Further, the subsequent communication regarding the creation application of the content reproduction list is not performed to the terminal or the device which does not recognize the existence. Thus, the in-vehicle space can be defined as a predetermined wireless communication range, and, for example, preventing transmission of content to a terminal or device unrelated to the operation of the present embodiment outside the vehicle can be prevented. it can. In addition, in the case of the system of FIG. 2, as described above, the control unit 601 of the server 106 creates the content reproduction list only for the portable wireless terminals 103, 104, and 105 riding on the same vehicle 101. . Such a configuration can prevent the leakage of content.

Then, in S101, an apparatus (hereinafter, referred to as a parent apparatus) having a role of creating a content reproduction list is determined. In the case of the system of FIG. 1, for example, it is determined by negotiation between a plurality of portable wireless terminals via the close proximity wireless transfer unit 541. Here, the reference of the negotiation may be, for example, a portable wireless terminal holding the largest number of contents as the parent device. In the case of the system of FIG. 2, the server 106 is determined as a parent device. Further, in the case of the system of FIG. 3, the content reproduction apparatus 102 is determined as a parent device. Hereinafter, regardless of which system the main device is, it will be generically described as "master device".

In S102, the control unit of the parent device acquires, from each of the portable wireless terminals 103, 104, and 105, content information that is tag information attached to the content. The control unit of the parent device, for example, requests content information from each portable wireless terminal, and acquires content information as a response to the request. The content information includes lyrics, melody, tempo, wavelength analysis data, release date, artist name, instrument type, tie-up information, song name or album name, country of production, label type, and information of shooting location. The content information may further include information generated based on the above information.

In S103, the control unit of the parent device acquires information on future elements and information on current elements from the portable wireless terminal or the content reproduction apparatus 102. Here, information on future elements and information on current elements will be described.

The information on the future element is information on the destination in the drive stroke of the vehicle 101. For example, position information of the destination of the vehicle 101, topography in the vicinity of the destination, building, area, time, day, night, weather, season, etc. It is information. These can be acquired from the navigation function of the mobile wireless terminals 103, 104, 105 or the vehicle 101. Alternatively, the portable radio terminals 103, 104, 105 or the content reproduction apparatus 102 may acquire the above-mentioned pieces of information via the Internet line.

The information on the current element is information on the traveling condition of the current position in the drive stroke of the vehicle 101, and for example, information on the current position of the vehicle 101, topography near the current position, buildings, area, time, day, night, weather, season, etc. It is. The current position information of the vehicle 101 can be acquired from the vehicle 101 or the content reproduction apparatus 102. In addition, information such as topography, buildings, areas, time, day and night, weather, seasons, and the like near the current location can be acquired from the GPS signal or the Internet by the portable radio terminals 103, 104, and 105 or the content reproduction device 102, for example.

In S104, the control unit of the parent device determines the contribution of each of the current element and the future element to the creation of the content reproduction list based on the information on the current element and the information on the future element acquired in S103. Here, the degree of contribution is an index as to how much influence it has on the selection of songs when creating the content reproduction list. For example, the degree of contribution may be the degree of attainment to the destination, and the master sets the contribution of each of the present element and the future element based on how far the current position of the vehicle 101 is from the destination. Decide. In S105, the control unit of the parent device creates a content reproduction list for reproduction of a predetermined number of contents based on the degree of contribution determined in S104.

FIG. 7 is a diagram for explaining creation of a content reproduction list in the present embodiment. In the present embodiment, it is possible to change the standard of music selection for creating the reproduction list of the content in accordance with the traveling condition at the current position of the vehicle 101. As shown in FIG. 7, when the vehicle 101 is at a position immediately after the start point, the content reproduction list created at that time considers the present element at 90% and the future element at 10%. And the list is selected. For example, nine songs selected for the current location "Kanagawa" (information on the current element) are selected, and one song selected for the destination "Niigata" (information on the future element) is selected. When this reaches the middle point of the vehicle 101, the current element is considered at 50% and the future element at a ratio of 50%, for example, five songs named after the current location "Saitama" are selected, and the destination The selected list is created with five songs named after "Niigata". In addition, when the vehicle 101 reaches near the destination, the current element is considered at 10% and the future element at 90%, for example, one song related to "Gunma" at the current position is selected and the purpose is A selected list of nine songs named after "Niigata" on the ground is created.

For example, the following relationship is used between the information on the current element or the future element and the selected song. For example, the similarity between the content information of each content acquired in S102 and the current element is scored. In scoring, the more items matched, the higher the score. A matching item is, for example, a scene in analogy to the lyrics (eg, where the words “summer” and “summer” in the lyrics match the current season, where the artist's birthplace and present location match) Night) and current time information match, and so on. Further, if the current vehicle speed is a constant high speed and the tune is equal to or higher than a predetermined tempo, it may be determined that the two match. Such scoring will be done for future elements as well.

The above-described scoring is performed. For example, in the case of selecting two songs for the current element, two songs are randomly selected from a predetermined number of songs (for example, ten songs) having high scores for the current element. In addition, in the case of selecting eight songs for the element in the future, eight songs are randomly selected from the top ten songs having scores for the element in the future. Then, the selected song is excluded from the order of scores, and in the case of song selection in the creation of the next list, the selected song is excluded from the top 10 songs in a state of excluding the already selected song.

Methods other than the above may be used as to what kind of relationship to use. For example, when the application is executed in S101, the setting may be made on the user interface screen displayed on the display unit 441 of the content reproduction apparatus 102. For example, setting items such as “current position and destination”, “time”, and “season” may be displayed as selectable conditions for scoring based on the similarity. For example, when the selection of the setting item of “season” is not accepted, the item of “season” can be excluded in the above judgment of the match.

The playback order of the selected song for each of the current element and the future element is determined randomly. As a result, it is possible to give the occupant a sense of anticipation as to what song will be reproduced next. However, the order of reproduction may be determined based on a predetermined standard.

In S106, the control unit of the parent device transmits the reproduction instruction signal indicating the reproduction of the content to the portable wireless terminal storing the content to be reproduced in the storage unit 530 in accordance with the reproduction order of the content reproduction list created in S105. Do. In the case of the system of FIG. 1, the portable wireless terminal 103 as the parent device transmits a reproduction instruction signal to the corresponding portable wireless terminal. Further, in the case of the system of FIG. 2, the server 106, which is a parent device, transmits a reproduction instruction signal to the corresponding portable wireless terminal. Further, in the case of the system of FIG. 3, the content reproduction apparatus 102 transmits a reproduction instruction signal to the corresponding portable wireless terminal.

At S107, the control unit of the portable wireless terminal that has received the reproduction instruction signal transmits the content to the content reproduction apparatus 102, and instructs reproduction of the content. The content reproduction apparatus 102 reproduces the received content. When the reproduction of the received content is completed, the content reproduction apparatus 102 transmits an end notification to the parent device. Also, the content reproduction apparatus 102 deletes the content whose reproduction has ended from the content reproduction apparatus 102.

Although the content reproduction apparatus 102 has been described above as reproducing content, the content may be reproduced by a corresponding portable wireless terminal. Such a configuration can prevent the movement of the content and reduce the possibility of the content leaking. In addition, the control unit of the portable wireless terminal having received the reproduction instruction signal temporarily displays on the display unit 550 that the reproduction instruction signal has been received, and the content reproduction apparatus 102 receives the content in response to the confirmation operation by the user. You may send it. For example, the display mode of the display can be used as a conversation source by changing the display mode of each song, such as the "hit" display.

In S108, the control unit of the parent device determines whether the reproduced content is the final content of the content reproduction list. If it is determined that the content is the final content, the process proceeds to S109. If it is determined that the content is not the final content, the processing from S106 is repeated.

In step S109, the control unit of the parent device determines whether it is necessary to create the next content reproduction list. This determination may be made, for example, when it is determined that the creation of the next content reproduction list is not necessary when the current position approaches a distance within a predetermined threshold from the destination, for example, in the vicinity of the destination. If it is determined in S109 that it is necessary to create the next content reproduction list, the processing from S103 is repeated. On the other hand, when it is determined that it is not necessary to create the next content reproduction list, the processing of FIG. 8 is ended.

As described above, in the present embodiment, the content reproduction list is created according to the degree of contribution of each of the current element and the future element. Hereinafter, as an example, a case will be described in which one vehicle 101 is boarded by three people, leaving Minato-ku, Tokyo, and heading for a circuit facility in an additional amusement park in Mogi-cho, Tochigi. In the following example, it is assumed that the system of FIG. 1 is used.

First, when three people get on the vehicle, each executes a content reproduction list creation application of the portable wireless terminals 103, 104, 105. Then, the three portable wireless terminals negotiate with each other, and a parent portable wireless terminal is determined (S101).

The parent portable wireless terminal acquires content information from the portable wireless terminals 103, 104, and 105 possessed by each of the three occupants. In this example, the content is the music content, and the parent portable wireless terminal is the portable wireless terminal 103 in FIG. That is, the portable wireless terminal 103 acquires content information from the other portable wireless terminals 104 and 105, and stores the content information in the content storage unit 532 together with the content information held by itself (S102).

Next, the portable wireless terminal 103 acquires information on the future element and information on the current element from the content reproduction apparatus 102 and the portable wireless terminal 103 (S103). Here, it is assumed that the portable wireless terminal 103 determines that the vehicle 101 is currently traveling in, for example, a port area where the drive stroke is 10%, from the acquired information on the current element. In that case, the portable wireless terminal 103 determines that the contribution ratio of the current element is 90%, and based on the information on the current element, the tower which is a famous radio tower, the rain which is the current weather, and the spring which is the season. Content having an associated element is selected for 90% of the number of songs of a predetermined number of songs. For example, if the predetermined number is 10 songs, 9 songs are selected. Furthermore, the portable radio terminal 103 determines that the contribution ratio of the future element including the information on Motegi town which is the destination is 10%, and based on the information on the future element, 10% of the number of tunes of a predetermined number of tunes. ,select. Here, if the predetermined number is 10 songs, the remaining 1 song is selected. The portable wireless terminal 103 creates a content reproduction list from the selected nine songs and one song (S104, S105). For example, a method as described above is used as to which song to select and the playback order of the selected song.

The portable radio terminal 103 transmits a reproduction instruction signal to the portable radio terminal in which each content is stored, in accordance with the reproduction order of the created content reproduction list (S106). The portable wireless terminal having received the music reproduction instruction signal transmits the content to the content reproduction apparatus 102 to reproduce the content (S107).

When the reproduction of the content by the content reproduction list of 10 pieces of music is finished (S108: Yes), the portable wireless terminal 103 creates a new content reproduction list with the point traveling at that time as an element at present (S109: Yes -S105). For example, when it is determined from the acquired information of the present element that the current position travels Kasama City, Ibaraki Prefecture, the portable radio terminal 103 determines that the contribution rate of the current element is 20%, and as the information about the current element We select two songs related to grilled dishes and chestnuts that are special products of Kasama City. Furthermore, the portable radio terminal 103 determines that the contribution rate of the element in the future is 80%, and selects eight songs based on information on the element in the future, for example, a special product of Mogi City, Ibaraki Prefecture. Then, the portable wireless terminal 103 creates a content reproduction list from the selected two songs and eight songs.

With the above configuration, when the destination is close, more content related to the destination is reproduced. As a result, the drive can be produced by the content. In the above example, the content to be reproduced is stored in the three portable wireless terminals 103, 104, and 105. As a result, more reproduction options occur than the number of contents held by the portable wireless terminal by one person, and it is less likely to get bored than when the same contents are reproduced. Also, the content to be reproduced is the content held by any one of the three persons. Therefore, for example, it is possible to continue providing a source of the topic even in a long drive, such as giving a quiz to determine who was holding the content, and explaining the content.

In the present embodiment, the content reproduction list is indicated by a predetermined number of contents (for example, 10 songs), but may be constituted by a predetermined total time such as "30 minutes" instead of the number of contents. For example, if 10 songs are selected by the above-described method, and the total playback time exceeds 30 minutes, the selected song may be deleted or reselected. For example, if the total amount falls within 30 minutes by deleting any of the selected songs, the deletion may be performed. At this time, the song selected based on the information on the current element has a higher priority than the song selected on the basis of the information on the future element, and any of the songs selected based on the information on the future element You may delete it. Further, which priority is higher can be set in advance on the user interface screen or the like, and may be deleted from the music selected based on the information of lower priority. In addition, after deletion, a song may be reselected such that the reproduction time falls within a predetermined 30 minutes.

Second Embodiment
Next, a configuration for setting an evaluation value of content after content reproduction will be described. The differences from the first embodiment will be described below. In this embodiment, the content reproduction apparatus 102 as a parent device, the portable wireless terminals 103, 104, and 105, and the server 106 have a function of setting the evaluation value of the content. In the present embodiment, when the evaluation value of the content is low after the reproduction of the content, the content can be excluded from selection or hard to be selected when the content reproduction list is generated next time.

9A and 9B are flowcharts showing processing of content reproduction control in the present embodiment. Each process of FIG. 9A and FIG. 9B is executed in any of the content reproduction apparatus 102, the portable wireless terminals 103, 104, 105, and the server 106. Since S201 to S204 are the same as the descriptions in S101 to S104 of FIG. 8, the description will be omitted.

In step S205, the control unit of the parent device starts specifying a generation target of a content reproduction list. Here, the control unit of the parent device determines the order in which the processing of S206 to S209 is performed on the plurality of pieces of content information acquired in S202.

In S206, the control unit of the parent device determines whether or not the target content information is to be a creation target of a content reproduction list, in the order determined in S205. This determination is performed, for example, in the following procedure. In the present embodiment, the content information includes flag information indicating an evaluation value of the content. The flag information is represented by, for example, a numerical value, and the control unit of the parent device determines whether the content information is to be created as a reproduction list of content based on whether the flag information satisfies a predetermined condition or not. Determine if For example, if the flag information is equal to or greater than a predetermined threshold value, it is determined that the flag information satisfies a predetermined condition, and the content information is to be created for the reproduction list of the content. On the other hand, if it is less than the predetermined threshold, the flag information does not satisfy the predetermined condition, and it is determined that the content information is not a creation target of the reproduction list of the content. If it is determined in S206 that the target content information is not the creation target of the content reproduction list, the process proceeds to S207, and the control unit of the parent device identifies the next content information in the order determined in S205. Repeat the process. On the other hand, when it is determined in S206 that the target content information is to be the creation target of the content reproduction list, the process proceeds to S208, and the control unit of the parent device specifies the content information as the creation target of the content reproduction list.

After S208, in S209, the control unit of the parent device determines whether or not the determination processing of S206 has ended for all the content information acquired in S202. If it is determined that the determination process of S206 has not been completed for all content information, the process proceeds to S207, the next content information is specified, and the process from S206 is repeated. On the other hand, if it is determined that the determination process of S206 has been completed for all the content information, the process proceeds to S210.

In S210, the control unit of the parent device creates a content reproduction list in the content information identified in S208. The creation of the content reproduction list is as described in the first embodiment. Since S211 and S212 are the same as the description in S106 and S107 of FIG. 8, the description is omitted.

In S213, the control unit of the parent device determines whether or not normal reproduction has been performed for the content to which the reproduction instruction signal has been transmitted in S211. For example, the control unit of the parent device determines that normal reproduction has not been performed if there is an operation such as volume reduction, fast forward, or skip in the middle of reproduction, and proceeds to S214. In S214, the control unit of the parent device adds a value corresponding to each operation to the content information as flag information. For example, in an operation such as skipping to stop listening to the entire song, a negative value having a larger absolute value may be added to the operation of reducing the volume. Also, when an operation such as repeat is performed to repeat the music, a positive value may be added. If it is determined in S213 that the normal reproduction of the content has been performed, or after S214, the process proceeds to S215.

Since S215 and S216 are the same as the description in S108 and S109 of FIG. 8, the description will be omitted.

As described above, according to the present embodiment, it is possible to regard content having a low evaluation value as having low preference and to make it difficult to be reproduced in the next content reproduction list. Further, in the present embodiment, it has been described that flag information is added to the operation of lowering the volume and the operation of fast forward and skip. However, flag information may be added based on other elements. For example, a negative value may be added as flag information based on a negative voice in a car, a negative face image captured by an in-vehicle camera provided in a pillar portion of the car, or the like. Also, a positive value may be added as flag information based on a positive voice or a positive face image. Alternatively, the value of the flag information to be added may be comprehensively determined in combination with each operation such as skipping and the voice information and face information described above.
