Further, one or a plurality of contents included in the selected program are specified based upon a queue sheet and displayed in a content list. When one content is selected out of the specified contents, the broadcast time of the specified content is specified based upon the queue sheet and broadcast data of the specified broadcast time is extracted.

Description

  The present invention relates to a data extraction device and a program thereof.

  Terminal devices such as HDD recorders and PCs receive broadcast data including contents such as music data and video data broadcast on radio or television, record the data as a broadcast data file on a storage medium such as HDD, and record the recorded broadcast data You can play the file later. However, the user 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, Japanese Patent Application Laid-Open Publication No. 2004-228620 proposes a terminal device that extracts and plays back a desired song using a cue sheet. This terminal device acquires a cue sheet describing the broadcast start time, song name, etc. of the broadcasted song from the server and stores it. The terminal device receives the FM broadcast and records the received broadcast data on the HDD. Then, referring to the cue sheet, a desired song is extracted from the recorded broadcast data and reproduced.

  The terminal device generates a song list in which the names of the songs of the selected artist are sorted in alphabetical order and alphabetical order, a song list in which the release dates are included in a predetermined period, sorted in order from the oldest release date, etc. And display on the display. When one song is selected from the song list by a user operation, the selected song is extracted and played. When the selected song has been played, the next song after the selected song in the song list is automatically selected, and the selected song is extracted and played. That is, songs are successively extracted from the selected songs in the order listed in the song list and reproduced.

  Further, the terminal device acquires a program guide describing the broadcast start time, program name, etc. of the broadcasted program from the server and stores it. The terminal device generates a program list from the program guide and displays it on the display unit. When one program is selected from the program list by the user operation, the terminal device refers to the program guide and extracts and plays back the selected program from the recorded broadcast data.

  As described above, when a desired song or program is selected from the song list or program list, the terminal device can extract and play the selected song or program from the broadcast data. Here, when a song is selected from the song list and the song is extracted and played, if the user wants to play the entire program including the song, the program list is displayed instead of the song list, and the program list is displayed. It is necessary to search for and select a program including the song from. Therefore, it is extremely difficult to find a program including the song, and it takes a lot of time. Similarly, when a program is selected from the program list and the program is extracted and played back, if the user wants to select and play a song included in the program, the song list is replaced with the program list. It is necessary to search and select a song included in the program from the song list. Therefore, it is very difficult to find a song included in the program, and it takes a very long time.

  The program includes one or more corners. When a program is selected from the program list and the program is extracted and played back, one of the one or more corners included in the program is selected. When it is desired to reproduce, it is necessary to select an arbitrary reproduction position by a user operation or to input a fast forward instruction. Therefore, it is very difficult to find a corner included in the program, and it takes a lot of time.

  The receiving unit 13 receives broadcast data having a plurality of programs including one or more contents broadcast from a broadcast station (not shown). Content is a general term for music data, video data, and / or image data, and is music data in this example. The broadcast is a TV broadcast or a radio broadcast, and any broadcast such as a digital broadcast, an analog broadcast, a satellite broadcast, or an Internet broadcast can be adopted. In this example, FM broadcasting having a plurality of programs including one or a plurality of song data will be described as an example.

  The HDD 14 records the broadcast data received by the receiving unit 13. When the broadcast data received by the receiving unit 13 is in an analog format, the broadcast data is converted from analog to digital and recorded in the HDD 14. Although not particularly limited, the broadcast data is divided into broadcast data files (for example, MP3 files) every predetermined time (for example, 6 hours) and recorded on the HDD 14.

  The HDD 14 stores the broadcast data file list shown in FIG. The broadcast data file list includes the broadcast start time (that is, the recording start time on the HDD 14), the broadcast end time (that is, the recording end time on the HDD 14), and the file name for all the broadcast data files recorded on the HDD 14. It is a list to be managed. New information is registered in the broadcast data file list by the control unit 11 every time a broadcast data file for every predetermined time is recorded in the HDD 14.

  The communication unit 15 connects to the server 100 via an arbitrary telecommunication line such as the Internet, acquires a program guide from the server 100, and stores it in the memory 12. FIG. 3 is a diagram illustrating an example of a program guide. The program guide includes a broadcast start time, a broadcast end time, and a program name (title). Broadcast start time and broadcast end time are collectively referred to as broadcast time, and program name and the like are collectively referred to as specific information. Other specific information includes the name of a person who appears in the program, an outline of the program, and the like. FIG. 3 shows that a program whose program name is program 1 was broadcast from 8:00 to 9:00 on July 8, 2010. The program guide may be received by the receiving unit 13 together with the broadcast data.

  The communication unit 15 connects to the server 100 via an arbitrary telecommunication line such as the Internet, acquires a cue sheet from the server 100, and stores it in the memory 12. FIG. 4 is a diagram illustrating an example of a cue sheet. The cue sheet includes a broadcast start time, a broadcast end time, a song title (title), and an artist name. Broadcast start time and broadcast end time are collectively referred to as broadcast time, and song titles, artist names, etc. are collectively referred to as specific information. The specific information includes a genre name, an album name, a release date, and the like. FIG. 4 shows that a song with an artist name of artist A and a song name of song A was broadcast from 8:02 to 8:12 on July 8, 2010. The cue sheet may be received by the receiving unit 13 together with the broadcast data.

  The control unit 11 generates a song list that is a list of songs recorded in the HDD 14 based on the cue sheet. FIG. 5 is a diagram showing an example of a song list. The song list includes a broadcast start time, a broadcast end time, a song name (title), and an artist name. The song list may include a release date. The song list includes a song list in which the names of the songs of the selected artist are sorted in alphabetical order and alphabetical order, a song list in which release dates are included in a given period, sorted in order from the oldest release date, There is a song list in which the song names are sorted in the order of the number of appearances on the cue sheet during the period.

  The control unit 11 displays a song list screen including a song list on a display unit (not shown). FIG. 6 is a diagram illustrating an example of a song list screen. A desired song can be selected by moving the cursor displayed on the song list screen by a user operation. When the song is selected, the control unit 11 specifies the broadcast start time and the broadcast end time of the selected song based on the cue sheet. The control unit 11 extracts broadcast data from the specified broadcast start time to the broadcast end time from the broadcast data file recorded in the HDD 14 and causes the reproduction unit 16 to reproduce the broadcast data.

  For example, when the artist C and the song C are selected by the user operation, the control unit 11 refers to the cue sheet in FIG. 4 (or the song list in FIG. It is determined that the broadcast data is from 8:20 to 8:35 on July 8, 2012. The control unit 11 then transmits a broadcast data file including broadcast data from 8:20 to 8:35 on July 8, 2010 (ie, July 8, 2010) from the broadcast data file list of FIG. The broadcast data file 1) from 6:00 to 12:00 on the day is specified. The control unit 11 extracts data corresponding to 8:20 to 8:35 from the specified broadcast data file and causes the reproduction unit 16 to reproduce the data.

  Moreover, the control part 11 specifies the program containing the selected music from a program schedule, when a music is selected on a music list screen. Specifically, the control unit 11 specifies the broadcast start time and broadcast end time of the selected song based on the cue sheet. The control unit 11 specifies a program including the specified broadcast start time to the broadcast end time from the program guide. The control unit 11 acquires the broadcast start time, broadcast end time, and / or program name of the identified program from the program table and displays them on the right side of the song list screen as shown in FIG.

  For example, when the artist C and the song C are selected by the user operation, the control unit 11 refers to the cue sheet in FIG. 4 (or the song list in FIG. 5), and the control unit 11 determines that the selected broadcast data is 2010. It is determined that the broadcast data is from 8:20 to 8:35 on July 8, 2012. Then, the control unit 11 selects a program including 8:20 to 8:35 on July 8, 2010 from the program table (that is, program 1, July 8, 2010, 8:00 to 9). 00: 00) is specified, and the program information of the specified program is displayed on the song list screen.

  In addition, a “program playback” button is displayed on the right side of the song list screen. When the “program playback” button is selected (pressed) by a user operation, the control unit 11 extracts a specified program and causes the playback unit 16 to play it instead of extracting and playing a song. That is, the control unit 11 specifies the broadcast start time and the broadcast end time of the specified program based on the program guide. The control unit 14 extracts broadcast data from the specified broadcast start time to the broadcast end time from the broadcast data file recorded in the HDD 14 and causes the reproduction unit 16 to reproduce the broadcast data.

  For example, when the program 1 is displayed on the song list screen, the control unit 11 determines that the broadcast data of the program to be extracted is 8:00 on July 8, 2010 based on the program information specified from the program guide. It is determined that the broadcast data is from minutes to 9:00. Then, the control unit 11 transmits a broadcast data file including broadcast data from 8:00 to 9:00 on July 8, 2010 (ie, July 8, 2010) from the broadcast data file list of FIG. (Broadcast data file of 6:00 to 12:00 of the day) is specified. The control unit 11 extracts data corresponding to 8:00 to 9:00 from the specified broadcast data file, and causes the reproduction unit 16 to reproduce the data.

  Thereby, when a song is selected from the song list screen, broadcast data of a program including the selected song can be easily selected and extracted. In the music list screen of FIG. 6, only the “program playback” button may be displayed and the program information may not be displayed. Further, the program specific information including the selected song and the “program playback” button may be displayed on a screen different from the song list screen.

  Next, the operation of the present invention will be described. As illustrated in FIG. 7, the control unit 11 causes the reception unit 13 to receive broadcast data broadcast by the broadcast station 10. The control unit 11 encodes the received broadcast data and generates a broadcast data file (S1). The control unit 11 causes the HDD 14 to record a broadcast data file every predetermined time (S2). At this time, the control unit 2 registers the broadcast start time, the broadcast end time, and the file name in the broadcast data file list of FIG. That is, the time when the broadcast data file starts to be recorded on the HDD 5 is registered as the broadcast start time, and the time when the broadcast data file is recorded on the HDD 5 is registered as the broadcast end time.

  The control unit 11 acquires the program guide and the cue sheet from the server 100 and stores them in the memory 12 (S3). The control unit 11 generates a music list based on the cue sheet and stores it in the memory 12 (S4). The song list is generated by extracting the broadcast start time, broadcast end time, song name, and artist name from the cue sheet and listing them. The song list is generated in HTML format. The music list may be newly generated every time the cue sheet is updated. The control unit 11 generates a music list screen as shown in FIG. 6 from the music list and displays it on a display unit (not shown).

  As shown in FIG. 8, the control unit 11 determines whether or not a song is selected by a user operation from the song list screen (S11). When selected (YES in S11). The control unit 11 extracts the selected song from the broadcast data file (S12) and reproduces it (S13). Specifically, the control unit 11 specifies the broadcast start time and the broadcast end time of the selected song from the cue sheet (or song list), and includes broadcast data from the specified broadcast start time to the broadcast end time. A broadcast data file is specified from the broadcast data file list. The control unit 11 extracts broadcast data from the specified broadcast start time to the broadcast end time from the specified broadcast data file.

  Subsequently, the control unit 11 acquires the broadcast time and specific information of the program including the song selected on the song list screen from the program guide, and displays it on the song list screen (S14). Specifically, the control unit 11 specifies the broadcast start time and the broadcast end time of the selected song from the cue sheet (or song list), and shows a program including the specified broadcast start time to the broadcast end time. Specify from the table. The control unit 11 acquires the broadcast start time, broadcast end time, and program name of the specified program from the program guide and displays them on the song list screen. The broadcast start time and broadcast end time acquired here may be stored in the memory 12 in order to extract and reproduce the broadcast data of the program later.

  When the selected song is being played back, the control unit 11 determines whether or not the selected song has been played back to the end (S15). That is, it is determined whether or not broadcast data has been extracted and reproduced until the specified broadcast end time. When the reproduction to the end is completed (YES in S15), the control unit 11 automatically selects the next song in the song list (S16), and returns to S12. Therefore, unless the “program playback” button displayed on the song list screen is selected, songs are extracted from the broadcast data file and played in the order listed in the song list. Also, the broadcast start time, broadcast end time, and program name of the program displayed on the song list screen are similarly changed according to the song.

  The control unit 11 determines whether or not an instruction to play a program instead of a song is input by a user operation (S17). That is, it is determined whether or not the “program playback” button on the song list screen has been selected. When the “program playback” button is selected (YES in S17), the control unit 11 extracts broadcast data of a program including the selected song and plays it instead of extracting and playing the selected song (step S17). S18, S19).

  Specifically, the control unit 11 specifies the broadcast start time and broadcast end time of the program displayed on the song list screen based on the program table. In this case, since the broadcast start time and broadcast end time of the program are already acquired from the program table and stored in the memory 12 in S14, these may be used. The control unit 11 specifies a broadcast data file including broadcast data from the specified broadcast start time to the broadcast end time from the broadcast data file list. The control unit 11 extracts broadcast data from the specified broadcast start time to the broadcast end time from the specified broadcast data file.

  When a song is selected from the song list by the above processing, a program including the selected song is specified from the program guide and displayed on the song list screen. Therefore, it is not necessary to select a program including the selected song from the program list by a user operation, and the work can be simplified. If another song is selected from the song list screen by a user operation while the program is being played, YES is determined in S11, and the program is returned to playing the selected song. Can do.
