  In step S4, the data processing unit 25 determines whether or not the recording end date / time is reached. When the recording end date / time is reached, the process proceeds to step S5. When the recording end date / time is not reached, the data processing unit 25 repeats step S4. To continue. In step S5, when the recording end date / time is reached, the data processing unit 25 stops driving the radio receiving unit 23 and stops the radio broadcast recording operation.

  In step S6, when the user inputs a predetermined URL (uniform resource location), for example, by operating the operation unit 27, the data processing unit 25 records the recorded broadcast channel data, recording start date / time data, and recording end date / time data. Is transmitted from the transmission unit 22 to the server device 10 together with the user identification data.

  In step S <b> 7, the server device 10 receives the user identification data, channel data, recording start date / time data, recording end date / time data, and the like transmitted from the terminal device 20 by the receiving unit 11. Next, the determination unit 15 of the server device 10 accesses the user registration record that configures the database of the recording unit 13 based on the user identification data transmitted from the terminal device 20, and determines whether or not the user is a registered user. to decide. Then, when the determination unit 15 is a registered user, the process proceeds to step S8. When the determination unit 15 is not a registered user, for example, the use of the system 1 notifies the user that user registration is necessary.

  In step S <b> 8, the search unit 16 of the server device 10 accesses the database of the storage unit 13 and performs a search based on the channel data, the recording start date / time data, and the recording end date / time data transmitted from the terminal device 20. . In step S9, the search unit 16 extracts corresponding data and creates a playlist as shown in FIG.

  This playlist is the broadcast start date and time and end date and time of the music data used in at least the broadcast in the time zone channel transmitted from the terminal device 20 so that the broadcast time of the broadcast music data can be specified. And identification data of music data.

  And the search part 16 transmits a play list to the terminal device 20 from the transmission part 12 in step S10. In step S <b> 11, when the terminal device 20 receives the data at the receiving unit 21, the data processing unit 25 stores the playlist in the storage unit 24.

  Further, as described above, when the broadcast data includes identification data of music data used for a program or identification data of a performer, the terminal device 20 creates a playlist based on the identification data. It may be. This will be described with reference to FIG. 6. In step S11, the terminal device 20 sets a timer for recording a radio broadcast. That is, when the user operates the operation unit 27, a radio broadcast channel to be recorded, a recording start date and time, and a recording end date and time are set, and these data are temporarily stored in the storage unit 24. In step S12, the data processing unit 25 determines whether or not the recording start date / time is reached based on the time input from the time supply unit 26. When the recording start date / time is reached, the process proceeds to step S13, where the recording start date / time is reached. If not, step S12 is repeated. In step S <b> 13, the data processing unit 25 drives the radio reception unit 23 to record the radio broadcast of the channel selected by the user in the storage unit 24 when the recording start date / time is reached.

  In step S14, the data processing unit 25 determines whether or not the recording end date / time is reached. When the recording end date / time is reached, the process proceeds to step S15. When the recording end date / time is not reached, the data processing unit 25 repeats step S14. To continue. In step S15, when the recording end date / time is reached, the data processing unit 25 stops driving the radio receiving unit 23 and stops the radio broadcast recording operation.

  In step S16, the data processing unit 25 extracts music data identification data included in the broadcast data. The data processing unit 25 creates a playlist as shown in FIG. 5 and stores it in the storage unit 24.

  The terminal device 20 that has acquired the playlist creates a first management table that associates the music data included in the broadcast data recorded by the terminal device 20 with the playlist. This will be described with reference to FIG. For example, FIG. 7 is created based on the playlist shown in FIG. The data processing unit 25 refers to the recording start date and time and end date and time for each piece of music data in the playlist shown in FIG. 5 and specifies the area where the music data of the recorded broadcast data stored in the storage unit 24 is recorded. To do. That is, the data processing unit 25 specifies the time zone between the recording start date and time and the end date and time for each piece of music data in the playlist as an area in which the music data is recorded, and refers to the playlist in each area. The identification data of music data is given. In addition, the data processing unit 25 specifies an area where no music data is recorded as, for example, an area where conversation data, commercial data, or the like is recorded.

  For example, the data processing unit 25 specifies the time zone from 18: 00 to 18: 03 as the time zone during which the song data is broadcast, and specifies that the song data recorded here is “ABC”. Further, the data processing unit 25 specifies the time zone from 18:04 to 18:06 as the time zone during which the music data is broadcast, and specifies that the music data recorded here is “XYZ”.

  Next, a procedure for extracting music data from broadcast data stored in the storage unit 24 by the terminal device 20 will be described with reference to FIG. In step S21, the data processing unit 25 deletes the area where the music data shown in FIG. 7 is not recorded, that is, sets the TOC (table of contents) to a state without data. Thereby, only the music data in the recorded broadcast data can be read. Then, the data processing unit 25 creates a second management table as shown in FIG. 9 so that the music data can be read according to the playlist. In the second management table, link information is recorded for each piece of music data included in the recorded broadcast data. Since the playlist and the recorded broadcast data are separately stored in the storage unit 24, the link information associates the music data identification data with the music data, for example, by selecting the identification data. The music data indicated by the identification data can be reproduced.

  In step S <b> 22, the data processing unit 25 refers to the recording start date and time to search for the first recorded music data and to search for music data next thereto. That is, in the example of FIG. 9, the data processing unit 25 searches and extracts the first music data “ABC” and the second music data “XYZ”. In step S23, the data processing unit 25 determines whether or not the first music data and the music data subsequent thereto are the same. When the data processing unit 25 is the same, the data processing unit 25 proceeds to step S24. When the data processing unit 25 is not the same, the data processing unit 25 proceeds to step S25.

  In step S24, when the music data is duplicated, the data processing unit 25 increments the duplication number by 1, deletes the duplicate music data, that is, sets the TOC to the state of no data, and makes the data unreadable. To do. Specifically, the data processing unit 25 rewrites the link information of the corresponding music data in the second management table without a link. As shown in FIG. 10, since the music data “ABC” is broadcast twice from 18: 00 to 18: 03 and from 19: 00 to 19: 03, the data processing unit 25: 19: 00 to 19: The link information of the music data “ABC” of 03 is set to no link. Then, the data processing unit 25 increments the overlapping number of the music data “ABC” by one.

  In step S25, the data processing unit 25 refers to the music data identification data, the recording start date and time, etc., and determines whether there is next music data. The data processing unit 25 proceeds to step S26 when there is next music data, and ends the process when there is no next music data.

  In step S26, when the data processing unit 25 proceeds to the next music data, the data processing unit 25 returns to step S23 and again determines whether the next music data is duplicated. That is, the data processing unit 25 prevents a plurality of the same music data from being stored in the storage unit 24 so that the recording area of the storage unit 24 can be used effectively.

  By the way, in step S24, the number of overlapping music data is counted. This is an index indicating the degree of popularity of music data in addition to the effective use of the recording area of the storage unit 24. Become. This is because music data repeatedly broadcast is often popular music data. Therefore, in order to make it easier to select music data to be stored in the storage unit 24, the data processing unit 25 displays information related to music data on the display unit 28 in descending order. This will be described with reference to FIG. In step S31, the data processing unit 25 extracts the duplication number of each piece of music data, sorts the music data in order of the duplication number, and displays it on the display unit 28 in step S32. Here, the screen displayed on the display unit 28 will be described with reference to FIG. 12. In this screen 31, information on music data is displayed in a list with a rank assigned from the top in the order of the number of overlaps. Specifically, the screen 31 is provided with a list display unit 32 that displays a list of information related to music data. The list display unit 32 includes, for each piece of music data, music data identification data, broadcast start date and time, and broadcast end. The date and the name of the performer are displayed in order from the first place. In addition, a determination button 33 is provided for confirming the music data selected by the user.

  In step S <b> 33, the data processing unit 25 determines whether one or a plurality of music data has been selected in accordance with a user operation. Specifically, when the user selects one or more from the list displayed by operating the operation unit 27 while referring to the screen displayed on the display unit 28, the data processing unit 25 determines in step S34. , Highlight the selected field.

  In step S35, when the user clicks the determination button in the screen by operating the operation unit 27, the data processing unit 25 deletes data other than the selected music data in step S36, that is, cannot be accessed. Put it in a state. That is, the data processing unit 25 deletes the music data not selected by the user, that is, the music data determined to be unnecessary, so that only the music data desired by the user is left in the storage unit 24, and The recording area can be used effectively.

  According to the system 1 as described above, a broadcast of a predetermined channel is recorded for a predetermined time, for example, using a timer function, and then the server device 10 is accessed to obtain a playlist of music data in the recorded time zone. Only the desired music data can be stored in the storage unit 24 using this playlist. When the desired music data is selected, the music data to be stored in the storage unit 24 can be selected with reference to this order since the music data is displayed in the order of the music data broadcast a plurality of times on the display unit 28. Further, in this system 1, since unnecessary data, that is, commercial data, conversation data, and unselected music data in the recorded broadcast data are erased, a recording area of the finite storage unit 24 is provided. It can be used effectively.

  By the way, the series of processes described above performed by the server device 10 and the terminal device 20 can be performed not only by hardware but also by software. When a series of processing is performed by software, a program constituting the software is installed in a general-purpose personal computer, a one-chip microcomputer, or the like.
