Description

  The present invention relates to a storage type broadcast content recording and reproduction technique.

  In recent years, a storage-type broadcast service (also referred to as a server-type broadcast) service that allows content transmitted via broadcast waves and content distributed via the Internet to be temporarily stored in a broadcast receiving apparatus and viewed after the broadcast. Is considered. Also, on broadcast waves, the Internet, etc., metadata related to content is also distributed. The metadata includes program information related to each program, scene information related to each scene constituting the program, and the like.

  On the other hand, the storage capacity of large-capacity recording media (for example, hard disk drives) used for storing content has improved remarkably, and it has become possible to store hundreds of programs and hundreds of hours of broadcast content. .

For this reason, the number of contents to be accumulated continues to increase, and the viewer must select the contents he / she wants to see from among the enormous contents. Therefore, a method for presenting accumulated contents as a list has been proposed (Patent Document 1).
JP 2004-320608 A

  However, the list display of contents so far is limited to the program name. Therefore, it is impossible to know whether there is a scene of interest in each program, and further, to what time zone of the recorded program the scene of interest is only by displaying the list.

  Whether there is a desired scene can only be improved by a method in which the user selects an appropriately recorded program, starts playback, and searches for the desired scene.

  The present invention has been made in view of such a problem. By using content metadata, the user can not only reproduce the individual content but also the program desired by the user as well as the time zone of the scene desired by the user. It is intended to provide technology that can be easily grasped.

In order to solve this problem, for example, a digital broadcast receiving apparatus of the present invention has the following configuration. That is,
A broadcast receiving device that receives broadcast program content and metadata related to the content, and stores and reproduces the received content,
Storage means for storing program information relating to each program and scene information relating to each scene constituting the program included in the received metadata;
Input means for entering keywords;
The program information and scene information corresponding to the keyword input by the input means are searched from the storage means, the program and scene corresponding to the keyword are specified, and the time information of the scene specified for each program is set as time. Display control means for forming a display screen displayed in a strip shape along the axis.

  According to the present invention, the scene corresponding to the keyword is specified using the metadata, so that the user can easily grasp the time zone of the scene desired by the user from the accumulated content before actually reproducing the content. become able to.

  Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

<First Embodiment>
FIG. 1 is a block diagram of a broadcast receiving apparatus in the embodiment.

  In the figure, 101 is an antenna for receiving a broadcast signal, 102 is a receiving unit for selecting and demodulating the received signal, 103 is a communication I / F unit for a network including the Internet, and the broadcasting station via a communication line Broadcast content can be obtained from such servers. Broadcast contents from the reception unit 102 and the communication I / F unit 103 are input to the separation unit 104. Separating section 104 separates and outputs video / audio data (hereinafter referred to as AV data) included in the broadcast content and metadata (details will be described later) including program information and scene information included in the broadcast content. .

  Here, the broadcast content is stream data composed of video and audio, and is data encoded by an encoding method such as MPEG2. The metadata is data described by BML (Broadcast-Markup-Language), which is a page description language, and includes program information (program title, etc.), scene information, and the like.

  Reference numeral 105 denotes a large-capacity and randomly accessible storage device such as a hard disk device, an AV storage unit 106 that stores the AV data separated by the separation unit 106 as a file, and a metadata storage unit that stores metadata as a file 107. These AV storage unit 106 and metadata storage unit 107 are easy to understand when considered as folders (directories) secured in the storage device.

  Note that programs stored in the storage device 105 are instructed to be stored by the user. In the case of storing the directional content via the Internet, it is a case where a download instruction is given by accessing an Internet content server. Further, when accumulating a program via the receiving unit 102, it is assumed that a recording instruction or a reserved recording time is reached by the user. The recording instruction is given from the operation unit 110.

  In addition, in storage-type broadcasting (server-type broadcasting), content transmitted by broadcast waves and content distributed via the Internet are temporarily stored in the storage device 105, and the stored content is called when the user likes it. Can watch.

  Reference numeral 108 denotes an AV decoder for decoding the AV file stored in the AV storage unit 106. The AV decoder 108 converts an AV file into a video signal and an audio signal, and can be viewed by a user by outputting the AV signal to the display unit 111. The display unit 111 is a device that displays an image such as a liquid crystal display or a CRT. The audio signal is input to an amplifier, a speaker, etc. (not shown) and output as audio.

  Reference numeral 109 denotes a display screen generation unit that generates a signal for OSD (On Screen Display) according to metadata corresponding to each program stored in the metadata storage unit 107 and an operation instruction from the operation unit 110. And displayed on the display unit 111. The display screen generation unit 109, the operation unit 110, and the display unit 111 function as a user interface.

  A control unit 150 controls the entire apparatus, and includes a ROM, a RAM, and a microcomputer.

  The operation unit 110 is configured by various switches and buttons provided on the front surface of the apparatus, but may be a remote control using infrared communication or the like. Further, the display unit 111 is not integrated with the present apparatus, but the display unit 111 may be an existing display apparatus, and the present apparatus may simply include an AV output terminal.

  The outline of the apparatus according to the embodiment has been described above, and the following operation will be described in detail.

  First, a process of extracting program information and scene information as metadata will be described. The aforementioned BML file is described in a tag structure, and has a structure described in a text format between a start tag and an end tag. 2A and 2B are shown as specific examples of metadata. FIG. 4A is a specific example of program information metadata describing program information of broadcast content, and FIG. 4B is a specific example of scene information metadata describing scene information in the program. In the figure, a line number is assigned to each line, but it should be noted that it does not actually exist.

  First, the program information metadata will be described with reference to FIG. In the program information metadata, a program can be specified by a content reference ID (“crid” in the figure) which is a program-specific identifier that is a key of broadcast content. For example, “crid: //japan-dtv.or.jp/history_of_man_and_animals” on line [1] indicates that the broadcasting station is “japan-dtv” and the broadcasting content is “history_of_man_and_animals”. [2] After the line, the basic information for searching the program is described. The <Title> tag on the [3] line shows the program title “History of human beings and animals”, [4] line. The <Synopsis> tag indicates that the outline of the program is “History of Human and Animal History”. Further, referring to lines [5] to [8], the <Time> tag indicates that the program time is 30 minutes, and the <Genre> tag indicates that the program genre is “animal”. Then, by the <Keyword> tag described in the [9] line, it is determined that the free keyword is “cat”.

  In this way, various information for searching for broadcast content information can be obtained by the program information metadata. Further, the program information is not limited to the above, but also includes information such as the broadcast date and time of the program.

  Next, scene information metadata will be described with reference to FIG. The scene information metadata specifies a scene in the program by a segment ID ("S2" in the figure) as shown in the [1] line. [2] The content reference ID ("crid" in the figure) on the line identifies the program. Search information for performing a scene search is described from the [3] line to the [10] line. [4] The <Title> tag on the line describes the title of the scene ("Cat" in the figure), and the <Synopsis> tag on the [5] line describes the scene outline ("Sleeping Kitten" in the figure). ing. Furthermore, from [6] line to [8] line, the genre of the scene (“animal” in the figure) is described by the <Genre> tag. In the [9] line, a free keyword (“cat” in the figure) is described by a <Keyword> tag.

  Further, in the [11] line to the [14] line, time information indicating the time position of the scene in the program is described. For example, in the [12] line, the <MediaTimePoint> tag describes the relative position from the start of the program to the start time of this scene in terms of time (hour: minute: second, etc.). [13] The <MediaDuration> tag on the line describes the length of the scene in time (minutes, seconds, etc.).

  From the extracted information, the scene information is “Cat”, the start time of the scene is “5 minutes 08 seconds” from the start of the program, and the length of the scene is “20 minutes”. I understand.

  As described above, each scene in the broadcast content can be distinguished by the scene information.

  In digital broadcasting, when one program is focused on, program information metadata is repeatedly transmitted at appropriate time intervals. This is because the program information can be acquired even when the program is viewed from the middle.

  Also, scene information metadata is repeatedly transmitted at appropriate intervals, but when there is a change in the content of AV content, scene information corresponding to that is received. For example, when the subject changes from “cat” to “dog”, the scene information indicates that the scene has become “dog”.

  Next, storage processing in the AV storage unit 106 and the metadata storage unit 107 in the embodiment will be described.

  When AV data is stored as an AV file in the AV storage unit 106, it is naturally necessary to define the file name. In the present embodiment, the control unit 150 generates a unique serial number each time it is easily accumulated, for example, “00001”, “00002”... And uses it as a file name. In addition, although the example which uses a 5-digit number character as a file name is demonstrated, the number of digits and the method of numbering are not restricted to this. In short, it is only necessary to be able to uniquely identify.

  On the other hand, the metadata file name has a format in which numeric characters for newly identifying metadata are added to the corresponding AV file name. However, the following rules were given.

  First, it is assumed that only one program information is stored for one program, and the file name is AV file name + “−” + “00000”.

  For example, the file name of the program information whose AV file name is “00001” is “00001−00000”.

  When the scene information currently received for the program of interest is different from the previously received scene information, a numeric character added by “1” is added to the file name of the scene information. However, the first scene information of the program is unconditionally saved.

  Therefore, when the AV file name is “00001”, the scene information is “00001-00001”, “00001-00002”, “00001-00003”,.

  As a result, the AV data and the metadata (program information, scene information) are associated with each other. In summary:

  When the AV file name stored in the AV storage unit 106 is “01234”, the file name of the corresponding metadata in the metadata storage unit 107 is “01234-#####”. In particular, a file name with “####” being “00000” indicates program information, and a file name having “####” after “00001” is scene information.

  The above is an example for associating AV data, program information, and scene information, and each file may be managed by a method different from the above format. For example, an independent folder may be created for each program, and AV files, program information, and scene information may be stored therein. In this case, the AV file, program information, and scene information can be identified using the file extension. The file name of the identification information may simply be issued.

  In the apparatus according to the embodiment, when the user operates the operation unit 110 to specify AV content and a reproduction instruction is input, the control unit 150 starts decoding the corresponding AV data to the AV decoder 108. Request. In response to this request, the AV decoder 108 reads the corresponding AV file, sequentially decodes it, and outputs a video signal and an audio signal to the display unit 111. Since the reproduction process itself is a well-known technique, a process when the user gives a search instruction using the operation unit 110 will be described below. The AV storage unit 106 and the metadata storage unit 107 will be described assuming that a large number of broadcast contents have already been stored.

  When the user detects that the search instruction button (or switch) provided on the operation unit 110 is pressed, the control unit 150 gives the display screen generation unit 109 a start instruction related to the search.

  In response to this request, the display screen generation unit 109 generates search screen information, outputs it to the display unit 111, and accepts an instruction input from the operation unit 110.

  FIG. 3 is an example of a search screen displayed on the display unit 111. The search screen includes a free keyword input window 300 and a genre input window 350.

  As shown in the figure, the free keyword input window 300 is provided with input areas 301 to 303, in which free keywords input by the user using the operation unit 110 are displayed. The input field is switched by moving the cursor 310 in accordance with a movement key provided on the operation unit 110. In the input fields 301 to 303, a free character string for searching for a scene desired by the user can be input. When inputting a character string, a well-known kana-kanji conversion technique is used.

  The genre input window 350 is also provided with input fields 351 to 353. In these input fields, the user inputs a character string of the genre name of the program to be searched. Since the types of genres are generally limited, a character string may not be input but may be selected from predefined candidates such as a combo box.

  Here, it is assumed that the free keywords A, B, and C correspond to the genres A, B, and C, respectively.

In the case shown in the figure, the relationship between each column in the free keyword input window 300 and the genre input window 350 is as follows.
Free Keyword A: “Cat” ... Genre A: “Animal”
Free Keyword B: “Spaghetti”, “Ramen” ・ Genre B: “Cooking”
Free Keyword C: “Koto Seiryu” ... Genre C: “Sports”

  In addition, it is possible to input a plurality of character strings in one input field. Each character string is determined using a specific character (“,” in the figure) as a delimiter, and the search of each character string is treated as a logical sum.

  For example, for the favorite genre “dish”, “spaghetti, ramen” is designated as a free keyword, so that either “spaghetti” or “ramen” scenes are targeted for retrieval.

  Various input methods other than those shown in FIG. 3 are conceivable. For example, there are methods such as extracting keywords from a viewing program history or the like, extracting and presenting information such as free keywords and genres included in the scene while viewing the program, and allowing the viewer to select, but not limited to the above. Not what you want.

  When the user finishes inputting the genre and the free keyword as described above and the user operates the search start key of the operation unit 110, the display screen generation unit 109 searches the metadata storage unit 107. Then, the display screen generation unit 109 generates a content list having genres and scenes that match the search, and displays them on the display unit 111.

  As for the search at this time, regarding the genre, among the files stored in the metadata storage unit 107, the last five characters of the file name are “00000”, that is, the metadata of the program information, Search whether there is a corresponding character string. The free keyword is a file in which the first five characters of the files determined to have the same genre match, and the last five characters are other than “00000”, that is, the scene information is targeted. When there is a program specified by a genre and a free keyword, the display screen generation unit 109 creates a content list for the program. A specific example will be described below with reference to FIGS. 4 (a) and 4 (b).

  First, as shown in FIG. 4A, the display screen generation unit 109 obtains information on broadcast content name 401, broadcast content recording time 402, and recording date 403 from program information that matches the search of the metadata storage unit. Is displayed as shown in the figure. The content recording time 402 does not present the actual recording time itself, but has a bar graph (band) according to the recording time. Then, the display screen generation unit 109 extracts the time zone of the favorite scene of the free keyword from the scene information including the corresponding free keyword, and an area indicating the range of the time zone as shown in FIG. Is created by distinguishing it from the entire time zone. Typically, the color of the bar of the entire program and the color of the bar including the favorite scene are changed, but they may be distinguished by hatching, hatching, or the like.

  As a result, for example, when the free keyword “cat” as the favorite scene is specified in the genre “animal”, it is possible to distinguish and display in which time zone the scene related to “cat” of the entire program is. In the drawing, the favorite scene of “Cat” is one example, but when there are several divided scenes in time, the color of each part may be changed and displayed.

  By performing the above processing for the number of instructed genres and free keywords, a content list as shown in FIG. 5 is generated and displayed.

  FIG. 5 is an example in which a list is presented in order of recording date and time. The favorite scene 501, the favorite scene 502, the favorite scenes 503-1 and 503-2, and the favorite scenes 504-1 and 504-2 in FIG. A favorite scene 505 indicates a favorite scene of each broadcast content. The start time of each content is arranged in a line, and a scale indicating the time axis is provided on the bar graph indicating the recording time. The length of the recording time of each content and the length of the favorite scene time are set. Display for easy recognition.

  In order to realize the above, the processing procedure of the display screen generation unit 109 in the embodiment is shown in FIG. The display screen generation unit 109 will be described as including a memory for temporarily storing information.

  First, in step S1, the screen shown in FIG. 3 is displayed on the display unit 111, and the user inputs the free keyword and genre information, and waits for a search start instruction.

  When a search start instruction is given, the process proceeds to step S 2, and one piece of program information is read from the metadata storage unit 107. In the program information, the last five characters of the file name are “00000”.

  Next, in step S3, it is determined whether or not the read program information includes a character string of a genre input by the user. If not, the process proceeds to step S4, and it is determined whether or not all program information in the metadata storage unit 107 has been checked. If not, steps S2 and S3 are repeated.

  If it is determined that the character string of the genre input by the user is included in the description of the read program information, the process proceeds from step S3 to step S5.

  In step S5, scene information related to the program information is read. For example, if there is a character string of a genre designated by the user in the program information file name “01234-00000”, the metadata storage unit 107 has file names “01234-00001”, “01234-00002”, and so on. There will be scene information. Therefore, in this step S5, the one scene information is read out.

  In step S6, it is determined whether or not there is a free keyword designated by the user in the read scene information. If it is determined that there is a matching character string, the scene information can be used as information for specifying a program and a time zone desired by the user. Therefore, the scene information is temporarily stored in the display screen generation unit 109. Store in the memory (step S7).

  When the process proceeds to step S8, it is determined whether or not all scene information of the corresponding program has been checked. If not, the process from step S5 is repeated. If it is determined that all scene information of the corresponding program has been checked, the process returns to step S4.

  When the above process is repeated and the check for all program information is completed, the process proceeds to step S9.

  If there is scene information including a genre desired by the user and free keywords, the scene information (one or more) is stored in a temporary memory. Therefore, in step S9, it is determined whether or not the matching scene information exists in the temporary storage memory. If not, the process proceeds to step S10 and error processing is performed. Typically, this is a message display process indicating that there is no corresponding scene.

  If it is determined that the scene information exists in the temporary storage memory, the process proceeds to step S11, where program information is found from the first five characters of the file name of the scene information, and each program is shown in FIG. 4 (b). Display information to be generated is generated. The display information generated at this time is rearranged in order of the recording date of the program. Moreover, since the scene information includes time zone information of the corresponding scene, it is extracted. In step S12, the generated information is displayed (for example, see FIG. 5).

  Note that after the display screen of FIG. 5 is displayed, the user can select the desired content by operating the operation unit 110, and can arbitrarily specify either a favorite scene playback instruction or a normal playback instruction. . In the case of a normal playback instruction, playback starts from the top of the corresponding content, whereas in the case of a favorite scene playback instruction, only the favorite scene is played back. When there are a plurality of favorite scenes for one content, playback is started from the top of the contents, and when the playback of the corresponding favorite scene is completed, the next favorite scene is continuously played back.

  FIG. 6A shows an example of a playback screen when a favorite scene playback instruction is given. As shown in the drawing, the corresponding content bar is superimposed on the AV playback, and a playback position marker 603 indicating the current playback position is displayed.

  Further, after the reproduction, the list may be displayed so as to be recognized as the reproduced scene 604 by changing the color of the reproduced scene by presenting the list as shown in FIG. 6B.

  In addition, the list presentation of FIG. 5 of the present embodiment is an example in which it is easy to understand how many favorite scenes exist in one content. Furthermore, in order to easily understand which content has more favorite scenes, only the extracted favorite scenes may be listed as shown in FIG. In the case of FIG. 7, when the user gives a reproduction instruction, only a favorite scene is unconditionally reproduced.

  As described above, according to the present embodiment, the program information and scene information in the content obtained from the metadata and the preference information such as the free keyword and genre input by the viewer are collated, and the viewer's preference A list reflecting the scene is generated and displayed. As a result, before the content is actually reproduced, the viewer can easily find the genre and scene to be viewed from the accumulated content.

<Second Embodiment>
In the above embodiment, the example in which the display order of the content list is the order of the recording date and time has been described. Since the display time of each scene can be calculated from the scene information, it can be used. In the same program, when scene information desired by the user exists in discrete time zones, the total value of these time lengths is obtained. Since the apparatus configuration is the same as that of the first embodiment, the description thereof is omitted.

  FIG. 8 shows an example in which the content list is displayed in descending order of the total time length of the scene desired by the user (favorite scene). Further, as shown in FIG. 9, only the scene portion (favorite scene) desired by the user may be connected and displayed. Those skilled in the art can easily understand that such processing may be performed in step S11 in the flowchart of FIG.

<Third Embodiment>
The difference between the third embodiment and the first and second embodiments is that the list is displayed in a category classified by the user's desired genre. FIG. 10 shows a list display example of the third embodiment.

For example, it is assumed that the following information is input from the operation unit 110 as a free keyword and a genre.
Keyword A: "Cat" ..... Genre A: "Animal"
Keyword B: "Spaghetti", "Ramen" ... Genre B: "Cooking"
Keyword C: “Koto Seiryu” ... Genre C: “Sports” And, based on this condition, as a result of searching, the scene information obtained is
Content name Scene information “Cooking Ironman” ………… “Spaghetti”
“Gourmet trip” ………… “Ramen”
"Animals living in paradise" ... "Cats"
“History of mankind and animals” ……… “Cats”
“Grand Sumo Digest” ... “Koto Seiryu”
Suppose that

If the scene information extracted from each content is matched with the preference keyword input by the viewer, the genre into which each content is classified is
Contents Name Genre “Cooking Ironman”, “Gourmet Trip”… “Cooking”
"Animals living in paradise", "Human and animal history" ... "Animals"
“Great Sumo Digest“ ……… ”Sports“
Thus, the content corresponding to the genre can be classified, and the list of FIG. 10 can be created.

  If only favorite scenes corresponding to the genre are displayed, the list shown in FIG. 11 may be displayed. FIG. 11 shows an example in which only favorite scenes of each content (program) are listed together for each genre.

  As described above, the contents including more favorite scenes are listed and displayed in a list for each genre, so the user can easily determine how many scenes of the genre they like and can easily select the scenes with the highest demands. There is an effect of becoming. Further, in the case of the display in FIG. 11, it is possible to sequentially reproduce scenes of interest across different programs with one reproduction instruction, so that the convenience for the user can be further increased.

<Fourth Embodiment>
The difference between the fourth embodiment and the first to third embodiments is that, among the favorite scenes, when there are scenes in which a plurality of keywords are duplicated, the favorite scenes are more conspicuous. It is a point to present the list with emphasis.

  FIG. 12 shows a list presentation example of the fourth embodiment.

  Here, the process of emphasizing the favorite scene will be described.

  It is assumed that the user inputs “spaghetti” and “ramen” in one free keyword input field via the operation unit 110.

  Then, since the content name “Cooking Ironman” shown in FIG. 12 includes “spaghetti” which is a keyword of the favorite scene, a favorite scene 1201 is displayed. Then, in addition to “spaghetti” that is the keyword of the favorite scene, if the “ramen” that is the keyword of the favorite scene is also duplicated, as shown in the preference scene enhancement 1202, emphasize it more prominently. Present the list.

  As described above, when a scene is a scene where multiple keywords overlapped, the favorite scene is highlighted more prominently and the list is presented. This makes it easy to select a high-scene scene.

  The embodiments according to the present invention have been described above. The apparatus of the present invention is, for example, connected to an information processing apparatus such as a personal computer, a broadcast receiver, or a card having the function connected to a motherboard bus (such as a PCI bus), and the others are application programs (software). You can do that. In this case, the storage device 105 will use a hard disk installed in the information processing apparatus. When realized by software, the processing relating to the control unit 150, AV decoder 108, and display screen generation unit 109 in FIG. 1 may be realized by a computer program.

  Further, the computer program is usually stored in a computer readable storage medium such as a CD-ROM. Then, it can be executed by setting it in a computer reading unit (or CD-ROM drive in the case of a CD-ROM) and copying or installing it in the system. Therefore, it is obvious that such a computer readable storage medium falls within the scope of the present invention.
