  The present invention relates to an information processing apparatus and method for displaying data broadcast content included in, for example, digital broadcasting, and a technical field of a computer program that causes a computer to function as such an information processing apparatus.

  As this type of device, for example, a television that receives and displays data broadcast content broadcast by terrestrial digital broadcast, BS (Broadcast Satellite) digital broadcast, or the like is known.

Such data broadcast content may include a display object called a so-called scroll area in content displayed on the display screen.
A display object that is a scroll area has, for example, one or a plurality of display items within the display range. The display items are displayed on the display screen in such a manner that at least a part is visible to the user and the other part is invisible. By receiving an input such as a user operation on the content, a part of the display items that can be visually recognized cannot be visually recognized by moving in the vertical or horizontal direction. At the same time, due to the movement, other part of the display items that cannot be visually recognized move within the display range, and can be visually recognized. Such an operation is generally called a scroll operation because the display items displayed in the display range operate so as to scroll (in other words, slide). A display object that displays a display item that performs a scroll operation is called a scroll region.

  Since the scroll region is in a state where some display items cannot be visually recognized, the user needs to perform an operation for performing a scroll operation in order to view all the display items. In addition, the user may not be able to recognize the scroll area simply by looking at the visible display items. In any case, the user is inconvenienced to see the display contents of the scroll area included in the content, and may have an impression that the operability of the content is poor.

  For this reason, techniques for processing content that improves the operability and visibility of the scroll region have been studied. For example, Patent Document 1 discloses a user operability and a window for performing a scroll operation included in content. A configuration for providing a scroll bar that further improves visibility is described.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments relating to an information processing apparatus and method, a computer program, and an information recording medium according to the present invention will be described below as the best mode for carrying out the invention.

(Embodiment of information processing apparatus)
An embodiment according to the information processing apparatus of the present invention includes: an acquisition unit configured to acquire content including object information defining at least one display object; and key event information defining at least one process corresponding to an operation input; In an aspect in which at least a part of the display object is visible on the display screen by analyzing the content with an output unit that outputs the content with respect to a display unit that displays the content on the display screen. Determination means for determining whether or not the display item is a scroll object, the display item being displayed, and scrolling the display item by changing at least one of display content and display position of the display item. .

  According to the embodiment of the information processing apparatus of the present invention, first, content is acquired by the operation of the acquisition means. The acquired content is displayed on a display screen or the like provided in the display unit by the operation of the output unit.

  The content according to the present embodiment includes some display object displayed by the display means that can be visually recognized, in other words, identified by the user, and some processing corresponding to some operation input via the operation means such as a remote controller, for example. .

  The display object according to the present embodiment is intended to indicate any object displayed on the display screen, such as a window or an image. The object information is information that defines, for example, display contents, display positions, display ranges, and the like for display objects that are actually displayed on the display screen. The object information is information that defines the display mode of the display object, such as the display position, display range, and display content of the display object.

  The processing according to the present embodiment is intended to indicate some processing executed in response to a user operation or the like in relation to content. The key event information is information describing the processing details of processing executed in response to an operation by the user, and indicates, for example, a script that defines processing details in the data broadcast content. The key event information includes, for example, information indicating an operation input such as an operation input serving as a trigger for the corresponding process, a change in display mode of the display object according to the process, and the like.

  The determination unit determines whether the display object included in the content is a scroll object by analyzing the content. A scroll object is a kind of display object, has a display item that is displayed in a manner that is at least partially visible on the display screen, and changes at least one of display content and display position of the display item. Thus, the display items are scroll-displayed. The state in which a part is displayed in a visible manner is, for example, a display item such as an image, a button, a selection item, or a sentence to be displayed on a display object that is one window, in other words, another display object. When the display range occupies a wider range than the display range of the window on the display screen, at least a part of the display range is displayed in the window. Scrolling a display item by changing at least one of the display content and the display position is so-called scrolling by moving the display item to slide (in other words, scrolling) in the display window or changing the display content. The purpose is to realize the operation.

  The scroll object may be defined, for example, by the object information and the key event information, the contents of display, the number and contents of display items, and the mode of the scroll operation. Specifically, it may be described in a predetermined format by some programming language such as Java (registered trademark) (for example, JScrollPanel class in Java). A CPU (Central Processing Unit), which is an example of a determination unit, can relatively easily determine a scroll object by analyzing the content if the programming language describing such a scroll object can be read and executed. .

  In addition to such scroll objects, for example, scroll objects constituted by descriptions other than the default format may be treated as scroll objects according to the present invention. Further, the present invention is also a collection of a plurality of display objects that are individually set for processing, and can be recalled that a scrolling operation is performed for the user by comprehensively looking at the operation of each display object. May be handled as a scroll object. For example, it is also an example of the scroll object of the present invention that a plurality of buttons arranged side by side are changed so that the display content is scrolled as a result of changing the display content by processing according to the operation input.

  A specific content analysis mode will be described in detail later.

  According to such a configuration, it is possible to determine whether or not the display object included in the content acquired by the acquisition unit is a scroll object. In the conventional information processing apparatus, although it is possible to detect a scroll area described in a common format such as a programming language, the same operation as the scroll operation is performed by using other formats or other configurations. There is a technical problem that the scroll object to be detected cannot be detected.

  According to the present embodiment, the scroll object can be suitably detected by analyzing the content. For this reason, using the detection result of the scroll object, for example, the display items displayed in the scroll object can be displayed in a manner more convenient for the user, the visibility of the scroll object itself can be improved, The convenience of content can be improved by various methods such as improvement of operability.

  In the present embodiment, the display unit may be included as a component of the information processing apparatus. An example of such a configuration is a display-integrated information device (for example, a television). The display unit may be configured as a component outside the information processing apparatus. As such a configuration, an information device separate from the display (for example, a personal computer main body connected to the display, a DVD / BD recorder, or the like) can be cited as an example.

  In one aspect of the embodiment of the information processing apparatus according to the present invention, the information processing apparatus further includes key event input means for inputting a key event indicating the content of the operation input for the content, and the determination means responds to input of the key event Then, it is determined whether or not the display object is the scroll object by analyzing a change that occurs in the display content of the display object.

  According to this aspect, the determination unit analyzes the change in the display content of the display object by the process corresponding to the operation input indicated by the key event input by the key event input unit. For example, a plurality of display objects are arranged in the vertical and horizontal directions, and the display contents change so that the plurality of display objects slide or move in a designated direction by a key event that designates the arrangement direction. In this case, the plurality of display objects are likely to be display items constituting the scroll object.

  In a general scroll object, a display item displayed in the object is scrolled by a user operation or some automatic processing. For example, the determination unit includes in advance data regarding changes in display contents that satisfy the conditions of the scroll operation, such as the above-described operation, and compares the data with changes in display contents due to processing according to operation input. Thus, it may be determined whether or not the object is a scroll object.

  When detecting a change in the content of the display that satisfies the conditions for the scroll operation, the determination unit determines that the display object or a set of the detected motion is a scroll object.

  With this configuration, the determination unit can detect the scroll area included in the content based on the change in the display content on the display screen in response to the input of the key event.

  Note that the key event input and the processing corresponding to the input do not necessarily have to be actually executed. The analysis of the determination unit according to this aspect may be realized by analyzing the processing content virtually realized on the CPU, for example.

  In another aspect of the embodiment of the information processing apparatus of the present invention, the determination means analyzes the object information and the key event information that define a change that occurs in the display content of the display object by the processing. Then, it is determined whether or not the display object is the scroll object.

  According to this aspect, the determination unit detects a change occurring in the display object from the object information and the key event information by the process according to the operation input and the process specified by the key event information. Then, the determination unit determines whether or not the display object is a scroll object by determining whether or not a change that occurs in the display object satisfies the above-described condition as the scroll object.

  With this configuration, it is possible to detect the scroll object included in the content from the object information that defines the content and the key event information. In this configuration, the determination unit determines the scroll object based on whether or not the object information and the key event information include information defining the operation related to the scroll operation. For this reason, the determination means can be suitably detected even for a scroll object that is not defined in a predetermined format such as a programming language.

  In another aspect of the embodiment of the information processing apparatus of the present invention, the determination unit determines whether the display object is the scroll object by analyzing the display content of the display object.

  According to this aspect, the determination means determines whether or not the object is a scroll object by analyzing the arrangement position of the display object on the display screen and the display content such as the layout and the displayed image.

  In general, a scroll object often has an appearance feature that reminds a user who views content to perform a scroll operation. For example, for a set of display objects in which a plurality of display items each having a display range of the same size are arranged in the vertical and horizontal directions and a part is hidden behind the window, the user can perform a scrolling operation. Think of it as possible. Therefore, the determination unit can detect the scroll object with high accuracy by analyzing the object information and determining that the display object having such an appearance characteristic is the scroll object.

  In addition, as an example of a scroll object in which display items are arranged vertically or horizontally, a so-called scroll bar configured by display of arrows or the like is arranged adjacent to the arrangement of display items. For example, the determination unit may detect such a scroll bar by image analysis such as pattern matching, thereby determining whether or not the object is a scroll object.

  With this configuration, the determination unit can detect the scroll object from the display content on the display screen. For this reason, it is possible to suitably detect a scroll object that cannot be read from the key event information.

Examples of the display 141 include a liquid crystal display, a plasma display, a cathode ray tube display, and an organic EL display.

  The controller 142 is a device that inputs a user operation on content displayed on the display 141. As an example of a user operation, the controller 142 can specify, for example, an operation for specifying a direction such as a vertical or horizontal direction in the display screen, an operation for directly specifying some display object to be displayed, or a coordinate on the display screen. An operation such as an operation is received, and the operation content is input to the input / output unit 140. The controller 142 is an input device that can directly or indirectly specify an arbitrary position on the display screen of the display 141. Examples of the controller 142 include a mouse, a touch pad, and a touch panel integrated with the display screen of the display 141. As mentioned.

  The display 141 and the controller 142 may be independent devices provided outside the data broadcast receiving apparatus 100, and the data broadcast receiving apparatus 100 may be configured not to include the display 141 and the controller 142. In such a configuration, the input / output unit 140 may be treated as an example of the “output unit” and “display unit” of the present invention in that the content is displayed on an external display device. .

  The bus 150 is a signal input / output bus that connects the units included in the data broadcast receiving apparatus 100.

  Next, the function of the CPU 120 will be described with reference to FIG. FIG. 2 is a conceptual diagram illustrating the functions of the CPU 120 as functional units for convenience.

  The CPU 120 includes a content acquisition unit 121, a display processing unit 122, a content analysis unit 123, a key event input unit 124, a change information analysis unit 126, a display information analysis unit 126, and scroll information as functional units for convenience. A storage unit 127.

  The content acquisition unit 121 acquires the content acquired by the reception unit 110 and inputs the content to the display processing unit 122 and the content analysis unit 123.

The display processing unit 122 performs processing for displaying the content acquired by the content acquisition unit 121 on the display 141. In addition, the display processing unit 122 inputs display information related to content display to the change information analysis unit 125 and the display information analysis unit 126. Further, when a change occurs in the content display, the display processing unit 122 inputs display change information indicating the change in the display to the change information analysis unit 125.
In addition, the display processing unit 122 performs a process of changing the display content on the display 141 in accordance with a virtual user operation or the like input from the key event input unit 124.

  The content analysis unit 123 is an example of the “detection unit” of the present invention, and refers to BML data or the like constituting the content acquired by the content acquisition unit 121 and detects a scroll area included in the content. . The content analysis unit 123 inputs information including the display position, display range, display item, and the like of the detected scroll area to the scroll information storage unit 127.

  The key event input unit 124 virtually inputs a user operation (in other words, a key event) that can be received in the displayed content to the display processing unit 122.

  The change information analysis unit 125 is an example of the “detection unit” of the present invention, and detects a scroll area included in the content based on a change in the display information of the content input by the display processing unit 122. To do. Specifically, the change information analysis unit 125 instructs the key event input unit 124 to virtually input a key event for the content displayed by the display processing unit 122. Thus, in response to a key event virtually input from the key event input unit 124, the content of the content displayed by the display processing unit 122, in other words, the change in the content of the display information is analyzed, so that Detects the scroll area contained within. The change information analysis unit 125 inputs information related to the detected scroll area to the scroll information storage unit 127.

  The display information analysis unit 126 is an example of the “detection unit” of the present invention, and detects a scroll area included in the content based on the display information of the content input by the display processing unit 122. For example, when the content displayed on the display screen includes a display object that can be determined as a scroll area, such as a display window in which a plurality of display items are arranged and an arrow-shaped display indicating the scroll direction is included, the display object Is determined to be a scroll area. The display information analysis unit 126 has, for example, pattern matching data for determining whether or not the display object in the content is a scroll area in the memory 130, and scrolls by referring to the data. An area may be detected. The display information analysis unit 126 inputs information related to the detected scroll area to the scroll information storage unit 127.

  The scroll information storage unit 127 records and manages information related to the scroll area. For example, the scroll information storage unit 127 manages the scroll area in each content by storing information related to the input scroll area in a database formed in the memory 130.

  With reference to FIG.3 and FIG.4, the content and scroll area | region in this invention are demonstrated. FIG. 3 is an example of data broadcast content displayed on the display screen of the display 141. FIG. 4 is a diagram showing a change in display of the scroll area in the content in response to a key event input, in other words, an operation.

  The content shown in FIG. 3 includes a data broadcast display area 210, a scroll area 220, and objects 230, 240, and 250 that are non-scroll areas on the display screen 200.

  In the data broadcasting content which is an example of the content of the present invention, typically, the user performs an operation of designating a direction or an operation directly corresponding to the displayed display object through a key provided in the controller 142. Perform the operation. A display object that can be selected by an operation for specifying a direction or the like may include, for example, display items included in the display range of the display object that is a scroll area.

  In such a scroll area, the number of components that are actually included is more defined than the number of components that are always displayed. By sequentially switching and selecting the components, the user hides them outside the scroll area. Can be recalled to the front of the display. Such a region is defined as a scroll region from the movement when such a hidden component is called.

  The scroll area is an example of a display object included in the content, and includes a plurality of other display objects (hereinafter, referred to as “components” for convenience) arranged in the vertical or horizontal direction within the display range. Each component has a feature that reminds the user of some relevance, for example, having a display range of the same size as each other, or performing display related to content.

  These components included in the scroll region operate in conjunction with each other so as to perform a scroll operation (in other words, a slide operation) in response to an input of a key event such as a user operation.

  For example, a description will be given with reference to the example shown in FIG. FIG. 4A illustrates a scroll region 220 that includes four components of item A221, item B222, item C223, and item D224 within the display range. In the state shown in FIG. 4A, the item B222 is focused (in other words, selected).

  In the state shown in FIG. 4A, when a key event designating the bottom is input twice, in the content displayed on the display screen 200, the cursor indicating the selected item moves to the item D224 that is two down. The state shown in FIG. 4B is obtained. In the state shown in FIG. 4B, the item D224 arranged two items below the item B222 is focused.

  In the state shown in FIG. 4B, when a key event designating a further downward direction is input once, in the content displayed on the display screen 200, the uppermost item A221 in the scroll area 220 is the item B222. In addition, the item B222 is replaced with the item C223, the item C223 is replaced with the item D224, and the item D224 is replaced with the new item E225 that has not been displayed so far, and the state shown in FIG. According to the operation, for the user, the uppermost item A221 in the scroll area 220 is hidden at the upper part of the scroll area, and the items B222 to D224 are slid upward one by one, at the lowermost part, at the lower part of the scroll area. It seems that a so-called scrolling operation has been performed in which the hidden item D225 has appeared. For example, for each item, the above-described scroll operation may be performed by simply changing the display content, or the scroll operation may be performed with an animation or the like in which the corresponding part is actually scrolling.

  There may be an example of a scroll area having only one component within the display range. In such an example, the scroll area has only one item that can be visually recognized by the user (in other words, a display item), and the display item is changed to another item by a scroll operation according to the input of the key event. Switch to

  Note that in general content, the user also operates the scroll area via keys provided in the controller 142.

  In order to select each item in the scroll area, the user not only selects the component, but also performs an operation such as calling it in the screen by scrolling the item temporarily hidden outside the visible area. Do. At this time, compared to the operation of selecting a so-called button-like display object that is another non-scroll area, there are many operations required for the user, and whether or not it is a scroll area until it is actually operated. There is a possibility that the operability is felt to be bad for various reasons, for example, when the user does not understand.

  Therefore, if such a scroll area 220 can be detected and the contents of the components included in the scroll area 220 can be analyzed, it is possible to provide an operation method other than the conventional direction designation. Thus, the user operability can be improved. Some contents include information that defines a scroll area in a predetermined format, and the data broadcast receiving apparatus 100 may be able to suitably detect and analyze the scroll area. May not have the right information.

  Hereinafter, an operation for performing detection and analysis of such a scroll area even when the scroll area cannot be easily detected from information included in the content will be described below.

(2) First Operation Example A first operation example of the information processing apparatus 100 will be described with reference to FIGS. 5 and 6. FIG. 5 is a schematic diagram illustrating the operation of each unit according to the first operation example. FIG. 6 is a flowchart showing an operation flow of the change information analysis unit 125 in the first operation example. In FIG. 5, the same components as those shown in FIG. 2 are denoted by the same reference numerals, and the description of the components that are not related to the first operation example is omitted.

  According to the first operation example, the change information analysis unit 125 performs the change when the display content of the content by the display processing unit 122 is changed according to the key event input by the key event input unit 124. By analyzing, a scroll area in the content is detected.

  As illustrated in FIG. 6, in the first operation example, the display processing unit 122 executes the content acquired when the content is displayed on the display 141. The change information analysis unit 125 acquires display information of content input from the display processing unit 122 (step S101).

  The change information analysis unit 125 inputs, to the key event input unit 124, a key event input instruction for virtually inputting a user operation for the displayed content (step S102). The key event input unit 124 inputs a key event to the display processing unit 122 in response to a key event input instruction.

  In the display processing unit 122, the display mode of the content displayed on the display 141 in accordance with the input key event is virtually changed, for example. The change information analysis unit 125 receives display change information indicating the display change at this time (step S103).

  The display change information indicates information indicating a change caused by an operation corresponding to a key event for each display object included in the content. For example, for a display object included in the content, when the display content of the display object is changed by inputting a key event, one display change information is generated for the change corresponding to the display object.

  By the way, in the scroll display area in which the scroll operation is performed, when the display item scroll operation occurs in the display window, the display positions or display contents of the plurality of display items change simultaneously. For example, in a scroll area that scrolls up and down, display items displayed in the display window simultaneously move in one direction. In addition, the display item closest to the end of the display window in the direction of the movement destination moves out of the display window or disappears from the display window. On the other hand, a new display item moves from the outside of the display window into the display window or appears in the display window at a position closest to the end of the display window in the movement source direction.

  When the change information analysis unit 125 receives display change information in which the display of a plurality of display objects is changed at the same time by the input of a key event, the change information analysis unit 125 is related to the scroll operation for the display objects including the plurality of display objects. Judge that there is.

  Subsequently, the change information analysis unit 125 stores the display change information determined to be related to the scroll operation (step S105). The change information analysis unit 125 determines whether or not the stored display change information satisfies a condition that defines the scroll area (step S106).

  The conditions defined for the scroll area are examples of conditions for determining whether or not the display object related to the display change information is the scroll area.

For example, a plurality of other display objects (described as components for convenience) are included in the display range, each component has the same display range on the display screen, and is arranged in a line in the vertical or horizontal direction. The displayed object may be a scroll area. In such a display object, when the display content of each component changes so as to scroll in response to an input of a key event that specifies the arrangement direction of the upper, lower, left and right components, the display object is displayed in the scroll area. It can be judged that there is. Therefore, the condition for the display change information expressing such an operation is an example of the condition for the scroll area.
At this time, in the display object including the display range of these components, the number of components included in the display region is the number of display items in the scroll region that is always visible to the user in the scroll region. In addition, when only one component is included in the display range of the display object and the display content of the component changes according to the input of the key event, the display object is displayed to be visible to the user. It can be determined that this is a scroll area where the number of items is 1.

  Note that the scroll region typically operates such that each component scrolls (in other words, slides) within the display region in response to a user operation, in other words, an input of a key event. Therefore, a condition that allows such an operation to be preferably classified as another operation may be employed as an example of a condition that defines the scroll region.

  The conditions for defining such a scroll area may be stored in the memory 130, for example, and referred to as appropriate for use in the determination.

  When it is determined that the display change information satisfies the conditions specified for the scroll area (step S107: Yes), the change information analysis unit 125 determines that the display object related to the scroll area is the scroll area based on the display change information. To do. Then, the change information analysis unit 125 inputs information related to the display object to the scroll information storage unit 127 as scroll region information (step S108).

  On the other hand, when it is determined that the display change information does not satisfy the conditions specified for the scroll region (step S107: No), the change information analysis unit 125 pays attention to the display object related to the display change information as the scroll region candidate. May be. In this way, the display object attracting attention as a scroll region candidate could not be determined as a scroll region based on the display change information, but based on other determination methods described later, it can be determined whether or not it is a scroll region. There is a possibility that it can be determined accurately.

  As described above, according to the operation according to the first operation example, the scroll area included in the content can be detected based on the change in the display content on the display screen in response to the input of the key event.

  For example, when the key information is input, the change information analysis unit 125 can detect all the constituent elements included in the scroll region by continuously inputting the key event designating the same direction. I can do it. According to this method, the number of components hidden outside the display range (in other words, the range visible to the user) in the scroll region can be detected. In addition, it is possible to specify a component that is noticed in the initial state in the scroll region. Specifically, when a component in a certain display object slides one by one on the display screen in response to an input of a key event, the display object is detected as a scroll area. At this time, the number of display items included in the scroll area is a number obtained by adding 1 to the number of visible display items. Further, when the same key event is continuously input, when the same display change information as when the scroll area is detected is obtained, the number of display items included in the scroll area is a number obtained by adding one by one. If the same display change information cannot be obtained when the same key event is input, it can be determined that the display item is not hidden in the direction of the input e-event. Therefore, the number of display items in all directions can be obtained by repeating the input of a key event designating another direction.

  Even when display change information is obtained, the contents of display items in the scroll area detected so far are compared with each other to determine whether or not a display item that has already been detected appears again. Can be distinguished. For this reason, it is possible to accurately detect the number of display items even in a scroll region where the arrangement of display items is arranged in a loop.

(3) Second Operation Example A second operation example of the information processing apparatus 100 will be described with reference to FIGS. 7 and 8. FIG. 7 is a schematic diagram illustrating the operation of each unit according to the second operation example. FIG. 8 is a flowchart showing an operation flow of the content analysis unit 123 in the second operation example. In FIG. 7, the same components as those shown in FIG. 2 are denoted by the same reference numerals, and the description of the components that are not related to the second operation example is omitted.

  According to the second operation example, the content analysis unit 123 analyzes the content data (for example, the content source described in the BML language) that constitutes the content acquired by the content acquisition unit 121, thereby The scroll area included in is detected.

  As shown in FIG. 7, content data about the content acquired by the content acquisition unit 121 is input to the display processing unit 122 and the content analysis unit 123. The display processing unit 122 displays content on the display 141 based on the received content data.

  As shown in FIG. 8, the content analysis unit 123 reads the received content data (step S201), and detects a key event handler included in the content (step S202). The key event handler is information included in the content data, and describes processing according to a key event input to the content.

  Next, the content analysis unit 123 analyzes the key event handler to detect an element (in other words, a display object) whose display content on the display screen 200 is changed by processing according to the input key event. (Step S203). Then, the content analysis unit 123 determines whether or not the detected element satisfies the condition of the scroll area (step S204). The scroll area condition used here refers to a display object whose display content is changed by the input of a key event, as in the condition used for determining the scroll area based on the display change information according to the first operation example described above. In this condition, it can be determined whether or not the change corresponds to a scroll operation.

  The content analysis unit 123 determines that an element satisfying such a condition is a component of the scroll region, and inputs information about a display object including the element to the scroll information storage unit 127 as scroll region information (step S205). ).

  As described above, according to the operation according to the second operation example described above, the content data defining the content is analyzed by the operation of the content analysis unit 123, and the scroll area included in the content is detected. Note that, for example, in a WEB content or the like, a scroll area may be defined by a description according to a predetermined format in content data. In general, by referring to the description, the device that processes the content can grasp the presence / absence, display range, display items, and the like of the scroll area in the content.

  On the other hand, according to the second operation example of the data broadcast receiving apparatus 100, even when there is no description relating to the scroll area defined in such a format, the display change mode according to the input of the key event Thus, the scroll area can be detected. For this reason, the scroll area included in the content that is not defined in a predetermined format for the scroll area can be suitably detected. Therefore, it is advantageous in terms of versatility compared with a processing device that detects a scroll area based on such a format.

(4) Third Operation Example A third operation example of the information processing apparatus 100 will be described with reference to FIGS. 9 and 10. FIG. 9 is a schematic diagram illustrating the operation of each unit according to the third operation example. FIG. 10 is a flowchart showing an operation flow of the display information analysis unit 126 in the third operation example. In FIG. 9, the same components as those shown in FIG. 2 are denoted by the same reference numerals, and the description of the components that are not related to the third operation example is omitted.

  According to the third operation example, the display information analysis unit 126 detects a scroll area included in the content based on the display image and layout of the content displayed on the display screen 200.

  As shown in FIG. 9, the display processing unit 122 outputs the received content data to the display 141, and displays the display information indicating the display contents of the content data and the arrangement of the display objects included in the content data. Layout information indicating the state is input to the display information analysis unit 126. The display information analysis unit 126 analyzes the display information and the layout information, and detects a scroll area included in the content.

Specifically, as shown in FIG. 10, the display processing unit 122.
As shown in FIG. 8, the content processing unit 122 reads the received content data, extracts display information and layout information (step S301), and inputs them to the display information analysis unit 126 (steps S302 and S305). .

  As a first operation, the display information analysis unit 126 analyzes the received display information and determines whether or not there is a display object corresponding to the scroll area in the content (step S303). When the scroll area is detected (step S303: Yes), the display information analysis unit 126 inputs the scroll area information related to the scroll area to the scroll information storage unit 127 (step S304).

  As a second operation, the display information analysis unit 126 analyzes the received layout information and determines whether or not there is a display object corresponding to the scroll area in the content (step S306). When the scroll area is detected (step S306: Yes), the display information analysis unit 126 inputs the scroll area information related to the scroll area to the scroll information storage unit 127 (step S307).

  The first operation and the second operation described above may be performed simultaneously, or may be performed in succession in any order. In addition, when the scroll region is detected by either the first operation or the second operation, the other operation may be stopped and the operation may be terminated.

  Here, an example of a method for detecting a scroll region based on content display information or layout information will be described.

  The scroll area is generally displayed as a display object that is arranged in the vertical or horizontal direction and includes a plurality of display objects (in other words, constituent elements) each having a similar display range. For example, the display object 220 described with reference to FIG. 4A and including a plurality of components (that is, item A221, item B222, item C223, and item D224) within the display range is a typical example. As described above, the display object that is the scroll area has a display content or a layout feature that can be recalled to the user to perform a scroll operation. Accordingly, by paying attention to such a feature, the display image analysis unit 126 can suitably detect the scroll region.

  Further, as shown in FIG. 4D, the components included in the scroll area 220 (that is, the item A221, the item B222, the item C223, and the item D224) are scrolled adjacent to the scroll area 220. A scroll bar 226 may be arranged. Such a scroll bar 226 is, for example, a display object that indicates a mode of a scroll operation in the scroll region 220 or directly controls the scroll operation in the scroll region 220 in accordance with a user operation. By detecting such a scroll bar 226 by a method such as pattern matching, for example, the display image analysis unit 126 can more suitably detect a scroll area included in the content.

  As described above, according to the third operation example, the display image analysis unit 126 preferably detects the scroll area included in the content based on the display content and layout of the content displayed on the display screen 200. Is possible. For this reason, for example, in the content data that defines the content, it is possible to suitably detect a scroll region that performs a scroll operation that is not defined in a predetermined format.

  As described above, according to the first to third operation examples described above, the scroll area included in the content can be detected based on different determination criteria. It should be noted that the operations shown in the respective operation examples can detect the scroll area by being executed independently, but may be executed by combining a part or all of one content. When executed in this manner, it is possible to detect a scroll area included in the content with higher accuracy.

  In the above-described example, the data broadcast receiving apparatus 100 that handles content described in a markup language for digital data broadcasting such as BML has been described as a specific example of the information processing apparatus of the present invention. However, the present invention is not limited to this aspect, and the above-described object and processing corresponding to the object are defined, and content that can be operated using a pointing device may be handled as an example of the content of the present invention. An information processing apparatus such as a car navigation apparatus, a smartphone, or a personal computer that processes such content can also be a specific example of the information processing apparatus of the present invention.
