The communication means 20 provides an interface for communicating with each in-vehicle terminal.

[Control means]
The control means 30 performs various controls in the server device S. The control means 30 includes a CPU and a memory (both not shown). The CPU implements various functions by executing programs stored in memory.

In this embodiment, the CPU executes the hitchhiking content program, so that the control means 30 functions as the first acquisition section 100, setting section 200, second acquisition section 300, update section 400, and distribution section 500. do.

(First acquisition part)
The first acquisition unit 100 corresponds to the song identification information of a song performed in karaoke using the karaoke performance function and the singing voice accompanying the karaoke singing by the certain user from a certain in-vehicle terminal operated by a certain user. The vehicle acquires the singing voice data, the travel route including the destination set using the car navigation function, and the terminal identification information of the certain in-vehicle terminal.

A certain user who wishes to use hitchhiking content gets into a vehicle and then operates a certain in-vehicle terminal to start a content application.

A certain user selects a destination to travel to by vehicle using a navigation function provided by a content application. A certain in-vehicle terminal sets an optimal travel route from a current position (starting point) acquired using a GPS function to a selected destination. A certain in-vehicle terminal stores the set travel route in a storage means (not shown) provided in the certain in-vehicle terminal. The travel route includes location information indicating the location of the destination. As the vehicle moves, a certain in-vehicle terminal performs navigation to a destination based on a set travel route. Optimum travel route setting and navigation can utilize techniques implemented in known navigation systems.

While traveling to a destination, a certain user operates a certain in-vehicle terminal to select a song that he/she wishes to sing at karaoke. A certain in-vehicle terminal transmits the song identification information of the selected song to the server device S in association with its own terminal identification information.

The server device S reads karaoke performance data corresponding to the received song identification information from the storage means 10 and transmits it to a certain in-vehicle terminal. A certain in-vehicle terminal uses a karaoke performance function provided by a content application to perform a karaoke performance based on received karaoke performance data. The performance sound of a karaoke performance is emitted from a sound emitting means of a certain vehicle-mounted terminal (or a sound emitting means such as a speaker included in the vehicle). A certain user performs karaoke singing using a sound collecting means of a certain in-vehicle terminal (or a sound collecting means such as a headset attached to the in-vehicle terminal). A certain in-vehicle terminal stores singing voice data corresponding to the singing voice accompanying a certain user's karaoke singing in a storage means (not shown) provided in the certain in-vehicle terminal in association with song identification information.

After that, a certain user operates a certain in-vehicle terminal and selects "hitchhiking mode" on the display means. The hitchhiking mode is a mode for distributing singing voice data to one in-vehicle terminal (described later). When the hitchhiking mode is selected, a certain in-vehicle terminal transmits the song identification information, singing voice data, and travel route stored in a storage means (not shown) to the server device S in association with the terminal identification information. .

The first acquisition unit 100 stores music identification information, singing audio data, travel route, and terminal identification information received from a certain in-vehicle terminal in the singing audio table of the storage means 10.

(setting section)
The setting unit 200 sets the acquired terminal identification information of a certain in-vehicle terminal as the terminal identification information of one in-vehicle terminal.

One in-vehicle terminal is a terminal that receives distribution of karaoke performance data and singing voice data corresponding to music identification information received from a certain in-vehicle terminal.

When the setting unit 200 acquires music identification information, singing voice data, travel route, and terminal identification information from the in-vehicle terminal where the first acquisition unit 100 is located, the setting unit 200 stores the terminal identification information in the terminal ID table of the storage unit 10. By storing it in the terminal, it is set as the terminal identification information of one in-vehicle terminal. In this way, when starting to use the hitchhiking content, the terminal identification information of one in-vehicle terminal becomes the terminal identification information of a certain in-vehicle terminal.

(Second acquisition part)
The second acquisition unit 300 acquires location information indicating the current position of the one in-vehicle terminal and terminal identification information of the one in-vehicle terminal from one in-vehicle terminal, and acquires the car navigation function from another in-vehicle terminal. The vehicle's travel route including the destination set using , location information indicating the current position of the other in-vehicle terminal, and terminal identification information of the other in-vehicle terminal are acquired.

The in-vehicle terminal that has started the content application uses the GPS function to obtain its current location at predetermined intervals. The predetermined interval is set in advance to be one interval, for example every 5 seconds.

One in-vehicle terminal transmits the position information acquired using the GPS function to the server device S in association with the terminal identification information. The second acquisition unit 300 stores the position information and terminal identification information received from one in-vehicle terminal in the position information table of the storage means 10 together with the travel route. The second acquisition unit 300 updates the position information stored in the position information table every time it acquires position information from one in-vehicle terminal. Note that the travel route stored at the start of use of the hitchhiking content is the travel route acquired from a certain in-vehicle terminal (the travel route stored in the singing voice table). On the other hand, when the terminal identification information of one in-vehicle terminal is updated (described later), the movement route to be stored becomes the movement route acquired from another updated in-vehicle terminal.

The other in-vehicle terminals are terminals other than the in-vehicle terminal that transmitted the song identification information, the singing voice data, the moving route, and the terminal identification information to the server device S. Other in-vehicle terminals are operated by other users.

After getting into the vehicle, other users who wish to use the hitchhiking content operate another in-vehicle terminal to start the content app.

Other users use the navigation function provided by the content application to select a destination to travel to by vehicle. The other in-vehicle terminal sets an optimal travel route from the current position (starting point) acquired using the GPS function to the selected destination. The other in-vehicle terminal stores the set travel route in a storage means (not shown) included in the other in-vehicle terminal.

After that, another user operates another in-vehicle terminal and selects "singing audio data reception mode" on the display means. The singing voice data reception mode is a mode for receiving distribution of singing voice data acquired from a certain in-vehicle terminal. When the singing voice data reception mode is selected, the other in-vehicle terminal uses the moving route stored in the storage means (not shown) and the location information indicating the current location acquired using the GPS function as the terminal identification information. and is sent to the linking server device S.

The second acquisition unit 300 stores the travel route, position information, and terminal identification information received from other in-vehicle terminals in the position information table of the storage means 10. The second acquisition unit 300 updates the position information stored in the position information table every time it acquires position information from another vehicle-mounted terminal.

(Update Department)
The update unit 400 is configured to update another in-vehicle terminal that is located within a predetermined range with respect to the current location of one in-vehicle terminal, and in which at least a portion of the first route and the second route overlap. The terminal identification information of the terminal is updated as the terminal identification information of one in-vehicle terminal.

The predetermined range is a reference for determining the positional relationship between one vehicle-mounted terminal and another vehicle-mounted terminal. For the predetermined range, one standard is set in advance, for example, "a radius of 100 m centered on the current position of one in-vehicle terminal." The first route is a route from the current position of one in-vehicle terminal to a destination included in the travel route acquired from one in-vehicle terminal. The second route is a route from the current position of another vehicle-mounted terminal to a destination included in the travel route acquired from the other vehicle-mounted terminal.

When the second acquisition unit 300 acquires position information from one in-vehicle terminal, the updating unit 400 updates the current position indicated by the position information and the position information of the other in-vehicle terminal stored in the storage unit 10. The current position is compared with the current position to determine whether there is another in-vehicle terminal located within a predetermined range of the current position of one in-vehicle terminal.

When it is determined that there is another in-vehicle terminal (hereinafter referred to as another in-vehicle terminal Mx) located within a predetermined range with respect to the current position of one in-vehicle terminal, the updating unit 400 The travel route acquired from the vehicle-mounted terminal is read, and a route (ie, a first route) from the current position of one vehicle-mounted terminal to the destination included in the travel route is calculated. Additionally, the updating unit 400 reads out the travel route acquired from the other vehicle-mounted terminal Mx stored in the position information table, and selects a route that is included in the travel route acquired from the other vehicle-mounted terminal Mx based on the current position of the other vehicle-mounted terminal Mx. A route (ie, a second route) to the destination is calculated. The updating unit 400 determines whether at least a portion of the calculated first route and the second route overlap.

If it is determined that at least part of the first route and the second route overlap, the updating unit 400 updates the terminal identification information stored in the terminal ID table of the storage means 10 as the terminal identification information of the one in-vehicle terminal. is updated to the terminal identification information of another in-vehicle terminal Mx. In other words, the terminal ID table of the storage means 10 contains one piece of terminal information that is located within a predetermined range with respect to the current position of one in-vehicle terminal, and that at least part of the first route and the second route are connected. Stores duplicate terminal identification information of other in-vehicle terminals Mx.

Note that the updating unit 400 may perform the update when the overlap between the first route and the second route is a predetermined distance or more. The predetermined distance is a standard for determining whether to perform an update. The predetermined distance is set to one value in advance, such as "1 km", for example.

(Distribution Department)
When the distribution unit 500 determines that a vehicle equipped with one in-vehicle terminal has arrived at a destination included in the travel route acquired from a certain in-vehicle terminal, the distribution unit 500 transmits the information acquired from the in-vehicle terminal to the one in-vehicle terminal. Karaoke performance data and singing voice data corresponding to song identification information are distributed.

The distribution unit 500 determines, at a predetermined timing, whether a vehicle equipped with one in-vehicle terminal has arrived at a destination included in a travel route acquired from a certain in-vehicle terminal. For example, each time the second acquisition unit 300 acquires location information from one in-vehicle terminal, the distribution unit 500 transmits the current location indicated by the location information and the location of the destination included in the travel route acquired from the one in-vehicle terminal. Find the distance between. If the determined distance is less than a certain value (for example, less than 500 m), the distribution unit 500 determines that the vehicle equipped with one on-vehicle terminal has arrived at a destination included in the travel route acquired from one on-vehicle terminal. .

In this case, the distribution unit 500 reads out karaoke performance data corresponding to the song identification information from the storage unit 10 based on the song identification information acquired from a certain in-vehicle terminal. Further, the distribution unit 500 reads singing voice data stored in the singing voice table. The distribution unit 500 distributes the read karaoke performance data and singing voice data to one in-vehicle terminal.

The first in-vehicle terminal plays back the received karaoke performance data using the karaoke function of the content application, and causes the sound emitting device to emit the karaoke performance sound. Further, the first in-vehicle terminal plays back the received singing voice data using the karaoke function of the content application, and causes a certain user's singing voice to be emitted from the sound emitting means. A user riding in a vehicle equipped with an in-vehicle terminal can listen to a karaoke performance of a song selected by the user along with the singing voice of the user.

Note that there is a possibility that a vehicle equipped with the first in-vehicle terminal may not pass a vehicle equipped with an in-vehicle terminal running a content application until it reaches its destination. That is, the terminal identification information of one in-vehicle terminal may remain the terminal identification information of a certain in-vehicle terminal that was initially set (that is, the in-vehicle terminal that transmitted the singing voice data).

In this case, the distribution unit 500 executes the same process as described above, and when distributing karaoke performance data and singing voice data to a certain in-vehicle terminal, an error message (for example, "Unfortunately, hitchhiking failed ”) may also be delivered together with message data for presenting.

A certain in-vehicle terminal can display an error message on a display means or emit a sound of an error message from a sound emitting means based on the received message data.

Alternatively, the distribution unit 500 may stop distributing the karaoke performance data and singing voice data when the terminal identification information of one in-vehicle terminal is the terminal identification information of a certain in-vehicle terminal that was initially set.

==About the operation of the server device==
Next, a specific example of the operation of the server device S in this embodiment will be described with reference to FIGS. 3 to 6. FIG. 3 is a flowchart showing the operation of the server device S. 4 to 6 are diagrams schematically showing a travel route R1 of the vehicle C1, a travel route R2 of the vehicle C2, and a travel route R3 of the vehicle C3. As shown in FIG. 1, vehicle C1 is equipped with an on-vehicle terminal M1 operated by a driver D1, vehicle C2 is equipped with an on-vehicle terminal M2 operated by a driver D2, and vehicle C3 is equipped with an on-board terminal M1 operated by a driver D1. An in-vehicle terminal M3 operated by a driver D3 is installed. Content applications are installed on the in-vehicle terminals M1 to M3.

The first acquisition unit 100 corresponds to the song ID of the song performed in karaoke using the karaoke performance function from a certain in-vehicle terminal operated by a certain user, and the singing voice accompanying the karaoke singing of the certain user. Obtain the singing voice data, the vehicle's travel route including the destination set using the car navigation function, and the terminal ID of the certain in-vehicle terminal (music ID, singing voice data, travel route, and terminal from a certain in-vehicle terminal) Obtain ID. Step 10).

The setting unit 200 sets the terminal ID of a certain in-vehicle terminal acquired in step 10 as the terminal ID of one in-vehicle terminal (setting the terminal ID of one in-vehicle terminal. Step 11).

The second acquisition unit 300 acquires, from one in-vehicle terminal, location information indicating the current position of the one in-vehicle terminal and the terminal ID of the one in-vehicle terminal (location information and terminal ID from one in-vehicle terminal). Obtain step 12).

The second acquisition unit 300 also acquires, from other in-vehicle terminals, the travel route of the vehicle including the destination set using the car navigation function, location information indicating the current position of the other in-vehicle terminal, and other in-vehicle terminals. (Obtain the moving route, location information, and terminal ID from other in-vehicle terminals. Step 13).

The update unit 400 determines whether there is another in-vehicle terminal located within a predetermined range with respect to the current position of one in-vehicle terminal. Step 14).

If it is determined that there is another in-vehicle terminal located within a predetermined range with respect to the current position of one in-vehicle terminal (Y in step 15), the update unit 400 updates the current position of one in-vehicle terminal to a certain in-vehicle terminal. A first route to the destination included in the travel route acquired from the terminal, and a second route from the current position of the other in-vehicle terminal to the destination included in the travel route acquired from the other in-vehicle terminal. Calculate (calculate the first route and the second route. Step 16).

The updating unit 400 determines whether at least a portion of the calculated first route and the second route overlap (determine whether the first route and the second route overlap. Step 17).

If at least part of the first route and the second route obtained in step 16 overlap (Y in step 18), the updating unit 400 updates the terminal ID of the other in-vehicle terminal with the one in-vehicle terminal. (Update the terminal ID of the first in-vehicle terminal. Step 19).

When it is determined that the vehicle equipped with the first in-vehicle terminal has arrived at a destination included in the travel route acquired from the in-vehicle terminal (Y in step 20), the distribution unit 500 transmits the message to the first in-vehicle terminal. , distributes karaoke performance data and singing voice data corresponding to the song ID acquired from a certain in-vehicle terminal (distributing karaoke performance data and singing voice data to one in-vehicle terminal; step 21).

Specifically, after getting into the vehicle C1, the driver D1 who wishes to use the hitchhiking content operates the in-vehicle terminal M1 to start the content application. The driver D1 corresponds to a "certain user," and the in-vehicle terminal M1 corresponds to a "certain in-vehicle terminal."

The driver D1 uses the navigation function provided by the content application to select a destination DST1 to which the vehicle C1 will travel. The in-vehicle terminal M1 sets an optimal travel route R1 from the departure point OR1 acquired using the GPS function to the destination DST1 selected by the driver D1 (see FIG. 4). The in-vehicle terminal M1 stores the set travel route R1 in a storage means (not shown) included in the in-vehicle terminal M1. After that, driver D1 starts driving vehicle C1.

While traveling to the destination DST1, the driver D1 operates the in-vehicle terminal M1 to select a song X that he desires to sing at karaoke. The in-vehicle terminal M1 performs a karaoke performance of the song X using a karaoke performance function provided by the content application. The driver D1 performs karaoke singing using a headset attached to the in-vehicle terminal M1. The in-vehicle terminal M1 associates the singing voice data SD corresponding to the singing voice accompanying the karaoke singing of the driver D1 with the song ID***X of the song X, and stores it in a storage means (not shown) provided in the in-vehicle terminal M1. Make me remember.

Thereafter, the driver D1 operates the in-vehicle terminal M1 and selects "hitchhiking mode" on the display means. The in-vehicle terminal M1 associates the song ID***X, singing voice data SD, and travel route R1 stored in a storage means (not shown) with the terminal ID***M1 and transmits them to the server device S. .

The first acquisition unit 100 stores the song ID****X, singing voice data SD, movement route R1, and terminal ID***M1 received from the in-vehicle terminal M1 in the singing voice table of the storage means 10.

When the setting unit 200 acquires the song ID****X, the singing voice data SD, the moving route R1, and the terminal ID****M1 from the in-vehicle terminal M1, the setting unit 200 stores the terminal ID****M1 in the storage means 10. By storing it in the terminal ID table, it is set as the terminal ID of one vehicle-mounted terminal m.

The in-vehicle terminal M1 corresponding to one in-vehicle terminal m transmits position information indicating the current position CL1 to the server device S in association with the terminal ID***M1. The second acquisition unit 300 stores the location information and terminal ID***M1 received from the in-vehicle terminal M1 in the location information table of the storage means 10 together with the travel route R1.

On the other hand, after getting into the vehicle C2, the driver D2 who wishes to use the hitchhiking content operates the in-vehicle terminal M2 to start the content application. The driver D2 corresponds to "another user", and the in-vehicle terminal M2 corresponds to "another in-vehicle terminal".

The driver D2 uses the navigation function provided by the content application to select a destination DST2 to which the vehicle C2 will travel. The in-vehicle terminal M2 sets an optimal travel route R2 from the departure point OR2 acquired using the GPS function to the selected destination DST2 (see FIG. 4). The in-vehicle terminal M2 stores the set travel route R2 in a storage means (not shown) included in the in-vehicle terminal M2.

Thereafter, the driver D2 operates the in-vehicle terminal M2 and selects the "singing audio data reception mode" on the display means. The in-vehicle terminal M2 sends location information indicating the travel route R2 stored in a storage means (not shown) and the current position CL2 acquired using the GPS function to the terminal ID***M2 and the linking server device S. Send.

The second acquisition unit 300 stores the travel route R2, position information, and terminal ID***M2 received from the in-vehicle terminal M2 in the position information table of the storage means 10.

Similarly, after getting into the vehicle C3, the driver D3 who wishes to use the hitchhiking content operates the in-vehicle terminal M3 to start the content application. Driver D3 corresponds to "another user", and in-vehicle terminal M3 corresponds to "another in-vehicle terminal".

The driver D3 uses the navigation function provided by the content application to select a destination DST3 to which the vehicle C3 will travel. The in-vehicle terminal M3 sets an optimal travel route R3 from the departure point OR3 acquired using the GPS function to the selected destination DST3 (see FIG. 4). The in-vehicle terminal M3 stores the set travel route R3 in a storage means (not shown) included in the in-vehicle terminal M3.

Thereafter, the driver D3 operates the in-vehicle terminal M3 and selects the "singing audio data reception mode" on the display means. The in-vehicle terminal M3 associates the moving route R3 stored in a storage means (not shown) and the location information indicating the current position CL3 acquired using the GPS function with the terminal ID***M3 and links it to the server device S. Send.

The second acquisition unit 300 stores the travel route R3, position information, and terminal ID***M3 received from the in-vehicle terminal M3 in the position information table of the storage means 10.

Here, when the second acquisition unit 300 acquires new position information from the in-vehicle terminal M1, the updating unit 400 updates the current position CL1 indicated by the new position information and the in-vehicle terminal M2 stored in the storage means 10. The current position CL2 indicated by the position information of the in-vehicle terminal M3 is compared with the current position CL3 indicated by the position information of the in-vehicle terminal M3, and the current position CL2 of the in-vehicle terminal M1 is within a predetermined range PR (for example, the current position CL1 of the in-vehicle terminal M1 is centered). It is determined whether at least one of the vehicle-mounted terminal M2 and the vehicle-mounted terminal M3 exists within a radius of 100 m).

In this example, as shown in FIG. 5, the vehicle-mounted terminal M2 is within a predetermined range PR with respect to the current position CL1 of the vehicle-mounted terminal M1 (that is, the current position CL2 of the vehicle-mounted terminal M2 is within the predetermined range PR). In this case, the update unit 400 reads the travel route R1 acquired from the in-vehicle terminal M1 stored in the singing voice table, and updates the route r1 from the current position CL1 of the in-vehicle terminal M1 to the destination DST1 included in the travel route R1. calculate. The update unit 400 also reads the travel route R2 acquired from the in-vehicle terminal M2 stored in the position information table, and calculates the route r2 from the current position CL2 of the in-vehicle terminal M2 to the destination DST2 included in the travel route R2. do. The updating unit 400 determines whether the calculated route r1 and at least a portion of the route r2 overlap.

In this example, as shown in FIG. 5, at least a portion of route r1 and route r2 overlap. The updating unit 400 updates the terminal ID***M1 stored as the terminal ID of one vehicle-mounted terminal m in the terminal ID table of the storage means 10 to the terminal ID***M2 of the vehicle-mounted terminal M2.

Thereafter, when the second acquisition unit 300 acquires new position information from the in-vehicle terminal M2, the distribution unit 500 transmits the current position CL2 indicated by the position information and the purpose included in the travel route R1 acquired from the in-vehicle terminal M1. Find the distance to the position of the ground DTS1. In this example, it is assumed that the calculated distance is a certain value or more. In this case, the distribution unit 500 determines that the vehicle C2 equipped with the on-vehicle terminal M2 has not arrived at the destination DST1 included in the travel route R1 acquired from the on-vehicle terminal M1.
