A memory card 182 is attached to the memory card drive unit 180.

  The mobile phone 100 further includes a CPU (Central Processing Unit) 110 that performs data calculation or operation control based on an externally input instruction or a condition established inside the mobile phone 100, and receives voice input and voice. A microphone 172 that outputs a signal, a speaker 174 that receives an input of an audio signal and outputs an audio corresponding to the audio signal, and an electrical signal that is arranged between the CPU 110 and the microphone 172 and the speaker 174 is an audio signal. An audio signal processing unit 170 that converts an audio signal that is input into an electrical signal, a main display 150 and a sub-display 160 that display video based on an input signal based on the operation of the CPU 110, and the CPU 110 LE that emits light based on a signal output by control D (Light Emitting Diode) 176, a data communication interface 178 for performing data communication between CPU 110 and an external information communication device via a communication line, and an oscillation operation according to a signal output by control of CPU 110 And a vibrator 184 to perform.

  CPU 110 includes a playlist generation unit 111, a playlist output control unit 112, and a writing control unit 114. The playlist generation unit 111 generates a playlist based on a song name for identifying a song stored in the flash memory 144 and an instruction input from the main operation unit 120. Preferably, the playlist generation unit 111 reads the list name and each song name associated with the list from the flash memory 144 and stores them in the RAM 146. The playlist generation unit 111 generates list data for output using the read list name and each song name, and writes it in the RAM 146.

  The playlist output control unit 112 performs processing for outputting the generated list data to the outside. Specifically, the playlist output control unit 112 gives a data write instruction to the write control unit 114. For example, the playlist output control unit 112 reads out data stored in the RAM 146 based on an instruction to the main operation unit 120 and applies the data to a recording medium (for example, the memory card 182) attached to the memory card driving unit 180. An instruction is given to the write control unit 114 to write data. The writing control unit 114 writes the list data to the recording medium based on the instruction.

The data structure of the mobile phone 100 will be described with reference to FIG. FIG. 2 is a diagram illustrating an aspect of data storage in flash memory 144. The flash memory 144 defines the operation of the mobile phone 100, the table 200 that is a playlist database, the areas 210 and 220 that store information on the music included in the playlist, the area 250 that stores the music data, and the like. And an area 260 for storing a program prepared in advance.

  The table 200 includes areas 202 to 206 for storing data. List ID (Identification) is stored in area 202. The list ID is a number for specifying a playlist including the names of one or more music pieces. The playlist name is stored in area 204. The playlist name is data for specifying a list including music. The user of the mobile phone 100 can easily recall the composition of music included in the playlist by referring to the playlist name. The list storage location is stored in area 206. The list storage location is data (for example, an address) that specifies a location where data constituting the playlist is stored. For example, the playlist with the list ID “01” is stored in the memory area specified by the address 0x1111 (area 206).

  The data stored in the areas 202 to 206 are associated with each other. Therefore, when a list ID in the area 202 is designated, a playlist name and a list storage location associated with the ID are specified.

  Regions 210 and 220 each include data constituting a playlist. Specifically, the list ID is stored in the area 212. The first music name included in the list is stored in area 214-1. The player name of the music is stored in area 216-1. Data for specifying a storage location where the music data is stored is stored in area 218-1. The data for specifying the storage location is, for example, an address on the memory area of the area 252.

  Similarly, data about the mth music is stored in the areas 214-m to 218-m. The same applies to the play list whose list ID is “02”. That is, the data about the first music is stored in areas 224-1 to 228-1. Data about the nth music piece is stored in areas 224-n to 228-n.

  In the example shown in FIG. 2, the music name, the player name, and the data for specifying the storage location are stored for each music, but other data may be further stored. For example, a type of music, a flag indicating whether or not the music data is protected may be stored.

  The area 250 stores substantial data (music data) about each music. For example, music data whose music ID is “1” is stored in the area 252. This music data corresponds to the music specified by the data in the area 254-1.

  In area 260, an operating system for controlling basic operations of mobile phone 100 is stored in area 262. A list output program that realizes processing for outputting a playlist of music is stored in area 264.

  A control structure of the mobile phone 100 will be described with reference to FIG. FIG. 3 is a flowchart showing a procedure of processing executed by CPU 110 to output a playlist. This process is realized when the user inputs an instruction to execute the output process of the playlist displayed on the main display 150.

  In step S310, CPU 110 accepts an input of a playlist display instruction based on a signal output from main operation unit 120. In step S 320, CPU 110 reads the name (area 204) of the currently existing playlist from flash memory 144 and outputs it to main display 150. The main display 150 displays a playlist list. In step S330, CPU 110 accepts an input of an instruction to select a playlist displayed on main display 150 based on an instruction to main operation unit 120. In step S340, CPU 110 accepts an input of an output destination of the selected playlist based on an instruction output from main operation unit 120. The playlist output destination includes, for example, a folder temporarily generated in the RAM 146, a memory card 182, and other external parts of the mobile phone 100. As will be described later, transmission of data via the data communication interface 178 is also included outside the mobile phone.

  In step S350, CPU 110 accepts an input of an instruction to output the selected playlist based on an operation on main operation unit 120. In step S360, CPU 110 generates data for outputting a playlist based on the instruction. Specifically, data for output is generated by the CPU 110 functioning as the playlist generation unit 111. In step S370, CPU 110 outputs the generated data to the output destination designated in step S340.

  Here, with reference to FIG. 4, the display mode of the screen in the mobile phone 100 will be described. FIG. 4 is a diagram showing a screen displayed on main display 150. The main display 150 displays a screen for outputting a playlist in accordance with a signal output from the CPU 110. The screen includes, for example, an area 410 for displaying a message, an area 420 for displaying a playlist, and an area 430 for displaying a software key for accepting an input of a selection instruction or a cancellation instruction.

  When CPU 110 executes the list output program (area 264), a process of accepting an input of a playlist selection instruction is realized (step S330). At this time, the main display 150 displays the screen shown in FIG. The user of the mobile phone 100 selects a list name displayed in the area 420 by operating a cursor movement key (not shown) included in the main operation unit 120, for example, and inputs an instruction to confirm the selection When the software key displayed in the area 430 is pressed to accept “”, the selected list name is specified as an output target. When the program having the control structure shown in FIG. 3 is executed based on the data shown in FIG. 2, output list data is first generated in the RAM 146.

  Therefore, the configuration of the list data will be described with reference to FIG. FIG. 5 is a diagram showing list data temporarily stored in RAM 146. The RAM 146 includes a list 500 generated as an output playlist. The RAM 146 includes areas 510 to 550 for storing data.

  The header of list 500 is stored in area 510. The header includes, for example, the list name of the list 500, the date and time when the list 500 was created, and the date and time when the list 500 was output. Identification data for identifying the list 500 is stored in the area 520. This identification data is, for example, a list ID stored in the flash memory 144. Alternatively, the identification data may be changeable by the user instead of the list ID that was initially used as a default. This change is realized, for example, when the user inputs characters via the main operation unit 120. The first music piece included in the list 500 is stored in the area 530-1. The player name of the music corresponding to the music name is stored in area 540-1. Similarly, the m-th song name is stored in the area 530-m. Data EOF (End of File) representing the end of list 500 is stored in area 550. Such a list 500 is output from the mobile phone 100 as a playlist.

  As described above, the mobile phone 100 according to the first embodiment of the present invention can output playlist data including a music title to the outside. This list does not include the data of the music itself. By inputting such a playlist to another portable music player, a PC, or other information processing apparatus, the information processing apparatus can acquire the name of the music that is to be played back. When the music data corresponding to the music name included in the input playlist is already stored in the information processing apparatus, music can be reproduced according to the playlist.

  In this way, since the music data itself is not taken into another information processing apparatus, the user of the information processing apparatus can enjoy the music without performing stepless replication of the data to be protected.

<Modification>
Hereinafter, modifications of the first embodiment will be described. As described above, the mobile phone 100 may be another information communication device connected via the data communication interface 178 in addition to an external storage device such as the memory card 182 as an output destination of the playlist. . In this case, CPU 110 generates data in which a destination to which a playlist is transmitted is further added as output data.

  Note that the hardware of the mobile phone according to this modification is realized by the hardware shown in the mobile phone 100. Therefore, the following description will be given with reference to the hardware.

  First, the data structure of the mobile phone according to the present modification will be described with reference to FIG. FIG. 6 is a diagram illustrating an aspect of data storage in the RAM 146 according to the present modification. The RAM 146 includes areas 610 to 650 for storing data.

  A destination address for specifying a destination location to which list 600 is transmitted is stored in area 610. The source of the list 600, that is, the source address for specifying the location of the mobile phone 100 is stored in the area 612. The list ID is stored in area 620. The first music name is stored in area 630-1. The player name of the music is stored in area 640-1. The same applies to the music after that. An FCS (Frame Check Sequence) indicating the end of data for transmission is stored in area 650.

  The data shown in FIG. 6 is generated when the user of the mobile phone 100 inputs a transmission destination address (for example, an e-mail address) as an output destination of the playlist. After such data is generated, when the user inputs an instruction to transmit a playlist, the list 600 is transferred to another information communication device (specified by the transmission destination address (area 610) via the data communication interface 178). (Not shown).

  As described above, the mobile phone 100 according to the present modification can transmit playlist data selected by the user to a designated destination. The receiver of this data can take the playlist into his / her mobile phone, PC or other information communication device. Alternatively, the recipient can transmit the playlist to the user.

  This makes it possible to acquire another person's playlist or exchange playlists. As a result, the user can acquire information on the music that other people listen to without directly inputting the music name into the mobile phone 100, so that the opportunity to acquire a new music increases. As a result, for example, exchange of music between users having a common hobby, or provision of music corresponding to the preference is easily realized for a user of a mobile phone having a specific preference.

<Second Embodiment>
Hereinafter, a second embodiment of the present invention will be described. The mobile phone according to the present embodiment is different from the first embodiment in that it has a function of acquiring a playlist from the outside. Note that the mobile phone according to the present embodiment is realized by the same hardware configuration as the mobile phone according to the first embodiment. Their functions are the same. Therefore, description thereof will not be repeated here.

  With reference to FIG. 7, CPU 110 for realizing the mobile phone according to the present embodiment will be described. FIG. 7 is a block diagram showing a configuration of functions realized by CPU 110. In addition to the configuration shown in FIG. 1, CPU 110 includes an acquisition unit 710 for acquiring a playlist from the outside, and a write control unit 720 for writing the playlist to flash memory 144.

  For example, the acquisition unit 710 drives the memory card 182 attached to the memory card drive unit 180 and reads data stored in the memory card 182. Alternatively, when the playlist is transmitted by a signal, for example, the acquisition unit 710 extracts the playlist from the signal received by the communication unit 102. The transmission of the playlist is realized by e-mail, for example. In this case, the playlist is transmitted as a file attached to the e-mail. Alternatively, the acquisition unit 710 acquires a playlist from data that has been accepted by the data communication IF 178. The acquired playlist is temporarily stored in an area secured in the RAM 146 until deletion is instructed.

The write control unit 720 writes the playlist stored in the RAM 146 in an area secured in the flash memory 144 based on a storage instruction input via the main operation unit 120 or the sub operation unit 130.

  With reference to FIG. 8, a control structure of mobile phone 100 according to the present embodiment will be described. FIG. 8 is a flowchart showing a procedure of processing executed by CPU 110 implementing mobile phone 100 according to the present embodiment to acquire a playlist.

  In step S 810, CPU 110 accepts an input of a playlist acquisition instruction based on an operation on main operation unit 120. In step S 820, CPU 110 reads playlist data from memory card 182 attached to memory card drive unit 180 and outputs the data to main display 150. The main display 150 displays a playlist based on the data. For example, the name of the playlist is displayed. In this case, when each data of a plurality of playlists is read, each name is displayed.

  In step S840, CPU 110 accepts an input of a playlist storage location selected based on an operation on main operation unit 120. This storage destination includes, for example, a folder temporarily generated in the flash memory 144 or the RAM 146.

  In step S850, CPU 110 accepts an input of an instruction to import the playlist selected in step S330 based on an operation on main operation unit 120. In step S860, CPU 110 generates data for storage using the data of the selected playlist based on the instruction. The format of the data for storage follows the data format of the playlist in the mobile phone 100, for example. In step S870, CPU 110 writes the data generated in step S860 to the designated storage location. This completes the import of the playlist from the external storage device.

  With reference to FIG. 9, a display mode of the mobile phone according to the present embodiment will be described. FIG. 9 is a diagram showing a screen displayed on main display 150 when a recording medium (memory card 182) storing a play list is attached to memory card drive unit 180. This screen includes an area 910 for displaying a message, an area 920 for displaying a list of playlists, and an area 930 for displaying a software key for accepting selection confirmation or cancellation.

  The user can select a playlist that he / she wants to import by selecting from among the playlists displayed in the area 920 using a cursor movement key (not shown) included in the main operation unit 120.

  Here, the data structure of the mobile phone according to the present embodiment will be described with reference to FIG. FIG. 10 is a diagram illustrating an aspect of storing data in the flash memory 144 after the play list is fetched. The flash memory 144 includes a table 1000 that is a playlist database and an area 230 that stores data about a newly imported playlist. A program that realizes processing for fetching a playlist is stored in area 266.

  As is apparent from the data shown in the area 202 of the table 1000, the list ID of the captured playlist is “03”. The playlist name is “jazz”. The location where the list is stored is “0x9999”. The date and time when the playlist was added is October 1, 2005. When the process of step S870 shown in FIG. 8 is executed, data included in the selected playlist is added to the flash memory 144 as shown in FIG.

  In the area 230, the storage location of the music data corresponding to the p-th music name is set to “NULL” (area 236-p). That is, the music data is not stored in the flash memory 144. In this case, in order to reproduce this music, it is necessary to acquire data from the outside. This aspect of acquisition will be described in the next embodiment.

  As described above, mobile phone 100 according to the present embodiment accepts an input of a playlist from the outside. When a music name that already has music data among the music names included in the playlist exists in the mobile phone 100, the mobile phone 100 can play music according to the playlist. In this way, the user of the mobile phone 100 can cause the mobile phone to perform playback according to a playlist created in advance without recreating a list for playing music.

  Further, since the playlist does not have the music data itself, the music data is not duplicated. Therefore, the user of the mobile phone 100 can enjoy music within the range of music data that the user has.

A result notification data generation unit 1520 that generates data for notifying the result of confirmation by the user, and transmission of music that is not stored in the flash memory 144 based on the result of confirmation by the confirmation unit 1510 and an instruction input from the outside A transmission request generation unit 1530 for generating a request. The confirmation unit 1510 confirms the presence or absence of music by, for example, comparing the music name included in the acquired playlist with the music name stored in the flash memory 144.

  With reference to FIG. 16, the control structure of the mobile phone according to the present embodiment will be described. FIG. 16 is a flowchart showing a procedure of processing executed by CPU 110 to confirm music. This process is executed, for example, when a playlist is acquired from the outside. Alternatively, it may be executed based on an operation on the main operation unit 120.

  In step S <b> 1610, CPU 110 inputs an instruction for confirming whether or not the music corresponding to the music name included in the playlist acquired from the outside based on the operation on main operation unit 120 is stored in mobile phone 100. Accept. In step S1620, CPU 110 confirms the presence of a song corresponding to the song name included in the playlist based on the instruction. This process is realized by the CPU 110 executing a search process for each song name included in the playlist, for example. A search process based on a specific key can be easily understood by those skilled in the art. Therefore, detailed description is not described here.

  In step S1630, CPU 110 determines whether or not a song corresponding to the song name exists in flash memory 144. If such a music exists (YES in step S1630), the process proceeds to step S1640. If not (NO in step S1630), the process proceeds to step S1650. In step S1640, CPU 110 generates a list of non-existing music names in RAM 146, and adds the music name to the list.

  In step S1650, CPU 110 determines whether or not the above confirmation has been completed for all song names. If the confirmation has been completed (YES in step S1650), the process proceeds to step S1670. If not (NO in step S1650), the process proceeds to step S1660.

  In step S1660, CPU 110 confirms the presence of the corresponding music for the next music name. In step S1670, CPU 110 outputs the confirmation result. The result of confirmation is performed, for example, in the form of a list of song names for which there is no song corresponding to the song name.

  FIG. 17 is a flowchart showing a procedure of processing executed by CPU 110 to download music. This process is executed following the process shown in FIG. 16, for example. Alternatively, a song name that does not exist in the flash memory 144 may be stored, and then executed when a download instruction is input to the main operation unit 120.

  In step S <b> 1710, CPU 110 accepts selection of a song name for downloading a song based on an instruction to main operation unit 120. In step S 1720, CPU 110 accepts an input of an instruction to access a site for downloading music based on an operation on main operation unit 120. Here, the site where the music is downloaded refers to a site operated by an information communication device connected to a network such as the server 1200, for example.

  In step S1730, CPU 110 starts communication processing with the site via communication unit 102. In step S1740, CPU 110 transmits information (for example, the user name of mobile phone 100, an e-mail address, etc.) identifying the music download requester to the site. Thereafter, a communication session is started between the mobile phone and the site. In step S1750, CPU 110 transmits the music transmission request and the selected music name to the site. The transmission request is realized by a command predetermined as a transmission protocol, for example.

  In step S1760, CPU 110 receives the music data from the site. In step S1770, CPU 110 stores the received music data in an area reserved in advance in flash memory 144.

  In step S1780, CPU 110 determines whether or not an instruction to end communication processing with the site has been input based on an operation on main operation unit 120. If such an instruction has been input (YES in step S1780), the process proceeds to step S1790. If not (NO in step S1780), the process proceeds to step S1782.

  In step S1782, CPU 110 executes other data communication processing with the site via communication unit 102. In step S1790, CPU 110 ends the communication process with the site by transmitting a control signal to communication unit 102.

  Here, a display mode of the mobile phone according to the present embodiment will be described with reference to FIG. FIG. 18 is a diagram showing a screen displayed on main display 15 when mobile phone 100 downloads music.

Thereafter, when the user starts communication between the mobile phone 100 and the site according to the operation of the screen displayed on the main display 150, the data of the selected music is downloaded.

  Therefore, with reference to FIG. 19, a control structure of server 1200 according to the present embodiment will be described. FIG. 19 is a flowchart showing a procedure of processing executed by CPU 1210 of server 1200 for transmitting music.

  In step S1910, CPU 1210 detects access from mobile phone 100 based on data received via communication IF 1290. In step S 1920, CPU 1210 obtains user information of mobile phone 100 (for example, a user ID registered in advance, an e-mail address of mobile phone 100, etc.) from data received via communication IF 1290. Thereby, the session between the server 1200 and the mobile phone 100 is started. The CPU 1210 stores the acquired data in an area secured in the RAM 1240 in advance.

  In step S1922, CPU 1210 acquires a music transmission request and a music name for which transmission is requested based on the received data. The acquired data is also stored in the RAM 1240. In step S1930, CPU 1210 searches the hard disk 1250 for the music based on the acquired music name. In step S1940, CPU 1210 generates data for transmission from the retrieved music data. In step S 1950, CPU 1210 transmits the data generated via communication IF 1290 to mobile phone 100. In step S1960, CPU 1210 generates billing information for billing for the transmission of music. In step S1970, CPU 1210 associates the billing information with the mobile phone user information and stores it in an area reserved in hard disk 1150 in advance.

  In step S 1980, CPU 1210 determines whether or not an instruction to end access from mobile phone 100 is detected based on the data received via communication IF 1290. If such an instruction is detected (YES in step S1980), the process proceeds to step S1990. If not (NO in step S1980), the process proceeds to step S1982. In step S1982, CPU 1210 executes processing other than music transmission (for example, processing for transmitting newly arrived music names and other information provision). In step S1990, CPU 1210 executes processing for terminating communication with mobile phone 100. When this process is executed, the session established with the mobile phone 100 is terminated.

  Operations of the cellular phone and server 1200 according to the present embodiment based on the above-described structure and flowchart will be described. When the user of mobile phone 100 selects a song name to be downloaded and inputs an instruction to access server 1200, mobile phone 100 starts communication with server 1200 (steps S1730 and S1910). When the mobile phone 100 transmits data to the server 1200 (steps S1740, S1750, S1920), the mobile phone 100 receives the music data from the server 1200 (steps S1760, S1950). When the user inputs an instruction to end communication with server 1200 (YES in step S1780, YES in S1980), communication between mobile phone 100 and server 1200 ends (steps S1790, S1990).

  As described above, mobile phone 100 according to the present embodiment confirms whether or not all the songs included in the playlist acquired from the outside are stored. When the mobile phone 100 detects that there is an unsaved music, it can acquire the data of the music.

  For example, the mobile phone 100 starts communication with an information processing apparatus that sells music data, for example, the server 1200. The mobile phone 100 transmits user information according to a predetermined agreement. The mobile phone 100 further transmits the name of the music that is desired to be transmitted (that is, purchased). The user can purchase music data from the server 1200.
