Description

  The present invention relates to an electronic apparatus capable of recording and reproducing information and a storage / reproducing method.

  Along with the evolution of recording system functions represented by price reduction of storage devices and improvement of storage density, a large amount of information can be stored on a daily basis, that is, programs can be recorded. For example, the time shift machine function allows the user to record the entire favorite channel / time zone and watch the program for up to about one week retrospectively without making a recording reservation for each program.

  On the other hand, when the user selects a viewing target program to be viewed from among the recorded programs, the number of programs that are candidates for the viewing target program is large, and thus the user needs for the search function of the recorded program increase. ing.

JP 2012-70194 A JP 2010-41413 A

  Since many programs that are candidates for viewing are recorded, the user is required to determine which program to narrow down the programs to be viewed. For this reason, the user is interested in watching commercials for promotion of new programs, that is, new programs, and short programs prepared for the next notice of continuous programs that will be completed multiple times. There are many cases of narrowing down the programs to be viewed.

  However, a user who has missed the mission is forced to view the program as a candidate for continuous viewing in order to determine a program to be continuously viewed. In order to narrow down programs to be continuously viewed, it is preferable to refer to program descriptions and related information. The program description can be acquired from, for example, an EPG (electronic program guide) or a program guide in a television program introduction column of a newspaper. The related information can be acquired as, for example, word-of-mouth information (recommended information) provided by an SNS (social network service) or an information magazine. Nevertheless, in the program reorganization period in which many new programs are broadcast, the determination of programs to be viewed continuously becomes a heavy burden on the user.

  An object of the present invention is to provide an electronic device and a storage / reproduction method capable of recording and reproducing information.

  In the storage and reproduction method of the embodiment, a specific recorded content for promotion is extracted from recorded programs, and a program main part that matches specific information corresponding to the specific recorded content is searched and searched. A display signal is output so that an input screen for receiving an instruction input of a reproduction instruction for the main program or specific recording content can be displayed.

An example of the instruction | indication input screen display in the storage / reproducing apparatus which concerns on embodiment is shown. 1 shows an example of a storage / reproduction device (electronic device) according to an embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a storage / reproduction device (electronic device) according to the embodiment. The elements and configurations described below may be realized by software by a microcomputer (processing device, CPU (Central Processing Unit)) or may be realized by hardware.

  In the following description, a program may be referred to as a stream, content, or information. The program is composed of video and audio and music attached to the video. In addition, the video includes at least one of a moving image, a still image, or text (information represented by characters or symbols indicated by a coded code string).

  Acquisition of a program recorded by the storage / playback apparatus can be realized by receiving a broadcast transmitted from a program supplier (broadcast station) using, for example, a spatial wave (radio wave). The program may also be acquired by a program distributor (distributor) that uses a network such as an optical fiber (cable) or an Internet Protocol communication network. The program acquisition may also be a reading (downloading) of a streaming video (stream) held by a program provider (content server) on the network. Furthermore, the program can be acquired (reproduced) by video transfer technology using a network function (reproduction (acquisition) via a network of programs held by other devices.

  1 includes a reception unit 102, a demodulation unit 103, an MPEG processing unit (video / audio signal processing unit) 104, an output unit 105, a system control unit (main control block) 106, an operation unit 107, a recording A processing unit 110, a recorded program management unit 111, a number extraction unit 112, a number metadata management unit 113, a program link information generation unit 114, a number reproduction control unit 115, a communication control unit 116, and the like are included.

  The receiving unit 102 is connected to the antenna 101. The output unit 105 is connected to a display (display unit) 109 that displays video and a speaker 108 that reproduces sound / audio. The communication control unit 116 is connected to the service server 201 that holds metadata for scene search via the network NTW. Note that the speaker 108 and / or the display 109 or at least one of them may be in non-contact with the storage / playback device 1 and acquire video or audio / sound by, for example, wireless communication. Further, the speaker 108 and the display 109 may be integrated with the storage / playback apparatus 1.

  A television broadcast signal input from the antenna 101 to the receiving unit 102 is converted into an IF (intermediate frequency) signal by the receiving unit 102. Demodulation section 103 extracts a digital signal (TS: transport stream) from the IF signal and outputs it to MPEG processing section 104.

  The MPEG processing unit 104 separates the TS into a video component (video), an audio / audio component (audio), and SI (Service Information) for EPG display, and decodes the video (video) / audio / audio (audio). To do. The decoded video data and audio / audio data are output from the output unit 105 to the speaker 108 and the display 109, respectively.

  The system control unit (main control block) 106 controls the operation of the above-described elements and configurations. The system control unit 106 also receives various control commands corresponding to control inputs (operation instructions) from a remote terminal device (remote controller) RM received by the operation unit 107 and portable terminal devices represented by tablet PCs and smartphones. Output. The control command is a command for instructing, for example, recording (storage) of a television broadcast (program), reproduction of a recorded (stored) program, or the like.

  The recording processing unit 110 performs loop recording (time shift machine recording) of an arbitrary number of programs in the storage device H1 connected to the recording processing unit 110. Although loop recording depends on the recording rate (data size at the time of recording), for example, programs for 6 channels can be recorded for about one week, for example. Note that the user (viewer) can arbitrarily set the number of channels for loop recording, the time zone, and the recording rate.

  The recorded program management unit 111 extracts and manages program information of programs held in the storage device H1 (stored in the storage device H1). The recorded program management unit 111 stores the extracted program information in the connected recorded program information database L1.

  The number extraction unit 112 extracts a number (notice) that is a “program promotion” part prepared integrally with the program entity (the main part of the program) in the program held in the storage device H1. The program entity indicates a state in which the program is separated from the program broadcast in one broadcast time zone, and includes, for example, a CM that is broadcast integrally.

  Banban is a short-form program prepared for the next notice of a CM-type program for the promotion of a program (new program) that will start broadcasting or a continuous program that is completed multiple times. In many cases, the program is broadcast at the end of each broadcast of a continuous program that is completed multiple times, but is broadcast at substantially any timing.

The number extraction unit 112 extracts the number of programs whose one program is composed of all the numbers, excluding them from the extraction target. The program excluded from the extraction target includes re-broadcast of the (n-1) th program broadcast on the same day or the previous day prior to the nth broadcast of the continuous program. That is, it is preferable to determine that the (n-1) th broadcast broadcast before the nth broadcast of a certain program is a program numbered program. In addition, the program is broadcast at a relatively high frequency on the day when the new program starts broadcasting or for several days to several weeks before the start of broadcasting. Therefore, it is preferable that the number extracting unit 112 can identify a plurality of numbers corresponding to the same program as one number by referring to the number metadata (number information) held by the service server 201. The number extraction (notice) extraction by the number extraction unit 112 is, for example,
[A] Next time, ...
[B] The next highlight is ...
[C] New program announcement ...
And the like (telop (subtitles) and voice) can be specified by video (sound) recognition technology that has already been put into practical use. The extracted keywords are stored as numbering information (numbering metadata) in the numbering information database L2 connected to the numbering metadata management unit 113 described below. Number metadata (number information) is various data that can be used to specify a program entity (program main part) corresponding to the number, for example, program name (program ID), broadcast station name, broadcast start date and time, Includes at least airtime. Information necessary for extracting the number and number metadata (number information) can also be obtained from the service server 201 via the network NTW. That is, the service server 201 holds information on whether or not there is a number attached to the program entity for an arbitrary program. In addition, when there is a number, the service server 201 holds number metadata indicating the position on the time axis of the program so that the storage / playback apparatus 1 can refer to it. The number metadata includes at least data indicating that the section from MM minutes SS seconds to mm minutes ss seconds is a number when the program start time is 00 minutes 00 seconds on the program time axis. .

  Note that the storage / reproduction device 1 may have a function of copying the extracted number portion to another storage area. That is, by copying the extracted numbered part to another storage area, it becomes easy to delete the main part when deleting only the main part of the recorded program. The number portion has link information corresponding to the main part of the recorded program. Thereby, when deleting the main part of the recorded program, it is also possible to delete the number corresponding to the main part of the program (associated with the main part) in an integrated manner (substantially simultaneously). . Accordingly, the storage area of the storage device H1 can be used effectively.

  The number metadata management unit 113 manages number metadata (number information) extracted by the number extraction unit 112 or acquired from the service server 201 via the network NTW. That is, the numbering metadata management unit 113 stores the numbering metadata extracted by the numbering extraction unit 112 or acquired from the service server 201 in the numbering information database L2. The number metadata stored (held) in the number information database L2 can be referred (read) at any timing through the number metadata management unit 113 as necessary (based on a user instruction). The contents of the number information database held by the number information database L2 are illustrated in FIG. The contents of the number information database held by the number information database L2 are number metadata, number recording position information in the storage device H1, and link information with the program entity (main part). The link information is generated by the program link information generation unit 114 described below.

  The program link information generation unit 114 collates the numbering metadata read by the numbering metadata management unit 113 from the numbering information database L2 with the program substance (main part) and generates link information. As described above, the link information is information indicating an association between a program number and a program entity (main part). The link information is information that can identify the corresponding entity program, and includes at least the recorded content ID in the storage device H1 managed by the recorded program management unit 111, for example. Further, when two or more storage devices H1 are available, the link information includes at least information (MAC (Media Access Control) address) for identifying the storage device H1 in which the corresponding program is recorded.

  As will be described later with reference to FIG. 4 or FIG. 5, the number reproduction control unit 115 controls reproduction of program entities or numbers held in the storage device H1. That is, the number reproduction control unit 115 reproduces the number and the program substance at an arbitrary timing according to the selection instruction (remote control operation) by the user. The number reproduction control unit 115 controls the reproduction of the program entity or the number with an arbitrary reproduction pattern according to the user instruction at the time of reproducing the number or the program entity held in the storage device H1. The reproduction pattern includes, for example, only the program, only the program entity, or each program entity corresponding to the program. As shown in FIG. 4, the number reproduction control unit 115 presents, for example, a recorded program list format so that the user can select whether to reproduce the number or the program substance. Thereby, based on the user's operation (control instruction from the remote controller Rm), the program or the program entity can be reproduced. As shown in FIG. 5, the number reproduction control unit 115 can present a list that displays only the numbers, and can start reproduction of the program entity specified by the user's operation.

  The communication control unit 116 controls data exchange with the service server 201 via the network NTW so that information necessary for the number extraction held by the service server 201 and metadata of the number can be acquired.

  FIG. 2 shows an example of the control flow in terms of software.

  The program is recorded (stored) in the storage device H1 by the recording process of the recording processing unit 110 by a user operation (instruction input by the user), execution of a recording reservation, or the like. After the recording of the program in the storage device H1 is completed, the recorded program information is notified to the recorded program management unit 111, and the recorded program information held in the recorded program information database L1 is updated. The program recording information stored in the recorded program information database L1 includes at least information such as a recorded program (content) ID, a program title, a broadcast start date and time, a broadcast station name, and a broadcast time [201].

  The recorded program management unit 111 refers to the number information (number metadata information) held (managed) by the number metadata management unit 113 to determine whether there is number information corresponding to the program that has been recorded. Match. Note that the numbering information held by the numbering metadata management unit 113 includes, for example, at least a program title (program name), a program title ID, a broadcast start date and time, a broadcast station (channel) name, and broadcast time information [202 ].

  The recorded program management unit 111 includes program title (program name), program title ID, broadcast start date / time, broadcast station name and broadcast time information of the program that has been recorded, and number information managed by the number metadata management unit 113. And compare. The recorded program management unit 111 determines the matching status from the comparison result [203].

  When all of the number information managed by the number metadata management unit 113 matches all of the comparison targets for the recorded program [203-YES], [204] is continuously executed. That is, the number metadata management unit 113 receives information necessary for the mutual link between the number and the program entity from the recorded program management unit 111 and stores it in the number information database L2 [204].

  On the other hand, if at least one of the program title (program name), the broadcast start date / time, the broadcast station name, and the broadcast time information among the above-mentioned number information does not match, the recorded program management unit 111 [203-NO] It is determined that there is no order corresponding to the entity. Therefore, the recorded program management unit 111 stores in the number information database L2 that the number corresponding to the program entity does not exist and ends [205].

  FIG. 3 shows an example of the stored contents of the number information database held by the number information database L2. Note that the storage content 301 illustrated in FIG. 3 is an example, and the recording format and arrangement, the number of management information, and identification (classification) are arbitrary.

  The storage content 301 of the number information database includes a plurality of storage areas 311 to 318. The first storage area 311 stores a numbered title ID, for example. The second storage area 312 stores a storage start position. The third storage area 313 stores the storage end position. The fourth storage area 314 stores a program entity (main part) title. The fifth storage area 315 stores a channel (broadcast station name). The sixth storage area 316 stores the broadcast start date and time. The seventh storage area 317 stores the broadcast time (hour / minute). The eighth storage area 318 stores link information.

  More specifically, the first storage area 311 holds information associated with the program entity (main part) title stored in the fourth storage area 314, that is, the numbered title ID. The second storage area 312 and the third storage area 313 indicate areas in which the program numbers specified by the start time and end time stored in the fifth storage area 315 to the seventh storage area 317 are recorded. . That is, the second storage area 312 holds the recording start position in the numbered storage device H1 corresponding to the specified program. Similarly, the third storage area 313 holds the recording end position in the numbered storage device H1 corresponding to the specified program. The eighth storage area 318 holds link information generated by the program link information generation unit 114 described above.

  FIG. 4A shows an example of a user interface (UI) screen display that is presented in, for example, a recorded program list format so that the user can select (instruct input) whether to reproduce a program or a program entity. Note that the UI screen display 401 illustrated in FIG. 4A is an example, and the display format and arrangement, and the number and identification (classification) of information to be displayed are arbitrary.

  The UI screen display 401 shown in FIG. 4A includes, for example, a classification (genre) display area 411, a determination button display 412 that can input a reproduction instruction of the main part (program substance), and a number that can input a reproduction instruction of a notification (notice). A playback button display 413, a title display area 420, and the like are included. The number reproduction button display 413 corresponds to an operation of any of a plurality of color keys ([blue] key, [red] key, [green] key, and [yellow] key) prepared for the remote controller Rm, for example. It is preferable. Hereinafter, in FIG. 4A, it is assumed that an on state (operation input) is instructed on the number reproduction button display 413 corresponding to the operation of the [blue] key of the remote controller Rm.

  In the UI screen display 401 shown in FIG. 4A, the title display area 420 displays the title name of the recorded program. The title display area 420 includes, for example, first to fifth title bar displays 421-425 for five programs (five lines). FIG. 4A shows that there is a number for the titles displayed by the first title bar display 421 and the third title bar display 423. In other words, the title display area 420 displays a “Trail” display indicating that a number exists in a predetermined area of the corresponding title bar display for a title having a number. In the example shown in FIG. 4A, trail displays 431 and 433 are displayed on the first and third title bar displays 421 and 423, respectively.

  In the UI screen display shown in FIG. 4A, it is assumed that the display color of the outer frame (edge) of the title bar display focused (selected) by the operation of the remote controller Rm changes. Next, by operating the remote controller Rm to input an ON state to the enter button display 412, the program entity (main part) of the title displayed on the focused title bar display is reproduced. In addition, the display method of the focused title bar display is arbitrary. For example, the display color may be reversed, or the background color as the background of the character may be changed.

  When playing a number, the focus bar is displayed on the title bar display of the title to be played, and by operating the remote control Rm, the ON state is instructed and input to the number play button display 413. The program announcement is played. For example, when the [blue] key of the remote control Rm is assigned as a key for transmitting an ON signal to the number reproduction button display 413, the focus is placed on an arbitrary title bar display and the [blue] key is turned on. , The program announcement is played.

  As shown in FIG. 4B, an input button function that accepts an operation of the remote controller Rm as an instruction input can be incorporated in each of the number display (Trail) display, and number button displays 481 and 483 can be obtained. That is, in the UI screen display shown in FIG. 4B, the program displayed by the title bar display focused by the cursor operation of the remote controller Rm can be reproduced by turning on the enter key 412. Further, the number corresponding to the number button display 481 or 483 focused by the cursor operation of the remote controller Rm can be reproduced by turning on the enter key 412.

It is also possible to have Thereby, for example, it becomes possible to focus alternately between the column of title bar display and the column of number button display, and the operability is improved.

  As shown in FIG. 5, it is also possible to present a list for displaying only the numbers to the user, and start reproduction of the program entity specified by the user's operation. Further, the screen display (UI screen) 501 illustrated in FIG. 5 is an example, and the display format and arrangement, the number of management information and the identification (classification) are arbitrary.

  The screen display (UI screen) 501 shown in FIG. 5 displays that the list displays only the numbers (notices) in the classification (genre) display area 511.

  The screen display (UI screen) 501 includes, for example, a number reproduction button display 512 and a main part reproduction button display 513. Further, the screen display (UI screen) 501 includes a title display area 520 for displaying a number to be reproduced (notice) or a program entity (main part) title. The number reproduction button display 512 allows a reproduction instruction (operation input) to reproduce only the number to be input. Also, it is possible to input a main part reproduction button display 513 and a reproduction instruction (operation input) for reproducing the main part (program substance). The main part playback button display 513 is a color key prepared in the remote controller Rm, and preferably corresponds to, for example, an operation of a [red] key. As an implementation example of the user interface (UI), it can be assigned to any color key prepared in the remote controller Rm, for example, an operation input of any of the [blue] key, [green] key, and [yellow] key. It is.

  In the UI screen display 501 shown in FIG. 5, link button displays 531 and 533 are prepared for the titles displayed by the title bar displays 521 and 523 among the titles displayed by the title bar displays 521-525. The link button displays 531 and 533 indicate that, for example, links related to various information highly related to the program are prepared in the metadata held by the service server 201. The link is preferably, for example, information on performers appearing in the program, the name of the facility (store) used in the program, the location of the program, and the like. In addition, the link may be associated with information on other programs in which a certain performer appears, information on products sold by facilities (stores) used in the programs, and their popularity (selling information). preferable. Thereby, the user can acquire more information regarding the reproduced program by turning on the link button display 531 or 533.

  Note that the program link information is preferably generated for a program that is currently broadcast on time. In this case, the channel selection operation for viewing the corresponding program entity is facilitated from the order.

  In this way, by associating the recorded program (and the current program) with the program number / preliminary notice as program link information, the user can selectively switch between the program number / preliminary notice and the program entity for playback. It becomes. Accordingly, a new program search function can be provided in which the user can determine a viewing program from the recorded programs based on the number / notice.

  FIG. 6 shows an example in which a number protection control unit is added to the storage / playback apparatus (electronic device) shown in FIG. 1 to protect and delete only the number broadcast part when the program entity is deleted.

  In the storage / reproduction device 601 shown in FIG. 6, the number protection control unit 617 protects only the number broadcast part when deleting the program entity held by the storage device H1, and allows data from the storage device H1 to be deleted. Controls deletion of (program). That is, by controlling the number protection control unit 617, when deleting the data of an arbitrary program, the number broadcast part is protected without being deleted, for example, a drama completed by a plurality of continuous broadcasts. For example, when there are missed times (broadcasts), it is possible to view the number as a substitute for the digest.

  1 and 6 show examples in which the storage device H1, the recorded program information database L1, and the numbering information database L2 are provided, but the individual databases are the same storage device.
