  FIG. 4 is a functional block diagram showing a configuration example of the content display device according to the first embodiment of the present invention. The content display device includes an operation input unit 23, a display control unit 24, a display unit 25, a search server unit 26, a content database (DB: Data Base) 27, and a search index DB 28.

  The operation input unit 23 is a user operation input unit such as a remote controller, a mouse, a face orientation / line-of-sight detection device, and the like.

  The display control unit 24 can continuously reproduce a plurality of contents simultaneously and display them on the display unit 25. For example, the display control unit 24 generates a GUI content as shown in FIG. Further, the title of the content and the attributes described later may be displayed in text. These texts are not always displayed but may be displayed for a certain period of time. Further, more detailed bibliographic information such as a synopsis of viewing content may be displayed.

  The search server unit 26 searches for content to be displayed in the first display area and content to be displayed in the second display area. The content displayed in the first display area is searched for the same content with an attribute different from the attribute of the first display area based on the selected content ID, and the result is output to the display control unit 24.

  The content DB 27 is a DB that stores content such as broadcast programs, videos distributed on the Internet, and still images.

  The search index DB 28 is an attribute DB assigned to each content ID. FIG. 5 is a table showing an example of contents stored in the search index DB 129. In this example, the attribute name is stored, but the attribute ID may be stored.

  FIG. 6 is a diagram showing an initial screen when a movie is taken as an example. Here, a table of attributes is held for each of five categories (genre, appearance, director, theme, mood) for one content (referred to as category attributes), but the present invention is not limited to this. Here, the theme indicates the theme of the content such as the environment and animals, and the mood indicates the sensitivity of the content such as harassment and healing. Other categories include screenwriters, original authors, production countries, content length (time), factors classified based on text sentences such as content synopsis and impressions, and the presence / absence / tempo of music. It is also conceivable that the image features of the content such as the acoustic features, color, brightness, and motion amount of the content are used as attributes. These attributes can be newly added as appropriate.

Details of the search server unit will be described. Here, an example will be described in which five categories (genre, appearance, director, theme, mood) are held in the database and search is performed for each category.
1. Genre: Search for content having the same genre attribute (for example, SF, action, etc.).
2. Performer: Search for content having the same performer attribute (name).
3. Director: Search for content with the same director attribute (name).
4). Theme: Search for content with the same theme attributes (eg, law, animals, environment, war, life, etc.).
5). Mood: Search for content with the same mood attributes (eg, crying, exhilarating, irritating, laughing, etc.).

  The first display area content search (interesting content search) will be described. In the present embodiment, a display example shown in FIG. 6 is assumed as an initial screen to be displayed before moving to the display form shown in FIG. FIG. 6A is an example displayed by category, and FIG. 6B is an example displayed by genre. Of course, the initial screen is not limited to these. In addition, the category name may be displayed as shown in FIG. 6 or only the content may be clearly indicated without specifying the category name. Alternatively, new content or recommended content on the content provider side may be displayed on the initial screen. Alternatively, the initial screen may be displayed by displaying the content that the user first viewed in the first display area of FIG.

  In the present embodiment, the first display area is searched based on the category (genre, appearance, director, theme, attribute for each mood (category attribute) given to the content selected on the initial screen, The search result is displayed in the first display area.

  Here, FIG. 6B will be described as an initial screen. For example, when the user selects “animation” on the initial screen, content having the attribute “animation” in the category (genre) is searched from the DB, and these search results are displayed in the order of similarity to the selected content. To do. Therefore, for example, as shown in the upper part of FIG. 9A, content having the same attribute “animation” is displayed in the first display area. Here, these are called interesting contents. A ranking method when there are a plurality of contents of “animation” having the same attribute will be described later.

  The second display area content search (related content search) will be described. The content having the same attribute for each of the five categories (genre, appearance, director, theme, mood) is searched and displayed in the second display area, for example, as shown in the lower part of FIG. However, the category displayed in the first display area is excluded. Thereby, in the second display area, it is possible to find content that is not high in similarity but is related to the selected content, that is, that is unexpected. Here, these are referred to as related contents.

Here, the processing flow of the search server unit will be described with reference to FIG.
FIG. 7A is a flowchart showing processing when content is selected on the initial screen. In step S1, when the user selects content, the process starts. First, in step S2, the search server unit acquires the ID and category attribute of the selected content from the search index DB. Next, in step S3, the search server unit searches the search index DB for content having the same category attribute, and outputs the result to the display control unit (search for first display area content). In step S4, the display control unit displays the content in the display area. Next, in step S5, based on the content ID acquired in step S2, the search server unit displays from the search index DB for each category shown in the table of FIG. 5 (however, displayed in the first display area). Content with the same attribute is searched for (exclude category) (search for second display area content). At this time, the content searched in step S3 is excluded. In step S <b> 6, the display control unit displays the contents in the second display area in a category order (for example, genre, performer, director, theme, mood) that has been determined in advance. In step S7, the process ends.

  FIG. 7B is a flowchart showing processing when content in the first display area is selected. In step S11, the process starts when the user selects content in the first display area. Next, in step S12, process 1 (steps S5 and S6) in the flowchart of FIG. 7A is performed, and the process ends in step S13.

  FIG. 7C is a flowchart showing a process when content in the second display area is selected. In step S21, when the user selects content in the second display area, the process is started. Next, in step S22, process 2 (steps S2, S3, S4, S5, S6) in the flowchart of FIG. 7A is performed, and the process ends in step S23.

  Through the above processing, the contents of the first display area and the second display area are updated each time content is selected.

  In the present embodiment, content having the same attribute is searched for and displayed for each category shown in the table of FIG. At this time, a ranking method for determining which content is displayed when a plurality of contents having the same category attribute are displayed will be described with reference to the flowchart of FIG.

  FIG. 8 is a flowchart showing the ranking process in the search server unit. In step S31, the process starts when the user selects content. First, in step S32, the search server unit acquires the ID and category attribute (for example, genre: animation) of the selected content from the search index DB. Next, in step S33, the search server unit searches the search index DB for content having the same category attribute. Next, in step S34, the search server unit sorts the contents searched in step S33 in order of similarity with the selected content as the head, and outputs the result. In step S35, the process ends. Here, the order of similarity is, for example, in descending order of the number of matches of all category attributes between the search results (genre: content having the category attribute of animation) and the selected content (in order from the highest number of matches). Rearranges. Alternatively, the similarity of the image feature amount and the acoustic feature amount of the content of the search result can be considered.

  A display example will be described. First, with reference to FIG. 9, the switching of content when content is selected in the first display area will be described. In FIG. 9A, the content C55 selected by the user and the content C52 having the same category attribute (genre “animation”) are displayed in the first display area. In this example, only two contents having the same category attribute are displayed, but the number of contents to be displayed is not limited to this. Further, in the second display area, as related content of the content C55, the content C15 having the same category attribute (performer “XX”), the content C28 having the same category attribute (director “ΔΔ”), the category attribute (theme “ The content C33 with the same “animal”) and the content C41 with the same category attribute (feeling “cry”) are displayed.

  Within the first display area, the user can view content one after another. For example, when the content C52 is selected in FIG. 9A, the first display area is switched as shown in FIG. 9B, the selected content C52 moves to the center, and the content C55 that has been viewed up to now is displayed. Moving to the left side, a new content C58 having the same “animation” attribute is displayed on the right side.

  On the other hand, in this example, once viewed content can be viewed again. That is, content can be viewed one after another in the reverse direction. For example, when the content C55 is selected in FIG. 9B, the state returns to the state of FIG.

  In this example, the content selection method is such that, for example, the content is moved to the center when the content is selected in FIG. 9A. However, the selection method is not limited to this. Absent. For example, in FIG. 9A, when the left content C52 is selected, the content may be shifted counterclockwise, and when the right content C58 is selected, the content may be shifted clockwise. Thus, the user continuing to select content in the first display area indicates that the user is interested in the attribute (“animation” in FIG. 9), and the first display area It functions as an interest window.

  In addition, the content in the second display area is switched in conjunction with the user selecting the content in the first display area. For example, in FIG. 9A, the user is currently viewing the content C55, and related content C15, C28, C33, C41 of the content C55 is displayed in the second display area. Next, when the user selects the content C52 in the first display area, the related contents C14, C22, C37, and C44 of the content 52 are linked to the second display area as shown in FIG. 9B. Is displayed.

  Next, content switching when content is selected in the second display area will be described with reference to FIG. The user can also select content in the second display area. At this time, both the content in the first display area and the content in the second display area are switched in conjunction with the action of the user selecting the content in the second display area.

  For example, in FIG. 10A, the user is currently viewing the content C52, and the related contents C14, C22, C37, and C44 of the content C52 are displayed within the second display area. Next, when the user selects the content C37 in the second display area, the content C37 moves to the center in the first display area as shown in FIG. At this time, it is indicated that the user's interest has shifted from (genre “animation”) to (theme “environment”), and therefore, the category attribute of the first display area is switched from “animation” to “environment”. . That is, the contents C37 and C32 in the first display area of FIG. 10B are contents having the category attribute “environment”. The text information indicating the attribute need not be displayed.

  Furthermore, at the same time as the content C37 moves to the center of the first display area, the second display area is switched to the related contents C18, C25, C56, and C43 of the content C37.

  As described above, when the user continues to select content in the second display area, the opportunity to encounter content from various viewpoints increases.

  By the way, as a method for switching the content, a method that allows the user to easily understand that the content that has been displayed so far has been switched is desirable. For example, instead of switching in an instant, the content that has been displayed until then gradually fades out, the newly displayed content fades in, or the trail of which content has moved to where it can be seen You may add various effects.

<Second Embodiment>
In the first embodiment described above, if the user continues to select content in the second display area, the opportunity to encounter content from various viewpoints increases. On the other hand, since the viewpoint changes one after another, it is good when the user has not yet narrowed down to the viewpoint (content) that he / she wants to see, but there is a drawback that it is not possible to narrow down even if the content is approaching to some extent .

  Therefore, in the second embodiment, when the user is approaching the content that the user wants to see, the mode is switched to the “narrowing mode”, and when the content that the user still wants to see is not found, the mode is switched to the “search mode”. The content search method can be changed to a method of narrowing down based on the attribute that interests you.

  FIG. 11 is a functional block diagram showing a configuration example of a content display device according to the second embodiment of the present invention. The difference from the content display device according to the first embodiment shown in the functional block diagram of FIG. 4 is that the content display device according to the present embodiment has a mode switching unit 29 in the search server unit 26.

  The mode switching unit 29 switches to the “narrowing mode” when the user is approaching the content that the user wants to see, and switches to the “search mode” when the content that the user still wants to see is not found. For the switching timing, a switch button may be prepared in the operation input unit 23 so that the user can switch. Alternatively, in the search mode initially, in the category attribute included in the content selected by the user, the number of times the content including the same category attribute is selected or the time length for viewing the content including the same category attribute exceeds a certain threshold. Then, the search mode may be automatically switched to the refinement code.

  As a result, in the process in which the user selects the content displayed in the first display area and the second display area, whether the user is approaching the desired content or is still wondering, When the search method can be switched and the narrowing mode is entered, the content displayed in the first display area is narrowed down based on the attribute that interests the user, and it becomes possible to find content that matches the user's preference. .

Next, the processing flow in the narrow-down mode and the search mode will be described.
The processing flow of the search server unit in the search mode is the same as that in the first embodiment, and the processing is the same as in FIG.

  FIG. 12 is a flowchart showing the processing of the search server unit 26 in the narrow-down mode. In step S41, the process starts when the user selects content in the second display area. First, in step S42, the search server unit 26 acquires the ID and category attribute of the searched content from the search index DB 28. Next, in step S43, content that includes both the category attribute acquired in step S42 and the category attribute of the content in the first display area acquired in step S2 of FIG. 7A is searched (in the narrow-down mode). Search for first display area content). In step S44, the display control unit 24 displays the content in the first display area, and in step S45, the process ends.

  FIG. 13 is a diagram illustrating a display example of the display unit in the narrow-down mode. In the state shown in FIG. 13A, when the user selects the content C44 in the second display area, the first display area has so far been in the first display area as shown in FIG. 13B. The contents 52 and 53 having both the attribute “animation” and the attribute “harahara” of the content 44 selected by the user are displayed. (The content 52 originally has the attributes of “animation” and “harahara”, and therefore the content of the second display area is the same as that in FIG. 13A at this point. The content of the second display area is narrowed down by the attribute of the content in the second display area, and of course, if the user selects the content 53 next time, the content in the second display area is the content related to the content 53. Note that, here, an example in which only two contents having the same attribute are displayed is shown, but the number of contents to be displayed is not limited to this.

<Third Embodiment>
FIG. 14 is a functional block diagram showing a configuration example of a content display device according to the third embodiment of the present invention. The difference from the content display device of the first embodiment shown in the functional block diagram of FIG. 4 is that the content display device of the present embodiment has an operation input unit 23, a display control unit 24, The display unit 25, the content DB 27, and the communication unit 31 are arranged, and the search server 26, the search index DB 28, the communication unit 33, and the content management server 34 are arranged on a server on the network. This eliminates the need to store a large amount of content in the terminal 30. The content is acquired by streaming, for example.

  In the present embodiment, when the user instructs acquisition of content, the ID of the content is transmitted to the server 32, and streaming playback of the selected content starts. For example, an HTML browser is mounted on the display unit 25, and the server 32 converts the search result into HTML data and transmits it to the terminal 30, and the display unit 25 performs browsing processing and displays it. Content information and search result HTML data are exchanged over, for example, the HTTP protocol.

  Further, the content DB 27 is also provided on the terminal 30 side, and the content to be displayed on the initial screen is acquired in advance from the content management server 34 and recorded. Note that the user's content selection history may be analyzed, and content with high accessibility may be acquired from the content management server 34 in advance. Alternatively, new content or recommended content may be transmitted from the server 32 side at regular intervals.

  Further, by placing the search server unit 26 on the server 32 side, the search server 26 can accumulate a plurality of content selection actions. That is, the related content search using so-called collaborative filtering can be performed. For example, if the user A likes the content X, the content Y preferred by another user B who likes the content X is set as the related content in the second display area. It becomes possible to display. Therefore, the content to be displayed in the second display area is searched based not only on the attribute given to the selected content but also on the other content that is often selected together with the selected content. Also good.

<Fourth embodiment>
FIG. 15 is a functional block diagram showing a configuration example of a content display device according to the fourth embodiment of the present invention. The difference from the content display device of the first embodiment shown in the functional block diagram of FIG. 4 is that the display unit 25 has a plurality of display devices (a first display device 35 and a second display device 36). It is a point.

  In the present embodiment, the content (interesting content) displayed in the first display area in the first embodiment is displayed on the first display device 35. In addition, the content (related content) displayed in the second display area in the first embodiment is displayed on the second display device 36.

  FIG. 16 is a diagram illustrating a display example according to the fourth embodiment. For example, the first display device 35 shown in FIG. 16A is a large screen TV or the like placed in a living room, and the second display device 36 shown in FIG. 16B is a mobile display ( It is assumed that the display part of the remote control may be used. Of course, the display format, size, and number of contents are not limited to this. Although not shown, the content title and category attributes may be displayed in text.

  By separating the display areas in this way, the user can concentrate on viewing only the content that he / she is interested in on the first display device 35, and only when he wants to see related content, the second display device 36 can be viewed. Can be operated on the local display.
