[0007] For example, this case corresponds to a case where a player is connected to a network but wants to play music using a terminal (for example, a mobile phone) without a disc media playback function.

[0008] In such a case, even if the music is purchased through disk media, the music is distributed. If you obtain a service cover, you must purchase it again, creating the problem of double purchase.

[0009] Therefore, a music distribution service has been proposed that allows users who purchase disc media to enjoy the playback of purchased content data anytime, anywhere without forcing the disadvantage of purchasing the same content data twice. Speak.

In this music distribution service, identification information is added to a disk medium such as a CD, and a user who purchases the disk medium registers the identification information in the management server. Using this registered identification information, a content list is generated that indicates which music the user already has.

[0011] Then, when receiving this music distribution service, the content data of the music held by the user is reproduced or downloaded free of charge based on the generated content list (for example, Patent Document 1). ).

The DAC 210 controls the control unit to output the received content data to the speaker 213.

Based on the control of 201, the digital force is also converted into analog. In FIG. 2, an amplifier is omitted between the DAC 210 and the speaker 213 in order to simplify the description.

The drawing LSI 208 is a circuit that converts the content data content list into drawing data in order to display the content data content list on the display monitor 212 based on the control of the control unit 201.

[0069] The user recognition unit 200 has a function of recognizing a user. As shown in FIG. 3, the user recognition unit 200 includes an antenna unit 301, a data reading unit 302, a user information storage unit 303, a determination unit 304, and an output unit 305.

The IC unit 300 is, for example, an IC card that stores unique user information for identifying a user who possesses the IC unit 300. The IC unit 300 may be an IC card, for example, an IC tag.

The antenna unit 301 transmits radio waves to the IC unit 300. The IC unit 300 generates electric power from the received radio wave, stores it, and transmits user information to the antenna unit 301.

Data reading unit 302 reads user information received by antenna unit 301 and passes the read user information to determination unit 304. The user information storage unit 303 stores user information for identifying the user in advance.

The determination unit 304 determines whether or not the user information received from the antenna unit 301 matches the user information stored in the user information storage unit 303. The output unit 305 outputs the determination result of the determination unit 304.

Note that the user recognition unit 200 is configured to recognize a user using an IC card, but is not limited thereto, and is configured to recognize a user based on an ID, a user name, or the like input manually. Alternatively, the user may be recognized by other methods such as fingerprint recognition and face image recognition. In addition, a single user recognition unit 200 may be provided in each seat in the rickshaw.

[0075] The input unit 211 is, for example, a remote control touch switch, a voice input microphone, or the like that accepts input from the user. In the input unit 211, content data to be reproduced is selected from the content list.

The memory 209 is used for temporarily storing data and performing a program for controlling the entire in-vehicle device 100 in order to perform streaming.

Further, the display monitor 212, the speaker 213, and the input unit 211 are not limited to this and may be provided outside the in-vehicle device 100.

On the other hand, the content server 120 includes a communication unit 203, a control unit 204, a storage unit 205, a profile integration unit 206, and a content list generation unit 207. The control unit 204 manages processing of the entire content server apparatus.

[0079] Communication unit 203 communicates with in-vehicle device 100 via a network. The storage unit 205 stores content data, a content list, and a user profile.

HDD.

[0080] The storage unit 205 stores, for example, music data as content data. Further, as shown in Fig. 4, the storage unit 205 stores a list including the title, artist, album name, and playback time of the music. The content list 400 in the initial state is stored in advance.

Further, as shown in FIG. 5, the storage unit 205 stores a profile 500 indicating the user's possession status (the mark is owned, the mark is not owned) in association with the song title. is doing. The profile data may be user preference information. The content data is not limited to music data, but may be video data.

Next, the operation of the content list generation system in the first exemplary embodiment will be described using the flowchart of FIG.

[0083] First, it is assumed that three family members (user A, user B, and user C) get on a car. When each user brings the IC unit 300 possessed in advance to the antenna unit 301 of the user recognition unit 200, the user recognition unit 200 recognizes the user (step S601). The user information of the user recognized by the user recognition unit 200 is transmitted from the in-vehicle device 100 to the content server 120 via the network 110 by the communication unit 202 of the in-vehicle device 100 (step S602).

[0085] The user information transmitted from the in-vehicle device 100 to the content server 120 is received by the communication unit 203 of the content server 120 (step S603). When receiving the user information, the control unit 204 of the content server 120 determines whether or not there is a plurality of received user information (step S604).

[0086] In the determination process S604, when there are a plurality of pieces of received user information, the profile integration unit 206 reads a plurality of profiles corresponding to each of the user information from the storage unit 205, and the degree of commonality of the plurality of read profiles Based on the above, profile integration is performed (step S605).

[0087] In the integration of the profiles, if a song is owned by, for example, three of user A, user B, and user C, the highest priority 1 is given to the song. The Here, the priority is the priority of the title display order of each piece of music displayed as a content list.

[0088] Similarly, two users, User A and User B own! /, Or two users, User A and User, or User B and User C. Is owned by the second highest priority 2.

[0089] If only user A owns! /, Or only user B owns! /, Or only user C owns, the third highest priority 3 is Is granted. If no user owns it, then no priority is given. If there is no priority, do not display it as a content list.

[0090] In this way, the profile integration unit 206 assigns priorities in association with the titles of the music pieces, as shown in FIG. 7, based on the common degree of the plurality of profiles corresponding to each piece of user information. Then, multiple profiles are integrated to generate an integrated profile 700. The integrated profile 700 is generated by associating the title and priority of each song.

[0091] Further, when the integrated profile 700 is generated, the content list generating unit 207, based on the integrated profile file 700, obtains the title of each song associated with the priority level as an artist. The contents list 800 is generated as shown in FIG. 8 by sequentially reading from the storage unit 205 together with the title, album name, and playback time (step S606).

The content list data generated by the content list generating unit 207 is transmitted from the content server 120 to the in-vehicle device 100 via the network 110 by the communication unit 203 of the content sano 120 (step S607).

The content list data transmitted from the content server 120 to the in-vehicle device 100 is received by the communication unit 202 of the in-vehicle device 100 (step S608). When the content list data is received, the control unit 201 of the in-vehicle device 100 displays the received content list on the display monitor 212 as shown in FIG. 9 (step S609). An identification mark indicating the priority is displayed on the content list. Also, express the priority with the color and font of the text.

[0094] Then, when the user selects content data to be played back in the displayed content list using input unit 211, the selected content data is distributed from content server 120 (step S610).

On the other hand, in the determination processing step S604, when the received user information is singular, the content list generation unit 207 assigns the title of each song to an artist, based on the profile corresponding to the user information. Along with the album name and playback time, the content list is read out in order from the storage unit 205 (steps S604 and S606). Similarly, the processing from step S607 to step S610 is executed.

Accordingly, it is possible to provide a content list generation system, a content server, and an in-vehicle device that generate an adaptive content list in consideration of the environment of a user who receives content data distribution.

[Embodiment 2]

Hereinafter, the content list generation system, content server, and in-vehicle device according to Embodiment 2 of the present invention will be described with reference to the drawings, omitting the same parts as those in the first embodiment.

[0098] As shown in FIG. 10, the storage unit 205 of the content server 120 stores a profile 1000 indicating the user's possession status (the mark is owned, the mark is owned, and the mark is owned). No Memorize it in association with ittle.

As shown in FIG. 11, the user recognition unit 200 of the in-vehicle device 100 further includes a main user information input unit 1 100 and a user information generation unit 1101. The main user information input unit 1100 is, for example, an input button, a touch switch, a voice input microphone, or the like that receives input of main user information. Further, the user at the driver's seat may be the main user in association with the user location information.

[0100] The user information generation unit 1101 generates user information in which the main user information input from the main user information input unit 1100 is added to the user information output from the determination unit 304. The output unit 305 outputs the generation result of the user information generation unit 1101.

[0101] Next, the operation of the content list generation system in Embodiment 2 will be described using the flowchart of FIG.

[0102] Two family members (user A and user B) get on a car. Here, it is assumed that the user A who is the driver is the main user. First, user A inputs that he is the main user in the main user information input unit 1110.

[0103] Next, when user A and user B bring IC unit 300 possessed in advance closer to antenna unit 301 of user recognition unit 200, user recognition unit 200 recognizes the user (step S12).

01).

It should be noted that after the user recognition unit 200 recognizes all users, a screen that prompts the user to input main user information for selecting the main user from the list of recognized users is displayed on the display monitor 21.

The configuration displayed in 2 is also ヽ.

[0105] The user information of the user recognized by the user recognition unit 200 is the communication unit 22 of the in-vehicle device 100.

0 is transmitted from the in-vehicle device 100 to the content server 120 via the network 110 (step S 1202).

[0106] The user information transmitted from the in-vehicle device 100 to the content server 120 is received by the communication unit 203 of the content server 120 (step S1203). When receiving the user information, the control unit 204 of the content server 120 determines whether or not there is a plurality of received user information (step S 1204).

[0107] In the determination processing step S1204, if there are a plurality of pieces of received user information, The file integration unit 206 integrates the profiles based on the profile corresponding to the user information to which the main user information is added among the plurality of user information (step S12 05).

[0108] In this profile integration, if user A owns a piece of music, the highest priority 1 is given. Similarly, if only user B is owned, the second highest priority is given. If no user owns it, then no priority is given.

As described above, the profile integration unit 206 sets the priority for each music piece as shown in FIG. 13 based on the profile corresponding to the user information to which the main user information is added among the plurality of user information. It is given in association with the title of, and multiple profiles are integrated to generate an integrated profile 1300. The integrated profile 1300 is generated by associating the title and priority of each song.

[0110] Furthermore, when the integrated profile 1300 is generated, the content list generation unit 207 displays the title of each song associated with the priority along with the artist, album name, and playback time based on the integrated profile 1300.
