Description

  The present invention relates to an information processing device, an information processing method, and a program, and more particularly, to an information processing device, an information processing method, and a program that allow a predetermined amount of data to be easily transmitted.

  In recent years, audio players equipped with flash RAM (Random Access Memory) and HDD (Hard Disk Drive) for storing music data (music data) have become widespread. In such an audio player, the user rips (copies) music data recorded on a CD (Compact Disk) to a personal computer (PC) connected to the audio player, or receives music data from the Internet or the like. Download and store music data on PC. Then, the user copies the music data from the PC to the audio player via USB (Universal Serial Bus) or the like, and causes the audio player to play back the music corresponding to the music data.

  For example, a user copies desired music data from a PC to a small portable audio player and carries the portable audio player, so that the user can handle the music data copied from the PC at a desired location (for example, outdoors). I can listen to music.

  For example, when the audio player includes an HDD (Hard Disk Drive) having a storage capacity of about 20 GB, the audio player can record music data recorded on several hundred CDs. Therefore, generally, such an audio player can record all music data recorded on the PC. As a result, the user does not need to select music data to be stored in the audio player from music data recorded on the PC, and can easily record music data in the audio player.

  However, if music data is already recorded in the audio player, the free space of the HDD will be less than 20 GB, so it is difficult to record all the music data recorded on the PC in the HDD of the audio player. It may become.

Therefore, when a music playback device such as an audio player transmits the free space of the storage unit for storing music data to the PC, and the free space is less than the capacity of the music data to be transmitted, the PC stores the audio player. There is a music data transfer recording method for erasing music data stored in the section (see, for example, Patent Document 1).

In the storage unit of the audio player, it is difficult to store music data exceeding the storage capacity of the storage unit.

  For example, when the storage capacity of the HDD of the audio player is about 256 MB, it is difficult for the audio player to record music data of, for example, 5 GB (about 200 CD music data) having a capacity of 256 MB or more.

  Accordingly, the user needs to select music data having a capacity within the storage capacity of the HDD of the audio player from the music data stored in the PC as a transmission target. For example, music data stored in a PC is generally organized into a library for each CD corresponding to the music data or for each playlist created by the user. Therefore, the user selects a CD or playlist corresponding to the music data to be transmitted according to the storage capacity of the HDD of the audio player, and among the music data libraryd in the CD or playlist, It is necessary to select a song name or the like corresponding to the desired song data.

  As a result, the user's operation becomes complicated, and in particular, it is difficult for a user such as an elderly person unaccustomed to the operation to understand the operation.

  FIG. 4 shows an example of a list stored in the list storage unit 74 of FIG.

  In the list storage unit 74 of FIG. 4, each list is classified into a genre list group 91, an artist list group 92, an initial list group 93, a mood list group 94, and a playlist group 95 for each corresponding category. It is memorized separately.

  The genre list group 91 is a collection of music ID lists of music data classified based on the genre of related data, with the category as a genre. The artist-specific list group 92 is a collection of song ID lists of song data classified based on the artist of the related data, with the category as an artist. The initial list 93 is a collection of song ID lists of song data classified based on the artist or song title initial of the related data, with the category as the artist or song title initial.

  The mood-specific list group 94 is a collection of song ID lists of song data classified based on the mood of related data, with the category as a mood. The playlist group 95 is a collection of lists created based on the related data and the operation of the input unit 36 of the music server 12 by the user. Specifically, for example, the extraction unit 72 uses the related data extracted from the song data stored in the song data storage unit 71 to obtain information related to the song such as a song name and artist name of the music server 12. This is supplied to the output unit 37 and displayed.

  The user classifies the music by operating the input unit 36 of the music server 12 while selecting information related to the music displayed on the output unit 37 of the music server 12 and selecting the music title of the music, for example. The management unit 73 classifies the music based on the song name of the related data and the user's song name selection operation with the category selected by the user, and a list of song IDs corresponding to the song is set as the playlist group 95. The data is stored in the list storage unit 74.

  The genre list group 91, the artist list group 92, the initial list group 93, the mood list group 94, and the play list group 95 are divided by predetermined capacity.

  Next, a first method for creating a list of the genre list group 91 of FIG. 4 will be described with reference to FIGS. In the following, it is assumed that there are two genres, pop and classic, and a song ID with a song ID i (i is a positive number) is represented as a song ID #i. In the following, for convenience of explanation, the music data capacity is increased to several tens MB or several hundreds MB, but in reality, the music data capacity is about several MB (for example, 5 MB). Furthermore, in FIG. 5 and FIG. 6, the management part 73 shall divide music data for every capacity | capacitance of 256MB.

  When the related data is supplied from the extraction unit 72 of FIG. 3, the management unit 73 creates a list based on the genre and music data capacity of the related data. For example, when the related data includes song # 1, genre pops, and 128 MB of song data capacity, the management unit 73 creates a list 211 that is a list of song IDs corresponding to song data whose genre is pops, The data is stored in the list storage unit 74. Then, since the music data capacity included in the related data is 128 MB, which is less than 256 MB, the management unit 73 registers music # 1 associated with the music data capacity of 128 MB in the list 211.

  When the music data capacity included in the related data is 256 MB or more, for example, the management unit 201 does not register the music ID corresponding to the music data capacity in the list 211.

  Next, when related data including music # 2, genre pops, and 120 MB of music data capacity is supplied from the extraction unit 72, the management unit 73 is registered in the list 211 corresponding to the genre pops. It is determined whether the total value of the music data capacity of 128 MB corresponding to music # 1 and the music data capacity of 120 MB corresponding to music # 2 is less than 256 MB, and the total value is less than 256 MB at 248 MB Therefore, the song # 2 associated with the song data capacity of 120 MB is registered in the list 211.

  After that, when related data including music # 3, genre pops, and 56 MB of music data capacity is supplied from the extraction unit 72, the management unit 73 registers the music registered in the list 211 corresponding to the genre pops. The sum of 248 MB (= 128 MB + 120 MB) of the music data capacity of the music data corresponding to # 1 and music # 2 and 56 MB of the music data capacity of the music data corresponding to music # 3 is 256 MB. Since the total value is 304 MB of 256 MB or more, a list 212 that is a list of music IDs corresponding to music data whose genre is pops is newly created and stored in the list storage unit 74. Remember.

  Then, since the music data capacity included in the related data is 56 MB, which is less than 256 MB, the management unit 73 registers music # 3 associated with the music data capacity of 56 MB in the list 212.

  Next, when the extraction unit 72 supplies music # 4, genre classic, and related data including 75 MB of music data capacity, the management unit 73 lists music IDs corresponding to genre classic music data. The list 213 is created and stored in the list storage unit 74. Then, since the music data capacity included in the related data is 75 MB which is less than 256 MB, the management unit 73 registers music # 4 associated with the music data capacity of 75 MB in the list 213.

  As described above, when related data including music # 1 to music # 4 is sequentially supplied from the extraction unit 72, the lists 211 to 213 are stored in the list storage unit 74 as the genre-specific list group 91. .

  Thereafter, when music data to which music data # 5, genre pops and related data including 74 MB of music data capacity are added is newly stored in the music data storage unit 71, the extraction unit 72 reads the music data. The related data is extracted from the data and supplied to the management unit 73. Of the lists 211 and 212 corresponding to the pops of the genre, the management unit 73 has 56 MB of the music data capacity corresponding to the music # 3 registered in the latest list 212 and the music data capacity corresponding to the music # 5. It is determined whether the total value of 74 MB is less than 256 MB. Since the total value is 130 MB, which is less than 256 MB, as shown in FIG. To the list 211.

  That is, when new music data is stored in the music data storage unit 71, the management unit 73 sets the music ID corresponding to the music data to the genre of the music data already stored in the list storage unit 74. In the latest corresponding lists 211 to 213, the song data capacity corresponding to the song IDs registered in the lists 211 to 213, and the song data capacity corresponding to the song data newly stored in the song data storage unit 71, The music ID corresponding to the music data is added and registered until the sum becomes 256 MB or more.

  Next, a list creation process in which the music server 12 of FIG. 3 creates the lists 211 to 213 of the genre list group 91 by the first creation method will be described with reference to FIG. This list creation process is started, for example, when music data is supplied from the EMD server 11 or the disk 15 to the music data storage unit 71.

  In step S <b> 101, the extraction unit 72 extracts related data that has not yet been extracted from the music data stored in the music data storage unit 71 and supplies the extracted data to the management unit 73.

  After the processing in step S101, the process proceeds to step S102, and the management unit 73 determines the genre included in the related data supplied from the extraction unit 72 in step S101, and proceeds to step S103.

  In step S <b> 103, the management unit 73 determines whether or not the list storage unit 74 stores the music ID lists 211 to 213 corresponding to the genre determined in step S <b> 102 as the genre list group 91. For example, when the related data supplied from the extraction unit 72 in step S101 includes genre pops, the management unit 73 stores the music ID list 211 or 212 corresponding to the genre pops in the list storage unit 74. Determine whether or not.

  In step S103, when it is determined that the music ID lists 211 to 213 corresponding to the genre determined in step S102 are stored, the process proceeds to step S104, and the management unit 73 selects the latest one of the lists 211 to 213. It is determined whether the sum of the music data capacity registered in the lists 211 to 213 and the music data capacity included in the related data supplied in the immediately preceding step S101 is equal to or greater than a predetermined capacity.

  For example, when the lists 211 to 213 shown in FIG. 5 are stored in the list storage unit 74, related data including song # 5, genre pops, and song data capacity of 74 MB is supplied in the previous step S101. The management unit 73 selects 56 MB which is the music data capacity registered in the latest list 212 among the lists 211 and 212 corresponding to the genre pops, and the music included in the related data supplied in step S101. It is determined whether or not the sum of the data capacity and 74 MB is a predetermined capacity (for example, 256 MB) or more.

  On the other hand, if it is determined in step S103 that the music ID lists 211 to 213 corresponding to the genre determined in step S102 are not stored, or the music registered in the latest lists 211 to 213 in step S104. When it is determined that the sum of the data capacity and the music data capacity included in the related data supplied in the immediately preceding step S101 is greater than or equal to a predetermined capacity, the process proceeds to step S105, and the management unit 73 performs the process in step S102. New lists 211 to 213 corresponding to the discriminated genre are created and supplied to the list storage unit 74 as a genre-specific list group 91 to be stored therein.

  After the process of step S105, the process proceeds to step S106, and the management unit 73 sets the music list ID associated with the music data capacity included in the related data supplied in the previous step S101 to the new list 211 created in step S105. To 213.

  In step S104, the sum of the music data capacity registered in the latest lists 211 to 213 and the music data capacity included in the related data supplied in the immediately preceding step S101 is not greater than a predetermined capacity. If it is determined, the process proceeds to step S107, and the management unit 73 registers the music ID associated with the music data capacity included in the related data supplied in the immediately preceding step 1 in the latest list 211 to 213.

  For example, among the lists 211 and 212 corresponding to the pops of the genre, the music corresponding to the song # 5 included in the related data supplied in step S101 and 56 MB that is the song data capacity registered in the latest list 212 If the sum of the data capacity and 74 MB is not greater than (or less than) a predetermined capacity (for example, 256 MB), as shown in FIG. 6, the latest list 212 is associated with a music data capacity of 74 MB. ID is registered.

  After the processing of step S106 or step S107, the process proceeds to step S108, and the management unit 73 determines whether or not the song IDs corresponding to all the song data stored in the song data storage unit 71 are registered in the lists 211 to 213. If it is determined that the music IDs corresponding to all the music data are not registered in the lists 211 to 213, the process returns to step S101 and the above-described processing is repeated.

  On the other hand, if it is determined in step S108 that the song IDs corresponding to all the song data are registered in the lists 211 to 213, the process ends.

  As described above, in the first creation method, the music data stored in the music data storage unit 71 based on the related data supplied from the extraction unit 72 has a predetermined music data capacity corresponding to the music data. Lists 211 to 213 in which the music IDs of the divided music data are registered are created. Therefore, the management unit 73 reads out the music IDs registered in the lists 211 to 213, supplies the music IDs to the acquisition unit 76, and transmits the music data corresponding to the music IDs to the PD 14, thereby causing the PD 14 to have a predetermined capacity. Music data can be easily transmitted.

  Next, a second creation method in which the management unit 73 creates the genre list group 91 will be described with reference to FIGS.

  In the second creation method, the management unit 73 creates an all-music list for registering related data corresponding to all the song data stored in the song data storage unit 71 supplied from the extraction unit 72.

  For example, the management unit 73 creates the entire music list 230 shown in FIG. In FIG. 8, it is assumed that music data corresponding to music # 1 to # 5 is stored in the music data storage unit 71. Therefore, related data including music # 1 to music # 5 is registered in the all music list 230 of FIG.

  The management unit 73 creates the genre list group 91 of FIG. 4 based on the related data registered in the all music list 230.

  Next, a list creation process in which the music server 12 creates the genre-specific list group 91 by the second creation method will be described with reference to FIG. This list creation process is started, for example, when music data is supplied from the EMD server 11 or the disk 15 to the music data storage unit 71.

  In step S <b> 121, the extraction unit 72 (FIG. 3) extracts related data added to the music data from all the music data stored in the music data storage unit 71 and supplies the related data to the management unit 73.

  In step S122, the management unit 73 creates an all-music list 230 (FIG. 8) based on the related data supplied in step S121, and proceeds to step S123.

  In step S <b> 123, the management unit 73 shuffles the related data including the music ID registered in the all music list 230. Then, for example, the management unit 73 sequentially reads related data registered in the all music list 230 from the top, sets the music ID associated with the music data capacity included in the read related data as a registration target, and step S124. Proceed to

  In steps S124 to S129, the management unit 73 registers, in the lists 211 to 213, music IDs associated with the music data volumes to be registered in step S123.

  Since the processing of steps S124 to S129 is the same as the processing of steps S102 to S107 in FIG. 7, detailed description thereof is omitted.

  In step S <b> 130, the management unit 73 determines whether or not a music ID associated with a music data capacity included in all related data in the all content list 130 is registered.

  In step S130, when it is determined that the music ID associated with the music data capacity included in all the related data in the all content list 130 is not registered, the management unit 73 performs the processes of the previous steps S124 to S129. Next to the related data including the music IDs registered in the lists 11 to 213, the music ID associated with the music data capacity of the related data registered in the all music list 230 is set as the registration target, and the process returns to step S124, and the above-described processing is performed. Repeat the process.

  On the other hand, if it is determined in step S130 that the song ID associated with the volume of the song data included in all the related data in the all content list 130 is registered, the process ends.

  In addition, in FIGS. 5 to 9 described above, the method of creating the list in the lists 211 to 213 of the genre list group 91 has been described. However, the artist-specific list group 92, the initial list group 93, the mood list group 94, Similarly, the lists 211 to 213 of the playlist group 95 are also created.

  Next, a transmission process in which the music server 12 in FIG. 3 transmits music data to the PD 14 will be described with reference to FIG. Note that this transmission process is started, for example, when the music server 12 detects the connection of the PD 14.

  In step S151, the transmission unit 77 of the music server 12 transmits data for checking whether the PD 14 is normally connected via the network 13 to the PD 14 (network authentication).

  In step S171, the communication unit 39 of the PD 14 receives data transmitted from the transmission unit 77 via the network 13 in step S151, and proceeds to step S172.

  In step S172, the communication unit 39 of the PD 14 transmits data indicating that the PD 14 is normally connected to the music server 12 to the music server 12 via the network 13 (PD connection authentication). .

  After the process of step S151, it progresses to step S152, the receiving part 75 of the music server 12 receives the data transmitted from PD14 by step S172, and progresses to step S153.

  In step S153, the transmission unit 77 of the music server 12 sends data requesting the category corresponding to the music data to be transmitted to the PD 14 and the capacity information indicating the capacity of the music data via the network 13 to the PD 14. The process proceeds to step S154.

  After the processing in step S172, the process proceeds to step S173, and the communication unit 39 of the PD 14 receives the data transmitted from the music server 12 in step S153, and proceeds to step S174.

  In step S174, the CPU 31 of the PD 14 detects the maximum capacity of music data that can be stored (accumulated) in the storage unit 38 of the PD 14, and sets the capacity as the capacity of music data to be transmitted. For example, when the maximum capacity of music data that can be stored in the storage unit 38 of the PD 14 is 256 MB, the CPU 31 of the PD 14 sets 256 MB as the capacity of music data to be transmitted.

  Note that the capacity of music data to be transmitted may be a capacity based on the operation of the input unit 36 by the user, instead of the maximum capacity of music data that can be stored in the storage unit 38 of the PD 14. For example, music data that the user likes and does not want to delete (does not want to be replaced) is designated by operating the input unit 36 of the PD 14, for example. The CPU 31 of the PD 14 sets a value obtained by subtracting the capacity of the protected music data designated by the user from the maximum capacity of music data that can be stored in the storage unit 38 of the PD 14 as the capacity of music data to be transmitted. For example, when the maximum capacity of music data that can be stored in the storage unit 38 of the PD 14 is 256 MB and the capacity of the protected music data specified by the user is 100 MB, the CPU 31 of the PD 14 sets the music data whose transmission target is 156 MB. Capacity.

  Further, the user operates the input unit 36 of the PD 14 to designate a desired music data category. The input unit 36 of the PD 14 supplies an operation signal indicating an operation from the user to the CPU 31 of the PD 14, and the CPU 31 of the PD 14 selects a user's desired category based on the operation signal of the music data to be transmitted. Category.

  After the process of step S174, the process proceeds to step S175, and the CPU 31 of the PD 14 supplies the music data volume and category to be transmitted to the communication unit 39 of the PD 14, and the communication unit 39 of the PD 14 is the transmission target. The volume and category of the music data are transmitted to the music server 12 via the communication unit 39 of the PD 14 and the network 13.

  In step S154, the receiving unit 75 of the music server 12 supplies the management unit 73 with the volume and category of the music data to be transmitted transmitted from the PD 14 in step S175, and the process proceeds to step 55.

  In step S155, the management unit 73 performs the genre-specific list group 91, the artist-specific list group 92, and the initial-specific list created by the first creation method or the second creation method described with reference to FIGS. When it is determined whether the lists 93 to 213 of the group 93, the mood-specific list group 94, and the playlist group 95 are classified by the capacity supplied from the receiving unit 75 in step S154, and are not classified The process proceeds to step S156.

  In step S156, the management unit 73 of the music server 12 performs the list creation processing shown in FIG. 7 or FIG. 9, and the list group 91 classified by genre, the list group 92 classified by artist, The lists 211 to 213 of the initial list 93, the mood list 94, and the play list 95 are created.

  If it is determined in step S155 that the data is classified by the capacity supplied from the receiving unit 75, or after the processing in step S156, the process proceeds to step S157, and the transmitting unit 77 of the music server 12 starts from the PD 14 in step S175. ACK (Acknowledgement) indicating that the volume and category of the song data to be sent has been successfully received, and data for checking whether or not the song data is ready to be received (ready) 13 is transmitted to PD 14 via step 13, and the process proceeds to step S158.

  After the process of step S175, the process proceeds to step S176, and the communication unit 39 of the PD 14 receives the ACK and data transmitted from the music server 12 in step S157, and proceeds to step S177.

  In step S177, the communication unit 39 of the PD 14 transmits data indicating that the music data is ready to be received to the music server 12 via the network 13, and the process proceeds to step S178.

  In step S158, the receiving unit 75 of the music server 12 receives the data transmitted from the PD 14 in step S177, and proceeds to step S159.

  In step S159, the management unit 73 reads predetermined lists 211 to 213 from the list storage unit 74 based on the category supplied from the reception unit 75 in step S154. For example, when a genre is supplied as a category from the reception unit 75, the management unit 73 selects one of the lists 211 to 213 in the list group 91 (FIG. 4 or FIG. 5) of the list storage unit 74. read out.

  The management unit 73 may read any one of the lists 211 to 213 in accordance with the operation of the input unit 36 of the music server 12 by the user. In this case, for example, the management unit 73 reads related data corresponding to the music ID from the music data 71 based on the music IDs registered in the lists 211 to 213, and among the related data, the song name and the like are read out. The information is displayed on the output unit 37 of the music server 12. The user selects a desired list from the lists 211 to 213 by operating the input unit 36 of the music server 12 while viewing information such as the song title displayed on the output unit 37.

  The management unit 73 supplies the music IDs registered in the read lists 211 to 213 to the acquisition unit 76. The acquisition unit 76 reads out music data corresponding to the music ID from the music data storage unit 71 based on the music ID from the management unit 73 and supplies the music data to the transmission unit 77. And the transmission part 77 of the music server 12 transmits the music data from the acquisition part 76 to PD14 via the network 13, and progresses to step S160.

  In step S178, the communication unit 39 of the PD 14 receives the music data transmitted from the music server 12 in step S159, and stores the music data in the storage unit 38 of the PD 14. The CPU 31 of the PD 14 reads (reproduces) music data stored in the storage unit 38 of the PD 14 and causes the output unit 37 of the PD 14 to output music corresponding to the music data. Thereby, the user can listen to the music corresponding to the music data stored in the music server 12 using the PD 14.

  After the process of step S178, the process proceeds to step S179, and the communication unit 39 of the PD 14 transmits an ACK indicating that the music data has been normally received to the music server 12 via the network 13, and ends the process.
