The environmental state detection unit 11 includes, for example, a GPS unit (GPS: Global Positioning System) that detects the current position of the mobile phone, a timer that counts the current time, and a calendar function that indicates the current month / day / day of the week. . In addition, by connecting to a predetermined website provided on the network via the communication unit 2 and the antenna unit 1 and acquiring weather information based on the current position and current time acquired by the GPS unit or timer, Detect current weather. The terminal device state detection unit 12 includes a case opening / closing detection sensor that detects whether the case is open or closed, and an earphone connection sensor that detects whether the earphone is connected. The user state detection unit 13 detects the current position every specified time and calculates the moving speed.

  The program memory 5 generates a communication program 21 for performing wireless communication with a base station and communication with a predetermined website, and a media file reproduction list stored in the database unit 6. A playback list generation program 22 for playback, a playback device state management program 23 for managing a playback device state, which is a device state of the mobile phone when each media file is played back, and a media file playback A media playback program 24, which is media playback means, is stored.

  The database unit 6 stores a property database 31 that stores properties that are additional information of each media file, and a playback device that stores the playback device state detected by the device state detection unit 4 during playback of each media file. A state database 32 and a media file database 33 in which various media files such as music data and still image data are stored are stored.

  The mobile phone includes a “normal playback mode” for playing back a desired media file designated by the user, a “random playback mode” for playing back media files stored in the media file database 33 at random, and the mobile phone. There is an “automatic playback mode” for automatically selecting and playing back a media file corresponding to the situation or state. The control unit 7 controls playback of the media file stored in the media file database 33 in the playback mode selected by the user via the operation unit 3. In the “normal playback mode”, the mobile phone stores the state and state of the mobile phone when each media file is played back in the database unit 6 so that the mobile phone is in the “automatic playback mode”. It is possible to play media files that are most suitable for the situation and state of the telephone.

  Next, the media file playback operation and the playback device status database 32 creation operation will be described. FIG. 2 is a diagram schematically showing an operation flow from the media file playback instruction in the “normal playback mode” by the user until the device state database 32 at the time of media file playback is stored. In the following description, it is assumed that the media file is music data as an example.

  In FIG. 2, when an instruction to reproduce music data in the “normal reproduction mode” is given by the user via the operation unit 3 in step S <b> 21, the control unit 7 is based on the media reproduction program 24 stored in the program memory 5. Then, the music data instructed to be reproduced is reproduced while being read from the media file database 33 of the database unit 6 (step S22). At the same time, based on the playback device state management program 23 stored in the program memory 5 in step S23, the environmental state detector 11 of the device state detector 4 detects the current environmental state (season, day of the week, time zone, weather). , Location). Similarly to step S23, in step S24, the current state of the mobile phone itself (opening / closing of the casing, presence / absence of earphones) is detected by the terminal device state detection unit 12 of the device state detection unit, and in step S25, the device state The user state detection unit 13 of the detection unit 4 detects the current user state (movement speed). Then, the playback device state (hereinafter referred to as playback device state) detected in steps S23, S24, and S25 is associated with the music data being played back stored in the media file database 33, and the playback device state. Store in the database 32 (step S26).

  FIG. 3 shows a table of playback device statuses associated with each music data stored in the playback device status database 32. In FIG. 3, the items of the apparatus state at the time of reproduction of each music data (displayed by file name) include season, day of the week, time zone, weather, place, moving speed, case open / close state, and earphone connection state. For each item, classification values such as “spring”, “summer”, “autumn”, and “winter” in the season are prepared. For example, as the classification value of each item, the day of the week is “Weekday”, “Holiday”, the time zone is “Morning”, “Noon”, “Evening”, “Night”, the weather is “Sunny (including cloudy)”, “Rain” ”,“ Snow ”, moving speed“ walking ”,“ vehicle ”,“ stationary ”, housing open / closed state“ housing open ”,“ housing closed ”, earphone connection state“ earphone connected ”,“ earphone ” “No connection” is provided. Locations are classified by grouping a certain range. For example, (a) is around the user's home, (b) is around the user's work, (c) is the area the user visits for shopping, (d) is the travel destination the user has visited previously, and (e) is somewhere else , Etc.

  The numerical value described in the device status table at the time of playback of each music data indicates the number of times of playback when the corresponding music data is played back in the corresponding device status. For example, the music of the file “0001” shown in FIG. The data indicates that the season has been reproduced “10” times in “autumn” and “10” times in “winter”.

  Here, for example, when the user is in the “normal playback mode”, the file “0001” is changed to “winter”, “weekday”, “morning”, “sunny”, “stationary”, “case closed”, “no earphone connection” ”,“ (A) ”, when playing,“ Winter ”,“ Weekday ”,“ Morning ”,“ Sunny ”,“ Still ”,“ Case ”in the file“ 0001 ”in the playback device status table “1” is added to each item of “Closed”, “No Earphone Connection”, and “(a)”.

  As described above, by repeatedly performing music data playback in the “normal playback mode”, the playback device status of each music data is stored / accumulated in the playback device status database 32. For example, music data that is often heard while eating breakfast is like file “0001”, and music data that is often heard while using a mobile phone such as the Internet or mail while commuting is like file “0002” Music data used for learning a foreign language during lunch breaks at a company is like a file “0003”, and music data that is often heard while sleeping in a bed is in a playback state like a file “0004”.

  The above-described operation for creating the device state database 32 during playback has been described based on playback in the “normal playback mode”. However, as the playback mode of the mobile phone, a “designated playback mode” that performs playback in the order specified by the user is provided. In the case of playback in the “designated playback mode”, the playback device status of each music data may be stored in the playback device status database 32.

  Next, a description will be given of a playlist creation operation and a playback operation based on the playlist in the “automatic playback mode”, which is a characteristic playback operation of the mobile phone. FIG. 4 is a diagram schematically showing a playlist creation operation in the “automatic playback mode”. When reproduction by the “automatic reproduction mode” is designated by the user in step S41, the control unit 7 detects the environment of the mobile phone detected by the environmental state detection unit 11 based on the reproduction list generation program 22 in step S42. Get the status (season, day of the week, time zone, weather, location). Similarly to step S42, in step S43, the terminal device state detection unit 12 is activated and the state of the mobile phone itself detected by the terminal device state detection unit 12 (opening / closing of the casing, presence / absence of earphones) is determined. In step S44, activation control of the user state detection unit 13 is performed, and the state (movement speed) of the user of the mobile phone detected by the user state detection unit 13 is acquired. Then, the control unit 7 determines the classification value of each corresponding item from the current device status acquired in steps S42, S43, and S44, and determines the playback device status of each music data in the playback device status database 32. After comparing / searching (step S45), if the number of reproductions corresponding to the corresponding classification value is a predetermined value, for example, “5” or more, the item “number of matching items with current device state” of the corresponding music data is displayed. On the other hand, “1” is added for each match (step S46).

  For example, in the “automatic playback mode”, when the playback is instructed, the device status is “winter”, “weekday”, “morning”, “sunny”, “stationary”, “case closed”, “earphone not connected” ”,“ (A) ”, the device status database 32 at the time of reproduction is searched with the season classification value“ winter ”, and music data in which the number of reproductions of the season“ winter ”is“ 5 ”or more is detected. In this case, the control unit 7 adds “1” to the item “number of matching items with current device state” of the music data. Similarly, when searching the device status database 32 at the time of reproduction with the classification value “weekday” of the day of the week and detecting music data whose number of reproductions of “weekday” is “5” or more, the control unit 7 “1” is added to the item “number of matching items with current device state” of the music data. The item “number of matching items with current device status” is written in the playback device status database 32 as shown in FIG. 3, but a separate table may be provided.

  In this way, by adding “1” to the “number of matching items with the current device state” every time one item matches, the number of matching items of the music data of the file name “0001” is “8”. , The number of matching items of the music data of the file name “0002” is stored in the apparatus state database at the time of reproduction such as “6”, the number of matching items of the music data of the file name “0003” is “4”, etc. The “number of matching items” of all the music data is acquired. Then, the control unit 7 creates a reproduction list in which an arbitrary number of one or more music data set in descending order of the “number of matching items” is arranged. In the example of the reproduction apparatus state database shown in FIG. 3, the “number of matching items” increases in the order of “0001”, “0004”, “0002”. Based on this, the music data having the file name “0001” is reproduced as the first music, the music data having the file name “0004” is reproduced as the second music, and the music having the file name “0002” is reproduced as the third music. A playlist that plays the data is created. Based on the media playback program 24 stored in the program memory 5, the control unit 7 reads out music data from the media file database 33 in the order of the playback list and controls playback (step S47).

  The “number of matching items” indicates that the music data having a larger number matches the device status such as the current season, day of the week, time zone, location, device status, and movement speed of the mobile phone. Therefore, by creating a playlist that specifies the playback order in descending order of the “number of matching items” and controlling the playback of music data in the order of the playlist, the music data that best matches the current state of the mobile phone Playback can be performed in order.

  Note that the device state detected by the device state detection unit 4 according to the first embodiment is an example, and the environmental state is temperature, humidity, illuminance, atmospheric pressure, altitude, the terminal device state is a charging state, a phone application or a game is used. The apparatus state detection unit 4 may be configured to detect body temperature, blood pressure, pulse rate, mood, etc. as user settings such as application and manner mode, and user state, and these apparatus states may be used.

  In addition, when the number of times of reproduction is “5” or more, the “number of matching items” is incremented by “1”. However, when an item of a desired device state is specified by the user, the specified item is matched. By adding weights so that the numerical value to be added to the “number of matching items” is relatively large, music data having a device state at the time of playback that particularly corresponds to the item of the specified device state is displayed at the top of the playlist. It becomes possible to add to. Conversely, by relatively reducing the numerical value to be added to the “number of matching items”, music data having a playback device status that specifically corresponds to the specified device status item is excluded from the playlist, or subordinately. It becomes possible to.

  Also, when the number of playbacks is “5” or more, the state matches. However, the number of playbacks to be compared is adjusted according to the total number of playbacks of each media file or the total number of playbacks of the media file, In this case, the numerical value to be added may be made variable according to the number of reproductions, such as adding “1” by 1 and adding “2” by “10” or more.

  In the first embodiment, for simplification, the playback device status database 32 stores the playback device status for each media file as a classification value. For example, the date / time / minute / second is stored in the database. A method may be used in which the detected device state at the time of reproduction is directly stored in the device state database 32 at the time of reproduction by performing processing such as sorting the season, day of the week, and time zone when the reproduction list is created.

  Also, the music data having the largest number of “matching items” is played in order, but for example, music data having the largest number of “matching items” is randomly selected from the music data having the largest number of “matching items”. A function for designating the reproduction may be provided.

  In addition, although the playback device status is stored for each music data, the playback device status is stored using a playlist in which the music data playback order is described, a channel in a broadcast type service, etc. as one unit. But the same effect can be obtained.

  In the first embodiment, the present invention is applied to a mobile phone. However, the present invention is not limited to a PHS phone (Personal Handyphone System), a PDA device (Personal Digital Assistant) having a wireless communication function, Alternatively, the present invention can be applied to other portable terminal devices such as a notebook personal computer device having a wireless communication function.

Embodiment 2. FIG.
Since the configuration of the mobile phone according to Embodiment 2 of the present invention is the same as that of Embodiment 1, description thereof is omitted. In the mobile phone according to the first embodiment, music data is reproduced based on the playlist created based on the playlist generation program 22, but the second embodiment of the present invention searches for desired music data. In addition, a user creates a reproduction list by specifying a device state, and reproduces music data based on the reproduction list. Further, a list of music data of the created reproduction list is displayed, and desired music data is reproduced by editing the reproduction list.

  First, a method for a user to specify a device state in order to search for desired music data will be described. For example, suppose that a user wants to search for music data that was previously heard outside the home on a winter holiday. When the user designates “winter”, “holiday”, and “other than (a)”, which are the user's desired device states, via the operation unit 3, the control unit 7 is based on the playlist generation program 22. , “Winter”, “holiday”, “other than (a)” and the apparatus state at the time of reproduction of each music data are compared to calculate “number of matching items”.

  FIG. 5 shows a table example of the playback device status of each music data stored in the playback device status database 32 used in the second embodiment of the present invention. In descending order of the “number of matching items”, the music data with the file name “0007” is created as the first music, and the music data with the file name “0008” is created as the second music.

  Here, the control unit 7 starts the playback in the order of the playlist created as in the first embodiment by selection, or the mobile phone has music data list information in the order of the created playlist. Display a list on the display unit. When the mobile phone according to Embodiment 2 of the present invention displays a list, the display order is changed or an unnecessary music list is deleted according to the input of the operation unit 3 from the user. It has a playlist editing function that allows the playlist to be edited. The edited playlist is overwritten or newly saved. The control unit 7 starts playing the music data in the order of the edited play list.

  Further, the control unit 7 changes the number of reproductions on the apparatus state database during reproduction of the music data edited on the reproduction list by the user. For example, for music data deleted from the playback list by the user, it is possible to exclude the deleted music data from the playback list at the next search by decreasing the number of playback times. In addition, by making the numerical value of the number of playback times of music data whose playlist order has been changed by the user larger or smaller based on the order of modification, the playlist for the next search can be matched to the user's preference. It becomes possible. In addition, by providing a function that can cancel the playback of predetermined music data during playback, and by reducing the number of playback times of the canceled music data, a playlist that matches the user's preference at the next search can be similarly obtained. Easy to create.

Embodiment 3 FIG.
Since the configuration of the mobile phone according to Embodiment 3 of the present invention is the same as that of Embodiment 1, description thereof is omitted. In the mobile phone according to the first embodiment, music data is reproduced based on the reproduction list created based on the reproduction list generating program 22, but the third embodiment of the present invention searches for desired music data. In addition, a user designates a condition to create a reproduction list, and music data is reproduced based on the reproduction list. Further, a list of music data of the created reproduction list is displayed, and desired music data is reproduced by editing the reproduction list.

  First, a method for a user to specify conditions for searching for desired music data will be described. In the third embodiment, music data that is considered to be close to the condition of music data that the user wants to search is designated. The display unit displays a playback device state table for each music data stored in the playback device state database 32. It is assumed that the user wants to search for music data close to the condition of the file name “0005”. When the file “0005” is designated by the user via the operation unit 3, the control unit 7 displays “winter”, “holiday”, “daytime”, “sunny”, which are the playback device status of “0005”. , “Walk”, “case closed”, “earphone connected”, and “(a)” are extracted, and these are compared with the device state at the time of reproduction of each music data to calculate “number of matching items”.

  FIG. 6 shows a table example of the playback device status of each music data stored in the playback device status database 32 used in the third embodiment of the present invention. In descending order of “number of matching items”, music data with the file name “0005” as the first music, music data with the file name “0006” as the second music, music data with the file name “0008” as the third music Is created.

  As in the above-described second embodiment, the created playlist can be selected to start playback in the order of the playlist or be edited by the user, and if edited, the music in the order of the playlist after editing can be selected. Start playing data.

  According to the above, since music data that is close to the conditions is specified for music data to be searched for searching, it is possible to easily create a reproduction list that more suits the user's preference.

Embodiment 4 FIG.
In the first to third embodiments described above, three methods of specifying the device status to be compared have been described: the current device status, the device status designation by the user, and the file designation by the user. In the fourth embodiment, , Any two or three of these can be specified in combination. When specifying in combination, a comparison is made with the total value of the “number of matching items” for a plurality of device states.

  Further, by adding the property of the music data designated by the user to the search condition, it becomes possible to perform a search more suitable for the user's preference. The property of the music data is stored in the property database 31 by user input, or the property acquired by analyzing the header of the music data is stored.

  FIG. 7 shows an example of properties stored in the property database 31. As property items, a title name, artist name, album name, year, genre, composer, songwriter, rights holder, distributor, comment, etc. are stored in the property database 31. For example, when the user designates “genre” as “pop” via the operation unit 3, “genre” is set to “pop” from a playlist created by comparison with one or more designated device states. "0005", "0006", "0007", "0008", and "0009" are excluded. For example, when the user designates “genre” as “other than reggae” via the operation unit 3, “0006” whose “genre” is “reggae” is excluded from the reproduction list.

  Here, the operation when registering new music data will be described. In order to add music data immediately after newly registered to the reproduction list, it is necessary to set a suitable apparatus state during reproduction. In the fourth embodiment of the present invention, among the already registered music data, the apparatus state at the time of reproduction related to music data whose property is the same as or similar to the new music data is set. For example, assume that music data “0010” having the properties shown in FIG. 7 is newly registered. The control unit 7 compares the property of each music data registered in the property database 31 with the property of the new music data for each item, calculates the number of matching items, for example, by adding, and the file having the most common items of properties. In the example of FIG. 7, “0005” is searched. Then, the playback device state “0005” is extracted and stored in the playback device state database 32 as the playback device state “0010”.

  As described above, since a combination of device states based on different designation methods is used as a search condition for creating a play list, a play list more suitable for the user's preference can be created. Further, since the music data property is further added to the search condition, a search suitable for the user's preference is possible. Furthermore, when registering new music data, it is decided to use the device state during playback of already registered music data having the same / similar property, so that the new music data is also played back in the “normal playback mode”. In addition, it can be used as a search target for the “automatic playback mode”.
