For example, as dependency relationship with other media data stored in the media data storage unit 101, The file name of the parent media and the file name of the child media are described. In the dependency relationship, the parent medium may be configured to have a plurality of child media.

  Time synchronization information 203 and presentation information 204 are display conditions for displaying media data as digital content. The time synchronization information 203 describes the display time and display time of the media data. For example, the display time indicates the time that the display is maintained after the display is started, and the display time corresponds to the display time of the parent media. The display start time is shown.

  The presentation information 204 describes the display method and display area of media data. The display method indicates a display operation of media data. For example, the display method is a method in which the media data is paused when digital content is displayed, or a method in which the media data is blinked. The display area indicates a position where media data is displayed in the display of digital content.

  Here, regarding the processing operation of the authoring apparatus 100, a component object generation method, a component object editing method, and a digital content construction method will be described.

  When the dependency information is set by the component object setting unit 103, the presentation information editing unit 105b generates a presentation information input screen and displays it via the display unit 110 (step ST110). When presentation information is input from the user (external), the presentation information editing unit 105 b outputs the input presentation information to the component object setting unit 103.

  When the presentation information is input via the presentation information editing unit 105b (step ST111), the component object setting unit 103 sets the presentation information in the component object (step ST112).

  If there is no setting end instruction from the user after the process of step ST109 or step ST112 (step ST113 “NO”), the processes from step ST107 and step ST110 are repeated.

  Upon receiving a setting end instruction from the user (step ST113 “YES”), the component element setting unit 103 ends the setting of the dependency information, the time synchronization information, and the presentation information according to the setting end instruction, and the generated component object is Store in the component object storage unit 107 (step ST114). When the component object input by the component element storage unit 107 is stored, the authoring apparatus 100 ends the process of creating and setting the component object (end).

  Next, a component object editing method will be described. The component object editing method is a method of calling and editing a component element created and stored by the above-described component object creation method.

  FIG. 4 shows a method for editing a component object in the authoring apparatus 100. For example, the authoring apparatus 100 starts processing according to a request from the user (external), and a designation screen for designating a component object stored in the component object storage unit 107 is displayed on the component object calling unit 108. To the display means 110 (start).

  When the component object is designated by the user (step ST201), the component object calling unit 108 calls and acquires the component object from the component object storage unit 107, and outputs it to the component element setting unit 103 (step ST201). ST202).

  When the component object setting unit 103 inputs the component element object from the component element object storage unit 107 via the component element object calling unit 108, the set dependency object information, time synchronization information, and presentation information are displayed via the display unit 110. To select it.

  When the dependency information is selected by the user via the component object setting unit 103 (step ST203), the dependency relationship information editing unit 104 displays the set dependency relationship information editing screen via the display unit 110. (Step ST204).

  When the component element setting unit 103 inputs dependency information other than the dependency relationship information set so far from the user via the dependency relationship information editing unit 104 (step ST205), the dependency relationship included in the component element object is input. Information is changed and set (step ST206).

  When the time synchronization information is selected by the user via the component object setting unit 103 (step ST203), the time synchronization information editing unit 105a displays the set time synchronization information editing screen via the display unit 110. (Step ST207).

  When the component synchronization object setting unit 103 inputs time synchronization information other than the time synchronization information set so far from the user via the time synchronization information editing unit 105a (step ST208), the time synchronization information included in the component element object Information is changed and set (step ST209).

  When presentation information is selected by the user via the component object setting means 103 (step ST203), the presentation information editing means 105b displays the set presentation information editing screen via the display means 110 (step ST210). ).

  When the component information setting unit 103 inputs presentation information other than the presentation information set so far from the user via the presentation information editing unit 105b (step ST211), the component object setting unit 103 changes the presentation information included in the component object. (Step ST212).

  If there is no setting end instruction from the user after the above-described steps ST206, ST209, and ST212 (step ST213 “NO”), the processing from step ST203 is repeated.

  After the processing of step ST206, step ST209, and step ST212 described above, the component object setting unit 103 receives a setting end instruction from the user (step ST213 “YES”), and in accordance with the setting end instruction, dependency information, time synchronization information, The editing setting of the presentation information is finished, and the component element that has been edited and set is stored in the component object storage unit 107 (step ST214). When the component object input by the component element storage unit 107 is stored, the authoring apparatus 100 ends the editing and setting process for the component object (END).

Next, a digital content construction method will be described.
The digital content construction method is a method of constructing digital content by converting and combining media data based on component elements.

  FIG. 5 shows a digital content construction method in the authoring apparatus 100. For example, the authoring apparatus 100 starts processing in accordance with a request from the user (external), and a designation screen for designating the component object 200 stored in the component object storage unit 107 is a component object calling unit. 108 is output to the display means 110 (start).

  When the component element object 200 is designated by the user (step ST301), the component element calling unit 108 calls and acquires the component element object 200 from the component element object storage unit 107, and outputs it to the digital content construction unit 109 ( Step ST302).

  When the digital content construction unit 109 inputs the component element 200 via the component object calling unit 108, the digital content construction unit 109 requests media data from the media data calling unit 102 based on the media information 201 of the component object 200, and stores the media data. Media data is input from unit 101 via media data calling means 102 (step ST303). Here, the processing from step ST301 to step ST303 is repeated until all the media data used for the digital content is input from the user. At this time, by selecting and calling the component object 200 in accordance with the purpose of use of the user, it is possible to reconstruct and reset digital content according to the purpose of use of the user.

  When the media data is input, the digital content construction unit 109 generates a dependency relationship between the media data based on the dependency relationship information 202 of the component object 200 corresponding to each media data.

  When the digital content construction unit 109 generates the dependency relationship between the media data, the digital content construction unit 109 generates a digital content timeline based on the time synchronization information 203. In the digital content timeline, for example, the display time and display time of each media data in the digital content are set by arranging the display time and display time of each media data on one time axis.

  When the digital content construction unit 109 sets the digital content timeline, the digital content construction unit 109 converts the media data to match the display method and display area specified based on the presentation information 204 (step ST304).

  The digital content construction unit 109 constructs digital content and outputs it to the display unit 110 by superimposing or combining the converted media data in accordance with the timeline and outputting it (step ST305). Display unit 110 displays the digital content input from digital content construction unit 109 (step ST306).

Here, an example of setting time synchronization information in the component object generation method will be described.
FIG. 6 shows an example of a method for generating the component objects 306 and 307 in the authoring apparatus 100. 6, the configuration of the authoring apparatus 100 is the same as that in FIG. 1, and thus a part of the configuration is omitted.

  As shown in FIG. 6, the media data storage unit 101 stores “video 1” 303, “video 2” 304, and “text 1” 305 as media data. When “video 1” 303 is designated by the user (external) via the component object setting unit 103 (step ST101 in FIG. 3 described above), the media data calling unit 102 receives “video 1” from the media data storage unit 101. "303" is acquired and output to the component element setting means 103 (step ST102).

  Upon receiving “Video 1” 303 from the media data calling unit 102, the component object setting unit 103 acquires the file name “Video 1” and the media type “Video” assigned to “Video 1” 303. Then, media information included in the component object 306 is set (step ST103).

  When the media information is set by the component object setting unit 103, the dependency relationship information editing unit 104 generates a dependency relationship information input screen and displays it via the display unit 110. When the dependency information editing unit 104 inputs from the user (external) that the parent medium is “none” and the child media is “text 1” (dependency relationship information), the dependency information is input to the component object setting unit. It outputs to 103 (step ST104).

  When the component object setting unit 103 inputs that the parent medium is “none” and the child medium is “text 1” (dependency relationship information) via the dependency relationship information editing unit 104 (step ST105), “Parent: none” and “child: text 1” are set as dependency relationship information for the object (step ST106). Here, since “Video 1” 303 is the parent medium, the input of time synchronization information can be omitted.

  Upon receiving a setting end instruction from the user (step ST113 “YES”), the component element setting unit 103 ends the setting of the concept element object 306 corresponding to “video 1” 303 according to the setting end instruction, and generates the generated component element The object 306 is stored in the component object storage unit 107 (step ST114).

  Next, when “text 1” 305 is designated by the user via the component object setting unit 103 (step ST101), the media data calling unit 102 calls “text 1” 305 from the media data storage unit 101. It is acquired and output to the component element setting means 103 (step ST102).

  When the “text 1” 305 is input from the media data calling unit 102, the component object setting unit 103 acquires the file name “text 1” and the media type “text” assigned to the “text 1” 305. Then, media information included in the component object 307 is set (step ST103).

  When the media information is set by the component object setting unit 103, the dependency relationship information editing unit 104 generates a dependency relationship information input screen and displays it via the display unit 110. When the dependency information editing unit 104 inputs from the user (external) that the parent media is “video 1” and the child media is “none” (dependency relationship information), the dependency information is input to the component object setting unit. It outputs to 103 (step ST104).

  When the component element setting unit 103 inputs that the parent medium is “video 1” and the child medium is “none” via the dependency relationship information editing unit 104 (step ST105), the component element object setting unit 103 sets the dependency relationship to the component element 307. As information, “parent: video 1” and “child: none” are set (step ST106).

  When the dependency information is set in the component object setting unit 103, the time synchronization information editing unit 105a generates a time synchronization information input screen and displays it via the display unit 110 (step ST107). When the time synchronization information editing unit 105 a inputs that the display time is “5 seconds” (time synchronization information) from the user (external), the time synchronization information editing unit 105 a outputs the input time synchronization information to the component object setting unit 103.

  When the component object setting unit 103 inputs that the display time is “5 seconds” via the time synchronization information editing unit 105a (step ST108), the component object object 307 displays “display time: 5 as time synchronization information”. Second "is set (step ST109).

  When the component end setting unit 103 inputs a setting end instruction from the user (“YES” in step ST113), the setting of the dependency relationship information and the time synchronization information is ended in accordance with the setting end instruction, and the generated component element object 307 is set as the component. Store in the object storage unit 107 (step ST114).

  In this way, the component object 306 sets that “video 1” 303 has a dependency relationship in which “text 1” 305 is a child medium, and the component object 307 is “text 1”. "305" has a dependency relationship with "Video 1" 303 as a parent medium, and is set to be displayed after 5 seconds from the start of display of "Video 1" 303 as shown in the timeline of FIG.

  Next, an example of setting presentation information in the component object generation method will be described. FIG. 7 shows an example of a method for generating the component objects 406 and 407 in the authoring apparatus 100. Media data is designated and displayed in “Area 1” 409 and “Area 2” 410 in the digital content screen 408. A case where presentation information to be set is set will be described. 7, the configuration of the authoring apparatus 100 is the same as that in FIG. 1, and thus a part thereof is omitted. The same configuration is described with the same reference numerals as in FIG. 1.

  As shown in FIG. 7, the media data storage unit 101 stores “video 1” 303, “video 2” 304, and “text 1” 305 as media data.

When “video 1” 303 is designated by the user (external) via the component object setting unit 103 (step ST101 in FIG. 3 described above), the media data calling unit 102 receives “video 1” from the media data storage unit 101. "303" is acquired and output to the component element setting means 103 (step ST102).

  Upon receiving “Video 1” 303 from the media data calling unit 102, the component object setting unit 103 acquires the file name “Video 1” and the media type “Video” assigned to “Video 1” 303. Then, media information included in the component object 406 is set (step ST103).

  When the media information is set by the component object setting unit 103, the dependency relationship information editing unit 104 generates a dependency relationship information input screen and displays it via the display unit 110. When the dependency information editing unit 104 inputs that the parent medium is “none” and the child medium is “text 1” (dependency relationship information) from the user, the input dependency relationship information is output to the component object setting unit 103. (Step ST104).

  When the component object setting unit 103 inputs that the parent medium is “none” and the child medium is “text 1” (dependency relationship information) via the dependency relationship information editing unit 104 (step ST105), “Parent: none” and “child: text 1” are set as dependency relationship information for the object (step ST106). Here, since “Video 1” 303 is the parent medium, the input of time synchronization information can be omitted.

  When the dependency information is set by the component object setting unit 103, the presentation information editing unit 105b generates a presentation information input screen and displays it via the display unit 110 (step ST110). When the presentation information editing unit 105 b inputs from the user that the display area is “Area 1” 409 on the digital content screen 408 (presentation information), the presentation information editing unit 105 b outputs the input presentation information to the component object setting unit 103.

  When the component element setting unit 103 inputs that the display area is “area 1” 409 via the presentation information editing unit 105b (step ST111), the component object 406 displays “display area: area 1” as presentation information. "Is set (step ST112).

  Upon receiving a setting end instruction from the user (“YES” in step ST113), the component element setting unit 103 ends the setting of the concept element object 406 corresponding to “video 1” 303 according to the setting end instruction, and generates the generated component element The object 406 is stored in the component object storage unit 107 (step ST114).

  Next, when “text 1” 305 is designated by the user via the component object setting unit 103 (step ST101), the media data calling unit 102 calls “text 1” 305 from the media data storage unit 101. It is acquired and output to the component element setting means 103 (step ST102).

  When the “text 1” 305 is input from the media data calling unit 102, the component object setting unit 103 acquires the file name “text 1” and the media type “text” assigned to the “text 1” 305. Then, media information included in the component object 407 is set (step ST103).

  When the media information is set by the component object setting unit 103, the dependency relationship information editing unit 104 generates a dependency relationship information input screen and displays it via the display unit 110. When the dependency information editing unit 104 inputs from the user (external) that the parent media is “video 1” and the child media is “none” (dependency relationship information), the dependency information is input to the component object setting unit. It outputs to 103 (step ST104).

  When the component information setting unit 103 inputs that the parent media is “video 1” and the child media is “none” via the dependency relationship information editing unit 104 (step ST105), the component relationship object setting unit 103 sets dependency information on the component object. “Parent: video 1” and “child: none” are set (step ST106).

  When the dependency information is set by the component object setting unit 103, the presentation information editing unit 105b generates a presentation information input screen and displays it via the display unit 110 (step ST110). When the presentation information editing unit 105 b inputs that the display area is “Area 2” 410 on the digital content screen 408 (presentation information) from the user, the presentation information editing unit 105 b outputs the input presentation information to the component object setting unit 103.

  When the component element setting unit 103 inputs that the display area is “area 1” 410 via the presentation information editing unit 105b (step ST111), the component element 407 displays “display area: area 2” as presentation information. "Is set (step ST112).

  Upon receiving a setting end instruction from the user (“YES” in step ST113), the component element setting unit 103 ends the setting of the dependency information and the presentation information according to the setting end instruction, and the generated component element 407 is used as the component object. Store in the storage unit 107 (step ST114).

  In this way, the component object 406 causes the “video 1” 303 to have a dependency with the “text 1” 305 as a child medium, and the “video 1” 303 is changed to “area 1” 409 on the digital content screen 408. Is set to be displayed. Further, the “text 1” 305 has a dependency relationship with “video 1” 303 as a parent medium by the component object 407, and “text 1” 305 is displayed on the “area” on the digital content screen 408 as shown in FIG. It is set to display in “Area 2” 410 in an area different from “1”.

  Next, an example in which, in the component element editing method, a dependency relationship with a new component element object is set for the set component object and new media data is added as a component to the digital content will be described.

  FIG. 8 shows an example of a component object editing method in the authoring apparatus 100. In FIG. 8, the component object set in FIG. 6 described above is edited and “text 2” 506 is additionally set. The same components as those in FIG. .

  As shown in FIG. 8, the media data storage unit 101 stores “video 1” 303, “video 2” 304, “text 1” 305, and “text 2” 506 as media data.

  The authoring apparatus 100 described above starts the generation process of the component object according to the request from the user (external), and a designation screen for designating the media data is displayed on the display means 110 (in FIG. 3 described above). "start").

  When the “text 2” 506 is designated by the user via the component object setting unit 103 (step ST101), the media data calling unit 102 calls and acquires “text 2” 506 from the media data storage unit 101. Then, the data is output to the component object setting means 103 (step ST102).

  When the “text 2” 506 is input from the media data calling unit 102, the component object setting unit 103 described above acquires the file name “text 2” and the media type “text” assigned to “text 2” 506. Then, the media information included in the component object 509 is set (step ST103).

  When the media information is set by the component object setting unit 103, the dependency relationship information editing unit 104 described above generates a dependency relationship information input screen and displays it via the display unit 110. The dependency relationship information editing unit 104 outputs the input dependency relationship information to the component object setting unit 103 when the user inputs that the parent media is “Video 1” and the child media is “None” (dependency relationship information). (Step ST104).

  When the component element setting unit 103 inputs from the user via the dependency information editing unit 104 that the parent medium is “video 1” and the child medium is “none” (step ST105), the component element setting unit 103 in FIG. As shown in the object 509, “parent: video 1” and “child: none” are set as the dependency relationship information (step ST106).

  When the dependency information is set in the component object setting unit 103, the time synchronization information editing unit 105a described above generates a time synchronization information input screen and displays it via the display unit 110 (step ST107). When the display time is “10 seconds” (time synchronization information) from the user, the time synchronization information editing unit 105 a outputs the input time synchronization information to the component object setting unit 103.

  When the component object setting unit 103 inputs that the display time is “10 seconds” via the time synchronization information editing unit 105a (step ST108), the component object object setting unit 103 displays “display time: 10 as time synchronization information”. Second "is set (step ST109).

  Upon receiving a setting end instruction from the user ("YES" in step ST113), the component element setting unit 103 ends the setting of the dependency information and the time synchronization information in accordance with the setting end instruction, and uses the generated component element object 509 as the component. Store in the object storage unit 107 (step ST114).

  Subsequently, the authoring apparatus 100 starts the editing process of the component object according to the request from the user, and a designation screen for designating the component object stored in the component object storage unit 107 is displayed as the component object. The data is output from the calling unit 108 to the display unit 110 (“Start” in FIG. 4 described above).

  When the component object 306 is designated by the user (step ST201), the component object calling unit 108 calls and acquires the component element 306 from the component element storage unit 107, and outputs it to the component object setting unit 103. (Step ST202).

  When the component object setting unit 103 inputs the component element 306 from the component object storage unit 107 via the component element calling unit 108, the set media information “video 1” “video” and the dependency relationship information “parent” are set. : None ”and“ Child: Text 1 ”are displayed in a selectable manner via the display means 110. At this time, the time synchronization information and the presentation information of the component object 306 are not set, and are displayed blank.

  When the dependency information is selected by the user via the component object setting unit 103 (step ST203), the dependency relationship information editing unit 104 displays the set dependency relationship information editing screen via the display unit 110. (Step ST204).

  When the component element setting unit 103 inputs that the child media is text 2 (dependency relationship information) via the dependency relationship information editing unit 104 from the user (step ST205), the component element setting unit 103 has already been set in the component element object 306. Dependency information of “parent: none” and “child: text 1” are added and set as “child: text 2” (step ST206).

  Upon receiving a setting end instruction from the user (“YES” in step ST213), the component element setting unit 103 ends the editing setting of the media information, the dependency relationship information, the time synchronization information, and the presentation information according to the setting end instruction. The component object 507 after editing and setting the object 306 is stored in the component object storage unit 107 (step ST214). When the component object storage unit 107 stores the component object 507, the authoring apparatus 100 ends the editing and setting process of the component object (END).

  Here, the description of the component object 307, 509 is not changed when the component object is edited, and thus the description thereof is omitted. However, in the case of editing, the component object 307, 509 is similar to the component element 306 described above. The edited component objects 508 and 509 are stored in the component object storage unit 107. In this way, the component object objects 507, 508, and 509 are reset in the component element object storage unit 107 as shown in FIG.

  The component object 508 and the component object 509 are both dependent on “Video 1” 303 as a parent medium, and only the display time is different. Therefore, the component object 307 is copied, edited, and configured. The element object 509 may be set.

  When copying and setting, the component object 307 is called and copied by the processing from step ST201 to step ST203 described above, the media information “text 1” of the copied component object is changed to “text 2”, and the time The synchronization information “display time: 5 seconds” is changed to “display time: 10 seconds”, and the component object 509 is edited and set.

  In this way, the component object 509 is generated, and the component object 306 is edited and the component object 507 is reset, so that “text 2” is displayed 10 seconds after the display start of the “video 1” 303. The setting of displaying 506 can be easily edited and added.
