Patent Literature 1 discloses a mechanism for automatically selecting a music piece suitable for a location based on position information. Whether or not the music piece is suitable for the occasion is determined by comparing the values of the environment variable including the position information and the attribute data of the music piece.
However, regarding the music selected based on such a determination, it has not been considered whether or not the user truly determines that the music is suitable for the place.

  Further, the technique described in Patent Document 2 has a problem that when a moving object is moving without having a clear destination, the user cannot associate his or her current situation with the music. was there.

  The present invention has been made in view of the above problems, and one example of an object thereof is to provide a content evaluation device that allows a user to evaluate a relationship between music and a situation at the place.

  A content evaluation device according to the present invention includes: a notification unit that performs notification for inputting an evaluation relating to matching between a content being reproduced and a situation of a place; and an input unit that receives input of an evaluation performed in response to notification by the notification unit. And the notifying unit notifies at different timing for each content.

FIG. 2 is an explanatory diagram for explaining functions of the playback terminal of FIG. 1. FIG. 2 is an explanatory diagram illustrating a configuration of a communication system of the reproduction terminal of FIG. 1. FIG. 2 is a block diagram illustrating a configuration of the playback terminal of FIG. 1. It is a flowchart which shows the processing procedure of content reproduction. FIG. 9 is an explanatory diagram of a process of comparing current status information with a first condition. 9 is a flowchart illustrating a procedure of a process A (in the case of reproduction based on a first condition). It is a flowchart which shows the procedure of a process B (in case of random reproduction). FIG. 3 is a diagram showing a table provided in the database.

  FIG. 1 is a front view of a playback terminal 1 including a content evaluation device according to the present invention. Hereinafter, the configuration of the playback terminal 1 will be described with reference to FIG.

  The reproduction terminal 1 is formed as a thin housing. The reproduction terminal 1 has an operation display section 47, an earpiece 21 near the upper surface 3, and a mouthpiece (not shown) near the lower surface 2. The operation display unit 47 includes the display panel 22 and the touch sensor 24. The operation display unit 47 can further display the title bar 23 and the notification unit 25.

  FIG. 2 is an explanatory diagram for explaining functions of the playback terminal 1 of FIG. Next, an outline of functions of the reproduction terminal 1 will be described with reference to FIG.

  When the reproduction terminal 1 is turned on by a reproduction instruction from the user, the user's current situation (for example, “A: seaside sunset”) is satisfied when a predetermined condition (first condition) is satisfied. , "B: Country Blue Sky", "C: Christmas Night", "D: Rainy Mountain Road"), songs suitable for the situation (for example, "A: Sunrise", "B: Sky "Blue", "C: Kiyoshi no Kyo", "D: Frog song" and landscape images (for example, "A: Sunset over the sea", "B: Clear blue sky", "C: Christmas tree", "D" : Wet young leaves ") automatically play. The reproduced music and the landscape image are automatically acquired from the server.

  Here, the situation of the place (current situation information) is determined from, for example, geographical information such as location, weather and temperature, and road conditions, and current situation information appropriately selected from seasonal information such as seasons and time zones. You. Further, when it is determined that the user is in the car, information related to the running of the car such as lights, vehicle speed, and parking conditions may be included.

When the current status information and the first condition owned by the playback terminal 1 match, the playback terminal 1 starts playback start processing (the following description will be made with reference to FIGS. 9 will be described in detail).
As will be described later, the first condition is a condition stored in the playback terminal 1 as appropriate for starting playback of the content.
Then, the reproduction terminal 1 outputs the current status information to the server 31 through communication. The server 31 to which the current status information has been input by communication searches the content database 32 in which the reproduction conditions are stored, and selects the content stored as the one that best matches the current status information.
Then, the server 31 outputs the music data (song DATAa) and the image data (image DATAa) of the selected content to the reproduction terminal 1 by communication. The term "content data" is used as a generic term for music data and image data.
Upon receiving the content data communication input, the reproduction terminal 1 reproduces the music based on the data and displays the image.

For example, when the reproduction condition conforms to the reproduction condition A (temporal information (time zone): evening, weather information: fine, geographical information (current position): seaside), the reproduction terminal 1 The music data (song DATAa) and the image data (image DATAa) (for example, songs related to the setting sun and the sea, and the landscape image of the setting sun) corresponding to the above are acquired from the database of the server and played back simultaneously.
In the reproduction based on the first condition, the content data corresponding to the reproduction condition is reproduced.

The playback conditions are owned by the server 31. The server 31 receives the current status information acquired by the playback terminal 1, and selects the content determined to be most appropriate to the current status information at that time. (See FIG. 9).
Here, it is determined that the content is most appropriate at that point in time because the reproduction condition changes depending on the evaluation of the content data from a plurality of users. The first condition of the playback terminal 1 is synchronized with the playback condition of the server 31. However, the reproduction condition of the server 31 can always be changed by the evaluation information of a plurality of users. Therefore, at the moment when the synchronization is performed, the first condition and the reproduction condition of the reproduction terminal 1 are the same. However, if the synchronization is not performed, the reproduction condition changes and the first condition and the reproduction condition are changed. The conditions will be different.

Thus, in the reproduction based on the first condition, the user can receive the back music suitable for the actual scenery spreading in front of the user without having to select / decide by himself / herself.
The reproduction based on the first condition will be described later with reference to FIGS.

  On the other hand, in the random reproduction, the reproduction condition does not pass through when reproducing the content. That is, the content is randomly acquired regardless of the situation at the place. In this case, content suitable for the current situation may be reproduced, or content completely unrelated to the current situation may be reproduced.

In random playback, unexpected content playback may give a particularly strong impression to the user. Then, the user can discover a new context or story between the current situation and the content.
The random reproduction will be described later with reference to FIGS.

  Furthermore, the present invention has an evaluation function that allows the user to be informed that the current situation matches the reproduced content. Based on this evaluation, the accuracy of the reproduction condition can be improved. In addition, by establishing a new context or story discovered by a user as a new playback condition, the discovered context or story can be shared with another user via the playback condition.

Specifically, when the reproduction of the content is started and a predetermined condition (second condition) is satisfied, the notifying unit 25 is displayed on the display panel 22.
The notifying means 25 indicates that the music and the image being reproduced can be evaluated by pressing this button on the display panel 22. Here, the second condition is, for example, a lapse of a predetermined period after the reproduction of the content is started, a timing at which the most exciting part of the music is approached, and the like.

  When the second condition is satisfied and the notifying unit 25 is displayed, the user touches the notifying unit 25 to evaluate the content being reproduced if the user determines that the content being reproduced is appropriate for the situation at that time. The information on the evaluation is output to the server 31 through communication. Then, the information is stored in the server 31 and is used at the time of the next and subsequent reproduction of the content, whereby the evaluation information can be shared among a plurality of users.

  FIG. 3 is an explanatory diagram showing the configuration of the communication system of the reproduction terminal 1 of FIG.

The playback terminal 1 is configured to be connectable to the server 31 via the base station 34 and the Internet 33.

The current status information such as the current position information detected by the current position detection unit 41 can be supplied to the server 31 by the control unit 43.
Note that the current position is not limited to being acquired by the GPS 35. For example, it can be obtained from information such as the distance from the base station 34.

  The server 31 comprises in particular a content database 32. The content database 32 stores content data, and has a table 61 (see FIG. 9) and the like necessary for content reproduction.

  FIG. 4 is a block diagram showing a configuration of the reproduction terminal 1.

  As shown in FIG. 4, the reproduction terminal 1 includes a control unit 43, which is the center of control and processing, a current position detection unit 41, a communication unit 42, a storage unit 44, an imaging unit 45, a power supply control Each of the unit 46, the operation display unit 47, and the audio input / output unit 48 is commonly connected to a system bus 49 having a plurality of lines for address, data, and control. The operation display unit 47 includes the display unit 8 and the input unit 10.

When the power of the playback terminal 1 is turned on, the power control unit 46 controls the supply of power to a circuit board or the like on which the display unit 8 and the control unit 43 in the playback terminal 1 are mounted. .
Further, at the time of charging, the charging circuit is controlled to control the start and stop of charging of the battery, the speed of charging, and the like.

The communication unit 42 performs wireless communication with the base station 34 connected to the communication network, and transmits and receives various data. The various data include file data downloaded from a download site on the Web, voice data during a voice call, mail data during mail transmission / reception, web page data during web browsing, and the like.
In the present embodiment, in particular, the communication unit 42 performs communication between the reproduction terminal 1 and the content database 32 of the server 31 with respect to the first condition, music / image data, the second condition, evaluation information, and the like. Do.

The voice input / output unit 48 including the earpiece 21 and the mouthpiece (not shown) performs input / output processing of a voice signal output to a speaker and a voice signal input to a microphone.
That is, the audio input / output unit 48 amplifies the audio input from the microphone, performs analog / digital conversion, performs signal processing such as encoding, converts the audio into digital audio data, and outputs the digital audio data to the control unit 43. .
The audio input / output unit 48 performs signal processing such as decoding, digital / analog conversion, and amplification on the audio data supplied from the control unit 43, converts the data into an analog audio signal, and outputs the analog audio signal to the speaker.
In the present embodiment, in particular, the audio input / output unit 48 outputs audio information of the music data downloaded from the server 31.

In the operation display unit 47, the display panel 22 corresponding to the display unit 8 and the touch sensor 24 corresponding to the input unit 10 are integrated.
Here, the display unit 8 is formed using, for example, an LCD or an OLED (Organic Light-Emitting Diode (organic EL)).
The display unit 8 displays an image corresponding to the video signal supplied from the control unit 43. Further, the display unit 8 displays, for example, a telephone number of a call destination at the time of wireless transmission by the communication unit 42, a telephone number of a caller at the time of an incoming call, the contents of received mail and transmitted mail, date, time, remaining battery level, and whether or not the transmission is successful And display a standby screen.
The display unit 8 may include not only the display panel 22 but also other display means. Further, the input unit 10 may include not only the touch sensor 24 but also other input means.
In the present embodiment, in particular, the notification unit 25 for the user to evaluate the content is displayed on the operation display unit 47.
When the touch sensor 24 detects that the position corresponding to the notification unit 25 has been pressed by the user, the touch sensor 24 outputs this to the control unit 43 as a user instruction.
Further, the operation display unit 47 displays the image data downloaded from the server 31 during the music reproduction period.

The imaging unit 45 is a camera including a photoelectric conversion element such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) image sensor and a control circuit therefor.
In the present embodiment, in particular, by using the imaging unit 45, the user can shoot a landscape image that matches the music being played.

The storage unit 44 stores various data used for various processes of the reproduction terminal 1. The storage unit 44 includes, for example, a computer program executed by the control unit 43, an address book for managing personal information such as a telephone number and an e-mail address of a communication partner, an audio file for reproducing a ringtone and an alarm sound, and a standby screen. Image files, various setting data, and temporary data used in the processing of the program.
In the present embodiment, in particular, the storage unit 44 stores a first condition, content data for reproduction, a second condition, a reproduction condition, evaluation information, and the like, which will be described later. Further, it stores image data captured by the imaging unit 45.

  The storage unit 44 includes, for example, a non-volatile storage device (a non-volatile semiconductor memory, a hard disk device, an optical disk device, or the like) or a randomly accessible storage device (for example, an SRAM or a DRAM).

The control unit 43 controls the overall operation of the playback terminal 1.
In other words, the control unit 43 performs various processes of the reproduction terminal 1 (such as a voice call performed through a circuit switching network, creation and transmission / reception of an e-mail, and browsing of a download site on the Internet Web). The operation of each block described above (transmission and reception of a signal by the communication unit 42, display of an image on the display unit 8, imaging processing by the imaging unit 45, and the like) is controlled so as to be performed in an appropriate procedure according to the operation.

Further, the control unit 43 includes a computer (microprocessor) that executes a process based on a program (an operating system, an application program, or the like) stored in the storage unit 44. Execute the process.
That is, the control unit 43 sequentially receives instruction codes from programs such as an operating system and application programs stored in the storage unit 44 and executes the processing.
In the present embodiment, in particular, the control unit 43 controls the entire procedure of content reproduction described later with reference to FIGS.

  FIG. 5 is a flowchart showing a processing procedure of content reproduction.

In step S01, it is determined whether or not there is a music playback instruction from the user. If there is no reproduction instruction, the process waits until there is a reproduction instruction.
Conversely, if there is a reproduction instruction, the process proceeds to step S02.
Note that the process may immediately proceed to step S02 in response to the power-on of the playback terminal 1 without receiving the user's music playback instruction. Here, as a method of turning on the reproduction terminal 1 by the user, for example, the user may operate the operation display unit 47 of the reproduction terminal 1 or the like.

In step S02, the current status information of the current playback terminal 1 is detected. Specifically, the control unit 43 detects the current situation information from the GPS 35 and the server 31 via the communication unit 42 and the current position detection unit 41.
The current situation information is geographic information such as location, weather / temperature, road conditions, seasonal information such as season and time, and information related to the traveling of the vehicle such as lights, vehicle speed, and parking information.
Among the geographic information, the information on the location is detected from the GPS 35 via the current position detection unit 41 as information on the latitude and longitude.
In addition, information on weather / temperature is obtained from the base station 34 via the communication unit 42.
Further, road conditions and the like are acquired from the GPS 35 or the base station 34 via the current position detection unit 41 or the communication unit 42. Note that the road condition information is information such as the congestion state of a running road and whether or not the vehicle is running on an expressway. Further, information such as the distance to the destination and landmarks near the travel may be included.
The temporal information can be obtained from the date and time information of the timer unit included in the control unit 43 of the playback terminal 1.
The information related to the traveling of the vehicle is acquired via the communication unit 42 from information held by an ECU (Electronic Control Unit) installed in the vehicle on board.
When step S02 is performed, the process proceeds to step S03. If there is no step S03, the process proceeds to step S04.

In step S03, it is determined whether or not to reproduce the content at random. Specifically, a random display option is displayed on the operation display unit 47, and the selection is determined by the user selecting this random display.
The control unit 43 determines whether or not there is a random reproduction instruction from the user. If there is a random reproduction instruction, the procedure shifts to procedure B (random reproduction) (described later). If there is no random reproduction instruction, the procedure goes to step S04. Transition.
If random reproduction is not performed depending on the user's selection, step S03 may be omitted.

Next, in step S04, the control unit 43 determines whether the current status information obtained in step S02 satisfies the first condition stored in the storage unit 44.
Specifically, the control unit 43 collates the first condition with the current situation information, and determines whether or not the first condition is satisfied.
If the first condition is satisfied in step S04, the process proceeds to processing A (reproduction based on the first condition). If the first condition is not satisfied, that is, if there is no reproduction condition, the process proceeds to processing B (random reproduction).
Note that the first condition and the current situation information may not be completely matched, but may be determined to be matched.

FIG. 6 is an explanatory diagram of the process of comparing the current situation information with the first condition.
As shown in FIG. 6, for example, when each attribute of each category of the acquired current situation information is “winter, night, fine, city center”, the first condition is “winter, night, fine, city center”. , It is determined that the current status information matches the first condition.
Note that the first condition and the current situation information may not be completely matched, but may be determined to be matched.
As described above, when there is a suitable condition, it is determined that the first condition is satisfied, and the process shifts to processing A. If there is no suitable condition, it is determined that the first condition is not satisfied, and the process shifts to processing B.
The determination as to whether or not the current situation matches the first condition is not limited to the method shown in FIG. 6 and can be determined by various methods.

<Reproduction based on the first condition>
FIG. 7 is a flowchart showing the procedure of the process A (in the case of reproduction based on the first condition). In the reproduction based on the first condition, the control unit 43 executes the process A following the process shown in FIG.

  In step S05, the reproduction terminal 1 supplies the current status information detected in step S02 to the server 31 via the communication unit 42 (communication output). When step S05 is performed, the process proceeds to step S06.

  In step S06, the server 31 acquires the current situation supplied (communication input) in step S05. When step S06 is performed, the process proceeds to step S07.

In step S07, the server 31 determines the most appropriate content for the acquired current situation information. At this time, the content is determined as a series of sets including not only the music data DATA and the image DATA but also the second condition and the reproduction condition associated therewith. Note that the playback condition at this time is the playback condition that is determined to match the first condition or to be the closest among the playback conditions stored in the server 31. Then, the reproduction condition is corrected in step S22 described later.
When step S07 is performed, the process proceeds to step S08.

This process will be described with reference to FIG. 6. If each attribute of each category of the acquired current situation information is “winter, night, sunny, city center”, the reproduction condition C is “winter, night” ,-, Downtown "and thus the highest matching rate, the song" Christmas night "is selected.
The selection of such music is not limited to the method as shown in FIG. 6, and can be determined by various methods.

  In step S08, the server 31 supplies (communications output) the content data determined in step S07 to the reproduction terminal 1 together with the related second condition. When step S08 is performed, the process proceeds to step S09.

In step S09, the reproduction terminal 1 acquires the content data and the second condition from the server 31. The control unit 43 causes the storage unit 44 to store the content data obtained via the communication unit 42.
When step S09 is performed, the process proceeds to step S10.

In step S10, the reproduction terminal 1 starts reproducing the content data. The control unit 43 causes the speaker of the sound input / output unit 48 to output sound and causes the display unit 8 of the operation display unit 47 to display an image.
When step S10 is performed, the process proceeds to step S11.

In step S11, the reproduction terminal 1 determines whether the second condition is satisfied.
As described above, the second condition is, for example, that a predetermined period has elapsed since the reproduction of the content was started, or the timing at which the musical piece reached the most exciting point, and the display of the notification means 25 is permitted. Is the condition for
Specifically, the control unit 43 makes the determination with reference to the second condition stored in the storage unit 44 and associated with the music currently being reproduced. When the control unit 43 determines that the second condition is satisfied, the process proceeds to step S12. When the control unit 43 does not determine that the second condition is satisfied, the process returns to continue the reproduction, and repeats step S11 until it is determined that the second condition is satisfied.

In step S12, in the reproduction terminal device 1, the control unit 43 causes the display unit 8 of the operation display unit 47 to display the notification unit 25.
When step S12 is performed, the process proceeds to step S13.

In step S13, it is determined whether the evaluation has been performed. The user can input an evaluation for the content being reproduced by using the notification means 25 displayed in step S12.
When an evaluation is input from the input unit 10 by the notification unit 25, the control unit 43 determines that an input has been made, and supplies this evaluation information to the server 31 via the communication unit 42. It should be noted that the evaluation information may include not only the information on the presence / absence of the evaluation but also information on the evaluated timing and the like.
If the evaluation has been performed, the process proceeds to step S21. If the evaluation has not been performed, the process proceeds to step S14.

Step S14 is a process of hiding the notification means 25 when the evaluation by the notification means 25 is not performed in step S13. When a predetermined period elapses from the content reproduction start time, the control unit 43 determines that a time-out has occurred, and stops displaying the notification unit 25.
The predetermined period may be a predetermined period from the start of the reproduction, or may be a predetermined period from the start point of the most exciting part of the music. In any case, a period that does not exceed the reproduction end point of the music can be set in advance.
If the control unit 43 determines that a time-out has occurred, the process A ends. If the control unit 43 does not determine that a timeout has occurred, the process returns to step S13 to repeat the subsequent processing.
When the reproduction of the content ends, the process returns to step S02. When the user performs the operation of stopping the reproduction, all the processes are ended.

Step S21 is a process in which the server 31 acquires the evaluation information supplied from the playback terminal 1 when the evaluation by the notification unit 25 is performed in step S13. The server 31 acquires evaluation information via the Internet 33 or the like.
When step S21 is performed, the process proceeds to step S22.

  In step S22, a process for correcting the reproduction condition is executed using the evaluation information acquired in step S21. Specifically, the server 31 changes the reproduction condition stored in the content database 32 based on the evaluation information. Alternatively, the weight of the reproduction condition is changed. Specifically, the weight of the reproduction condition for which the evaluation information has been obtained is increased.

Conversely, the weight of the content for which the evaluation information has not been acquired may be reduced. Specifically, if the evaluation information has not been acquired by the time when the notification unit 25 is not displayed or the music ends, the information is supplied to the server 31 as the evaluation unacquired information. In this case, it is determined that the evaluation is not obtained when the evaluation is low.
By doing so, it is possible to improve the chance of playing back unplayed or new content. In other words, by giving weights to the playback conditions to give priority to the playback, the first rank is “played, evaluated”, the second rank is “unplayed”, and the third rank is “played, no evaluation”. You can listen to the songs you've rated again in the same place. In addition, it is possible to increase the chances of listening to a new song instead of listening again to a song that has not been evaluated before and has a low impression.
When step S22 is executed, the server 31 ends the process A.

<Random playback>
FIG. 8 is a flowchart showing the procedure of the process B (in the case of random reproduction). In the random playback, the control unit 43 executes the process B following the process shown in FIG. Process B is a process in which content data is reproduced randomly without using the first condition. In the procedure shown in FIG. 5, if the user selects random playback in step S03, or if it is determined in step S04 that the first condition is absent, the process shifts to process B and S105 is executed. Hereinafter, the process B will be described with reference to FIG.

  In step S105, the reproduction terminal 1 supplies the current situation information detected in step S02 to the server 31 via the communication unit 42 (communication output). When step S105 is performed, the process proceeds to step S106.

  In step S106, the server 31 acquires the current situation information supplied (communication input) in step S105. When step S106 is performed, the process proceeds to step S107.

  In step S107, the server 31 randomly selects and determines the content. At this time, the content is determined as a series of sets including not only the music data DATA and the image DATA but also the second condition and the reproduction condition associated therewith. This reproduction condition is corrected in step S122 described later.

The difference from the first embodiment is that the first condition is not interposed. This point will be described again with reference to FIG.
In the first embodiment, the reproduction condition C that matches the first condition is always determined. On the other hand, in the second embodiment, if the user selects random reproduction in step S02, the reproduction conditions A to C Under the same conditions, one of the three is randomly determined. If the first condition is not satisfied in step S04, the reproduction conditions A and B are regarded as the same reproduction condition, and one of the two reproduction conditions is randomly determined.
When step S107 is performed, the process proceeds to step S108.

In step S108, the server 31 supplies (communications output) the content data determined in step S107 to the reproduction terminal 1 together with the related second condition.
When step S108 is executed, the process moves to step S109.

In step S109, the reproduction terminal 1 acquires the content data and the second condition from the server 31. The control unit 43 causes the storage unit 44 to store the content data and the like acquired via the communication unit 42.
When step S109 is performed, the process proceeds to step S110.

In step S110, the reproducing terminal 1 starts reproducing the content data. The control unit 43 causes the speaker of the sound input / output unit 48 to output sound and causes the display unit 8 of the operation display unit 47 to display an image.
When step S110 is performed, the process proceeds to step S111.

  In step S111, the reproduction terminal 1 determines whether the second condition is satisfied. Specifically, the control unit 43 makes the determination with reference to the second condition stored in the storage unit 44 and associated with the currently reproduced music. When the control unit 43 determines that the second condition is satisfied, the process proceeds to step S112. When the control unit 43 does not determine that the second condition is satisfied, the process returns to continue the reproduction, and repeats step S111 until it is determined that the second condition is satisfied.

In step S112, in the reproduction terminal device 1, the control unit 43 causes the display unit 8 of the operation display unit 47 to display the notification unit 25.
When step S112 is performed, the process proceeds to step S113.

In step S113, it is determined whether the evaluation has been performed. The user can input an evaluation for the content being reproduced by using the notification means 25 displayed in step S112.
When an evaluation is input from the input unit 10 by the notification unit 25, the control unit 43 determines that an input has been made, and supplies this evaluation information to the server 31 via the communication unit 42. It should be noted that the evaluation information may include not only the information on the presence / absence of the evaluation but also information on the evaluated timing and the like.
When the evaluation has been performed, the process proceeds to step S121. If the evaluation has not been performed, the process proceeds to step S114.

Step S114 is a process of hiding the notification unit 25 when the evaluation by the notification unit 25 is not performed in step S113. When a predetermined period elapses from the content reproduction start time, the control unit 43 determines that a time-out has occurred, and stops displaying the notification unit 25.
The predetermined period may be a predetermined period from the start of the reproduction, or may be a predetermined period from the start point of the most exciting part of the music. In any case, a period that does not exceed the reproduction end point of the music can be set in advance.
If the control unit 43 determines that a timeout has occurred, the process B ends. If the control unit 43 does not determine that a timeout has occurred, the process returns to step S113 to repeat the subsequent processing.
When the reproduction of the content ends, the process returns to step S02. When the user performs the operation of stopping the reproduction, all the processes are ended.

Step S121 is a process in which the server 31 acquires the evaluation information supplied from the playback terminal 1 when the evaluation is performed by the notification unit 25 in step S113. The server 31 acquires evaluation information via the Internet 33 or the like.
When step S121 is performed, the process proceeds to step S122.

  In step S122, a process of creating a reproduction condition as the first condition is executed using the evaluation information acquired in step S121. Specifically, the server 31 associates the content stored in the content database 32 as a first condition. When step S122 is executed, the process B ends.

  FIG. 9 shows a table 61 provided in the database. Music data and image data, which are music sound contents, are stored in association with one music name or music ID. Further, the second condition and the reproduction condition described above are stored in association with each music.

<Other embodiments>
During the reproduction of the content, the user may be configured to be able to upload a landscape photograph or the like matching the music being reproduced.
Specifically, after step S10 or step S110, the image data stored in the storage unit 44, such as the image captured by the imaging unit 45 of the playback terminal 1, is transmitted to the communication unit 42 during the period until the playback ends. Is uploaded to the server 31 via the.
At the time of uploading, the current status information detected by the current position detection unit 41 is simultaneously uploaded.
The server 31 regards the acquisition of the image data and the current status information as the acquisition of the evaluation information in step S21 or step S121, and executes the subsequent processing. The reason that the user actively uploads the image data is considered to be that the user has evaluated that the music and the situation of the place match.

  Further, it may be so arranged that sample data of a music piece having a reproduction condition close to the first condition is reproduced and the music piece can be purchased. In this case, it is conceivable to provide a music purchase procedure after the evaluation is performed in step S13.

  <Effect>

  According to the present invention, since the playback terminal 1 can determine the music to be played based on the latest current situation information, the user can automatically listen to the music that matches the situation at the place. Further, since the reproduction terminal 1 stores not the actual content data but only the first condition for determining the content data in the storage unit 44, the load on the storage unit 44 can be reduced.

  Further, even when there is no playback condition that meets the first condition, the playback terminal 1 can randomly acquire music and images.

  Furthermore, the playback terminal 1 of the present invention allows the user to evaluate the content, so that the user can not only passively receive the music, but also express his / her preference.

  In addition, since the reproduction condition can be corrected based on the evaluation information evaluated by the user, the accuracy of matching the reproduced content with the situation at that place can be improved.
