  The operation and other advantages of the present invention will become apparent from the embodiments described below.

  Hereinafter, as the best mode for carrying out the invention, description will be given of an embodiment according to an information processing apparatus and method and a computer program of the present invention.

(Embodiment of information processing apparatus)
Embodiments according to the information processing apparatus of the present invention acquire content that independently includes object information indicating at least one drawing object and script information indicating a processing script that defines processing for the at least one drawing object. An acquisition unit; an output unit that outputs the content to a display unit that displays the content on a display screen; and at least one of the at least one drawing object based on at least one of the object information and the script information Based on at least one of the object information and the script information, a display position of the operation target object on the display screen based on first operation means that detects an operation target object that is a drawing object to be operated by the user Detect Second detection means for detecting, based on at least one of the object information and the script information, third detection means for detecting a process executed when the user's operation is performed on the operation target object; Generating means for generating a processing database in which the operation target object and a process executed when the user's operation is performed on the operation target object are associated with each other; and a desired database on the display screen When the user specifies the display position of the operation target object using a pointing device that can specify a display position, the user's operation target object specified by the user is determined based on the processing database. Processing means for executing processing to be executed when an operation is performed.

  In the embodiment of the information processing apparatus of the present invention, the content is acquired by the operation of the acquisition unit. The acquired content is output to the display means by the operation of the output means. The output means may directly output the content to the display means as data in a format that can be directly processed by the display means. Alternatively, the output unit may output the content as data of a predetermined format to an arbitrary processing unit (particularly, an external or internal processing unit provided between the output unit and the display unit). In this case, in the processing means, the content is converted into data in a format that can be directly processed by the display means, and then output to the display means. In other words, the output means may output the content indirectly to the display means as data that becomes data in a format that can be directly processed by the display means by performing a predetermined process. As a result, it is displayed on the display screen by the operation of the display means. Here, “content” in the present embodiment includes object information and script information. The “object information” in the present embodiment is information indicating at least one drawing object that is actually displayed (in other words, drawn) on the display screen. For example, the type, display position, and image of the drawing object are displayed. Show. Further, “script information” in the present embodiment is information indicating processing executed in response to a predetermined operation on the drawing object, and indicates, for example, a script itself that defines the processing. Particularly, in the “content” according to the present embodiment, the object information and the script information are described in a clearly separated state. An example of such content is data broadcast content that is broadcast on BS digital broadcast or terrestrial digital broadcast, for example. In this case, the content is described in BML including ECMAScript. Of course, the “content” in the present embodiment is not limited to the data broadcast content, and is displayed on the display screen as object information (in other words, information indicating the drawing object itself on the display screen) and script information (in other words, displayed on the display screen). If the content is described in a state in which the information indicating the processing itself performed on the drawn object is separated, it can be an example of the content according to the present embodiment.

  Such content (typically data broadcasting content) is designed on the premise of operation using a remote controller. However, in the present embodiment, an intuitive operation using a pointing device such as a touch panel, a mouse, a tablet, or a touch pad is provided for such content.

  In order to provide such an intuitive operation, in the present embodiment, an operation target object that is a drawing object to be operated by the user among at least one drawing object indicated by the object information by the operation of the first detection unit. Is detected. Here, the “operation target object to be operated” refers to a drawing object that is a target of some action by an operation using the remote controller. For example, a focus indicating a state currently focused on by the user is shown. A drawing object that can be changed and a drawing object that can be selected (in other words, executable) are shown. Needless to say, when there are a plurality of operation target objects, a plurality of operation target objects are detected.

  Further, the display position (or display coordinates) of the operation target object detected by the first detection unit on the display screen is detected by the operation of the second detection unit. Needless to say, when there are a plurality of operation target objects, the display positions of the plurality of operation target objects are detected.

  In addition, processing executed when a user operation is performed on the operation target object is detected by the operation of the third detection unit. Specifically, for example, a process that is executed when the focus shifts to the operation target object and a process that is executed when the operation target object is selected are detected. Here, it is preferable that a process executed by each of all operations that can be performed on the operation target object is detected. In addition, when there are a plurality of operation target objects, it goes without saying that a process executed when a user operation is performed is detected for each of the plurality of operation target objects.

  Thereafter, an operation target object (that is, a detection result by the first detection unit) and processing executed when a user operation is performed on the operation target object (that is, the third detection) by the operation of the generation unit. A processing database associated with the detection result by the means is generated. Specifically, for example, the first operation target object is associated with a process executed when a user operation is performed on the first operation target object, and the first operation target object A processing database that associates different second operation target objects with processing executed when a user operation is performed on the second operation target objects is generated.

  After or in parallel with the processing described above, a user operation using the pointing device is performed on the content displayed on the display screen. Here, when the position designated by the user matches or is included in the display position of the operation target object detected by the second detection means, the user's operation (for example, selection operation or determination operation) on the operation target object. Is recognized as having been done. In this case, the processing to be executed when the focus is shifted or selected with respect to the operation target object designated by the user is performed by referring to the processing database by the operation of the processing means.

  As a result, for example, an operation using a pointing device can be performed on content designed on the assumption of an operation using a remote controller. In particular, an association between an operation target object (that is, an element specified by object information) and a process executed by an operation performed on the operation target object (that is, an element specified by script information) is shown. Since the processing database is generated, the operation using the pointing device can be realized even for the content described using the script program. This is extremely excellent in that it cannot be enjoyed with the configurations disclosed in Patent Documents 1 and 2 that realize an operation using a pointing device by using navigation characteristics.

  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). Alternatively, 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 third detecting unit selects a direction key for performing a moving operation for moving a focus on the operation target object and a selection operation for selecting the operation target object. This is executed when the user performs an operation on the operation target object by performing a pseudo or virtual operation on the content using an operation unit having a determination key for performing Detect processing.

  According to this aspect, it is possible to reliably detect the process executed when the user performs an operation on the operation target object.

  In this case, it is preferable that all operations that can be assumed are executed in a pseudo or virtual manner. As a result, it is possible to reliably detect all of the processes executed when an operation that can be assumed is performed on all the operation target objects.

  Note that “performing a pseudo or virtual operation” means, for example, that an operation is performed on a CPU or the like, and it is necessary to reflect the operation result in the display mode on the operation display screen. Absent. Specifically, for example, an operation such as a simulation is performed.

  In the aspect of the information processing apparatus that performs the operation on the content using the operation unit in a pseudo or virtual manner as described above, the third detection unit moves the movement with respect to a state in which the operation target object is selected. It may be configured to detect at least one of processing executed when an operation is performed and processing executed when the selection operation is performed on a state where the operation target object has a focus. Good.

  According to this configuration, it is possible to suitably detect, for each operation target object, a movement destination when the movement operation is performed, a process performed along with the movement operation, a process when the selection operation is performed, and the like.

  In another aspect of the embodiment of the information processing apparatus of the present invention, the generation unit selects the operation target object, a process to be executed when the operation target object is selected, and the operation target object. Each of the processes to be executed before is generated, and the processing means adds to the process to be executed when selecting the operation target object specified by the user Then, a process to be executed until the operation target object designated by the user is selected is further performed.

  Even if a drawing object can be directly specified by an operation using a pointing device, there is a drawing object that can only be moved after the focus is moved to another drawing object by an operation using the remote control. . For example, when the focus is shifted to the drawing object located at the bottom in the state where the drawing object located at the top of the three drawing objects continuously arranged in the vertical direction has the focus, the remote control is first It is necessary to shift the focus to the drawing object positioned at the center by pressing the lower key of the direction key included in the image, and then shift the focus to the drawing object positioned at the bottom by pressing the lower key again. Here, the process executed when the focus is shifted to the drawing object located at the bottom is the process premised on the process executed when the focus is changed to the drawing object located at the center. In this case, when the focus is directly shifted to the drawing object positioned at the bottom using the pointing device, there is a possibility that the originally intended process may not be performed. In other words, when the focus is transferred directly to one drawing object using a pointing device, the original operation is not performed until the focus is changed to that one drawing object. Processing that is executed when the focus is changed and that should be executed before the focus is changed to one drawing object may not be properly performed. .

  However, according to this aspect, the processing database includes not only the processing executed when the focus is shifted to one drawing object but also the processing that should be executed before the focus is shifted to one drawing object. Can be generated. Therefore, even when the focus is directly shifted to one drawing object using the pointing device, the process is executed when the focus is changed to one drawing object and the focus is set to one drawing object. It is possible to appropriately perform a process based on a process that should be executed before the transition.

  In another aspect of the embodiment of the information processing apparatus according to the present invention, the generation unit performs the processing to be executed before each of the operation target objects and the operation target object are selected. The processing database in which processing to be executed when selecting an operation target object is associated with each other is generated, and the processing means is executed until the operation target object designated by the user is selected. A process to be executed when the operation target object designated by the user is selected after the process to be performed is performed.

  According to this aspect, as described above, not only the process executed when the focus is shifted to one drawing object, but also the process that should be executed before the focus is shifted to one drawing object. A processing database can be generated. In particular, as a process executed when the focus is shifted to one drawing object, a processing database including a process that takes into account a process that should be executed until the focus is shifted to one drawing object is generated. . Therefore, even when the focus is directly shifted to one drawing object using the pointing device, the process is executed when the focus is changed to one drawing object and the focus is set to one drawing object. It is possible to appropriately perform a process based on a process that should be executed before the transition.

  In these aspects, the process to be executed until the operation target object is selected may be configured to include at least a personal profile indicating the attribute of the user.

  According to this configuration, even when the focus is directly shifted to one drawing object using the pointing device, the process is executed when the focus is shifted to one drawing object. It is possible to appropriately perform processing based on processing using a personal profile that should be executed before the focus is shifted to the drawing object.

  In another aspect of the embodiment of the information processing apparatus of the present invention, the content is data broadcast content.

  According to this aspect, for example, the above-described various effects can be suitably enjoyed for data broadcast content that is broadcast superimposed on BS digital broadcast or terrestrial digital broadcast.

  As described above, in the aspect of the information processing apparatus in which the content is data broadcast content, each of the object information and the script information may be configured to be described in an A profile of BML (Broadcast Markup Language).

  According to this aspect, for example, the various effects described above can be favorably received for data broadcast contents described using BML including ECMAScript.

(Embodiment of information processing method)

Of the at least one drawing object, an acquisition step, an output step of outputting the content to a display means for displaying the content on a display screen, and at least one of the object information and the script information Based on at least one of the object information and the script information, a display position of the operation target object on the display screen based on a first detection step of detecting an operation target object that is a drawing object to be operated by the user Detect A second detection step, and a third detection step for detecting processing executed when the user's operation is performed on the operation target object based on at least one of the object information and the script information; Generating a process database in which the operation target object and the process executed when the user performs an operation on the operation target object are associated with each other; and a desired process on the display screen When the user specifies the display position of the operation target object using a pointing device that can specify a display position, the user's operation target object specified by the user is determined based on the processing database. And a processing step for executing processing to be executed when an operation is performed.

  According to the embodiment of the information processing method of the present invention, it is possible to receive the same effects as the various effects that can be enjoyed by the above-described embodiment of the information processing apparatus of the present invention.

Therefore, an operation using a pointing device can be realized for various contents such as data broadcast contents described using a script program.

  Embodiments of the present invention will be described below with reference to the drawings. In the following embodiments, an example in which the information processing apparatus according to the present invention is applied to a data broadcast receiving apparatus capable of receiving and displaying data broadcast contents will be described.

(1) Basic Configuration First, the basic configuration of the data broadcast receiving apparatus 1 according to the present embodiment will be described with reference to FIG.

  The receiving unit 11 constitutes a specific example of “acquiring means” in the present invention, and is configured to receive broadcast radio waves and to acquire data broadcast contents included in the broadcast radio waves. In addition to the data broadcast content, normal broadcast content may be acquired. In this case, the program of the channel selected by the user in the broadcast content is displayed on the display 14.

  In this embodiment, it is assumed that the data broadcast content is described in BML and conforms to the A profile. Of course, it goes without saying that other data broadcast contents may be used.

  The BML interpretation / execution unit 12 constitutes a specific example of the “processing means” in the present invention, and is configured to interpret and execute BML data describing data broadcast content. Further, the BML interpretation / execution unit 12 is configured to be able to execute processing corresponding to a user operation using the pointing device 17 extracted by the input response analysis / control unit 15. The execution result (that is, the display instruction of the data broadcast content) is output to the display processing unit 13.

  The display processing unit 13 constitutes a specific example of the “output unit” in the present invention, and the display 14 can be controlled so as to display the data broadcast content according to the execution result in the BML interpretation / execution unit 12. It is configured.

  The display 14 constitutes a specific example of “display means” in the present invention, and displays data broadcast content under the control of the display processing unit 13. Examples of such a display 14 include a liquid crystal display, a plasma display, a cathode ray tube display, an organic EL display, and the like.

  The data broadcast receiving apparatus 1 may be configured not to include the display 14. In this case, by using an external display connected to the data broadcast receiving apparatus 1, processing described later can be performed.

  The input response / analysis control unit 15 constitutes specific examples of “first detection means”, “second detection means”, “third detection means”, and “generation means” in the present invention, and includes direction keys, It is analyzed how the data broadcast content acquired in the receiving unit 11 is operated and executed by an operation using a remote controller having at least a determination key. The analysis result is stored in the database storage unit 16 as a processing database. Further, the input response / analysis control unit 15 detects a user operation using the pointing device 17 and extracts a process corresponding to the user operation from the processing database. Thereafter, the BML interpretation / execution unit 12 is controlled to perform the extracted process. A more detailed description of the input response / analysis control unit 15 will be described later in detail with specific examples (see FIG. 3 and the like).

  The database storage unit 16 is configured to be able to store the processing database generated in the input response / analysis control unit 15.

  The data bus 20 is used when data is input / output between the constituent elements of the data broadcast receiving apparatus 1.

(2) Operation Principle Next, with reference to FIG. 2, the operation principle of the data broadcast receiving apparatus 1 according to the present embodiment will be described. FIG. 2 is a flowchart conceptually showing a flow of operations of the data broadcast receiving apparatus 1 according to this embodiment. For simplification and clarification of the explanation, FIG. 2 briefly describes the operation flow of the data broadcast receiving apparatus 1 according to the present embodiment, and the detailed mode thereof will be described later with a display example. This will be described (see FIGS. 3 to 6).

  As shown in FIG. 2, first, the data broadcast content is acquired by the operation of the receiving unit 11 (step S101). The acquired data broadcast content is displayed on the display screen of the display 14.

  Subsequently, by analyzing the BML data describing the data broadcast content acquired in step S101 by the operation of the input response / analysis control unit 15, a drawing object (in other words, a display component) included in the data broadcast content is obtained. It is detected (step S102). The detection operation here is performed by referring to a BML element (div element, object element, p element, etc., which will be described in detail later) in the BML data. At this time, the display position (in other words, display coordinates) of the drawing object on the display screen of the display 14 may be detected.

  Subsequently, the position of the initial focus is detected by analyzing the BML data describing the data broadcast content acquired in step S101 by the operation of the input response / analysis control unit 15 (step S103). That is, the default focus position when the data broadcast content is displayed for the first time is detected. Note that “focus” indicates a drawing object currently focused by the user among drawing objects included in the data broadcast content. In this case, it is preferable to display the highlighted drawing object so that it is distinguished from the drawing object that does not have the focus, or it is configured to be highlighted by the processing of the data broadcasting content itself. May be.

  Subsequently, the operation of the input response / analysis control unit 15 analyzes the BML data describing the data broadcast content acquired in step S101, thereby inputting an operation key (for example, a direction key or a determination key) provided in the remote controller. The element and the handler that receive are detected (step S104).

  Subsequently, the operation of the input response / analysis control unit 15 analyzes the BML data describing the data broadcast content acquired in step S101, and can be operated by the user (in other words, the focus can be moved or selected). A drawing object that can be executed is detected (step S105). At the same time, the display position (in other words, display coordinates) of the drawing object that can be operated by the user on the display screen of the display 14 is detected. In the following description, for the sake of simplicity, the drawing object that can be operated by the user will be referred to as an “operable drawing object”.

  Subsequently, the operation of the input response / analysis control unit 15 analyzes the BML data describing the data broadcast content acquired in step S101, and thereby controls the operable drawing object detected in step S105 with a remote controller (for example, , A process executed by performing an operation using a remote controller including at least a direction key and an enter key is detected (step S106). Here, it is not necessary to actually perform an operation and execute a process, and it is sufficient to perform an operation using a remote controller virtually or in a pseudo manner and detect a process executed as a result of the operation.

  Subsequently, the operation of the input response / analysis control unit 15 associates the operable drawing object with the processing executed by performing the operation on the operable drawing object based on the detection result in step S107. The processing database shown is generated (step S107). The processing database generated in step S107 is stored in the database storage unit 16.

  Subsequently, whether or not a user operation using the pointing device 17 is performed is detected by the operation of the input response / analysis control unit 15 (step S108).

  When a user operation using the pointing device 17 is performed, it is determined whether or not an operable drawing object is displayed at a position on the display screen designated by the user using the pointing device 17. In other words, it is determined whether or not the position on the display screen designated by the user using the pointing device 17 matches the display position of the operable drawing object detected in step S105.

  When the operable drawing object is not displayed at the position on the display screen designated by the user using the pointing device 17 (that is, the position on the display screen designated by the user using the pointing device 17 and the step S105). If the detected display position of the operable drawing object does not match, no special processing is performed.

  On the other hand, when the operable drawing object is displayed at the position on the display screen designated by the user using the pointing device 17 (that is, the position on the display screen designated by the user using the pointing device 17; In the case where the display position of the operable drawing object detected in step S105 matches, the processing database stored in the database storage unit 16 is referred to by the operation of the input response / analysis control unit 15, and the pointing device The process executed when an operation is performed on the operable drawing object displayed at the position on the display screen designated by the user using 17 is extracted. Thereafter, the operation of the input response / analysis control unit 15 controls the BML interpretation / execution unit 12 so that the extracted processing is executed. As a result, processing according to the user's operation using the pointing device 17 is performed (step S109).

(3) Specific Example Next, with reference to FIG. 3 to FIG. 6, a specific processing mode will be described with a specific display example. FIG. 3 is a plan view conceptually showing a display example of the data broadcast content, FIG. 4 is a data structure diagram conceptually showing the processing database, and FIG. 5 is a data broadcast shown in FIG. FIG. 6 is a plan view conceptually showing a display example when a weather button is designated for a content using the pointing device 17, and FIG. 6 uses the pointing device 17 for the data broadcast content shown in FIG. 6 is a plan view conceptually showing a display example when a stock price button is designated.

  As shown in FIG. 3, a specific example of the data broadcast content includes a broadcast station logo 101, a television video display column 102 in which normal broadcast content is displayed, an information display column 103, and a news button 104 as drawing objects. And a weather button 105 and a stock price button 106. These drawing objects are arranged on the background 110.

  Further, in one specific example of the data broadcast content, the focus exists on any of the news button 104, the weather button 105, and the stock price button 106. That is, the news button 104, the weather button 105, and the stock price button 106 are operable drawing objects. On the other hand, the broadcast station logo 101, the television image 102, and the information display field 103 are not operable drawing objects because the focus does not change.

  When the data broadcasting content is displayed for the first time, the focus is on the news button 104. When the focus is on the news button 104, news is displayed in the information display field 103. In the state where the focus is on the news button 104, when the up key, the left key, or the right key among the direction keys of the remote control is pressed, the focus transition does not occur. On the other hand, when the down key of the direction keys of the remote controller is pressed while the focus is on the news button 104, the focus changes from the news button 104 to the weather button 105. Further, when the determination key of the remote controller is pressed while the focus is on the news button 104, the news content is displayed on at least a part or the whole of the information display field 103 or the display screen of the display 14.

  When the focus is on the weather button 105, the weather forecast is displayed in the information display field 103. At this time, when the focus changes from the news button 104 to the weather button 105, the user profile information is read from the permanent storage area in the memory 20 of the data broadcast receiving apparatus 1 and set in the variable userdata. Then, the weather forecast information is read according to the information set in the variable userdata. The weather forecast information is set in a variable weatherdata and is recorded in a temporary storage area in the memory 20 of the data broadcast receiving apparatus 1. Therefore, a weather forecast corresponding to the user's profile information (for example, a weather forecast near the address set by the user) is displayed in the information display field 103. In the state where the focus is on the weather button 105, when the left key or the right key among the direction keys of the remote controller is pressed, the focus transition does not occur. On the other hand, when the upper key of the direction keys of the remote controller is pressed while the focus is on the weather button 105, the focus changes from the weather button 105 to the news button 104. Further, when the down key of the direction keys of the remote controller is pressed while the focus is on the weather button 105, the focus changes from the weather button 105 to the stock price button 106. Further, when the determination key of the remote controller is pressed while the focus is on the weather button 105, the weather forecast content is displayed on at least a part of or the entire display screen of the information display field 103 or the display 14. . At this time, since the weather forecast information corresponding to the information set in the variable userdata (that is, the weather forecast corresponding to the profile information) is recorded in the temporary storage area in the memory 20 of the data broadcast receiving device 1, the weather Even when the forecast content is displayed, the weather forecast corresponding to the profile information is continuously displayed.

  In a state where the stock price button 106 is focused, the stock price information is displayed in the information display field 103. At this time, in the information display field 103, stock price information (for example, the user is interested in) according to the user's profile information read when the focus is shifted to the weather button 105 (that is, set in the variable userdata). Stock price information). This stock price information is set in a variable stockdata and recorded in a temporary storage area in the memory 20 of the data broadcast receiving apparatus 1. If the down key, left key, or right key among the direction keys of the remote controller is pressed while the stock price button 106 has focus, focus transition does not occur. On the other hand, when the up key of the direction keys of the remote control is pressed while the stock price button 106 is in focus, the focus changes from the stock price button 106 to the weather button 105. Further, when the determination key of the remote control is pressed while the stock price button 106 is in focus, the stock price information content is displayed on at least a part of or the entire display screen of the information display field 103 or the display 14. . At this time, stock price information corresponding to the information set in the variable userdata (that is, stock price information corresponding to the profile information) is recorded in the temporary storage area in the memory 20 of the data broadcast receiving apparatus 1. Even when the content is displayed, the stock price information corresponding to the profile information is continuously displayed.

  A specific example of such data broadcasting content is described as the following BML data. In particular, in the BML data, a definition part that defines a script and a definition part that defines a drawing object are described separately and independently.

------------ End of BML data ----------
The data broadcast receiving apparatus 1 according to the present embodiment analyzes such BML data (from step S102 to step S106 in FIG. 2), so that an operable drawing object and an operation on the operable drawing object are performed. A processing database indicating the association with the processing executed in step 1 is generated.

  Specifically, first, a drawing object is detected (see step S102 in FIG. 2). Here, a BML element (specifically, for example, a div element, an object element, a p element, etc.) in the BML data is detected as a drawing object. As a result, the broadcast station logo 101, the TV image display field 102 on which normal broadcast content is displayed, the information display field 103, the news button 104, the weather button 105, the stock price button 106, and the background 110, Detected as a drawing object.

  Subsequently, the position of the initial focus when the data broadcast content is read (in other words, when it is displayed) is detected (see step S103 in FIG. 2). Here, in BML, focus is set using a method using a focus () function for a drawing object or a navigation characteristic (nav-index), and the execution timing is defined by a script definition (specifically, This is performed at a timing determined in the function assigned to the global area in the above-mentioned BML data (the BML data in a portion surrounded by <script> and </ script>) and the onload attribute of the body element.

  In the BML data described above, the navigation characteristic is not used, and the onload function assigned to the body attribute is executed. In the onload function, the focus () function is executed for the background 110 (that is, the div element whose id attribute is docbody). Therefore, it can be seen that the initial focus is on the background 110.

  Subsequently, an element and a handler that receive an input of an operation key (for example, a direction key or a determination key) provided in the remote controller are detected (see step S104 in FIG. 2). Here, the event corresponding to the operation key provided in the remote controller is a predetermined attribute such as an onkeydown attribute, an onkeyup attribute, or an onclick attribute declared for the BML element defined in the BML data describing the data broadcasting content. Processed by assigned function.

  In the BML data described above, the onkeydown attribute is declared only for the background 110 (that is, the div element whose id attribute is docbody), and therefore all the input of the operation keys provided in the remote control are assigned to the onkeydown attribute. It is detected that the data is processed by the keyDown () function.

  Subsequently, the operable drawing object and its display position are detected (see step S105 in FIG. 2), and a process executed by performing an operation using the remote control on the operable drawing object is detected. (Step S106 in FIG. 2). Here, since it has already been detected that all the processes for the input of the operation keys provided in the remote control are processed by the keydown () function, various input operations (in other words, all possible operations can be performed on this function). ), The operation using the operation keys provided in the remote controller is performed in a pseudo or virtual manner. By performing this pseudo or virtual operation, it becomes clear how the focus changes, so that an operable drawing object can be detected. In addition, the operation using the operation key provided in the remote control is performed in a pseudo or virtual manner, and at the same time, the processing executed in accordance with the operation is analyzed, thereby corresponding to the operation using the operation key provided in the remote control. It is possible to detect a process (in other words, a process executed when the focus is shifted to the operable drawing object or when the operable drawing object is selected).

  As a result, in the BML data described above, it is analyzed that there is no processing for the input of the left key and the right key among the operation keys provided in the remote controller, and the focus is not changed by the operation of the left key and the right key. Also, an image in which each of the news button 104, the weather button 105, and the stock price button 106 has been focused by the input of the left key and the right key of the operation keys provided in the remote control (that is, the highlighted image). Is switched to an image in which the focus has not changed (ie, an image that is not highlighted) or vice versa. Therefore, each of the news button 104, the weather button 105, and the stock price button 106 is detected as an operable drawing object. At this time, the display position of the operable drawing object can also be detected by referring to “top” and “left” in the BML data.

  As the focus changes, the values of the variable focusIndex indicating the ID of the drawing object having the focus, the variable weatherdata indicating the weather forecast information, the variable stockdata indicating the stock price information, and the variable userdata indicating the profile information are appropriately set. Therefore, it is analyzed that these variables influence the processing in the data broadcast content.

  It is also analyzed that pressing the enter key among the operation keys of the remote control causes a transition to a URI according to the value set in the variable focusIndex (that is, the launchDocument () function is executed). The

  As a result of the above analysis, the operable drawing objects are found to be the news button 104, the weather button 105, and the stock price button 106, and when the focus transitions to each of the operable drawing objects, the variable focusIndex, the variable The value to be set for each of the weatherdata, the variable stockdata, and the variable userdata and the process to be executed when each operable drawing object is selected. Subsequently, based on the result of the analysis as described above, a processing database is generated that indicates the correspondence between the operable drawing object and the processing executed by performing an operation on the operable drawing object (see FIG. 2 step S107).

  Specifically, when the focus is shifted to the news button 104 which is one of the operable drawing objects, the variable focusIndex is set to “0”, and when the news button 104 is selected, the variable focusIndex is selected. Transition to a URI (that is, news content) corresponding to the value of is performed. Therefore, as shown in FIG. 4, a record in which the news button 104, the value of the variable index when the focus is changed to the news button 104, and the processing when the news button 104 is selected is associated with the record. A processing database is generated.

  Similarly, when the focus is shifted to the weather button 105, which is one of the operable drawing objects, the variable focusIndex is set to “1”, and the variable userdata is permanently stored in the memory 20 of the data broadcast receiving apparatus 1. The profile information recorded in the area is set, and the value of the variable userdata is set to the variable weatherdata. When the weather button 105 is selected, a transition to a URI (that is, weather forecast content) corresponding to the value of the variable focusIndex is performed, and the value of the variable weatherdata is stored in the memory 20 of the data broadcast receiving device 1. In the temporary storage area. Therefore, as shown in FIG. 4, the weather button 105, the values of the variable focusIndex, the variable weatherdata, and the variable userdata when the focus is changed to the weather button 105, and the processing when the weather button 105 is selected. A processing database including the associated records is generated.

  Similarly, when the focus is shifted to the stock price button 106 which is one of the operable drawing objects, “2” is set to the variable focusIndex, and the variable userdata is stored in the memory 20 of the data broadcast receiving device 1 in a permanent manner. The profile information recorded in the area is set, and the value of the variable userdata is set in the variable stockdata. When the stock price button 106 is selected, a transition to a URI (that is, stock price information content) corresponding to the value of the variable focusIndex is performed, and the value of the variable stockdata is stored in the memory 20 of the data broadcast receiving apparatus 1. In the temporary storage area. Therefore, as shown in FIG. 4, the stock price button 106, the values of the variable focusIndex, the variable stockdata, and the variable userdata when the focus is changed to the weather button 106, and the processing when the stock price button 106 is selected. A processing database including the associated records is generated.

  Thereafter, referring to the database shown in FIG. 4, processing corresponding to the user's operation using the pointing device 17 is executed.

  Specifically, it is assumed that the user designates the weather button 105 from the initial state shown in FIG. 4 using the pointing device 17 as shown in FIG. In FIG. 5, as an example of the pointing device 17, an example is illustrated in which a touch panel 17 a that is disposed on the front surface of the display screen of the display 14 or is integrated with the display screen of the display is used. In this case, the focus is shifted to the weather button 105, and by referring to the processing database, the variable focusIndex is set to “1”, and the variable userdata is recorded in the permanent storage area in the memory 20 of the data broadcast receiving apparatus 1. The set profile information is set, and the value of the variable userdata is set to the variable weatherdata. Further, by referring to the processing database, a transition to a URI (that is, weather forecast content) corresponding to the value of the variable focusIndex is performed, and the value of the variable weatherdata is temporarily stored in the memory 20 of the data broadcast receiving apparatus 1. Recorded in the area.

  At this time, the designation operation of the weather button 105 using the pointing device 17 may be handled as only a movement operation for shifting the focus to the weather button 105. In this case, among the processes described above, the transition to the URI (that is, the weather forecast content) according to the value of the variable focusIndex and the recording of the value of the variable weatherdata in the temporary storage area in the memory 20 of the data broadcast receiving device 1 are performed. Instead, the weather forecast information is displayed in the information display field 103.

  Similarly, assume that the user designates the stock price button 106 from the initial state shown in FIG. 4 using the pointing device 17 as shown in FIG. In this case, “2” is set in the variable focusIndex, the profile information recorded in the permanent storage area in the memory 20 of the data broadcast receiving device 1 is set in the variable userdata, and the value of the variable userdata is set in the variable stockdata. Is set. In addition, a transition to a URI (that is, stock price information content) corresponding to the value of the variable focusIndex is performed, and the value of the variable stockdata is recorded in a temporary storage area in the memory 20 of the data broadcast receiving device 1.

  At this time, the designation operation of the stock price button 106 using the pointing device 17 may be handled as only a movement operation for shifting the focus to the stock price button 106. In this case, among the processes described above, the transition to the URI (that is, the stock price information content) according to the value of the variable focusIndex and the recording of the value of the variable stockdata to the temporary storage area in the memory 20 of the data broadcast receiving device 1 are performed. The stock price information is displayed in the information display field 103 without being performed.

  Here, it is assumed that all operations that can be assumed are not executed in a pseudo or virtual manner and a processing database is not created. That is, processing different from that of the data receiving apparatus according to the present embodiment is performed. At this time, when the focus shifts to the stock price button 106, “2” is set to the variable focusIndex, and the value of the variable userdata is only set to the variable stockdata. This is because the process of setting the profile information recorded in the permanent storage area in the memory 20 of the data broadcast receiving apparatus 1 in the variable userdata is not executed when “focus shifts to the stock price button 106”. This is because it is executed when “focus shifts to the weather button 105”. In this case, since the value of the variable userdata is “null”, an appropriate value is not set in the variable stockdata. As a result, even if the transition to the URI (that is, the stock price information content) corresponding to the value of the variable focusIndex is performed, the stock price information corresponding to the user profile information cannot be displayed.

  However, in the present embodiment, since all possible operations are executed in a pseudo or virtual manner, when the focus changes to the stock price button 106, the focus changes to the weather button 105 before that. It is analyzed that the profile information should be set in the variable userdata. Therefore, the processing database is created so as to include not only a process executed alone when the focus changes to the stock price button 106 but also a process that should be executed before the focus changes to the stock price button 106. . In other words, not only the input of the operation of the pointing device 17 and the output of the process executed in response to the operation of the pointing device 17 but also the intermediate process that should exist between the input and the output is taken into consideration. Generated. Therefore, even when the focus is shifted from the initial state to the stock price button 106, the process of setting the profile information recorded in the permanent storage area in the memory 20 of the data broadcast receiving apparatus 1 to the variable userdata is performed.

  As described above, according to the data broadcast receiving apparatus 1 according to the present embodiment, the operation using the pointing device 17 is provided for the data broadcast content designed on the assumption that the operation using the remote controller is performed. Can do. In particular, even for data broadcasting contents described using a script such as ECMAScript, all possible operations are executed in a pseudo or virtual manner, and the execution results are collected as a processing database. An operation using the device 17 can be suitably provided.

  In the above-described embodiment, a drawing object whose focus is changed is detected as an operable drawing object. However, even a drawing object whose focus does not change may be detected as an operable drawing object as long as it is a selectable drawing object. For example, a drawing object that is uniquely associated with a predetermined key provided in the remote controller may be detected as an operable drawing object. As such an operable drawing object (for example, “blue button”, “red button”, “yellow button”, “green button”, etc. used in terrestrial digital broadcasting and BS digital broadcasting are given as an example. Even in this case, the above-described various effects can be achieved by generating a processing database that includes a record that associates a selectable drawing object that does not change focus and a process when the selected object is selected. Can enjoy.

  Further, in the above-described embodiment, it can be said that an operation using a pointing device is made possible by converting an operation with an operation key provided in the remote control into an operation at a predetermined coordinate position on the display screen of the display 14. If interpreted in this way, conversely, the content designed on the assumption of the operation using the pointing device 17 by converting the operation at the coordinate position specified by the pointing device 17 into the operation by the operation key provided in the remote controller. On the other hand, it is possible to realize the operation using the operation keys provided in the remote controller based on the same principle. An example of content designed on the premise of an operation using the pointing device 17 is a WEB page described in HTML. Even in this case, as described above, the processing database is generated (more preferably, the processing database including a record that considers not only input and output but also intermediate processes thereof). The effect similar to the effect can be enjoyed.

  The present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit or concept of the invention that can be read from the claims and the entire specification. A method and a computer program are also included in the technical scope of the present invention.
