Abstract

<P>PROBLEM TO BE SOLVED: To maintain the continuity of broadcast data when continuously playing back music by selecting the music from a music list by the operation of a user. <P>SOLUTION: On completion of the playback of the music selected from the music list by the user operation, the next music in a queue sheet is selected and played back, not that the next music in the music list is selected. Therefore, even when music to be played back first is selected from the music list, music described in the queue sheet is selected one after another, and accordingly, the continuity of the broadcast data to be played back is maintained. When the user desires the playback of music in order of the music list, a skip instruction is input by the user operation, and thus, based on the music list, either the next or the preceding music to the presently selected music can be selected and started to play back. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to an air check device that automatically acquires desired content from among a large number of content broadcast from a broadcasting station.

  In general, air check is to record content such as music and video broadcast on radio and television on a storage medium, and then play back the recorded content for later enjoyment. Widely used between.

  However, the viewer does not know when the desired content will be broadcast. For example, in FM radio broadcasting, it may be known in advance that a desired song is broadcast in a program, but since CM and DJ are included in the program, when the desired song is broadcast in the program I do not know until.

  In order to solve this problem, the following Patent Application 1 proposes an air check system that extracts a desired song using a cue sheet. In this air check system, an air check device installed at a user's home or the like acquires a cue sheet describing a broadcast start time, a title, and the like of a broadcasted song from a server. The air check device also always receives FM broadcasts and stores all received broadcast data. Then, referring to the cue sheet, a desired song is extracted from all the recorded broadcast data and reproduced.

  The air check device generates a song list in which the song names of the selected artist's songs are sorted in alphabetical order and alphabetical order, a song list in which the song names are sorted in order of the number of appearances on the cue sheet in a predetermined period, and the like. To display. When one song is selected from the song list by the user operation, the selected song is started to be played. When the selected song is played back, the next song of the song selected in the song list is automatically selected, and the selected song is played back. That is, songs are continuously reproduced in the order listed in the song list from the selected song.

  As shown in FIG. 14, it is assumed that song A, song B, song C, song D, song E, and song F are broadcast in this order in program 1. On the other hand, as shown in FIG. 16, in the song list, song C, song F, song A, song D, song B, and song E are arranged in this order. When the song B is selected from the song list by the user operation, the playback range of the song B is specified as 8: 12: 0 to 8:20:00, and the playback range data is read from the storage medium and played back. . When the reproduction of the song B is finished, next, 8:40:00 to 8:50:00 is specified as the reproduction range of the song E that is the next song of the song B in the song list, and the reproduction range is stored from the storage medium. Read and play the song data.

  The cue sheet describes the broadcast start time of the song but not the broadcast end time. That is, the broadcast end time of the song is the broadcast start time of the next song. Therefore, as shown in FIG. 14, the actual broadcast time of the song B is 8: 12: 0 to 8:17:00, but the playback range of the song B specified from the cue sheet is 8:12:00. ~ 8: 20: 00. From 8:17: 00 to 8: 20:00, the introduction of the next song C by DJ, etc. is broadcast, but it is identified as the song B and played. As a result, when the music B and the music E are continuously played back in the order of the music list, after the music B has been played back, the introduction of the music C by the DJ is played, and then the music E is played back continuously. Data will not be continuous.

  As shown in FIG. 14, for example, the reproduction range based on the cue sheet of the song D is 8:35:00 to 8:40:00, but the actual broadcast time is 8:34:30 to 8:39: It is 30. This is because the broadcast start time described in the cue sheet is described only in minutes. As a result, the first 30 seconds of the song D is not included in the playback range of the song D but is included at the end of the playback range of the song C. Therefore, when the song C is selected by the user operation from the song list, the introduction of the song D by the DJ is played after the song C is played back, and the song 30 is played after the first 30 seconds of the song D is played. The broadcast data that is started and played back is no longer continuous. Similarly, when the song A is selected from the song list, the introduction of the song B by DL is played after the playback of the song A, and then the playback starts from the 30th second of the song D. Data will not be continuous.

JP 2007-59035 A

  The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide air that can maintain the continuity of broadcast data when a song is selected from a song list by a user operation and the song is continuously played back. It is to provide a check device.

  An air check device according to a preferred embodiment of the present invention includes: a receiving unit that receives broadcast data including a plurality of contents broadcast from a broadcast station; a recording unit that records the received broadcast data on a storage medium; Acquisition means for acquiring a cue sheet in which specific information and broadcast start time of each content broadcast from the server are associated with each other, and a list of a plurality of contents recorded in the storage medium by the recording means, the cue sheet Based on the cue sheet, a list generation unit that generates a content list in which a plurality of contents are arranged in a different order from the first list, a first selection unit that selects a desired content from the content list in response to a user operation The playback range of the content selected by the first selection means or the second selection means described later is specified. Extraction means for extracting broadcast data in the specified reproduction range, reproduction means for reproducing the broadcast data extracted by the extraction means, and reproduction means finishes reproducing the broadcast data in the reproduction range specified by the extraction means And a second selection means for selecting from the cue sheet the next content selected by the first selection means or the second selection means described later.

  When the reproduction of the content selected from the content list by the user operation is completed, the next content in the content list is not selected, but the next content in the cue sheet is selected and reproduced. Accordingly, even when the content to be reproduced first is selected from the content list, the content is reproduced in the order described in the cue sheet, so that the continuity of the reproduced broadcast data is maintained.

  In a preferred embodiment, the air check device receives the skip instruction by a user operation when the reproduction unit reproduces broadcast data in the reproduction range specified by the extraction unit. A third selection unit that selects from the content list the next content selected by the selection unit or the second selection unit; and the extraction unit further includes the third selection based on the cue sheet. The playback range of the content selected by the means is specified, and broadcast data in the specified playback range is extracted.

  In this case, when the user desires to play back the content in the order of the content list, a skip instruction is input by a user operation, so that the next of the currently selected content or based on the content list The previous content is selected and playback can be started.

  In a preferred embodiment, the reproduction range specified by the extraction means based on the cue sheet includes the content and broadcast data other than the content.

  In this case, if the content is continuously played in the order of the content list, the disadvantage that the continuity of the broadcast data to be played is lost becomes particularly noticeable. Therefore, by continuously playing the content in the order of the cue sheets instead of the content list, The effect of maintaining the property becomes particularly remarkable.

  When music is selected from the music list by user operation and the music is continuously played back, the continuity of the broadcast data can be maintained.

[overall structure]
Referring to FIG. 1, an air check system 10 according to an embodiment of the present invention is for automatically acquiring a desired song from a radio frequency modulation (FM) broadcast, and is a queue connected to the Internet 11. A sheet server 12, a personal computer (PC) 13 connected to the Internet 11, and an FM tuner 14 connected to the PC 13 are provided. A plurality of broadcast station servers 16 are also connected to the Internet 11. The cue sheet server 12 is managed by a provider who provides this service, and the broadcast station server 16 is managed by a broadcast station which mainly broadcasts music programs and the like. The PC 13 and the FM tuner 14 are the property of the user who is the viewer.

  The cue sheet server 12 acquires a cue sheet from each broadcast station server 16 and provides it to the PC 13 of each user. The PC 13 functions as a client that can access the cue sheet server 12. The PC 13 and the FM tuner 14 constitute an air check device 80.

  The PC 13 is a general-purpose device and includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive (HDD), a display, an input device such as a keyboard and a mouse, and the like. An air check program described later is installed in the PC 13. The FM tuner 14 receives FM broadcasts from each broadcasting station and supplies the received broadcast data to the PC 13.

[Queue sheet server]
With reference to FIG. 2, the cue sheet server 12 includes an acquisition unit 20, a format conversion unit 21, a service information addition unit 22, and a web server 23. The acquisition unit 20 accesses each broadcast station server 16 and acquires the cue sheet 24 uploaded thereto.

  In the cue sheet 24 provided from each broadcasting station, the broadcast start time begin [n] of the broadcasted song Mn and metadata such as titles and artist names are described in HTML (Hyper Text Markup Language). . However, the format, such as the type of information described, the type of tag used, the order of description, etc., varies from broadcast station to broadcast station. The cue sheet 24 does not describe the broadcast end time of the broadcasted song Mn.

  The format conversion unit 21 converts the format of the acquired cue sheet 24 into a predetermined common format. The format conversion unit 21 has a plurality of conversion filters 25 corresponding to a plurality of types of formats. Each conversion filter 25 converts a corresponding format into a common format.

  The cue sheet 26 thus obtained has a common format. Specifically, as shown in FIG. 3, the cue sheet 26 includes a field 261 describing a station ID (identifier) assigned to each broadcasting station, and a plurality of songs corresponding to a plurality of songs broadcast from the broadcasting station. And a record 262.

  Each record 262 describes the broadcast start time begin [n], broadcast end time end [n], and metadata of the corresponding song Mn. The broadcast end time end [n] is obtained based on the broadcast start time, and is specifically the same as the broadcast start time begin [n + 1] of the song Mn + 1 broadcast after the song Mn. FIG. 4 shows an example of the cue sheet 26.

  Referring to FIG. 2 again, the service information adding unit 22 adds various predetermined service information to each cue sheet 26 converted into the common format. Various service information includes a URL (Uniform Resource Locator) of a website that sells CDs, DVDs, concert tickets, and the like that record broadcast songs, URLs of websites that sell digital data of the songs, banner advertisements, etc. is there. Therefore, the cue sheet server 12 can be a portal site for guiding users to various websites 27.

  The acquiring unit 20 further acquires a program guide 69 provided from each broadcasting station. The program table 69 includes the broadcast start time and broadcast end time of the broadcasted program, information about the program name, DJ and performers, and metadata such as the program homepage URL. Within each program, the above-mentioned plurality of songs are broadcast. That is, the program includes a plurality of songs.

  The format of the program guide 69 provided from each broadcast station differs from broadcast station to broadcast station, as is the case with cue sheets. Therefore, the format conversion unit 21 converts the acquired program guide into a predetermined common format. The program guide 70 thus obtained has a common format. An example of the obtained program table 70 is shown in FIG. The program table 70 includes a station ID, broadcast start time and broadcast end time of the broadcasted program, and metadata.

  In the web server 23, a cue sheet database 28 and a program guide database 71 are constructed. The cue sheet 29 to which various service information is added is stored in the cue sheet database 28, and the program guide 70 is stored in the program guide database 71. The web server 23 reads the cue sheet 29 and the program guide 70 in response to a request from the PC 13 and transmits them to the PC 13.

  Next, the operation of the cue sheet server 12 will be described with reference to FIG. The acquisition unit 20 requests each broadcast station server 16 to transmit the cue sheet 24 and the program guide 69 (S101). Each broadcasting station server 16 receives this request (S201), and transmits the cue sheet 24 and the program guide 69 to the cue sheet server 12 (S202). The acquisition unit 20 receives the cue sheet 24 and the program guide 69 (S102) and supplies them to the format conversion unit 21.

  The format conversion unit 21 converts the format of the cue sheet 24 into a common format, and creates the cue sheet 26 shown in FIGS. 3 and 4 (S103). At this time, the broadcast start time begin [n + 1] of the song Mn + 1 is described in the cue sheet 26 as the broadcast end time end [n] of the song Mn. The created cue sheet 26 is supplied to the service information adding unit 22.

  The service information adding unit 22 adds service information to the cue sheet 26 (S104), and stores the cue sheet 29 obtained thereby in the cue sheet database 28 (S105).

  The format conversion unit 21 further converts the format of the program guide 69 into a common format and creates the program guide 70 shown in FIG. 5 (S103). The created program guide 70 is stored in the program guide database 71 (S105).

[FM tuner and PC (air check device)]
Referring to FIG. 7, 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 15, as well as an air check program (38-41) described in detail later. The recording status management database 35, the index database 36, the cue sheet database 37, and the program guide database 75 are constructed. The air check program includes an index generation module 38, a web interface 39, an acquisition module 40, and a sweeper module 41. These details will be clarified in the following operation description.

  Next, operations of the FM tuner 14 and the PC 13 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 on a storage medium such as a hard disk.

  Referring to FIG. 8, 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. 9 (S311) and stores it in the recording situation management database 35 (S312).

  Referring to FIG. 9, the recording status management table 43 includes a field 431 describing station IDs 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. 10 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).

  In principle, FM broadcasts are recorded for 24 hours every day. However, since there is a case where a power failure occurs or a user takes out the PC 13, not all broadcast data is necessarily saved as the MP3 file 42. In FIG. 10, the portions other than the diagonal 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. 11, 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. 12 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.

  In FIG. 12, the elapsed time (seconds) from the beginning of the MP3 file 42 is shown, but this notation may be present, but not actually. 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.

  Referring to FIG. 13, the acquisition module 40 in the PC 13 requests the web server 23 of the cue sheet server 12 to transmit a desired cue sheet 29 and program guide 70 (S331). The web server 23 receives this request (S111), reads the desired cue sheet 29 from the cue sheet database 28, and reads the desired program table 70 from the program table database 71. Then, the read cue sheet 29 and program guide 70 are transmitted to the PC 13 (S112).

  The acquisition module 40 receives the cue sheet 29 and the program guide 70 transmitted from the cue sheet server 12 (S332). Then, the cue sheet 29 is stored in the cue sheet database 37, and the program guide 70 is stored in the program guide database 75 (S333).

  If necessary, the web interface 39 in the PC 13 edits the cue sheet 29 according to the user's input operation (S334). As a result, the user can shift the broadcast start time of the desired song before or after the specified time, or supplement the artist name if it is missing.

  The web interface 39 converts the cue sheet 29 into HTML so that it can be displayed by the web browser 33 (S335). A hyperlink is embedded in each cue Mn in the cue sheet described in HTML. The hyperlink includes the URL of the MP3 file 42 including the song Mn, the station ID of the song Mn, the broadcast start time begin [n], and the broadcast end time end [n].

  The web browser 33 displays the song list on the display based on the cue sheet described in HTML (S336). The song list includes the title, artist name, broadcast start time, etc. of each song. At this time, reproducible songs are displayed in a selectable manner, but songs that cannot be reproduced because they are not recorded are displayed in a nonselectable manner.

  When the user clicks a desired song with a mouse or the like, the web browser 33 selects the desired song in response to this input operation (S337), and issues a query to the web interface 39 to read the song. In response to this query, the web interface 39 extracts the designated song from the MP3 database 34 (S338: song extraction process), and plays the extracted song (S339).

  FIG. 15 is a flowchart showing details of S336 to S339. The web interface 39 generates a song list shown in FIG. 16 in response to a user operation, and the web browser 33 displays this (S1). The song list is, for example, a song list in which songs corresponding to the artist name selected by the user operation are rearranged in alphabetical order or alphabetical order, or a song list in which the song names are rearranged in the order of the number of appearances on the cue sheet in a predetermined period Etc. That is, the order of the songs in the song list is different from the order of the songs in the cue sheet. For example, in the cue sheet shown in FIG. 4 and FIG. 14, the songs A, B, C, D, E and F are arranged in this order, whereas in the song list of FIG. C, song F, song A, song D, song B, and song E are rearranged in this order. The song list includes a broadcast start time and a broadcast end time in addition to the song title. These broadcast start time and broadcast end time are obtained from the cue sheet of FIG. 4 and registered.

  Next, the web interface 39 selects one song from the song list as a song to be played first in response to a user operation (S2). For example, assume that song B is selected in this example.

  The web interface 39 reads the playback range of the selected song from the song list (that is, based on the cue sheet) and specifies it. For example, when song B is selected, broadcast start time 8:12:00 to broadcast end time 8:20:00 (date and time are omitted to simplify the explanation) is reproduced with reference to the song list. Specified as a range. The web interface 39 extracts music data in the specified reproduction range from the MP3 database 34 and outputs it to the web browser 33. The web browser 33 activates the MP3 player 15, and the MP3 player 15 reproduces the music specified based on the MP3 data (S4).

  The web interface 39 determines whether or not a skip instruction is input by a user operation during playback of the selected song (S5). If no skip instruction is input (NO in S5), the web interface 39 determines whether or not the selected song has been played back (that is, whether or not the broadcast data in the playback range specified in S3 has been played back). (S7). If the selected song has not been played back (NO in S7), the process returns to S5. That is, during the reproduction of the selected song, the web interface 39 continues to execute the determination processes of S5 and S7. The skip instruction is input to the web interface 39 when, for example, a skip button provided on a remote controller (not shown) of the PC 13 is pressed. Or a skip instruction | indication is input into the web interface 39 by clicking the skip icon displayed on a display with a mouse | mouth.

  If it is determined in S5 that a skip instruction has been input (YES in S5), the web interface 39 finishes playing the currently selected song and selects the next song in the song list that is currently selected. Then (S6), the process returns to S3. For example, when a skip instruction is input while song B is selected and played, song E next to song B is selected in the song list of FIG. Accordingly, with reference to the song list of FIG. 16, broadcast start time 8:40:00 to broadcast end time 8:50:00 is specified as a playback range (S3), and playback of song E is started (S4).

  On the other hand, if it is determined in S7 that the currently selected song has been reproduced (YES in S7), the web interface 39 ignores the order of the song list and is currently selected in the cue sheet of FIG. The next song (that is, the song actually broadcast after the currently selected song) is selected (S8), and the process returns to S3. For example, when the reproduction of the music B is completed, the music C that is the music after the music B is selected based on the cue sheet of FIG. In this case, in S3, the web interface 39 refers to the cue sheet in FIG. 4 and specifies the broadcast start time 8:20:00 to the broadcast end time 8:35:00 as the playback range (S3). Is started to be reproduced (S4).

  Thereafter, when the reproduction of the music piece C is completed, the music piece D which is the next music piece after the music piece C is selected based on the cue sheet of FIG. In this case, in S3, the web interface 39 refers to the cue sheet in FIG. 4 and specifies the broadcast start time 8:35:00 to the broadcast end time 8:40:00 as the reproduction range (S3), and the song D Is started to be reproduced (S4). Thus, unless a skip instruction is input, songs are continuously played in the order of the cue sheets.

  Even if a song to be played first is selected from the song list by the above processing, the order of the song list is ignored unless the skip instruction is input by the user operation, and the order described in the cue sheet (that is, actually The songs are selected and played continuously in the order of broadcast).

  Accordingly, as shown in FIG. 14, when the playback range of the song E is continuously played back in the order of the song list after the playback range of the song B is played back, the introduction of the song C by the DJ is played after the playback of the song B is finished. Later, the song E is reproduced, and the broadcast data to be reproduced loses continuity. However, in this example, after the playback range of the song B is played, the playback range of the song C is continuously played in the order of the cue sheet. Therefore, after the playback of the song B, the introduction of the song C by the DJ is played back. Later, song C is played back, and the continuity of the broadcast data played back is maintained.

  When the playback range of the song F is continuously played back in the order of the song list after the playback range of the song C is played back, the introduction of the song D by the DJ is played after the playback of the song C, and the first 30 seconds of the song D Is reproduced, music F starts to be reproduced, and the broadcast data to be reproduced is not continuous. However, according to this example, after the reproduction range of the song C is reproduced, the reproduction range of the song D is continuously reproduced in the order of the cue sheet. Therefore, after the reproduction of the song C, the introduction of the song D by the DJ is reproduced. After that, the tune D is reproduced and the continuity of the reproduced broadcast data is maintained.

  When the playback range of the song D is continuously played back in the order of the song list after the playback range of the song A is played, the introduction of the song B by the DJ is played after the playback of the song A, and the 30th second of the song D is played back. The broadcast data to be played is no longer continuous. However, according to this example, after the playback range of the song A is played, the playback range of the song B is continuously played in the order of the cue sheet. After that, the tune B is reproduced and the continuity of the reproduced broadcast data is maintained.

  On the other hand, when a skip instruction is input by a user operation, a song next to the currently selected song in the song list is selected and reproduction is started. Therefore, when the user desires to reproduce the songs in the order of the song list, the user can press the skip button on the remote controller and input a skip instruction to the web interface 39 to execute continuous reproduction in the order of the song list. it can. Note that when a skip instruction is input, the song immediately before the currently selected song in the song list may be selected. For example, when a skip instruction is input when the song B is selected, the song D immediately before the song B may be selected in the song list and playback may be started.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. TV broadcasting may be employed instead of FM radio broadcasting. That is, the content referred to in the present invention is not limited to audio data, and video (image) data and / or audio data may be employed. Further, the present invention may be provided in the form of an air check program for causing a computer to execute the above-described processes of the present invention or a recording medium storing the program.

  The present invention can be suitably employed in an air check device.
