Description

  The present invention relates to a program production device and a program production program, and more particularly to a program production device and a program production program for efficiently producing a program.

  Conventionally, in program production, it is necessary to perform various settings such as setting of information (material) transmitted to the viewer by the program creator and setting of the production of the program using the material. Therefore, a technique for producing an efficient program is disclosed. For example, a program producer using an object-based description language capable of producing a program on a PC such as TVML (TV Program Making Language). To reduce the burden and improve efficiency.

  Here, TVML is a description of video and audio of a TV program divided into material and script (production contents). If a program script is described, it can be read by software running on a personal computer. It can be immediately viewed (presented) as a television program. In addition, since the TVML language can be read in a meaningful form as text when data contents are viewed, and is highly readable, it is easy to create TVML by directly creating a TVML script with a text editor or the like. it can.

  When creating a program, if editing the program configuration or adding a new configuration in the middle of the program, the script information must be recreated from the beginning, or the program script information can be directly There was only a method of changing the program manually, and there was a problem that it was not possible to respond quickly to changes in the program structure. In particular, there is a problem that it takes time and effort to produce a program because it is necessary to set information related to the production in detail through manual operation.

  Therefore, recently, a technique has been disclosed that can easily produce a program by combining existing configurations (style sheets) when generating program script information in order to improve efficiency in program production (for example, , See Patent Document 1).

In Patent Document 1, when creating a script for a program, it is possible to create a program script by combining a plurality of configurations (style sheets) that form a template, rather than creating all the configurations from one. Thereby, the time required for program production can be shortened.

  However, the above-described conventional technique discloses a technique relating to a style sheet description method and a conversion method, but does not describe how to edit the effect style sheet itself.

  Here, when creating a program, edit the production style sheet in a state in which the program is converted into a script that can be executed on the software by using the script information and the style sheet, and after further conversion, the screen is displayed again. The work of confirming the editing result is repeated until the desired program is produced. That is, when editing an effect style sheet such as a TV program, it is necessary to edit while viewing the video of the output program.

  However, since the style sheet source code exists only before the script is output, the script cannot be edited while watching the program output by the script.

  In addition, as another method, even when preparing a debugging content part in advance and editing while watching the program created with the output script, the output script is already after conversion with the style sheet, The change could not be quickly reflected (feedback (reverse conversion)) on the base information (source code, etc.) of the style sheet.

  Furthermore, in order to reflect the edited style sheet results in the script information and production style sheet that is the basis of the produced program, the same contents edited by the program producer in the style sheet are edited with a text editor or the like. There is a need to. This places a burden on the producer, and may cause content different from the content edited on the style sheet to be reflected in the information on which the produced program is based.

  The present invention has been made in view of the above-mentioned problems, and is intended to efficiently produce a program by quickly and accurately reflecting the content of the editing result at the time of production of the program. An object is to provide a program production device and a program production program.

  The invention described in claim 2 is characterized in that the style sheet converting means outputs a style sheet in which source code information included in advance in the effect style sheet is embedded as intermediate output data.

  According to the second aspect of the invention, the program producer can easily grasp which information of the script information or the effect style sheet is changed by checking the source code. Further, in one intermediate output file, both the script information and the effect style sheet can be changed and edited at the same time.

  In the invention described in claim 3, when the source code is changed, the intermediate output data editing means changes at least one of the script information and the effect style sheet based on the changed position. It is characterized in that it is reflected in the contents.

  According to the third aspect of the present invention, the script information and the effect style sheet can be changed quickly and accurately based on the changed position. Further, in one intermediate output file, both the script information and the effect style sheet can be changed (edited) at the same time.

  According to a fourth aspect of the present invention, the intermediate output data editing means, when the position of the source code changed in the intermediate output data is within a tag included in the source code, the contents of the effect style sheet Is reflected in the contents after the change.

  According to the fourth aspect of the present invention, the effect style sheet can be quickly and accurately changed based on the changed position. Further, the program producer can easily grasp which information of the script information or the effect style sheet is to be changed depending on whether or not the changed portion is within the tag.

  According to a fifth aspect of the present invention, the intermediate output data editing means, when the position of the source code changed in the intermediate output data is outside the tag included in the source code, It is reflected in the contents after the change.

  According to the fifth aspect of the present invention, the script information can be changed quickly and accurately based on the changed position. Further, the program producer can easily grasp which information of the script information or the effect style sheet is to be changed depending on whether or not the changed portion is within the tag.

  The invention described in claim 6 causes a computer to execute a program production process for producing a program by using script information indicating the configuration, order or contents of the program and an effect style sheet indicating an effect or an effect to be given to the program.

In addition, program production can be realized efficiently at low cost without requiring a special device configuration. Moreover, program production can be easily realized by installing the program.

  According to the present invention, a program can be produced efficiently.

  Hereinafter, a preferred embodiment of a program production apparatus and a program production program according to the present invention having the above-described features will be described in detail with reference to the drawings. In the present embodiment, TVML is used as an example of a script used for production and presentation of a program. Note that the present invention is not limited to this, and the present invention can also be applied using an expression format other than TVML.

  FIG. 1 is a diagram showing an example of a schematic configuration of a program production apparatus according to the present invention. The program production apparatus 10 shown in FIG. 1 includes a style sheet conversion unit 11, a storage database 12, an intermediate output data editing unit 13, a reproduction unit 14, and a final output unit 15.

  The style sheet conversion means 11 extracts script information and presentation style sheets necessary for production of a desired program from the storage database 12 in which at least one script information and presentation style sheets are stored, and extracts the extracted script information. Based on this, the production style sheet is converted.

  Here, the script information is information indicating the configuration, order or contents of a program. The style sheet is a style sheet (production style sheet) in which only a production part is separated in order to divide a script describing a flow of a program structure particularly in a television program into a script part and its content part.

  Further, the style sheet conversion means 11 outputs intermediate output data in which information indicating which template was used for conversion is embedded in the conversion by the effect style sheet. In the intermediate output, information such as which template is used for which part, and information on which debugging content information (description) is used as script information is inserted.

  Note that the style sheet conversion means 11 outputs intermediate data in which the information of the sword code is embedded, instead of converting into an output script at the time of conversion by the style sheet. The program producer can edit the source code by determining which part has been edited by editing the source code.

  The style sheet conversion unit 11 outputs the converted intermediate data to the intermediate output data editing unit 13. The intermediate output data editing unit 13 edits a program based on the intermediate output data obtained by the style sheet conversion unit 11.

  The intermediate output data editing means 13 generates a script for reproducing the program and outputs it to the reproducing means 14 when editing the program. Further, when changing (editing) the content of the program reproduced by the reproducing unit 14, the intermediate output data editing unit 13 performs editing by an editor or the like for editing the intermediate output data. That is, the program producer who edits the output script edits the intermediate output data while viewing the screen to be played back on the playback means 14.

  Here, when the edited program is played back by the playback unit 14, the intermediate output data editing unit 13 generates a playback script and stores the changed portion of the edited intermediate output data in the storage database 12. The script information that is the basis of the program to be produced is reflected (feedback) in the relevant part of the production style sheet.

  As a result, the contents edited using the intermediate output data can be quickly and accurately reflected on the information that is the basis of the produced program. Further, since the intermediate output data shows information with the source code remaining, the program producer can easily grasp which information has been changed.

  Note that the timing of reflecting the change contents using the intermediate output data in the information that is the basis of the produced program may be the time when the reproduction means 14 reproduces during the change (editing) as described above. When editing with the intermediate output data ends, that is, when the intermediate output data editing unit 13 outputs the final output unit 15 to the final output unit 15, processing may be performed to reflect the information.

  Further, the intermediate output data editing means 13 outputs the intermediate output data of the program produced by the program producer according to the above-described content to the final output means 15. The final output unit 15 generates a script from the intermediate output data obtained by the intermediate output data editing unit 13 and outputs the script.

  As a result, when the program creator changes the content of the program, it determines from the information embedded in the intermediate output data which template of the style sheet is changed or which part of the content information for debugging. be able to. Therefore, feedback can be made based on the edited content of the style sheet source code or debugging content information as appropriate.

  Here, the program production in the program production apparatus 10 can be realized by using the general-purpose computer or the like and having the above-described functions by software or the like. Specifically, computer processing in the above-described program production is performed by an input form using a GUI (graphical user interface).

  In other words, as described above, the program production device 10 can perform program production according to the present invention with a dedicated device configuration, but generates an execution program that can cause a computer to execute the processing in each configuration. For example, the program production in the present invention can be realized by installing the program in a general-purpose personal computer, a workstation or the like.

<Hardware configuration>
Here, an example of a hardware configuration of an executable computer in the present invention will be described with reference to the drawings. FIG. 2 is a diagram illustrating an example of a hardware configuration capable of realizing program production according to the present invention.

  The input device 21 has a pointing device such as a keyboard and a mouse operated by a user, and inputs various operation signals such as execution of a program from the user. The output device 22 has a display for displaying various windows and data necessary for operating the computer main body for performing the processing according to the present invention, and displays the program execution progress, results, and the like by the control program of the CPU 26. can do.

  Here, in the present invention, the execution program installed in the computer main body is provided by the recording medium 28 such as a CD-ROM, for example. The recording medium 28 on which the program is recorded can be set in the drive device 23, and the execution program included in the recording medium 28 is installed in the auxiliary storage device 24 from the recording medium 28 via the drive device 23.

  The auxiliary storage device 24 is a storage means such as a hard disk, and stores the execution program according to the present invention, the control program provided in the computer, the script information stored in the storage database 12 and the effect style sheet, and the like. Input / output can be performed accordingly.

  The CPU 26 performs processing of the entire computer, such as various operations and data input / output with each hardware component, based on a control program such as an OS (Operating System) and an execution program read and stored by the memory device 25. Each process can be realized by controlling the above. Various information necessary during the execution of the program can be acquired from the auxiliary storage device 24 and can also be stored.

  The network connection device 27 acquires an execution program from another terminal connected to the communication network by connecting to a communication network or the like, or an execution result obtained by executing the program or an execution in the present invention The program itself can be provided to other terminals.

  With the hardware configuration as described above, it is possible to realize program production efficiently at a low cost without requiring a special device configuration. Further, by installing the program, it is possible to realize a program production process and the like described later.

<Specific Examples>
Next, a specific example using the above-described program production apparatus 10 will be specifically described. In this embodiment, the production style sheet is XSLT (XML Style Language Transformations) and the final output is a TVML script, but the production style sheet format and final output form in the present invention are not limited to this.

  FIG. 3 is a diagram showing an example of an editing screen for producing (editing) a program according to the present invention. In the present embodiment, the editing screen 30 displayed on an output device such as a display has an effect style sheet display area 31, a debug content information display area 32, a script display area 33, and a program playback area 34. It is configured as follows. Note that the arrangement position and size of each display unit, the number of screens (windows), and the like of the editing screen example illustrated in FIG. 3 are not limited thereto.

  The effect style sheet display area 31 displays the source code of the effect style sheet used when producing a desired program. The effect style sheet display area 31 is reproduced in the “conversion” button for converting the style sheet, the “reproduction” button for reproducing the edited contents in the program reproduction area 34, and the program reproduction area 34. It has at least one button section among a “stop button” for stopping a program and a “pause” button for pausing program reproduction. Note that the types and positions of the buttons are not limited to this in the present invention. For example, a “rewind” button, a “fast forward” button, or the like for the program being played in the program playback area 34 may be provided. .

  The effect style sheet display area 31 has a function as a text editor, and the program producer can directly edit the description contents of the effect style sheet.

  Here, an example of an effect style sheet will be described. FIG. 4 is a diagram illustrating an example of an effect style sheet. The effect style sheet shown in FIG. 4 is an effect style sheet for a news program. Note that the number of lines (01) to (32) is added to the left side of FIG. 4 in order to explain the source code on the style sheet in this embodiment.

  In FIG. 4, lines (04) to (14) describe preprocessing of the effect part of the effect style sheet by XSLT, and lines (16) to (18) indicate the “video” template. The lines (20) to (22) indicate a template of “supertitled super (super)”, and the lines (24) to (26) indicate “comments”. A template is shown, and the (28) to (30) lines show a “title” template. Note that the production template is a template for general use, and at this point, no specific content is set for a specific video image, a caption by a supertitle, a CG character, or the like.

  The debug content information display area 32 is an area for displaying script information, and sets and displays a work directory. The debug content information display area 32 has a function as a text editor, and the program producer can directly edit the script information as debug content information.

  Here, the set concrete video image, the caption by the caption super, the CG character, etc. are added to the effect style sheet, and the intermediate output data and the final output data are output.

  FIG. 5 is a diagram showing an example of the debugging content description XML which is the script information. The script information shown in FIG. 5 includes contents corresponding to specific templates (video, super, comment, title) included in the effect style sheet shown in FIG. 4 in the tags in the (04) to (07) lines. is described.

  For example, FIG. 5 shows that the <video> tag uses the “shinkansen.mpg” MPEG file. Similarly, the <super> tag, the <comment> tag, and the <title> tag are also supported. The character information to be written is described. The debug content information display area 32 can display and change information described in these tags.

  The debug content information display area 32 can display not only the XML display but also a script file in XML format such as ASS (Ape Show Script) as shown in FIG. The input socket indicating the event type and the value (data contents) indicated by the information can be newly added, deleted, rearranged, and changed (edited).

  The script display area 33 can display the above-described intermediate output data and can also display an on-air TVML script (final output) for reproducing a final program.

  The script display area 33 has a function as a text editor, and the content information can be directly edited by the program producer. The program producer changes and edits the content of the intermediate output data displayed in the script display area 33, and the changed content is reflected in the effect style sheet and script information by the changed position. The contents are newly output to the effect style sheet display area 31 and the debug content information display area 32. Further, after the editing is completed, final final output data is displayed in the script display area 33.

  Here, FIG. 6 is a diagram illustrating an example of the intermediate output data. FIG. 7 is a diagram illustrating an example of final output data. The intermediate output data shown in FIG. 6 is an intermediate output having a format in which information on the template of the production style sheet and information (content information for debugging) of content description XML (source code) for debugging are embedded. Therefore, when the program producer changes the contents, it is possible to easily grasp which information is changed among the script information or the information described in the effect style sheet.

  Further, at the time of program production, the edited contents obtained by editing the intermediate output data can be reflected (feedback) on the information that is the basis of the program produced quickly and accurately.

  The program playback area 34 plays back a program composed of an on-air TVML script for final output. That is, the program producer can view a program operated by the TVML player by the program production device 10.

  Here, the TVML player is software that reads a program script described in TVML and outputs program video and audio in real time. With the TVML player, for example, a studio shot can be generated by real-time CG, and a CG character appearing in the CG studio set can speak the speech described in the TVML script with synthetic speech, and can be displayed. Also, title display, superimpose, etc. can be performed.

  The program producer can easily grasp the description corresponding to the changed portion by the intermediate output data while checking the contents of the program reproduction area 34, and can edit it quickly. Thereby, a program can be produced efficiently.

  Here, a specific example of the variation by changing the description content will be described. For example, “character: talk (name = master, text = ″ <value-of select =“ title ”order =” 3 ”> newsday </ value> described in the (05) and (06) lines of FIG. . -of> is the time "a part of)", "character: talk (name = caster, text =" Hello, <value-of select = "title" order = "3"> News Today </ value-of > This is the time ") and when the program creator has changed is the user," Hello, "inserted where the will of the presentation style sheets <xsl: template match =". ape "> in the template (FIG. 4 (04 ) To (14) line). Therefore, the intermediate output data editing means 13, (08) of the presentation style sheet shown in Figure 4, (09) th row of the "character: talk (name = caster, text =" Hello, <xsl: value-of select = "Title" /> time. ")".

  Similarly, "Character: talk (text =" <value-of select = "." Order = "2">) at the line (22) and (23) in FIG. </ Value-of> "), the program producer will be" character: talk (text = "<value-of select =". "Order =" 2 "> Finally, a Shinkansen station will open at Shinagawa Station. </ Value-of> "), it can be determined that the changed part is a parameter on the (06) line of the debug content description XML. Therefore, the intermediate output data editing means 13 is shown in FIG. This part will be changed to “<comment> Finally, the Shinkansen station has opened in Shinagawa </ comment>”.

  As described above, according to the present embodiment, information indicating which template was used for conversion by the effect style sheet, that is, information on the template of the effect style sheet, and XML for content description for debugging ( Intermediate output data in which the source code information is embedded is generated. Also, information such as which template is used for each part of the output and which debugging content description is used is inserted into the intermediate output data.

  Further, a program producer as a user who edits the output script may perform editing for producing a desired program on the intermediate output data while viewing the reproduced screen as shown in FIG. it can. In this way, by changing on the intermediate output data, the program producer can grasp from the embedded information which template of the style sheet is changed or which content information for debugging. Can do. Further, the program production apparatus 10 can reflect (feedback) the source code of the style sheet or the content information for debugging as appropriate. Thereby, a program can be produced efficiently.

<Program production process>
Next, an example of a program production process procedure using an execution program (program production program) in the present invention will be described with reference to a flowchart. FIG. 8 is a flowchart showing an example of a program production processing procedure.

  First, script information and production style sheets necessary for producing a desired program are input (S01). Next, the effect style sheet is converted from the input script information (S02), and intermediate output data in which information indicating which template was used for conversion is generated when the effect style sheet is converted (S03). ). At this time, an on-air script for reproducing the program at the same time may be generated.

  Next, the program is reproduced (S04), and it is determined whether it is necessary to change (edit) the contents of the program (S05). Here, when it is necessary to change the contents (YES in S05), a desired change portion is changed in the intermediate output data (S06). At this time, an on-air script for reproducing the program at the same time may be generated.

  Further, the contents changed in S06 are reflected in the corresponding part of the script information and the effect style sheet (S07). In the processing of S07, the script information or the effect style sheet may be reflected in the corresponding portion of any corresponding data.

  Next, after the processing of S07 is completed, the program returns to S04 to reproduce the program. That is, the processes of S04 to S07 are repeated until it is no longer necessary to change the contents of the program, and if it is not necessary to change (NO in S05), an on-air script as final output data is generated and output. (S08), the program production process is terminated.

  As a result, the contents of the edited result at the time of program production can be quickly and accurately reflected (feedback) on the base information, thereby efficiently producing the program. In addition, program production can be realized efficiently at low cost without requiring a special device configuration. Moreover, program production can be realized by installing a program.

  Note that the processing procedure of FIG. 8 is an example, and the present invention is not limited to this. For example, in the above-described processing procedure, after changing the content of the intermediate output data, the changed content is the basis of the program that has been produced. 8 is reflected in the script information and the effect style sheet, but the process of S07 in FIG. 8 is not performed, and the final process is performed in the same way as S07 when the final data is output in S08. It may be reflected (feedback) in the script information and the production style sheet.

  As described above, according to the present invention, a program can be produced efficiently. Specifically, it becomes possible to change the content of the script and the content of the production style sheet while watching the program that is actually output, and the production efficiency of the program can be greatly improved.

  In the present invention, intermediate output data in which information indicating which template is used for conversion is generated in the conversion using the effect style sheet. In addition, information such as which template is used for each part of the output or which debugging content information (description) is used is inserted into the intermediate output data. In addition, a program producer as a user who edits the output script can edit it on the intermediate output while viewing the reproduced screen.

  In this way, in the present invention, by editing (changing) a program on the intermediate output data, the program producer can determine which template of the style sheet the changed portion is, or which part of the contents information for debugging. Can be grasped from the embedded information. Therefore, the source code of the style sheet or the content information for debugging can be appropriately fed back and changed. Thereby, a program can be produced efficiently.

  Note that the program production efficiency according to the present invention can be improved, for example, by applying it to a conventional TV4U (TV for You) system or the like.

  Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment, and various modifications, within the scope of the gist of the present invention described in the claims, It can be changed.
