  Exemplary embodiments of a display processing apparatus and a display processing method according to the present invention will be explained below in detail with reference to the accompanying drawings. In the following embodiments, an example in which the display processing device according to the present invention is applied to a television (TV) is shown. However, the present invention is not limited to this, and a video or the like can be displayed on a display device or the like. The present invention can be applied if it is. When the user searches for key content that is a search key and content related to the key content from a plurality of contents, when the user selects the key content, the display processing apparatus according to the present embodiment selects the key content. A plurality of contents related to the key contents are displayed together with the contents.

  First, the functional configuration of the display processing apparatus 100 will be described. FIG. 1 is a block diagram illustrating a configuration of a display processing apparatus 100 according to the embodiment. As shown in FIG. 1, the display processing apparatus 100 includes an electronic program guide storage unit 150, a recorded program storage unit 160, a display unit 170, a broadcast receiving unit 108, and an IPTV (Internet Protocol TeleVision) connection unit 180. And is connected to the IPTV server 200 via a network. In addition, the display processing device 100 includes a processing device such as an ASIC or a CPU, a ROM that stores a predetermined program for controlling the operation of the display processing device 100, and a storage device such as a RAM that is a work area of the processing device. And the electronic program guide storage unit 150, the recorded program storage unit 160, the remote control operation reception unit 101, and the metadata search, in cooperation with the processing device and the program stored in the storage device. The functional units of the unit 102, the metadata acquisition unit 103, the relevance calculation unit 104, the display information generation unit 105, the display control unit 106, and the video reproduction unit 107 are realized.

  The IPTV server 200 is a server that provides a service for distributing video such as a TV program or a movie using IP, and distributes content such as the video and metadata of the content in response to a request from the display processing device 100. To do.

  The IPTV connection unit 180 is an interface that connects the display processing apparatus 100 and the IPTV server.

  The electronic program guide storage unit 150 is a storage medium such as an HDD or a memory that stores an electronic program guide acquired from an external server that manages and distributes an electronic program guide (EPG). 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 via a communication unit (not shown). A stored electronic program guide is stored. Here, it is assumed that the electronic program guide includes information on programs broadcast from the present to a certain time in the future (for example, one week later).

  The recorded program storage unit 160 is a storage medium such as an HDD or a memory that stores content such as video. For example, when the display processing apparatus 100 is a TV equipped with an HDD, the recorded program storage unit 160 stores video content in which a TV program or the like is recorded. Further, a DVD (Digital Versatile Disk) video, a video captured by a video camera, or the like may be used as the content.

  In addition, the recorded program storage unit 160 stores metadata related to the content in association with each content. Here, the “metadata” is a group of information indicating characteristics unique to each content, and includes the title of each content, the broadcast date and time, and the like. For example, when the content is a TV program, information (program information) such as a TV program title, channel, broadcast date and time, performers, program contents, and genre becomes metadata, and this metadata is provided together with the content. It is stored in the recorded program storage unit 160.

  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, the aspect in which the metadata is provided in a preset state has been described. However, the present invention is not limited to this, and the user is provided via an input device 90 such as a remote controller (hereinafter referred to as a remote controller). The information input from may be stored as metadata in the recorded program storage unit 160 in association with the content.

  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. In addition, the display unit 170 displays display information representing the contents of the content generated by the display information generation unit 105 described later (see FIGS. 3A and 3B) so that the user can search for the content.

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

  The video reproduction unit 107 is a video content that the user desires to reproduce, that is, a content such as a TV program received by the broadcast reception unit 108, a video content acquired from the IPTV server 200 via the IPTV connection unit 180, or a recorded program The video content stored in the storage unit 160 is acquired, and the acquired content is decoded (reproduced) and transmitted to the display control unit 106.

  The remote control operation accepting unit 101 recognizes that the operation button provided on the remote control 90 has been pressed by the user and accepts the operation. 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 with the operation buttons provided on the remote controller 90, the remote control operation reception unit 101 receives the key content selection operation. The content being played back may be the key content. In this case, when the user presses the operation button provided on the remote controller 90 during the content playback, the remote control operation reception unit 101 displays the content being played back. A selection operation using the key content, that is, an operation for searching for content is accepted. Although details will be described later, the remote control operation accepting unit 101 performs an instruction operation on the display information of the content of interest (target content) from the list information on which the display information of the plurality of contents displayed on the display unit 170 is displayed. Accept.

  The metadata acquisition unit 103 acquires metadata of all content (key content and other content other than the key content) when the remote controller operation reception unit 101 receives a key content selection operation. Specifically, for example, the metadata acquisition unit 103 acquires content metadata from the recorded program storage unit 160. Also, the metadata acquisition unit 103 requests content metadata from the IPTV 200 server, 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 remote control operation accepting unit 101 accepts a key content selection operation, the metadata search unit 102 retrieves the key content metadata from the content metadata obtained by the metadata obtaining unit 103, and retrieves the searched key. The content metadata is sent to the relevance calculation unit 104. Further, the metadata search unit 102 uses the metadata of the content of the key content acquired by the metadata acquisition unit 103, and the metadata of other content for which the relevance calculation unit 104 calculates the relevance with the metadata. And the metadata of the other searched content is transmitted to the relevance calculation unit 104.

  Further, when the remote control operation accepting unit 101 accepts a key content selection operation, the metadata search unit 102 sends all the content metadata acquired by the metadata acquiring unit 103 to the display information generating unit 105.

  Based on the selected key content metadata and other content metadata sent from the metadata search unit 102, the relevance calculation unit 104 determines the relevance of each of the other contents to the key content as metadata. Are calculated for each item, for example, 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 {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 represented by a weighted linear sum of the following relevance levels RM _{1 to} RM ₅ .
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.

Here, an example using g, which is a function of g (x) = MO1 / | X |, when fa ₁ (M11, M21) = g (rec_data (M11) −rec_data (M21)) is shown. 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, 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 MO2 / 2 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 other content from the metadata of the key content and the metadata of other content transmitted from the metadata search unit 102. Specifically, for example, the display information generation unit 105 displays the content by attaching a title or the like to the representative image of the video data based on the metadata of the video data stored in the recorded program storage unit 160. Display information that can be displayed on the unit 170 is generated. Further, for example, the display information generation unit 105 can display the content on the display unit 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. Generated display information. Further, for example, the display information generation unit 105 can display the TV program title, broadcast date and time, channel, program content, and the like on the display unit 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. 3A and 3B are diagrams illustrating examples of display information representing the contents. In FIG. 3A, for example, the key content display information C <b> 1 is generated based on the metadata of the 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. . Also, in FIG. 3B, for example, the key content display information C1 is generated based on the 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” "Nizainau" 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.

  Further, as described above, when the remote control operation receiving unit 101 receives an operation for searching for content from the user, the display control unit 106 displays the key content display information and the key content for the user to search. List information that displays a list of display information of other related contents is displayed.

  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 of the operation button, for example, the operation button of the cross key. In addition, the list information is arranged in the descending order of the degree of relevance from the vicinity of the center in the predetermined area sorted for each item from the center toward the radial direction. 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. FIGS. 4A to 8 are explanatory diagrams relating to details of the display information display operation.

  First, as illustrated in FIG. 4A, 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 1-4) in the positive y-axis direction and the negative y-axis direction are set, and items included in the metadata of the selected key content are allocated and arranged on each axis. Referring to FIG. 2, for example, items included in the metadata include “title” of a TV program (content), “person” indicating a performer, “keyword” when performing a search included in the program content, TV Assign “genre” etc. of the program. 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. 4B, 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. 5, the display control unit 106 is on a plurality of octagons F1, F2,... Formed concentrically around the position of the display information C1 of the key content. 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. 6, 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 outside. Arrange in descending order. That is, as shown in FIG. 5, the display control unit 106 arranges display information of other content having the highest degree of association with the key content on the octagon F1, and further, on F2, F3. 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. 7, the display control unit 106 includes 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. 7 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.

  Also, as shown in FIG. 8, 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 unit 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. 9 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. In the list information of FIG. 9, items of “title” on the upper side, “person” on the right side, “keyword” on the lower side, and “genre” on the left side are displayed. Display information of other contents is arranged from the vicinity of the center toward the outside.

  Further, in the present embodiment, the display information of other contents is arranged in a shape along the up, down, left, and right operation directions. For example, when the content of interest during the search is the display information C30, the left and right instructions are indicated by the operation buttons. When the operation is accepted, the attention content changes as indicated by an arrow A. Further, when the content of interest during the search is the display information C30, the content of interest changes as indicated by an arrow B when an up / down instruction operation is accepted by the operation button. Further, for example, when the attention content is the display information C11, if the instruction operation is received and the cursor is moved to the right by one cursor, the attention content is changed to the display information C36. Similarly, the content of interest changes to display information C22 when the cursor is moved up, display information C12 when the cursor is moved left, and display information C18 when the cursor is moved down. This makes it easy to perform an instruction operation from an operation button such as a cross key on the remote controller 90.

  Next, display information display processing by the display processing apparatus 100 configured as described above will be described. FIG. 10 is a flowchart showing the flow of display information display processing by the display processing apparatus 100.

  First, the remote control operation reception unit 101 waits until a key content selection operation is received from the operation buttons of the remote control 90 (step S10). When the selection operation is received (step S10: Yes), the metadata acquisition unit 103 acquires the metadata of the selected key content (step S11). Next, the metadata acquisition unit 103 acquires metadata of content other than the key content (step S12).

  Then, the relevance calculation unit 104 calculates the relevance of each of the other contents with respect to the key content for each item included in the metadata (step S13). Then, the display control unit 106 generates list information in which display information of the key content and the other content is arranged according to the degree of relevance of each of the other contents with respect to the key content (Step S14), and displays the generated list information. The data is displayed on the unit 170 (step S15).

  In this way, on a plurality of polygons that are concentrically formed around the position of the display information of the key content serving as a search key, and in a shape that follows the operation direction by the operation button, the degree of relevance is measured from the vicinity of the center. By displaying the list information in which display information of other contents is arranged in descending order, the user can easily search for contents related to the key contents from an enormous amount of contents by operating from the remote controller 90.

  Returning to FIG. 1, the display control unit 106 further includes a scroll unit 109, and further includes the following functions. When the remote controller operation accepting unit 101 presses the operation button of the remote control 90 and receives an instruction operation for instructing display information of the content of interest (target content), the scroll unit 109 displays the list information in the operation direction. Scrolling is performed by moving within a predetermined display range. At this time, the display control unit 106 maintains the display of the key content display information within the display range regardless of the amount of movement of the list information by the scroll of the scroll unit 109. Further, the display control unit 106 increases the display size of the display information of the other content that has been instructed by the operation from the operation button and has become the attention content, larger than the display size of the display information of the other content that has not been instructed. indicate.

  11-1, 11-2, and 11-3 are explanatory diagrams when scrolling the list information in which the display information of the key content and the display information of other content are arranged. FIG. 11A shows the initial list information in which the display information of the key content is arranged at the center, and the key content is the content of interest. From here, when an instruction operation in which the user presses the right direction of the operation button four times is accepted, the cursor is moved to the right by four cursors, and the display information C81 of other content is displayed as the content of interest. As shown in FIG. 2, the list information is scrolled four times to the left. Note that the amount of movement of one scroll is set in advance. Further, by accepting an instruction operation in which the right direction of the operation button is pressed three times by the user, the cursor is moved to the right by three cursors, that is, seven cursors from the initial state, and the display information C82 of the other content is changed to the content of interest. Is displayed, the list information is scrolled seven times to the left as shown in FIG.

  At this time, since the display information of the key content is always displayed within the display range even if the initial display position moves outside the display range, the initial display is performed when the list information is scrolled four times to the left from the initial state. Assuming that the position has moved out of the display range, the movement amount (A) of the key content display information C1 when the scrolling is moved four times to the left from the initial state is also the key content display information C1 when the scrolling is moved seven times to the left. The movement amount (B) of the key content is not changed, and the display of the key content display information C1 is maintained at the same position.

  When the list information is moved by scrolling the scroll unit 109, the display control unit 106 displays an initial display when the initial display position where the key content display information C1 was initially displayed is moved out of the display range. The key content display information is displayed together with the direction indication display indicating the direction of the position. FIG. 12 is an explanatory diagram when the list information in which the display information of the key content and the display information of the other content are arranged is scrolled. In FIG. 12, by accepting an instruction operation in which the user presses the right direction of the operation button 6 times and the upward direction 6 times, the cursor is moved to the right by 6 cursors and 6 cursors to the right. This is a case where the display information C83 is displayed as the content of interest. At this time, the initial display position of the key content display information C1 has moved outside the lower left display range (see the display information drawn outside the display range in FIG. 12). A direction indication display indicating the direction of the initial display position is displayed together with the key content display information C1 by the apex of the triangle.

  Further, the display control unit 106 changes the display size of the direction indication display to be smaller as the distance between the display position of the key content display information C1 and the initial display position of the key content display information C1 increases. To do. FIGS. 13A and 13B are explanatory diagrams of the direction indication display indicating the direction of the initial display position in the key content display information C1. Since the display position of the key content display information C1 and the initial display position of the key content display information C1 are short (see FIG. 13A), the display position of the key content display information C1 and the display of the key content are displayed. When the distance from the initial display position of the information C1 is far (FIG. 13-2), the display size of the direction indication display is displayed smaller.

  In this way, the display size of the direction indication display is displayed in proportion to the distance between the display position of the key content display information C1 and the initial display position of the key content display information C1, so that the user can display the key content. It is possible to roughly grasp the distance between the display position of the information C1 and the initial display position of the display information C1 of the key content. Here, the display size of the direction indication display is changed according to the distance between the display information C1 of the key content and the initial display position, but the distance of the direction indication display is changed according to the distance. May be represented.

  Further, when the list information is moved by scrolling the scroll unit 109 and the number of items in the display range changes, the display control unit 106 changes the display of the items in the display range according to the change. That is, when the list information is moved by scrolling the scroll unit 109, the display control unit 106 moves the display information of the other content belonging to the item assigned to the axis within the display range to the outside of the display range. When the number decreases, the reduced items are hidden from the display unit 170. FIG. 14 is an explanatory diagram of the list information when the number of items in the display range changes. As shown in FIG. 14, when the list information is scrolled four times to the left from the initial display range, for example, when all the display information of other content belonging to the “genre” item on the left side is moved out of the display range, Hide the “Genre” item.

  In addition, when the list information is moved by scrolling the scroll unit 109, the display control unit 106 moves display information of other contents belonging to the items assigned to the axes in the display range from the display range to the display range. When the number of items increases, the increased items are additionally displayed. As shown in FIG. 14, when the list information is scrolled four times to the right from a certain state, for example, display information of other content belonging to the “genre” item on the left side moves from outside the display range to within the display range. In this case, the item “genre” is additionally displayed.

  Next, the scrolling process of the list information by the display processing apparatus 100 configured as described above will be described. FIG. 15 is a flowchart showing the flow of the list information scroll process by the display processing apparatus 100.

  First, the remote control operation reception unit 101 stands by until an instruction operation for instructing display information of the content of interest is received (step S20). When the instruction operation is received (step S20: Yes), the scroll unit 109 scrolls by moving the list information in the operation direction (step S21). Then, the display control unit 106 displays the display size of the display information of the content of interest instructed by the operation from the operation button larger than the display size of the display information of the other content not instructed (step S22). .

  Then, the display control unit 106 determines whether or not the initial display position of the display information of the key content has moved outside the display range (step S23). When the initial display position has not moved outside the display range (step S23: No), the process returns to step S20 and is repeated. On the other hand, when the initial display position has moved outside the display range (step S23: Yes), the display control unit 106 displays the key content display information together with the direction indication display indicating the direction of the initial display position ( Step S24).

  Next, the display control unit 106 determines whether or not the number of items in the display range has changed (step S25). If the number of items has not changed (step S25: No), the process returns to step S20 and the process is repeated. On the other hand, when the number of items is changing (step S25: Yes), the display control part 106 changes the display of an item according to the change (step S26). That is, the display control unit 106 hides the decreased items when the number of items decreases, and additionally displays the increased items when the number of items increases.

  Next, the scrolling process of the list information by the scroll unit 109 will be described according to the transition diagram of the screen displayed on the display unit 170. FIG. FIGS. 16 to 20 are screen transition diagrams when the list information in which the display information of the key content and the display information of other contents are arranged is scrolled to the left.

  First, when a key content selection operation is received by the remote control operation receiving unit 101, as shown in FIG. 16, the key content display information C1 is arranged at the center, and the key content display information C1 becomes the content of interest. List information is displayed. This is the initial display range.

  When an instruction operation using the display information C18 of other content as the content of interest is received from the display information C1 of the key content, the cursor moves to the right by one cursor and the list information is scrolled to the left by one. The section 170 displays the list information shown in FIG.

  When an instruction operation using the display information C35 of the other content as the content of interest is received from the display information C18 of the other content, the cursor is further moved to the right by one cursor and the list information is scrolled to the left by one. The display unit 170 displays the list information shown in FIG.

  When an instruction operation using the display information C62 of the other content as the content of interest is received from the display information C35 of the other content, the cursor is further moved to the right by one cursor and the list information is scrolled to the left by one. The display unit 170 displays the list information shown in FIG. At this time, since the display information of other contents belonging to the item “genre” is all moved out of the display range, the number of items is reduced from within the display range, so the reduced item “genre” is not displayed.

  When an instruction operation using the display information C84 of the other content as the content of interest is received from the display information C62 of the other content, the cursor is further moved to the right by one cursor and the list information is scrolled to the left by one. The display unit 170 displays the list information shown in FIG. At this time, since the initial display position of the key content display information C1 moves out of the display range, the key content display information C1 is displayed together with the left direction indication indicating the initial display position. Also, since the initial display position of the key content display information C1 has already moved out of the display range, even if the list information is further scrolled to the left, the key content display information C1 does not change the display position. The distance between the display position of the key content display information C1 and the initial display position of the key content display information C1 is represented by the display size of the direction indication display.

  Next, a case where the list information is scrolled down will be described. FIG. 21 shows the list information when the list information in which the display information of the key contents and the display information of other contents are arranged is scrolled down five times. As shown in FIG. 21, when an instruction operation using the display information C88 of other content as the content of interest is received from the display information C1 of the key content, the list information is scrolled down five times while moving up by five cursors. . At this time, since the initial display position of the key content display information C1 moves out of the display range, the key content display information C1 is displayed together with the downward direction indication indicating the initial display position.

  Next, a case where the list information is scrolled left and down will be described. FIG. 22 shows the list information when the list information in which the display information of the key content and the display information of other contents are arranged is scrolled 5 times to the left and 5 times downward. As shown in FIG. 22, when an instruction operation using the display information C90 of other content as the content of interest is received from the display information C1 of the key content, the cursor moves to the right by 5 cursors and moves upward by 5 cursors, and the list information Is scrolled 5 scrolls to the left and 5 scrolls down. At this time, since the initial display position of the key content display information C1 moves out of the display range, the key content display information C1 is displayed together with the direction indication display in the lower left direction indicating the initial display position.

  In this way, even when the list information is scrolled, the key content display information is always displayed within the display range, so that the user can grasp the initial display position of the key content display information by operating from the remote controller 90. From a vast amount of content, it is possible to easily search for content related to key content serving as a search key.
