Thus, it is possible to select music data of a desired music from a large number of downloadable music data by sequentially narrowing down by type.

  In addition to this configuration, in the case of this data storage / reproduction device 21, the central processing unit 53 constructs a music information database on the hard disk of the hard disk drive 55. When the central processing unit 53 reads the music data from the CD and stores it in the hard disk, the disk information corresponding to the music data (that is, the disk information acquired from the disk information providing server SV2) is stored in the music information database in the hard disk. sign up. When the central processing unit 53 downloads music data from the music data distribution server SV1 and stores it in the hard disk, the central processing unit 53 registers the attribute information acquired from the music data distribution server SV1 together with the music data in the music information database in the hard disk. .

  The central processing unit 53 registers the disc information and attribute information in the music information database in the hard disk and updates the music information database (that is, every time music data is stored in the hard disk). On the basis of the attribute information, the number of stored genres or artists (that is, the genre name or artist name) for the music data stored in the hard disk is calculated (hereinafter referred to as the number of music data). At this time, the central processing unit 53 registers the calculation result for each genre or artist in the music information database in the hard disk as statistical data for the music data stored in the hard disk, and updates the contents of the statistical data. Further, when the statistical data is generated, the central processing unit 53 determines the number of music data exceeding a predetermined number selected in advance based on the statistical data, and the genre corresponding to the number of music data exceeding the predetermined number. Detect name or artist name. The central processing unit 53 registers the detected genre name or artist name as a keyword in the music information database in the hard disk and updates the content of the keyword. In this way, the central processing unit 53 appropriately updates the keyword as information indicating the user's preference with respect to the music data stored in the hard disk (that is, the music acquired by the user using the data storage / playback device 21). Hold while.

  In this state, the central processing unit 53 receives an operation input signal for requesting the user to acquire the music selection page information 32 via the operation input unit 50, and in response to this, the central processing unit 53 sends the page information request signal to the music data distribution server. When it is transmitted to SV1, it is detected whether or not the uppermost music selection page information 32 transmitted from the music data distribution server SV1 is taken in. When the central processing unit 53 detects that the highest-order music selection page information 32 has been taken in, the central processing unit 53 generates a music selection image 70 and displays it on the display 58 as described above. The genre list information 33 is determined according to the list identifier. Further, the central processing unit 53 compares the type in the type list 37 included in the genre list information 33 determined in the music selection page information 32 with the keyword registered in the music information database in the hard disk. Thus, the central processing unit 53 determines whether or not the genre list information 33 includes a type that at least partially matches the keyword. As a result, if the category that matches the keyword is included in the genre list information 33, the central processing unit 53 collects the sample music identification information corresponding to the type that matches the keyword from the genre list information 33. At the same time, the purchase page address corresponding to the type (that is, corresponding to the collected sample music identification information) is collected. Then, as shown in FIG. 15, the central processing unit 53 creates a list 108 of trial song identification information collected from the genre list information 33 (hereinafter referred to as a collection identification information list) 108 and A list 109 of collected purchase page addresses (hereinafter referred to as a collection address list) 109 is created. Further, the central processing unit 53 associates the collection identification information list 108 and the collection address list 109 (that is, associates the corresponding trial song identification information and the purchase page address with each other) list information (hereinafter referred to as continuous trial list information). 110), and the generated continuous audition list information 110 is temporarily stored in the RAM 56 or the hard disk of the hard disk drive 55.

  Further, when the collection of the trial song identification information and the corresponding purchase page address from the genre list information 33 is finished, the central processing unit 53 automatically (that is, by user operation) according to the selected page address in the genre list information 33. A page information request signal is transmitted to the music data distribution server SV1 (regardless of whether there is an acquisition request for the lower music selection page information 32A and 32B). As a result, the central processing unit 53 transmits the music selection page information 32A and 32B of the lower music selection page information 32A and 32B (that is, the music selection page information 32A and 32B that can be directly shifted from the highest music selection page information 32) transmitted from the music data distribution server SV1. ) Is detected.

  When the central processing unit 53 detects that the music selection page information 32A and 32B that is one level lower than the highest level is taken in, the central processing unit 53 performs artist list information 39A and 39B according to the list identifier in the music selection page information 32A and 32B. Is determined. Further, the central processing unit 53 compares the type in the type list 43 included in the artist list information 39A and 39B determined in the music selection page information 32A and 32B with the keyword registered in the music information database in the hard disk. As described above, the sample music identification information related to the keyword and the corresponding purchase page address are collected from the artist list information 39A and 39B as described above. Then, the central processing unit 53 updates the continuous listening list information 110 by adding the sample music identification information and the purchase page address collected from the artist list information 39A and 39B to the continuous listening list information 110 in association with each other. To do.

  Further, when the collection of the trial song identification information and the corresponding purchase page address from the artist list information 39A and 39B is completed, the central processing unit 53 automatically (that is, according to the selected page address in the artist list information 39A and 39B) (that is, The page information request signal is transmitted to the music data distribution server SV1 (regardless of whether there is an acquisition request for the lower-order music selection page information 32AA to 32BA by the user operation). As a result, the central processing unit 53 allows the music selection page information 32AA to 32BA transmitted from the music data distribution server SV1 (that is, the music selection page that can be transited directly from the music selection page information 32A and 32B one level lower than the highest level). It is detected whether the information 32AA to 32BA) is taken in. When the central processing unit 53 detects that the music selection page information 32AA to 32BA is taken in, the central processing unit 53 determines the music list information 45A to 45C according to the list identifier in the music selection page information 32AA to 32BA. In this case, the central processing unit 53 collects all the sample music identification information included in the music list information 45A to 45C determined in the music selection page information 32AA to 32BA without using a keyword, and the collection The purchase page address corresponding to the audition music identification information is also collected. Then, the central processing unit 53 adds the sample song identification information collected from the song list information 45A to 45C and the corresponding purchase page address to the continuous sample list information 110 in association with each other, thereby adding the continuous sample list information 110. To update.

  In this way, when the user requests acquisition of the highest-order music selection page information 32, the central processing unit 53 responds to this request by requesting the highest-order music selection page information for at least two layers and, for example, 1 more than this. While automatically acquiring the music selection page information 32A and 32B in the lower hierarchy in sequence, the sample music identification information related to the keyword and the corresponding purchase page address are collected from the music selection page information 32 and 32A and 32B. In addition, the central processing unit 53 continues to automatically acquire the music selection page information 32AA to 32BA of the lower ranks for at least two layers, and from the acquired music selection page information 32AA to 32BA, all the sample music identification information and the corresponding Collect purchase page addresses. Then, the central processing unit 53 generates the continuous audition list information 110 (FIG. 15) using the audition music identification information collected from the music selection page information 32, 32A to 32BA and the corresponding purchase page address.

  Incidentally, each time the central processing unit 53 takes in the highest-order music selection page information 32 from the music data distribution server SV1 and starts collecting the trial music identification information, the music selection page information used to collect the trial music identification information. A collected and used page list for discriminating between 32 and 32A to 32BA is created and temporarily stored in the RAM 56 or the hard disk of the hard disk drive 55. Then, each time the central processing unit 53 uses each piece of music selection page information 32, 32A to 32BA for collecting the sample music identification information, the central processing unit 53 stores the pieces of music selection page information 32, 32A to 32BA used to collect the sample music identification information. Add page identification information to the collected used page list. Therefore, the central processing unit 53 determines whether or not each piece of music selection page information 32, 32A to 32BA has been used for collecting the trial song identification information based on the contents of the collected used page list. Can do. As a result, the central processing unit 53 redundantly uses the same music selection page information 32, 32A to 32BA for collecting the sample music identification information, and wastefully executes the process for collecting the sample music identification information. It is avoiding that.

  By the way, the central processing unit 53 collects the first sample music identification information from all the music selection page information 32, 32A to 32BA according to preset setting information, or a predetermined number of sample music identification information. When the collection of the sample music identification information from all the music selection page information 32, 32A to 32BA is completed, the sample music is continuously automatically output according to the continuous sample list information 110 to the user. Let them audition. That is, when the central processing unit 53 starts continuous automatic output of the sample music, the central processing unit 53 obtains one (first) sample music identification information in the continuous sample list information 110 according to, for example, the list of the sample music identification information. It is automatically selected as identification information of attention sample music to be noticed for specifying the sample music. Then, the central processing unit 53 requests corresponding sample data from the music data distribution server SV1 in accordance with the sample music identification information selected as the target sample music identification information. As a result, when the trial data is transmitted from the music data distribution server SV1 in the streaming format, the central processing unit 53 receives the trial data through the network interface 62 and the communication processing unit 61 in order and converts the trial data into the trial data. On the other hand, after the reproduction processing is performed by the data processing unit 60, the audio processing unit 63 performs the audio processing, and sends the obtained audition signal to the speaker 64. As a result, the central processing unit 53 outputs a sample music based on the sample signal from the speaker 64 to allow the user to sample it.

  Further, when the central processing unit 53 detects the end of the reproduction process for the trial listening data via the data processing unit 60, the central processing unit 53 newly identifies one trial listening music piece according to the arrangement of the list in the trial listening music list information 110. The information is automatically selected as noticeable audition music identification information. Then, the central processing unit 53 requests corresponding sample data from the music data distribution server SV1 in accordance with the sample music identification information newly selected as the target sample music identification information. As a result, when the trial data is transmitted from the music data distribution server SV1 in the streaming format, the central processing unit 53 receives the trial data through the network interface 62 and the communication processing unit 61 in order and converts the trial data into the trial data. On the other hand, after the reproduction processing is performed by the data processing unit 60, the audio processing unit 63 performs the audio processing, and sends the obtained audition signal to the speaker 64. As a result, the central processing unit 53 outputs a sample music based on the sample signal from the speaker 64 to allow the user to sample it.

  In this way, each time the central processing unit 53 detects the end of the reproduction process for the sample data, the sample music identification information in the continuous sample list information 110 (that is, the collection identification information list 108) is sequentially identified as the target sample music identification. In addition to being automatically selected as information, corresponding sample data is acquired from the music data distribution server SV1 according to the sample music identification information selected as the target sample music identification information, and is streamed and reproduced. As a result, the central processing unit 53 allows the music selection image 70 according to the user operation until the user selects the desired music by appropriately changing the music selection images 70, 75, 80, 85, 88, 90 to 101. , 75, 80, 85, 88, 90 to 101, the continuous audition list information 110 is automatically generated, and a plurality of audition music pieces are continuously automatically generated in accordance with the generated continuous audition list information 110. It can be output and let the user audition. In addition, when the central processing unit 53 continuously outputs the sample music pieces continuously, the central processing unit 53 obtains a plurality of pieces of sample data corresponding to the plurality of pieces of sample music identification information in the continuous sample list information 110 so as to be repeated cyclically. Are automatically output sequentially and continuously.

  Incidentally, as a method of detecting the end of the reproduction process (that is, streaming reproduction) for the trial listening data in the central processing unit 53, for example, the following technique can be considered. However, it is not limited to such a method. First, the central processing unit 53 can detect the end of the reproduction process by managing the speaker 64 and a buffer in the data processing unit 60 located in the front stage of the interface for digital out. For example, the data processing unit 60 inputs the audition data (that is, linear PCM data) to the buffer, and inputs the audition data output from the buffer to the D / A converter in the audio processing unit 63 to thereby output the audition signal (that is, , Analog signal) and supplied to the speaker 64. In addition, the data processing unit 60, for example, temporarily inputs the trial listening data (that is, linear PCM data) output from the internal decoding processing unit to a buffer in the interface controller, and digitally outputs the trial listening data output from the buffer. Are converted into a format corresponding to the transmission protocol of the above, output from the interface controller, and digitally output through the interface. That is, the central processing unit 53 detects the end of the reproduction process of the trial data by detecting that the trial data has been written to the buffers and all the trial data written in the buffer has been read. .

  By the way, the central processing unit 53 detects the current time code during reproduction when the end time code is present in the sample data, and when the current time code matches the end time code, the reproduction process of the sample data ends. It can also be determined that it has occurred. Further, when the central processing unit 53 detects the current time code during reproduction of the trial listening data and detects that the current time code has stopped for a predetermined time, it can also determine that the reproduction processing of the trial listening data has been completed. Furthermore, when the central processing unit 53 detects that the level of the sample data being reproduced has remained below the predetermined value during the reproduction of the sample data for a predetermined time, the reproduction process of the sample data has been completed. It can also be determined.

  In addition to this, the central processing unit 53 accesses the purchase page address of the music purchase page information among various operation keys of the operation input unit 50 according to the continuous audition list information 110 (that is, requests acquisition of the music purchase page information). ) A purchase page address corresponding to the trial data being played (that is, a purchase page address corresponding to the trial song identification information of the trial data being played back) is associated with a specific operation key for inputting the operation input signal. In this way, the purchase page address associated with the specific operation key is updated according to the trial listening data being reproduced. Therefore, when the user operates a specific operation key while the trial data is sequentially played back by the data processing unit 60 according to the continuous trial list information 110, the central processing unit 53 responds accordingly at that time. In accordance with the purchase page address associated with the specific operation key, a page information request signal for requesting acquisition of music purchase page information is sequentially transmitted to the music data distribution server SV1 via the communication processing unit 61 and the network interface 62. As a result, when the central processing unit 53 receives the music purchase page information transmitted from the music data distribution server SV1 via the network interface 62 and the communication processing unit 61 in order, the central processing unit 53 is playing back to the display 58 as described above. The music purchase image corresponding to the trial listening data is displayed. Thus, the central processing unit 53 transitions between the music selection images 70, 75, 80, 85, 88, 90 to 101 when the user listens to the sample music and likes the original music and downloads the music data. Even if the corresponding music title is not selected and instructed, the music purchase image can be displayed and the download can be requested only by operating a specific operation key.

  However, the central processing unit 53 deletes the purchase page address associated with a specific operation key when the trial listening data is not reproduced in the data processing unit 60. When the specific operation key is operated by the user in a state where the purchase page address associated therewith is deleted, the central processing unit 53 does not accept the operation. Further, the central processing unit 53 silences (that is, mutes) the sample music output from the speaker 64 during the process of reproducing the sample data, and whether or not the speaker 64 is connected to the data storage / reproduction device 21 via the audio processing unit 63 It also detects whether or not. While the trial processing data is being reproduced, the central processing unit 53 detects that the trial music piece is not being output from the speaker 64 due to mute or the speaker 64 being disconnected. When operated, even if the purchase page address is associated with the operation key at that time, the operation is not accepted. As a result, when a specific operation key is operated while the sample music is being auditioned by the user, the central processing unit 53 displays a music purchase image corresponding to the sample music being auditioned on the display 58 to display the music. Although downloading of data is possible, even if a specific operation key is mistakenly operated when the sample music is not sampled by the user, it is necessary to obtain the music purchase page information according to the operation. It is avoiding. That is, the central processing unit 53 avoids downloading music data by mistake with this configuration.

  Incidentally, the central processing unit 53 determines whether or not the speaker 64 is connected to the data storage / reproduction device 21, for example, whether or not the connector provided on the speaker 64 is electrically connected to the corresponding connector of the data storage / reproduction device 21. It can be detected by monitoring. Further, the central processing unit 53 can detect whether or not the sample music is muted by monitoring the gain when controlling the amplifier in the audio processing unit 63. The central processing unit 53 does not delete the purchase page address to be associated with a specific operation key when the sample data is not being reproduced by the data processing unit 60, and holds it in advance in the data storage / reproduction device 21, for example. The network address associated with the specific operation key may be updated by associating the network address indicating the supply source of the notification page information for notifying that there is no music purchase page information to be acquired. The central processing unit 53 obtains notification page information from the outside according to the associated network address when a specific operation key is operated by the user when the sample processing data is not being reproduced in the data processing unit 60. At the same time, a notification image can be displayed on the display 58 based on the notification page information to notify the user that there is no music purchase page information to be acquired at this time.

  In practice, the central processing unit 53 executes a series of reproduction processes related to the generation of the continuous audition list information 110 and the continuous automatic output of the audition data according to the reproduction program stored in the hard disk of the ROM 54 or the hard disk drive 55. To do. However, in the case where the playback process is to perform playback processing of sample data corresponding to the sample music identification information at the time when the first or predetermined number of sample music identification information is collected according to preset setting information, the continuous sample list information 110 generation processing and trial listening data reproduction processing are executed simultaneously in parallel. Therefore, in the following, as the playback process, a continuous trial list generation process procedure showing a process for generating the continuous trial list information 110 and a trial data playback process procedure showing a process for playing the trial data will be described in order.

  First, when the central processing unit 53 detects that the uppermost music selection page information 32 transmitted from the music data distribution server SV1 has been taken in, the central processing unit 53 performs a first continuous audition list generation processing procedure RT1 shown in FIG. 16 according to the reproduction program. Start. When the central processing unit 53 starts the first continuous audition list generation processing procedure RT1, in step SP1, the page identification information included in the music selection page information 32 fetched from the music data distribution server SV1 and the collected used pages By comparing with the page identification information in the list, it is determined whether or not the music selection page information 32 is unused for collecting the sample music identification information. If an affirmative result is obtained in step SP1, this indicates that the music selection page information 32 has not been used yet for collection of trial-listening music identification information. Accordingly, the central processing unit 53 moves to the next step SP2 at this time.

  In step SP2, the central processing unit 53 collects the trial song identification information related to the keyword and the corresponding purchase page address from the genre list information 33 included in the song selection page information 32, and collects the collected trial song identification information and The corresponding purchase page address is added to the continuous trial listening list information 110, and the process proceeds to the next step SP3. In step SP3, the central processing unit 53 adds the page identification information included in the music selection page information 32 used to collect the trial song identification information at this time to the collected used page list, and proceeds to the next step SP4. Move.

  In step SP4, the central processing unit 53, based on the selected page address in the genre list information 33 included in the music selection page information 32 used for collecting the trial song identification information at this time, is more than the music selection page information 32. The number of pieces of music selection page information 32A and 32B one level lower (hereinafter referred to as the number of lower page information) n is set, and the process proceeds to the next step SP5. In step SP5, the central processing unit 53 lowers the music selection page information 32 used for collecting the trial song identification information at this time, and selects the music selection page information 32A that has not been used for collecting the trial song identification information. It is determined whether or not 32B exists. If a negative result is obtained in this step SP5, this is lower than the music selection page information 32 used for collecting the trial song identification information at this time, and has not yet been used for collecting the trial song identification information. This indicates that the music selection page information 32A and 32B exist. Therefore, the central processing unit 53 moves to step SP6 at this time.

  In step SP6, the central processing unit 53 requests the corresponding music selection page information 32A or 32B from the music data distribution server SV1 in accordance with the selection page address in the genre list information 33 included in the highest-order music selection page information 32. To do. As a result, when the central processing unit 53 detects the incorporation of the music selection page information 32A or 32B, the central processing unit 53 sequentially executes the same processing as the processing of step SP1 to step SP3 described above. That is, the central processing unit 53 compares the page identification information included in the music selection page information 32A or 32B fetched from the music data distribution server SV1 with the page identification information in the collected used page list to select the music. It is determined whether or not the page information 32A or 32B is unused for collecting the sample music identification information. As a result, if it can be confirmed that the music selection page information 32A or 32B has not yet been used for collecting the sample music identification information, the artist list information 39A and 39B included in the music selection page information 32A or 32B can be continued. The sample music identification information related to the keyword and the corresponding purchase page address are collected and added to the continuous sample list information 110. The central processing unit 53 adds the page identification information included in the music selection page information 32A or 32B used for collecting the trial song identification information at this time to the collected used page list, and proceeds to the next step SP7. Move.

  In step SP7, the central processing unit 53 updates the lower page information number n by subtracting 1 from the lower page information number n set in step SP4, and returns to step SP5. Thereby, the central processing unit 53, when a plurality of music selection page information 32A and 32B exist below the music selection page information 32 used for collecting the trial music identification information in step SP2, the steps SP5-SP6-SP7-SP5. By repeating the above process cyclically, the trial-listening music list information 110 and the corresponding purchase page address are sequentially collected from all the lower-level music selection page information 32A and 32B, and the continuous trial-list list information 110 is updated.

  If an affirmative result is obtained in step SP5, this means that all the music selection page information 32A and 32B lower than the music selection page information 32 used for collecting the trial music identification information in step SP2 are used as the trial music identification information. Indicates that it has been used for collection. Alternatively, the positive result indicates that the music selection page information 32A and 32B are not present lower than the music selection page information 32 used for collecting the trial song identification information in step SP2. Therefore, the central processing unit 53 moves to step SP8 at this time, and ends the first continuous audition list generation processing procedure RT1.

  By the way, the central processing unit 53 collects the trial song identification information using the keyword and collects the music selection page information up to a predetermined level only by executing the first continuous trial listening list generation processing procedure RT1 once. If it is not possible to use, the first continuous trial listening list generation processing procedure RT1 is executed again, and the music selection page information up to a predetermined level is used to collect the trial music identification information and the corresponding purchase page address and continuously. The trial listening list information 110 is updated. However, when the central processing unit 53 newly executes the first continuous audition list generation processing procedure RT1, in step SP1 at that time, the central processing unit 53 executes the first continuous audition list generation processing procedure RT1 before the execution. The music selection page information used for collecting the trial song identification information in step SP6 is again set as the use target of the collection of the trial song identification information. For this reason, when the central processing unit 53 executes the first continuous trial listening list generation processing procedure RT1 after the second time, the page identification information of the music selection page information to be used for collecting the trial music identification information in step SP1. Is already registered in the collected used page list, it is determined that the music selection page information has already been used for collecting the trial song identification information according to the collected used page list, and the process proceeds to step SP4. . Therefore, when the central processing unit 53 executes the first continuous audition list generation processing procedure RT1 twice or more, in the second and subsequent processes, the central processing unit 53 substantially executes the processing of step SP4 to step SP8 in sequence. The music selection page information up to 1 can be used for collecting the audition music identification information in a single layer, and the serial audition list information 110 can be updated by collecting the audition music identification information and the corresponding purchase page address. .

  When the central processing unit 53 finishes collecting the trial song identification information and the purchase page address using the keywords from the song selection page information up to a predetermined hierarchy, the same reference numerals are assigned to the corresponding parts in FIG. The second continuous audition list generation processing procedure RT2 shown in FIG. 17 is started. When the central processing unit 53 starts the second continuous trial listening list generation processing procedure RT2, in step SP1, the central processing unit 53 executes the first continuous trial listening list generation processing procedure RT1 and performs the lowest order used for collecting the trial song identification information. Whether or not the music selection page information is unused in the collection of the trial listening music identification information by comparing the page identification information included in the music selection page information with the page identification information in the collected used page list Is determined. In this case, the central processing unit 53 obtains a negative result because the page identification information included in the music selection page information has already been registered in the collected used page list. For this reason, the central processing unit 53 skips the processing of step SP11 and step SP3 at this time, and moves to step SP4. The central processing unit 53 proceeds to step SP5 through the process of step SP4 in the same manner as the first continuous audition list generation process procedure RT1 described above. However, if a negative result is obtained in step SP5, the central processing unit 53 proceeds to step SP12.

  In step SP12, the central processing unit 53 corresponds to the music data distribution server SV1 according to the selected page address in the music list information 45A to 45B (or artist list information 39A and 39B) included in the music selection page information used in step SP1. Request one piece of music selection page information. As a result, when the central processing unit 53 detects the incorporation of the music selection page information, the central processing unit 53 sequentially executes the same processing as the processing of steps SP1-SP11-SP3 described above. That is, the central processing unit 53 first compares the page identification information included in the music selection page information fetched from the music data distribution server SV1 with the page identification information in the collected used page list as in step SP1. It is determined whether or not the music selection page information is unused for collecting the sample music identification information. As a result, if it can be confirmed that the music selection page information has not yet been used for collecting the sample music identification information, the same processing as in step SP11 is continued. In this case, the central processing unit 53 collects all the audition music identification information and the corresponding purchase page address from the music list information 45A to 45B (or artist list information 39A and 39B) included in the music selection page information. The collected listening music identification information and the corresponding purchase page address are added to the continuous listening list information 110. Then, the central processing unit 53 adds the page identification information included in the song selection page information used for collecting the trial song identification information at this point to the collected used page list in the same manner as in step SP3, and the next step Move to SP7.

  In this way, the central processing unit 53 cyclically and repeatedly executes the processing of steps SP5-SP12-SP7-SP5 when a plurality of music selection page information exists below the music selection page information used in step SP1. Thus, the trial listening list information 110 is updated by sequentially collecting the trial listening music identification information and the corresponding purchase page address from all the music selection page information of the lower order. If the central processing unit 53 obtains a positive result in step SP5, the central processing unit 53 proceeds to the next step SP13 and ends the second continuous audition list generation processing procedure RT2.

  By the way, when there are a plurality of lowest music selection page information used for collecting the trial song identification information in the execution of the first continuous trial listening list generation processing procedure RT1, the central processing unit 53 has the lowest music selection page information. The second continuous audition list generation processing procedure RT2 is executed as many times as When the second continuous audition list generation processing procedure RT2 is executed in this way, the lowest music selection page information is used in order in step SP1. Further, the central processing unit 53 performs the second consecutive trial listening list generation processing procedure RT2 so as to sequentially use the lowest music selection page information in step SP1, and collects trial listening music identification information in a predetermined hierarchy ( For example, if the music selection page information up to the lowermost layer) cannot be used, the second continuous audition list generation processing procedure RT2 is further executed, and the music selection page information up to a predetermined hierarchy is stored in one hierarchy. Used to collect the trial song identification information, the trial song identification information and the corresponding purchase page address are collected and the continuous trial list information 110 is updated.

  However, even when the central processing unit 53 sequentially executes the second continuous audition list generation processing procedure RT2 using the music selection page information up to a predetermined hierarchy in this way, in step SP1, before the execution, the second processing list generation processing procedure RT2 is executed. The music selection page information used for collecting the trial song identification information in step SP12 when the continuous trial list generation process procedure RT2 is executed again is used as the collection target of the trial song identification information. Therefore, as in the case of the first continuous trial list generation processing procedure RT1, the central processing unit 53 is set to be used for collection of the trial song identification information in step SP1 of the second continuous trial list generation processing procedure RT2. Since the page identification information of the music selection page information has already been registered in the collected used page list, according to the collected used page list, the music selection page information has already been used for collecting the trial song identification information. And the process proceeds to step SP4. That is, when the central processing unit 53 executes the second continuous audition list generation processing procedure RT2 following the first continuous audition list generation processing procedure RT1, the central processing unit 53 substantially executes the processing of step SP4 to step SP13 sequentially. The music selection page information up to a predetermined hierarchy (for example, the lowest layer) is used without any exception in one hierarchy, and the trial listening music identification information and the corresponding purchase page address are collected to update the continuous audition list information 110. it can.

  Further, the central processing unit 53 collects the first or specified number of sample music identification information from all the music selection page information 32, 32A to 32BA as specified in the setting information, and all the music When the collection of the sample music identification information from the selected page information 32, 32A to 32BA is completed, the sample data reproduction processing procedure RT3 shown in FIG. 18 is started according to the reproduction program. When the central processing unit 53 starts the trial data reproduction processing procedure RT3, in step SP21, the central processing unit 53 follows, for example, a list of the plurality of trial music piece identification information in the continuous trial music list information 110 (that is, the collection identification information list 108). Then, it is determined whether or not there is sample music identification information to be selected as the sample music identification information of interest. If an affirmative result is obtained in this step SP21, this indicates that there is sample music identification information that has not yet been selected as the target sample music identification information in the continuous sample list information 110. Accordingly, the central processing unit 53 moves to the next step SP22 at this time.

  In step SP22, the central processing unit 53 automatically selects one of the plurality of pieces of sample music identification information in the continuous sample list information 110 as attention sample music identification information according to the arrangement of the list, and proceeds to the next step SP23. . In step SP23, the central processing unit 53 transmits a trial data request signal to the music data distribution server SV1 via the communication processing unit 61 and the network interface 62 in accordance with the trial music identification information selected as the target trial music identification information. As a result, the central processing unit 53 receives the corresponding audition data transmitted from the music data distribution server SV1 in a streaming format through the network interface 62 and the communication processing unit 61 in order, and then the data processing unit 60 and the audio processing unit. 63 are sequentially sent to the speaker 64 as a trial listening signal. As a result, the central processing unit 53 causes the user to make a trial listening by outputting a trial music piece based on the trial listening signal from the speaker 64. When the central processing unit 53 detects the end of the reproduction process for the trial listening data via the data processing unit 60, the central processing unit 53 returns to step SP21.

  Accordingly, the central processing unit 53 thereafter repeats the processing of steps SP21-SP22-SP23-SP21 in a cyclic manner until a negative result is obtained in step SP21, whereby a plurality of trial listening in the continuous listening list information 110 is obtained. While the music identification information is automatically and sequentially selected as the attention audition music identification information, the audition data corresponding to the audition music identification information selected as the attention audition music identification information is continuously acquired from the music data distribution server SV1 as the audition music. Automatically output to By the way, if a negative result is obtained in step SP21 described above, this means that all the audition music identification information in the continuous audition list information 110 is selected as the attention audition music identification information, and the audition corresponding to all the audition music identification information is performed. This means that the data has been automatically output continuously as trial music. Therefore, the central processing unit 53 moves to step SP24 at this time, and ends the trial data reproduction processing procedure RT3. Then, even if the central processing unit 53 finishes outputting the audition data corresponding to all the audition music identification information in the continuous audition list information 110 as the audition music, if the user has not finished selecting the desired music, the central processing unit 53 again. The trial data reproduction processing procedure RT3 is executed.

  In this way, the central processing unit 53 cyclically and repeatedly acquires a plurality of pieces of sample data corresponding to a plurality of pieces of sample song identification information in the continuous sample list information 110 while the user selects a desired piece of music. It is possible to make the user audition the sample music. Incidentally, when the user finishes selecting the desired music piece during the execution of the trial listening data playback processing procedure RT3, the central processing unit 53 ends the trial listening data playback processing procedure RT3 at that time and performs continuous automatic processing for the listening music piece. The output is also terminated. The central processing unit 53 interrupts the continuous automatic output for the sample music when the sample music is arbitrarily selected by the user operation during the continuous automatic output for the sample music and the corresponding sample data is requested to be reproduced. Then, the audition data corresponding to the audition music arbitrarily selected by the user operation is reproduced. When the central processing unit 53 detects the end of the reproduction process of the sample data, the central processing unit 53 resumes continuous automatic output for the sample music using the continuous sample list information 110. When the central processing unit 53 resumes the continuous automatic output for the sample music, the central processing unit 53 resumes the output of the interrupted sample music from the head or the interruption position, or any sample music in the continuous sample list information 110. Output is resumed from the sample music corresponding to the identification information.

  Further, when the central processing unit 53 acquires the music purchase page information in response to a user operation during continuous automatic output for the trial music, the central music unit 53 can purchase the trial music that is automatically output at that time with the music purchase page information. If it corresponds to music data that can be downloaded (that is, downloadable), the sample music is repeatedly and automatically output as it is during the purchase process. When the central processing unit 53 detects the end of the purchase process and returns to the display of the music selection images 70, 75, 80, 85, 88, 90 to 101, the normal audition using the continuous audition list information 110 is performed. Return to continuous automatic output for music.

  On the other hand, when the central processing unit 53 obtains the music purchase page information, the trial music that is automatically output at that time is different from the trial music corresponding to the music data that can be purchased with the music purchase page information. During the purchase process using the music purchase page information, the automatic music output corresponding to the music data that can be purchased by the music purchase page information is automatically and repeatedly output during the purchase process using the music purchase page information. . When the central processing unit 53 detects the end of the purchase processing and returns to the display of the music selection images 70, 75, 80, 85, 88, 90 to 101 again, the central processing unit 53 responds to the trial listening music using the continuous listening list information 110. Resume continuous automatic output. When the central processing unit 53 resumes the continuous automatic output for the sample music, the central processing unit 53 resumes the output of the interrupted sample music from the head or the interruption position, or any sample music in the continuous sample list information 110. Output is resumed from the sample music corresponding to the identification information.

  In the above configuration, each time the data storage / playback device 21 takes in music data from a CD or music data distribution server SV1 and stores it in the hard disk, the stored music data is statistically processed by type to generate a keyword. In this state, when the data storage / reproduction device 21 detects the incorporation of the highest-order music selection page information 32 transmitted from the music data distribution server SV1 in response to a page acquisition request from the user, the highest-order music selection page information The collection identification information list 108 is created by collecting the sample music identification information related to the keyword from within 32. The data storage / playback device 21 also acquires, from the music data distribution server SV1, music selection page information 32A and 32B that can be transitioned from the highest-order music selection page information 32, and in the acquired music selection page information 32A and 32B. Also, the sample music identification information related to the keyword is collected and added to the collected identification information list 108. In this way, when the data storage / reproduction device 21 detects the incorporation of the uppermost music selection page information 32, the data storage / reproduction device 21 includes the uppermost music selection page information 32 and the music selection page information up to a predetermined hierarchy lower than this. The collected music identification information list 108 is created by collecting the sample music identification information related to the keywords from the above.

  Further, the data storage / playback device 21 continues to collect the music selection page information from the music data distribution server SV1 by one layer lower than the predetermined layer to the predetermined layer (for example, the highest layer) after the collection of the sample music identification information related to the keyword is completed. While sequentially collecting the music selection page information up to (lower order), all the sample music identification information is collected from the acquired music selection page information and added to the collection identification information list 108. Then, the data storage / playback device 21 automatically selects one piece of sample music identification information among the plurality of pieces of sample music identification information in the collected identification information list 108 as the target sample music identification information, and also includes the sample music identification information of interest. Is requested from the music data distribution server SV1. As a result, the data storage / playback device 21 takes in the corresponding audition data transmitted from the music data distribution server SV1 in a streaming format, and performs playback processing and audio processing to output it as trial music. In addition, when the data storage / reproduction device 21 detects the end of the reproduction process for the sample data, the new sample music identification information is newly selected from the plurality of sample music identification information in the collected identification information list 108. As well as requesting new music data corresponding to the sample music identification information selected as the target sample music identification information to the music data distribution server SV1. As a result, the data storage / reproduction device 21 takes in corresponding new trial data transmitted from the music data distribution server SV1 in a streaming format, performs reproduction processing and audio processing, and outputs them as trial music. In this way, the data storage / playback device 21 automatically and continuously outputs a plurality of sample data corresponding to the plurality of sample music identification information in the collection identification information list 108 as the sample music while sequentially obtaining from the music data distribution server SV1. To do.

  Therefore, when the data storage / reproduction device 21 detects the incorporation of the highest-order music selection page information 32 transmitted from the music data distribution server SV1 in response to a page acquisition request from the user, the music selection page information 32, 32A of a plurality of layers is detected. Collecting the trial song identification information from thirty-two BAs to create the collection identification information list 108, and sequentially fetching and playing a plurality of trial data corresponding to the plurality of trial song identification information in the created collection identification information list 108 In order to process, without causing the user to perform any operation for sequentially taking in the music selection page information 32, 32A to 32BA of a plurality of layers for selection of the trial music, or for selecting the trial music, etc. A plurality of music selection pages can be obtained only by performing an operation for taking in the highest-order music selection page information 32. Di information 32,32A to capture the preview data corresponding to the preview tune identification information in 32BA can reproduce process.

  According to the above configuration, when the data storage / playback device 21 detects the incorporation of the highest-order music selection page information 32, the trial-song music identification information is collected from the highest-order music selection page information 32 and the collected identification information is collected. While creating the list 108, the music selection page information 32A to 32BA lower than the highest-order music selection page information is automatically acquired, and the sample music identification information is also acquired from the acquired music selection page information 32A to 32BA. Collected and added to the collection identification information list 108, and a plurality of pieces of trial data corresponding to the plurality of pieces of trial song identification information in the collection identification information list 108 thus created are sequentially fetched and reproduced. As a result, the data storage / playback device 21 allows the user to perform only the operation for taking in the highest-order music selection page information 32, and to add the trial music identification information in the plurality of music selection page information 32, 32A to 32BA. Corresponding sample data can be captured and played back. As a result, the data storage / reproduction device 21 can remarkably simplify the operation at the time of reproducing the audition data.

  Further, when the data storage / reproduction device 21 collects the first sample music identification information from the music selection page information 32, 32A to 32BA according to the setting information, the data storage / reproduction device 21 takes in the sample data corresponding to the collected sample music identification information. However, in the case of performing the reproduction process, the reproduction process for the trial listening data can be started at the earliest possible time after detecting the incorporation of the highest-order music selection page information 32. Therefore, the data storage / playback device 21 can start listening to the sample music without waiting for the user as much as possible when the top music selection page information 32 is taken in. In addition to this, when the data storage / playback device 21 collects a predetermined number of pieces of trial song identification information from the music selection page information 32, 32A to 32BA according to the setting information, the trial listening corresponding to the collected trial piece song identification information is collected. Even when data is played back while being played back, by selecting the prescribed number as small as possible, when the top-most music selection page information 32 is loaded as described above, the user can listen to the sample music without waiting for the user as much as possible. You can start listening.

  By the way, as described above with reference to FIG. 18, the data storage / playback device 21 performs the trial listening data playback processing procedure RT3, before the desired music is selected by the user, in the collection identification information list 108 to be noticed trial listening music identification information. When there is no unselected trial song identification information, the trial data reproduction processing procedure RT3 is once ended and the trial data reproduction processing procedure RT3 is executed again. For this reason, the data storage / playback apparatus 21 does not include much sample music identification information corresponding to the sample music data for the music selection page information 32, 32A to 32BA of a plurality of layers, and therefore collects one sample music identification information. When the period from the collection of one piece of the trial song identification information to the other is relatively long, when the trial data reproduction processing procedure RT3 is repeatedly executed, it is relatively The audition data corresponding to the trial song identification information collected at an earlier time point has a larger number of times of reproduction processing, and also corresponds to the trial song identification information collected at a later time point from the detection of the incorporation of the top music selection page information 32. There is a possibility that the number of times of reproduction processing is reduced as the sample data is received. That is, in such a case, in the data storage / reproduction device 21, the number of trial listening increases as the trial music corresponding to the trial music identification information collected at a relatively early point in time from the detection of the incorporation of the top music selection page information 32. On the other hand, the number of trial songs corresponding to the trial song identification information collected at a relatively late time from the detection of the incorporation of the highest-order music selection page information 32 decreases, and the user can repeatedly listen to the same trial song. It may cause a feeling of being. However, in the data storage / playback apparatus 21, when the collection of the trial song identification information from the music selection page information 32, 32A to 32BA is completed in accordance with the setting information, the trial listening data corresponding to the collected trial song identification information is being taken in. Since the playback process may be performed according to the setting information, when the trial data playback processing procedure RT3 is executed, the difference in time when a plurality of pieces of trial music identification information is collected from the music selection page information 32, 32A to 32BA of a plurality of layers is used. As a result, it is possible to avoid a difference in the number of times of trial listening of the trial listening music corresponding to the individual listening music identification information. In other words, the data storage / playback device 21 can select a desired music piece while listening to a plurality of trial music pieces almost equally without giving the feeling that only the same sample music piece is repeatedly heard.

  Further, when executing the sample data reproduction processing procedure RT3, the data storage / reproduction device 21 selects one sample music identification information among the plurality of sample music identification information in the collected identification information list 108 as attention sample music identification information, When sample data corresponding to the sample music identification information selected as the target sample music identification information is captured and reproduced, and the end of the reproduction process for the sample data is detected, a plurality of sample music identification information in the collection identification information list 108 is detected. In such a manner, one piece of sample music identification information is automatically selected as the target piece of test piece music identification information, and a plurality of pieces of sample data corresponding to the plurality of pieces of sample music identification information in the collected identification information list 108 are sequentially fetched. Multiple playback samples based on multiple pieces of sample data can be played continuously without bothering the user. And automatic output can be listening to.

  Further, the data storage / playback device 21 cyclically and repeatedly plays back a plurality of pieces of trial listening data corresponding to a plurality of pieces of viewing music identification information in the collected identification information list 108. It is possible to prevent the trial listening music from being lost after the trial data reproduction process is finished.
