  The screen generation unit 109 also generates information for displaying another screen related to the content selected on the content list screen on the display device 170.

  As an example, a case will be described in which a recording reception screen 15, which is a separate screen, is displayed in order to receive a recording operation from the program display screen 13. As shown in FIG. 5, when the content 400 is selected on the program display screen 13 and the “record” button of the operation device is further operated or “record” 23 c of the selection menu 20 c is selected, The screen generation unit 109 generates information that allows the recording reception screen 15 for performing operations related to recording of the content 400 to be displayed on the display device 170 under the control of the display control unit 106 described later. As shown in FIG. 6, the recording acceptance screen 15 shows the title, channel, broadcast date and time of the selected content 400, and the recording of the content 400 is accepted by operating the recording button 23e. When it is completed, a message such as “Recording reservation accepted” is displayed. The selection menu 20c further includes a “similar content search” 21e as a menu.

  As another example, a detailed display screen 14 that is a separate screen is displayed from the above-described list display screen 11 (see FIG. 3), search screen 12 (see FIG. 4), and program display screen 13 (see FIG. 5). The case will be described. Selection menus 20a, 20b, and 20c on the list display screen 11 (see FIG. 3), the search screen 12 (see FIG. 4), and the program display screen 13 (see FIG. 5) (hereinafter referred to as the selection menu 20 unless otherwise specified). ) Are provided with “detailed display” menus 22a, 22b, and 22c (hereinafter referred to as “detailed display” menu 22 unless otherwise specified). Then, when the “detail display” menu 22 is selected by operating the operation device, the detail display screen 14 shown in FIG. 7 is displayed on the display device 170 by the display control unit 106 described later. Alternatively, the “detail display” button may be provided in the operating device, and the detail display screen 14 may be displayed on the display device 170 by operating this button.

  Here, as shown in FIG. 7, the detailed display screen 14 displays detailed information related to the content such as the title and channel of the content, broadcast date and time, performers, program contents, and genre. The detail display screen 14 includes menus such as “return” for displaying the previous screen, “playback” for reproducing the content, and “recording” according to the state of the content. Further, the detailed display screen 14 includes a “similar content search” 21d as a menu for starting a search for related content using the displayed content as key content.

  The selection unit 101 functions as a selection unit, recognizes that the operating device has been operated, and selects key content that is content to be a search key in response to a selection operation on the content list screen. The selection unit 101 recognizes that the operating device has been operated, and accepts the operation. Here, examples of the operation device include a remote controller 90 provided with operation buttons, a keyboard (not shown), a mouse, and the like. The operation on the remote controller 90 is pressing of the operation button. This is a key operation, and an operation with a mouse is a movement of the mouse or a press of an operation button.

  Specifically, the selection unit 101 selects key content in response to a selection operation on the list display screen 11 that displays the content and other files displayed on the display device 170 as a list. That is, on the list display screen 11 shown in FIG. 3, the “determine” button or “search start” button of the operating device is further operated while the cursor is moved by the operation of the operating device and the content 400 is selected. Then, the selection unit 101 selects the content 400 as content (key content) serving as a search center (key). Alternatively, when the cursor 400 is moved by the operation of the operation device and the content 400 is selected, and the “similar content search” is selected from the selection menu 20a by the operation of the operation device, the selection unit 101 selects the content. 400 is selected as the key content.

  In addition, the selection unit 101 selects key content in response to a selection operation on the search screen 12 displayed on the display device 170 and displaying a list of results of the user searching for content and other files. In other words, as shown in FIG. 4, when the cursor is moved by the operation of the operating device and the content 400 is selected, and the “OK” button or the “search start” button of the operating device is further operated, the selection is performed. Unit 101 selects content 400 as the key content. Alternatively, when “similar content search” is selected from the selection menu 20b by the operation of the operating device, the selection unit 101 selects the content 400 as the key content.

  In addition, the selection unit 101 selects key content in response to a selection operation on the program display screen 13 displayed on the display device 170. That is, as shown in FIG. 5, when the cursor is moved by the operation of the operation device and the content 400 is selected, and the “Enter” button or “Search start” button of the operation device is further operated, the selection is performed. Unit 101 selects content 400 as the key content. Alternatively, when “similar content search” is selected from the selection menu 20c by the operation of the operation device, the selection unit 101 selects the content 400 as the key content.

  In addition, the selection unit 101 selects key content in response to a selection operation on the recording reception screen 15 that is displayed on the display device 170 and receives an operation related to content recording. That is, when “similar content search” 21e is selected from the selection menu 20c regardless of before or after recording reception, the selection unit 101 selects content that is being recorded as key content.

  In the recording reception screen 15, for example, when the recording reservation time is continuously set to “19: 00 to 21:00” and the recording operation of a plurality of contents is performed at one time, the selection unit 101 performs the recording operation. Of the plurality of contents, the content with the longest recording time may be selected as the key content, the content that starts broadcasting first may be selected as the key content, and the content that ends broadcasting ends. It may be selected as key content.

  Furthermore, the selection unit 101 selects key content in response to a selection operation on the detailed display screen 14 that displays the detailed information of the content displayed on the display device 170. That is, as illustrated in FIG. 7, when “similar content search” 21 d is selected on the detail display screen 14, the selection unit 101 selects the content that is displayed in detail as the key content. Note that the content displayed in detail may be selected as the key content by operating the “decision” button or “search start” button of the operating device while the detail display screen 14 is displayed. .

  Note that the selection unit 101 may select the content being played back as the key content. In this case, the selection unit 101 may be operated by, for example, operating the “start search” button of the operating device while the content is being played back. 101 selects the content being reproduced as key content.

  Although the details will be described later, the selection unit 101 selects a key content in response to a selection operation for list information on which display information of a plurality of contents displayed on the display device 170 is displayed.

  Note that, in the above description, the selection operation accepting unit 101 displays the “400” of the operation device with the content 400 selected on the list display screen 11, the search screen 12, the program display screen 13, the detail display screen 14, and the recording acceptance screen 15. The key content is selected by operating the “OK” button or the “search” button or by selecting “similar content search” from the selection menu 20a. However, the present invention is not limited to this. As another example, the selection operation accepting unit 101 further includes the mouse 400 in a state where the content 400 is selected on the list display screen 11, the search screen 12, the program display screen 13, the detail display screen 14, and the recording acceptance screen 15. A context menu (right-click menu) 40 as shown in FIG. 8 is displayed by right-clicking or operating the menu display button of the remote controller 90, and “similar content search” 21f is selected from this context menu 40. Thus, the key content may be selected. In the context menu, the content presented as the menu changes depending on the situation.

  When the selection unit 101 selects key content, the metadata acquisition unit 103 acquires metadata of all content (content other than key content and key content). Further, the metadata acquisition unit 103 acquires metadata for the screen generation unit 109 to create a display screen for the list display screen 11, the search screen 12, the program display screen 13, the detail display screen 14, and the recording reception screen 15. . Specifically, for example, the metadata acquisition unit 103 acquires content metadata from the recorded program storage unit 160. Further, the metadata acquisition unit 103 acquires metadata of other files from the data storage unit 190. In addition, the metadata acquisition unit 103 requests content metadata from the IPTV server 200 and acquires the metadata. Furthermore, the metadata acquisition unit 103 acquires content metadata from the electronic program guide stored in the electronic program guide storage unit 150.

  When the selection unit 101 selects key content, the metadata search unit 102 searches the metadata of the key content from the metadata of the content acquired by the metadata acquisition unit 103, and the metadata of the searched key content Is sent to the relevance calculation unit 104. Further, the metadata search unit 102 searches the metadata of the key content acquired by the metadata acquisition unit 103 for metadata of other content for which the relevance calculation unit 104 calculates the relevance with the key content. Then, the metadata of the other searched content is transmitted to the relevance calculation unit 104.

  Further, when the selection unit 101 selects the key content, the metadata search unit 102 sends the metadata of all the content acquired by the metadata acquisition unit 103 to the display information generation unit 105.

  The relevance calculation unit 104 functions as a relevance calculation unit, and based on the selected key content metadata and other content metadata sent from the metadata search unit 102, The degree of relevance of each content is calculated for each item included in the metadata, for example, for each title and channel. Specifically, the relevance RM is calculated using the following formula (1).

  In the above formula (1), N means the total number of metadata that can be acquired by the metadata acquisition unit 103. Further, the metadata M11 (n) corresponding to the key content and “(n)” of the metadata M21 (n) corresponding to any other content are the n-th metadata acquired by the metadata acquisition unit 103. Means data. Also, fan (M11 (n), M21 (n)) is a function that returns the degree of association between the metadata M11 (n) and M21 (n) as RMn, and Wan is a value indicating a weight (n = 1, ..., N).

  The information acquired as metadata here is diverse as described above, but in order to simplify the description, the metadata is {collection date / time, content title, channel, genre, performer list}. (N = 5), and these five metadata are assumed to be n = 1, 2,...

Then, the relevance level RM of the other content with respect to the key content can be expressed as a weighted linear sum of the following 5 relevance levels RM1 to RM5.
RM1 = fa1 (recording date and time of metadata M11, recording date and time of metadata M21)
RM2 = fa2 (title of metadata M11, title of metadata M21)
RM3 = fa3 (channel of metadata M11, channel of metadata M21)
RM4 = fa4 (genre of metadata M11, genre of metadata M21)
RM5 = fa5 (performer list of metadata M11, performer list of metadata M21)

  For example, fa1 is a function that takes a larger value as the recording date is closer and takes a smaller value as the recording date is farther. Specifically, for example, a relational expression such as MO1 / | rec_data (M11) −rec_data (M21) | can be used. Here, rec_data (x) is a function for converting the recording date and time of x into a unique integer, and is a function for converting a certain reference date and time to 0 and converting it to an integer such as the number of elapsed seconds. MO1 is an arbitrary constant, and | X | is a function indicating the magnitude of X, typically an absolute value.

  Here, an example using g which is a function of g (x) = MO1 / | X | is shown when fa1 (M11, M21) = g (rec_data (M11) −rec_data (M21)). However, the present invention is not limited to this. For example, g using the L2 norm, such as g (x) = MO1 / || x || may be used. In this case, || x || is obtained by taking the square root of the sum of squares of the differences between the elements constituting x.

  For g (x), a sigmoid function or the like may be used, or a gamma function or the like may be used. In addition, although the example which takes a big value when the metadata M11 and M21 were near was shown above, it is not limited to this. Conversely, it may be configured to take a small value. It is also possible to use a function g that takes a large value under specific conditions.

  For example, fa2 is realized by a function that takes a larger value as the same number of character strings are included in the title character strings of the metadata M11 and M21. For example, if the title of M11 is “Aiueo” and the title of M21 is “Kakiueko”, the two characters “Ue” in between are included in both. On the other hand, in the case of “Aiueo” and “Kakikukeo”, since one character is included in both, the former has a larger fa2 value. Note that when the degree of relevance is determined based on the keywords included in the program content, it can be calculated in the same manner as the title.

  In the above, an example is shown in which the number of characters included in both is simply compared, but the present invention is not limited to this. For example, the condition that the larger number of common characters from the beginning is taken to be a larger value, or even if there is no common character, if it contains the same concept, it is considered common Further, it may be added. As an example of the latter, for example, “baseball” and “baseball” are considered to be similar, and if they are included in each, it is considered that a common character string is included.

  Also, if the main character string is the same and the sub character strings are different, these are often the content of a common series. In such a case, the value of fa2 is increased. It can happen. For example, “Aiueo # 2” and “Aiueo # 3” can be regarded as different times of the same drama content. In such a case, the value of fa2 is doubled. Note that the above description is merely an example, and by using a well-known technique such as fuzzy search or a well-known technique such as search by regular expression, a higher-level comparison than described above is performed. It becomes possible.

  For example, fa3 is a function that takes a large value when the channels of the metadata M11 and M21 are the same. Simply, it can be realized as a function that takes the value MO2 if the channels are the same, and takes the value 0 otherwise. Here, MO2 is an arbitrary constant. Further, in the case of channels of the same series, another value may be taken. For example, in the case of the same affiliated station, a function that returns the value MO3 may be used. In the case of the same series but different broadcasting media, a function that returns MO2 / 4 may be used. In addition, the aspect demonstrated above is an example to the last, and it is possible to use arbitrary functions.

  For example, fa4 is a function that takes a large value when the metadata M11 and M21 have the same genre. For example, if both M11 and M21 are genres of “sports”, the value MO3 is taken, otherwise the value 0 is taken. Further, if M21 is a subgenre of M11, for example, the genre of M11 is “ When the genre of “sports” and M21 is “baseball”, the function may be MO3 / 2. In addition, even if the genre of M11 and the genre of M21 are not directly the same, the genre that is the parent of both is the same. For example, when the genre of M11 is “baseball” and the genre of M21 is “soccer”, both Since the parent genre of “Sports” is the same, it may be a function of taking MO3 / 4. In addition, the aspect demonstrated above is an example to the last, and it is possible to use arbitrary functions.

  fa5 is the same as fa4. For example, if the list of characters in the metadata M11 and M21 is “WW, XX, YY”, “XX, YY, ZZ”, respectively, there are two common characters, so 2 × MO4 is taken. (Here, MO4 is an arbitrary constant value). If there is no common character, a function that takes 0 can be used. In addition, since the characters include groups, when a certain character KK is a member of the group XX, metadata M11 and M21 such as “VV, WW, XX”, “KK, YY, ZZ” are stored. When there was a group XX in M11, that is, this member's KK also appeared, and in M21 the group XX did not appear, but the member KK appeared, so in this case May return MO4 / 2.

  Similarly, when the relationship between the appearance group and the character is defined, for example, when the group XX and the group YY are the same affiliation office, it is extended to return MO4 / 4. It is good. In this case, the relationship between the person and the group or the relationship between the offices to which each person and group belong may be defined in the metadata, or may be acquired from an external server (information site). It is good.

  In addition, although the example which does not distinguish the relevance degree with respect to the person who appears in a character list was shown above, it is not limited to this. It is good also as an aspect weighted further by the order which appears in a character list. For example, in the case of comparison with the first person appearing in the metadata M11, the calculated relevance is left as it is, and the relevance is 1/2 for the second, and 1/3 for the third. It is good also as changing weighting according to the order to do. Moreover, it is good also as an aspect which considers both the order in metadata M11, and the order in M21. For example, when comparing the second person of the metadata M11 with the third person of the metadata M21, the second person of the metadata M11 is 1/2, and the third person of the metadata M21 is 1/3. Therefore, the total relevance may be set to 1/2 × 1/3 = 1/6. Moreover, you may make it change the weighting of the relevance degree with respect to a leading character using information, such as a leading character, as metadata. For example, in the case of a leading role, the weight can be changed so that the calculated degree of relevance is doubled.

  The display information generation unit 105 functions as a display information generation unit. Based on the key content metadata and the other content metadata sent from the metadata search unit 102, the display information generation unit 105 stores the key content and other content. Display information representing the contents is generated. Specifically, for example, the display information generation unit 105 attaches a title or the like to the representative image of the video data based on the metadata of the video data whose content is stored in the recorded program storage unit 160, and displays the display device. Display information that can be displayed in 170 is generated. In addition, for example, the display information generation unit 105 can display the content on the display device 170 by attaching a title or the like to the representative image of the video data based on the metadata of the video data acquired from the IPTV server 200. Generate display information. For example, the display information generation unit 105 can display the TV program title, broadcast date, channel, program content, and the like on the display device 170 based on the electronic program guide stored in the electronic program guide storage unit 150. Generated display information.

  Here, details of the display information will be described. FIGS. 9A and 9B are diagrams illustrating examples of display information representing the content. FIG. 9A is, for example, key content display information C1 generated based on video data metadata stored in the recorded program storage unit 160. As shown in the figure, in the key content display information C1, the representative image of the content is displayed in C1-1, and the title “L358Δ * 6” of the content (video) is displayed in C1-2. Yes. FIG. 9B is display information C1 of key content generated based on, for example, an electronic program guide. As shown in the figure, the display information C1 of the key content is that the channel is displayed in C1-3, the title “Lunch Comedy Show” of the content (video), and the program content “This season to the world” “Nizaina” is displayed, and the broadcast date and time is displayed in C1-5.

  The display control unit 106 reproduces and displays the content transmitted by the video reproduction unit 107 on the display device 170, or displays the list display screen 11, the search screen 12, the program display screen 13, and the detailed display screen generated by the screen generation unit 109. 14. Display screens such as the recording acceptance screen 15 are displayed on the display device 170. Therefore, the screen generation unit 109 and the display control unit 106 function as display means.

  Further, as described above, the display control unit 106, when the selection unit 101 receives a key content selection operation from the user, relates to the key content display information and the key content so that the user can search for the content. Display the list information that lists the display information of other contents that have.

  The list information is arranged on a plurality of polygons concentrically formed with the display information of the key content arranged at a desired position and centered on the position of the display information of the key content. The display information of other contents is arranged in a shape along the operation direction by the operation buttons provided in the above, for example, the operation buttons of the cross key. Further, in the list information, the other content display information is arranged in a predetermined area sorted for each item from the center in the radial direction in descending order of relevance. The list information is displayed with the display size of the display information of the key content being maximized and the display size of the display information of the other content being reduced as the distance from the vicinity of the center is increased. Details of the display information display operation will be described with reference to the drawings. 10A to 14 are explanatory diagrams relating to details of the display information display operation.

  First, as illustrated in FIG. 10A, the display control unit 106 arranges the display information C1 of the key content at a desired position, and the x-axis positive direction, the x-axis negative direction, Four axes (axis 1 to 4) in the positive y-axis direction and the negative y-axis direction are set, and four items included in the metadata of the selected key content are allocated and arranged on each axis. Referring to FIG. 2, for example, as items included in metadata, “title” of a TV program (content), “person” indicating a performer, “keyword” when performing a search included in the program content, TV program The “genre” is assigned to each axis. The item assigned to each axis can be used as an index when the user searches for other content related to the key content.

  Then, as shown in FIG. 10-2, the display control unit 106 radiates from the display information C1 of the key content at the center at an arbitrary angle including each axis indicating each item, for example, 90 degrees including the axis. By separating the areas toward, predetermined display areas (areas 1 to 4) including each axis are generated.

  Next, as shown in FIG. 11, the display control unit 106 has a plurality of octagons F1, F2,... Formed concentrically around the position of the key content display information C1, and Display information of other contents is arranged in a shape along the up / down / left / right operation directions by the provided operation buttons. That is, the display control unit 106 arranges eight pieces of display information from other pieces of display information C11 to C18 at the apex of the octagon F1. In addition, the display control unit 106 arranges eight pieces of display information C21, 23, 25, 27, 29, 31, 33, and 35 of other content at the apex of the octagon F2, and displays each piece of display information. 8, display information C22, 24, 26, 28, 30, 32, 34, 36 of other contents are arranged along the operation direction. Similarly, eight pieces of display information of other contents are arranged at the vertices of an octagon, and display information of other contents is arranged between the pieces of display information. When display information of other contents is arranged in this way, display information other than the display information is arranged along the operation direction regardless of which display information is operated up, down, left, and right.

  At this time, as shown in FIG. 12, the display control unit 106 displays the display information of the other content from the vicinity of the center where the display information C1 of the key content is arranged outward to the degree of relevance with the key content.

That is, as shown in FIG. 11, the display control unit 106 arranges display information of other contents having the highest degree of relevance with the key content on the octagon F1, and further, on F2, F3 (not shown) The display information of other contents is arranged in descending order of relevance.

  In addition, the display control unit 106 arranges display information of other contents in descending order of the degree of association with the key content for each item of the display area that has been sorted first. That is, as shown in FIG. 13, the display control unit 106 displays the area 1 surrounded by the boundary line B1 and the boundary line B4, the area 2 surrounded by the boundary line B1 and the boundary line B2, and the boundary line B2 and the boundary. For each item of the area allocated to the area 3 surrounded by the line B3 and the area 4 surrounded by the boundary line B3 and the boundary line B4, other items are displayed in the numerical order shown in the display information of FIG. By arranging the display information of the content, the display information of other content can be arranged from the vicinity of the center in descending order of the degree of association with the key content for each item.

  The display information C11, 21, 41 is a position that can belong to either the region 1 or the region 2, but has, for example, more other contents whose relevance to the key content is higher than a predetermined threshold. Can be set to belong to an item area. That is, the display information C11, 21 and 41 in FIG. 13 includes more content in the region 2 than the item in the region 1 in the region 2 because the other content having a higher relevance than the predetermined threshold exists. belong to. The same applies to the display information C13, 25, 47, 15, 29, 53, 17, 33, 59.

  Here, the display information displayed in the vicinity of each boundary line is determined to belong to which item area by the high degree of relevance with the key content, but is not limited to this, For example, display information displayed in the vicinity of each boundary line may belong to an item area where the total number of other contents related to the key contents is large.

  Further, as shown in FIG. 14, the display control unit 106 maximizes the display size of the display information of the key content, and displays the display size of the display information of the other content as the distance from the vicinity of the center decreases. In addition, when the display information of other content belongs to a plurality of areas, the display control unit 106 displays the information in any one area. Specifically, when the display information of other content belongs to both the areas 1 and 2, the display control unit 106 displays the information in the area of the item having the highest degree of relevance to the key content.

  In this way, the display control unit 106 generates list information in which the display information C1 of the key content and the display information C11 of other content are arranged, and displays the generated list information on the display device 170. The arrangement position and display size of the display information are stored in advance by the display control unit 106, and after calculating the relevance to the key content, the display information of other content is arranged in order with a predetermined display size. To go. FIG. 15 is a diagram illustrating an example of list information in which display information C1 of key content and display information C11 to other content are arranged.
