In the present embodiment, video recorded from a TV program is used as content.

  The digital television display device 100 shown in FIG. 1 can view content stored in the recorded program storage unit 160 (hereinafter referred to as “PVR content”) based on user operations and the like in addition to the content currently being broadcast.

  In addition, the digital television display device 100 includes as many digital broadcast tuners (not shown) as the number of broadcast stations. Then, the contents are automatically recorded in the recorded program storage unit 160 by these digital broadcast tuners. This automatically recorded content is referred to as automatic recording content. This automatically recorded content is automatically deleted when one week has passed since it was recorded unless the user performs an operation for saving it as PVR content. As a result, the digital television display device 100 according to the present embodiment can view content for one week that has already been broadcast.

  In addition, the digital television display device 100 also holds an electronic program guide for the past week in the electronic program information storage unit 150 (to be described later) in association with holding the automatically recorded content for one week. Thereby, the user can view the content of the past week by selecting it from the electronic program guide (hereinafter referred to as the past electronic program guide).

  In the digital television display device 100 according to the present embodiment, the content currently being broadcast and scheduled to be broadcast, the PVR content, and the automatic recording content are all content.

  The recorded program storage unit 160 is a storage medium such as an HDD or a memory that stores content such as video. The recorded program storage unit 160 stores metadata provided together with the content in association with the content.

  The metadata according to the present embodiment is information (content information) indicating content details. The recorded program storage unit 160 stores metadata for each item for classifying the content. Specifically, the recorded program storage unit 160 stores each content for each item such as the title, channel, broadcast date and time, performer, program content (keyword or text indicating the program content), genre, and the like. Content information to be shown (in other words, content metadata) is stored in association with each other.

  FIG. 2 is an explanatory diagram showing an example of metadata when a TV program is used as content. The metadata shown in FIG. 2 is information related to the content recorded on the TV program. The title of the TV program is “Lunch Comedy Show”, the channel “○ × Broadcast”, and the broadcast date and time “August 1, 2008 12:00:00”. 12:40 ”, performers“ XX, □ xx ”, program content“ this season to the world ”, and genre“ comed ”are stored.

  In the above description, a mode in which metadata is provided in a preset state has been described. However, the present invention is not limited to such a mode. For example, information input from a user via a remote controller (hereinafter also referred to as a remote controller) 90 or an input device such as a PC keyboard may be stored as metadata in the recorded program storage unit 160 in association with content. .

  The electronic program information storage unit 150 is an external server that manages and distributes an electronic program guide (EPG), or a storage medium such as an HDD or a memory that stores an electronic program guide acquired from a TV broadcast. Specifically, an electronic program guide such as TV, CATV, CS broadcast, BS broadcast, etc. is acquired from a server device of a service provider connected to a network such as the Internet, or broadcast by TV broadcast. The received electronic program guide is received via an antenna or a cable (not shown), and the acquired or received electronic program guide is stored. The electronic program information storage unit 150 stores various statuses for each content.

  FIG. 3 is a diagram illustrating an example of a table structure in which the electronic program information storage unit 150 stores electronic program information. As shown in FIG. 3, the electronic program information storage unit 150 stores broadcast date / time, program description, broadcast station name, broadcast time, status, and the like in association with each content (program).

  The program description holds information such as a title, a person, a keyword, and a genre as information (metadata) describing the content. Such information may be information acquired from the Internet or the like in addition to information acquired from the electronic program guide.

  The status holds, for example, information such as broadcasting, reservation setting, recording, reserved recording, archiving, and archiving as information indicating the current status of each content.

  It can be determined in which state each content is in accordance with the presence / absence of “◯” in each status. For example, if “Broadcasting” is “◯”, it means that the content is currently being broadcast. If “reservation setting” is “◯”, it means that the PVR content is held when the content is broadcast. If “Recording” is “◯”, it means that the content is currently being recorded as PVR content.

  Further, if “reserved video recording” is “◯”, it means that the content is held as PVR content. Further, if “in archive” is “◯”, it means that the content is being recorded as automatic recording content. Further, if “archived” is “◯”, it means that the content has been recorded as automatic recording content.

  That is, by referring to the status of the electronic program information storage unit 150, it is possible to specify whether each content is a content being broadcast or scheduled to be broadcast, an automatically recorded content, or a PVR content.

  Then, the metadata acquisition unit 103 acquires the broadcast date and time, the program description, the broadcast station name, and the broadcast time, and the display control unit 106 generates an electronic program guide, various content list screens, and the like based on the information. , Process for display.

  Here, in the electronic program guide, in addition to the list information of programs broadcast from the present to a certain point in the future (for example, one week later), the program is broadcast from the present to a certain point in the past (for example, one week before). Also included is a list information (past electronic program guide) of a program (automatically recorded content). As a result, the user can view the automatically recorded content based on the content selected from the past electronic program guide by referring to the past electronic program guide.

  In addition, the information regarding the program memorize | stored in the electronic program information storage part 150 shall be updated regularly. For example, the setting of each status is updated in accordance with the passage of time or the user's operation, or a record indicating each content is added or deleted.

  A connection I / F (InterFace) 180 is an interface connected to the external recorded program storage unit 161. Thereby, the digital television display device 100 can record content in the external recording program storage unit 161 via the connection I / F (InterFace) 180. Similarly to the recorded program storage unit 160, the externally recorded program storage unit 161 stores metadata provided together with the content in association with the content. Note that the electronic program information related to the content stored in the external recorded program storage unit 161 is stored in the electronic program information storage unit 150 in the same manner as the recorded program storage unit 160.

  The communication unit 190 communicates via a network with various devices that store content, such as other digital television display devices 195. The communication unit 190 transmits / receives content (PVR content, automatic recording content) and the like to / from other devices, as well as metadata of these content, and further, held by the digital television display device 195. You can also send and receive electronic program guides. As a result, even the digital television display device 100 can search, display, and the like for the content and the like held by the other digital television display device 195.

  That is, in the digital television display device 100, not only the content held by the device itself but also the content held by another device without being aware of which device the user stores, Can be used for viewing and searching.

  The display unit 170 is a liquid crystal screen (LCD) that displays characters and images, and displays content such as received TV programs, stored content, electronic program guides, and the like.

  FIG. 4 is a diagram illustrating an example of an electronic program guide displayed on the display unit 170 in which contents currently being broadcast and scheduled to be broadcast are arranged. As shown in FIG. 4, an electronic program guide 402 is displayed in the display screen 401 of the digital television display device 100. The electronic program guide 402 includes a date / time display unit 411 and a broadcast station specific frame 412. In the broadcast station specific frame 412, a thumbnail 413 indicating a broadcast station, a broadcast station display unit 414, and a program column 415 for each broadcast station are displayed. Further, the time display unit 416 displays the time at which each content is provided so as to be visible. Further, a current time bar 417 indicating the current time is displayed.

  Then, as shown in FIG. 4, an operation guide section 403 for operating the electronic program guide and moving to another content list screen is displayed. Each item shown in the operation guide unit 403 corresponds to a color button (not shown) of the remote controller 90. That is, when these buttons are pressed, the operation indicated in each item is performed. For example, when a color button of the remote controller 90 corresponding to the program search 403a is pressed, a program search screen for searching for content currently being broadcast or scheduled to be broadcast is displayed.

  The display unit 170 also displays a past electronic program guide in which automatically recorded content is arranged, a list of PVR content, and the like according to the type of content. The display format may be any format including a conventionally known format.

  FIG. 5 is a diagram showing an example of a screen displayed by the display unit 170 when the button corresponding to the program search 403a is pressed on the display screen of FIG. As shown in FIG. 5, when program search is selected by the user, the display unit 170 displays a window 501. In this window 501, a search navigation 501a and a related program list 501b are displayed so as to be selectable. When the user selects the related program list 501b with the remote controller 90, the digital television display device 100 searches for content related to the content (for example, content 511) selected on the display screen. Done.

  In addition, when the search navigation 501a is selected, the description is omitted on the assumption that the screen is shifted to a search screen that is conventionally used. On the other hand, when the related program list 501b is selected, the display unit 170 displays related content list information.

  In addition, the display unit 170 will be described later with display information (see FIGS. 6A and 6B) representing the content of the content generated by the display information generation unit 105, which will be described later, for the user to search for the content. The related content list screen (see FIG. 8) arranged by the display control unit 106 is displayed. The display unit 170 displays each item in the related content list screen (see FIG. 8).

  The broadcast receiving unit 108 receives video content (TV program) broadcast by TV broadcasting via an antenna or a cable (not shown).

  The video playback unit 107 acquires and acquires video content desired by the user, that is, content such as a TV program received by the broadcast receiving unit 108 or video content stored in the recorded program storage unit 160. The decoded content is decoded (reproduced) and sent to the display control unit 106.

  The operation receiving unit 101 recognizes that the operating device has been operated and receives the operation. Examples of the operation device include a remote controller 90 provided with operation buttons, a keyboard (not shown), a mouse, and the like. An operation on the remote controller 90 is a press of the operation button, and an operation on the keyboard is a key operation. The operation with the mouse is a movement of the mouse or a press of an operation button.

  The operation reception unit 101 receives selection of content (key content) used as a search reference (key). Specifically, the operation accepting unit 101 accepts selection of content belonging to the category currently displayed on the display unit 170 among currently broadcasted content, content scheduled to be broadcast, automatic recording content, and PVR content.

  For example, when a user searches for a desired content from a plurality of contents and further searches for a content related to the content, the search center (key) is selected from the plurality of contents displayed on the electronic program guide displayed on the display unit 170. When the user selects the content (key content) to be used by the operation device, the operation reception unit 101 receives the key content selection operation, specifies it as a search base point (key), and searches the content. The operation of is accepted.

  The key content specifying method is not limited to the selection of the key content by the user, and the key content may be specified on the system side. Further, when the display screen of FIG. 5 moves to the related content list screen, the content 511 selected in FIG. 5 may be used as the key content. Also, the content being played back may be the key content. In this case, when the user operates the operating device during the playback of the content, the operation accepting unit 101 performs a selection operation using the content being played back as the key content. That is, an operation for searching for content is accepted.

  Furthermore, although the details will be described later, the operation accepting unit 101 responds to the display information of the content of interest from the related content list screen (see FIG. 8) on which the display information of the plurality of contents displayed on the display unit 170 is displayed. To accept the focus operation. The related content list screen is a list screen on which other content having a high degree of association with key content is arranged.

  When the operation receiving unit 101 receives a key content selection operation, the metadata acquisition unit 103 acquires metadata of all contents to be displayed (key content and other content other than the key content). Specifically, the metadata acquisition unit 103 acquires content metadata from the recorded program storage unit 160.

  Further, the metadata acquisition unit 103 acquires content metadata from the electronic program guide stored in the electronic program information storage unit 150.

  When the operation receiving unit 101 receives a key content selection operation, the metadata search unit 102 searches the key content metadata from the content metadata acquired by the metadata acquisition unit 103, and searches the key content. Are 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 operation receiving unit 101 receives a key content selection operation, the metadata search unit 102 sends all content metadata acquired by the metadata acquisition unit 103 to the display information generation unit 105.

  Based on the metadata of the key content and the metadata of other content sent from the metadata search unit 102, the relevance calculation unit 104 calculates the relevance of each of the other contents to the key content for each item (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. Further, fa _n (M11 (n), M21 (n)) is a function that returns the relation between metadata M11 (n) M21 (n) and the RM _n, Wa _n denotes a weighting value (n = 1,..., N).

  The information acquired as metadata here is diverse as described above, but in order to simplify the description, the metadata is set of five sets of {recording date and 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 _five relevance levels RM _{1 to} RM 5 shown below.
RM ₁ = fa ₁ (recording date and time of metadata M11, recording date and time of metadata M21)
RM ₂ = fa ₂ (title of metadata M11, title of metadata M21)
RM ₃ = fa ₃ (channel of metadata M11, channel of metadata M21)
RM ₄ = fa ₄ (genre of metadata M11, genre of metadata M21)
RM ₅ = fa ₅ (performer list of metadata M11, performer list of metadata M21)

For example, fa ₁ is a function that takes a larger value as the recording date is closer and takes a smaller value as it is farther away. 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.

In addition, when fa ₁ (M11, M21) = g (rec_data (M11) −rec_data (M21)), an example using g which is a function of g (x) = MO1 / | X | It 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, fa ₂ 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”, the value of fa ₂ is larger in the former because one character is included in both. 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.

If the main character string is the same and the sub character strings are different, these are often the contents of a common series. In such a case, the value of fa ₂ is increased. There is also a possibility. 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 fa ₂ 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, fa ₃ 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, fa ₄ is a function that takes a large value when the genres of the metadata M11 and M21 are the same. 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.

fa ₅ is the same as fa ₄ . 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. Further, since the characters include groups, if 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. In this case, group XX appeared in M11, that is, this member KK also appeared, and group XX did not appear in M21, but member KK appeared. 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 generates display information representing the contents of the key content and the other content based on the metadata of the key content and the metadata of the other content sent from the metadata search unit 102. .

  As a more detailed 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 unit. Display information that can be displayed in 170 is generated. As another example, the display information generation unit 105 displays the TV program title, broadcast date, channel, program content, and the like on the display unit 170 based on the electronic program guide stored in the electronic program information storage unit 150. Generate possible display information.

  Here, details of the display information will be described. FIGS. 6A and 6B are diagrams illustrating examples of display information representing the content. FIG. 6A is, for example, display information C1 of key content generated based on metadata of video data 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. 6B is key content display information C1 generated based on an electronic program guide, for example. 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 sent from the video reproduction unit 107 on the display unit 170. In addition, when the operation receiving unit 101 receives an operation to search for content from the user as described above, the display control unit 106 relates to the display information and key content of the key content for the user to search. Display information of other content having the characteristics as related content list information.

  In the related content list information, the display information of the key content is arranged at a desired position, and the item used for calculating the relevance is provided in an operating device such as the remote controller 90 at a position close to the key content. Arranged in the direction along the operation direction of the operation button, for example, the operation button of the cross key. In the present embodiment, items are assigned for each operation direction (up, down, left, right) of the cross key.

  Further, the related content list information is on a plurality of ellipses or polygons formed concentrically around the position of the display information of the key content in the vicinity of each item, and is provided in an operating device such as the remote controller 90. The display information of other contents related to each item is arranged in a shape along the operation direction of the operation buttons, for example, the operation buttons of the cross key.

  In the related content 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 the degree of relevance for each item from the vicinity of the center. In addition, the related content 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 other content being reduced as the distance from the vicinity of the center is increased. Next, details of display information arrangement and display operation in the related content list information will be described. FIGS. 7A to 8 are schematic diagrams illustrating related content list information.

  First, as shown in FIG. 7A, the display control unit 106 arranges the display information C1 of the key content at a desired position, and in the direction corresponding to the direction instruction by the operating device with the display information C1 of the key content as a center. Four axes (axes 1 to 4) of the x-axis positive direction, the x-axis negative direction, the y-axis positive direction, and the y-axis negative direction are set so as to be along. Further, the display control unit 106 arranges each item on each axis extending in the direction corresponding to the direction instruction by the operating device and at a position close to the key content display information C1. That is, the number of axes and the number of items are equal to the number (four directions) that can be designated by the operation button (cross key) for operating the direction provided in the operation device such as the remote controller 90. Thus, the movement direction according to the axis is assigned to each item. If the operation device such as the remote controller 90 is provided with 8 keys of up / down / left / right / upper right / lower right / upper left / lower left, up to 8 axes can be provided.

  Then, as shown in FIG. 7-2, the display control unit 106 has an arbitrary angle including each axis (axis 1 to 4), for example, 90 degrees including the axis, from the display information C1 of the key content at the center. By separating the areas in the radial direction, a predetermined display area (areas 1 to 4) including each axis is generated in association with each item 1 to 4.

  Next, as shown in FIG. 8, the display control unit 106 is on 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 twelve pieces of display information from other pieces of display information C11 to C22 at the apex of the octagon F1. In addition, the display control unit 106 arranges 20 pieces of display information C31 to C50 of other contents at the vertices of the octagon F2.

  Similarly, display information of a predetermined number of contents is arranged in the up / down / left / right operation directions.

  FIG. 9 is a diagram illustrating an example of content display information that the display control unit 106 arranges for each of the upper, lower, left, and right operation directions. As shown in FIG. 9, when the operation direction is up and down, the display control unit 106 arranges and displays content display information so as to be within the horizontal width 901 of the display area. In this embodiment, seven pieces of content display information are arranged in a horizontal width 901.

  On the other hand, when the operation direction is left and right, the display control unit 106 arranges and displays the display information of the content so as to be within the vertical width 902 of the display area. In this embodiment, the display information of five contents is arranged in the horizontal width 902.

  FIG. 10 is a diagram illustrating lines that serve as a reference when the display control unit 106 arranges display information of content. As illustrated in FIG. 10, the display control unit 106 performs display by arranging display information of other content on the circumference of an ellipse centered on the display information C1 of key content. At this time, as the arrangement of the display information of other contents separated from the center (key contents) by a certain distance or more, the number of contents on each arc is made equal with the same curvature. Furthermore, as shown in FIG. 10, display information of other contents is not arranged in the oblique area.

  More specifically, the display control unit 106 displays the display information of each content after arranging as shown in FIG. That is, display information is arranged so that the content having a high degree of association with each item fits within the horizontal width 901 or vertical width 902 of the display area, and display information is not arranged in the diagonal area.

  By the way, when display information of other contents exists in an oblique area, the user needs to perform an operation in any of the upper, lower, left, and right directions in order to refer to the display information of other contents of each item. there were. For this reason, when performing the said operation with the remote control 90, operation until detecting the desired content was complicated. On the other hand, in the digital television display device 100 according to the present embodiment, when the user wants to refer to content having a high degree of association with each item, the user only needs to perform the operation in the vertical direction or the horizontal direction for each item. . For this reason, even if it is remote control 90, operation becomes easy.

  Also, as shown in FIG. 11, the display control unit 106 has three pieces of display information of other contents as columns 1101, 1102, 1103, and 1104 in the innermost periphery centering on the display information C1 of the key content. Place one by one. Around the outer periphery, five pieces of display information of other contents are arranged as columns 1106, 1107, 1108, and 1109, respectively. Further, seven pieces of display information of other contents are arranged as upper and lower columns 1112 and 1114 on the next outer periphery. Five pieces of display information of other contents are arranged as left and right columns 1111 and 1113, respectively. Thereafter, the arrangement of 7 in the upper and lower rows and 5 in the left and right rows is repeated as described above.

  Furthermore, as shown in FIG. 12, the display control unit 106 displays the display information of other contents for each item from the vicinity of the center where the display information C1 of the key content is arranged to the outside. Arrange them in order of relevance. 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 key contents on the columns 1101, 1102, 1103, and 1104 included in the innermost ellipse. Furthermore, the columns 1106, 1107, 1108, 1109 included in the next outer periphery of the innermost periphery, the columns 1111, 1112, 1113, 1114 included in the next outer periphery, and the relevance in order from the innermost periphery to the outer periphery. The display information of other content with high is arranged.

  Also, the display control unit 106 displays the display information of other contents in the order of the degree of association with the key content related to each item in each display area (area 1, area K1, K2, K3, K4). It arrange | positions to the area | region 2, the area | region 3, and the area | region 4). That is, as shown in FIG. 13, the display control unit 106 assigns the area 1 surrounded by the boundary line B1 and the boundary line B4 to the item K1, and sets the boundary line B1 and the boundary line B2 to the item K2. The area 2 surrounded by the boundary line B2 and the boundary line B3 is allocated to the item K3, and the item K4 is surrounded by the boundary line B3 and the boundary line B4. Assigned to area 4. And the display control part 106 arrange | positions display information so that a gap may be provided between each area | region and the difference of each item may be grasped | ascertained clearly. In each area, the display information of other contents is arranged in the order of the numbers shown on the display information in FIG. 13 in descending order of the degree of association with the key contents regarding each item.

  By the way, basically, humans tend to recognize the left and right scrolls more easily than the up and down scrolls. That is, the display information of the content having a high degree of association with the items K1 and K3 is easier to browse than the display information of the content having a high degree of association with the items K2 and K4. Therefore, the display control unit 106 according to the present embodiment assigns items having higher priority than the items K2 and K4 that move the screen in the vertical direction to the items K1 and K3 that move the screen in the horizontal direction. . That is, the display control unit 106 according to the present embodiment assigns people and genres to the items K1 and K3 as important items that the user refers to better than titles and keywords, and performs display. Thereby, it becomes easy to refer to the display information of the content having a high degree of association with the items K1 and K3 that the user often refers to.

  Further, as shown in FIG. 14, the display control unit 106 maximizes the display size of the key content display information C1, and reduces the display size of the display information of other content as it moves away from the vicinity of the center. 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.

  In this way, the display control unit 106 generates related content 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 related content list information on the display unit 170.

  FIG. 15 is a diagram illustrating an example of related content list information in which display information C1 of key content and display information C11 to other content are arranged. In the related content list information of FIG. 15, items K1, K2, K3, and K4 are displayed at positions close to the key content display information C1. In the example shown in FIG. 15, “person” is assigned to the item K1, “title” is assigned to the item K2, “genre” is assigned to the item K3, and the item A “keyword” is assigned to K4. Then, with the display information C1 of the key content as the center position, the display information of other contents is arranged from the vicinity of the center toward the outside.

  Further, in the present embodiment, display information of other contents is arranged in a shape along the up / down / left / right operation directions. For this reason, when an up / down / left / right operation is received with the display information of each other content, the focused content changes in the arrow direction shown for each display information of each content in FIG. For example, if the focused content is the display information C17 during the search and a right instruction operation is accepted by an operation button or a keyboard key of the remote controller 90, the content is focused on C16, C15, C14, C13, and C41. Content that changes. In addition, when the content of interest during the search is the display information C17, the content focused on C18, C19, and C46 changes when a lower instruction operation is accepted by an operation button or a keyboard key of the remote controller 90.

  For example, when the focused content is the display information C16, when the instruction operation is accepted and the cursor is moved to the right by one cursor, the content focused on the display information C15 is changed. Similarly, the content to be focused changes to display information C39 when the cursor is moved up, to the display information C17 when the cursor is moved to the left, and to the display information C1 when the cursor is moved downward. . This makes it easy to perform an instruction operation from an operation button such as a cross key on the remote controller 90 or a cross key on the keyboard.

  Here, the item selection operation will be described with reference to FIG. First, as described above, the number of axes and the number of items are set equal to the number that can be designated by the cross key of the operating device, and the items K1 to K4 are displayed on each axis as key content display information C1. It is arranged close to. When the cursor is at the position of the key content display information C1, when the cross key of the operating device is operated once in the upward direction, the cursor moves to the content C15 beyond the item K2 “title” arranged above the key content. To move. That is, it is possible to move from the key content display information C1 to other content display information by operating the cross key of the operating device.

  Further, when an operation for focusing the display information of the other content on the outermost periphery is performed (arrows 1501 to 1516), the display control unit 106 according to the present embodiment displays items to which the other focused content belongs. The display mode is switched to the display mode.

  In this manner, the contents belonging to each item assigned to each axis can be selected by the operation keys. The user may be allowed to set items assigned to each axis. In the present embodiment, titles, genres, persons, and keywords are given as examples of items to be assigned, but items such as broadcast stations and broadcast dates may be set. Further, the user may freely arrange his / her favorite items at positions that are easy to see and operate. Thereby, the convenience for each user can be improved.

  Also, in the digital television display device 100 according to the present embodiment, the display control unit 106 displays two types of display modes, the entire display mode and the item display mode, as the display modes when displaying the related content list screen. Exists.

  The whole display mode is a mode in which the display information C1 of the key content is arranged at the center and the display information of the other contents of all items is displayed. The whole display mode is a display mode in which the screen can be moved in any direction assigned to each item.

  Then, as a whole display mode, the display control unit 106 uses, as a reference, the position of the display information of the key content, on the display area that exists in the direction assigned for each item, The related content list screen on which the display information is arranged is displayed on the display unit 170. As the screen example, the screen example shown in FIG. 8 can be considered.

  The item display mode is a mode for displaying key content and display information of other content having a high degree of association with respect to one item. The item display mode is a display mode in which the screen can be moved only in the direction assigned to the one item and in the opposite direction.

  This display mode is switched from the whole display mode to the item display mode by the operation receiving unit 101 receiving a specific operation. As this specific operation, on the display area displayed on the display unit 170, other content arranged in the outermost periphery in the direction (for example, the x-axis positive direction) in which any one item is assigned. For example, an operation for focusing display information may be accepted. As another example, the operation receiving unit 101 may receive an operation for selecting an item (K1 to K4). Furthermore, although different from the present embodiment, the operation receiving unit performs an operation of moving the focus further outward from the display information of other content arranged on the outermost periphery in the direction in which any one item is assigned. It may be accepted.

  FIG. 16 is a diagram illustrating screen transition when switching to the item display mode when the operation receiving unit 101 receives a specific operation as described above. In the example illustrated in FIG. 16, when the operation reception unit 101 receives an operation to focus display information (C31 to C35) of other content, the display control unit 106 displays an item related to the item K1. Switch to. For this reason, the moving display is performed so that the display information of the key content and the display information group 1601 of other content having a high degree of association with the item K1 enter the display area 1610. At that time, the display control unit 106 moves the display information group 1604 of other contents having a high degree of association with the item K3 from the left side of the display area 1610 to hide it. Similarly, the display information group 1602 of other content having a high degree of association with the item K2 and the display information group 1603 of other content having a high degree of association with the item K4 are also moved out of the region and are not displayed.

  After the movement of the display information group described above, the display control unit 106 displays the related content list screen in the item display mode, as shown in the display area 1605. A specific description of the related content list screen in the item display mode will be described later.

  Further, the screen transition when switching from the entire display mode to the item display mode is not limited to the example shown in FIG. Therefore, a modification of the screen transition will be described. FIG. 17 is a diagram illustrating a modified example of the screen transition when switching to the item display mode when the operation receiving unit 101 receives a specific operation. As illustrated in FIG. 17, the display control unit according to the modification includes a display information group 1701 of other content having a high degree of association with the item K2, a display information group 1702 of other content having a high degree of association with the item K4, Is displayed after translucency. Other display information is displayed in the same manner as in the first embodiment. The screen transition is not limited to the examples shown in FIGS. 16 and 17 and can take various forms.

  Returning to the first embodiment, the display control unit 106 can switch to the item display mode for each item. FIG. 18 is a diagram illustrating a screen example for each item displayed in the item display mode. As illustrated in FIG. 18, when the focus movements 1501 to 1505 are performed in FIG. 15, the display control unit 106 displays a screen 1801 that displays display information of other content having a high degree of association with the item K2 as an item display. Display in mode.

  Further, when the focus movements 1506 to 1508 are performed, the display control unit 106 displays a screen 1802 on which display information of other content having a high degree of association with the item K1 is arranged in the item display mode. Similarly, when focus movements 1509 to 1513 are performed, a screen 1803 on which display information of other content having a high degree of association with the item K4 is displayed in the item display mode. Furthermore, when the focus movements 1514 to 1516 are performed, a screen 1804 on which display information of other contents highly related to the item K3 is arranged is displayed in the item display mode.

  Thus, when the display information on the outermost periphery of the display area is selected in the entire display mode, the related content list screen is displayed in the item display mode related to the item to which the content of the display information belongs.

  FIG. 19 is a diagram showing an example of a related content list screen in the item display mode displayed by the display control unit 106. In the example illustrated in FIG. 19, items other than the item K1 (items K2 to K4) that are currently displayed are displayed semi-transparently. Furthermore, the display control unit 106 can recognize that the display information of each content is arranged around the arc content by arranging the display information of each content in an arc shape. Note that the curvature of the arc is the same for the outer periphery after the second week from the innermost periphery. Thereby, it can display regardless of the number of display information of other contents.

  In the example illustrated in FIG. 19, every time the operation receiving unit 101 receives an operation of the cross key of the remote controller 90, the display control unit 106 displays display information of each content to be focused on (for example, display information C 101). To C105 and display information C201 to C205). For example, when the operation accepting unit 101 accepts an operation of moving the focus in the right direction (dashed line arrow) in the display information C201 to C205, the display control unit 106 moves all the display information of other content, The display information of the focused content is arranged in the area 1901. In this area 1901, the display information of the content immediately before the outermost periphery in the display area is arranged, so it is easy to determine whether or not there is content further outside (outermost position). In addition, this makes it easy to determine whether or not an outward operation is necessary, and improves operability.

  When the operation receiving unit 101 receives an operation for moving the focus in the left direction (solid arrow) in the display information C201 to C205, the display control unit 106 fixes the focus to the display information of the content in the area 1901. Release the focus and move the focus as usual. Further, when the operation receiving unit 101 receives an operation to move the focus in the left direction (dotted arrow) in the display information C35 to C31, the display control unit 106 switches from the item display mode to the whole display mode, Display the content list screen. When an operation with the other cross key is accepted (two-dot chain arrow), the focus is moved as usual.

  In this way, when the display control unit 106 displays in the item display mode, if the operation receiving unit 101 receives a specific operation, the display control unit 106 is again in the whole display mode in the related display mode. Display the content list screen. As a specific operation for returning to the whole display mode, display information of each content arranged in an ellipse shape with the key content as a center, and display information (for example, display information C35) arranged on the outermost one of the innermost circumferences. To C31), an operation for moving the focus to the display information arranged in the innermost periphery is accepted, or a press of a predetermined button (for example, a “return” button) of the remote controller 90 is accepted.

  FIG. 20 is an explanatory diagram showing switching between the whole display mode and the item display mode by the display control unit 106. As shown in FIG. 20, the display control unit 106 can scroll the screen up, down, left, and right on the display screen 2001 in the entire display mode. When the operation receiving unit 101 receives an operation for moving the focus to the arrows 2011 to 2013, the display control unit 106 switches to and displays the screen 2002 that is the item display mode. On the screen 2002 in the item display mode, screen scrolling is limited to the direction assigned to the item (left direction) and the opposite direction (right direction).

  When the operation receiving unit 101 receives an operation for moving the focus to the arrows 2021 to 2025 on the screen 2002 in the item display mode, the display control unit 106 switches to and displays the screen 2001 that is the entire display mode. . As for the screen transition at this time, it is assumed that the reverse process of the screen transition shown in FIG. 16 is performed.

  Next, screen transition when moving further in the direction assigned to an item in the item display mode will be described. FIG. 21 is an explanatory diagram showing screen transition when the focus is moved on the related content list screen displayed by the display control unit 106 in the item display mode. In the example shown in FIG. 21, when the operation receiving unit 101 receives an operation for moving the focus in the direction assigned to the item, in other words, the direction 2102 in which the relevance is low, The focus is fixed in the area 2101 and only the display information and items of other contents are moved on the screen.

  For example, when the operation receiving unit 101 receives an operation of moving the focus in the arrow 2112 (right direction) while the display information C211 is focused, the display control unit 106 is displayed in the display area 2103. The display information of all other contents excluding the key content is displayed by moving the display information by one display information in the opposite direction (left direction) to the arrow 2112. At this time, the content display information C201 to C205 is superimposed on the key content display information C1. Therefore, the display control unit 106 performs control for making all the display information C201 to C205 in the column overlapping the display information C1 transparent and non-display together with the above-described movement control.

  Further, when the operation receiving unit 101 receives an operation of moving the focus in the arrow 2113 (left direction) while the display information C211 is focused, the display control unit 106 is displayed in the display area 2103. The display information of all other contents excluding the key content is displayed by moving the display information by one display information in the opposite direction (right direction) to the arrow 2113. At that time, if there is display information of the content that has not been displayed by the above-described processing, it moves from the transparent state to the normal state as it moves to the right, and is placed at the position of C201 to C205. Become so. The key content display information C1 is always displayed. Thereby, it can be recognized that the current related content list screen is displayed with the key content as a reference.

  Further, display information of other contents superimposed on the key contents is not limited to being made transparent and not displayed. Therefore, the display information C1 of the key content is always displayed, and when the display information C1 and the display information of other content are superimposed, the display information C1 may be displayed semi-transparently to display the display information of the other content. Good. FIG. 22 is an explanatory diagram showing a modified example of the screen transition when the focus is moved on the related content list screen displayed by the display control unit 106 in the item display mode. In the example shown in FIG. 22, when the operation receiving unit 101 receives an operation for moving the focus in the direction assigned to the item, in other words, the direction 2102 in which the relevance is low, The focus is fixed within the range of the area 2201, and only display information and items of other contents are moved on the screen. Further, when the focus is changed, it is the same as in the first embodiment shown in FIG.

  When the display information C1 of the key content and the display information 2201 to 2206 of the other content are superimposed, the key content display information C1 is made semi-transparent and the key content is displayed on the display information 2201 to 2206 of the other content. The display control unit 106 displays so that the user can recognize that the display information C1 is arranged. By this display, the key content display information C1 is preferentially displayed over the display information of other content. The display is not limited to the display, and for example, the display information of other content may be hidden for the portion superimposed on the display information C1 of the key content.

  Further, when the operation receiving unit 101 receives an operation for focusing the other content on the outermost periphery, the display information of the other content moves to the left by one line of display information. The display control unit 106 does not display the display information that has moved out of the display area 2202 due to the movement.

  Returning to the first embodiment, the display mode switching process of the related content list screen in the digital television display device 100 according to the present embodiment configured as described above will be described. FIG. 23 is a flowchart showing the above-described processing procedure in the digital television display device 100 according to the present embodiment.

  First, the display control unit 106 displays a related content list screen in the entire display mode (step S2301). Next, it is determined whether the operation reception unit 101 has received an operation to move the focus to any of the display information of other content displayed on the related content list screen in the entire display mode (step S2302). If it is determined that it has not been received (step S2302: NO), the processing is performed again from step S2302.

  On the other hand, when the operation reception unit 101 determines that an operation to move the focus has been received (step S2302: Yes), the display control unit 106 performs display for moving the focus to the display information of the other content of the movement destination. (Step S2303). Then, the display control unit 106 focuses on the display information of the other content on the outermost periphery among the display information of the other content arranged in an ellipse shape with the display information of the key content as the center on the related content list screen. It is determined whether or not it has moved (step S2304). When it determines with not having moved (step S2304: No), a process is started again from step S2302.

  On the other hand, when the display control unit 106 determines that the focus has moved to the display information of the other content on the outermost periphery (step S2304: Yes), the direction in which the display information of the other focused content is arranged The related content list screen is displayed in the item display mode for the item assigned to (step S2305).

  Next, it is determined whether the operation reception unit 101 has received an operation to move the focus to any of the display information of other content displayed on the related content list screen in the item display mode (step S2306). If it is determined that it has not been received (step S2306: NO), the processing is performed again from step S2306.

  On the other hand, when the operation reception unit 101 determines that an operation to move the focus has been received (step S2306: Yes), the display control unit 106 performs display for moving the focus to the display information of the other content at the movement destination. (Step S2307). Then, the display control unit 106 determines whether or not the focus has moved to the display information of the other content arranged in the outermost periphery in the direction assigned to the item in the display area of the related content list screen (step) S2308).

  When the display control unit 106 determines that the focus has moved to the display information of other content arranged at the outermost periphery (step S2308: Yes), the display information of the other focused content is one of the outermost periphery. The display information of all other contents other than the key contents is moved so as to come forward (step S2309). The screen transition at this time is as shown in FIG.

  On the other hand, when the display control unit 106 determines that the focus has not moved to the display information of other content arranged at the outermost periphery (step S2308: No), the other content arranged at the innermost periphery It is determined whether or not the focus has moved to the display information (step S2310). When it determines with not moving (step S2310: No), it starts from step S2306.

  On the other hand, when the display control unit 106 determines that the focus has moved to the display information of other content arranged in the innermost periphery (step S2310: Yes), the display control unit 106 switches from the item display mode to the whole display mode again. The related content list screen is displayed (step S2301).

  With the processing procedure described above, the digital television display device 100 switches between the entire display mode and the item display mode based on the user's operation on the related content list screen, so that a display suitable for the user's operation is performed. .

  The display control unit 106 of the digital television display device 100 according to the present embodiment does not perform display in which display information of other content is arranged in an oblique area centering on the display information C1 of key content. This eliminates the need for screen scrolling in the vertical direction from the direction assigned to the item in the item display mode.

  As a result, the screen is not scrolled in the oblique direction by the direction component assigned to the item and its vertical component. Thereby, even a person who is not accustomed to scrolling in an oblique direction or a person who gets drunk by scrolling in an oblique direction can use the related content list screen.

  By the way, in a normal television display device, a simple behavior is demanded by a user as an operation for the device. On the other hand, in the digital television display device 100 according to the present embodiment, it is not necessary to move the screen in an oblique direction while browsing related content, and the operation can be easily performed by limiting to the screen scroll described above. It became possible to do. Thereby, in order to realize portability and simple operation, such as the remote controller 90, the operation can be easily performed even with an input device in which the number of buttons, the operation method, and the like are limited.

  In the digital television display device 100 according to the present embodiment, the related content list screen described above is displayed, and the display is switched between the whole display mode and the item display mode. In the whole display mode, the screen can be scrolled vertically and horizontally, whereas in the item display mode, the screen can be scrolled only in the direction assigned to the item and in the opposite direction. Thereby, operation at the time of displaying a screen can be facilitated.

  The display control unit 106 of the digital television display device 100 displays items on the top, bottom, right, and left with the key content as the center. At that time, “person” and “genre” were arranged as items on the left and right. This is because the item is referred to by the user better than the other two. That is, it is because a person in the horizontal direction does not feel uncomfortable in screen scrolling and is easy to visually recognize. This makes it easy for the user to search for related content.

  The digital television display device 100 is provided with a control unit that assigns the items designated as important in the order of right, left, down, and top when the user accepts the designation of four items considered important in order. Also good. As a result, the display information of each content can be browsed without any sense of incongruity by scrolling the screen for items that the user has determined to be important.

  Moreover, it is not limited to each embodiment mentioned above, The various deformation | transformation which is illustrated below is possible.
