This enables even a document-creating person without high-level knowledge to change layout information of data broadcast screen.

Description

  The present invention relates to a BCML set composed of a group of files related to BCML (Broadcast Contents Markup Language) and a parameter file generation apparatus that generates a parameter file that is one of the file groups.

  Conventionally, in a data broadcasting system, layout information is generally stored in advance in a data broadcasting management device of a broadcasting station, and article information that changes every moment is combined with this layout information and transmitted to broadcasting equipment. It is difficult to appropriately change the layout information unless advanced knowledge such as BCML, BML (Broadcast Markup Language), and ARIB (Association of Radio Industries and Businesses) standards is provided.

  For example, in the technique described in Japanese Patent Laid-Open No. 2002-262223 (Patent Document 1), advertising information is linked on the screen of the authoring root to the one selected from layout information prepared in advance as a template. It is. By using this technique, even those who are not familiar with BCML, BML, ARIB standards, etc. can link layout information and advertisement information (still images, text, etc.). However, it should be noted here that layout information is selected from those prepared in advance, and advanced knowledge such as BCML, BML, and ARIB standards is still necessary for changing layout information. is required.

JP 2002-262223 A

  Incidentally, in recent years, there has been an increasing need to be able to change layout information even by those who do not have advanced knowledge such as BCML, BML, and ARIB standards. As a specific example, there is a growing need to easily change layout information of data broadcasting in a local CATV station.

  The present invention has been considered in view of such a problem, and an object of the present invention is to provide a technique that allows a person who does not have advanced knowledge such as BCML, BML, and ARIB standards to change layout information. And

  The BCML set of the first invention made to solve the above problems is executed in a BML file in which information for configuring a data broadcast screen is described, a parameter file, and a computer built in the television receiver. The script includes a script described in the BML file or in another file, and a BCML file having information for managing the files. Among these, at least a part of the layout of the data broadcasting screen of the BML file is undetermined (the whole may be undetermined). Further, the parameter file is information in which a layout that is undetermined in the BML file is described in a binary table file format. The script forms a data broadcast screen in which a layout that has not been determined in the BML file is set based on the parameter file and the BML file. The “layout” here means at least one of the number, position, size, color, etc. of objects (buttons, content display areas) constituting the data broadcast screen.

  According to such a BCML set, a layout that is undetermined in the BML file can be changed by editing the parameter file. That is, as long as the layout editor knows the meaning of the information described in the parameter file, the layout of the data broadcast screen can be changed without knowing advanced knowledge such as BCML, BML, and ARIB standards. it can. If layout setting information is gathered in a parameter file, the layout can be easily managed. The layout of the data broadcast screen can also be changed by sending a new parameter file from the broadcast station to the television receiver after the BCML set of the present invention is sent from the broadcast station to the television receiver. Therefore, by sending a parameter file that normally has a smaller file size than the BML file, the layout of the data broadcast screen can be changed, which is useful for reducing the amount of communication data.

  The BCML set of the second invention is characterized in that the parameter file is generated by an operation by a layout editor based on a screen displayed on an Internet browser. Specifically, for example, the parameter file may be generated by a CMS (Content Management System).

If the parameter file is generated in this way, the layout editor can more easily change the layout of the data broadcast screen.
The BCML set of the third invention further includes a content file including content data used for a data broadcast screen, and the script further reads the content file to form a data broadcast screen including the content. It is characterized by doing.

  With this configuration, the layout of the data broadcast screen can be changed while associating the layout of the data broadcast screen with the content, so that a more flexible layout change can be performed.

  According to a fourth aspect of the present invention, the behavior of at least a part of objects constituting the data broadcast screen is undecided in the BML file, and the behavior of an object that is undetermined in the BML file is included in the parameter file. Is also described in a binary table file format, and the script is based on the parameter file and the BML file, and a data broadcast screen in which the behavior of an object that has not been determined in the BML file is set It is a BCML set characterized by comprising. The “behavior” here means at least one of an operation when the content or button is focused, an operation when a determination operation is performed, and the like. Further, in the BML file, the behavior of all the objects constituting the data broadcast screen may be undetermined.

  With such a BCML set, it is possible to change the behavior of an object that has not been determined in the BML file by editing the parameter file. In other words, as long as the behavior editor knows the meaning of the information described in the parameter file, the behavior of the object on the data broadcasting screen is changed without knowing advanced knowledge such as BCML, BML, and ARIB standards. be able to. In addition, if behavior setting information is collected in a parameter file, behavior management is easy. The behavior of the data broadcast screen can also be changed by sending a new parameter file from the broadcast station to the television receiver after the BCML set of the present invention is sent from the broadcast station to the television receiver. Therefore, the behavior of the data broadcast screen can be changed by sending a parameter file that normally has a smaller file size than the BML file, which is useful for reducing the amount of communication data.

  According to a fifth aspect of the present invention, there is provided a parameter generation device including a presentation unit, a reception unit, and a parameter file generation unit. The presenting means is means for prompting the operator to input information regarding the undecided element (information defined by the start tag and end tag) in the BML file file in which at least a part of the layout of the data broadcast screen is undecided. is there. The “layout” here means at least one of the number, position, size, color, etc. of objects (buttons, content display areas) constituting the data broadcast screen. The accepting means is means for accepting the input of the information prompted by the operator by the presenting means from the operator. Further, the parameter file generation means is a parameter in a binary table file format used for constructing a data broadcast screen in which a layout that has not been determined in the BML file is set by a script executed in a computer built in the television receiver. It is means for generating a file based on the information received by the receiving means.

  According to such a parameter file generation device, the layout editor inputs information related to the layout urged by the presenting means to the accepting means, whereby a data broadcast screen in which a layout that has not been determined in the BML file is configured. A parameter file is generated for use in the process. For this reason, if the method of prompting the input prompted by the presentation means is appropriate, the layout editor can change the layout of the data broadcast screen without knowing advanced knowledge such as BCML, BML, and ARIB standards. it can.

  In the parameter generation device of the sixth invention, the BML file is also undetermined for the behavior of at least some of the objects constituting the data broadcast screen, and the presenting means is also capable of inputting information regarding the behavior. Prompting the operator, the accepting means also accepts input of the information prompted by the operator by the presenting means from the operator, and the parameter file generating means is a parameter file used by the script to set the behavior Is generated based on the information received by the receiving means. The “behavior” means at least one of an operation when the content or button is focused, an operation when a determination operation is performed, and the like.

  According to such a parameter file generation device, the behavior editor inputs information relating to the undetermined behavior prompted by the presentation unit to the receiving unit, whereby the data broadcast screen in which the undetermined behavior is set in the BML file A parameter file to be used when is configured is generated. For this reason, if the method of prompting the input prompted by the presenting means is appropriate, the behavior editor can change the behavior of the data broadcast screen without knowing advanced knowledge such as BCML, BML, and ARIB standards. it can.

  The parameter file generating device of the seventh invention is characterized in that the parameter file generating means further generates an XML format file including contents equivalent to the parameter file.

  In this way, if an XML format file containing the same content as the parameter file is generated, if a script such as JAVAScript having the same function as the script described above is prepared separately, the editor is expensive. Even without preparing a data broadcasting browser, it is possible to perform a test browsing of the data broadcasting screen using a general-purpose Internet browser, and the parameter file can be easily edited appropriately.

[3. Description of the workflow of the manuscript creator]
Next, the work flow of the manuscript creator most closely related to the present invention will be described based on the flowchart of FIG.

  The manuscript creator operates the manuscript creator terminals 13a, 13b, and 13c to log in the data broadcast screen production system 11 (S105). This login process is mainly realized by the user management function 27. When logging in to the data broadcasting screen production system 11 with the authority as a manuscript creator, a menu screen in which buttons associated with the screen template editing screen, the content input screen, and the approval request screen are arranged is generated as a screen. It is displayed on the monitor by the function 21 and the work corresponding to each screen can be executed.

  Next, the document creator presses a button associated with the screen template editing screen on the screen to display the screen template editing screen (S110). In the screen template, layout information about the screen, behavior information of objects constituting the screen, and the like are defined. Specifically, the position, size, and color of objects and buttons for arranging content, the behavior when the buttons are operated, and the behavior when the color buttons of the remote control are operated are defined. This screen template corresponds to the rest of the BCML set 51 described later, excluding the monomedia file 55, the content file 67, and the BCML file 69 (see FIG. 4). The screen template editing screen will be described later. Note that this step can be skipped if screen templates created in the past are used as they are.

  Next, the document creator depresses a button corresponding to the content input screen on the menu screen to display the content input screen (S115). In this content input screen, the document creator first selects a screen template for inputting content. Here, what was previously created on the screen template editing screen is selected. Then, the manuscript creator inputs the content to be applied to the selected screen template, that is, the text information including the title and body of the article information, and various mono-media (image, simple video, and audio) files. Specify a name. If the monomedia has already been uploaded to the CMS server 17, the monomedia can be incorporated into the data broadcast screen simply by specifying the file name, but the monomedia file has not yet been registered in the CMS server 17. In this step, the mono media file can be uploaded to the CMS server 17.

  Subsequently, the document creator previews the data broadcast screen (S120). This is mainly realized by the preview function 25. As a result of the preview, if the data broadcast screen is not as intended by the manuscript creator, the above steps S110 and S115 are performed again.

  As a result of the preview, when it is confirmed that the data broadcast screen is as intended by the manuscript creator, the manuscript creator makes an approval request to an approver who has authority to transmit the data broadcast screen (S125). ). Thereafter, when the approver approves the transmission of the data broadcast screen, the approval result is written in the DB 31, and the approved data broadcast screen has a BCML set as a file group related to the data broadcast screen from the CMS server 17. Transmission to the broadcast transmission device 19 becomes possible.

[4. Explanation of BCML set]
Next, an example of the BCML set will be described with reference to the block diagram of FIG. The BCML set is composed of various files transmitted from the CMS server 17 to the data broadcast transmission device 19, and is a group of files that can configure a data broadcast screen. This BCML set is sent from the data broadcast sending device 19 to the broadcasting equipment in accordance with the broadcasting timing, and finally delivered to the television receiver.

  The BCML set 51 shown in FIG. 4 includes a BML file 53, a mono media file 55, an ECMAScript file 57, a layout BTB 59, a template BTB 61, a color group BTB 63, a color master BTB 65, a content file 67, and a BCML file. 69.

The BML file 53 is a file in which basic information for configuring a data broadcasting screen is described. The file name of the CSS file 54 to be used, the ECMAScript file 57 to be used, the monomedia file 55 to be used fixedly, and the like. CSS file 54 is a file in which Cascading Style Sheets are described, and specifies in advance how to modify (display) elements in BML (information defined by start and end tags). It is a file that contains information to keep.

The mono media file 55 is a file of various mono media such as an image file, a simple moving image file, and an audio file.
The ECMAScript file 57 is a file in which a script based on ECMAScript is described, and the script described in this file is executed by a control unit (part consisting of CPU, memory, various interfaces, etc.) built in the television receiver. . This script refers to the layout BTB 59, template BTB 61, color group BTB 63, color master BTB 65, mono-media file 55, and content file 67, and executes processing for outputting a data broadcast screen.

The layout BTB 59 is a binary table format file in which information on the display position, display style, and behavior of each object constituting the data broadcasting screen is defined.
The template BTB 61 is a binary table format file in which a template for reducing the labor for setting the layout BTB 59 is externally defined. More specifically, information on a finer GUI operation is defined for each category of objects constituting the data broadcast screen (eg, button type).

  In the color master BTB 65, a combination of display color values (for example, color-index, grayscale-color-index, background-color-index in CSS) (hereinafter referred to as “color set”) is defined by a color set name. It is a binary table format file. Information mainly used for character color expression is defined.

  The color group BTB63 is a binary table format file in which the color sets defined in the color master BTB65 are grouped and defined as a color group (color group).

The content file 67 is a file in which text to be displayed as article information in the data broadcast screen is described. This file is also a binary table format file.
The BCML file 69 is a definition file used by a data broadcast transmission device such as the data broadcast transmission device 19 to manage data broadcast contents, that is, a BCML set.

[5. Layout BTB editing screen]
Next, a screen example when editing the layout BTB 59, which is one of the setting files constituting the screen template, will be described with reference to FIG. Here, the layout BTB 59 is taken up, but the template BTB 61, the color group BTB 63, and the color master BTB 65 are the same in the editing method except for the setting items.

  As shown in FIG. 5, the editing screen 101 of the layout BTB 59 mainly includes a line designation area 103, a parameter setting area 105, a registration button 107, and a preview 109.

  A row designation area 103 indicates each row of the layout BTB 59. Note that the term “row” here refers to one row corresponding to one object, and is a logical unit. By clicking a numerical link designated in the row designation area 103 on the screen, the setting information of the object corresponding to the clicked line is displayed in the parameter setting area 105.

  The parameter setting area 105 includes an object number field 105a, a template name field 105b, a function name field 105c, a function parameter field 105d, an access key field 105e, a focus destination (up) field 105f, a focus destination (down) field 105g, and a focus destination ( left) column 105h, focus destination (right) column 105i, proxy focus destination (up) column 105j, proxy focus destination (down) column 105k, proxy focus destination (left) column 105m, proxy focus destination (right) column 105n, display The area parameter column 105o, the state interlocking image parameter column 105p, the state interlocking text parameter column 105q, and the additional parameter column 105r are configured.

  The object number column 105a is a column for setting an object number, and a unique number automatically assigned is set in the initial state. The subsequent columns (template name column 105b to additional parameter column 105r) are information relating to an object (hereinafter referred to as “edit target object”) specified by the object number. In the example of FIG. 5, “81” is set as the object number.

  The template name column 105b is a column for setting a template name used by the object to be edited. The template name specified here is a template name set in the template BTB 61, which is a template for reducing the labor for setting the object to be edited, and is a name of a template that can be used for other objects. In the example of FIG. 5, “colorBtn” indicating the template name related to the color buttons of the remote controller is set as the template name.

  The function name column 105c is a column for setting a function name on the data broadcast screen. “Function” in the data broadcasting screen is an individual processing unit that realizes the data broadcasting screen. For example, processing when a button is pressed, processing for displaying an article in the data broadcasting screen, An example of processing when a color button on the remote control is pressed is given. These functions have processing modules in ECMAScript that realize the functions. In the example of FIG. 5, “colorBtn”, which is a function when the color button of the remote controller is pressed, is set as the function name. When a special function name “layout” is set as the function name, a special process described later is executed.

  The function parameter column 105d is a column for setting a parameter (function parameter) for the function specified in the function name column 105c. In the example of FIG. 5, “1” indicating the blue button is set as the function parameter.

  The access key column 105e is a column for setting a remote control button that is handled as if the object to be edited is pressed. In the example of FIG. 5, “B” indicating a blue button is set.

  The focus destination (up) column 105f is a column for designating an object number as a movement destination when the upper button of the remote control is pressed when the focus is on the object to be edited. In the example of FIG. 5, the focus is set to move to the object whose object number is “12”.

  The focus destination (down) column 105g is a column for designating an object number as a movement destination when the lower button on the remote control is pressed when the focus is on the object to be edited. In the example of FIG. 5, the focus is set to move to the object whose object number is “240”.

  The focus destination (left) column 105h is a column for designating an object number as a movement destination when the left button of the remote control is pressed when the focus is on the object to be edited. In the example of FIG. 5, the focus is set to move to the object whose object number is “99”.

  The focus destination (right) column 105i is a column for designating an object number as a movement destination when the right button of the remote controller is pressed when the focus is on the object to be edited. In the example of FIG. 5, the focus is set to move to the object whose object number is “82”.

  In the proxy focus destination (up) column 105j, the focus destination when the upper button of the remote controller is pressed in the setting of another object is set to the object (edit target object) currently being edited. Regardless, if the focus cannot be assigned (for example, it is inappropriate to hold the button because the button cannot be pressed), the focus is forcibly moved to another object ( This is a field for designating an object number as a movement destination for proxy focus. A specific example of this proxy focus will be described later. In the example of FIG. 5, “0” indicating that the focus does not move is set.

  The proxy focus destination (down) column 105k is the same as the proxy focus destination (up) column 105j, and the difference is that the proxy focus destination object number in the case of the remote control down button instead of the remote control up button is designated. That is.

  The proxy focus destination (left) column 105m is the same as the proxy focus destination (up) column 105j, except that the proxy focus destination object number when the left button of the remote control is used instead of the upper button of the remote control is designated. That is.

  The proxy focus destination (right) column 105n is the same as the proxy focus destination (up) column 105j, except that the proxy focus destination object number when the right button of the remote control is used instead of the upper button of the remote control is specified. That is.

  The display area parameter column 105o is a column for setting the reference point (the upper left coordinates of the object) of the area where the target object is displayed. In the example of FIG. 5, “left: 180; top: 460” is set, and when the origin of the data broadcasting screen is placed at the upper left of the screen (in the absolute coordinate system), the upper left position of the object is It is set to be (180, 460).

  The state-linked image parameter column 105p is a column for setting information about an image displayed when the target object is in focus or when the target object is determined. Specifically, for example, an image display position, an image file name, and the like are set. In the example of FIG. 5, it is not set.

  The state interlocking text parameter column 105q is a column for setting information regarding text to be displayed superimposed on the target object. For example, the display position of the text and the display mode of the text to be displayed are set. In the example of FIG. 5, it is not set.

  The additional parameter column 105r is a column for setting function parameters similar to the function parameter column 105d, and is a column used for further setting separately from the function parameter column 105d. In the example of FIG. 5, “[png] :: data: new.png; top: 3; left: 80; width: 36; height: 20” is set, in other words, “[png ] ”Is specified,“ new.png ”is specified as the PNG file to be referenced, and the upper left position of the PNG file is relative to the upper left position of the display area set in the display area parameter field 105o. The coordinate position is set to (3, 80) (that is, the absolute coordinate position is (183, 540)), the width of the PNG file is set to 36 pixels, and the height of the PNG file is It is set as 20 pixels. The extended object selector will be described later.

[6. Explanation on proxy focus]
Next, proxy focus will be described with reference to the flowcharts of FIGS. 6 and 7 and the explanatory diagrams of FIGS.

(1) Direction Button Pressing Process First, the direction button pressing process executed by the control unit of the television receiver based on the script described in the ECMAScript file 57 will be described using the flowchart of FIG.

  When one of the direction buttons on the remote controller is pressed by the user of the television receiver, the control unit of the television receiver starts executing the direction button pressing process. When starting the execution of the direction button pressing process, the control unit first executes a destination focus item search process (S205). This process is a process of searching for and specifying an object to be assigned the next focus on the basis of the object having the current focus. Details will be described later.

  Subsequently, in the destination focus item search process, the control unit branches the process depending on whether or not the search for the object to which the focus is assigned next is successful (S210). If the search for the object to which the focus is assigned next is successful (S210: Yes), the process proceeds to S215, and if the search for the object to which the focus is assigned next is not successful (S210: No). ) This process (direction button pressing process) is terminated without moving the focus from the object to which the focus is currently assigned.

  In S215, when the search of the object to which the focus is assigned next is successful, the focus is moved from the object to which the focus is currently assigned to the object identified by the destination focus item search process. This process (direction button pressing process) is terminated.

(2) Destination Focus Item Search Process Next, a destination focus item search process called in the direction button pressing process will be described using the flowchart of FIG. The destination focus item search process is also executed by the control unit of the television receiver.

  When the destination focus item search process is called, the control unit of the television receiver searches for the object number of the focus destination corresponding to the type of the direction button of the remote control that triggered the execution of the direction button pressing process (S255). For example, when the upward direction button is pressed, the record information of the layout BTB 59 having the object number of the object to which the focus is currently assigned is referred to, and the remote control up button included in the information is pressed. The object number of the focus movement destination (number input in the focus destination (up) field 105f in FIG. 5) is acquired.

  Subsequently, the control unit branches the process according to the search result of S255 (the search result of S290 when the process has shifted from S290 to S260) (S260). Specifically, the process branches depending on whether or not the object number found by the search is “0”. If the object number found by the search is “0” (S260: Yes), the process proceeds to S265, and if the object number found by the search is not “0” (S260: No). , The process proceeds to S270.

  In S265 to which the process proceeds when the object number found in the search is “0”, the control unit recognizes that the search for the object to which the focus is assigned next has failed, and performs this process (destination focus item search process). When finished, the process proceeds to the next step of the caller's direction button pressing process.

  On the other hand, when the object number found in the search is not “0”, in S270, the focus is set on the object found in the search in S255 (if the process moves from S290 to S260: NO and the process moves to S270). It is determined whether or not it can be assigned, and the process branches depending on the determination result. Whether or not the focus can be assigned is an agreement as to whether or not the television receiver user can perform an operation such as determination on the object. For example, the content or object corresponding to the object can be determined. If a media file exists and if the determination operation is performed on the object, the corresponding object can be displayed, it is determined that the focus can be assigned to the object. On the other hand, if there is no content or monomedia file corresponding to the object and the corresponding object cannot be displayed even if the decision operation is performed on the object, it is impossible to assign focus to the object. Judge that it is possible.

  If it is determined that the focus can be assigned to the object found in the search of S255 (or the search of S290) (S270: Yes), the process proceeds to S275 and the search of S255 (or the search of S290) is performed. If it is determined that the focus cannot be assigned to the object found in (S270: No), the process proceeds to S280.

  In step S275, which is performed when it is determined that the focus can be assigned to the object found by the search, the control unit recognizes that the search of the object to which the focus is assigned next is successful, and performs this processing (destination focus item search). The process is terminated, and the process proceeds to the next step of the caller's direction button pressing process.

  On the other hand, if it is determined in step S280 that the focus cannot be assigned to the object found by the search, the control unit cannot start assigning the focus after starting this processing (destination focus item search processing). It is determined whether or not the determined number has reached a predetermined value, and the process branches depending on the determination result. The default value here may be, for example, the upper limit being the number of records of the layout BTB 59 (= the number of focus items). When it is determined that the number of times it has been determined that the focus cannot be assigned has reached a predetermined value (S280: Yes), the process proceeds to S285, and the number of times it has been determined that the focus cannot be assigned has reached the default value. If not (S280: No), the process proceeds to S290.

  In S285, which proceeds when it is determined that the number of times it has been determined that the focus cannot be assigned has reached a predetermined value, the control unit recognizes that the search for the object to which the focus is assigned next has failed, and performs this processing (destination focus). The item search process is terminated, and the process proceeds to the next step of the caller direction button pressing process.

  On the other hand, if it is determined that the number of times it has been determined that the focus cannot be assigned has not reached the predetermined value, the process proceeds to S290 where the object number of the proxy focus destination of the object that has been determined that the focus cannot be assigned is searched. For example, when the upward direction button of the remote control is pressed, the record information of the layout BTB 59 having the object number of the object determined to be unable to be assigned the focus is referred to, and the remote control upper button included in the information is pressed The object number of the substitute focus movement destination at that time (the number input in the substitute focus destination (up) column 105j in FIG. 5) is acquired. When the control unit performs the search, the process proceeds to S260.

(3) Specific Example Next, a specific example of focus movement will be shown. FIG. 8A is an example of a data broadcast screen, in which four buttons are arranged for explanation. In this data broadcasting screen, a left button 201 is arranged on the left side of the upper stage, a center button 202 is arranged in the center of the upper stage, a right button 203 is arranged on the right side of the upper stage, and a lower button 204 is arranged on the lower stage. The left button 201 is assigned “1” as the object number, the center button 202 is assigned “2” as the object number, and the right button 201 is assigned “3” as the object number. The lower button 204 is assigned “4” as the object number. In the following, description will be made on the premise of this data broadcasting screen.

  FIG. 8B is a table in which setting information of the focus destination and proxy focus destination of the object numbers “1” to “4” among the information included in the layout BTB 59 is summarized. FIG. 8C schematically illustrates the focus movement based on the setting information. For example, it is expressed that when the right button of the remote control is pressed while the left button 201 is in focus, the focus moves to the button having the object number “2”, that is, the center button 202 (arrow). 201a), when the upper button of the remote controller is pressed, the focus moves to the button with the object number “4”, that is, the lower button 204 (see arrow 201b). In addition, when the upper button of the remote control is pressed and the left button 201 is selected as a focus destination, it is not appropriate to move the focus to the button (for example, an operation corresponding to the button cannot be executed). In the case of a situation), it is expressed that the focus moves to the button of the object number “3”, that is, the right button 203 instead (see the arrow 201c).

  This will be further described with reference to FIG. Assume that the lower button 204 is currently focused. In this situation, when the right button or the left button of the remote control is pressed, the focus is not moved because the lower button 204 is set to move the focus to the button with the object number “0”. Absent. In addition, when the upper button of the remote control is pressed on the assumption that the lower button 204 has the focus, the lower button 204 is set to move the focus to the button having the object number “1”. The button with the number “1”, that is, the left button 201 is not displayed on the screen and cannot be assigned focus. Therefore, when the upper button of the remote control is pressed for the object with the object number “1” The focus moves to the button of the object number “3” set as the focus destination, that is, the right button 203. In addition, when the lower button of the remote control is pressed on the assumption that the lower button 204 has the focus, the lower button 204 is set to move the focus to the button having the object number “1”. The button with the number “1”, that is, the left button 201 is not displayed on the screen and cannot be assigned the focus. Therefore, when the lower button of the remote control is pressed on the object with the object number “1”, the proxy focus destination The focus moves to the button of the object number “2” set as, that is, the center button 202.

  In this way, when an instruction to move the focus is received from the remote control, basically, the focus is set to the focus destination set for the currently focused button and the destination is focused. Moves, but when the move destination cannot be assigned focus, the focus is not assigned to the move destination, and it is a proxy focus destination that is set as the move destination and moves corresponding to the move instruction direction Operates to move focus first. Therefore, when the document creator sets an object that is an editing screen as shown in FIG. 5, for example, the focus destination can be set without considering whether the focus destination can be assigned a focus. The object can be set easily.

[7. Example of data broadcasting screen]
Next, an example of the data broadcast screen will be described with reference to FIG.
A data broadcast screen 111 shown in FIG. 10A is a screen displayed when the data broadcast display button of the remote control is pressed in the program viewing state.

  There is a program display column 112 at the upper left of the data broadcast screen 111, and a program broadcast on the selected channel is reduced and displayed. Further, on the right side of the program display column 112, there is a transition button 113 on another screen, and when pressed, the screen transitions to a data broadcast screen composed of another BML set. In addition, a previous item button 114 is provided below the program display column 112. When the button is pressed, a previous set of article titles displayed on article title buttons 115a to 115e (to be described later) (multiple sets of article titles are prepared in units of five). The previous set) is a button for displaying. Further, below the previous item button 114, there are article title buttons 115a to 115e for displaying the titles of articles related to the program broadcast on the selected channel. Each of the article title buttons 115a to 115e can be pressed. When the button is pressed, the article title buttons 115a to 115e are also buttons for displaying the details of the article in an article content column 122 described later.

  Below the article title buttons 115a to 115e is a next item button 116, which is a button for displaying the next set of article titles displayed on the article title buttons 115a to 115e when pressed.

  Below the next item button 116 is a return button 117. When this button is pressed, the display of the data broadcast screen is completed and the program broadcast on the selected channel is displayed on the entire screen. .

  On the right side of the return button 117, there are a blue button 118, a red button 119, a green button 120, and a yellow button 121, each of which indicates that some processing corresponding to the color button of the remote control is performed.

  On the right side of the article title buttons 115a to 115e, there is an article content column 122, which is an area for displaying a detailed article corresponding to one article title button selected from the article title buttons 115a to 115e. When one article title button is selected from the article title buttons 115a to 115e by the OK button on the remote control and then the right button on the remote control is further pressed, the next page (second page) of the detailed article is displayed. It has become so. When the left button of the remote control is pressed while the next item is displayed, the previous page (first page) of the detailed article is displayed. In addition, when an article title button is selected from among the article title buttons 115a to 115e by the remote control enter button and then the remote control enter button is further pressed, the related image of the detailed article is displayed. ing.

  The data broadcast screen 131 shown in FIG. 10B is the data broadcast screen 11 shown in FIG. 10A after one article title button is selected from the article title buttons 115a to 115e by the decision button on the remote control. Furthermore, it is an example of a screen (screen on which a related image of a detailed article is displayed) that is displayed when a determination button on the remote control is pressed.

  The related image of the detailed article is displayed in the superimposed article content column 133 so as to be superimposed on the article content column 132 of the data broadcast screen 131. The superimposed article content column 133 includes a close button 134, which is a button for returning to the display state of the data broadcast screen 131 shown in FIG. 10A when this button is pressed.

According to the data broadcast screen described above, the focus items (objects that can be operated by the user) include the following.
-Transition button 113 on another screen
・ Previous item button 114
Article title buttons 115a-115e
Next button 116
・ Back button 117
・ Blue button 118
・ Red button 119
・ Green button 120
・ Yellow button 121
Close button 134
Therefore, it can be seen that at least 14 records (rows) related to buttons in the layout BTB are required.

[8. Introduction of functions]
Next, examples of “functions” that need to be set on the editing screen of the layout BTB 59 will be introduced. As described above, the “function” assigned to an object is an individual processing unit that realizes a data broadcast screen. For example, processing when a button is pressed or displaying an article in the data broadcast screen For example, and processing when a color button on the remote control is pressed. Note that the processing modules (codes) for realizing these functions exist in the ECMAScript file 57.

  In the example illustrated in FIG. 11, the button function is assigned to the transition button 141 on another screen, and the button function realizes processing when a general-purpose button is pressed by a remote control operation.

  The content function is assigned to the article title buttons 143a to 143e, the previous item button 143f, and the next item button 143g. The content function is a process for displaying a corresponding detailed article in the article content field 145 when the article title button is pressed by a remote control operation, control of the article content field 145 (the right button on the remote control is pressed after the detailed article is displayed) And the article title button control when the previous button 143f or the next item button 143g is pressed (such as a process for changing the title).

  A back function is assigned to the return button 147, and the back function realizes processing when the return button is pressed by a remote control operation (for example, processing for ending the data broadcast screen).

  A colorBtn function is assigned to the blue button 148, the red button 149, the green button 150, and the yellow button 151. The colorBtn function is a process that is performed when the color button of the remote control is pressed, for each color button color. The processing corresponding to is realized.

These functions are designated on the screen for editing the layout BTB 59 (FIG. 5).
[9. Explanation of parameter application]
Next, processing in which the BCML set 51 is received by the television receiver and a data broadcast screen is constructed and displayed based on parameters such as the layout BTB 59 included in the BCML set 51 will be described.

(1) BML file read processing When a user of a television receiver gives an instruction to display a data broadcast screen to a remote control or the like, the BML browser stored in the television receiver executes (in other words, the BML browser is The BML file reading process (executed by the executing control unit) will be described with reference to the flowchart of FIG.

  When the control unit of the television receiver starts executing the reading process of the BML file, first, it reads a predetermined BML file 53 (S305). The predetermined BML file 53 here is, for example, the BML file 53 included in the BCML set 51 corresponding to the channel being broadcast. In addition, reading means expanding from a data broadcast reception buffer in the television receiver to a memory that can be directly accessed by the CPU in the control unit.

  Subsequently, the control unit constructs a DOM (Document Object Model) based on the BML file 53 read in S305 (S310). This is a process for enabling the elements included in the BML file 53 to be operated from the script of the ECMAScript file 57 via the DOM.

Subsequently, the control unit reads the CSS file 54 and the ECMAScript file 57 (S315).
Subsequently, the control unit applies the style set in the CSS file 54 read in S315 to the elements of the BML file 53 (S320).

  Subsequently, the control unit reads an image file that is externally referenced in the element in the BML file 53 (S325). The image file is only read and not displayed (output to the screen).

  Subsequently, the control unit combines the ECMAScript in the BML file 53 and the external ECMAScript file 57 (S330). However, combining is not performed unless ECMAScript is described in the BML file 53.

  Subsequently, the control unit displays the processing result on the screen of the television receiver (S335). However, in this display state, nothing is displayed yet, such as buttons and contents, and this is a temporary display state.

  Subsequently, the control unit generates an Onload interrupt event (S340). Thereby, the execution of the Onload event process based on the script described in the ECMAScript file 57 is started, and buttons, contents, and the like are displayed.

(2) Onload Event Processing Next, Onload event processing based on the script described in the ECMAScript file 57 will be described with reference to the flowchart of FIG.

When starting the execution of the Onload event process, the control unit of the television receiver first initializes a library used in the script described in the ECMAScript file 57 (S355).
Subsequently, the control unit of the television receiver specifies the function name of the function used in the BML file 53 (S360). Here, “function” means a function as described in “8. Introduction of Function”, and the function name is specified in order to execute a process (S370) described later for each function name. It is.

  Subsequently, the control unit takes out the function names specified in S360 one by one, specifies the function names, and repeatedly executes the parameter application process (S370) for the number of function names specified in S360 (S365). This parameter application processing is to apply parameters such as display position, display size, display mode, and operation to each object constituting the data broadcast screen, and will be described in detail later.

  Subsequently, the control unit reads external data (for example, the content file 67 and the monomedia file 55) necessary for each function, and completes the data broadcast screen (S375). Then, the control unit sets the focus on the object as a predetermined default focus item (S380), and ends this process (Onload event process).

By this Onload event process, the completed data broadcast screen is displayed, and the operation from the user of the television receiver is accepted.
(3) Parameter Application Processing Next, parameter application processing based on the script described in the ECMAScript file 57 will be described using the flowchart of FIG. This parameter application process is a process called in the above-described Onload event process.

  When starting the execution of the parameter application process, the control unit of the television receiver first searches the layout BTB 59 for all the records in which the function name that matches the function name specified when this process is called ( S405).

  Subsequently, the control unit of the television receiver selects one record searched in S405, and repeatedly executes the following processes of S415 to S450 for the number of searched records while changing the record to be selected (S415). ).

  In S415, it is determined whether or not the function name of the record selected in S410 is “layout”. The record whose function name is “layout” is a special record that is different from others, and is intended to apply parameters to specific elements using information set in the function parameter items. is there. Note that the function name of the special record is “layout” as an example, and the present invention is not limited to this.

  When it is determined that the function name of the record selected in S410 is “layout” (S415: Yes), the control unit proceeds to S420, and the function name of the record selected in S410 is not “layout”. If it is determined (S415: No), the process proceeds to S430.

  In S420, which proceeds when it is determined that the function name of the record selected in S410 is “layout”, information set as a function parameter in the record (eg, “logo :: data: logo.png; top: 30 ; left: 700; width: 204; heigt: 43; visibility: 1 ”), a selector (eg,“ logo ”) is taken out, and a DOM object is acquired based on the selector. Details of this acquisition will be described later as element allocation processing.

  Subsequently, the control unit sets a parameter (for example, “data: logo.png; top: 30; left: 700; width: 204; heigt: 43; visivility: 1”) for the DOM object acquired in S420. (S425). Specifically, image file designation, arrangement position designation, size designation, display presence / absence designation, and the like.

  On the other hand, if it is determined that the function name of the record selected in S410 is not “layout”, in S430, the template BTB 61 is searched for a template record corresponding to the template name of the record selected in S410, and the parameters are combined. To complete.

  Then, the control unit takes out the selector in the parameter completed in S430, and acquires the DOM object based on the selector (S435). Details of this acquisition will be described later as element allocation processing.

  Subsequently, the control unit sets a parameter for the DOM object acquired in S435 (S435). Specifically, image file designation, arrangement position designation, size designation, display presence / absence designation, and the like. At this time, the color master BTB 65 and the color group BTB 63 are also applied to the DOM object.

  Subsequently, the control unit creates a focus item object corresponding to the DOM object acquired in S435, and associates it with the DOM object (S455). The focus item object is an object for bridging between the function and the DOM object, and aims to hide the DOM object from the function and facilitate the operation of the DOM object from the function.

  Subsequently, the control unit associates the focus item object generated in S445 with the function designated when this processing is read (S450). As a result, the DOM object can be operated from the function via the focus item object.

  The control unit repeatedly executes the processes in S415 to S450 as many times as the number of records searched in S405. When the execution of these processes is completed for all the retrieved records, the process proceeds to the next step of the Onload event process that is the caller of this process.

[10. Explanation of element assignment processing]
The element assignment process performed by the script described in the ECMAScript file 57 will be described. By this element assignment process, the DOM object of the specified element is acquired and the element can be operated in the script. In this process, the following measures are taken.

  ECMAScript that runs on current television receivers has an attribute of an element whose value cannot be specified (operated) directly from the script. The “value” is a value that includes not only numbers but also characters. The device is prepared in the BML file 53 as an element for each value of the attribute, and by selecting a specific element from the script, it is possible to realize that an attribute that cannot be specified in the specification can be specified by a desired value as a result. Is going. Hereinafter, the element allocation process will be described with reference to FIG.

  As shown in FIG. 15, the script described in the ECMAScript file 57 includes at least processing descriptions constituting a parameter BTB analysis / application unit 57a, an element allocation management unit 57b, and a function processing unit 57c.

  First, the parameter BTB analysis / application unit 57a refers to the parameter file (layout BTB59, template BTB61, color group BTB63, and color master BTB65), and analyzes the parameters of each object constituting the data broadcast screen. As a result, if a parameter that requires element allocation is included, an element allocation request is made to the element allocation manager 57b.

  Upon receiving the element allocation request, the element allocation management unit 57b searches the general-purpose element group 53a or other element group 53b described in the BML file 53 via the DOM interface 71, and acquires the DOM object of the corresponding element. And return it to the requester. Specific examples of the general-purpose element group 53a and the other element group 53b described in the BML file 53 will be described later. The DOM interface 71 is a Document Object Model interface and is an API (Application Program Interface) for referring to a BML file from a script. The concept of this interface is recommended by the W3C, is widely used in programming languages using XML, and can also be used in ECMAScript for data broadcasting. Via this interface, it is possible to acquire / change the attribute value and CSS characteristic value of an element in a BML file from a script, and to access an element (parent element, child element, sibling element) adjacent to the element. it can.

The element allocation management unit 57b that has obtained the DOM object of the element notifies the parameter BTB analysis / application unit 57a of the DOM object.
Upon receiving this notification, the parameter BTB analysis / application unit 57a applies the contents of the parameter to the notified DOM object, specifies the function name specified for the object, and notifies the function processing unit 57c.

The function processing unit 57c implements a function using the notified DOM object.
Here, it demonstrates using a specific example. There is “text-align” as a CSS characteristic in which a value cannot be directly designated (manipulated) from a script in the specification of ECMAScript operating on the current television receiver. This is an attribute for designating the direction in which a character string is displayed on the screen. Values include “left”, “center”, “right”, and the like. In order to designate this from the script, a description as shown in FIG. 16A is included in the CSS file 54 in advance. The description on the first line in FIG. 16A means that a class in which left is specified in the text-align attribute of the p element is defined as tmp # text. Similarly, the description on the second line means that a class in which center is specified in the text-align attribute of the p element is defined as tmp # text # center. Similarly, the description on the third line means that a class in which right is specified in the text-align attribute of the p element is defined as tmp # text # right. By defining the class in this way, it is possible to move the text to the left, center, or right on the screen simply by specifying one of the classes for the p element in the BML file 53. .

  Subsequently, the specific description of the general-purpose element group 53a of the BML file 53 is confirmed. FIG. 16B is an example of a general-purpose element of the general-purpose element group 53a in the BML file 53, and is a set of screen constituent elements for displaying center-aligned text. The first line is a start tag of the div element and is defined as having an id attribute of tmp # text # center. The second line specifies the tmp # text # center class as the p element and the tmp # text # center class as the div element for the character string specified by the CDATA section. The same applies to the third to n-1th rows. The reason why there are a plurality of lines having the same content is that when the same general-purpose element is designated for each of the plurality of objects in the layout BTB 59, the element allocation management unit 57b needs to individually respond to the request for the general-purpose element allocation. This is because it is necessary to secure the quantity that will be used on one data broadcasting screen. The nth line is an end tag of the div element. Such general-purpose elements composed of n rows are described for the case of center alignment and the case of right alignment, respectively.

  By describing the general-purpose element group 53a in this way, the parameter BTB analysis / application unit 57a and the element assignment management unit 57b cooperate with each other according to the attribute setting value in the parameter file, and the BML file 53 according to the purpose. The element (DOM object) inside can be acquired. When the DOM object is notified to the parameter BTB analysis / application unit 57a, the parameter BTB analysis / application unit 57a sets other CSS, attribute values, and the like through the DOM object. Then, the function processing unit 57c is notified of the DOM object.

  As a result, the function processing unit 57c can realize the function by using the DOM object set including the attribute value of the element whose value cannot be directly designated (operated) from the script according to the ECMAScript specification.

  Note that which general-purpose element group 53a or other element group 53b is selected is determined by the selector and attribute value described in the parameter file, but in this embodiment, the selector is roughly classified into two types. be able to. One is a case where the id attribute described in the BML file 53 is directly designated as a selector, and the other is a case where an intermediate selector (hereinafter referred to as “extended object selector”) is designated. When the extended object selector is specified, the parameter BTB analysis / application unit 57a converts the extended object selector into the id attribute.

A specific example of the extended object selector used in the data broadcast screen production system 11 of this embodiment will be given.
・ "[Div]"… Display the rectangular area → Specify the div element ・ "[jpeg]"… Display the jpeg image → Specify the object element that references the jpeg image ・ "[png]"… Display the png image → png image Specify the objcet element to display ・ "[text]"… Display text → Specify p element In addition, the following examples are given as usage.

・ [Div] :: left: 60; top: 480; width: 109; heigt: 40
・ [Png] :: width: 109; height: 160; data: btnB # 109x40.png
[Text] :: top: 10; textAlign; center; fontSize: 20; colorGroup: btn1
In the first usage method, a rectangular area having a width of 109 pixels and a height of 40 pixels is specified at a position of (60,480) pixels from the upper left of the screen. The second one designates a PNG image having a width of 109 pixels and a height of 160 designated by the file name “btnB # 109x40.png”. The third one designates text that is center-aligned, has a font size of 20, and uses a color group of “btn1” at a position of 10 pixels from the screen.

  Since such an extended object selector can be used, the manuscript creator does not need to know the id attribute described in the BML file 53, so the burden on the manuscript creator is reduced.

[11. Explanation of parameter binding]
Next, a specific example of processing for generating parameters related to objects constituting the data broadcast screen by combining the layout BTB 59 and the template BTB 61 will be described. This process is performed on the ECMAScript file 57 by the parameter BTB analysis / application unit 57a.

  In the layout BTB 59 shown in FIG. 17, “81” is described as the object number, “colorBtn” is described as the function name, “1” is described as the function parameter, “B” is described as the access key, and the focus The movement parameter group is also described although the contents are omitted. These are used as parameters for the object as they are without referring to the template BTB 61 at all.

  On the other hand, in the layout BTB 59 shown in FIG. 17, “colorBtn” is described as a template name. Based on this, the template BTB 61 is referred to, and a parameter related to “colorBtn” is selected. The selected items are the display area parameter (“width: 190; height: 80” in this example) and the state-linked image parameter (“width: 190; height: 240; data: btnColor # 190x80.png in this example) "), A state-linked text parameter (in this example," top: 20; textAlign: center; fontSize: 20; colorGroup: btn1 "), and an additional parameter (in this example, no setting). The selected parameters are the display area parameter in the layout BTB 59 (in this example, “left: 180; top: 460”), the state-linked image parameter (not set in this example), and the state-linked text parameter ( In this example, there is no setting) and an additional parameter (“[png] :: data: new.png; top: 3; left: 80; width: 36; heigt: 20”) is combined.

  As a result of the combination, the display area parameter is “[div] :: left: 180; top: 460; Width: 190; heigt: 80”, and the state-linked image parameter is “[png] :: width: 190; height: 240; data: btnColor # 190x80.png ”, the state-linked text parameter is“ [text] :: top: 20; textAlign: center; fontSize: 20; colorGroup: btn1 ”, and the additional parameter is“ [png] :: data: new.png; top: 3; left: 80; width: 36; heigt: 20 ”. Note that the extended object selector (“[div]”, “[png]”, and “[text]” ”) is displayed in the ECMAScript file for the parameters described in the display area parameter, state image parameter, and state-linked text parameter. 57 is added by the script described in 57, an appropriate element is allocated by the element allocation management unit 57b, and the parameter value is applied to the element. Therefore, the description of the selector is prohibited for the parameters described in the display area parameter, the state-linked image parameter, and the state-linked text parameter of the parameter file. This is because the parameter value synthesis process between the layout BTB 59 and the template BTB 61 is performed. This is a device for simplification. On the other hand, an extended object selector can be freely described in the additional parameter.

  Since the layout BTB 59 and the template BTB 61 are divided in this way, if setting information frequently used in advance is generated as the template BTB 61, the layout BTB 59 is set (ie, the layout BTB 59 as shown in FIG. 5). When the manuscript creator inputs the edit screen 101), the labor can be reduced.

  After the combination of the layout BTB 59 and the template BTB 61 is performed, the contents of the color group BTB 63 and the color master BTB 65 are further added to the parameters by the parameter BTB analysis / application unit 57a. The color group BTB63 defines information for specifying the character display color (state interlocking color) of the focus item, and is set as the value of the color group ("colorGrput" specified in the layout BTB59 or the template BTB61. Information) (color set name of each state) is defined (see FIG. 18A). In the color master BTB 65, foreground color, background color, and the like of each color set are defined (see FIG. 18B).

  FIG. 18A represents the color group BTB63 in a tabular form, and each record is composed of a color group name and color sets 1-6. The color group name is a name that can uniquely identify a record, and is a name that can be specified from the layout BTB 59 or the template BTB 61. The color set 1 is designated with a color set name relating to a color that is not in focus, the color set 2 is designated with a color set name relating to a focused color, and the color set 3 is in a determined state. A color set name for a color is specified. The color set 4 is designated with a color set name relating to the selected color, the color set 5 is designated with a color set name relating to the invalid color, and the color set 6 is in a state other than the above. A color set name for a color is specified.

  FIG. 18B represents the color master BTB 65 in a tabular format, and each record includes a color set name, a foreground color, a gray scale 1, a gray scale 2, and a background color. . The color set name is a name that can uniquely identify a record, and is a name that can be specified from the color group BTB. As the foreground color, a palette number of a color corresponding to a color-index in CSS (a palette number defined in a CLUT file in the ARIB standard) is designated. In the CLUT file, the R value, G value, B value, and transmittance of each palette number are defined. For grayscale 1, a palette number of a color corresponding to grayscale-color-index in CSS is designated, and a palette number of a color on the foreground color side that is an intermediate color between the text color and the background color is designated. For gray scale 2, a palette number of a color corresponding to grayscale-color-index in CSS is designated, and a palette number of a color on the background color side that is an intermediate color between the character color and the background color is designated. As the background color, the palette number of the color corresponding to the background-color-index in CSS is designated, and the palette number of the background color is designated.

[Effect of the embodiment]
With the BCML set 51 as described above, the layout and behavior on the data broadcast screen can be changed by editing the parameter file (layout BTB59, template BTB61, color group BTB63, and color master BTB65). In addition, the editing work can be performed on the Web screen provided by the document creator from the CMS server 17. Therefore, the layout of the data broadcast screen is changed only by grasping information to be input on the Web screen by the manuscript creator, that is, without knowing advanced knowledge such as BCML, BML, and ARIB standards. be able to. In addition, since the layout and behavior information on the data broadcast screen are collected in the parameter file, debugging work when there is a problem in the data broadcast screen is easy.

  In addition to the parameter file, the CMS server 17 outputs an XML file equivalent to the parameter file. Therefore, by using JAVAScript or the like corresponding to the XML file, the author can use an expensive data broadcasting browser. Even if it is not prepared, a general-purpose Internet browser can be used to test the data broadcasting screen. That is, the data broadcasting screen can be edited at a reasonable cost.
