Description

  The present invention relates to a content recording / playback apparatus, and more particularly, to a content recording / playback apparatus that automatically acquires desired content from among a large number of contents 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 radio FM broadcasting, it may be known in advance that a desired song is broadcast during a program, but since the program contains CM and MC (DJ audio), the desired song is in the program. I don't know when it will be broadcast. Therefore, in order to record the desired song, the viewer must continue to listen carefully to the program from the beginning.

  By the way, a broadcasting station uses a cue sheet describing a program progress schedule. The cue sheet details the title of the song that was broadcast, the name of the artist, the broadcasting time, etc., but some broadcast stations provide the cue sheet to viewers via the Internet after the program is broadcast. There are some places. This cue sheet allows viewers to know exactly what songs were broadcast when, but since those songs were already broadcast, there was a desired song in them But it is impossible to record now.

  In order to solve this problem, a recording apparatus disclosed in Patent Document 1 has been proposed. According to this technique, the recording device records a television broadcast program, and at the same time, the index distribution device creates a scene index of the program. The scene index is information indicating the generation time and contents of each scene appearing in the program. After the program ends, this scene index is distributed from the index distribution device to the recording device. The user of the recording apparatus selectively reproduces only a desired scene from the recorded program based on the distributed index. In this case, when the user selects a desired song of a desired artist from the recorded program, the song is cued from the program and can be reproduced.

  However, according to the above technique, when a plurality of the same songs are recorded, each song was broadcast only partway through the song, so the recorded part of the MC and MC could be recorded very long, As a result, there are various songs such as a song having many unnecessary recording parts different from the song body. Therefore, the user needs to select and play the most preferable music (for example, music closest to the original music, music with the best S / N ratio) from among the same music by his / her operation. There is a problem that this operation is extremely complicated.

  Patent Document 2 below describes the following technology. Receive broadcast data, store the received broadcast data, extract content data included in the broadcast data from the stored broadcast data with reference to the playlist, and erase the broadcast data excluding the extracted content data . If the content data overlaps, the remaining content data is erased except for one.

  However, according to the above technique, there is a problem that the most preferable music is automatically deleted and the user cannot select and reproduce it.

JP2002-262224 JP2003-203467

  It is an object of the present invention to record and reproduce content that can automatically select and reproduce the most preferable song (for example, a song whose recorded content is closest to the original song) when a plurality of identical songs are recorded. Is to provide a device.

  A content recording / playback apparatus according to a preferred embodiment of the present invention includes a receiving means for receiving broadcast data including a plurality of contents broadcast from a broadcasting station, and a recording means for recording the broadcast data received by the receiving means on a storage medium. And when a plurality of the same contents are recorded on the storage medium, recommended content determination means for determining a recommended content based on a predetermined condition from the plurality of the same contents, and a plurality of the contents recorded on the storage medium Display means for displaying content information of the content, recommended content notification means for notifying the user of the recommended content determined by the recommended content determination means, specification means for specifying desired content in response to a user operation, and the specification Playback means for playing back the content designated by the means.

  The recommended content is determined from the plurality of identical contents by the recommended content determination means, and the user is notified that the recommended content is the recommended content by the recommended content notification means. By selecting, it is possible to reproduce the most preferable content (for example, recorded in the form closest to the original content) from among a plurality of the same content. This eliminates the need for the user to play back a plurality of identical contents one by one to find the best contents, thereby simplifying the selection operation.

  In a preferred embodiment, the recommended content determination means determines the recommended content based on the recording time of the content body and / or the recording time of data other than the content recorded before and after the content body.

  Based on the recording time of the content body and the recording time of data other than the content recorded before and after the content body (for example, MC, CM, etc.), the recommended song is determined (for example, the recording time of the content body is long). By determining the content having a short recording time of data other than the content and the content main body as the recommended content), the content having the recording content closest to the original content can be determined as the recommended content.

  In a preferred embodiment, the content recording / playback apparatus refers to a connection unit that connects to a cue sheet server, an acquisition unit that acquires a cue sheet from the cue sheet server, and a recording medium that refers to the cue sheet. Extraction means for extracting content designated by the designation means from the broadcast data. The recommended content determination unit determines a recommended content for the content included in the cue sheet acquired by the acquisition unit.

  When the acquisition unit newly acquires a cue sheet, the recommended content is determined from among a plurality of identical contents for the content included in the cue sheet, so that the most preferable content can always be selected as the recommended content.

  In a preferred embodiment, the recommended content notification means selects only the recommended content from a plurality of identical contents and causes the display means to display the selected content.

  In a preferred embodiment, the recommended content notification unit causes the display unit to display all of the plurality of identical contents, and further displays on the display unit that the recommended content is a recommended content.

  The user selects the recommended content announced from the plurality of the same content, thereby reproducing the most preferable content (for example, recorded in the form close to the original content) from the plurality of the same content. Can do.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to these embodiments. As shown in FIG. 1, a content recording / playback 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 a content recording / playback apparatus.

  The PC 13 is a general-purpose device, and includes a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), a hard disk drive (HDD), an optical disk drive, a display, a keyboard, a mouse, and the like. A content recording / playback program, which will be described in detail 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.

  The cue sheet server 12 converts the cue sheet acquired from the broadcasting station server 16 into a predetermined common format as shown in FIG. The cue sheet 26 includes a field 261 that describes a station ID (identifier) assigned to each broadcasting station, and a plurality of records 262 corresponding to a plurality of songs broadcast from the broadcasting station. Each record 262 describes the broadcast start time (including time and date) of the corresponding song, broadcast end time, and metadata (content information). The metadata includes a song name, an artist name, and the like. FIG. 3 shows an example of the cue sheet 26.

[FM tuner and PC (content recording / playback device)]
As shown in FIG. 4, 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, and a content recording / playback program (38-41), which will be described in detail later. 34, a recording status management database 35, an index database 36, a cue sheet database 37, and a recommended song database 47 are constructed. The content recording / playback program includes an index generation module 38, a web interface 39, a cue sheet 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.

  As shown in FIG. 5, 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. 6 (S311) and stores it in the recording situation management database 35 (S312).

  As shown in FIG. 6, the recording status management table 43 has 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. 7 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. 7, the 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. 8, 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. 9 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 FIG. 9 shows the elapsed time (seconds) from the beginning of the MP3 file 42, 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.

  As shown in FIG. 10, the cue sheet acquisition module 40 in the PC 13 requests the cue sheet server 12 to transmit a desired cue sheet 29 (S331). The cue sheet server 12 accepts this request (S111), reads the desired cue sheet 29 from the cue sheet database 28, and transmits it to the PC 13 (S112).

  The cue sheet acquisition module 40 receives the cue sheet 29 transmitted from the cue sheet server 12 (S332) and stores it in the cue sheet database 37 (S333). FIG. 11 shows an example of the acquired cue sheet 29.

  Next, the web interface 39 edits the content of the recommended song database 47 based on the newly acquired cue sheet (S334).

  The recommended song database 47 stores a recommended song table 48 shown in FIG. The recommended song table 48 is a table for determining a recommended song from a plurality of the same songs and notifying the user of the recommended songs when a plurality of the same songs are recorded in the MP3 database 34. The recommended song is, for example, a song recorded in a form close to the original song or a song having the best S / N ratio. Close to the original song means, for example, that the recording time of the song body is close to the recording time of the original song, or a part other than the song body before and after the song body (for example, CM or MC (master of ceremonies): Recording time) (which is a sound of DJ).

  As shown in FIG. 12, the recommended song table 48 includes a recording time (seconds) of each evaluation item for the current recommended song and the same recommended song (hereinafter referred to as an additional song) included in the newly acquired cue sheet. And a score field and a total score field. Furthermore, the recommended song table 48 includes fields of song information (song title, artist name, broadcast start time, broadcast end time, station ID) of recommended songs and additional songs. If the total score of the current recommended song is compared with the total score of the additional song and the total score of the additional song is less than the total score of the current recommended song, the additional song is determined as a new recommended song, and the additional song Each value in the field is registered in the recommended song field. Otherwise, the current recommended song is maintained as the recommended song.

  The evaluation items include, for example, the recording time (length) of the MC before the start of the song, the recording time of the MC after the end of the song, and / or the recording time of the song body. As shown in FIG. 13, T1 corresponds to the MC recording time before the song starts, T2 corresponds to the recording time of the song body, and T3 corresponds to the MC recording time after the song ends. The evaluation items include a time when the song and MC overlap at the start of the song (referred to as cross) and a time when the song and MC overlap at the end of the song (cross) as necessary. As shown in FIG. 13, T4 corresponds to the time when the song and MC overlap at the start of the song, and T5 corresponds to the time when the song and MC overlap at the end of the song. In addition, as an evaluation item, an S / N ratio of a song, a station ID (broadcast station), a broadcast start time, or the like may be employed.

  Each evaluation item can be set with a weighted score. The weighting may be a predetermined default value or may be arbitrarily changed by the user. For example, the recording time of the MC before the start of the song is “× 3”, the recording time of the MC after the end of the song is “× 2”, the recording time of the song body is “× −1”, and the like.

  The method for calculating the total number of recommended songs and additional songs is as follows. First, the MP3 file is read, the recording time of each evaluation item is detected, and the time is registered in the recording time field of each item. Next, for each item, a value obtained by multiplying the recording time by a weighting coefficient is registered as a score in the score field. However, with respect to the recording time of the song body, the score is 0 based on the recording time of the recommended song, and the score of the additional song is “recording time of the song body of the additional song−recording time of the song body of the recommended song” × (− Calculated in 1). The total score is calculated by adding the scores of each item and registered in the total score field.

  The recommended song table update process will be described with reference to FIGS. 14 and 15. FIG. As shown in FIG. 14, the web interface 39 determines whether or not the music (added music) included in the newly acquired cue sheet actually exists in the MP3 database as an MP3 file based on the cue sheet and the index file. Judgment is made (S351). If the MP3 file of the additional music does not exist (S351: NO), the additional music is not recorded, so the process is terminated without registering as a recommended music. Thereby, it is possible to prevent a user from notifying a song that does not actually exist as an MP3 file as a recommended song.

  When the MP3 file of the additional music exists (S351: YES), the web interface 39 calculates the score and the total score of each evaluation item of the additional music (S352).

  FIG. 15 is a diagram showing details of S352. First, the web interface 39 registers the song information of the added song in the song information field of the added song in the recommended song table 48 (S361). Next, the web interface 39 refers to the cue sheet, the recording status management database, and the index file, reads the portion where the additional music is recorded from the MP3 file, and determines the following contents.

  The web interface 39 detects the recording time of the MC before the start of the song and the recording time of the MC after the end of the song for the additional song, and registers these information in the corresponding fields of the recommended song table 48 (S362). The process for detecting the recording time of the MC employs, for example, a method for determining whether the broadcast content is voice or music described in JP-A-8-22295, or a known music recognition technique such as MusicID. Can be implemented.

  The web interface 39 calculates the recording time of the song body for the added song and registers it in the corresponding field of the recommended song table 48 (S363). This process may be detected by the above method, but can be easily calculated by subtracting the MC recording time T1 before the music start and the MC recording time T3 after the music end from the entire recording time, for example.

  Next, the web interface 39 detects a recording time when the song and the MC overlap at the start of the song and a recording time when the song and the MC overlap at the end of the song as necessary, and the recommended song table 48. Is registered in the corresponding field (S364).

  Subsequently, the web interface 39 calculates the score by multiplying the recording time of each evaluation item by the weighting coefficient for the additional music, and registers it in the corresponding field. Further, the score of each evaluation item is added to calculate the total score, and is registered in the total score field (S365).

  Returning to FIG. 14, it is determined whether or not the same music as the additional music has been broadcast within a certain past period and recorded as an MP3 file in the MP3 database (S 353). This process is executed by determining whether or not a combination of the song name and artist name of the additional song exists in the recommended song table 48. When the additional music is broadcast for the first time, the same music of the additional music is not registered in the recommended music table 48, and therefore it is determined NO in S353. Further, as will be described later, since the MP3 file is deleted by the sweeper module after a lapse of a certain period after recording, the tune that has passed for a certain period is erased from the recommended tune table 48, and NO is determined in S353.

  If the same song does not exist in the recommended song table 48 (S353: NO), it is determined that the additional song has been broadcast for the first time and recorded as an MP3 file, or was previously recorded as an MP3 file but has been deleted. The interface 39 registers the music information of the additional music in the recommended music table 48 as a recommended music (S355), and registers the score and total score of each evaluation item of the music.

  When the same music exists in the recommended music table 48 (S353: YES), the web interface 39 compares the total score of the additional music with the total music score of the recommended music, and the total score of the additional music is the total score of the recommended music. It is determined whether it is less than (S354). If the total score of the additional songs is less than the total score of the recommended songs (S354: YES), since the additional songs are determined to be closer to the original songs, the web interface 39 sets the additional songs as new recommended songs. Then, each information of the additional song field of the recommended song table 48 is registered in the recommended song field, and the additional song field is cleared (S355).

  On the other hand, if the total score of the additional songs is equal to or greater than the total score of the recommended songs (S354: NO), the current recommended song is determined to be closer to the original song, so the web interface 39 displays the current recommended song. Is determined as the recommended song as it is, and each information in the field of the additional song is cleared.

  The process of updating the recommended song table described above is executed for all songs included in the newly acquired cue sheet. As a result, every time a cue sheet is acquired, a song closest to the original song can be registered as a recommended song.

  Returning to FIG. 10, as shown in FIG. 16, the web interface 39 adds recommended song information indicating a recommended song to the cue sheet (S335). Specifically, the same song information as the song information (song name, artist name, broadcast start time, broadcast end time, station ID) included in the cue sheet is registered in the recommended song field of the recommended song table 48. If it is registered, the recommended music information is added to the cue sheet for the music (for example, music AAA (21: 01: 0 to 21:16:59), DDD). On the other hand, if the song is not registered, the song is not a recommended song, so the recommended song information is not added to the cue sheet (for example, song AAA (22:11:00 to 22:24:59), BBB, CCC).

  Next, the web interface 39 converts the cue sheet 29 into HTML so that it can be displayed by the web browser 33 (S336). A hyperlink is embedded for each song in the cue sheet described in HTML. In addition to the URL of the MP3 file 42 containing the song, the hyperlink includes the station ID, broadcast start time, broadcast end time, and recommended song information of the song.

  The web browser 33 displays the song list on the display based on the cue sheet described in HTML (S337). The song list includes the title, artist name, broadcast start time, and broadcast end time of each song. At this time, the recorded and reproducible music is displayed in a selectable manner, but the music that cannot be reproduced because it is not recorded is displayed in a nonselectable manner.

  Further, the user is notified that the music having the recommended music information is a recommended music. There are typically the following two methods for notifying recommended songs. First, as shown in FIG. 17, after all the same songs are displayed in the song list, the recommended song is further indicated as a recommended song, or the recommended song is different from other songs (for example, This is a method of notifying the user that the recommended song is displayed in different colors or sizes. In FIG. 17, two songs AAA are displayed, but only one of them is provided with recommended song information. The second is a method of notifying the user of recommended songs by displaying only recommended songs in the song list and not displaying other songs. In this case, the music AAA of 22:11:00 to 22:24:59 is not displayed. Both methods can be executed by determining whether or not recommended song information is added to the cue sheet and identifying whether or not the recommended song is a recommended song.

  Subsequently, when the user clicks a desired song with a mouse or the like, the web browser 33 designates the desired song in response to this input operation (S338), 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 the designated song from the MP3 database 34 (S339). Details of the extraction method are as follows.

  The web interface 39 refers to the recording status management database 35 and identifies the file name of the MP3 file 42 based on the station ID, broadcast start time, and broadcast end time of the designated song. The web interface 39 refers to the index file 44 corresponding to the specified file name, and extracts MP3 data from the broadcast start time to the broadcast end time in the MP3 file 42 (see FIG. 8). Then, the web interface 39 returns the extracted MP3 data to the web browser 33.

  In addition to extraction in units of music as described above, the user can specify the start time and end time manually to perform extraction in units of programs, or specify only the start time to perform endless playback. It is also possible to do.

  The web browser 33 activates the MP3 player 15, and the MP3 player 15 reproduces the music designated based on the MP3 data (S340).

  If the above operation is continued, a huge amount of data is accumulated in a storage medium such as a hard disk. Therefore, the sweeper module 41 in the PC 13 periodically (eg, every week) deletes the MP3 file 42, the recording status management table 43, the index file 44, and the cue sheet 29 that have passed a predetermined period (eg, one month). . The erasing cycle and the erasing target are appropriately determined according to the capacity of the storage medium.

  As described above, according to the embodiment of the present invention, the PC 13 stores all broadcast data received by the FM tuner 14 in the MP3 database 34, and then refers to the cue sheet 29 acquired from the cue sheet server 12. Since a desired song is extracted from the stored broadcast data, the desired song can be automatically acquired from a large number of songs broadcast from the broadcasting station.

  Further, the MP3 file 42 is divided into a plurality of sections 45 at predetermined time intervals, and an index file 44 including the offset of each section 45 is generated. Therefore, the PC 13 refers to the index file 44 to determine a desired song. Extraction can be made reliably in time units.

  In addition, every time a cue sheet is acquired, a recommended song is determined from a plurality of the same songs, and when the song list is displayed, the user is notified that the recommended song is a recommended song. , Can play the most preferable song. Therefore, it is not necessary for the user to manually select the most preferable song from among a plurality of the same songs.

  In the above embodiment, the software MP3 player 15 is installed in the PC 13, but instead of or together with this, a hardware MP3 player device (for example, home audio, portable player, etc.) may be used. . In this case, the MP3 file may be transmitted from the PC 13 to the MP3 player device via wired or wireless communication, but may be copied via a memory card such as a flash memory or an optical disk such as a CD or DVD. . Needless to say, an audio compression method other than MP3, for example, AAC (Advanced Audio Cording) may be used. However, the present invention can be applied not only to music content 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, both the broadcast start time and the broadcast end time are used. However, either one (typically the broadcast start time) may be used, in other words, even the broadcast time of the content is specified. If possible.

  In the above-described embodiment, the PC 13 simply displays the cue sheet. However, only a desired artist's music is extracted from a plurality of cue sheets acquired within a predetermined period, and a folder is displayed for each artist. It is also possible to create an MP3 file and store it separately.

  In the above-described embodiment, the web browser 33 and the MP3 player 15 are provided in the local PC 13, but instead, in another PC on the network, a dedicated device, a mobile phone, or a PDA (Personal Digital Assistance) May be provided. In this case, if the web interface 39 can be accessed from within a home via a LAN (Local Area Network) or from outside the home via the Internet, the music list can be displayed, the music can be designated and played back.

  In the above-described embodiment, the FM tuner 14 and the PC 13 constitute a content recording / playback device. However, an integrated dedicated device that receives FM broadcasts and records them on a hard disk, or a mobile phone having a memory instead of the hard disk May constitute a content recording / reproducing apparatus.

  Also, for a file in which the recorded MP3 file is manually divided by a user without using a cue sheet, a recommended song can be determined and the recommended song can be notified to the user. In addition to cueing a song by referring to an index file from one MP3 file, the MP3 file may be automatically divided for each song by referring to a cue sheet. The method for determining the recommended song is not limited to the above embodiment.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. The present invention may be provided in the form of a computer program for operating the above-described image reproducing apparatus or a storage medium recording the computer program.

  The present invention can be suitably applied to a content recording / reproducing apparatus that records a broadcast and reproduces it later.
