Description

  The present invention relates to a music playback device including a storage unit that stores music data and a playback unit that plays back the music data stored in the storage unit.

  2. Description of the Related Art Conventionally, music playback apparatuses that automatically store music data provided by radio broadcasting have been proposed. Since this kind of music reproducing apparatus automatically stores a lot of music data, there is an advantage that it is possible to reduce time and effort of the user when collecting music data.

  However, in such a music playback device, the capacity of the storage unit is limited, so if there is not enough capacity, it is necessary to delete unnecessary music data from the collected music data.

  Here, when deleting the collected music data, the user can reproduce the collected music data one by one and delete it while checking whether or not it is his favorite music data. Conceivable. However, since such a work is a time-consuming work for the user, a music playback device that automatically deletes unnecessary music data that does not meet the user's preference is desired.

Thus, in recent years, a music playback device that automatically deletes music data has been proposed (see, for example, Patent Document 1). According to such a music playback device, the preference (degree of preference) of the user for the music data is obtained based on information added to the music data, such as the genre of the music, the storage date and time, the number of times of playback, and the obtained preference. The music data can be automatically deleted according to the degree. If such a music reproducing device is used, the user can reduce time and labor when deleting unnecessary music data.

  However, it is assumed that the user likes not only a specific genre but also music data of various genres. It is also assumed that the user prefers old or new music data regardless of the storage date. In addition, the user may play the favorite music data many times to increase the number of times of reproduction, but even if the music data is not preferred, for example, it is played many times because the reproduction order is first. Therefore, it may be possible to increase the number of reproductions. That is, it cannot be said that the preference degree obtained based on the genre, the storage date / time, and the number of reproductions appropriately reflects the user's preference.

  In addition, a music playback device that automatically deletes music data can greatly reduce the user's trouble of deleting music data, but the user likes it if the degree of preference that appropriately reflects the user's preferences is not required. The music data is also deleted. In other words, in a music playback device that automatically deletes music data, the preference level is an important parameter for specifying the music data to be deleted, and therefore, the preference level that appropriately reflects the user's preference is obtained. Is desired.

  Therefore, the present invention has been made in view of the above points, and a music playback device capable of setting a preference level more appropriately reflecting a user's preference (preference) for stored music data. The purpose is to provide.

When the reproduction period from when the reproduction is started until the predetermined operation is detected by the detection unit is equal to or greater than a threshold, the degree of preference is relatively increased. According to such a feature, the music reproducing device relatively increases the degree of preference when the reproduction period from the reproduction start to the stop is equal to or greater than the threshold. Therefore, when the playback period is equal to or greater than the threshold, the music playback device estimates that the user's preference for the music data being played is high and raises the preference, so the preference level that more appropriately reflects the user's preference is set. Can be set. Further, in the music reproducing device, the user estimates and sets the preference level from the normal reproduction operation of the music data, so that the user can easily perform the work when setting the preference level.

  The third feature of the present invention relates to the first feature, wherein the predetermined operation is an operation of playing music data different from the music data being played (an operation of pressing a skip button 193), The gist of the setting unit is to relatively increase the degree of preference when the reproduction period from the start of reproduction of the music data until the predetermined operation is detected by the detection unit is equal to or greater than a threshold value. It is. According to such a feature, the music playback device relatively increases the degree of preference when the playback period from the start of playback to playback (skip) of another music data is equal to or greater than the threshold. Therefore, when the playback period is equal to or greater than the threshold value, the music playback device estimates that the user's preference for the music data being played is high and raises the preference. Therefore, the music playback device more appropriately reflects the user's preference. Can be set. Further, in the music reproducing device, the user estimates and sets the preference level from the normal reproduction operation of the music data, so that the user can easily perform the work when setting the preference level.

  The fourth feature of the present invention relates to the second feature or the third feature, wherein the setting unit relatively increases the degree of preference when the rust portion included in the music data is reproduced within the reproduction period. It is a summary. According to such a feature, the music reproducing device relatively increases the degree of preference when the rust portion is reproduced within the reproduction period. Therefore, in the music playback device, the user increases the preference level by estimating that the user's preference is high with respect to the music data in which the rust portion, which is a characteristic part of the music, is listened to. The reflected preference can be set.

It is detected that an operation for reproducing music data has been executed. At this time, the operation detection unit 200 outputs a skip instruction signal to the reproduction control unit 220 and the setting unit 230. Here, the skip instruction signal is a signal for instructing reproduction of music data different from the music data being reproduced.

  Further, the operation detecting unit 200 detects that an operation for changing the degree of preference of the music data being played back by the user is performed when a pressing signal is input from the preference button 194 while the predetermined music data is being played back. To do. At this time, the operation detection unit 200 outputs a preference level change signal to the setting unit 230. Here, the preference level change signal is a signal for instructing the change of the preference level stored in the preference level table T1 of the storage unit 150. Note that, when the user continues to press the preference button 194 and a pressing signal is continuously input from the preference button 194, the operation detection unit 200 continues to output the preference level change signal to the setting unit 230.

  In addition, when a pressing signal is input from the delete button 195, the operation detection unit 200 detects that an operation for deleting music data stored by the user has been executed. At this time, the operation detection unit 200 outputs a deletion instruction signal to the deletion unit 240.

  The operation detection unit 200 may be configured to output the reproduction instruction signal, the stop instruction signal, the skip instruction signal, and the preference level change signal described above including the time data. In the present embodiment, the operation detection unit 200 constitutes a detection unit that detects a predetermined operation performed by the user during reproduction of music data.

  The chorus reproduction determination unit 210 determines whether or not the chorus part included in the music data being reproduced has been reproduced. Specifically, the rust reproduction determination unit 210 monitors the reproduction period of each piece of music data when the piece of music data is reproduced by the decoding processing unit 160. At this time, the rust reproduction determining unit 210 determines whether or not the reproduction period of the music data being reproduced is equal to or greater than the notified climatic timing information based on the climatic timing information notified from the reproduction control unit 220 described later. judge. Further, when the rust reproduction determination unit 210 determines that the reproduction period of the music data is equal to or longer than the climatic timing information, that is, when it is determined that the climax part of the music data being reproduced has been reproduced, the setting unit 230 Notify

  The playback control unit 220 controls playback / stop of music data. Specifically, the reproduction control unit 220 instructs the decoding processing unit 160 to reproduce music data when a reproduction instruction signal is input from the operation detection unit 200. At this time, the playback control unit 220 refers to the chorus timing table T2 of the chorus timing information storage unit 150b, reads the chorus timing information corresponding to the music data being played, and notifies the chorus reproduction determination unit 210. In addition, when a stop instruction signal is input from the operation detection unit 200, the playback control unit 220 instructs the decoding processing unit 160 to stop music data. In addition, when a skip instruction signal is input from the operation detection unit 200, the reproduction control unit 220 instructs the decoding processing unit 160 to reproduce another piece of music data.

  Based on a predetermined operation, the setting unit 230 sets a preference level indicating the degree of preference of the user in association with music data that is reproduced when a predetermined operation is detected by the operation detection unit 200. The setting unit 230 increases the relative preference when the reproduction period from the start of reproduction of music data until the operation detection unit 200 detects the user's skip operation (predetermined operation) is equal to or greater than the threshold.

  Specifically, when the reproduction instruction signal is input from the operation detection unit 200, the setting unit 230 starts a provided timer. In addition, when the skip instruction signal is input from the operation detection unit 200, the setting unit 230 stops the timer, measures a period from the start to the stop of the timer, and acquires the period as a reproduction period. In addition, the setting unit 230 determines whether or not the acquired reproduction period is equal to or greater than a threshold (predetermined period) stored in advance. When the setting unit 230 determines that the reproduction period is equal to or greater than the threshold, the setting unit 230 refers to the preference table T1 of the preference storage unit 150c, and identifies the music data ID corresponding to the music data that was reproduced immediately before. At the same time, the preference level associated with the specified music data ID is increased by one (for example, “3” to “4”) and stored in the preference level table T1. Note that when the playback instruction signal and the skip instruction signal include time data, the setting unit 230 may be configured to acquire the playback period based on the time data.

  In addition, the setting unit 230 increases the relative preference when the chorus part included in the music data is reproduced within the reproduction period. Specifically, upon receiving notification from the rust reproduction determining unit 210 that the rust portion has been detected, the setting unit 230 changes the rust detection flag from “OFF” to “ON” and stores it. And the setting part 230 will determine whether the rust detection flag memorize | stored is "ON", if a stop instruction | indication signal is input from the operation detection part 200. FIG. If the setting unit 230 determines that the rust detection flag is “ON”, the setting unit 230 refers to the preference table T1 of the storage unit 150, specifies the music data ID corresponding to the music data being reproduced, and The preference level associated with the specified music data ID is increased by one (for example, “3” to “4”), and stored in the preference level table T1 of the storage unit 150.

  The setting unit 230 increases the relative preference according to the operation period (pressing period) of the preference button pressed by the user during the reproduction of the music data. Specifically, when setting unit 230 receives a preference level change signal from operation detection unit 200, setting unit 230 starts to start a timer. And the operation detection part 200 measures the period until a preference degree change signal is no longer input, and acquires the measured period as an operation period. The setting unit 230 determines whether or not the acquired operation period is equal to or greater than a threshold value (predetermined period) stored in advance. When the setting unit 230 determines that the value is equal to or greater than the threshold value, the setting unit 230 refers to the preference table T1 of the preference storage unit 150c, identifies the music data ID corresponding to the music data being reproduced, and identifies the music data thus identified. The preference level associated with the ID is increased by two (for example, “3” to “5”) and stored in the preference level table T1. If the setting unit 230 determines that the value is not equal to or greater than the threshold, the setting unit 230 increases the preference level associated with the specified music data ID by one (for example, “3” to “4”), and sets the preference level. Store in table T1.

  The deletion unit 240 deletes the stored music data from the music data storage unit 150a based on the preference level associated by the setting unit 230. Specifically, when the deletion instruction signal is input from the operation detection unit 200, the deletion unit 240 refers to the preference level table T1 of the preference level storage unit 150c, and the preference level is less than a threshold (predetermined preference level) stored in advance. The music data ID is specified, and the music data corresponding to the music data ID is deleted from the music data storage unit 150a. Note that when the deletion instruction signal is input from the operation detection unit 200, the deletion unit 240 specifies a predetermined number of music data IDs stored in advance from lower music data IDs having a lower preference, and specifies the specified music data IDs. May be configured to delete the music data corresponding to.

(Operation of music playback device)
Next, the operation of the music playback device 1 according to this embodiment will be described. Specifically, a music data storage (recording) operation and a preference setting operation during reproduction of music data will be described.

(Music data storage operation)
First, the music data storing operation in the music playback device 1 will be described with reference to FIG. In step S10, in the music reproducing device 1, the receiving unit 110 starts receiving a broadcast audio signal. In addition, the A / D conversion unit 120 converts the audio signal received by the reception unit 110 into a digital audio signal and outputs the digital audio signal to the music detection unit 130.

  In step S12, the music detection unit 130 inputs the digital audio signal converted by the A / D conversion unit 120 and temporarily stores the digital audio signal.

  In step S14, the music detection unit 130 extracts music data included in the stored digital audio signal. In addition, the music detection unit 130 outputs the extracted music data to the encoding processing unit 140 and the chorus identification unit 300.

  In step S <b> 16, when the rust specifying unit 300 acquires the music data from the music detection unit 130, the rust specifying unit 300 specifies the timing of the rust portion in the music data.

  In step S18, the rust specifying unit 300, when specifying the timing of the rust portion, associates the climax timing information indicating the timing with the song data ID of the song data, and associates the chorus timing table T2 of the climax timing information storage unit 150b. To remember. The encoding processing unit 140 receives music data from the music detection unit 130, encodes the music data, and stores the data in the music data storage unit 150a. At this time, the encoding processing unit 140 may be configured not to store the preference level corresponding to the music data ID in the preference level table T1, or the median preference level (for example, the preference level is “ In the case of a value from “1” to “5”, an intermediate “3”) may be stored.

  In this way, in the music playback device 1, the music data is stored in the music data storage unit 150a, and the chorus timing information is stored in the chorus timing information storage unit 150b. Note that the music playback device 1 may be configured to execute the above-described operations of steps S12 to S18 when the music playback device 1 is powered on, or a storage start button (not shown) by the user. May be configured to be executed when the button is pressed.

(Music data playback operation)
With reference to FIG. 6, the reproduction | regeneration operation | movement of the music data in the music reproduction apparatus 1 is demonstrated. In step S <b> 102, the operation detection unit 200 outputs a reproduction instruction signal to the reproduction control unit 220 and the setting unit 230 when the user presses the reproduction button 191 and outputs a depression signal from the reproduction button 191. When the reproduction instruction signal is input from the operation detection unit 200, the reproduction control unit 220 instructs the decoding processing unit 160 to reproduce the music data. Upon receiving this instruction, the decryption processing unit 160 reads the music data stored in the storage unit 150. In addition, the reproduction control unit 220 reads out the climatic timing information stored in the climatic timing table T2 and notifies the rust reproduction determining unit 210 of the information.

  In step S <b> 104, the decryption processing unit 160 decrypts the read music data and outputs the decrypted music data to the D / A conversion unit 170. The D / A conversion unit 170 converts the music data decoded by the decoding processing unit 160 into an audio signal and outputs the audio signal to the speaker 180. The speaker 180 outputs the audio signal converted by the D / A conversion unit 170. In this way, the music playback device 1 starts playback of music data. At this time, the setting unit 230 and the rust reproduction determination unit 210 start the timer.

  In step S <b> 106, the rust reproduction determination unit 210 determines whether or not the climax part has been reproduced based on the rust timing information notified from the reproduction control unit 220. Specifically, the chorus reproduction determination unit 210 determines whether or not the reproduction period of the music data being reproduced is equal to or greater than the notified chorus timing information.

  In step S108, the chorus reproduction determination unit 210 notifies the setting unit 230 of this when it is determined that the reproduction period of the music data is equal to or greater than the notified chorus timing information and the chorus part has been reproduced. Also, the setting unit 230 that has received this notification changes the rust detection flag from “OFF” to “ON” and stores it.

  In step S110, the operation detection unit 200 determines whether or not the stop button 192 is pressed during reproduction of music data.

  In step S112, when a press signal is input from the stop button 192, the operation detection unit 200 determines that the stop button 192 has been pressed by the user, and outputs a stop instruction signal to the playback control unit 220 and the setting unit 230. Further, when the reproduction control unit 220 receives a stop instruction signal from the operation detection unit 200, the reproduction control unit 220 instructs the decoding processing unit 160 to stop the music data. Upon receiving this instruction, the decryption processing unit 160 stops decrypting the music data. Then, the reproduction of the music data is stopped.

  In addition, when the stop instruction signal is input from the operation detection unit 200, the setting unit 230 determines whether or not the stored rust detection flag is “ON”, and if it is “ON”, the preference table T1. The music data ID corresponding to the music data being reproduced is identified, and the preference level associated with the identified music data ID is increased by one (for example, “3” to “4”). This is set and stored in the preference table T1 (step S114).

  In step S116, the operation detection unit 200 determines whether or not the preference button 194 has been pressed during reproduction of the music data.

  In step S <b> 118, when a pressing signal is input from the preference button 194, the operation detection unit 200 determines that the preference button 194 has been pressed by the user, and outputs a preference level change signal to the setting unit 230. Further, the operation detection unit 200 continues to output the preference level change signal to the setting unit 230 when the pressing signal is continuously input from the preference button 194. In addition, when the preference level change signal is input from the operation detection unit 200, the setting unit 230 starts activation of a timer (a timer different from step S104), and indicates a period until the preference level change signal is not input. Get as.

  In step S120, the setting unit 230 sets a preference level for the music data being played based on the operation period. Specifically, the setting unit 230 determines whether or not the operation period is equal to or greater than a threshold value (predetermined period) stored in advance. When the setting unit 230 determines that the operation period is equal to or greater than the threshold, the setting unit 230 refers to the preference table T1 and specifies the music data ID corresponding to the music data being played back, and is associated with the specified music data ID. The preference level is increased by two (for example, “3” to “5”) and stored in the preference level table T1. If the setting unit 230 determines that the operation period is not equal to or greater than the threshold value, the setting unit 230 specifies the music data ID corresponding to the music data being played, and sets one preference level associated with the specified music data ID. Is set (for example, “3” to “4”) and stored in the preference table T1. Thereafter, the music reproducing device 1 returns to the operation of step S106.

  In this way, the setting unit 230 changes and sets the preference level corresponding to the music data being played back when a user operation is detected. Note that the preference level raised by the setting unit 230 is not limited to one or two, and may be configured such that three or four or the like can be raised.

  In step S122, the operation detection unit 200 determines whether or not the skip button 193 is pressed during reproduction of the music data. At this time, when the operation detection unit 200 determines that the skip button 193 has not been pressed, the music reproducing device 1 repeats the operation from step S102.

  In step S124, the operation detection unit 200 determines that the user has pressed the skip button 193 when a press signal is input from the skip button 193. At this time, the operation detection unit 200 outputs a skip instruction signal to the reproduction control unit 220 and the setting unit 230.

  In step S126, when the setting instruction 230 receives a skip instruction signal from the operation detection section 200, the setting section 230 stops the timer started in step S104, and acquires a period from the start to the stop of the timer as a reproduction period. And the setting part 230 determines whether the acquired reproduction | regeneration period is more than the threshold value memorize | stored previously. In addition, when the setting unit 230 determines that the acquired reproduction period is equal to or greater than the threshold value stored in advance, the setting unit 230 refers to the preference table T1 and specifies the music data ID corresponding to the music data that has been reproduced, and also specifies The preference level associated with the music data ID is increased by one (for example, “3” to “4”), and stored in the preference level table T1. When the playback control unit 220 receives a skip instruction signal from the operation detection unit 200, the playback control unit 220 instructs the decoding processing unit 160 to play another piece of music data. Thereafter, in the music reproducing device 1, the operations in steps S102 to S126 are repeated.

(Action / Effect)
According to the music playback device 1 according to the present embodiment, the operation detection unit 200 detects pressing of each button (predetermined operation) performed by the user during playback of music data, and the setting unit 230 detects the detected button. The preference level is set in association with the music data being played based on the type of the song. Therefore, the music playback device 1 can set the degree of preference that directly reflects the user's preference (preference) with respect to the music data being played back in association with the music data from the operation executed by the user. As described above, the music reproducing device 1 can set the degree of preference that more appropriately reflects the user's preference (preference) for the stored music data.

  In the music playback device, the setting unit 230 increases the degree of preference when the playback period from the start of playback to playback (skip) of another music data is equal to or greater than the threshold. That is, in the music playback device 1, since the user has listened to the music data for longer than the threshold value, it is estimated that the user's preference for the music data being played is high and the preference is increased, so that the user's preference is further increased. Appropriate degree of preference can be set.

  In the music playback device 1, the setting unit 230 increases the preference of the music data being played back when the chorus part is played back during the playback period. Therefore, in the music reproducing apparatus 1, since the user increases the degree of preference of the music data when he / she listens to the rust portion that is a characteristic part of the music data, the degree of preference that more appropriately reflects the user's preference can be set.

  In the music reproducing device 1, the operation detection unit 200 detects that the preference button for changing the preference level has been pressed, and transmits a preference level change signal to the setting unit 230. The setting unit 230 measures the operation period when the preference level change signal is input. If the measured operation period is equal to or greater than the threshold, the preference level is increased by two. If the operation period is not equal to or greater than the threshold, Increase the preference level by one. Therefore, since the music reproducing apparatus 1 can reflect the direct intention of the user with respect to the music data being reproduced, it is possible to set a preference level that more appropriately reflects the user's preference. Further, in the music playback device, the user sets the preference level only by pressing (long pressing) one button, so that the user can easily perform the work when setting the preference level.

  Thus, according to the music reproducing apparatus 1, the user can easily operate various buttons with one finger, and thus, for example, a car audio device that is mounted on a car and may be operated during driving. When the music reproducing device 1 is applied, it is particularly effective.

  Also, according to the music playback device 1, the preference level is set based on operations generally performed by the user at the time of playback of music data, such as playback, skip, and stop of music data, so that the user is not conscious. The preference of music data can be set. Moreover, according to the music reproducing device 1, the preference level can also be set based on an operation in which the user consciously changes the preference level, such as an operation of a user preference level button.

  Moreover, in the music reproduction apparatus 1, since the deletion part 240 deletes the music data in which the stored preference degree is less than the threshold, it is possible to reduce the deletion of the music data preferred by the user.

(Modification)
The present invention is not limited to the above embodiment, and various modifications can be made. In the above-described embodiment, the setting unit 230 is configured to increase the preference degree according to the operation period (pressing period) of the preference button 194 detected by the operation detection unit 200. Depending on the number of pressed preference buttons, the preference level may be increased.

  Specifically, in step S118 described above, the operation detection unit 200 determines that the preference level change signal is pressed when the preference button 194 is pressed once or a plurality of times by the user during the reproduction of the music data. Only to the setting unit 230. Further, when the preference level change signal is input by the number of times pressed from the operation detection unit 200, the setting unit 230 refers to the preference level table T1 and specifies the music data ID corresponding to the music data being reproduced, The preference level associated with the specified music data ID is set according to the number of times of input of the preference level change signal (for example, “3” to “5” for two times), and the preference level table is set. Store in T1.

  According to the present modification, in the music playback device 1, the operation detection unit 200 detects that the preference button for changing the preference level during music data playback has been pressed, and the preference level change signal is sent to the setting unit 230. Send. In addition, the setting unit 230 increases the preference level by the number of times according to the number of times the preference level change signal is input. Therefore, the music playback device 1 sets the preference level reflecting the direct intention of the user with respect to the music data being played back, and thus can set the preference level more appropriately reflecting the user's preference. Further, in the music playback device 1, since the user estimates and sets the preference level only by pressing one button (pressing the number of times), the user can simplify the work when setting the preference level. .
