Description

  The present invention relates to a content information display device in an installed TV (television) receiver, an in-vehicle TV receiver, a PC (personal computer), a portable terminal device, or the like, and in particular, a content having a function of selecting a desired content. The present invention relates to an information display device.

  In general, when a favorite program is broadcast, a method of recording the program on a recording medium is generally employed so that the user can view it again later or again. However, even if the recording capacity of the recording medium is increased and a large amount of content can be recorded using the image compression technology, even if a large amount of content can be recorded, When various contents are recorded, it is not easy to find a desired content from among them.

  On the other hand, even in such a case, a technique has been proposed in which a desired content can be easily found (see, for example, Patent Document 1).

In the technique described in Patent Document 1, each content is represented by an icon, and each icon is arranged and displayed in a three-dimensional manner, and the three-dimensional space is divided according to a genre. The icons are displayed on the screen by dividing them into spaces of genres to which the contents correspond.
JP 2006-217627 A

  By the way, in the technique described in the above-mentioned Patent Document 1, the icons of the respective contents are displayed by being divided into areas corresponding to the genres of these contents. In addition, since all the contents are classified into the corresponding genres, when searching for the latest contents, it is necessary to make a judgment by looking at the contents of the icons displayed in all the areas, which takes time and effort for that. .

  In addition, since each area is also provided adjacent to each other at the boundary, even if the icon is divided for each area, even if the genre of the content is different, the icons of different genres are displayed in close proximity. As a result, it takes time and effort to recognize the difference between genres.

  The object of the present invention is to solve such problems and easily recognize differences between old and new contents and differences in keywords so that desired contents can be found easily, accurately and quickly. An object is to provide an information display device.

  To achieve the above object, the present invention provides a content receiving means, a display means for displaying the content received by the receiving means, and a keyword related to the content for the content received by the receiving means. In a content display device comprising means for creating and storing in the memory as bookmark information associated with the content, the display means uses the content with the latest date and time when the bookmark information is created as the representative content, and the representative content The keyword axis extending from the icon is displayed for each keyword of the representative content centered on the icon of the representative content, and the icon of the content other than the representative content corresponds to the keyword with the maximum weight of the content On the keyword axis, the date and time when the bookmark information was created It is characterized in that the display arranged in Shii order.

  Further, the present invention is characterized in that the displayed keyword axis is for a number of keywords set in descending order of weight among the keywords of the representative content.

  In the present invention, the total number of icons along the keyword axis is a set number, and the keyword axis corresponding to the keyword having the largest weight among the keywords created in the content The icon is displayed on the screen.

  Further, the present invention provides means for enabling the icon displayed at the center of the display means to be changed to an icon of any one of the contents on which the icon is displayed along the keyword axis. It is characterized by that.

  Further, the present invention is characterized in that means for changing the number of the contents on which the icon is displayed along the keyword axis is provided.

  In addition, according to the present invention, when the number of contents for displaying an icon on the display screen is set to one, the icon is displayed at the center of the display screen together with the keyword of the content corresponding to the icon. It is characterized by doing.

  Further, the present invention is characterized in that means for changing the number of displayed keyword axes is provided.

  Further, the present invention is characterized in that there is provided means for selecting a display mode for displaying a set number of the content icons along the time axis.

  Further, the present invention is characterized in that there is provided means for selecting a display mode for displaying on the map a predetermined number of icons of the contents in the order of newest creation date and time of the bookmark information. .

  According to the present invention, since each content is clearly divided into keywords and displayed in association with each other in the newest order, the desired content can be easily and accurately found quickly.

  In addition, according to the present invention, since the form of content division can be selected, the user can search for the content in the form of easy-to-recognize the division (display mode), and the desired content can be easily and accurately and quickly. It becomes possible to find out.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram schematically showing a configuration of an embodiment of a content information display device according to the present invention. 1 is a content information display device of this embodiment, 2 is an input unit, 3 is a display unit, 4 is A storage unit, 5 is a CPU (Central Processing Unit), 6 is a GPS (Grobal Positionig System) unit, 7 is a communication unit, and 8 is a tuner.

  In the figure, a content information display device 1 includes an input unit 2 for inputting an operation signal by operating an operation button such as a bookmark button 9 of an operation unit (not shown), a program being received, and a recorded program to be reproduced. Display unit 3 for displaying contents such as content and images for program search, information related to map information, keywords related to the contents of contents to be described later, titles and channel names of received programs and recorded programs (hereinafter referred to as attribute information) ), A memory for storing bookmark information of contents which have been performed by a bookmark button 9 described later, a clock section 5 for providing time information representing the current date and time, and position information representing the current position of the content information display device. GPS unit 6, communication unit 7 for communicating with an external mechanism unit via a network (not shown), tuner 8 for receiving a broadcast program, and this Controls al, also includes a CPU10 that performs various processes for the image display Do. Note that a memory for recording and reproducing a received program may be provided, and the GP unit 6 is used for an in-vehicle TV receiver, a portable device, and the like, and is installed and used. This is not always necessary for a receiver or a PC.

  The bookmark button 9 is used to specify and store the content displayed on the display unit 3 (broadcast program, recorded program to be reproduced, etc.) that the user likes, By operating the bookmark button 9, the CPU 10 reads information related to the content from the memory 4, creates bookmark information, and stores it in the memory 4. In this case, a program for which bookmark information is created in this way is such that when a certain amount of time has elapsed on the display unit 3 and the user wants to view it again later, the bookmark button 9 is operated. Thus, bookmark information is created at this point.

  Using this bookmark information, a program search screen is created and displayed, as will be described later, whereby a desired program can be searched. The searched program can be acquired from the outside via the communication unit 7 by using the corresponding bookmark information, and can be displayed on the display unit 3. When the bookmark button 9 is operated, the program to be displayed has a certain amount of time, and if this is recorded, it will be recorded from the middle. However, according to such a method, by forming a server that can provide a program that has already been broadcast, it is possible to acquire the content from this server by sending bookmark information of the searched program to this server.

  The keywords include seasons such as “Autumn” and “Spring”, those representing places such as “Kyoto” and “Hokkaido”, those representing preferences such as “gourmet” and “hot springs” There are things representing events such as “Travel”, “Tour”, “Athletic meet”, etc., and a keyword when the bookmark button 9 is operated is set in the content. The keywords are not limited to these. For example, “person”, “vehicle”, and the like can be used as other keywords. The number of keywords set in the content may be two or more, and when the number is two or more, these keywords are weighted. For example, in the case of content related to an autumn tour, the keywords “autumn” and “tour” are set, but the content of the display screen when the bookmark button 9 is operated is more If there is a weight in the tour, the keyword “tour” is weighted more than the keyword “autumn”.

  The keyword is, for example, provided from a provider (for example, a broadcasting station) together with the content when the content is broadcast, or provided in advance from the provider. If the content changes with the passage of time, the weight of the keyword provided changes accordingly. The tuner 8 receives the keyword as well as the content, but when the keyword changed from the provider due to the change is transmitted, the keyword is received and stored in the memory 4.

  Alternatively, such a keyword may be stored in the server, and when the bookmark button is operated, the keyword of the content being viewed at that time may be acquired from this server. The keyword provided at this time is weighted according to the current scene of this content.

  FIG. 2 is a diagram schematically showing a list of bookmark information of contents A, B, C,... Formed using such keywords, and a bookmark button 9 obtained from the clock unit 5 is created. It is composed of time information indicating the date and time, and position information indicating a location such as a scene in the content, and other keywords based on information described later. No. 1 in the descending order of weighting. 2, no. 3 ...

  Here, the contents to which the bookmark information is attached by operating the bookmark button 9 in this way are set in the order of the date and time (date and time represented by the time information) to which the bookmark information is attached. In FIG. 2, the content A has the earliest ranking (the content A is hereinafter referred to as representative content), and the ranking is lowered in the order of the contents B, C, D,. For content A, no. 1 keywords “A” and No. 1 2 keyword “I”, No. No. 3 keyword “U” is set, and for content B, no. 1 keywords “A” and No. 1 2 keyword “I”, No. No. 4 keyword “ka”, no. No. 5 keyword “ki” is set, and for content C, no. 1 keywords “A” and No. 1 2 keyword “I”, No. No. 6 keyword “sa”, no. No. 7 keyword “shi” is set, and for content D, no. 2 keyword “I” and No. 8 keyword “ta”, no. It is assumed that nine keywords “chi” are set.

  Note that the bookmark information is stored and saved in the memory 4, but may be sent to the server and saved, and read from the server when necessary for creating and displaying a search screen, which will be described later. However, in the following description, it is assumed that bookmark information is stored and saved in the memory 4.

  The content with the bookmark information can be searched using the bookmark information when viewed again. Hereinafter, screen display for searching for such content will be described.

  FIG. 3 is a flowchart showing a series of operations for displaying the search screen. The operation will be described below with reference to FIG.

  When an operation for displaying a search screen is performed by the operation unit while an image is displayed on the display unit 3, as shown in FIG. 4, a menu screen is displayed at a predetermined position on the video screen of the program (here, the upper right part). 13 is displayed, and the operation for displaying the search screen is started (step 100). On this menu screen 13, typical metadata 11 of the content and a set keyword list 12 are displayed. The content for which the metadata is displayed is the content for which the latest bookmark information among the bookmark information stored in the memory 4 is created, and is content A in FIG. This content A is hereinafter referred to as the title “Kyoto Autumn Tour” as shown in FIG. The tile keywords set in the bookmark information are “autumn”, “travel”, “gourmet”, “Kyoto”, and “tour” in the order of weighting.

  When the content of the menu screen 13 is confirmed and the menu button is turned on by the operation unit (“Yes” in step 101), the initial screen of the content information display screen shown in FIG. 102).

  FIG. 5 is a diagram showing a specific example of the initial content information display screen displayed in step 102 of FIG. 3, wherein 14a is the content information display screen, 15a to 15e are the keyword axes, and 16 is the content display number setting. , 17 is a keyword reference display button, 18 is a time order reference display button, 19 is a position reference display button, 20 is a new addition button, and 21 is a keyword axis setting screen.

  The content information display screen 14a, which is the initial screen that is displayed first, is obtained by dividing the content with respect to keywords (keyword reference display mode) as shown in FIG. On the content information display screen 14a, buttons for setting each display mode, that is, a keyword criterion display button 17 for selecting a keyword criterion display mode, and a time axis criterion display button for selecting a time order criterion display mode. 18 and a position reference display button 19 for selecting a position reference display mode are provided. This keyword reference display mode is set by selecting the keyword reference display button 17, but the display state shown in FIG. The initial screen of the content information display screen 14a shown in FIG. 5 is in the keyword criterion display mode in which the keyword criterion display button 17 is selected as a default.

  A new addition button 20 for newly adding an object, a keyword axis, and the like, and a content number setting button 16 for designating the number of contents to be displayed are also provided.

  Further, the content number setting button 16 described above, a keyword reference display button 17 for selecting a display mode, a time axis reference display button 18, a position reference display button 19, and a new object (such as a keyword axis) are added to the display. The new addition button 20 for displaying is displayed on any of the content information display screens to be described later, and can be operated to change the display state.

  In the keyword reference display mode, an icon of content A (content of the title “Kyoto Autumn Tour”) is displayed at the central position P of the screen 14a, and the representative content A is set from the position of the representative content A. The keyword axes 15 a, 15 b, 15 c, 15 d, and 15 e are extended, and the content in which the keyword is set for each keyword axis is displayed as an icon.

  Here, the correspondence between the keyword / content in FIG. 5 and the keyword / content shown in FIG. 2 is as follows.

  That is, the contents A, B, C, and D in FIG. 5 correspond to the contents A, B, C, and D in FIG. 2, and the contents E in FIG. 5 are omitted in FIG. Further, the keyword axis 15a of the keyword “autumn” in FIG. 5 corresponds to the keyword “a” in FIG. 2, and the keyword axis 15b of the keyword “Kyoto” is the keyword “I” and the keyword axis of the keyword “gourmet”. 15c corresponds to the keyword “u”, the keyword axis 15d of the keyword “journey” corresponds to the keyword “u”, and the keyword axis 15e of the keyword “tour” corresponds to the keyword “e” (not shown). Accordingly, the contents B and C are set on the keyword axis 15a as shown in FIG. 2, the contents D is set on the keyword axis 15b, and the contents E is set on the keyword axis 15c.

  The number of contents displayed on the content information display screen 14a is set by the content display number setting unit 16 in the order of the date and time when bookmark information is set, but changes according to the operation of the operation unit. be able to. In this example, “5” is set, and accordingly, the five content items A to E are set to the corresponding keyword axes 15a to 15c in the order of the date and time when the bookmark information is set.

  FIG. 6 is a flowchart showing the flow of display processing of the content information display screen 14a in step 102 of FIG.

  FIG. 7 is a diagram showing the processing of each step of FIG. Here, the three keywords will be described with reference to FIG.

  In FIG. 6, when the menu button is turned on on the operation unit, the latest bookmark information of the representative content A is extracted from the risk of the bookmark information stored in the memory 4 (step 110). As shown, the icon A is positioned at the center P of the screen (step 111 in FIG. 6). Then, from the bookmark information of the representative content A, based on the keywords “A”, “I”, “U” of the representative content A, in the order of the weights, as shown in FIG. The keyword axes “A”, “I”, “U” extending from the representative content A are set (step 112 in FIG. 6), and bookmark information is provided for each keyword axis “A”, “I”, “U”. The contents are set on the corresponding keyword axis in the new order in which are created (step 113 in FIG. 6).

  That is, according to FIG. 2, the new content B next to the representative content A is set on the keyword axis, but is set on the keyword axis corresponding to the keyword with the largest weight. In this content B, keywords “a”, “i”, “ka”, etc. are set, and among them, the keyword “a” is weighted the most, so as shown in FIG. The content B icon is set to “A”. For the keyword “I”, since an icon is set on the keyword axis “A” for the content B, the icon for the content B is not set. That is, in each content, an icon is set only on the keyword axis corresponding to the keyword with the maximum weight among the corresponding keyword axes.

  Similarly, as shown in FIG. 7D, the icon of the content C is set to the keyword axis “A”. The content D does not have the keywords “A”, “I”, “U”, and the keyword axes to be set are only the keyword axes “A”, “I”, “U”. As shown in e), it is ignored and is not displayed on the content information display screen 14.

  In FIG. 6, this process is repeated until the number of contents displayed on the content information display screen 14a reaches the number set by the content display number setting unit 16 (5) (step 114). The process of step 102 in FIG. 3 is completed, and the content information display screen 14a shown in FIG. 5 is completed and displayed.

  Next, when a content icon other than the representative content A among the displayed contents is selected as shown in FIG. 5 (step 103: this selection is performed by a click operation of a cursor (not shown). When a content is selected by clicking, the selected content moves to a screen where the selected content is displayed on the display screen), and a similar content information display screen in which the selected content is arranged at the central point is formed. Is displayed (step 104).

  FIG. 8 is a diagram showing the relationship between the display contents on the content information display screen 14 formed by the process shown in FIG. 7 and the bookmark information shown in FIG.

  In the figure, the keywords enclosed in a triangle frame are keywords set as the keyword axis. Here, it is assumed that the keywords “A”, “I”, “U” for the representative content A are set as the keyword axes. Show. The content having the keyword for which such a keyword axis is set (in this case, representative content A) is set at the center of the content information display screen 14a.

  ○ Keywords surrounded by a frame are keywords whose contents are displayed on the corresponding keyword axis. Here, the contents B and C are displayed on the keyword axis “A”, and the content D is displayed on the keyword axis “I”. It is shown that.

  The keywords enclosed in the pentagonal frame are different from the keyword axis keywords set in the content information display screen 14a, and indicate that no content is displayed on the keyword axis.

  From the above, the representative content A is displayed in the center of the content information display screen, and the keyword axes “A”, “I”, “U” are extended from now on, and the contents B and C are displayed on the keyword axis. However, it is not displayed on the keyword axes “I” and “U”, and the content D is not displayed on the keyword axes “A” and “U”, but is displayed on the keyword axis “I”. .

  FIG. 9 is a flowchart showing the flow of display processing of the content information display screen 14 in step 104 of FIG.

  In FIG. 9, when an icon of a content other than the representative content A, for example, content B, is click-selected on the content information display screen 14a shown in FIG. 5 (step 120), the risk of bookmark information stored in the memory 4 increases. The bookmark information of the selected content B is extracted, and the icon B is set at the center of the screen as in FIG. 7A (step 121). Then, from the bookmark information of this content B, based on the keywords “a”, “ka”, “ki” of this content B, in the order of the weighting, the content for each of these keywords is the same as in FIG. The keyword axes “A”, “I”, “KA”, “KI” extending from B are set (step 122), and the keyword axes “A”, “A”, “D” are set in the same manner as in FIGS. For each “I”, “ka”, and “ki”, the contents are set on the corresponding keyword axis in the order of representative contents A, C,... In the order in which the bookmark information is created (step 123). In this way, the designated number of contents are displayed on the corresponding keyword axis (step 114), and the process of step 104 in FIG. 3 is completed.

  In FIG. 3, on the content information display screen 14a as shown in FIG. 5, as described above, the content display number setting unit 16 is selected with the cursor and the operation of changing the number of contents to be displayed is performed (step 105) The number of contents displayed on the content information display screen 14 is changed (step 106).

  FIG. 10 is a diagram showing a specific example of a content information display screen when an instruction is given to add the number of contents to be displayed. Here, the content display number setting unit 16 of the content information display screen 14a shown in FIG. For example, “10” is designated.

  In this way, when the number of contents to be displayed is increased, in FIG. 5, the displayed content axis is selected from the contents in which bookmark information is created next to the contents A to E displayed so far. The contents having the contents of 15a to 15e with a large weighting are searched from the bookmark information list, and when this is present, an icon is displayed on the keyword axis corresponding to the keyword. The content information display screen 14b shown in FIG. 10 shows a state in which the contents F to J indicate 10 contents added to the respective keyword axes 15b, 15d, and 15e.

  Further, in the content information selection screen such as the content information selection screen 14a shown in FIG. 5, if the number in the content number setting unit 16 is reduced, the number of displayed contents is reduced, but this number is designated as one. In this case, only the latest representative content A icon displayed in the center of the display screen is displayed. However, in this case, as shown in FIG. 11, the specific keyword display screen 22 on which the icon 23 of the representative content A and the menu screen 13 that are enlarged almost on the entire screen are displayed.

  As shown in FIG. 11, when the icon of the representative content is displayed in an enlarged manner, an image of the representative content may be displayed instead of the icon.

  This specific keyword display screen 22 is also provided with a content display number setting unit 16, a keyword reference display button 17, a time order reference display button 18, a position reference display button 19, and a new addition button 20, which can be operated. When the number of contents to be displayed by operating the display number setting unit 16 is set to the original five, for example, the display returns to the original content information display screen 14a shown in FIG.

  In the content information display screen such as the content information display screen 14a shown in FIG. 5, when the content other than the representative content A displayed in the central portion, for example, the content B is displayed as shown in FIG. As described above, by selecting and clicking the icon of the content B with the cursor, the content B is displayed on the central portion P of the content information display screen 14a. The set number may be set to one.

  In the content information display screen 14a shown in FIG. 5, a keyword axis setting screen 21 is displayed in the vicinity of the icon of the latest representative content A displayed at the center thereof, and this constitutes the keyword axis. Keywords are displayed so as to be selectable by operating a cursor (not shown). Here, all of the keywords “autumn”, “Kyoto”, “gourmet”, “travel”, and “tour” are selected, and therefore, these keyword axes 15a to 15e are set.

  Here, when one of the keyword axes 15a to 15e, for example, the keyword, the keyword axis 15e of “journey” and “tour” is unnecessary, the keyword “tour” is selected by operating the cursor on the keyword axis setting screen 21. 12 is displayed, the content information display screen 14c from which the keyword axis 15d of the keyword “journey” and the keyword axis 15e of the keyword “tour” are deleted is displayed.

  When a keyword axis is added on the content information display screen 14c shown in FIG. 12, a new object addition window 24 is opened on the content information display screen 14c by operating the new addition button 20, and an object to be added thereto For example, the keywords “tour” and “journey” can be written (input). Then, by writing this keyword and operating the “OK” button 25, the keyword axes 15e and 15d of these keywords “tour” and “journey” as shown in FIG. 5 are added, and the contents of the keyword corresponding to this are added. Is displayed (in FIG. 5, such content is not displayed), the content information display screen 14a is displayed.

  When the “cancel” button 26 is operated, the input keyword is deleted.

  As described above, it is possible to search for the content for the required keyword except for the unnecessary keyword axis, and if the required keyword axis is insufficient, add it. The content can be searched for a necessary keyword.

  By the way, in the content information display screen 14a shown in FIG. 5, for example, the keyword axis 15e for the keyword “tour” is provided, but the content is not displayed because the number of contents to be displayed is limited. . For such a content axis 15e, in order to perform content related thereto, only the keyword “tour” on the keyword axis 15e has to be selected on the keyword axis setting screen 21.

  FIG. 14 is a diagram showing a specific example of the content information display screen in this case. 14d is a content information display screen, 27 is a keyword, and parts corresponding to the previous drawings are denoted by the same reference numerals and overlapped. Description is omitted.

  In this figure, on the content information display screen 14d, only the keyword axis 15e of the keyword “tour” is displayed, and the contents having the keyword “tour” are displayed in order from the left in the order of new bookmark information. The In each content, the keywords set in the content are displayed in the order of weighting.

  In this way, content having a keyword on the keyword axis is arranged and displayed on the keyword axis on which the content of a plurality of displayed keyword axes is not displayed, so that the content can be known. .

  Returning to FIG. 3, when the time axis reference display button 18 or the position reference display button 19 is operated and another display mode is selected on the content information display screen 15 (14a to 14d) shown in FIG. (Step 107) Display is performed in the selected display mode (Step 108). Then, the set display mode is performed until the display is turned off (step 109).

  Next, display modes other than the keyword criterion display mode selected in step 107 will be described.

  For example, when the “time order” reference display button 18 is operated on the content information display screen 14a shown in FIG. 5 (which may be another content information display screen), for example, as shown in FIG. A time order display mode in which the window of the “time order” reference display screen 28 is opened on the screen 14a is set. On this “time order” reference display screen 28, a time axis 29 is displayed, and the content with the newest setting date and time of bookmark information is arranged on the right side along the time axis 29, and the icons of the contents are set in order of the newest setting date and time. Are arranged and displayed. In addition, the icons of each content are displayed with the metadata 31 and the keywords 30 of each content in the order of the weighting.

  The “time order” reference display screen 28 displays the contents in the order of date and time when the bookmark information is created from the list of bookmark information shown in FIG. 2 stored in the memory 4 (FIG. 1) by the CPU 10 (FIG. 1). Are read (ie, read in the order in this list), processed and created.

  As a result, it is possible to check new contents without being bound by keywords.

  Further, for example, when the “position” reference display button 19 is operated on the content information display screen 14a shown in FIG. 5 (may be another content information display screen), for example, as shown in FIG. A position display mode in which the window of the “position” reference display screen 32 is opened on the display screen 14a is set. On this “position” reference display screen 32, a map 33 is displayed, and the number (in this case, five) of the number set by the content display number setting unit 16 in the order of the most recent setting date and time of bookmark information on this map 33 is displayed. Contents A to E are displayed.

  Here, the displayed map 33 displays an area including a place in a scene viewed on the date and time when the bookmark information of the displayed contents A to E is created. The location is obtained from the keyword “position” of the bookmark information shown in FIG. 2, and the map 33 is obtained from the map information stored in the memory 4 (FIG. 1).

  The map 33 may include all the locations of the displayed contents A to E (thus, if such locations are scattered all over Japan, a map of Japan will be used). You may make it display a different map for every.

  In this way, it is possible to know where the scene of each content belongs, and it is also possible to obtain content having a scene at a location desired by the user.
