On the other hand, if the song ID specified in step S123 is different from the song ID of the currently reproduced song data (step S124: Yes), the process proceeds to step S125. In this case, the processing after step S125 is performed to switch the music data currently being reproduced. Specifically, the control unit 11 first transmits the music ID identified in step S123 to the server device 2 via the communication unit 13 (step S125). That is, the control unit 11 transmits the music ID corresponding to the music data to the server device 2 in order to request the server device 2 to transmit the music data to be reproduced. And in the server apparatus 2, the communication part 23 receives music ID transmitted from the terminal device 1 (step S221), and the control part 21 reads the music data corresponding to the said music ID from the memory | storage part 22, and reads. The music data is transmitted to the terminal device 1 via the communication unit 23 (step S222).

Next, in the terminal device 1, the communication unit 13 receives the music data transmitted from the server device 2 (step S126). And the control part 11 reproduces | regenerates the music data which the communication part 13 received (step S127). That is, the control unit 11 switches music data to be reproduced.

The present invention is not limited to application to music (music), but can be applied to various contents. For example, the present invention can also be applied to moving image content.

[2] Second Embodiment Next, a second embodiment of the present invention will be described. The second embodiment is a music distribution system including a distributor terminal 3 of a distributor (content provider) that provides music data in addition to a user terminal device 1 and a server device 2.

[System configuration]
FIG. 5 shows a configuration of a music distribution system 50 according to the second embodiment. As illustrated, the music distribution system 50 includes a terminal device 1, a server device 2, and a distributor terminal 3. The configuration of the terminal device 1 is the same as that of the first embodiment.

The distributor terminal 3 is a terminal used when the distributor registers the music distribution conditions with the server device 2, and is configured by a normal personal computer (PC) or the like. That is, the distributor terminal 3 includes a CPU, a ROM, a RAM, an input device, a display device, and the like (not shown), and communicates with the server device 2 via a network.

The configuration of the server device 2 is basically the same as that of the first embodiment. However, as illustrated, the server apparatus 2 of the second embodiment includes various databases (hereinafter, “database” is referred to as “DB”) in the storage unit 22. Specifically, the storage unit 22 includes a road DB 221, a traffic statistics information DB 222, a traffic information DB 223, a charging information DB 224, a distribution management DB 225, a music DB 226, and a music metadata DB 227.

The road DB 221 stores road data (map data). The road data includes data of nodes and links constituting the road network. Nodes correspond to intersections and links correspond to roads.

The traffic statistics information DB 222 stores traffic statistics information. The traffic statistical information is generated based on travel information (positioning data) acquired from a large number of vehicles, and is information in which a user ID, a travel time, a travel time, a traveling direction, and the like are associated with each road.

The traffic information DB 223 stores traffic information. The traffic volume information is information that is generated based on the traffic statistics information and indicates the traffic volume within a certain time for each road. Specifically, the traffic information includes the number of traveling vehicles, the number of users, the average travel time, etc. within a certain time for each road.

The billing information DB 224 stores a delivery fee for each road as billing information. The distribution fee indicates a fee charged by the operator of the server device 2 to the music distributor when one music is provided to the user on a certain road. The distribution fee is determined based on the traffic volume of the road, and the details will be described later.

The distribution management DB 225 stores information related to music distribution on each road, specifically, distribution condition information and distribution record information. The distribution condition information is information that is set for each road and indicates a condition for distributing music. For example, the distribution condition information includes conditions such as an ID of a music to be distributed, a day of the week on which the music is distributed, a time zone, and weather for a certain road. On the other hand, distribution result information is information which shows the distribution history of the music with respect to the terminal device 1 which actually moved the road for every road. For example, the distribution result information includes the date and time of distribution of music on a certain road, the number of times, the ID or user ID of the terminal device 1 as the distribution destination, and the like.

The music DB 226 stores music data, that is, music data of the music itself. The music data is stored in association with a music ID which is music identification information. The music data is in a data format such as Wave, MP3, m4a, for example.

The music metadata DB 227 stores metadata related to music. Specifically, the metadata includes the artist name, genre, album name, track number, track title, disc number, release year, etc. of the music.

In the above configuration, the communication unit 23 of the server device 2 is an example of a transmission unit and a reception unit of the present invention, and the control unit 21 is an example of a storage unit, a registration unit, and a distribution unit of the present invention.

[Overview of control]
Next, an outline of control will be described. In this embodiment, first, the operator of the server apparatus 2 determines the amount (distribution fee) to be charged to the distributor when distributing music for each road. At this time, the server device 2 collects vehicle travel information (positioning data) from a large number of terminal devices 1 and calculates the traffic volume for each road. And the delivery charge for every road is determined by the calculation method in consideration of the traffic volume. The determined distribution fee is stored in the billing information DB 224.

Next, the distributor operates the distributor terminal 3 to register the music to be distributed to the user and the metadata of the music. The music and the music metadata are stored in the music DB 226 and the music metadata DB 227 in the server device 2, respectively.

Next, the distributor operates the distributor terminal 3 to register the distribution conditions in the server device 2. Specifically, the distributor sets music to be distributed to the user for each road. In addition, conditions such as the day of the week, the time zone, and the weather for distributing the music are set as necessary. The set distribution conditions are stored in the distribution management DB 225 of the server 2.

Thus, when the preparation for distributing the music is completed, the music set for the road is distributed every time the terminal device 1 travels on the road. Therefore, the user can listen to the music set for each road when traveling on the road. Here, “distribution” means so-called streaming distribution, and the terminal device 1 reproduces music data while partially receiving music data from the server device 2. Unlike the so-called download distribution, the music data does not remain in the storage unit of the terminal device 1 when the reproduction ends.

[Processing flow]
Hereinafter, each process will be described in detail.

(Road traffic information generation processing)
First, the road traffic information generation process will be described. The road traffic information generation process is a process for generating road traffic information based on travel information (positioning data) collected from a plurality of terminal devices 1. The road traffic information generation process includes a positioning data recording process, a data communication process, and a traffic information generation process.

FIG. 6 is a flowchart of positioning data recording processing, data communication processing, and traffic information generation processing. These processes are executed by the terminal device 1 and the server device 2. Specifically, the control unit 11 of the terminal device 1 and the control unit 21 of the server device 2 are each implemented by executing a prepared program.

First, the terminal device 1 performs positioning data recording processing. The terminal device 1 generates positioning data including the current position based on the outputs of the GPS receiver 14 and the self-supporting positioning device 15, and stores it in the internal storage unit 12 (step S131). Specifically, the terminal device 1 stores the latitude / longitude of the current position of the vehicle, the traveling direction, and the current time as positioning data at regular time intervals. Next, the terminal device 1 determines whether or not a recording stop condition is satisfied (step S132). The recording stop condition is, for example, when the vehicle stops. The terminal device 1 continues to record the positioning data until the recording stop condition is satisfied. When the recording stop condition is satisfied (step S132: Yes), the positioning data recording process is terminated.

Next, the terminal device 1 and the server device 2 perform data communication processing. First, the terminal device 1 reads the positioning data stored in the storage unit 12 in the positioning data recording process, and transmits it to the server device 2 together with the user ID of the terminal device 1 (step S133). The server device 2 receives the positioning data from the terminal device 1 and temporarily stores it in the storage unit 22 (step S231). This completes the data communication process.

Next, the server device 2 performs traffic information generation processing. First, the server device 2 performs link matching using the temporarily stored positioning data and road data (step S232). That is, the server device 2 refers to the road DB 221 and identifies the road and the traveling direction indicated by the positioning data based on the latitude / longitude and the traveling direction included in the positioning data. The server device 2 performs this process on a large number of positioning data acquired from the plurality of terminal devices 1. Then, the server device 2 calculates the user ID, travel time, travel time, and traveling direction of the terminal device 1 for each road based on the processing result of step S232, and stores these in the traffic statistics information DB 222 as traffic statistics information. Save (step S233). This completes the traffic information generation process. By the traffic information generation process, traffic statistics information for each road is obtained based on the positioning data from the terminal device 1 mounted on many vehicles. Specifically, the traffic volume (number of traveling vehicles), traveling direction, traveling speed, etc. for each road at a certain time can be obtained.

(Delivery fee calculation processing)
Next, the distribution fee calculation process will be described. The distribution fee calculation process is a process for determining the distribution fee of the music for each road based on the traffic volume. The distribution fee calculation process includes a traffic volume calculation process and a distribution fee calculation process.

FIG. 7 is a flowchart of traffic volume calculation processing and distribution fee calculation processing. These processes are performed by the server device 2. Specifically, it is realized by the control unit 21 of the server device 2 executing a program prepared in advance.

First, the server device 2 reads the traffic statistics information from the traffic statistics information DB 222 and calculates the traffic volume for each fixed period for each road (step S241). Specifically, the server device 2 calculates the number of traveling, the number of users, the average travel time (average speed), and the like as the traffic volume. And the server apparatus 2 preserve | saves the calculated traffic volume in traffic volume information DB223 (step S242). This ends the traffic volume calculation process.

Next, the server device 2 performs a distribution fee calculation process. The server device 2 reads the traffic volume from the traffic volume information DB 223 and calculates a delivery fee for each road (step S243). The server device 2 determines the distribution fee for each road link and traveling direction in consideration of the traffic volume and the expected value of the number of users to be distributed. Specifically, the server apparatus 2 calculates a distribution fee according to the following equation (1).

The delivery fee “Ci” is set for each road (link) and for each traveling direction. The basic discount rate “a” is applied to each distributor, each link, and each area for various reasons. When a = 1, there is no discount, when a <1, the delivery fee is reduced, and when a> 1, the delivery fee is increased. For example, a> 1 is set when the distribution charge of an area is higher than the standard distribution charge, and a <1 is set when the distribution charge is reduced.

As the traffic volume “Ti” per unit time, the traffic volume for each road stored in the traffic volume information DB 223 is used. The charge “V” per unit traffic is a unit charge per traffic, and is set to “X yen / 100 units”, for example. The fixed cost “Bc” corresponds to a basic cost for operating the music distribution system, and is basically set to a fixed amount.

The success fee “α” is an amount corresponding to an incentive paid from the distributor to the operator of the server device 2 based on the actual distribution of the music. The success fee “α” is set, for example, for a fixed amount or for each song when the actual delivery performance (number of songs delivered, number of users or terminals targeted for delivery) exceeds a predetermined number It can be an amount.

The server apparatus 2 stores the distribution fee calculated in this way in the charging information DB for each road and for each traveling direction (step S244). This completes the distribution fee calculation process. The distribution fee calculation process determines the distribution fee of the music for each road and for each traveling direction, and the charge information DB 224 is prepared.

(Delivery order processing)
Next, the distribution order process will be described. The distribution order process is a process in which a distributor sets music to be distributed, roads to be distributed, and distribution conditions. The distribution order process includes a distribution music registration process and a distribution target designation process.

FIG. 6 is a flowchart of the distribution music registration process. This processing is executed by the distributor terminal 3 and the server device 2. Specifically, this is realized by the CPU of the distributor terminal 3 and the control unit 21 of the server device 2 executing programs prepared in advance.

First, when the distributor operates the distributor terminal 3 to select a music to be distributed, the distributor terminal 3 receives the selection and acquires music data from an internal database or the like (step S311). Next, the distributor terminal 3 acquires the metadata of the selected music from an internal database or the like (step S312). Then, the distributor terminal 3 transmits the acquired music data and metadata to the server device 2 (step S313).

The server device 2 receives the music data and the metadata from the distributor terminal 3 (step S251) and stores them in the music data DB 226 and the music metadata DB 227, respectively (step S252). This completes the distribution music registration process. The music composition data and metadata of the music to be distributed are registered in the database of the server device 2 by the distribution music registration process.

FIG. 9 is a flowchart of the distribution target designation process. This process is also executed by the distributor terminal 3 and the server device 2.

First, the distributor operates the distributor terminal 3 to make an inquiry for designating a distribution target (step S321). For example, the distributor accesses the online client system on the Web at the distributor terminal 3 and makes an inquiry. At the time of the inquiry, in addition to the music ID indicating the music to be distributed, the distributor provides search conditions such as a distribution fee, a position (area or road link), a traveling direction, and the expected number of distributions (number of users to be distributed). specify. In other words, the distributor sends a query including conditions that are considered to be suitable when distributing a certain piece of music.

The server device 2 refers to the charging information DB 224, the map data DB 221, the distribution management DB 225, etc., and searches for roads (links) that match the search conditions included in the inquiry, and a list of roads that match the inquiry as the search results. Is transmitted to the distributor terminal 3 (step S262). For example, when a distributor specifies a distribution fee, a list of roads where music can be distributed at the specified distribution fee is provided. Further, when the distribution company specifies the expected number of distributions, a list of roads where the specified number of distributions can be expected is provided to the distribution company based on the distribution results stored in the distribution management DB 225. Therefore, the distributor can search for a road to be distributed from various viewpoints.

When the distributor specifies a road to be distributed by looking at the list received, the distributor terminal 3 transmits the specification of the road to the server device 2 (step S323). The server device 2 receives the designation of the road to be distributed from the distributor terminal 3 (step S263) and stores it in the distribution management DB 225 (step S264). This completes the delivery target designation process.

Thus, the music to be distributed for each road and for each traveling direction is set by the distribution target designation process. Note that the distributor may specify the day of the week, the time zone, the weather, the road condition, and the like as the distribution conditions when specifying the distribution target. These are stored in the distribution management DB 225 as distribution conditions for the music. For example, the distributor can set distribution conditions for music distribution on a specific road, such as only on Saturdays and Sundays, only in the daytime, only on sunny days, and when there is no traffic jam.

(Music distribution processing)
Next, the music distribution process will be described. The music distribution process is a process in which the server device 2 distributes the music set for the road in response to a request from the terminal device 1 when the terminal device 1 is traveling on the road.

FIG. 10 is a flowchart of the music distribution process. This process is executed by the terminal device 1 and the server device 2. Specifically, the control unit 11 of the terminal device 1 and the control unit 21 of the server device 2 are realized by executing a program prepared in advance.

First, the terminal device 1 acquires positioning data indicating the current position of the vehicle, and transmits a music distribution request including the positioning data to the server device 2 (step S141). The server device 2 receives the music distribution request from the terminal device 1, and refers to the road DB 221 based on the positioning data to determine the road (link) on which the vehicle is currently traveling (step S271). Next, the server device 2 refers to the distribution management DB 225 to determine the music set for the road on which the vehicle is traveling (step S272), and stores the music data and metadata as the music DB 226 and the music, respectively. Obtained from the metadata DB 227 (step S273), and distributes them to the terminal device 1 (step S274).

The terminal device 1 receives the music data and metadata from the server device 2 and reproduces the music (step S142). At this time, the terminal device 1 displays a song name, an artist name, and the like based on the received metadata. Next, the terminal device 1 determines whether the reproduction has been stopped (step S143). The case where the reproduction stops is, for example, a case where the user of the terminal device 1 stops the music reproduction. When the reproduction is stopped (step S143: Yes), the music distribution process ends. On the other hand, when the reproduction is not stopped (step S143: No), the process returns to step S141. And the terminal device 1 transmits positioning data newly to a server apparatus, for example, when passing the intersection, for example, when passing the intersection (step S141). In this way, unless the user stops the reproduction, the positioning data is transmitted to the server device 2, and the music corresponding to the traveling road is reproduced by the terminal device 1.

Further, when the server apparatus 2 distributes the music data and the metadata to the terminal apparatus 1 in step S274, the server apparatus 2 stores the history in the distribution management DB 225 as distribution result information (step S275). Specifically, the server device 2 uses the date and time when the music and metadata are transmitted, the link ID corresponding to the road, the music ID of the transmitted music, the ID of the terminal device 1 as the transmission destination, or the user ID as distribution result information. Saved in the distribution management DB 225. Thereby, the server apparatus 2 can accumulate | store actual delivery performance information.

It should be noted that it is preferable that if the user of the terminal device 1 likes the music while the music is distributed, the music can be purchased. For example, when the user operates the terminal device 1 and inputs a purchase instruction, it is transmitted to the server device 2. The server device 2 transmits (downloads and distributes) the music data to the terminal device 1 after completing the payment processing. Thereby, the user can purchase music data and store it in the terminal device 1.

[Modification]
A suitable modification is shown below. Note that the following modifications can be applied to the embodiments in any combination.

(Modification 1)
In the above embodiment, the music is registered in association with the road (link), and the music is distributed when the vehicle equipped with the terminal device 1 is traveling on the road. In this case, the music may be associated not only with the range of the road width but also with a range of a predetermined width centered on the road. For example, music is associated with an area having a width of 100 m in the direction perpendicular to the road from the center of the road. In this case, music distribution can be continued even when the vehicle is slightly off the road, for example, when the vehicle enters a facility along the road.

In the above embodiment, the music is associated with the road (link), but instead or in addition, the music may be registered in association with an intersection (node) or a facility. Specifically, the music may be associated with a predetermined range area (for example, a range with a radius of 200 m) including a node corresponding to the intersection and a specific facility. In this case, the music is played when the vehicle equipped with the terminal device 1 enters the area.

In the above embodiment, the music is associated with the road on the road network, but the present invention can also be applied to the railway network. In this case, a station in the railway network can be regarded as a node, and a track between stations can be regarded as a link. Moreover, a link can also be defined so that a predetermined link between stations is not a separate link between all stations. For example, the entire Yamanote line may be a single link, or the link between Tokyo and Shin-Yokohama on the Shinkansen may be a single link. In this case as well, it is preferable that the music is associated with an area having a predetermined distance around the station (for example, within a radius of 200 m) and between the stations with a predetermined distance (for example, within 100 m) from the track.

(Modification 2)
In the above embodiment, the music distribution fee is determined based on the formula (1), but the distribution fee can be adjusted based on various information.

First, the distribution fee may be changed according to the time zone. For example, the distribution fee may be changed by classifying one day into night and daytime, or a different distribution fee may be set every hour or 30 minutes. In this case, the time zone discount rate “a ₁ ” is introduced as the discount rate in equation (1), and the distribution fee is calculated by multiplying the time zone discount rate “a ₁ ” by the basic discount rate “a”. Good.

Further, based on the traffic volume information, one day may be classified into a plurality of time zones for each traffic volume, and the distribution fee may be changed for each time zone. For example, based on traffic statistics information, one day may be classified into three time zones, a time zone with a high traffic volume, a normal time zone, and a time zone with a low traffic volume, and different delivery charges may be set for them. In this case, the traffic volume discount rate “a ₂ ” is introduced as the discount rate in the equation (1), and the traffic volume discount rate “a ₂ ” that varies depending on the time zone classification depending on the traffic volume is used as the basic discount rate “a ₂ ”. ”To calculate the distribution fee. The process of analyzing the traffic statistical information and classifying the time zone based on the traffic volume can be performed by automatic calculation using a known clustering method such as the k-mins method.

Further, the distribution fee may be changed based on actual traffic conditions. Specifically, based on the traffic statistics information, the distribution fee may be changed according to the time required for traveling one road link (time required for passing), the stop time, the signal waiting time, and the like. As a result, for example, a road link that takes a long time to pass can increase the distribution fee on the assumption that it is suitable for music reproduction. Further, the road link with many parked vehicles has time to operate the terminal device 1 to purchase the music, and the distribution fee can be increased because it is easy to purchase the music. In this case, if the traffic situation discount rate “a ₃ ” is introduced as the discount rate in the equation (1), and the distribution fee is calculated by multiplying the traffic situation discount rate “a ₃ ” by the basic discount rate “a”. Good.

Furthermore, the delivery fee may be changed according to the weather of the day. For example, the delivery fee may be reduced on rainy days, and the delivery fee may be increased on sunny days. In this case, the weather rate discount rate “a ₄ ” is introduced as the discount rate in the equation (1), and the distribution fee may be calculated by multiplying the basic discount rate “a” by the weather discount rate “a ₄ ”. .

(Modification 3)
A plurality of music pieces may be associated with one road link. In that case, the reproduction priority of a plurality of music is defined. For example, with respect to one road link, song A is associated with song 1 at the highest priority, song B at the second highest priority, and song C with the third highest priority. In this case, when the terminal device 1 enters the road link and requests a music piece, the music piece A is first delivered. If there is still time, the music piece B is further delivered, and if there is still time, the music piece C is delivered.

When the reproduction priority is introduced in this way, it is preferable to reflect the reproduction priority in the music distribution fee. That is, the higher the reproduction priority, the higher the distribution fee paid by the distributor. Thus, the distributor can pay a high distribution fee and increase the reproduction priority for the music that is to be distributed preferentially. In this case, if the reproduction priority discount rate “a ₅ ” is introduced as the discount rate in the equation (1), and the distribution fee is calculated by multiplying the reproduction priority discount rate “a ₅ ” by the basic discount rate a. Good. For example, the distribution fee may be increased by 20% with the reproduction priority discount rate “a ₅ = 1.2” of the music with the highest reproduction priority.

(Modification 4)
In the above embodiment, the success fee amount α in the equation (1) is basically applied to all users in the same manner. That is, the success remuneration amount α is determined according to the distribution results (the number of songs, the number of users, the number of terminals) for all the terminal devices 1. Instead, the success remuneration amount α may be determined based on the number of purchased music pieces (the number of purchased music pieces) by the user. Further, the distribution results may be aggregated only for users with specific attributes (age, sex, etc.), and the success fee α may be determined based on the distribution results.

(Modification 5)
In the above embodiment, the server device distributes music data and music metadata, but in addition to this, other related information of the music may be distributed simultaneously. For example, information such as scheduled release date, similar music, recommended music, etc. for unreleased music may be distributed simultaneously.

(Modification 6)
In the above embodiment, the server device 2 calculates traffic statistics information and traffic volume based on the positioning data received from the terminal device 1, but the server device 2 receives traffic statistics information and traffic volume information from an external server or the like.
