JP 2010-119140 A

The number of broadcast programs that can be recorded and stored is expected to continue to increase.
The more broadcast programs (recorded programs) that have been recorded and stored, the more difficult it is to find a desired recorded program to be played back from the stored recorded programs, and to find a desired scene from the recorded programs. Things get harder.

  In one aspect of the present invention, it is desirable to be able to easily and efficiently reproduce a desired scene in a stored recorded program.

  A program playback apparatus according to one aspect of the present invention receives a broadcast signal of a broadcast program of at least one channel, and stores broadcast program data based on the broadcast signal received by the receiver. A recording section for recording a broadcast program, and a recording having the specific scene for extracting and playing back at least one specific scene from at least one of the recorded programs that are broadcast programs recorded by the recording section Recording by the recording unit based on the extracted reproduction information acquired by the information acquisition unit, and the extracted reproduction information acquired by the information acquisition unit including information indicating the channel of the program and the time zone of the specific scene in the recorded program The specific scene data is extracted from the recorded program data, and the specific scene is reproduced based on the extracted data. It includes an exit playback unit.

  In the present invention, “reproduction” does not mean only outputting both video and audio so as to be viewable. In the present invention, “playback” refers to one of the entire recorded program data to be played back, such as a playback method that outputs video but not audio, or a playback method that outputs audio but not video. Including outputting only a part.

  According to the program playback apparatus configured as described above, the user can easily and efficiently play back a desired scene from the stored recorded programs based on the extracted playback information.

  The number of specific scenes may be one or more. Also, the number of specific scenes that can be extracted from one recorded program may be one or more. The reproduction of a specific scene may be performed by extracting the data of the specific scene directly from the recorded program data each time it is reproduced, or storing the data of the specific scene once extracted and reproduced. When the specific scene is reproduced again, the stored data of the specific scene may be reproduced without extracting from the recorded program data.

  In the program reproducing device having the above configuration, a scene specifying unit that specifies at least one specific scene from a recorded program recorded by the recording unit according to a predetermined scene specifying method, and a specific scene specified by the scene specifying unit And an information generation unit for generating extracted reproduction information for reproducing.

According to the program reproducing apparatus configured as described above, the user can generate the extracted reproduction information according to the scene specifying method.
Accordingly, the user can easily and efficiently reproduce a desired scene using the extracted reproduction information generated by the user. Further, for example, if the generated extracted reproduction information can be shared by a plurality of users, for example, by uploading it to a server, the extracted reproduction information generated by each of the plurality of users can be shared. .

  The program playback device having the above configuration may further include a moving image data generation unit. The moving image data generation unit extracts specific scene data from the recorded program data recorded by the recording unit based on the extracted reproduction information acquired by the information acquisition unit, and based on the extracted specific scene data To generate moving image data of a specific scene. Then, the extraction / reproduction unit may perform reproduction of the specific scene based on the extracted reproduction information acquired by the information acquisition unit by reproducing the moving image data generated by the moving image data generation unit.

  According to the program reproducing apparatus configured as described above, a specific scene corresponding to desired extracted reproduction information can be left as moving image data. For this reason, even if it becomes impossible to obtain the desired extracted playback information, or even if the original recorded program data containing the specific scene indicated by the desired extracted playback information is erased, the video data remains. As long as it is, a specific scene corresponding to the desired extracted reproduction information can be reproduced easily and efficiently.

Further, direct data communication with the server 7 can be performed by wireless communication via the wireless communication unit 25.

  The storage unit 26 records the broadcast program indicated by the broadcast data by storing the broadcast data input from the control unit 30. That is, the storage unit 26 has a function of recording a broadcast program. The storage unit 26 according to the present embodiment has a storage capacity sufficient to record all programs for a certain period (for example, 4 weeks) for broadcast data of all channels (for example, 10 channels) that can be received by the broadcast receiving unit 21. Have

  The reproduction unit 27 receives broadcast program data (broadcast data) from the control unit 30 or recorded program data (recorded data) recorded in the storage unit 26, and reproduces the program represented by the input data. Specifically, the video of the program to be played is displayed on a display screen (for example, a liquid crystal display), and the sound (sound, music, etc.) of the program to be played is output from a speaker. Further, the reproduction unit 27 may display various images (for example, various buttons) other than the program input from the control unit 30 on the display screen.

  Note that the recorded data means data of a broadcast program (that is, a recorded program) stored (that is, recorded) by the storage unit 26 among the broadcast data received and demodulated by the broadcast receiving unit 21.

  The TV connection unit 28 is an interface unit for outputting program data to be played back to an external playback device. By connecting various playback devices having a moving image playback function to the television connection unit 28, the program to be played can be played back by the connected playback device.

  The control unit 30 includes a control unit 31, a memory 32, and the like. In the present embodiment, the control unit 31 is configured mainly with a microprocessor unit (so-called CPU). In the control unit 30, various functions are mainly realized by the control unit 31 executing various applications stored in the memory 32. Note that the control unit 31 can also realize various functions based on various applications stored in a storage device other than the memory 32 (for example, the storage unit 26).

(2) Functions of Control Unit The functions realized by the control unit 30 include at least the above-described live playback function, recording function, and recorded program playback function.

  Specifically, the recording function is a function of recording a broadcast program of the maximum number of channels (for example, 10 channels) that can be received by the broadcast receiving unit 21 in the storage unit 26 in parallel at all times. As described above, the recorded program is held for a certain period (for example, 4 weeks), but after a certain time has elapsed, the recorded program is deleted or the amount of data is reduced according to the recorded program deletion process described later (see FIG. 12). . However, it is also possible to continue to store a specific recorded program as it is (that is, remove it from the target of deletion or data reduction) according to user settings.

  The storage unit 26 associates EPG information (for example, channel, broadcast date, broadcast start time, broadcast end time, program name, program content, performer name, genre, etc.) of each recorded program for each recorded program. And memorized. The EPG information is included in the broadcast data and transmitted from the broadcast station, and can be acquired periodically.

  The recorded program reproduction function mainly includes a basic reproduction function for reproducing a recorded program selected by the user from among the recorded programs stored in the storage unit 26, and an extraction reproduction function for reproducing according to the extracted reproduction information. And are included. Among these, one of the most characteristic functions of the broadcast program recording / reproducing apparatus 1 of the present embodiment is an extraction / playback function. Therefore, the extraction / playback function will be described in more detail.

(2-1) Extraction / Playback Function The extraction / playback function is a function for extracting at least one desired scene from a recorded program and sequentially playing the extracted scenes. The extracted reproduction information determines which scene of which recorded program is reproduced in what order. The extracted reproduction information can be created by the user himself / herself, but the extracted reproduction information created by another user and uploaded to the server 7 can be downloaded from the server 7 and used.

  For example, as shown in FIG. 3, it is assumed that all broadcast programs for at least two days from January 15 (Thursday) to 16 (Friday) in each channel are recorded. That is, in FIG. 3, a list of recorded programs that are recorded is displayed in a program table format. The recorded program list of FIG. 3 can be displayed on the display screen of the playback unit 27, and the user can select and play a desired recorded program from among them. In the recorded program list, in addition to the program name of the recorded program, although not shown, a part or all of the corresponding EPG information is displayed for each recorded program.

  In the example of FIG. 3, the program broadcast from 19:00 on the 15th on ch1 is “Professional baseball broadcast” (match between the Nagoya team and the Tokyo team). Also, the program “Pro Baseball Bulletin” broadcast from 20:54 on the same day at ch3, the program “9 o'clock news” broadcast from 21:00 on the same day on ch2, and the program “day of the day” broadcast from 23:00 on ch3 on the same day. "Event", the program "Sports News" broadcast from 23:40 on the same day in ch1, and the program "Sports & Entertainment" broadcast from 7:30 on ch. Contains news and topics about. All these programs are recorded. In this example, the explanation will be made on the assumption that the Nagoya team has won a good game in a game on the 15th, for example.

  In this example, if you like professional baseball and you are a fan of the Nagoya team, you can easily expect to see as much news as possible that tells you that the Nagoya team has won. In that case, a generally considered playback method is to predict a program that seems to convey the victory of the Nagoya team from the recorded program list, play the recorded program, and play the desired scene ( In this example, a playback method of searching for a news report regarding a match of the Nagoya team is conceivable. However, such a reproduction method is very troublesome and time consuming for the user. Of course, it would be convenient if you could easily find the recorded program reporting the Nagoya team's game, but it would be more convenient if you could easily understand what time zone was recorded in the recorded program. It is very convenient if a desired scene in each recorded program being reported is automatically reproduced in sequence.

  A function provided in the broadcast program recording / reproducing apparatus 1 of the present embodiment to meet such a demand is an extraction / playback function. For example, as illustrated in Fig. 4 (a), in the "Pro Baseball Bulletin" broadcast from 20:54 on ch3 on January 15, from 20: 55: 2 to 20:57:30 For 2 minutes and 28 seconds (this period is referred to as scene A). Also, for example, as illustrated in FIG. 4A, in the “9 o'clock news” broadcast from 21:00 on ch2 on the same day, 2 from 21:45:43 to 21:48:10 It is assumed that news about the Nagoya team's game was made for 27 minutes (this period is called Scene B). Also, for example, as illustrated in FIG. 4A, in the “daily event” broadcast from 23:00 on ch3 on the same day, 5 from 23:20:00 to 23:25:10 It is assumed that the news about the Nagoya team's game was made for 10 minutes (this period is called scene C). Also, for example, as illustrated in FIG. 4A, in “Sports News” broadcast from 23:40 on ch1 on the same day, 7 minutes from 23:55:28 to 24: 3: 20 It is assumed that during the 52 seconds (this period is called scene D), reports on the Nagoya team game were made. Also, for example, as illustrated in FIG. 4A, in “Sports & Entertainment” broadcast from 7:30 on ch2 on the following 16th, from 7: 35: 2 to 7:39:20 For 4 minutes 18 seconds (this period is called Scene E), and reports on the Nagoya team game were made.

  On the other hand, for example, the user can download and obtain the extracted reproduction information as shown in FIG. 4B from the server 7, or can create it himself. Then, by reproducing the recorded program based on the extracted reproduction information, the scenes A to E can be sequentially reproduced.

  In the extracted reproduction information, as shown in FIG. 4B, for each of the scenes A to E, the reproduction order, channel, broadcast date, start time and end time of the target scene, program title, target scene Time, identifier, etc. Further, the name of the extracted reproduction information (in this example, “1 / 15,16 Nagoya team news digest”) is also included.

  By playing the recorded program based on the extracted reproduction information in FIG. 4B, the moving image “1 / 15,16 Nagoya Team News Digest” is reproduced. That is, as shown in FIG. 4C, the data of each scene is read out sequentially from the corresponding recorded data in the designated order (in this example, the order of scenes A, B, C, D, and E). Played. In the present embodiment, “digest” includes not only the general meaning of summary but also the meaning of extracting at least one specific scene from the entire recorded program.

  The extracted reproduction information shown in FIG. 4 is merely an example. The user can freely create the extracted reproduction information and use it by himself or upload it to the server 7 so that it can be used by other users. Conversely, the user can selectively download and use the extracted reproduction information stored in the server 7 and created by another user. Of course, the user can also download and use the extracted reproduction information created and uploaded to the server 7 by himself / herself.

  When the user wants to download the extracted reproduction information from the server 7, the user downloads the data of the extracted reproduction information list screen 50 illustrated in FIG. 5 from the server 7 by connecting to the server 7 and performing a predetermined operation. Display on the display screen. The extracted reproduction information list screen 50 includes information frames 51, 52, 53, 54,... Indicating the extracted reproduction information that are created by various users, uploaded to the server 7, and downloadable. Listed. In each information frame 51, 52..., The name and content of the corresponding extracted reproduction information are displayed, and a download button 56 is displayed.

  When there is extracted reproduction information to be downloaded and used, the user downloads the extracted reproduction information by pressing the download button 56 in the information frame indicating the extracted reproduction information (for example, a touch operation via a touch panel). Can be saved and used later.

  As is clear from the example of FIG. 5, CM can be included in the scene as the extracted reproduction information (see, for example, information frames 53 and 54). That is, regardless of whether the program is a specific program (content) or CM, the extracted reproduction information can be created and used for all the recorded contents.

(2-2) Extracted Reproduction Information Creation Function The broadcast program recording / reproducing apparatus 1 of this embodiment has an extracted reproduction information creation function for creating extracted reproduction information. An outline of the extracted reproduction information creation function will be described with reference to FIGS.

  In order to create the extracted reproduction information, first, it is necessary to select a program from which a scene is to be extracted. When the user performs an operation (details are omitted) of selecting a desired recorded program to be included in the extracted reproduction information from the entire recorded program, a creation preparation screen 90 as illustrated in FIG. 6A is displayed on the display screen. Is displayed.

  The creation preparation screen 90 includes a playback screen 91 for playing back the selected recorded program, a playback button 92, a pause button 93, a rewind button 94, a fast forward button 95, a return button 96, and a new creation. A button 97 and an additional creation button 98 are displayed.

  When the playback button 92 is pressed, the selected recorded program is played back on the playback screen 91. When the pause button 93 is pressed during reproduction, the reproduction is paused. The playback position can be returned by pressing the rewind button 94, and the playback position can be advanced by pressing the fast forward button 95. When the return button 96 is pressed, the display content on the display screen can be returned to the previous screen.

  In order to create the extracted reproduction information, either the new creation button 97 or the additional creation button 98 may be pressed. When the new creation button 97 is pressed, new extracted reproduction information can be created. When the new creation button 97 is pressed, a scene extraction execution screen 120 illustrated in FIG. 7A is displayed.

  When an additional creation button 98 is pressed on the creation preparation screen 90, a scene to be played back can be added to the extracted playback information that has already been created and saved (stored) in the memory 32 or the storage unit 26. Specifically, when the additional creation button 98 is pressed, a list of registered extraction / playback information is displayed, and when extraction / playback information to be added to which a scene is to be added is selected, an example shown in FIG. The edit screen 110 of the selected extraction target reproduction information to be added is displayed.

  On the edit screen 110, a selection completion button 111, a return button 112, an addition selection check box 113, and a deletion selection check box 114 are displayed. When the return button 112 is pressed, it is possible to return to the previous screen. When a check box of a scene to be deleted is selected from the deletion selection check boxes 114 and the selection completion button 111 is pressed, information on the selected scene is deleted from the extracted reproduction information.

  When a check box of a position where a scene is to be newly added is selected from the additional selection check boxes 113 and the selection completion button 111 is pressed, the selected position is determined as an additional position, and the content of the display screen is shown in FIG. To the scene extraction execution screen 120 illustrated in FIG.

  The scene extraction execution screen 120 includes a playback screen 121 for playing back the selected recorded program, a playback button 122, a pause button 123, a rewind button 124, a fast forward button 125, a start position button 126, An end position button 127, a registration completion button 128, a cancel button 129, a voice recognition button 131, an image recognition button 132, and a text recognition button 133 are displayed.

  The start position button 126 is a button for designating the start position of the scene to be added, and the end position button 127 is a button for designating the end position of the scene to be added. When the cancel button 129 is pressed, it is possible to return to the previous screen.

  When the user presses the playback button 122 to start playback of the recorded program and then presses the start position button 126 at a desired timing, a scene start flag is set at the playback position. Thereafter, when the end position button 127 is pressed, a scene end flag is set at the playback position at that time. As a result, a scene between the scene start flag setting position and the scene end flag setting position is determined as one piece of extracted reproduction information. If there are other scenes you want to add, you can add them in the same way. When the registration completion button 128 is pressed, creation of the extracted reproduction information is completed, and the created extracted reproduction information is registered (new registration or update registration). At this time, a registration completion screen 140 as illustrated in FIG. 7B is displayed on the display screen.

  The registration completion screen 140 in FIG. 7B is selected as a scene addition position between the two currently registered scenes in the editing screen 110 illustrated in FIG. 6B, and one scene exists there. As a result, it has been shown that extracted reproduction information including information of three scenes is generated and registered.

The scene to be registered can be determined using any one of voice recognition, image recognition, and text recognition in addition to the above method.
For example, when the voice recognition button 131 is pressed on the scene extraction execution screen 120 (see FIG. 7B), a text prompting voice input is displayed on the display screen and a voice input waiting state is entered. At this time, when a user utters a voice or the like and inputs a desired voice via the sound input unit 23, a recognition process for the inputted voice is executed. For example, the input voice is converted into text. Then, from the selected recorded program, a scene of a predetermined time zone including at least a scene where the recognized sound is emitted (for example, a performer utters the word) is extracted, and is extracted as one piece of reproduction information. It is determined.

  Note that the speech to be recognized may be input by a method other than the method of inputting directly through the sound input unit 23. For example, audio data to be recognized may be input from outside via data communication or a memory card. In addition, for example, a scene from which a desired sound to be recognized can be generated from a recorded program, and the sound generated in the scene may be recognized. In addition, the recognizable voice is not limited to a specific word but may be a specific sound or music, a voice of a specific person, or the like. In the case of a voice of a specific person, for example, by analyzing the voiceprint of the person, a scene where the voice of the same voiceprint is uttered (that is, a scene where the person speaks) is extracted based on the analysis result. be able to.

  Also, for example, when the image recognition button 132 is pressed on the scene extraction execution screen 120 (see FIG. 7B), text prompting the designation of the image is displayed on the display screen, and the image designation wait state is entered. At this time, when the user selects a desired image (for example, a specific person's face or a specific article) in the recorded program by a touch operation on the touch panel or the like, recognition processing of the selected image is executed. . As a specific method of selecting an image, for example, when a person appears in a recorded program, it is paused and the person is circled, or when a car appears in a recorded program And touching the image of the car. When the image recognition processing is executed for the selected image, a scene in a predetermined time zone including at least a scene in which the recognized image is displayed is extracted from the recorded program and determined as one piece of extracted reproduction information. Is done.

  Further, for example, when the text recognition button 133 is pressed on the scene extraction execution screen 120 (see FIG. 7B), a screen for prompting text input is displayed and a text input waiting state is entered. At this time, when the user inputs a desired text, a scene in a predetermined time period including a scene in which the input text is displayed is determined as one of the extracted reproduction information from the selected recorded program. The In addition, the scene where the text here is displayed includes a scene where the text is displayed as a caption in the case of a caption broadcast program.

  As described above, the user can extract the scene to be included in the extracted reproduction information from the selected recorded image by various methods, and can create the extracted reproduction information including the extracted scene.

(3) Explanation of Various Processes by Recording / Reproducing Application Next, various processes performed when the control unit 31 of the control unit 30 executes the recording / reproducing application in the broadcast program recording / reproducing apparatus 1 will be described with reference to FIGS. This will be described using each flowchart. Note that the above-described extraction / reproduction function is realized mainly by the extraction / reproduction process of FIG. 9, and the above-described extraction / reproduction information generation function is mainly realized by the extraction / reproduction information generation process of FIG.

(3-1) Recorded Program Reproduction Process The recorded program reproduction process shown in FIG. 8 is a process for selecting and reproducing a desired recorded program from the recorded programs recorded in the storage unit 26. When the recorded program playback process of FIG. 8 is started, the control unit 31 determines whether or not there is a predetermined search request operation for the recorded program in S10. If there is no search request operation, in S15, a normal selection receiving process is executed to determine a recording program to be reproduced, and the process proceeds to S70. The normal selection receiving process of S15 is a process of receiving a direct selection of a recorded program to be played back by the user. Specifically, for example, a list of recorded programs (for example, a recorded program list screen in FIG. 3) is displayed on the display screen, and a user selects a desired recorded program from the list, and the selected recorded program is reproduced. There is a method of determining the target.

  If it is determined in S10 that the search request operation has been performed, the requested search method is determined in S20. In the present embodiment, recorded programs can be searched using text search or voice search. The user can specify which method is used for searching.

  If text search is designated as the search method, input of text to be searched is accepted in S25. In S30, a recorded program including the search target text input in S25 is searched. Various concrete search methods for recorded programs based on text are conceivable. For example, a recorded program whose search target text is included in the program name may be searched, or a recorded program whose search target text is included in the EPG information may be searched. Also, for example, when subtitle broadcast data is included in the broadcast data, it is recorded as a recorded program including the subtitle broadcast data. In this case, the recorded program includes the search target text in the subtitle broadcast data. May be searched.

  In S35, a list of text search results is displayed. That is, a list of search results of recorded programs including the search target text is displayed on the display screen. In S40, the selection operation of the recording program to be reproduced by the user for the search result displayed in the list in S35 is accepted.

  If voice search is designated as the search method in S20, input of the search target voice is accepted in S45. The user can input the search target voice via the sound input unit 23 by various methods such as uttering the search target voice.

  In S50, the speech input in S45 is recognized, and the recognized speech is set as a search target. The specific method of the speech recognition process is the same as the speech recognition method described above in the case where the extracted reproduction information is generated using speech recognition.

  In S55, a recorded program including the search target (that is, recognized voice) set in S50 is searched. In S60, a list of search results obtained in S55 is displayed. That is, the search result of the recorded program including the audio to be searched is displayed as a list on the display screen. In S65, the selection operation of the recording program to be reproduced by the user for the search result displayed in the list in S60 is accepted.

  In S70, the recorded program selected by the user in S15, S40, or S65 is reproduced on the display screen. Specifically, the recorded data of the selected recorded program is read, and the recorded program is reproduced based on the recorded data.

  In S75, it is determined whether or not the user has made a protection request (for example, pressing a protect button (not shown)) for the selected recorded program. For each recorded program, the user can request a protection setting for preventing the recorded program data from being deleted from the storage unit 26.

  If the user makes a protection request for the selected recorded program, the recorded program is protected in S80. Thus, the recorded program can be continuously stored in the storage unit 26 unless a predetermined release operation for releasing the protection setting is performed.

(3-2) Extraction / Reproduction Process Next, the extraction / reproduction process of FIG. 9 will be described. The extraction / reproduction process shown in FIG. 9 is a process for reproducing a recorded program based on the extracted reproduction information. When a predetermined extraction / reproduction request operation is performed by the user, the control unit 31 executes the extraction / reproduction process of FIG.

  When starting the extraction / reproduction process of FIG. 9, the control unit 31 determines in S110 whether or not the user has made a connection request to the server 7, that is, whether or not a download request from the server 7 for the extraction / reproduction information has been made. Judging.

  If the connection request to the server 7 (request for downloading the extracted reproduction information from the server 7) has not been made, the process proceeds to S140. In S140, the extracted reproduction information stored in the broadcast program recording / reproducing apparatus 1 is displayed in a list on the display screen. Specifically, the extracted reproduction information list screen 50 illustrated in FIG. 5 is displayed.

  In S145, the selection reproduction information selection operation to be performed by the user on the extracted reproduction information list screen 50 is accepted. In S150, the extracted reproduction information selected in S145 is designated as a reproduction execution target.

  If it is determined in S110 that a connection request to the server 7 (extracted reproduction information download request from the server 7) is made, the process proceeds to S115. In S115, data of the extracted reproduction information list screen 50 (see FIG. 5) is acquired from the server 7. In S120, the extraction reproduction information list screen 50 is displayed based on the data acquired in S115. In this case, the extracted reproduction information list screen 50 displays a list of extracted reproduction information that can be downloaded from the server 7.

  In S125, the selection reproduction information to be downloaded by the user for the extraction reproduction information list screen 50 is received. In S130, the extracted reproduction information selected in S125 is downloaded from the server 7 and stored in the memory 32 or the storage unit 26. In S135, the extracted reproduction information downloaded in S130 is designated as a reproduction execution target.

  In S155, it is determined whether or not the user has issued a reproduction instruction based on the extracted reproduction information for the extracted reproduction information designated as the reproduction execution target in S135 or S150. When the reproduction instruction is not given by the user, the extraction reproduction process is terminated. If the reproduction process is performed by the user, it is determined in S160 whether or not the extracted moving image object corresponding to the extracted reproduction information is stored in the memory 32 or the storage unit 26.

  The extracted moving image object is moving image data obtained by combining moving image data of scenes indicated by the extracted reproduction information. In the present embodiment, the extracted moving image object is generated and stored when the processing of S180 to S185 is executed.

  When the extracted moving image object corresponding to the specified extracted reproduction information is stored, the stored extracted moving image object is read and reproduced. In this case, the process of reading the recorded program data corresponding to each scene based on the extracted reproduction information is not performed, and the extracted moving image object generated and stored as one independent moving image data is reproduced. Note that the process of playing the extracted moving image object that has already been generated and stored also corresponds to an example of the process of the extraction / playback unit of the present invention.

  On the other hand, if the extracted moving image object corresponding to the designated extracted reproduction information is not stored in S160, the process proceeds to S170. In S170, the recorded program is extracted and reproduced in accordance with the procedure described with reference to FIGS. 4B and 4C in accordance with the designated extraction and reproduction information. Extraction reproduction means reading and reproducing each scene to be reproduced set as extraction reproduction information in the order set.

  After the extraction / reproduction based on the extraction / reproduction information is completed, in S175, it is determined whether or not the user has requested to save the series of extracted and reproduced moving images. If no storage request is made, the extraction / reproduction process is terminated. If a save request is made, an extracted moving image object is generated based on the specified extracted reproduction information in S180. That is, the moving image data of each set scene to be reproduced is extracted, and the moving image data is combined so that the respective scenes are continuously reproduced in the specified order, thereby extracting one independent moving image data. Create a video object. In step S185, the generated extracted moving image object is stored in the memory 32 or the storage unit 26.

(3-3) Extracted Reproduction Information Creation Processing Next, the extracted reproduction information creation processing of FIG. 10 will be described. The extracted reproduction information creation process shown in FIG. 10 is a process for creating extracted reproduction information for a recorded program recorded in the broadcast program recording / reproducing apparatus 1. When the extraction reproduction information creation process of FIG. 10 is started, the control unit 31 accepts a user's selection operation of a recorded program to be extracted from a scene to be extracted and reproduced in S210. When the user performs a selection operation (details are omitted) of a recorded program having a scene to be included in the extracted reproduction information from the entire recorded program, the creation preparation screen (see FIG. 6A) is displayed on the display screen in S215. ) Is displayed.

  In S220, it is determined whether or not a request for creating extracted reproduction information has been made by the user. Specifically, it is determined whether any of the new creation button 97 and the additional creation button 98 has been pressed. If a request to create extracted reproduction information is made (that is, if any of the buttons 97 and 98 is pressed), it is determined in S225 which of the buttons 97 and 98 is pressed.

  When the new creation button 97 is pressed, a scene extraction execution screen (see FIG. 7A) is displayed on the display screen in S230. In S235, a scene extraction process is executed. Details of the scene extraction processing in S235 are as shown in FIG. That is, when the process proceeds to the scene extraction process, it is determined in S310 whether there is an option designation for the scene extraction method. Specifically, it is determined whether any one of the voice recognition button 131, the image recognition button 132, and the text recognition button 133 is pressed on the scene extraction execution screen.

  When there is no option designation, that is, when a basic scene designation operation is performed by pressing the start position button 126 and the end position button 127, a scene extraction process based on the basic scene designation operation (usually S315) (Extraction process) is executed to extract a scene. When the scene extraction is completed by pressing the registration completion button 128, the process proceeds to S240 (FIG. 10).

If there is an option designation, it is determined in S320 which of the voice recognition button 131, the image recognition button 132, and the text recognition button 133 has been pressed.
If the voice recognition button 131 is pressed, a voice input is accepted in S325. In S330, a voice recognition process for the voice input in S325 is executed. The speech input method, the type of speech that can be recognized, the recognition method, etc. are as described above.

  In S335, a scene in a predetermined time period including at least a scene in which the sound recognized in S330 appears is extracted from the recorded program selected as the extraction target. As a result, the extracted scene is determined as one piece of extracted reproduction information.

  If the image recognition button 132 is pressed in S320, the process proceeds to S340. In S340, the selection input of the recognition target image by the user is accepted. In S345, recognition processing of the image selected in S340 is executed. In S350, a scene in a predetermined time period including at least a scene in which the image recognized in S345 is displayed is extracted from the recorded program selected as the extraction target. As a result, the extracted scene is determined as one piece of extracted reproduction information.

  If the text recognition button 133 is pressed in S320, the process proceeds to S355. In S355, an input of text by the user is accepted. In S360, a scene in a predetermined time zone including the scene in which the text input in S355 is displayed is extracted. As a result, the extracted scene is determined as one piece of extracted reproduction information.

  After the scene extraction process of FIG. 11 (that is, the process of S235 of FIG. 10), the process proceeds to S240 (FIG. 10). In S240, information indicating the scene extracted by the scene extraction process in S235 is generated as extracted reproduction information and newly registered (stored in the memory 32 or the storage unit 26).

  In detail, this new registration is executed when the registration completion button 128 in the scene extraction execution screen 120 is pressed. If there are a plurality of extracted scenes, the extracted order is registered as a playback order as it is by default. However, the order in which a plurality of scenes are reproduced can be arbitrarily changed by a user operation. When new registration is performed in S240, the registration completion screen 140 illustrated in FIG. 7B is displayed on the display screen. That is, the detailed contents of the extracted reproduction information newly created and registered by the user are displayed.

  If the additional creation button 98 is pressed in the creation preparation screen 90 (see FIG. 6A) in S225, the process proceeds to S245. In S245, a list of registered extracted reproduction information is displayed.

  In S250, selection of the extraction reproduction information to be added to which a new scene is to be added is accepted. When the extraction reproduction information to be added is selected by the user in S250, the editing screen 110 (see FIG. 6B) of the selected extraction reproduction information to be added is displayed on the display screen in S255.

  In S260, the selection input of the position which adds a new scene by a user is received. Specifically, as described with reference to FIG. 6B, a selection operation for the additional selection check box 113 in the editing screen 110 is accepted. When the scene addition position is selected, the scene extraction execution screen 120 (FIG. 7A) is displayed on the display screen in S265. In step S270, a scene extraction process is executed. Details of the scene extraction processing in S270 are as shown in FIG.

  In S275, information indicating the scene extracted by the scene extraction process in S270 is added to the additional position specified in S260, thereby updating the registered content of the extraction reproduction information to be added. After the update registration in S275, the process proceeds to S280, and the extracted reproduction information registered for update is uploaded to the server 7.

  Note that the uploading to the server 7 in S280 may be performed when the user is inquired of the necessity before uploading and the user gives an upload instruction. FIG. 10 shows a process of adding a scene to the existing extracted reproduction information as shown in S245 to S275 as a process when the additional creation button 98 is pressed, but the illustration is omitted. However, processing for deleting a scene is also performed in response to a request from the user. Specifically, as described with reference to FIG. 6B, the user requests to delete the scene, by an input operation on the editing screen 110 (specifically, a pressing operation of the deletion selection check box 114).

(3-4) Recorded Program Deletion Process Next, the recorded program deletion process of FIG. 12 will be described. The recorded program deletion process shown in FIG. 12 automatically deletes the recorded program according to the data amount of all the recorded programs (in other words, according to the free capacity of the storage unit 26). Process.

  When the recorded program deletion process of FIG. 12 is started, the control unit 31 determines whether or not the data amount (total amount) of all the recorded programs recorded in the storage unit 26 is equal to or greater than a specified value in S410. If the total amount is less than the specified value, the recorded program deletion process is terminated. If the total amount is greater than or equal to the specified value, in S415, the processing target is limited to a recorded program that is not protected by the user among all the recorded programs. As a result, in the following processing (S420 and subsequent steps), protected recorded programs among the recorded programs are excluded from the processing target.

  In S420, it is determined whether there is a program capable of reducing the image quality among the recorded programs to be processed. The program capable of lowering image quality means a recorded program that has a low reproduction frequency after being recorded and has not yet been subjected to the image quality reduction processing. The image quality reduction process is a process executed in S440.

  A method for determining whether or not the reproduction frequency is low can be determined as appropriate. For example, a recorded program having the number of reproductions of one or less may be determined as a recorded program having a low reproduction frequency. Of course, it may be determined according to other criteria.

  In addition, the fact that the frequency of reproduction is low as one of the conditions for a program capable of reducing image quality is just an example. For example, if the frequency of reproduction is high, it can be considered that if the view is changed, there is less need for the user to watch and save again. Therefore, contrary to the above example, high playback frequency may be one of the conditions for a program capable of reducing image quality.

  If it is determined in S420 that there is a program capable of reducing the image quality, the oldest recorded program (that is, the oldest broadcast date) is extracted in S435. In step S440, the image quality reduction processing is executed on the extracted recorded program. The image quality reduction processing is processing for reducing the data amount of a recorded program by reducing the image quality of the recorded program. After the image quality reduction process is executed in S440, the process returns to S410.

  If it is determined in S420 that there is no program capable of reducing the image quality, the oldest program out of all recorded programs is extracted in S425. In step S430, the EPG information and the designated storage information of the extracted recorded program data are stored in the storage unit 26 as past recorded program information corresponding to the recorded program, and other information ( Video data, etc.) is deleted. After S430, the process returns to S410.

  In the process of S430, the designated storage information is information designated as information that should be preserved in addition to the EPG information, and can be arbitrarily designated by the user. For example, if the video data is to be deleted but the audio data is to remain, it can be left by specifying the audio data in the designated storage information.

(4) Effect of Embodiment According to the broadcast program recording / reproducing apparatus 1 of the present embodiment described above, the user can easily and efficiently obtain a desired scene from the recorded program by acquiring the extracted reproduction information. Can be played.

  The extracted reproduction information can be acquired by various methods. For example, it is possible to extract and reproduce by using the extracted reproduction information created by the user himself / herself. Since the extracted reproduction information once created can be stored, once created, the extracted reproduction information can be extracted and reproduced afterwards by using it again and again.

  It is also possible to download the extracted reproduction information stored in the server 7 and extract and reproduce the recorded program according to the extracted reproduction information. The server 7 can upload and store the extracted reproduction information created by each user not only from the user of the broadcast program recording / reproducing apparatus 1 but also from other unspecified users. Each user can download and use desired extraction / reproduction information from various types of extraction / reproduction information created by various users.

  Further, in the present embodiment, by using the extracted reproduction information, not only can the extraction reproduction according to the extracted reproduction information be executed, but also the moving image data of each scene constituting the extracted reproduction information can be combined. One independent extracted video object can be generated. For this reason, for example, by generating an extracted moving image object for certain extracted playback information, it becomes impossible to acquire the extracted playback information thereafter, or an original recording that includes a specific scene constituting the extracted playback information Even if the program data itself is deleted, as long as the extracted moving image object remains, the scene corresponding to the extracted reproduction information can be reproduced easily and efficiently.

  Further, in the present embodiment, as a method of searching for a desired recorded program to be reproduced from all recorded programs, a method other than the method of displaying the list of recorded programs illustrated in FIG. In addition, text search and voice search can be used (see FIG. 8). Therefore, the user can search for a desired recorded program efficiently and quickly by using text search or voice search.

  In addition, when the user himself / herself creates extraction / playback information, new extraction / playback information can be newly created, as well as new scene information can be added to the extracted / playback information that has already been created and stored, and vice versa. The existing extraction / reproduction information can be updated by deleting the scene. Therefore, it is possible to create and save extracted reproduction information that more meets the needs of the user.

Further, only the CM or the CM can be mixed as an extraction / reproduction target. For this reason, CMs of a specific genre can be collected from recorded programs and can be extracted and reproduced.
Moreover, when creating the extracted reproduction information, a desired scene to be reproduced can be extracted by various methods (see FIGS. 7 and 11). Specifically, a recorded program can be extracted by a user operation while actually reproducing it (S315), or a desired scene can be extracted using voice recognition, image recognition, or text recognition (S320-). ). Therefore, the user can extract a scene using an appropriate extraction method according to the content and number of scenes to be extracted, and can efficiently and quickly create desired extracted reproduction information.

  In the present embodiment, the broadcast receiving unit 21 corresponds to an example of a receiving unit of the present invention, and the control unit and the storage unit 26 correspond to an example of a recording unit of the present invention. The control unit 31 that executes various programs corresponds to an example of an information acquisition unit, an extraction / playback unit, a scene specification unit, an information generation unit, and a moving image data generation unit of the present invention.

  Further, the processes of S135 and S150 correspond to an example of the process executed by the information acquisition unit of the present invention, and the processes of S165 and S170 correspond to an example of the process of the extraction reproduction unit of the present invention, and S235, S270 and The process of S475 corresponds to an example of the process executed by the scene specifying unit of the present invention, the processes of S240, S275, and S480 correspond to an example of the process of the information generating unit of the present invention, and the process of S180 is the present invention. This corresponds to an example of processing executed by the moving image data generation unit.

[Other Embodiments]
As mentioned above, although embodiment of this invention was described, this invention can take a various form, without being limited to the said embodiment.

  (1) As a specific procedure for creating extracted reproduction information, the above embodiment has been described with reference to FIG. 10, but the creation procedure shown in FIG. 10 is merely an example. The extracted reproduction information can be created by various methods.

  For example, a certain event or event may be broadcasted and then a part of the content may be introduced in a news program. In that case, a scene for a predetermined period including a scene introduced in the news program may be extracted from the entire broadcasted program, and created and registered as extracted reproduction information.

  As a more specific example, it is assumed that a professional baseball game is broadcasted in the evening, and then the result of the game is broadcast on a news program at midnight. In the news program, it is assumed that, for example, the scoring scenes on the back of the fifth round and the scenes on the end of the ninth round of the game are introduced. In such a case, for each of two scenes introduced (broadcast) in the news program, a scene for a predetermined period including at least the scene is extracted from the recorded game broadcast program broadcast in the evening, and the extraction is performed. Each scene may be created and registered as extracted reproduction information.

  Such a creation method can be realized by the control unit 31 executing, for example, the extracted reproduction information creation process shown in FIG. That is, when the extraction reproduction information creation process of FIG. 13 is started, the control unit 31 accepts a selection operation of a base recorded program by the user in S460. The base recorded program is a recorded program for designating a scene to be extracted, and corresponds to a news program in the above example.

  In S465, a base scene extraction process is executed. This base scene extraction process is a process for extracting a base scene from the base recorded program selected in S460 in accordance with the user's scene selection operation.

  In S470, an operation for selecting a recorded program to be extracted by the user is accepted. In S475, a scene for a predetermined period including at least the scene is extracted for each scene extracted in S465 from the recorded program to be extracted in S470. The predetermined period here can be determined as appropriate. In S480, extraction reproduction information including the scene extracted in S475 is created and registered.

  By making it possible to create the extracted reproduction information by such a method, for example, in the above-mentioned professional baseball example, the user views the news program and reaches the score scene of the fifth time (for example, the fifth time If you want to know more about the entire process from the start of the game to the scoring) or if you want to see the stadium after the match (for example, the hero interview) By appropriately adjusting, it is possible to meet the demand of the user.

  (2) Playback of a recorded program is not limited to the recorded program playback process shown in FIG. 8, and may be performed by various methods. For example, a recorded program may not be reproduced as it is, but may be reproduced with an arrangement.

  Various arrangements can be considered as to what kind of arrangement is added to the recorded program. For example, a recorded CM may be deleted or replaced with another CM. In the case of CM replacement, the content of the CM after replacement may reflect the intention of the manufacturer of the broadcast program recording / playback apparatus 1, the vendor of the application, or the user, for example. For example, when the user notifies the server 7 that the CM of a specific vehicle type of a specific car manufacturer is to be viewed in a concentrated manner, when playing a recorded program, the server 7 does not record the CM recorded in the CM scene. You may make it receive and reproduce | regenerate the newest CM of the specific vehicle type.

  In addition, if the recorded CM is basically played back as it is, but the contents at the time of recording are already out of date and the latest version of the CM is currently aired, the latest version of the CM is displayed. You may make it replace with CM.

  Further, it can be searched and specified by various methods as to which period in the recorded program the CM is inserted. For example, when data indicating the CM position (temporal position) is added to the broadcast data, the CM position may be determined based on the data. Further, for example, the determination may be made based on sound in a recorded program. For example, the start / end timing of the CM may be determined based on the presence or absence of a specific sound (for example, a specific word) that is assumed to be a CM in a recorded program.

  Further, as a method of arranging recorded programs, for example, a method of temporarily erasing a part of sound and images in the program and asking the user about the erased contents in a quiz format is conceivable. For example, if it is determined based on the image recognition process that a certain person has appeared for the first time after starting playback of a recorded program, playback is automatically paused and the person's face is temporarily deleted. You may ask the user who the person is in a quiz format. Then, the normal reproduction may be resumed after a certain period.

  If the name of the person who has recognized the image can be acquired by communication with the server 7 and the voice of the user can be recognized by voice recognition, the user can be paused until the user answers correctly, If the user answers correctly, he / she outputs some compliment, or conversely, if a wrong answer continues for a predetermined number of times, outputs some pessimistic words, or returns to normal playback when the user says, for example, “Descent”. A more advanced arrangement can be realized.

  (3) Another user may be able to give an evaluation to the extracted reproduction information uploaded to the server 7. The extracted reproduction information may be selected and downloaded with reference to the evaluation value.

  (4) The number of channels that can be recorded simultaneously in the broadcast program recording / playback apparatus is not particularly limited. Further, it is not always necessary to record all the channels that can be recorded simultaneously. The user may arbitrarily set the recording timing and channel. In the first place, the present invention can also be applied to an apparatus capable of recording only one channel at a time.

  (5) The content of the extracted reproduction information is not limited to the content shown in FIG. It is sufficient that the content can be understood at least in which time zone of which program (which channel).

  Further, the method of generating the extracted reproduction information is not limited to the method described in the above embodiment (particularly FIG. 11). For example, if information on the channel and time zone of the scene to be extracted is known, the information may be generated based on that information. For example, when information about a time zone of a scene in which a specific person appears is provided from a broadcast station, favorite extracted reproduction information can be generated based on the information.

As long as it is possible to provide information as to which scene of which recorded program is to be reproduced from among the recorded programs, the method of generating the extracted reproduction information and the specific content thereof are not limited.
In the above-described embodiment, the method for obtaining the extracted reproduction information has been described with respect to the method for downloading and obtaining from the server 7 and the method for using the extracted reproduction information stored in the broadcast program recording / reproducing apparatus 1. However, these acquisition methods are merely examples. For example, the extracted reproduction information may be read from a storage medium (for example, a USB memory or a flash memory card) in which the extracted reproduction information is stored and used. Further, for example, if there is a provider (for example, a broadcasting station) that provides various variations of extracted reproduction information for a fee or free of charge, desired extraction / reproduction information may be acquired from the provider and used.

  (6) When playback based on the extracted playback information is performed, if the corresponding extracted video object is not stored (S160: NO), the extracted video object may be first generated and played back. . That is, when a negative determination is made in S160, first, the process of S180 is executed to reproduce the extracted moving image object, and then the storage necessity determination of S175 is performed, and the storage process of S185 is performed as necessary. You may do it.

  (7) Although each process shown in FIGS. 8 to 13 has been described as being realized by the control unit 31 executing a program in the above-described embodiment, a part or all of these software processes are performed, for example, You may implement | achieve by various logic circuits, such as ASIC and FPGA.

  (8) The present invention can be applied to any device capable of receiving and recording a broadcast signal. For example, if the PC 9 and the mobile communication terminal 11 have a function of receiving and recording a broadcast signal, the present invention can be applied to the PC 9 and the mobile communication terminal 11.

  (9) In the above embodiment, an example in which the recording / playback application is installed in the broadcast program recording / playback apparatus 1 and various processes are performed by the broadcast program recording / playback apparatus 1 has been described. The broadcast program recording / reproducing apparatus 1 may be accessible from the PC 9 or the mobile communication terminal 11 by sharing the reapparatus 1 with another apparatus (for example, the PC 9 or the mobile communication terminal 11). That is, the broadcast program recording / reproducing apparatus 1 is accessed from the PC 9 or the portable communication terminal 11 to receive reproduction data based on the extracted reproduction information, and the received reproduction data is reproduced on the PC 9 or the portable communication terminal 11. You may be able to do that. If the extracted video object is stored in the broadcast program recording / reproducing apparatus 1 from the PC 9 or the portable communication terminal 11, the data of the extracted video object is downloaded from the broadcast program recording / reproducing apparatus 1 to the PC 9 or the portable communication terminal 11. It may be possible to play it back.

  The generation and storage of the extracted reproduction information and the upload to the server 7 may be performed from the PC 9 or the mobile communication terminal 11. Basic operations of the broadcast program recording / reproducing apparatus 1 such as deletion of a recorded program recorded in the broadcast program recording / reproducing apparatus 1 may be performed remotely from the PC 9 or the mobile communication terminal 11.
