  In response to a request from the air check device 80, the music distribution server 15 transmits release information RI to the air check device 80.

[FM tuner and PC (air check device)]
Referring to FIG. 8, air check device 80 includes a PC 13 and an FM tuner 14. The FM tuner 14 receives an FM broadcast. The PC 13 includes an ADC (Analog to Digital Converter) 31 that converts an analog signal output from the FM tuner 14 into a digital signal. The ADC 31 indicates, for example, a sound card. However, in the case of a digital tuner that can output a digital signal, the PC 13 may not include the ADC 31. The PC 13 is also installed with a general-purpose MP3 (MPEG Audio Layer-3) encoder 32, a general-purpose web browser 33, and a general-purpose MP3 player 17, and an air check program (38 to 40) described in detail later. The recording status management database 35, the index database 36, the cue sheet database 37, and the release information database 75 are constructed. The air check program includes an index generation module 38, a web interface 39, and an acquisition module 40. These details will be clarified in the following operation description.

Next, the operation of the air check device 80 will be described.
The FM tuner 14 and the PC 13 are always operating. Therefore, the FM tuner 14 always receives FM broadcasts, and the PC 13 records all received broadcast data in a storage medium (HDD 133).

  Referring to FIG. 9, the MP3 encoder 32 in the PC 13 is always operating, and encodes the digital broadcast data output from the FM tuner 14 and A / D converted into MP3 data (S301). In parallel with this, the web interface 39 also operates, and the MP3 data obtained by the MP3 encoder 32 is saved (recorded) in the MP3 database 34 as one MP3 file 42 every predetermined time (6 hours in this example) (S302). ).

  The web interface 39 also generates the recording situation management table 43 shown in FIG. 10 (S311) and stores it in the recording situation management database 35 (S312).

  Referring to FIG. 10, the recording status management table 43 includes a field 431 in which station IDs are described, and a plurality of records 432 corresponding to a plurality of MP3 files 42. Each record 432 describes the recording start time, recording end time, and file name of the corresponding MP3 file 42. FIG. 11 shows an example of the recording status management table 43.

  The file name of the MP3 file 42 is set to a combination of the station ID and the recording start time, for example, “OOSAKA_20050522180000.MP3” (MP3 is an extension indicating the MP3 file 42). The recording start time corresponds to the broadcast start time of the MP3 file (broadcast data), and the recording end time corresponds to the broadcast end time of the MP3 file. In short, the recording time coincides with the broadcast time.

  In principle, FM broadcasts are recorded for 24 hours every day. However, there is a case where a power failure occurs or the user turns off the power of the PC 13, so that all broadcast data is not necessarily saved as the MP3 file 42. For example, in FIG. 11, portions other than the hatched lines are not recorded.

  On the other hand, the index generation module 38 reads the MP3 file 42 from the MP3 database 34, generates the index file 44 based on the MP3 file 42 (S321), and stores it in the index database 36 (S322).

  Specifically, as shown in FIG. 12, the index generation module 38 divides the MP3 file 42 into a plurality of sections 45 every predetermined time. In this example, since the MP3 file 42 for 6 hours is divided every second, 21600 (= 6 hours × 60 minutes × 60 seconds) sections 45 are obtained. Then, the index generation module 38 writes the start address of each section 45 in the index file 44 in order.

  FIG. 13 shows an example of the index file 44. The index file 44 has a field 441 describing station IDs and a plurality of records 442 corresponding to a plurality of sections 45. Each record 442 describes the start address of the corresponding section 45. In this example, the offset (relative address) from the head address of the MP3 file 42 is written as the start address.

  Although the elapsed time (seconds) from the beginning of the MP3 file 42 is shown in FIG. 13, this notation may be present, but it may not actually be present. This is because the elapsed time of each offset (record 442) can be calculated from the number of offsets before that offset.

  Further, the file name of the index file 44 is also set to, for example, “OOSAKA_20050522180000.IDX” (IDX is an extension indicating the index file 44) by combining the same station ID and recording start time as the corresponding MP3 file 42.

[Song information display processing]
Next, the music information display process executed by the PC 13 in the air check device 80 will be described. The air check device 80 lists only the new music out of the songs broadcast from the broadcasting station and displays it on the display 134. Thereby, the user can browse only the new music among the on-air songs. Further, the user can instruct reproduction of a desired song among the displayed songs and listen to the song.

  Referring to FIG. 14, the web interface 39 in the PC 13 requests the cue sheet 26 from the cue sheet server 12 every predetermined period (S401), and acquires the cue sheet 26 (S402). The acquired cue sheet 26 is stored in the cue sheet database 37.

  The web interface 39 requests the music distribution server 15 for music release information RI corresponding to the music information MI registered in the cue sheet 26 (S404). Specifically, the web interface 39 refers to the cue sheet 26 acquired in step S402, and reads specific information (for example, title name and artist name) of a plurality of pieces of music information MI included in the cue sheet 26. Then, the read specific information is transmitted to the music distribution server 15. When receiving the release information RI request command from the PC 13, the music distribution server 15 refers to the release information table 150 and extracts the release information RI corresponding to the transmitted specific information (title name and artist name). Then, the extracted release information RI is transmitted to the PC 13.

  By the above method, the web interface 39 acquires release information RI corresponding to the plurality of pieces of music information MI in the cue sheet 26 (S405). The acquired release information RI is stored in the release information database 75.

  The PC 13 that has acquired the cue sheet 26 and the plurality of release information RI searches for new music from the songs registered in the cue sheet 26 (search process: S406). Hereinafter, the search process will be described in detail.

  The web interface 39 sets the search number i = 1 (S407). Then, release information RI1 corresponding to the song information MI1 among the plurality of song information MI (hereinafter referred to as song information MI1 to MIn (n is a natural number)) registered at the head of the cue sheet 26 from the release information database 75. Read (S408). The web interface 39 determines whether or not the release date in the release information RI1 is within the search period that is the target of the new music (S409). The PC 13 stores the search period table shown in FIG. Referring to FIG. 15, a plurality of search periods are registered in the search period table. Each search period can be set by a user operation using the input device 135. The web interface 39 reads a search period corresponding to “new music” in the search period table. In the present embodiment, the web interface 39 is preset to use a search period corresponding to “new music” in the search period table in the process of step S406. After reading the search period, the web interface 39 determines whether the release date in the release information RI1 is included in the search period (S409). According to the example of FIG. 15, the web interface 39 determines whether or not the release date in the release information RI1 is included in the current date ± 30 days.

  If the release date is not included in the search period (NO in S409), the process proceeds to step S411. On the other hand, when the release date is included in the search period (YES in S409), the web interface 39 stores the release information RI1 and the corresponding song information MI1 in the memory 132 (S410). If the process of step S409 is not performed for all the pieces of music information MI1 to MIn registered in the cue sheet 26 (NO in S411), the search number i is incremented (S412), and the process returns to step S408. In short, the web interface 39 executes the search process in step S409 for all the music information MIn registered in the cue sheet 26.

  When the search in step S409 is executed for all the music information MI1 to MIn registered in the cue sheet 26 (YES in S411), the web interface 39 uses the music information MI and the release information RI stored in the memory 132. Read song specific information. The web interface 39 reads, for example, music specific information (title name, artist name, etc.). Then, the web interface 39 further reads the release date of the song corresponding to the song information MI from the release information RI. Further, corresponding image data is acquired based on the image URL in the release information RI. Then, these data are supplied to the web browser 33.

  The web browser 33 receives various pieces of information including song specific information from the web interface 39 and displays them on the display 134 (S415). For example, the web browser 33 displays the title name, artist name, release date, and images related to the song in a list. Thereby, the user can browse the list of information on the new music on the display 134 among the songs broadcast from the broadcasting station.

  The user can listen to a desired new score from a plurality of new scores displayed on the display 134 as a list. The user uses the input device 135 such as a mouse to designate a desired song from among the displayed new scores. For example, when the user clicks on a desired song with the mouse, the web browser 33 designates the desired song according to the input operation (YES in 416), and issues a query to the web interface 39 to read the song. To do. In response to this query, the web interface 39 extracts data of the designated song from the MP3 database 34 (S417). The extraction method is as follows.

  The web interface 39 refers to the cue sheet 26 in the cue sheet database 37 and specifies the music information MIn corresponding to the designated music. Then, the broadcast time (broadcast start time begin and broadcast end time end) of the specified music information MIn is extracted. Then, the web interface 39 refers to the recording status management table 43 having the same station ID as the station ID in the cue sheet 26 and identifies the file name of the corresponding MP3 file 42. At this time, the web interface 39 specifies the file name of the MP3 file 43 including the broadcast time of the song MIn between the recording start time and the recording end time in the recording status management table 43. Further, the web interface 39 reads the index file 44 corresponding to the specified file name, refers to the read index file 44, and broadcast time (from the broadcast start time begin to the broadcast end time end in the music information MIn). MP3 data corresponding to (time) is extracted (S417).

  The web interface 39 passes the extracted MP3 data to the web browser 33. The web browser 33 activates the MP3 player 17, and the MP3 player 17 plays the designated song based on the MP3 data (S418).

  As described above, FM broadcasts are recorded for 24 hours in principle. However, since there is a case where a power failure occurs or the user turns off the power of the PC 13, not all broadcast data is necessarily saved as the MP3 file 42. . For this reason, there may be a case where the songs in the new music list displayed on the display 134 are not actually recorded.

  In order to prevent such a situation, the display 134 can be set to display only songs that have already been recorded as new music. This setting is input by a user operation using the input device 135, and the display conditions are stored in the HDD 133 in advance.

  After executing the search process of step S406, the web interface 39 refers to the display conditions stored in the HDD 133 and determines whether or not the setting is to display only the recorded music (S413). The operation when it is not set to display only the recorded music (NO in S413) is as described above. If it is set to display only the recorded song (YES in S413), the web interface 39 sets the song data among the plurality of song information MI and release information RI stored in the memory 132 in step S410 as MP3 file database. What is stored in 34 is specified (S414). The specifying process in step S414 is as follows.

The web interface 39 reads the broadcast time of the song information MI stored in the memory 132 in step S410 (S450). Then, with reference to the recording status management table 43 having the same station ID as the station ID of the cue sheet 26, it is determined whether or not there is an MP3 file 42 that includes the broadcast time of the read music information MI in the recording time. (S451). When the MP3 file 42 in which the broadcast time is included in the recording time exists (YES in S451), the corresponding music information MI is specified (S452). For example, the web interface 39 stores the song information MI specified in step S452 in a memory area different from that in step S410. The web interface 39 executes steps S450 and S451 for all the song information MI stored in step S410 (S453).
When step S414 is completed, the web interface 39 passes data such as the specific information of the music information MI specified in step S452 to the web browser 33, and the web browser 33 displays the data on the display 134 (S415). By the above method, only new music can be displayed on the display 134 from the recorded songs.

  With the above operation, the user can easily browse the list of new tunes on the display 134 from the broadcasted songs, and can easily listen to the songs by designating a desired song from among them. Can do. Even if a song is specified, a situation where no song is recorded can be avoided.

  In the above description, the cue sheet 26 is used to display the new music list on the display 134. However, the list displayed on the display 134 is not limited to the new music. As shown in FIG. 15, various search periods are registered in the search period table, and the setting of the search period can be added and changed according to the user operation. For example, if the user wants to list and display songs from the cue sheet 26 in the 1970s, the web interface 39 sets the search period to “70's” as the search period (1970). January 1 to December 31, 1979). Then, when the process shown in FIG. 14 is executed, a list of songs released in the 70s is displayed on the display 134.

  The operations in steps S101 to S113 in FIG. 18 are the same as those in FIG. The cue sheet editing unit 22 executes a search process using the release information RI received in step S113 and the cue sheet 26 (S406). The search processing operation is the same as the search processing (S406) in FIG. The cue sheet server 120 stores the search period table shown in FIG. 15. When searching for a new score, the cue sheet server 120 uses the search period corresponding to the name “new score” in FIG. The searched music information MI and the corresponding release information RI are stored in the memory 132 in the cue sheet server 12.

  After the search process is completed, the cue sheet editing unit 22 creates a cue sheet 30 including the song information MI and the release information RI stored in the memory 132 by the search process (S120). That is, the cue sheet 30 is a cue sheet limited to new music among the broadcasted songs. The created cue sheet 30 is stored in the cue sheet database 28 (S121).

  When the PC 13 acquires the cue sheet 30 created by the operation of FIG. 18, the music information display process is as shown in FIG. Referring to FIG. 19, when PC 13 acquires cue sheet 30 (S402), PC 13 can already display a new score on display 134. Therefore, it is sufficient for the PC 13 to execute the processes after step S413.

  In short, the search process (S406) may be executed by the PC 13 or the cue sheet server 120. Further, instead of the PC 13 and the cue sheet server 120, the music distribution server 15 may execute. In this case, the music distribution server 15 includes a cue sheet editing unit 22, acquires a cue sheet from the cue sheet server 12 or the broadcast station server 16, and executes a search process. Then, the PC 13 accesses the music distribution server 15 and acquires the cue sheet 30 created after the search process. The operation of the PC 13 after obtaining the cue sheet 30 is the same as in FIG.

  In the above embodiment, the broadcast content is music (music). However, the present invention can be applied not only to music but also to other contents such as video, and whether or not the data is compressed is not limited. That is, the form of broadcast data including content is not limited to FM radio, but may be satellite broadcast such as AM radio, Internet radio, TV (analog / digital), CS / BS (analog / digital).

  In the above embodiment, the PC 13 and the FM tuner 14 always operate and receive and record all broadcasts. However, in order to avoid wasting a limited storage area, a weekly schedule is set. It is possible to stop the operation at night when there is no broadcast, or detect the audio or video signal that has been broadcast and operate only when there is a broadcast, and stop the operation when there is no broadcast Good.

  In the above embodiment, the FM tuner 14 and the PC 13 constitute the air check device 80. However, an integrated dedicated machine that receives FM broadcasts and records them on the hard disk may constitute the air check device.

  In the above embodiment, the cue sheet server 12 obtains a cue sheet provided from a broadcasting station. However, the operator of the cue sheet server 12 directly inputs the cue sheet to the cue sheet server 12 and inputs the cue sheet server 12. May be stored.

  In the above embodiment, the PC 13 obtains the cue sheet provided from each broadcasting station via the cue sheet server 12, but may obtain it directly from each broadcasting station. Specifically, the acquisition module 40 shown in FIG. 8 directly accesses each broadcasting station server 16 instead of the cue sheet server 12.

  In the above embodiment, the broadcast data is transmitted by wireless broadcasting, but may be transmitted by cable broadcasting or may be transmitted via an electric communication line such as the Internet. In order to receive broadcast data via the Internet, a broadcast data acquisition module (not shown) may be provided in the PC 13 in place of the FM tuner 14, ADC 31 and MP3 encoder 32 shown in FIG. The broadcast data acquisition module accesses the broadcast station server 16 and requests to transmit broadcast data uploaded in a state where it can be acquired (or broadcast data distributed as a real-time stream). Since the broadcast station server 16 returns broadcast data in response to this request, the broadcast data acquisition module receives the returned broadcast data and stores it in the MP3 database 34. In short, the broadcast data acquisition module downloads broadcast data from the broadcast station server 16.

  In the above-described embodiment, the PC 13 reproduces the MP3 data of the extracted music on the MP3 player 17, but the PC 13 may transmit the extracted MP3 data to a user's portable terminal (not shown), for example. . In this case, MP3 data can be reproduced by an MP3 player mounted on the portable terminal. Therefore, for example, the user can listen to a desired song on the go using the mobile terminal.

  For example, as shown in FIG. 20, only the search start time can be registered or only the search end time can be registered as the search period of the search period table described above. When only the search start time is registered, the search period is all periods after the search start time. For example, as in the search period corresponding to the name “new music” in FIG. 20, only the search start time (current date −30 days) is registered, and the current date is 2008 5 When it is the 31st of the month, the search period is all periods after May 1, 2008. On the other hand, when only the search end time (December 31, 1970) is registered, as in the search period corresponding to “Hello” in FIG. 20, the search period includes all the periods before December 31, 1970. It becomes a period.

In the above-described embodiment, the music information MIn (n is a natural number) in the cue sheet includes the broadcast start time begin [n] and the broadcast end time end [n] as information related to the broadcast time. Only time begin [n] may be included. In this case, the broadcast time of the song specified by the song information MIn-1 broadcasted immediately before the song information Mn is broadcast of the song information MIn from the broadcast start time begin [n-1] of the song information MIn-1. The above-described processes are executed until the start time begin [n].
Moreover, the operation | movement of step S413-S418 as described in FIG.14 and FIG.19 in the above-mentioned embodiment is not essential, and is an arbitrary operation process.

  While the embodiments of the present invention have been described above, the above-described embodiments are merely examples for carrying out the present invention.
