That is, since the lyrics and linanoarts are rewritten based on the editing work by the user, the GUI unit 61 displays a return button 151 for returning them to the original lyrics and linanoarts.

  Accordingly, when the user deletes the edited additional information by mistake, the user can easily restore the original additional information by selecting the return button 151.

  Next, the operation of the embodiment of the present invention will be described in order with reference to a flowchart.

  First, content distribution processing will be described.

  For example, when distributing content to the portable device 5 via the network 2, the EMD server 3 generates the additional information 77 for the PC that can be read by the personal computer 1, and also adds the additional information for PD that can be read by the portable device 5. Information 78 is generated. The EMD server 3 describes the PC additional information 77 in a highly extensible format, describes the PD additional information 78 in a simple format, adds them to the content, and distributes them.

  The downloaded PC additional information 77 is recorded in the portable device 5 as it is. On the other hand, after the PD additional information 78 is recorded in the portable device 5, it can be displayed on a display (not shown) based on an operation by the user.

  For example, when the content recorded in the portable device 5 is moved into the personal computer 1, the PC additional information 77 and the PD additional information 78 are transferred to the personal computer 1 together with the content. The transferred PD additional information 78 is recorded in the personal computer 1 as the PD additional information 72 as it is. On the other hand, after the PC additional information 77 is recorded as the PC additional information 70 in the personal computer 1, it can be displayed on the display 20 based on the operation by the user.

  As described above, the EMD server 3 adds the PC additional information that can be displayed on the personal computer 1 and the PD additional information that can be displayed on the portable device 5 to the content for distribution. As a result, the personal computer 1 and the portable device 5 can each display additional information described in a format that can be read by the personal computer 1 and the portable device 5, respectively.

  Next, a transfer process of content and additional information when moving content (including import) from the portable device 5 to the personal computer 1 will be described with reference to the flowchart of FIG.

  When the user selects a song name to be moved in from the field 102 of the window shown in FIG. 10 and presses the move-in button 104-1, the transfer processing unit 63 performs move-in pre-processing authentication in step S1. . The move-in pre-processing authentication performed here is, for example, whether the content corresponding to the selected song name is content that can be moved in, whether it is legitimate content that has not been tampered with, or communication This is processing such as whether or not the previous portable device 5 is a valid communication destination.

  If the authentication is successful, the transfer processing unit 63 converts and copies the music file 76 recorded in the portable device 5 to the personal computer 1 in step S2. More specifically, the transfer processing unit 63 uses the PD plug-in 75 to record the music file 76 recorded in the portable device 5 (for example, “in the directory having the name“ HIFI ”shown in FIG. 7” A song file named “A3D00001.MSA”) is read, the read song file 76 is converted and copied, and the song file storage unit 68 is sent via the song management unit 64, file search unit 66, and database 67. Are stored as a music file 69.

  In step S <b> 3, the transfer processing unit 63 acquires an additional information path from the music file 76 recorded in the portable device 5. Specifically, the transfer processing unit 63 adds the music file 76 recorded in the portable device 5 via the PD plug-in 75 (in this case, the music file named “A3D00001.MSA”). The additional information path included (the storage location of the additional information 77 for PC) is acquired.

  In step S4, the transfer processing unit 63 reads the PC additional information 77 from the additional information path acquired in step S3, and causes the personal computer 1 to copy it. Specifically, the transfer processing unit 63 has the additional information 77 for PC recorded in the portable device 5 via the PD plug-in 75 (in this case, “PACKAGES” shown in FIG. 7 as a name). The directory having the name “PKG00001” in the directory) is read, the read PC additional information 77 is copied, and the song file storage unit 68 is passed through the song management unit 64, the file search unit 66, and the database 67. Are stored as additional information 70 for PC.

  In step S <b> 5, the transfer processing unit 63 backs up the PD additional information 78 recorded in the portable device 5 to the personal computer 1. Specifically, the transfer processing unit 63 uses the PD plug-in 75 to add the PD additional information 78 (in this case, “A3D00001.A” in the directory for managing the music file 76 recorded in the portable device 5. The additional information for PD 78) included in the music file named “MSA” is read out, the read additional information for PD 78 is backed up, and the music management unit 64, file search unit 66, and database 67 are stored. Thus, the additional information 72 for PD is stored in the music file storage unit 68.

  In step S <b> 6, the transfer processing unit 63 sets (writes) an additional information path in the song file 69 on the personal computer 1. Specifically, the transfer processing unit 63 adds the PC addition stored in the song file storage unit 68 in step S4 to the song file 69 stored (copied) in the song file storage unit 68 in step S2. An additional information path indicating the storage location of the information 70 is set.

  In step S7, the transfer processing unit 63 determines whether or not the music file 69 and the additional information (PC additional information 70 and PD additional information 72) have been successfully written, that is, the music file 69 is correctly stored in the music file storage unit 68. If it is determined whether or not the writing of the music file 69 and the additional information has been successful, the process proceeds to step S8 to perform move-in post-processing authentication. The move-in post-processing authentication performed here is, for example, processing such as whether or not the content is correctly moved in the music file storage unit 68 of the database 67 and whether or not there is a missing file.

  In step S9, the transfer processing unit 63 uses the PD plug-in 75 to add the PC additional information 77 on the portable device 5 (in this case, “PKG00001” in the directory having the name “PACKAGES” shown in FIG. Delete the directory that has "

  In step S10, the transfer processing unit 63 assigns the name “A3D00001.MSA” in the directory having the name “HIFI” in the portable device 5 via the PD plug-in 75. Deleted song files).

  When the content move-in is completed normally by the above steps S1 to S10, the GUI unit 61 displays the song name corresponding to the moved-in content in the field 101 of the window shown in FIG. The song name is deleted from the field 102.

  For example, when the user selects a song title of the moved-in content and selects the “Property” item in the “File” item of the player unit 102, the GUI unit 61 displays additional information for PC in step S11. 70 is displayed on the display 20. As a result, a property screen as shown in FIG. 13 is displayed on the display 20.

  If it is determined in step S7 that the music file 69 and the additional information have not been successfully written, that is, the music file 69 and the additional information are not correctly stored in the music file storage unit 68, the process proceeds to step S12 and transferred. The processing unit 63 deletes the music file 69 copied to the music file storage unit 68 in the process of step S2, and in step S13, the PC additional information 70 copied to the music file storage unit 68 in the process of step S4. In step S14, the PD additional information 72 that has been backed up and copied to the music file storage unit 68 in step S5 is deleted, and the process ends.

  As described above, when the content recorded in the portable device 5 is moved into the personal computer 1, the music file and additional information of the content are first copied to the personal computer 1, and the music file and additional information are written (copied). When it is determined that the music file and the additional information on the portable device 5 are deleted, the content and the additional information can be transferred without losing data.

  Further, since the EMD server 3 distributes the PC additional information described in a highly extensible format and the PD additional information described in a simple format together with the content, the personal computer 1 uses the PC additional information. 70 can be displayed, and the portable device 5 can display the PD additional information 78.

  Next, a transfer process of content and additional information when moving content from the personal computer 1 to the portable device 5 will be described with reference to the flowchart of FIG.

  When the user selects a song name to be moved out from the field 101 of the window shown in FIG. 10 and presses the move-out button 104-2, the transfer processing unit 63, in step S31, performs the move-out pre-processing authentication. I do. The move-out pre-processing authentication performed here is, for example, whether the content corresponding to the selected song name is content that can be moved out, whether it is legitimate content that has not been tampered with, or This is processing such as whether or not the portable device 5 of the communication destination is a valid communication destination.

  If the authentication is successful, the transfer processing unit 63 converts and copies the music file 69 stored in the music file storage unit 68 of the database 67 to the portable device 5 in step S32. Specifically, the transfer processing unit 63 reads the song file 69 recorded in the song file storage unit 68 (for example, “track.omg” in the directory having the name “Song-A” shown in FIG. 6). The music file with the name is read out, the read music file 69 is converted and copied, and is recorded as the music file 76 on the portable device 5 via the PD plug-in 75.

  In step S33, the transfer processing unit 63 adds the content included in the song file 69 (in this case, the song file named “track.omg”) stored in the song file storage unit 68 of the database 67. An information path (storage location of the PC additional information 70) is acquired.

  In step S <b> 34, the transfer processing unit 63 reads the PC additional information 70 from the additional information path acquired in step S <b> 33 and copies it to the portable device 5. Specifically, the transfer processing unit 63 stores the PC additional information 70 (in this case, in the directory having the name “Song-A” shown in FIG. 6) stored in the song file storage unit 68. The directory having “PKG00001” in its name) is read, and the read PC additional information 70 is copied and recorded as PC additional information 77 on the portable device 5 via the PD plug-in 75.

  In step S35, the transfer processing unit 63 stores the additional information for PD 72 stored in the song file storage unit 68 (in this case, “Song-A” in the directory having the name “Song-A” shown in FIG. 6). The PD additional information 72) named “msainf.msf” is read, and the read PD additional information 72 is embedded in the music file 76 copied to the portable device 5 in the process of step S32. That is, for example, the PD additional information 78 is embedded in the music file named “A3D00001.MSA” in the directory having the name “HIFI” shown in FIG.

  In step S36, the transfer processing unit 63 stores the PC additional information 77 recorded in the portable device 5 in step S34 in the music file 76 recorded (copied) in the portable device 5 in step S32. An additional information path indicating is set.

  In step S37, the transfer processing unit 63 determines whether or not the music file 76 and additional information (PC additional information 77 and PD additional information 78) have been successfully written, and the music file 76 and additional information are written. When it determines with having succeeded, it progresses to step S38 and performs post-move-out process authentication. The post-move-out process authentication performed here is, for example, a process such as whether or not the content is correctly moved out on the portable device 5 or whether or not there is a missing file.

  In step S39, the transfer processing unit 63 adds the PC additional information 70 stored in the song file storage unit 68 of the database 67 (in this case, in the directory having the name “Song-A” shown in FIG. 6). Directory with the name "PKG00001").

  In step S40, the transfer processing unit 63 adds the PD additional information 72 stored in the song file storage unit 63 (in this case, “msainf.” In the directory having the name “Song-A” shown in FIG. 6). The PD additional information 72) named “msf” is deleted.

  When the content move-out is normally completed by the processes in steps S31 to S40, the GUI unit 61 displays the song name corresponding to the moved-out content in the field 102 of the window shown in FIG. At the same time, the song name is deleted from the field 101.

  If it is determined in step S37 that the music file 76 and the additional information have not been successfully written, the process advances to step S41, and the transfer processing unit 63 copies the music file 76 on the portable device 5 in the process of step S32. In step S42, the PC additional information 77 copied on the portable device 5 in the process of step S34 is deleted, and the process ends.

  As described above, when the content recorded in the personal computer 1 is moved out to an external device such as the portable device 5, the music file and the additional information of the content are first copied to the portable device 5, and the music file and the additional information are copied. When it is determined that writing (copying) has been successful, the music file and the additional information on the personal computer 1 are deleted, so that the content and the additional information can be transferred without losing data. .

  In the above, the PC additional information 70 is displayed on the display 20 on the personal computer 1. However, the present invention is not limited to this, and a backup copy of the PC additional information 70 is created and used for PC editing. The additional information 71 may be displayed on the display 20.

  Next, a transfer process of content and additional information when moving content from the portable device 5 to the personal computer 1 will be described with reference to the flowchart of FIG.

  Since the processes in steps S61 to S70 are the same as the processes in steps S1 to S10 in FIG. 18, their descriptions are omitted.

  In step S71, the transfer processing unit 63 reads the PC additional information 70 copied to the song file storage unit 68 of the database 67 in the process of step S64, and creates a PC editing additional information 71 by making a backup copy thereof. .

  When the content move-in is completed normally by the above steps S61 to S71, the GUI unit 61 displays the song name corresponding to the moved-in content in the field 101 of the window shown in FIG. The song name is deleted from the field 102.

  For example, when the user selects a song title of the moved-in content and selects “property” in the “file” item of the player unit 102, the GUI unit 61 adds the PC editing addition in step S72. Information 71 is displayed on the display 20. As a result, a property screen as shown in FIG. 13 is displayed on the display 20.

  Each of the processes in steps S73 to S75 is the same as each of the processes in steps S12 to S14 of FIG.

  Thus, by displaying the PC editing additional information 71 on the display 20, the original PC additional information 70 is not edited by the user. Therefore, even if the user edits the additional information according to his / her preference, at the time of the move-out, the PC editing additional information 71 is discarded and the original PC additional information 70 is transferred to customize the additional information. It is possible to prevent the additional information from being distributed.

  In addition, it is possible for a maker that provides content to prevent content with illegal additional information from being circulated, so that content can be distributed with peace of mind and the music distribution service market can be expanded.

  In the above, the transfer of the additional information when moving the content in or out is described. That is, the personal computer 1 stores the PC additional information 70, the PC editing additional information 71, and the PD additional information 72, and the PC additional information 70 or the PC editing additional information 71 is used to edit the additional information. Further, when the content is moved out to the portable device 5, the PC additional information 70 recorded in the personal computer 1 is transferred, and the PD additional information 72 is transferred to the portable device 5 as it is. It was to so.

  Further, the portable device 5 stores the additional information 77 for PC and the additional information 78 for PD, the additional information for PD 77 is used for editing the additional information, and the content is moved into the personal computer 1. The PD additional information 78 recorded (stored) in the portable device 5 is transferred, and the PC additional information 77 is transferred to the personal computer 1 as it is.

  Next, content and additional information transfer processing when content is checked out from the personal computer 1 to the portable device 5 will be described with reference to the flowchart of FIG.

  When the user selects a song name to be checked out from the field 101 of the window shown in FIG. 10 and presses the checkout button 103-2, the transfer processing unit 63 in step S91, the pre-checkout process authentication is performed. I do. Check-out pre-processing authentication performed here is, for example, whether the content corresponding to the selected song name is content that can be checked out, whether it is legitimate content that has not been tampered with, or This is processing such as whether or not the portable device 5 of the communication destination is a valid communication destination.

  If the authentication is successful, the transfer processing unit 63 converts and copies the music file 69 stored in the music file storage unit 68 of the database 67 to the portable device 5 in step S92. In step S <b> 93, the transfer processing unit 63 acquires an additional information path from the song file 69 stored in the song file storage unit 68 of the database 67.

  In step S 94, the transfer processing unit 63 reads the PC editing additional information 71 stored in the song file storage unit 68 of the database 67 and copies it to the portable device 5. Specifically, the transfer processing unit 63 stores the PC editing additional information 71 (in this case, in the directory having the name “Song-A” shown in FIG. 6) stored in the song file storage unit 68. Directory having “PKG00001-edit” in the name) is copied to the portable device 5 via the PD plug-in 75. As a result, the PC additional information 77 is recorded in the portable device 5.

  In step S95, the transfer processing unit 63 creates the PD additional information 72 based on the PC editing additional information 71 read out in step S94, and generates the PD additional information 72 in step S92. It is embedded in the music file 76 that was copied. In step S <b> 96, the transfer processing unit 63 sets an additional information path in the music file 76 on the portable device 5.

  In step S97, the transfer processing unit 63 determines whether or not the writing of the music file 76 and the additional information has been successful. If it is determined that the writing of the music file 76 and the additional information has been successful, the process proceeds to step S98. Perform post-processing authentication. The post-checkout authentication performed here is, for example, whether or not the content has been correctly checked out on the portable device 5, whether or not there is a missing file, or updating the number of remaining checkouts. It is processing.

  If it is determined in step S97 that writing of the music file 76 and the additional information is not successful, the process proceeds to step S99. Since each of the processes of step S99 and step S100 is the same as each of the processes of step S41 and step S42 of FIG. 19, the description thereof is omitted.

  As described above, when the content recorded in the personal computer 1 is checked out to an external device such as the portable device 5, a copy of the PC editing additional information 71 edited on the personal computer 1 is used as the PD additional information 72. Since it is transferred to the portable device 5 and embedded in the music file 76, the PC additional information 70 or PC editing additional information 71 displayed on the display 20 of the personal computer 1 and the portable device 5 are not shown. The PD additional information 78 displayed on the display can be matched, and the convenience for the user can be improved.

  In addition, the user can edit the PD additional information 78 displayed on the portable device 5, and the edited PD additional information 78 is discarded at the time of check-in. The edited PD additional information 78 may be overwritten on the PD additional information stored in the song file storage unit 68 of the personal computer 1.

  Incidentally, some external devices such as the portable device 5 do not have a display function such as the display 20 of the personal computer 1, and it is useless to transfer additional information of content to such an external device. In addition, it takes time to transfer the content.

  Therefore, when the user checks out the content to the portable device 5 that does not have the display function, the transfer of the additional information can be canceled. In this case, for example, the user selects the “setting” item in the “tool” item of the player unit 102 of the window shown in FIG. The setting screen is displayed on the display 20.

  As shown in FIG. 22, a plurality of tabs are arranged on the setting screen, and the GUI unit 61 displays a message when a tab named “external device / media” is activated. A check box for setting whether to display, whether to display a button, and whether to write additional information is displayed.

  The user can transfer additional information at the time of check-out by checking a check box 161 for setting whether or not to write additional information among the check boxes shown in FIG. By removing the check, it is possible to prevent additional information from being transferred at the time of checkout.

  Next, with reference to the flowchart of FIG. 23, the transfer process of content and additional information when the content is checked out from the personal computer 1 to the portable device 5 after setting whether or not to transfer the additional information will be described. .

  Since each of the processing of step S121 and step S122 is the same as each of the processing of step S91 and step S92 of FIG. 21, description thereof will be omitted.

  In step S123, the transfer processing unit 63 determines whether to transfer additional information, that is, as described above, whether the check box 161 on the setting screen illustrated in FIG. 22 is checked by the user. If it is determined that additional information is to be transferred, the process proceeds to step S124.

  Since each of the processes from step S124 to step S127 is the same as each of the processes from step S92 to step S96 in FIG. 21, the description thereof is omitted.

  If it is determined in step S123 that the additional information is not transferred, that is, the user deselects the check box 161 on the setting screen shown in FIG. 22, the process proceeds to step S128.

  Since each of the processing from step S128 to step S131 is the same as each of the processing from step S97 to step S100 in FIG. 21, the description thereof is omitted.

  If it is determined in step S123 that additional information is not transferred, the process in step S125 is skipped (that is, the PC additional information 77 has not been copied). The process is terminated without performing it.

  As described above, when the content is checked out to an external device having no display function, the check-out time can be shortened by setting so that the additional information of the content is not transferred.

  Next, referring to the flowchart of FIG. 24, when the additional information edited by the user is deleted, the additional information for PC is overwritten on the additional information for PC editing to restore the original additional information. Processing will be described.

  If the user deletes the edited additional information by mistake, for example, when the user presses the return button 151 on the property screen shown in FIG. The additional information path is acquired from the song file 69 stored in the file storage unit 68. Specifically, the song management unit 64 uses the file search unit 66 and the database 67 to store the song recorded in the song file storage unit 68 as a file 69 (for example, “Song-A” shown in FIG. 6). The additional information path (storage location of the additional information for PC 70) included in the music file named “track.omg” in the directory having the name is acquired.

  In step S152, the song management unit 64 uses the additional information path acquired in the process of step S151 to name the additional information for PC 70 (in this case, “PKG00001” in the directory whose name is “Song-A”). Directory). In step S153, the song management unit 64 stores the old PC editing additional information 71 (in this case, “PKG00001 in the directory having the name“ Song-A ”) stored in the song file storage unit 68 of the database 67. directory with the name "-edit".

  In step S154, the song management unit 64 deletes the old PC editing additional information 71 acquired in the process of step S153. In step S155, the song management unit 64 creates additional PC editing additional information 71 by copying the additional PC information 70 acquired in the process of step S152.

  In step S155, the song management unit 64 registers (stores) the PC editing additional information 71 created in the process of step S154 in the song file storage unit 68, and updates the additional information path of the PC editing additional information 71. .

  As described above, even when the user accidentally deletes the edited additional information, the original additional information can be easily restored by operating the return button 151 shown in FIG. As a result, the user does not have to fear to edit the additional information intentionally or accidentally, and can operate the jukebox application program with peace of mind.

  In the above-described example, when content is distributed from the EMD server 3, the PC additional information and the PD additional information are added to the content for distribution, but the present invention is not limited to this.

  That is, for example, the user downloads content and additional information distributed from the EMD server 3 to the portable device 5, connects the portable device 5 on which the content and additional information have been downloaded to a personal computer, and imports (moves in) the portable device 5. In such a case, if additional information is downloaded together with the content, the portable device 5 having a smaller storage capacity than the storage capacity of the HDD 21 of the personal computer 1 reduces the number of contents that can be written.

  Therefore, the EMD server 3 does not distribute the additional information of the content, but distributes the URL for accessing the EMD server 3 providing the additional information or a website established by the other server together with the content. The amount of data stored in the portable device 5 can be saved.

  Next, processing for downloading content distributed from the EMD server 3 to the portable device 5 and importing (moving in) it from the portable device 5 to the personal computer 1 will be described with reference to the flowchart of FIG.

  The portable device 5 downloads and records the content distributed from the EMD server 3. At this time, the portable device 5 records PC additional information 77 including a URL for accessing a website providing the additional information together with the content.

  When the user performs an operation of moving the content downloaded to the portable device 5 into the personal computer 1, the transfer processing unit 63 copies the PC additional information 77 recorded on the portable device 5 in step S171. Then, it is stored as it is as additional PC information 70 in the music file storage section 68 of the database 67 of the personal computer 1.

  In step S172, the transfer processing unit 63 names the PC additional information 70 (for example, “PKG00001” in the directory having the name “Song-A” in FIG. 6) stored in the song file storage unit 68 of the database 67. Read the data named “package.xml”. In step S173, the transfer processing unit 63 reads items included in “package.xml” read in the process of step S172.

  In step S174, the transfer processing unit 63 determines whether the item read in the process of step S173 is a URL, and determines that the read item is not a URL, that is, an image or a lyrics file. In step S175, the image or lyrics file is read.

  If it is determined in step S174 that the read item is a URL, the process proceeds to step S176, where the transfer processing unit 63 activates a web browser, connects to the EMD server 3 or the like via the network 2, and the URL The web page specified by is displayed on the display 20. The user performs a predetermined operation on the web page displayed on the display 20 to download an image or a lyrics file.

  In step S177, the transfer processing unit 63 determines whether all items have been read. If it is determined that reading has not been completed, the transfer processing unit 63 returns to step S173 and repeats the above-described processing. If it is determined in step S177 that all items have been read, the process ends.

  Therefore, the EMD server 3 does not distribute the additional information of the content, but the location of the additional information such as a URL for accessing the EMD server 3 that provides the additional information or a website established by the other server. By distributing the information to be shown together with the content, the amount of data stored in the portable device 5 can be saved.

  Furthermore, when additional information is downloaded using the personal computer 1, the call charge is constant no matter how many hours a connection is made to a predetermined telephone number between a predetermined time and a predetermined time (for example, 11:00 pm to 8:00 am). Within the service time, the personal computer 1 can be used to access the EMD server 3 and acquire additional information. Thereby, the user can download the additional information of a plurality of contents collectively without worrying about the connection time.

  Although the content has been described as music data, it may be a moving image, a still image, numerical data, or a program.
