A distribution device that distributes a plurality of part data to a reproduction device (30) to be reproduced, the plurality of part data being distributed based on the respective characteristics (112) of the plurality of part data Setting means (121) for setting the priority of each part data, and distribution means (122) for distributing a plurality of part data for each part in the order according to the set priority.

Description

  The present invention provides, for example, a distribution device that distributes a plurality of part data constituting content such as music, a distribution method, a computer program for distribution control, and a reproduction that acquires and reproduces a plurality of part data constituting content such as music. The present invention relates to an apparatus, a playback method, a computer program for playback control, and a technical field of a delivery system including such a delivery device and such a playback device.

  As a distribution system of this type, for example, as described in Patent Document 1, a system in which a client device downloads a plurality of performance data corresponding to a plurality of parts from a server on a network and performs streaming playback is known. Yes. According to such a distribution system, the user uploads the performance data of each part on the server and combines the uploaded performance data as appropriate, so that a desired content (for example, a desired music piece) that suits the taste can be obtained. Can be created and played back.

  On the other hand, the system described above is a system that performs streaming reproduction in which a plurality of performance data is downloaded at the same time and the plurality of performance data downloaded at the same time is reproduced in parallel with the download. In such a system that performs streaming reproduction, there is a technical problem that streaming reproduction is not appropriately performed depending on the relationship between the network capacity of the network between the server and the client device and the amount of performance data to be downloaded. May occur.

  For this reason, instead of streaming playback, it is possible to download a plurality of performance data one by one and adopt a method of playing while mixing sequentially from the downloaded performance data (that is, the data portion of the downloaded performance data) It can be considered as one of the means for solving the technical problems described above. Specifically, for example, when five performance data corresponding to five parts are downloaded, the data portion of the first performance data that has been downloaded is downloaded in parallel with the download of the first performance data. Is played. Thereafter, after all the downloads of the first performance data are completed, the download of the second performance data is started, and in parallel with the download of the second performance data, The performance data and the data portion of the second performance data that has been downloaded are reproduced while being mixed. Thereafter, the same operation is repeated until downloading of all performance data is completed. After downloading all the performance data, all the performance data is reproduced while being mixed. According to this method, even if the network capacity between the server and the client device is insufficient with respect to the amount of performance data to be downloaded, the performance data is downloaded one by one. Technical problems are unlikely to occur.

  However, depending on the order of downloading a plurality of performance data, the following new technical problems arise. For example, depending on the order of downloading a plurality of performance data, it may be difficult for the user to quickly recognize the entire music composed of a plurality of downloaded performance data. Specifically, for example, vocal part performance data, guitar part performance data, chorus part performance data, drum part performance data, and base part performance data are downloaded as a plurality of performance data. An example will be described. In this example, assuming that the performance data of the chorus part and the performance data of the bass part are downloaded first, only the chorus part and the bass part are played while being mixed. It can be assumed that the situation is difficult. For this reason, it is considered preferable to appropriately set the download order of a plurality of performance data.

  Such a technical problem may occur not only in performance data that constitutes a musical piece, but also in a delivery system that delivers a plurality of part data constituting arbitrary content (for example, video or the like).

  Examples of problems to be solved by the present invention include the above.

  Hereinafter, embodiments of a distribution apparatus, a distribution method, a computer program for distribution control, a reproduction apparatus, a reproduction method, a computer program for reproduction control, and a distribution system will be described in order.

(Embodiment of distribution apparatus)
The distribution apparatus according to the present embodiment acquires a plurality of part data, which are data portions respectively corresponding to a plurality of parts constituting the content, one by one for each part, and reproduces the mixed data in order from the acquired part data. A reproducing apparatus that distributes the plurality of part data to a reproducing apparatus that performs the distribution of the plurality of part data based on the characteristics of each of the plurality of part data. A setting unit configured to set each priority; and a distribution unit configured to distribute the plurality of part data to the playback apparatus for each part in an order corresponding to the priority set by the setting unit.

  According to the distribution apparatus of the present embodiment, the distribution unit distributes a plurality of part data to the reproduction apparatus. The distribution means may distribute a plurality of part data in response to a request from the playback apparatus, or may spontaneously distribute a plurality of part data regardless of a request from the playback apparatus.

  Each part data is a data portion corresponding to any one of a plurality of parts constituting the content. For example, if the content is a song, a data portion corresponding to any one of a plurality of instrument parts or performance parts constituting the song (for example, a data portion corresponding to vocals or data corresponding to a guitar) (Part) is an example of each part data. Or, for example, when the content is a video, the data portion corresponding to any one of a plurality of partial videos constituting the entire video (for example, corresponding to the partial video of the first portion of the entire video) Data portion corresponding to the second partial video of the entire video) is an example of each part data.

  The playback apparatus acquires a plurality of part data one by one for each part. That is, the playback device acquires certain part data, and starts acquiring the next part data after the acquisition of the part data is completed. Also, the playback device plays back while mixing in order from the acquired part data. That is, the playback device plays back the part data that has been acquired and the part data that is currently being acquired while mixing (in other words, synthesizing).

  In particular, the distribution apparatus according to the present embodiment further includes setting means. The setting means sets the priority of each of the plurality of part data when distributing the plurality of part data to the playback device. At this time, the setting means sets the priority of each of the plurality of part data based on the characteristics (in other words, characteristics or specifications) of the plurality of part data. More specifically, for example, the setting unit distributes each of the plurality of part data to the playback device in an appropriate order based on the characteristics of the plurality of part data (in other words, the appropriate order). It is preferable to set the priority of each of the plurality of part data as obtained by the playback device. From this point of view, the characteristics of each of the plurality of part data referred to when setting the priority are characteristics that make it possible to appropriately set the distribution order of each of the plurality of part data. May be included.

  As a result, the distribution unit distributes the plurality of part data to the playback device in the order corresponding to the priority set by the setting unit. In other words, in the present embodiment, the distribution unit replaces the plurality of part data with the plurality of part data according to the characteristics of the plurality of part data, instead of distributing the plurality of part data to the playback device in a random order. Can be distributed to the playback device in a particular order.

  For example, taking as an example the case where the content is music and the part data is a data part corresponding to a musical instrument part or a performance part, the technical effect realized by the distribution apparatus of the present embodiment will be described. In this case, for example, the distribution means can easily recognize the whole piece of music by listening to a plurality of part data corresponding to a plurality of instrument parts, for example, a user (that is, a user of the playback device) listening to the performance of the acquired part data. It can be delivered for each part in an appropriate order. As a result, the user can recognize what kind of music the delivered music is at an earlier stage. As described above, the distribution device according to the present embodiment distributes a plurality of part data in an appropriate order derived from the viewpoint that the user can quickly recognize what kind of music the distributed music is. can do.

  In one aspect of the distribution apparatus of the present embodiment, each characteristic of the plurality of part data includes a degree of contribution of each of the plurality of part data to a degree of recognition of the content by a user.

  According to this aspect, the setting means can each of the plurality of part data from the viewpoint that the user can quickly recognize what kind of content is composed of the plurality of distributed part data. You can set the priority. As a result, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of content is composed of the plurality of distributed part data. can do.

  As described above, in the aspect of the distribution apparatus in which each characteristic of the plurality of part data includes the magnitude of the contribution degree of each of the plurality of part data with respect to the recognition degree of the content by the user, the setting unit includes: A higher priority may be set for part data that has a higher contribution to the recognition level, and the distribution unit may be configured to distribute the plurality of part data in order from the part data with the higher priority. .

  With this configuration, the setting means quickly recognizes the priority of part data that makes it easy for the user to quickly recognize what content the content is, and what the content is content quickly. It can be made higher than the priority of the part data that is difficult to make. As a result, the distribution means provides part data that makes it easy for the user to quickly recognize what kind of content is ahead of part data that makes it difficult for the user to quickly recognize what kind of content the content is. Can be delivered to. Therefore, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of content is the content composed of the plurality of part data to be distributed. be able to.

  As described above, in the aspect of the distribution apparatus in which each characteristic of the plurality of part data includes the magnitude of each contribution of the plurality of part data to the degree of content recognition by the user, each characteristic of the plurality of part data is: You may comprise so that at least one of the reproduction | regeneration frequency and acquisition frequency of each of these part data by a user may be included.

  If comprised in this way, a setting means will be able to recognize rapidly what kind of content the content comprised from the several part data delivered is, and from a viewpoint of a some part data, Each priority can be set. As a result, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of content is composed of the plurality of distributed part data. can do.

  More specifically, for example, part data having a relatively high reproduction frequency and / or acquisition frequency is more popular with the user than part data having a relatively low reproduction frequency and / or acquisition frequency. It is assumed. In addition, if such popular part data is reproduced, it is assumed that the user can relatively easily recognize what kind of content the content composed of the part data is. For this reason, the setting means, for example, based on at least one of the reproduction frequency and the acquisition frequency of each of the plurality of part data, for example, at least one of the reproduction frequency and the acquisition frequency is relatively high (that is, popular) Can be higher than the priority of part data in which at least one of the reproduction frequency and the acquisition frequency is relatively low (that is, the popularity is low). As a result, at least one of the reproduction frequency and the acquisition frequency is relatively high (that is, the popularity is high), and at least one of the reproduction frequency and the acquisition frequency is relatively low (that is, the popularity is low). ) Can be distributed before part data. In other words, the distribution means prompts the user for part data (that is, popular part data) that makes it easy for the user to quickly recognize what content the content is, and prompts the user for what content the content is. Can be distributed before part data that is difficult to recognize (that is, less popular part data). Therefore, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of content is the content composed of the plurality of part data to be distributed. be able to.

  As described above, in the aspect of the distribution apparatus in which each characteristic of the plurality of part data includes the magnitude of each contribution of the plurality of part data to the degree of content recognition by the user, each characteristic of the plurality of part data is: You may comprise so that the reproduction time of each of these part data may be included.

  If comprised in this way, a setting means will be able to recognize rapidly what kind of content the content comprised from the several part data delivered is, and from a viewpoint of a some part data, Each priority can be set. As a result, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of content is composed of the plurality of distributed part data. can do.

  More specifically, for example, it is assumed that part data with a relatively long playback time occupies a large position or role for playback of the entire content as compared with part data with a relatively short playback time. . In addition, if part data that plays a major role or role in the reproduction of the entire content is reproduced, the user can relatively determine what kind of content the content composed of the part data is. It is assumed that it is easy to recognize. For this reason, the setting means, for example, sets the priority of part data having a relatively long reproduction time to be higher than the priority of part data having a relatively short reproduction time, based on the reproduction times of the plurality of part data. Can be high. As a result, the distribution means can distribute part data having a relatively long reproduction time before part data having a relatively short reproduction time. In other words, the distribution means provides part data (that is, part data that has a long reproduction time) that makes it easy for the user to quickly recognize what content the content is, and tells the user what content the content is. It can be distributed before part data that is difficult to recognize quickly (that is, part data with a short reproduction time). Therefore, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of content is the content composed of the plurality of part data to be distributed. be able to.

  In another aspect of the distribution apparatus of the present embodiment, the content is music, and each of the plurality of part data is performance data corresponding to any one of the plurality of parts.

  According to this aspect, the distribution device supports a plurality of instrument parts or performance parts instead of distributing a plurality of part data corresponding to a plurality of instrument parts or performance parts to the playback device in a random order. The plurality of part data can be distributed to the playback device in an appropriate order according to the characteristics of the plurality of part data.

  In the aspect of the distribution apparatus in which the content is music as described above, the characteristics of each of the plurality of part data include the magnitude of each contribution of the plurality of part data to the degree of recognition of the music by the user. You may comprise.

  If comprised in this way, a setting means will be able to recognize quickly what kind of music the music comprised from the several part data delivered is a part of music of several part data. Each priority can be set. As a result, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of music is composed of the plurality of distributed part data. can do.

  As described above, in the aspect of the distribution apparatus in which each characteristic of the plurality of part data includes the magnitude of the contribution degree of each of the plurality of part data to the degree of recognition of the music by the user, the setting unit includes: A higher priority may be set for part data that has a higher contribution to the recognition level, and the distribution unit may be configured to distribute the plurality of part data in order from the part data with the higher priority. .

  With this configuration, the setting means quickly recognizes the priority of part data that makes it easy for the user to quickly recognize what kind of music the music is and what kind of music the music is. It can be made higher than the priority of the part data that is difficult to make. As a result, the distribution means provides part data that makes it easy for the user to quickly recognize what kind of music is ahead of part data that makes it difficult for the user to quickly recognize what kind of music the music is. Can be delivered to. Therefore, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of music is composed of the plurality of part data to be distributed. be able to.

  As described above, in the aspect of the distribution apparatus in which each characteristic of the plurality of part data includes the magnitude of each contribution of the plurality of part data to the degree of music recognition by the user, each characteristic of the plurality of part data is: You may comprise so that the kind of part corresponding to each of the said some part data may be included.

  If comprised in this way, a setting means will be able to recognize quickly what kind of music the music comprised from the several part data delivered is a part of music of several part data. Each priority can be set. As a result, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of music is composed of the plurality of distributed part data. can do.

  More specifically, for example, when part data corresponding to a specific type of part is reproduced, compared to the case where part data corresponding to other types of parts is reproduced, the user It is assumed that it is relatively easy to recognize what kind of music is composed of data. For this reason, the setting means sets, for example, the priority of the part data corresponding to the musical instrument of the specific part based on the type of the part corresponding to each of the plurality of part data, to the part corresponding to other types of parts. It can be higher than the priority of data. As a result, the distribution means can distribute part data corresponding to a specific part before part data corresponding to other types of parts. In other words, the distribution means uses part data (that is, part data corresponding to a specific type of part) that allows the user to quickly recognize what kind of music the music is, and what kind of music the music is. Can be distributed before part data that is difficult for the user to quickly recognize (that is, part data corresponding to other types of parts). Therefore, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of music is composed of the plurality of part data to be distributed. be able to.

  As described above, in the aspect of the distribution apparatus in which each characteristic of the plurality of part data includes the magnitude of each contribution of the plurality of part data to the degree of music recognition by the user, each characteristic of the plurality of part data is: You may comprise so that at least one of the reproduction frequency and acquisition frequency by each user of these part data may be included.

  If comprised in this way, a setting means will be able to recognize quickly what kind of music the music comprised from the several part data delivered is a part of music of several part data. Each priority can be set. As a result, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of music is composed of the plurality of distributed part data. can do.

  More specifically, for example, part data having a relatively high reproduction frequency and / or acquisition frequency is more popular with the user than part data having a relatively low reproduction frequency and / or acquisition frequency. It is assumed. In addition, if such popular part data is reproduced, it is assumed that the user can relatively easily recognize what kind of music is composed of the part data. For this reason, the setting means, for example, based on at least one of the reproduction frequency and the acquisition frequency of each of the plurality of part data, for example, at least one of the reproduction frequency and the acquisition frequency is relatively high (that is, popular) Can be higher than the priority of part data in which at least one of the reproduction frequency and the acquisition frequency is relatively low (that is, the popularity is low). As a result, at least one of the reproduction frequency and the acquisition frequency is relatively high (that is, the popularity is high), and at least one of the reproduction frequency and the acquisition frequency is relatively low (that is, the popularity is low). ) Can be distributed before part data. In other words, the distribution means generates part data (that is, part data that is popular part data and corresponds to a popular instrument) that makes it easy for the user to quickly recognize what kind of music the music is. Can be distributed before part data that is difficult for the user to recognize quickly (that is, part data that is less popular and corresponds to a less popular instrument). Therefore, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of music is composed of the plurality of part data to be distributed. be able to.

  As described above, in the aspect of the distribution apparatus in which each characteristic of the plurality of part data includes the magnitude of each contribution of the plurality of part data to the degree of music recognition by the user, each characteristic of the plurality of part data is: You may comprise so that the reproduction time of each of these part data may be included.

  If comprised in this way, a setting means will be able to recognize quickly what kind of music the music comprised from the several part data delivered is a part of music of several part data. Each priority can be set. As a result, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of music is composed of the plurality of distributed part data. can do.

  More specifically, for example, part data with a relatively long playback time is assumed to occupy a large position or role for playback of the entire music compared to part data with a relatively short playback time. . In addition, if part data that occupies a large position or role for the reproduction of the entire music is reproduced, the user can relatively determine what kind of music the music composed of the part data is. It is assumed that it is easy to recognize. For this reason, the setting means, for example, sets the priority of part data having a relatively long reproduction time to be higher than the priority of part data having a relatively short reproduction time, based on the reproduction times of the plurality of part data. Can be high. As a result, the distribution means can distribute part data having a relatively long reproduction time before part data having a relatively short reproduction time. In other words, the distribution means provides part data (that is, part data having a long reproduction time) that allows the user to quickly recognize what kind of music the music is, and what kind of music the music is to the user. It can be distributed before part data that is difficult to recognize quickly (that is, part data with a short reproduction time). Therefore, the distribution means distributes the plurality of part data in an appropriate order so that the user can quickly recognize what kind of music is composed of the plurality of part data to be distributed. be able to.

  As described above, in the aspect of the distribution apparatus in which each characteristic of the plurality of part data includes the magnitude of each contribution of the plurality of part data to the degree of music recognition by the user, each characteristic of the plurality of part data is: You may comprise so that the information which shows whether the user himself can perform the performance of the part corresponding to each of the said some part data may be included.

  With this configuration, for example, part data corresponding to a part that can be played by the user of the playback device can be supplemented by the user's own performance even if the part data is not acquired by the playback device. It is also assumed that. Therefore, from this point of view, it is assumed that the part data corresponding to the part that can be played by the user of the playback apparatus has a relatively low distribution priority. Therefore, in this case, the setting means determines, for example, the priority of part data corresponding to the part that the user cannot perform according to the type of part that the user can perform. The priority of the part data corresponding to the part that can be performed can be made higher. As a result, the distribution means can distribute the part data corresponding to the part that the user cannot perform before the part data corresponding to the part that the user can perform.

  Alternatively, on the other hand, for example, for part data corresponding to a part that can be played by the user of the playback device, the user is assumed to desire early acquisition and playback of the part data. Therefore, from this point of view, it is assumed that the part data corresponding to the part that can be played by the user of the playback apparatus has a relatively high distribution priority. Therefore, in this case, the setting means determines, for example, the priority of part data corresponding to the part that the user can perform according to the type of part that the user can perform. It is possible to make the priority higher than the priority of the part data corresponding to the part that cannot be performed. As a result, the distribution means can distribute the part data corresponding to the part that the user can perform before the part data corresponding to the part that the user cannot perform.

  In another aspect of the distribution apparatus of the present embodiment, the distribution device further includes storage means for storing characteristic data indicating characteristics of each of the plurality of part data, and the setting means includes the plurality of parts stored in the storage means. The priority of each of the plurality of part data when the plurality of part data is distributed is set based on each characteristic of the data.

  According to this aspect, the setting means can relatively easily specify each characteristic of the plurality of part data by referring to the characteristic data stored in the storage means such as a memory. For this reason, the setting means can appropriately set the priority of each of the plurality of part data.

(Embodiment of delivery method)
The distribution method of the present embodiment acquires a plurality of part data, which are data portions respectively corresponding to a plurality of parts constituting the content, one by one in order for each part, and reproduces the mixed data in order from the acquired part data. A delivery method for delivering the plurality of part data to a playback device, wherein the plurality of part data at the time of delivering the plurality of part data is based on characteristics of each of the plurality of part data. A setting step for setting each priority, and a distribution step for distributing the plurality of part data to the playback device for each part in an order corresponding to the priority set in the setting step.

  According to the distribution method of the present embodiment, it is possible to suitably enjoy the same effects as the various effects that can be enjoyed by the above-described distribution apparatus of the present embodiment.

  Further, the computer program for distribution control according to the present embodiment may be recorded on a recording medium (for example, a computer-readable recording medium).

(Embodiment of playback device)
The playback apparatus according to the present embodiment acquires the plurality of part data distributed for each part in the order corresponding to the priority from the distribution apparatus according to the present embodiment described above (including various aspects thereof). And reproducing means for reproducing while mixing in order from the acquired part data among the plurality of part data.

  According to the playback apparatus of this embodiment, the acquisition unit can acquire a plurality of part data distributed from the distribution apparatus in an appropriate order for each part. In other words, the acquisition means can acquire a plurality of part data in an appropriate order for each part. As a result, the playback means can play back while mixing in order from the part data acquired in an appropriate order.

  For example, taking as an example the case where the content is music and the part data is a data part corresponding to a musical instrument part, the technical effect realized by the playback apparatus of the present embodiment will be described. In this case, for example, the acquisition unit recognizes the whole piece of music by listening to a plurality of part data corresponding to a plurality of instrument parts, for example, a user (that is, a user of the playback device) listening to the performance of the acquired part data. Can be obtained for each part in an appropriate order. Therefore, for example, the reproduction means recognizes the whole piece of music by the user (that is, the user of the reproduction apparatus) listening to the performance of the acquired part data, for example, a plurality of part data corresponding to a plurality of instrument parts. It is possible to play while mixing in an appropriate and easy order. As a result, the user can recognize what kind of music the delivered music is at an earlier stage.

  Incidentally, in response to the various aspects of the distribution apparatus of the present embodiment described above, the playback apparatus of the present embodiment can also adopt various aspects.

  Note that the playback device of the present embodiment is based on the above-described distribution device of the present embodiment (that is, a distribution device that sets the priority of part data and actively distributes part data in an order corresponding to the priority).

The computer program for playback control according to this embodiment causes a computer to function as the playback device according to this embodiment. Therefore, a plurality of part data such as performance data is distributed in an appropriate order.

  Hereinafter, embodiments of a distribution device, a distribution method, a computer program reproduction device for distribution control, a reproduction method, a computer program for reproduction control, and a distribution system will be described with reference to the drawings. In the following, as an example of the distribution system, the music server 10 distributes the music (more specifically, a plurality of part data constituting the music) from the music server 10 to the client terminal 20, and the distributed music is used as the client terminal. The description will be given by using the music playback system 1 that plays back on the computer 20. However, as a distribution system, a distribution system for any content other than music (for example, video, still images, text data, and other arbitrary data) may be employed.

(1) Configuration of Music Distribution System First, the configuration of the music distribution system 1 of the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing the configuration of the music distribution system 1 of this embodiment.

  As shown in FIG. 1, the music distribution system 1 includes a music server 10, a client terminal 20, and a network 30.

  The music server 10 stores a plurality of part data constituting music. The part data stored in the music server 10 is, for example, part data uploaded (in other words, transmitted) from the client terminal 20 to the music server 10. However, the music server 10 may store part data acquired in other manners. Each part data corresponds to performance data corresponding to one of a plurality of parts constituting the music (that is, one of a plurality of instrument parts or performance parts). Part data will be described later in detail (see FIG. 3 and the like).

  In addition, the music server 10 distributes (in other words, transmits) desired part data to the client terminal 20 in response to a request from the client terminal 20.

  The client terminal 20 uploads part data to the music server 20. The part data uploaded by the client terminal 20 is, for example, part data created by the user of the client terminal 20 actually playing a musical instrument. However, the client terminal 20 may upload part data created or acquired in other manners.

  In addition, the client terminal 20 requests the music server 10 to distribute desired part data among a plurality of part data stored in the music server 10. As a result, the client terminal 20 downloads (in other words, obtains or receives) desired part data distributed from the music server 10. Thereafter, the client terminal 20 may reproduce the acquired part data.

  The network 30 is a network line that connects the music server 10 and the client terminal 20. The network 30 may be a wired network line, a wireless network line, or a combination of a wired network line and a wireless network line.

  FIG. 1 shows an example in which the music distribution system 1 includes one music server 10. However, the music distribution system 1 may include a plurality of music servers 10. In this case, the client terminal 20 may upload part data to at least one of the plurality of music servers 10 and download part data from at least one of the plurality of music servers 10.

  FIG. 1 shows an example in which the music distribution system 1 includes one client terminal 20. However, the music distribution system 1 may include a plurality of client terminals 20. In this case, a certain client terminal 20 may download part data uploaded by another client terminal 20.

(2) Configuration of Music Server Next, the configuration of the music server 10 of this embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing the configuration of the music server 10 of this embodiment.

  As shown in FIG. 2, the music server 10 includes a database 110, a control unit 120, a display unit 130, and a data communication unit 140.

  The database 110 stores a part data storage unit 111 for storing a plurality of part data uploaded from the client terminal 20, and system possession information indicating characteristics of the plurality of part data stored in the part data storage unit 111. A system possession information storage unit 112.

  Here, with reference to FIG.3 and FIG.4, the some part data stored in the part data storage part 111 with which the database 110 is provided are demonstrated. Here, FIGS. 3 and 4 are schematic diagrams showing a plurality of part data modes stored in the part data storage unit 111 included in the database 110, respectively.

  As shown in FIG. 3, the part data storage unit 111 preferably stores a plurality of part data in a state classified according to a predetermined rule. Here, as an example of the rules, there are a song name of a song composed of part data, a tempo of a song composed of part data, and the like. Therefore, it is preferable that one or a plurality of part data constituting music pieces having the same music title and having the same tempo constitute a data group classified according to the same rule. For example, in the example shown in FIG. 3, one or a plurality of part data constituting a song having a song name “XXX” and a tempo “102 bpm (Beat Per Minute)” is rule A. Are stored in the part data storage unit 111 in a state in which a data group classified into these categories is configured. Similarly, in the example shown in FIG. 3, one or a plurality of part data constituting a song whose song name is “xxx” and whose tempo is “88 bpm” is classified into a rule B. Are stored in the part data storage unit 111 in a state where a data group is configured.

  In order to store a plurality of part data in a state classified according to such rules, each time the new part data is stored, the part data storage unit 111 stores the song name, tempo, etc. of the new part data (that is, It is preferable to classify the new part data according to the rules by analyzing the characteristics that characterize the rules).

  In addition, the part data storage unit 111 preferably stores a plurality of part data constituting a data group classified by the same rule in a state of being classified for each part. For example, in the example shown in FIG. 3, a plurality of part data constituting a data group classified into the rule A is one or a plurality of part data corresponding to a lead guitar and one or a plurality of parts corresponding to a chorus. Data, one or a plurality of part data corresponding to a base, one or a plurality of part data corresponding to a drum, and one or a plurality of part data corresponding to a vocal are stored. Similarly, in the example illustrated in FIG. 3, a plurality of part data constituting a data group classified into the category of rule B includes one or a plurality of part data corresponding to the lead guitar and one or a plurality of part data corresponding to the base. The data is stored in a state classified into part data, one or more part data corresponding to the drum, and one or more part data corresponding to the vocal.

  In order to store a plurality of part data in such a state classified for each part, each time the new part data is stored, the part data storage unit 111 analyzes the part corresponding to the new part data. Thus, it is preferable to classify the new part data for each part.

  Alternatively, as shown in FIG. 4, the part data storage unit 111 may store a plurality of part data constituting a data group classified according to the same rule in a state of being grouped in units of bands. . Here, the “band” refers to a set of one or a plurality of parts for constituting one musical piece. That is, a plurality of part data collected in units of bands are reproduced while being mixed on the client terminal 20, so that a state where one piece of music is played by a virtual band is substantially realized. . In the example shown in FIG. 3, in the data group classified into the rule A, one part data corresponding to the lead guitar, one part data corresponding to the drum, and one part data corresponding to the vocal And a group of data from a combination of one part data corresponding to the base and stored in a unit of band # 1. Similarly, in the example shown in FIG. 3, in the data group classified into the category of rule A, one part data corresponding to the lead guitar, one part data corresponding to the drum, and 1 corresponding to the base A group of data from a combination of two part data is stored in a state of being grouped in units of band # 2. The band # 2 data group corresponds to a so-called “minus one” data group that does not include part data corresponding to vocals, as compared to the band # 1 data group.

  At this time, each part data stored in a grouped unit of band is stored together with mixing information indicating a setting mode (for example, volume, pan, etc.) when mixing with other part data. Also good. Therefore, when mixing a plurality of part data collected in units of bands, the client terminal 20 preferably mixes with reference to mixing information recorded together with each part data. Thereby, the client terminal 20 can perform appropriate mixing of a plurality of part data.

  Such a part data storage unit 111 for each rule, for each part, or for each band is logically realized by predetermined management information stored in the part data storage unit 111 together with the part data, for example. It is preferred that For example, the part data storage unit 111 stores a plurality of part data itself as they are without being directly distinguished, and manages classification for each part or band for each rule of the stored part data. It is preferable to store the management information separately. In this case, the music server 10 can recognize that a plurality of part data is stored on the part data storage unit 111 in the manner shown in FIGS. 3 and 4 by referring to the management information. However, the part data storage unit 111 may physically realize storage for each part, for each part, or for each band by dividing a physical partition.

  Next, system possession information stored in the system possession information storage unit 112 included in the database 110 will be described with reference to FIG. FIG. 5 is a schematic diagram showing an aspect of system possession information stored in the system possession information storage unit 112 included in the database 110.

  As shown in FIG. 5, in the system possession information storage unit 112, as system possession information, a score (in other words, a score or a weight) according to a characteristic of a part type and a characteristic of usage frequency (popularity) of the part are included. Records including a score according to the characteristic of the performance time of the part and a score according to the characteristic of the part that can be played by the user are stored in a state classified for each part.

  The score corresponding to the characteristic of the type of part is preferably set from the viewpoint of how much the user can recognize the entire music piece by reproducing the part data corresponding to each part. It is preferable that a higher score is set for the score corresponding to the characteristic of the type of the part, as the part is easier to be recognized by the user by reproducing the part data corresponding to each part. In the example shown in FIG. 5, a score of “6” is set for “drum”, a score of “9” is set for “lead guitar”, and a score of “7” is set for “bass”. Is set, a score of “5” is set for “keyboard”, a score of “2” is set for “rhythm guitar”, a score of “10” is set for “vocal”, A score of “1” is set for “Chorus”. Therefore, in the example shown in FIG. 5, the degree to which the user recognizes the entire music piece by reproducing the part data corresponding to “vocal” is recognized by the user by reproducing the part data corresponding to “chorus”. It can be said that it is higher than the degree. Of course, the setting of the score shown in FIG. 5 is an example, and other scores may be set.

  The score corresponding to the characteristic of the usage frequency (popularity) of the part is preferably set from the viewpoint of how much the user can recognize the entire music piece by reproducing the part data corresponding to each part. In this case, it is presumed that the user can easily recognize the entire music piece by reproducing the part data corresponding to the part because the part whose usage frequency is relatively high is more popular. Therefore, the higher the score according to the characteristic of part usage frequency, the higher the number of times that the part data corresponding to each part is requested, or the number of times acquired or played (that is, the more popular) is. It is preferred that In the example shown in FIG. 5, a score of “5” is set for “drum”, a score of “3” is set for “lead guitar”, and a score of “4” is set for “bass”. Is set, a score of “2” is set for “keyboard”, a score of “8” is set for “rhythm guitar”, a score of “10” is set for “vocal”, A score of “4” is set for “Chorus”. Therefore, in the example shown in FIG. 5, the number of times that the part data corresponding to “vocal” is requested, or acquired or reproduced, is the number of times that the part data corresponding to “chorus” is requested. Or it can be said that it is more than the number of times of reproduction. As a result, in the example shown in FIG. 5, the degree to which the user recognizes the entire music piece by playing the part data corresponding to “vocal” is recognized by the user by playing the part data piece corresponding to “chorus”. It can be said that it is higher than the degree to do. Of course, the setting of the score shown in FIG. 5 is an example, and other scores may be set.

  In addition, the score according to the characteristic of the usage frequency (popularity) of the part is not only the number of times the part data corresponding to each part is requested, acquired or reproduced, but also the part data corresponding to each part. The number of times of combining (that is, mixing) with other part data may be set in further consideration. In this case, it is preferable that a relatively high score is set for a part having a larger number of times of combination with other part data. In this case, a relatively high score is set for a part that can be easily combined with other part data.

  The score corresponding to the characteristic of the performance time of the part is preferably set from the viewpoint of how much the user can recognize the entire music piece by reproducing the part data corresponding to each part. In this case, it is assumed that the part whose performance time of the part is relatively long is that the user can easily recognize the entire music piece by reproducing the part data corresponding to the part. Therefore, it is preferable that a higher score is set for a score corresponding to the characteristic of the performance time of a part as the performance time of the part is relatively longer. In the example shown in FIG. 5, a score of “6” is set for “drum”, a score of “9” is set for “lead guitar”, and a score of “7” is set for “bass”. Is set, a score of “5” is set for “keyboard”, a score of “2” is set for “rhythm guitar”, a score of “10” is set for “vocal”, A score of “1” is set for “Chorus”. Therefore, in the example shown in FIG. 5, it can be said that the reproduction time of the part data corresponding to “vocal” is longer than the reproduction time of the part data corresponding to “chorus”. As a result, in the example shown in FIG. 5, the degree to which the user recognizes the entire music piece by playing the part data corresponding to “vocal” is recognized by the user by playing the part data piece corresponding to “chorus”. It can be said that it is higher than the degree to do. Of course, the setting of the score shown in FIG. 5 is an example, and other scores may be set.

  The score according to the three characteristics described above is a score set mainly from the viewpoint of how much the user can recognize the entire music piece by reproducing the part data corresponding to each part. However, the system possession information may further include a score of a characteristic other than the three characteristics described above. In this case, the system possession information is a characteristic other than the above three characteristics, and the degree to which the user can recognize the entire music piece by reproducing the part data corresponding to each part is appropriate or appropriate. Preferably, it includes scores for other properties that can be shown in

  On the other hand, the score corresponding to the characteristic of the part that the user can play is whether or not the user (that is, the user of the client terminal 20) can play the part (or the user owns the instrument of the part). It is preferably set according to whether or not. For example, the score of the part that the user can perform may be set to be lower than the score of the part that the user cannot perform. For example, in the example shown in FIG. 5, the score of the part that the user can perform is set to “0”, and the score of the part that the user cannot perform is set to “10”. Alternatively, for example, the score of the part that the user can play may be higher than the score of the part that the user cannot play.

  In addition, the system possession information storage unit 112 stores, as system possession information, for each characteristic, a coefficient to be multiplied when calculating the priority described later with respect to the score corresponding to each of the characteristics described above. May be.

  The system possession information storage unit 112 stores a plurality of system possession information separately prepared for each unit of classification or band, which is a rule for storing a plurality of part data in the part data storage unit 111. May be. Alternatively, the system possession information storage unit 112 may store single system possession information common to a plurality of part data stored in the part data storage unit 111. Alternatively, the system possession information storage unit 112 may store a plurality of system possession information separately prepared for each user. Alternatively, the system possession information storage unit 112 may store single system possession information common to all users who use the music distribution system 1.

  In FIG. 2 again, the control unit 120 is a central control device (for example, CPU: Central Processing Unit) that controls the operation of the entire music server 10. The control unit 120 includes a priority setting unit 121 and a data communication control unit 122 as physical, logical, or functional processing blocks realized therein.

  The priority setting unit 121 is a specific example of “setting means”, and based on the system possession information, the priority (in other words, distribution) when distributing a plurality of part data requested by the client terminal 20 Order). Note that the detailed operation of the priority setting unit 121 will be described later in detail (see FIG. 8), and thus the description thereof is omitted here.

  The data communication control unit 122 is a specific example of “distribution means”, and distributes a plurality of part data requested by the client terminal 20 in the order according to the priority set by the priority setting unit 121. In this manner, the data communication unit 140 is controlled. In the present embodiment, the data communication control unit 122 preferably distributes a plurality of part data one by one. That is, the data communication control unit 122 does not distribute other part data while distributing certain part data, but distributes the next part data after the distribution of the certain part data is completed. It is preferable to do.

  In addition, the data communication control unit 122 controls the data communication unit 140 to receive part data uploaded from the client terminal 20. The data communication control unit 122 stores the received part data in the part data storage unit 111.

  The display unit 130 displays a predetermined screen (for example, an operation screen for instructing an operation of the music server 10 or a status screen showing the state of the music server 10).

  The data communication unit 140 performs communication with the client terminal 20 via the network 30 under the control of the data communication control unit 124. Therefore, the part data uploaded from the client terminal 20 is acquired by the data communication unit 140. The acquired part data is stored in the part data storage unit 111 by the data communication control unit 122. Also, the part data requested from the client terminal 20 is read from the part data storage unit 111 by the data communication control unit 122. The read part data is distributed from the data communication unit 140 to the client terminal 20 under the control of the data communication control unit 122.

(3) Configuration of Client Terminal Next, the configuration of the client terminal 20 of this embodiment will be described with reference to FIG. FIG. 6 is a block diagram showing the configuration of the client terminal 20 of this embodiment.

  As shown in FIG. 6, the client terminal 20 includes a storage device 210, a control unit 220, a display unit 230, a data communication unit 240, a voice input unit 250, a voice output unit 260, and an operation unit 270. Prepare.

  The storage device 210 temporarily or permanently stores data used in the process of data processing in the client terminal 20. Examples of the storage device 210 include a semiconductor memory such as a ROM, a RAM, and a flash memory, a hard disk, and the like.

  The control unit 220 is a central control device (for example, CPU: Central Processing Unit) that controls the operation of the entire client terminal 20. The control unit 220 includes a display control 221, an audio control unit 222, an operation control unit 223, and a data communication control unit 224 as physical, logical, or functional processing blocks realized therein. I have.

  The display control unit 221 displays a predetermined screen (for example, a screen for accepting an operation instruction of the client terminal 20 from the user, a screen showing the state of the client terminal 20 to the user, or the like). The operation of the display unit 230 is controlled. In this embodiment, the display control unit 221 issues an instruction to record user performance data (that is, part data) via the audio input unit 250 and an instruction to upload the recorded part data to the music server 10. You may display the screen for receiving from a user. In addition, the display control unit 221 may display a screen for accepting an instruction to download a desired part data among a plurality of part data stored in the music server 10 from the user.

  The voice control unit 222 controls recording of voice (for example, voice of vocal or chorus, voice by performance of each instrument, etc.) via the voice input unit 250. The recorded sound may be temporarily or permanently stored in the storage device 210. In addition, the audio control unit 222 controls the output of the part data downloaded from the music server 10 as audio from the audio output unit 260.

  The operation control unit 223 receives a user operation using the operation unit 270 and notifies each unit in the client terminal 20 of the content of the received user operation so that an operation according to the received operation is performed. For example, when the operation control unit 223 receives a user operation for instructing recording of performance data (that is, part data) of the user via the audio input unit 250, the operation control unit 223 indicates that the operation has been received. 222 is notified. As a result, the voice control unit 222 controls the operation of the voice input unit 250 so as to record user performance data.

  For example, when the data communication control unit 224 receives a notification from the operation control unit 223 that the user's operation for instructing uploading of part data has been received, the recorded part is controlled under the control of the audio control unit 222. The data communication control unit 224 is controlled to upload the data to the music server 10. As a result, the part data recorded under the control of the voice control unit 222 is uploaded from the client terminal 20 to the music server 10 via the data communication unit 240.

  In addition, the data communication control unit 224, for example, notifies the user that an instruction from the operation control unit 223 for requesting download of desired part data among a plurality of part data stored in the music server 10 has been received. If received, the data communication unit 240 is controlled to transmit a message requesting the music server 10 to download the desired part data. As a result, desired part data is downloaded from the music server 10 to the client terminal 20 via the data communication unit 240.

  Here, with reference to FIG. 7, the download and reproduction of desired part data realized by the control of the data communication control unit 224 will be described. FIG. 7 is a schematic diagram schematically showing a manner of downloading and playing back desired part data realized by the control of the control unit 220.

  As shown in FIG. 7, for example, the client terminal 20 can select from among a plurality of part data corresponding to the lead guitar included in the data group classified into the rule A under the control of the data communication control unit 224. , Download of one desired part data may be requested. Similarly, under the control of the data communication control unit 224, the client terminal 20 selects one desired part data from among a plurality of part data corresponding to the chorus included in the data group classified into the category of rule A. You may request a download. Similarly, under the control of the data communication control unit 224, the client terminal 20 selects a desired piece of part data from a plurality of part data corresponding to the base included in the data group classified into the category of rule A. You may request a download. Similarly, under the control of the data communication control unit 224, the client terminal 20 selects desired one part data from among a plurality of part data corresponding to drums included in the data group classified into the rule A. You may request a download. Similarly, under the control of the data communication control unit 224, the client terminal 20 selects desired one part data from a plurality of part data corresponding to vocals included in the data group classified into the category of rule A. You may request a download.

  As a result, under the control of the data communication control unit 224, the client terminal 20 has one part data corresponding to the lead guitar, one part data corresponding to the chorus, one part data corresponding to the base, One part data corresponding to the drum and one part data corresponding to the vocal are downloaded one by one for each part. At this time, the client terminal 20 may reproduce the downloaded part data while mixing under the control of the audio control unit 222. For example, when the download of the part data corresponding to the lead guitar has been completed, the part data corresponding to the chorus has been downloaded, and the download of the part data corresponding to the other parts has not started, the client terminal 20 The part data corresponding to the lead guitar and the part data corresponding to the chorus (particularly, the data part of which the download has been completed) may be mixed and reproduced.

  In FIG. 2 again, the data communication unit 240 performs communication with the music server 10 via the network 30 under the control of the data communication control unit 224. Accordingly, the part data uploaded from the client terminal 20 is transmitted to the music server 10 via the data communication unit 240. In addition, part data distributed from the music server 10 in response to a request from the client terminal 20 is acquired by the data communication unit 240. The acquired part data may be temporarily or permanently stored in the storage device 210 by the data communication control unit 224, or may be output from the audio output unit 260.

  The voice input unit 250 is a device that accepts voice input, such as a microphone.

  The audio output unit 260 is a device that outputs audio such as a speaker.

  The operation unit 270 is a device that receives user operations such as a keyboard, a mouse, and a touch panel.

(4) Flow of Operation in Music Distribution System Next, with reference to FIG. 8, the flow of operation in the music distribution system 1 of the present embodiment will be described. FIG. 8 is a flowchart showing the flow of operations in the music distribution system 1 of the present embodiment.

  As shown in FIG. 8, the client terminal 20 requests the music server 10 to download desired part data among a plurality of part data stored in the music server 10 under the control of the data communication control unit 224. (Step S201). Specifically, for example, the user of the client terminal 20 operates while watching a screen (for example, a screen for selecting desired part data) displayed on the display unit 230 under the control of the display control unit 221. Desired part data is designated by an operation using the part 270. The operation using the operation unit 270 by the user is detected by the operation control unit 223. As a result, the operation control unit 223 can specify desired part data requested by the user for download. As a result, the data communication control unit 224 that receives the notification from the operation control unit 223 uses the data communication unit 240 to send a predetermined message or control signal that can identify the desired part data that the user requests to download. It transmits to the music server 10.

  As a result, the priority setting unit 121 and the data communication control unit 122 of the music server 10 can specify a predetermined message or control signal through which the user can request desired part data via the data communication unit 140. Receive. In this case, first, the priority setting unit 121 sets the priority for distributing the desired part data requested by the user based on the system possession information stored in the system possession information storage unit 112. Set (step S101).

  Here, the priority setting operation by the priority setting unit 121 will be described with reference to FIG. FIG. 9 is a data structure diagram illustrating the priority setting operation by the priority setting unit 121 in association with the system possession information. The system possession information shown in FIG. 9 is the same as the system possession information shown in FIG.

  As illustrated in FIG. 9, the priority setting unit 121 sets, for each part, a numerical value obtained by adding a multiplication value of each characteristic score and each characteristic coefficient over all characteristics as a priority. Setting (in other words, calculating). For example, for the part “drum”, the priority setting unit 121 targets 6 × 3 (that is, the product of the characteristic score of the part type and the coefficient of the characteristic of the part type) + 5 × 2 (that is, (Multiplication value of score of characteristic of use frequency and coefficient of characteristic of use frequency) + 10 × 4 (that is, multiplication value of score of characteristic of performance time and coefficient of characteristic of performance time) + 10 × 1 (that is, user's A numerical value of “78” is set as the priority of the part “drum”. Similarly, for example, the priority setting unit 121 sets the numerical value 9 × 3 + 3 × 2 + 9 × 4 + 10 × 1 = “79” as the priority of the part “lead guitar” for the part “lead guitar”. To do. Similarly, for example, the priority setting unit 121 sets the numerical value 7 × 3 + 4 × 2 + 9 × 4 + 0 × 1 = “65” as the priority of the part “base” for the part “base”. Similarly, for example, the priority setting unit 121 sets a numerical value of 5 × 3 + 2 × 2 + 7 × 4 + 10 × 1 = “57” as the priority of the part “keyboard” for the part “keyboard”. Similarly, for example, the priority setting unit 121 sets the numerical value 2 × 3 + 8 × 2 + 2 × 4 + 10 × 1 = “40” as the priority of the part “rhythm guitar” for the part “rhythm guitar”. To do. Similarly, for example, the priority setting unit 121 sets the numerical value 10 × 3 + 10 × 2 + 6 × 4 + 10 × 1 = “84” as the priority of the part “vocal” for the part “vocal”. Similarly, for example, the priority setting unit 121 sets the numerical value 1 × 3 + 4 × 2 + 3 × 4 + 10 × 1 = “33” as the priority of the part “chorus” for the part “chorus”. The priority setting unit 121 notifies the data communication control unit 122 of the priority of each part set in this way.

  In the example shown in FIG. 9, the coefficients included in the system possession information are set in advance. However, the coefficient included in the system possession information may be sequentially changed by the operation of the priority setting unit 121, for example.

  In FIG. 8 again, subsequently, the data communication control unit 122 distributes the desired part data requested by the user for each part in the order according to the priority set in step S101. (Step S102). At this time, it is preferable that the data communication control unit 122 distributes part data corresponding to a part with high priority before part data corresponding to a part with low priority. In other words, the data communication control unit 122 distributes the desired part data that the user requests to download, one by one for each part in order of priority (see FIG. 9).

  More specifically, for example, the desired part data that the user requests to download corresponds to the part data corresponding to the lead guitar, the part data corresponding to the chorus, the part data corresponding to the base, and the drum. And part data corresponding to vocals. In this case, according to the priority shown in FIG. 9, the data communication control unit 112 first distributes the part data corresponding to the vocal with the highest priority. Thereafter, the data communication control unit 112 distributes the part data corresponding to the lead guitar having the second highest priority after the distribution of the part data corresponding to the vocal having the highest priority is completed. Thereafter, the data communication control unit 112 distributes the part data corresponding to the drum having the third highest priority after the distribution of the part data corresponding to the lead guitar having the second highest priority is completed. Thereafter, the data communication control unit 112 distributes the part data corresponding to the base having the fourth highest priority after the distribution of the part data corresponding to the drum having the third highest priority is completed. Thereafter, after the delivery of the part data corresponding to the base having the fourth highest priority is completed, the data communication control unit 112 receives one chorus corresponding to the chorus having the fifth highest priority (in other words, the lowest). Distribute part data.

  As a result, under the control of the data communication control unit 224, the data communication unit 240 included in the client terminal 20 sets the desired part data requested by the user for download in the order of high priority. Download one by one (step S202). In addition, the client terminal 20 reproduces the downloaded part data while mixing under the control of the voice control unit 222.

  For example, part data corresponding to a lead guitar, part data corresponding to a chorus, part data corresponding to a bass, part data corresponding to a drum, and part data corresponding to a vocal correspond to the above-described priorities. An example of delivery in order will be described. In this case, the data communication unit 240 of the client terminal 20 downloads the part data corresponding to the vocal with the highest priority. In parallel with this download, the voice control unit 222 of the client terminal 20 reproduces the part data corresponding to the currently downloaded vocal. As a result, the voice output unit 260 outputs the voice of the part data corresponding to the vocal. Thereafter, after the download of the part data corresponding to the vocal with the highest priority is completed, the data communication unit 240 downloads the part data corresponding to the lead guitar with the second highest priority. In parallel with this download, the audio control unit 222 of the client terminal 20 reproduces the part data corresponding to the vocal that has been downloaded and the part data corresponding to the currently downloaded lead guitar while mixing them. As a result, the sound output unit 260 outputs a sound in which the sound of the part data corresponding to the vocal and the sound of the part data corresponding to the lead guitar are mixed. After that, after the download of the part data corresponding to the lead guitar with the second highest priority is completed, the data communication unit 240 downloads the part data corresponding to the drum with the third highest priority. In parallel with this download, the audio control unit 222 of the client terminal 20 reproduces the part data corresponding to the vocal and lead guitar that have been downloaded and the part data corresponding to the currently downloaded drum while mixing them. . As a result, the sound output unit 260 outputs a sound in which the sound of part data corresponding to vocals, the sound of part data corresponding to a lead guitar, and the sound of part data corresponding to a drum are mixed. Thereafter, after the download of the part data corresponding to the drum having the third highest priority is completed, the data communication unit 240 downloads the part data corresponding to the base having the fourth highest priority. In parallel with this download, the audio control unit 222 of the client terminal 20 mixes the part data corresponding to the vocal, lead guitar, and drum that have been downloaded and the part data corresponding to the currently downloaded base. Reproduce. As a result, the voice output unit 260 mixes the voice of the part data corresponding to the vocal, the voice of the part data corresponding to the lead guitar, the voice of the part data corresponding to the drum, and the voice of the part data corresponding to the base. Sound is output. Thereafter, after the data communication unit 240 completes downloading of the part data corresponding to the base having the fourth highest priority, the part data corresponding to the chorus having the fifth highest priority (in other words, the lowest). Download. In parallel with this download, the voice control unit 222 of the client terminal 20 mixes the part data corresponding to the vocal, lead guitar, and drum base that have been downloaded and the part data corresponding to the currently downloaded chorus. Play while. As a result, the voice output unit 260 supports the voice of part data corresponding to vocals, the voice of part data corresponding to lead guitar, the voice of part data corresponding to drums, and the voice of part data corresponding to bass and chorus. The voice of the part data to be mixed is output.

  As described above, according to the music distribution system 1 of this embodiment, the distribution order of part data can be appropriately set based on the characteristics of the part data (in other words, the characteristics of the part). Here, a technical effect realized by appropriately setting the order of delivery of part data based on the characteristics of part data will be described with reference to FIG. Here, FIG. 10 shows (i) how part data is distributed when the order of distribution of part data based on the characteristics of part data is not set, and (i) parts based on the characteristics of part data. It is a schematic diagram which shows the mode of delivery of part data in the case where appropriate setting of the order of data delivery is performed.

  As shown in FIG. 10 (a), when an appropriate setting of the distribution order of the part data based on the characteristics of the part data is not performed, a plurality of desired part data that the user requests to download are random. It is distributed from the music server 10 in order. For example, in FIG. 10A, part data corresponding to a chorus is first distributed, then part data corresponding to a base is distributed, then part data corresponding to a drum is distributed, An example is shown in which part data corresponding to a vocal is distributed, and subsequently, part data corresponding to a lead guitar is distributed. However, at the stage where the distribution of the part data corresponding to the chorus is completed and the distribution of the part data corresponding to the base is being performed, the client terminal 20 corresponds to the voice and base of the part data corresponding to the chorus. The sound mixed with the sound of part data is output. However, in general, it is difficult for a user to recognize what kind of music the whole music is based on only chorus and bass sounds. For this reason, in order for a user to recognize what kind of music the whole music is, the user needs to wait for delivery of part data corresponding to other parts.

  However, in the present embodiment, as described above, the part data corresponding to the parts with high priority set based on the system possession information are distributed in order. For example, in FIG. 10B, according to the priority set based on the system possession information, the part data corresponding to the vocal is first distributed, then the part data corresponding to the lead guitar is distributed, and then In this example, part data corresponding to a drum is distributed, then part data corresponding to a base is distributed, and then part data corresponding to a chorus is distributed. Therefore, at the stage where the distribution of the part data corresponding to the vocal is completed and the distribution of the part data corresponding to the lead guitar is being performed, the client terminal 20 transmits the voice of the part data corresponding to the vocal and the lead guitar. A sound obtained by mixing the sound of the corresponding part data is output. In general, vocal and lead guitar sounds have a great influence on the rhythm of the entire musical composition. For this reason, the user can easily recognize what kind of music the whole music is at a relatively early stage (in other words, without waiting for delivery of all the part data).

  As described above, according to the music distribution system 1 of the present embodiment, the priority of each part data is set based on the system possession information, so that the above-described technical effect can be suitably enjoyed.

  Furthermore, according to the music distribution system 1 of the present embodiment, the score (that is, the score set from the viewpoint of whether the user can recognize the entire music by reproducing the part data corresponding to each part (that is, ( (i) a score according to the characteristic of part type, (ii) a score according to the characteristic of part usage frequency (popularity), and (iii) a score according to the characteristic of performance time of part)) Since the priority of each part data is set based on this, the above-described technical effect can be enjoyed more suitably.

  Specifically, for example, as described above, as the part that is easier for the user to recognize the entire music piece by reproducing the part data corresponding to each part, the score corresponding to the characteristic of the part type has a higher score. Is set. Therefore, the part that is easy to be recognized easily by the user by reproducing the part data corresponding to each part tends to have higher priority. For this reason, the music server 10 can distribute the parts that the user can easily recognize the entire music by reproducing the part data corresponding to each part earlier. Therefore, the priority is set according to the characteristic of the part type, so that the user can easily recognize what kind of music the whole music is at a relatively early stage.

  In addition, for example, as described above, a part whose part data corresponding to each part is requested, and a part that is acquired or reproduced more frequently has a higher score for the score according to the characteristic of part usage frequency. Is done. In other words, the part whose part data corresponding to each part is requested, and which has been acquired or reproduced more frequently, tends to have higher priority. Here, it is assumed that the part whose frequency of use is relatively high is more popular, so that the user can easily recognize the entire music piece by reproducing the part data corresponding to the part. For this reason, the music server 10 can distribute the parts that are easy for the user to recognize the entire music (that is, popular parts) earlier by reproducing the part data corresponding to each part. Therefore, by setting the priority according to the characteristic of part usage frequency, it becomes easier for the user to recognize what kind of music the entire music is at a relatively early stage.

  For example, as described above, a higher score is set for a score corresponding to the characteristic of the part performance time as the part performance time is longer. That is, the priority tends to be higher as the part performance time is longer. Here, it is assumed that the part whose performance time is relatively long is that the user can easily recognize the entire music piece by reproducing the part data corresponding to the part. For this reason, the music server 10 can distribute a part that is easier for the user to recognize the whole music by reproducing part data corresponding to each part (that is, a part having a relatively long performance time). Therefore, by setting the priority according to the characteristic of the performance time of the part, the user can easily recognize what kind of music the whole music is at a relatively early stage.

  In addition, according to the music distribution system 1 of the present embodiment, the priority is also set by the score according to the characteristic of the part that the user can play.

  For example, it is assumed that the part data corresponding to the part that the user can perform can be supplemented by the user's own performance even if the part data is not downloaded to the client terminal 20. Therefore, the score of the part that the user can perform may be lower than the score of the part that the user cannot perform. In this case, the priority of the parts that the user can play tends to be lower than the priority of the parts that the user cannot play. For this reason, the music server 10 can preferentially distribute part data corresponding to parts that the user cannot perform over part data corresponding to parts that the user can perform.

  Alternatively, for part data corresponding to a part that the user can perform, it is assumed that the user wants to download and reproduce the part data at an early stage. Therefore, the score of the part that the user can perform may be higher than the score of the part that the user cannot perform. In this case, the priority of the parts that the user can play tends to be higher than the priority of the parts that the user cannot play. For this reason, the music server 10 can preferentially distribute part data corresponding to a part that the user can perform over part data corresponding to a part that the user cannot perform.

  In the music distribution system 1 described above, the priority for distributing part data is set on the music server 10 side. However, the priority for distributing part data may be set on the client terminal 20 side. That is, the priority setting unit 121 described above may be included in the client terminal 20 in addition to or instead of being included in the music server 10. In this case, when the client terminal 20 requests the music server 10 to download desired part data, the client terminal 20 matches the priority set by the client terminal 20 itself (or the distribution order determined according to the priority). The music server 10 may be notified. In this case, the music server 10 may distribute desired part data in the order corresponding to the priority set by the client terminal 20.

  Further, the present invention can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification, and the distribution device, the distribution method, and the distribution control for such a change can be changed. A computer program, a playback device, a playback method, a computer program for playback control, and a distribution system are also included in the technical idea of the present invention.
