (S39).

  Next, the source played back by the content playback means 14 is switched according to the source type (S40).

  Next, the content included in the switched source is sequentially played back by the content playback means 14 (S41), and the operation of the in-vehicle content search device 1 is finished.

  Since the in-vehicle content search apparatus 1 according to the first embodiment of the present invention searches for content according to the content search rule associated with the route search destination, the user can select the route search destination. It is possible to reproduce the content according to the destination without setting the search rule only by setting.

(Second Embodiment)
In the in-vehicle content search device 1 according to the first embodiment of the present invention, a plurality of destinations for route search may be set via the input device 3.

  Hereinafter, the operation of the in-vehicle content search device 1 configured as described above will be described as a second embodiment of the present invention with reference to FIG.

  First, when a destination is set via the input device 3 (S53), a temporary reproduction list is generated (S54). This temporary reproduction list is generated by the in-vehicle content search device 1 operating in the same manner as steps S32 to S37 in FIG.

  Next, the required time to the destination is calculated by the route search means 9 (S55).

  Next, the content search means 13 sequentially adds from the first provisional reproduction list to the reproduction list (S56), and each time it is added, the total reproduction time of the content represented by the reproduction list is equal to or longer than the required time to the destination. It is determined whether or not there is (S57). Here, if it is determined that the total content playback time is not equal to or longer than the required time to the destination, the next content is added (S56), and if determined to be equal to or longer than the required time to the destination, playback is performed. List generation is complete.

  For example, as shown in FIG. 5, when the required time to the destination is T hours, and the reproduction times of the contents # 1 to #n represented by the temporary reproduction list are t1 to tn hours, the reproduction list is content search means. 13 is generated as follows. First, content # 1 is added to the reproduction list. Since the total reproduction time t1 of the content represented by the reproduction list at this time is not equal to or longer than the required time T, the next content # 2 is added to the reproduction list. Similarly, content # 7 is sequentially added to the reproduction list. At this time, the total of the reproduction times of the contents represented by the reproduction list from t1 to t7 is equal to or longer than the required time T, and the generation of the reproduction list is completed.

  Here, when a plurality of destinations are set, the in-vehicle content search device 1 operates in the same manner as steps S54 to S57 for each destination, and a reproduction list corresponding to the destination is generated.

  The content represented in the reproduction list generated in this way is reproduced by the content reproduction means 14 in the order of the set destinations, and the operation of the in-vehicle content search device 1 is ended.

  If the route is changed due to a change in road conditions, the route search means 9 calculates the required time to the destination again. When the calculated required time is changed from the required time before the route change, the in-vehicle content search device 1 operates in the same manner as steps S56 to S57, and the reproduction list is updated.

  According to such an in-vehicle content search device 1 of the second embodiment of the present invention, content whose total playback time is equal to or longer than the required time to each destination from the content searched according to each destination. The user can select multiple destinations for route search, and can continue to play content according to each destination until reaching the final destination without setting search rules. Can do.

(Third embodiment)
In the in-vehicle content search device 1 according to the second embodiment of the present invention, a route search destination may be added via the input device 3.

  Hereinafter, the operation of the in-vehicle content search device 1 configured as described above will be described as a third embodiment of the present invention with reference to FIG.

  In FIG. 6, it is assumed that the destination 1 and the destination 3 are already set, and the reproduction list 64 corresponding to the destination 1 and the reproduction list 66 corresponding to the destination 3 have already been generated.

  First, when the destination 2 is added via the input device 3 between the destination 1 and the destination 3, the route search means 9 searches for the route from the destination 1 to the destination 2, and the destination. A route search from 2 to the destination 3 is performed, and a required time T2 from the destination 1 to the destination 2 and a required time T3 from the destination 2 to the destination 3 are calculated.

  Next, the content search unit 13 searches the content according to the content search rule associated with the destination 2 and reconstructs each playlist corresponding to each destination.

  For example, the playlist 64 corresponding to the destination 1 does not need to be updated because the insertion position of the destination 2 is behind the destination 1 and the required time T1 is not changed.

  The playlist 65 corresponding to the destination 2 needs to be newly generated. Here, since the playback time of the playlist 64 corresponding to the destination 1 exceeds the required time T1 to the destination 1 by t1, the content whose total playback time is equal to or more than T2-t1 hours is the destination. The content search unit 13 selects the content searched according to the location 2 to generate the reproduction list 65 corresponding to the destination 2.

  The playlist 66 corresponding to the destination 3 needs to be updated because the insertion position of the destination 2 is before the destination 3 and the required time T3 is changed. Here, since the playback time of the playlist 65 corresponding to the destination 2 exceeds the time T2-t1 by t2, the content whose playback time is equal to or more than T3-t2 hours depends on the destination 3. Then, the content search means 13 selects again from the searched content, and the reproduction list 66 corresponding to the destination 3 is updated.

  According to the in-vehicle content search device 1 of the third embodiment of the present invention as described above, when a destination for route search is added, it corresponds to a destination set after the added destination. Since the user selects the content again, the user can simply add the route search destination and do not need to set a search rule. Can continue to play.

  As described above, the in-vehicle content search device of the present invention can search for content according to the destination of the route search without setting a search rule each time the destination of the route search is set. It is useful as an in-vehicle content search device that searches for content to be played back by the in-vehicle content playback device.
