As shown in FIG. 9, in the field 161, “normal transfer” for setting the normal transfer mode in which the converted content 51 that is the final checkout target is transmitted as it is, and the converted content 51 at a low bit rate. “Low bit rate fixed transfer” for setting the mode of low bit rate fixed transfer to be converted and transmitted is displayed. Check boxes are displayed for "Normal transfer" and "Low bit rate fixed transfer", and the user can check the check box to select the normal transfer mode or low bit rate fixed transfer. One of the modes can be selected. In FIG. 9, the user has selected the normal transfer mode.

  Next, recording processing for recording the content 50 performed by the personal computer 1 in the content storage unit 47 will be described with reference to FIG. In this recording process, for example, the combo box 61 (FIG. 3), the “Get Music” button 62, and the “My Library” button 63 are operated by the user, and the operation window 60 of FIG. When will be started.

  In step S11, the operation control application 41 determines whether or not the content 50 to be recorded has been selected by the user. Specifically, the user operates the input unit 18 while viewing the information corresponding to the content 50 displayed in the field 71 of the operation window 60 in FIG. 3, and moves the cursor to the information corresponding to the desired content 50. The selected button 70 is operated (selected). The input unit 18 supplies the operation control application 41 with an input signal representing the content 50 corresponding to the information selected by the user. The operation control application 41 determines whether or not the content 50 to be recorded is selected by determining whether or not an input signal representing the content 50 selected by the user is supplied from the input unit 18.

  In step S11, when it is determined that the content 50 to be recorded is not selected by the user, the operation control application 41 waits until the content 50 is selected.

  On the other hand, if it is determined in step S11 that the content 50 to be recorded has been selected by the user, the process proceeds to step S12, and the operation control application 41 determines whether or not the recording button 81 (FIG. 3) has been operated by the user. If the recording button 81 is not operated, the process waits until the recording button 81 is operated.

  On the other hand, when it is determined in step S12 that the recording button 81 has been operated by the user, the process proceeds to step S13, and the operation control application 41 displays the field 91 (FIG. 4) on the display unit 17.

  In step S14, the operation control application 41 determines whether or not M pieces of setting information have been set by the user.

  Specifically, the user operates the input unit 18 and moves the cursor to select a desired combination of format and compression method from among the combinations of format and compression method displayed in the field 101 of FIG. Select. Thereafter, the user operates the combo box 102. At this time, the operation window 60 of FIG. 4 is updated to the operation window 60 of FIG. The user operates the input unit 18 and moves the cursor to select a desired bit rate from the bit rates displayed in the combo box 102. Then, the user operates the input unit 18 and operates the setting button 92 to set the combination of the selected format and compression method and the bit rate as setting information. The user repeats the same operation M times to set M pieces of setting information.

  Thereafter, the user operates the input unit 18 and operates the OK button 93 to finish setting the set M pieces of setting information. At this time, the input unit 18 supplies an input signal representing M pieces of setting information to the operation control application 41. The operation control application 41 determines whether or not M pieces of setting information have been set by determining whether or not an input signal representing M pieces of setting information has been supplied from the input unit 18.

  If it is determined in step S14 that the M pieces of setting information are not set by the user, the process proceeds to step S15, where the operation control application 41 determines whether or not a predetermined time has elapsed, If it is determined that has not elapsed, the process returns to step S14 to repeat the above-described processing.

  When it is determined in step S15 that the predetermined time has elapsed, the process proceeds to step S16, and the operation control application 41 formats the reproducible data format of the PD 32 connected to the communication unit 19 from the PD information storage unit 42. Data information such as compression method or bit rate is read out.

  In step S <b> 17, the operation control application 41 sets M pieces of setting information based on the data information of the PD 32. For example, based on the data information, the operation control application 41 selects M pieces of formats, compression methods, and bit rates that can be reproduced by the PD 32 in order from the highest quality, and sets (decides) M pieces of setting information. )

  As described above, the operation control application 41 determines that the setting information is not set by the user (when it is determined that M pieces of setting information are not set in step S14 and that a predetermined time has passed in step S15). In this case, since the setting information is set based on the data information of the PD 32, it is possible to prevent the content 50 from being converted in a format, compression method, or bit rate that cannot be reproduced by the PD 32. Thus, when the converted content 51 is checked out to the PD 32, the converted content 51 need not be converted again into a format, compression method, or bit rate that can be reproduced by the PD 32, and can be checked out. As a result, the content 50 can be checked out quickly.

  If it is determined in step S14 that M pieces of setting information have been set by the user, or after the processing in step S17, the operation control application 41 is selected by the data read management module 43 in step S11 in step S18. The acquisition destination of the content 50 is set.

  For example, if the information of the content 50 is selected from the field 71 of the operation window 60 shown in FIG. 3 in step S11, “Record CD” is selected in the combo box 61. Is acquired from the CD, and the CD that is the removable recording medium 21 mounted on the personal computer 1 is set as the acquisition destination of the content 50.

  Further, the operation control application 41 sets the content ID of the content 50 corresponding to the information represented by the input signal supplied from the input unit 18 in step S11 as the content ID of the content 50 to be recorded in the data read management module 43. To do.

  In step S19, the data read management module 43 generates one data read module 44, and sets the acquisition destination of the content 50 and the content ID of the content 50 set in step S18.

  In step S20, the operation control application 41 adds a setting ID to each of the M pieces of setting information set in step S14 or step S17, and sets the setting information in the data conversion management module 45.

  In step S21, the data conversion management module 45 generates M data conversion modules 46-1 to 46-M, and sets the setting information to which the M setting IDs set in step S20 are added. Specifically, the data conversion management module 45 sets different setting information for each of the M data conversion modules 46-1 to 46-M.

  In step S22, the data reading module 44 reads the content 50 to be recorded to which the set content ID is added from the acquisition destination set in step S21, and each of the data conversion modules 46-1 to 46-M. To supply. In step S22, the contents 50 to be recorded may not be read all at once, but may be read part by part. In this case, in step S23 described later, the data conversion modules 46-1 to 46-M convert the content 50 part by part.

  In step S23, the data conversion modules 46-1 to 46-M set the M settings set in step S20 to the format, compression method, or bit rate of the content 50 supplied from the data reading module 44 in step S22. Convert based on information. That is, the data conversion modules 46-1 to 46-M convert the content 50 at the same timing. The data conversion modules 46-1 to 46-M store the converted contents 51-1 to 51-M in the content storage unit 47 with the setting ID added to the setting information, respectively.

  Thus, in the process of step S23, the M data conversion modules 46-1 to 46-M convert one content 50, and M converted contents 51-1 to 51-M having different setting information are converted. Therefore, the reading module 44 only needs to read the content 50 once, and the recording processing overhead is reduced and the processing time of the recording processing is shortened as compared with the case where there is only one data conversion module. Can do. On the other hand, when there is one data conversion module, the data read module 44 reads the content 50 in order to generate M converted contents 51-1 to 51-M having different setting information. It is necessary to perform the process of converting the content 50 based on one setting information M times, and the overhead of the recording process increases.

  In addition, since the data reading module 44 can generate the M converted contents 51-1 to 51-M having different setting information by reading the content 50 only once, the data reading module 44 can perform the removable recording. When reading the content 50 from the medium 21 via the drive 20, the drive 20 needs to read M times when the same time for recording processing is set as when the content needs to be read M times. Compared to the case, it is possible to make the reading speed slower.

  In step S24, the data conversion modules 46-1 to 46-M display the content ID added to the recording target content 50, the setting ID added to the converted content 51 in step S23, and the M set in step S20. Each piece of setting information is stored in the content table 52 (FIG. 6) stored in the content storage unit 47.

  In step S25, the data read management module 43 discards the data read module 44. In step S26, the data conversion management module 45 discards the data conversion module 46 and ends the process.

  As described above, in the personal computer 1, the user can generate M different converted contents 51 by operating the recording button 81 once.

  Also, the data conversion module 46 can be generated and discarded, that is, the converted contents 51 with different setting information can be generated only by performing the processing of steps S21 and S26 once. Compared with the case where there is one, the recording processing time can be shortened. On the other hand, when there is one data conversion module, only one setting information can be set in the data conversion module. Therefore, M setting information is set in the data conversion module and the content 50 In order to perform conversion, it is necessary to generate and discard a data conversion module for setting different setting information M times. Accordingly, the recording processing time becomes long.

  Next, with reference to FIG. 11, a check-out process performed by the personal computer 1 for checking out the converted content 51 to the PD 32 will be described. In the checkout process, for example, the user operates the “My Library” button 63 (FIG. 7), the combo box 64, and the “transfer music” button 65, and the operation window 60 of FIG. Started when displayed.

  In step S41, the operation control application 41 determines whether or not the converted content 51 to be checked out is selected by the user. Specifically, the user operates the input unit 18 while viewing the information corresponding to the converted content 51 displayed in the field 111 of FIG. 7 and moves the cursor to the information corresponding to the desired converted content 51. Move. In the example of FIG. 7, three songs are displayed as a result of the process of FIG. 10 being performed three times. The input unit 18 supplies an input signal representing the content ID corresponding to the song name or artist name selected by the user to the operation control application 41. The operation control application 41 determines whether or not the converted content 51 to be checked out is selected by determining whether or not an input signal representing a content ID corresponding to the song name or artist name selected by the user is supplied from the input unit 18. Determine whether it was done.

  If it is determined in step S41 that the converted content 51 to be checked out is not selected by the user, the operation control application 41 waits until the converted content 51 is selected.

  On the other hand, if it is determined in step S41 that the converted content 51 to be checked out is selected by the user, the process proceeds to step S42, and the operation control application 41 operates the checkout button 121 (FIG. 7) by the user. If the checkout button 121 is not operated, the process waits until the checkout button 121 is operated.

  On the other hand, if it is determined in step S42 that the checkout button 121 has been operated by the user, the process proceeds to step S43, and the operation control application 41 converts the data information of the checkout destination PD32 selected in the combo box 64 into PD information. Read from the storage unit 42.

  In step S44, the operation control application 41 converts the check-out target selected in step S41 from the content table 52 of the content storage unit 47 in which the content ID, setting ID, and setting information are stored in step S24 of FIG. The setting information corresponding to the content ID of the subsequent content 51 is read out.

  In step S45, the operation control application 41 displays the field 141 (FIG. 8) on the display unit 17, and the setting information of the converted content 51 to be checked out read in step S44 is displayed in the field 151 of the field 141. Among them, the format and the compression method included in the data information of the PD 32 read in step S43 are displayed. Further, the operation control application 41 causes the combo box 152 to display the bit rate included in the data information read in step S43 among the setting information read in step S44. That is, the operation control application 41 displays only the format, compression method, or bit rate of the data that can be played back by the checkout destination PD 32 among the setting information format, compression method, or bit rate of the converted content 51. .

  In step S46, the operation control application 41 determines whether or not the setting information displayed in the field 141 is selected by the user. If it is determined that the setting information is not selected by the user, the setting information is selected. stand by.

  On the other hand, if it is determined in step S46 that the setting information has been selected by the user, the process proceeds to step S47, and the checkout management module 48 uses the setting information selected by the user in the converted content 51 to be checked out. Corresponding post-conversion content 51 is selected as the final checkout target. Then, the checkout management module 48 generates one checkout module 49 (here, since the checkout destination PD6 is one of PD # 1, one checkout module 49 is generated) In the checkout module 49, a content ID and a setting ID corresponding to the setting information set by the user are set.

  In step S48, the checkout module 49 reads out the converted content 51 to be checked out last from the content storage unit 47 based on the content ID and the setting ID set in step S47, and the checkout destination selected by the user Check out at PD32.

  In step S49, the checkout management module 48 discards the checkout module 49 and ends the process.

  FIG. 12 is a diagram illustrating another functional configuration example of the personal computer 1. The same components as those in FIG. 2 are denoted by the same reference numerals as those in FIG.

  In FIG. 12, the data read management module 43 generates N data read modules 201-1 to 201-N instead of the data read module 44. Different acquisition destinations of the contents 200-1 to 200-N are set in the data reading modules 201-1 to 201-N, respectively. Therefore, the data reading modules 201-1 to 201-N can read the contents 200-1 to 200-N from, for example, each of N acquisition sources.

  Hereinafter, when it is not necessary to distinguish the contents 200-1 to 200-N, they are collectively referred to as the contents 200.

The content storage unit 47 in FIG. 12 stores N content groups 202-1 to 201-N. The content groups 202-1 to 201-N are groups of converted content obtained by converting the same content 200 based on different M pieces of setting information. For example, content group 202-1 is composed of converted the M converted content 203-1 ₁ to 203-1 _M based the same content 200 to M different configuration information. The other content groups 202-2 to 202-N are configured similarly to the content group 202-1. Accordingly, the content storage unit 47 stores N × M pieces of converted content 203-1 _{1 to} 203-M _N obtained by converting each of the N pieces of content 200-1 to 200-N based on M pieces of setting information. Is memorized.

Hereinafter, when it is not necessary to distinguish the data read management modules 201-1 to 201-N, they are collectively referred to as the data read management module 201. Further, when it is not necessary to distinguish the converted contents 203-1 _{1 to} 203- _MN , they are collectively referred to as the converted contents 203, and when it is not necessary to distinguish the content groups 202-1 to 202-N, These are collectively referred to as a content group 202.

  FIG. 13 is a flowchart of a recording process for recording the content 200 performed by the personal computer 1 of FIG. 10, for example, the user operates the combo box 61 (FIG. 3), the “capture music” button 62, and the “my library” button 63, and the operation of FIG. 3 is performed on the display unit 17. Starts when window 60 is displayed.

  In step S61, the input unit 18 accepts selection of the content 200 to be recorded by the user. Specifically, the user operates the input unit 18 while viewing the information corresponding to the content 200 displayed in the field 71 of the operation window 60 in FIG. 3, and moves the cursor to the information corresponding to the desired content 200. Let At this time, information corresponding to the plurality of contents 200-1 to 200-N is displayed in the operation window 60 of FIG.

  In step S62, the input unit 18 determines whether or not the selection button 70 (FIG. 3) has been operated by the user, and when it is determined that the selection button 70 has not been operated by the user, that is, the content received in step S61. If 200 is not determined as the recording target, the process returns to step S61 to accept selection of the content 200 to be recorded.

  On the other hand, if it is determined in step S62 that the selection button 70 has not been operated by the user, that is, if the content 200 accepted in step S61 is determined as a recording target, an input signal representing the determined content 200 Is supplied to the operation control application 41.

  In step S63, the operation control application 41 determines whether the user has operated the recording button 81 (FIG. 3). Specifically, the user operates the input unit 18 and operates the recording button 81. At this time, the input unit 18 supplies an input signal indicating that the recording button 81 has been operated to the operation control application 41. The operation control application 41 determines whether or not the recording button 81 has been operated by the user by determining whether or not an input signal indicating that the recording button 81 has been operated is supplied from the input unit 18.

  If it is determined in step S63 that the recording button 81 has not been operated, the process returns to step S61 and the above-described processing is repeated. Note that the content 200 that is determined as a recording target by the user may be the content 200 of a different acquisition destination or the content 200 of the same acquisition destination. When selecting the content 200 of a different acquisition destination as a recording target, the user operates the input unit 18 and operates the combo box 61 to select the acquisition destination. In the following, for convenience of explanation, it is assumed that N pieces of content 200-1 to 200-N are contents 200 stored in different acquisition destinations.

  In step S61, the content 200 stored in a plurality of acquisition destinations can be selected as a recording target, so that the user can select only the content 200 stored in one acquisition destination. Can be easily operated. On the other hand, when only the content 200 stored in one acquisition destination can be selected, the user selects one acquisition when selecting the content 200 stored in a plurality of acquisition destinations as a recording target. The destination is designated and the recording of the content 200 is instructed, and the process waits until the recording of the content 200 of the acquisition destination is completed. Then, the user designates a new acquisition destination and instructs the recording of the content 200, waits until the recording of the content 200 of the specified acquisition destination is completed, and then repeats the same processing. Therefore, the user has to judge whether or not the recording of the previously selected acquisition destination content 200 has been completed, and must instruct the recording of the acquisition destination content 200 to be selected next, which is troublesome.

  On the other hand, if it is determined in step S63 that the recording button 81 has been operated by the user, the process proceeds to step S64. Here, a state after it is determined in step S63 that the recording button 81 has been operated by the user will be described. By repeating the process of step S61 N times, N (N is a positive number) pieces of content 200-1 to 200-N are determined as recording targets. Note that the processing from step S64 to step S68 is the same as the processing from step S13 to step S17 in FIG.

  In step S69, the operation control application 41 sets the acquisition destination of the N pieces of content 200-1 to 200-N determined as recording targets in step S61 in the data read management module 43. Here, for example, the operation control application 41 sets the acquisition destination of the content 200 in the order in which the selection of the content 200 is accepted in step S61. Further, the operation control application 41 sets the content ID of the content 200 corresponding to the information represented by the input signal supplied from the input unit 18 in step S61, that is, the content ID of the content 200 to be recorded, in the data read management module 43.

  In step S70, the data read management module 43 generates N data read modules 201-1 to 201-N, and sets the acquisition destination of the N pieces of content 200 and the content ID of the content 200 set in step S69. To do. That is, different data 200 acquisition destinations are set in the N data reading modules 201-1 to 201-N.

  Here, for example, the data read management module 43 obtains the N contents 200-1 to 200-N in the order set in step S69, that is, in the order in which the selection is accepted by the input unit 18 in step S61. And the data reading module 201 are numbered in the order in which the acquisition destinations are set. For example, in the first step S 61, the number 1 is assigned to the data read module 201 in which the selection is accepted by the input unit 18 and the determined acquisition destination of the content 200 is set. In the following, the data reading module 201 with the number i is referred to as a data reading module #i.

  In step S <b> 71, the operation control application 41 adds a setting ID to each of the M pieces of setting information set in step S <b> 65 or step S <b> 68 and sets it in the data conversion management module 45.

  In step S72, the data conversion management module 45 generates M data conversion modules 46-1 to 46-M, and sets the setting information to which the M setting IDs set in step S71 are added. In step S73, the data read management module 43 sets a count value K of a counter (not shown) to 1.

  In step S74, the data reading module 201 to which the count value K is assigned, that is, the data reading module #K, is the content to be recorded with the set content ID added from the acquisition source set in step S70. 200 is read and supplied to each of the data conversion modules 46-1 to 46-M.

  In step S75, the data conversion modules 46-1 to 46-M set the M settings set in step S71 for the format, compression method, or bit rate of the content 200 supplied from the data reading module 44 in step S74. Convert based on information. The data conversion modules 46-1 to 46-M store the converted M pieces of converted content 203 in the content storage unit 47 with the setting IDs added to the setting information, respectively. Here, the M converted content 203 after conversion is a component of the same content group 202.

  In step S76, the data conversion modules 46-1 to 46-M set the content ID added to the content 200 to be recorded, the setting ID added to the converted content 203 after conversion in step S75, and the setting in step S70. The set M pieces of setting information are stored in the content table 52 (FIG. 6) stored in the content storage unit 47, and the process proceeds to step S77.

  In step S77, the data read management module 43 increments the count value K by 1. In step S78, the data read management module 43 determines whether the count value K is greater than the value N, and determines that the count value K is not greater than the value N (that is, the count value K is less than or equal to the value N). If this is the case, that is, if all of the content 200 to be recorded has not been converted, the process returns to step S74 and the above-described processing is repeated. This process is repeated until the count value K becomes larger than the value N, that is, until N times of reading is performed and the read content 200 is converted and stored.

  On the other hand, if it is determined in step S78 that the count value K is greater than the value N, that is, all of the N pieces of content 200-1 to 200-N determined as recording targets in step S62 are converted and stored. In the case where the data read management module 43 has received the data, the data read management module 43 discards the N data read modules 201 in step S79. In step S80, the data conversion management module 45 discards the M data conversion modules 46 and ends the process.

  In the above description, the acquisition destinations of the N contents 200-1 to 200-N determined as the recording targets in step S62 are all different, but the N contents 200 selected as the recording targets are different. If there is the same acquisition destination, the data reading module 44 can be generated for each acquisition destination of the content 200 without generating N data reading modules 44.

  The setting information can be information specifying the number of channels, for example, in addition to information specifying the format, compression method, or bit rate.

  Furthermore, in the above description, OpenMG and WAV are adopted as the format of the setting information. However, the format is not limited to this, but MP3 (MPEG (Moving Picture Experts Group) -1 Audio Layer 3) or WMA (Windows (registered trademark)) ) Media Audio) format can also be used. In addition, ATRAC3, ATRAC3plus, and PCM are adopted as the compression method of the setting information, but the compression method such as MP3, TwinQV (trademark), or AAC (MPEG2 Advance Audio Coding) can also be adopted. . Furthermore, the bit rate of the setting information can be an arbitrary value.

  Here, in this specification, the processing steps for describing a program for causing a computer to perform various types of processing do not necessarily have to be processed in time series according to the order described in the flowchart, but in parallel or individually. This includes processing to be executed (for example, parallel processing or processing by an object).

  Further, the program may be processed by a single computer, or may be processed in a distributed manner by a plurality of computers. Furthermore, the program may be transferred to a remote computer and executed.
