  As in the conventional technology described above, when capturing a screen during broadcasting and transmitting it by e-mail or FTP, it has been troublesome to capture and transmit all the contents.

  In addition, when transmitting a received TS, the amount of data is large, so a dedicated TS line or IP line is prepared and transmitted in advance, and this is taken into a digital broadcast receiver and executed to confirm viewing. For this reason, it has been expensive and time-consuming to prepare a dedicated TS line or IP line.

  Further, when recording and mailing on a recording medium such as a D-VHS or a hard disk, it takes time to record on the recording medium or to input and execute it on a digital broadcast receiver. In addition, this method has a problem that viewing cannot be confirmed immediately after broadcasting.

  The technology described in Patent Document 1 generates BML content generated for a terminal separately from the data broadcast to be broadcast so that the terminal can view the data broadcast received via the network without any problem. Is received by the terminal and viewed, the broadcast data broadcast was not viewed. When BML content of data broadcasting is acquired through a network and viewed, the location for storing the BML content is different from when it is received via a broadcast wave. There was a problem that it had to do and cost and time and effort.

  Therefore, the problem to be solved by the present invention is to provide a technology that allows a user to immediately view and confirm the content of the broadcast data broadcast without trouble and cost even outside the broadcast area.

  An eighth invention for solving the above-described problem is a program for confirming transmission of a data broadcast, wherein the program causes the transmission confirmation device to store the content of the broadcast data broadcast in a storage unit; When the content of the data broadcast is stored in the storage unit, a process for generating a link for executing the stored BML document of the data broadcast is executed.

  According to the present invention, there is an effect that it is possible to view and confirm the content actually broadcast even if it is out of the broadcast area without taking time and cost.

  In addition, there is an effect that it is possible to view and confirm the content actually broadcasted without passing much time from the broadcast.

  In addition, there is an effect that the content of the broadcast data broadcast can be viewed without any problem on a terminal connected to the network.

  Details of the present invention will be described below. In the following description, BML (Broadcast Markup Language), which is a standard for data broadcasting, will be described as an example of data broadcasting content, but this is not restrictive.

A first embodiment of the present invention will be described.
FIG. 1 is a schematic diagram of the present invention.

  This system includes a plurality of broadcasting stations 1 (1-1 to 1-n), a plurality of BML receiving apparatuses 2 (2-1 to 2-n), a BML server 3, and a digital broadcasting receiver 4. . The BML receiver 2, the BML server 3, and the digital broadcast receiver 4 are connected to each other via a network (Internet, LAN, etc.). In this embodiment, the case where the BML receiving device 2 and the BML server 3 are configured as separate devices will be described. However, the BML receiving device 2 and the BML server 3 may be configured as a single device. A plurality of BML servers 3 may be configured.

  The broadcast station 1 sends out a data broadcast that has been converted to a TS (Transport Stream), as in a normal broadcast station.

  The BML receiver 2 receives a data broadcast from a broadcasting station that can be received by the BML receiver 2. Then, the BML content is extracted from the TS of the received data broadcast, and the BML content module configuration is converted into a folder configuration. Then, the BML content converted into the folder structure is generated with a folder name indicating the broadcast date and time (broadcast reception time) in a predetermined area (folder) for each broadcast station of the BML server 3, and the folder Upload to. Normally, various types of data (module resources, etc.) of BML contents are configured in the order of modules and resources for each component. Therefore, the various data of the BML content uploaded to the BML server 3 is configured as a folder in the order of components, modules, and resources for each broadcast date and time as shown in FIG. There is also a configuration in which the module itself is handled like a resource.

  In this specification, a description will be given using a case where a folder with a folder name indicating the broadcast date and time is generated and uploaded below the folder assigned to each broadcast station, but this is arbitrary, for example, broadcast A format in which a folder with a folder name indicating a month, a broadcast start date and the like is generated and uploaded may be used.

  The BML receiving device 2 is a timing for storing the BML content in the BML server 3, but any timing may be used, but from the viewpoint of confirming the transmission of the BML content of the broadcasted data broadcast, the carousel DII message It is preferable to upload the data when the version of the event message is updated or when a new DII message or event message is received, because it is easier to check whether the event message can be viewed after the update or new reception. In this case, the BML receiver 2 determines whether the carousel DII message has been upgraded or received a new DII message, whether the event message version has been updated or a new event message has been received. A monitoring unit to be monitored is configured. Further, when the monitoring unit detects that the carousel DII message has been upgraded or received a new DII message, the updated carousel DII message or only the new DII message is uploaded. There may be. Further, when it is detected by the monitoring unit that an upgraded event message or a new event message has been received, information indicating the received event message is recorded as a log, and the recorded information is viewed. Accordingly, the content of the upgraded event message or the content of a new event message may be confirmed.

  As shown in FIG. 3, the BML server 3 includes a reception unit 201, a conversion unit 202, and a storage unit 203. Further, although not shown in the figure, a control unit that executes various operations of the BML server 3 is included.

  The receiving unit 201 receives BML content transmitted from the BML receiving device 2.

The conversion unit 202 searches for a correction location from the BML document included in the BML content received by the reception unit 201, rewrites the correction location, and stores it in the storage unit 203. If the BML content of the data broadcast that is normally broadcast is stored in the storage unit 203 as it is and the BML content is executed, it cannot be executed or displayed on the screen. In general, BML content resources (images, scripts, binary tables, etc.) of data broadcasts broadcasted by a broadcasting station are stored in a predetermined memory such as a content memory or an nvram in a digital broadcast receiver according to the type of the resource. Since it is determined to be stored in the area, resources (images, scripts, binary tables, etc.) and module references in BML documents, transition destinations to other BML documents, and acquisition and storage destinations of various data This is because the designation destination such as is a memory in the digital broadcast receiver, and is not a designation destination corresponding to the storage unit 203 in which the resources and modules are stored. For this purpose, the conversion unit 202 allows the digital broadcast receiver 4 to view the BML content of the data broadcast stored in the BML server 3 via the network. Change the designation destination in the descriptive text, such as the transition destination and the acquisition / save destination of various data.
As described above, these designated destinations are converted in correspondence with the storage unit 203. However, a place accessible by the digital broadcast receiver 4 may be designated.

  FIG. 4 is a table showing an example of correction by the conversion unit 202. The conversion unit 202 stores resources and modules as designation destinations in a descriptive sentence such as a reference destination of a resource or module in a BML document, a transition destination to another BML document, or an acquisition destination or storage destination of various data. Change to the specified destination corresponding to the storage unit. Further, instead of changing only the designation destination, a part of the BML document including such a part may be rewritten. It should be noted that all the specified destinations in the BML document may be changed, but the conversion unit 202 may be set to change only the portion where data broadcast transmission is desired to be confirmed.

  The storage unit 203 stores BML contents uploaded by each BML receiving device 2 and BML documents rewritten by the conversion unit 202. In addition, the storage unit 203 stores transmission confirmation BML content and various programs for confirming the converted BML document.

  The digital broadcast receiver 4 accesses the BML server 3 and executes the BML content stored in the BML server 3 to view the broadcast data broadcast in order to check the broadcasted data broadcast via the network. It is a device to check. The digital broadcast receiver 4 may be a PC terminal or a portable terminal as long as it can execute BML content, and can receive a data broadcast broadcast in the broadcast area. It does not have to be. However, when the conversion unit 202 converts the designation destination described in the BML document into nvram or the like in the digital broadcast receiver 4, the digital broadcast receiver 4 is a content that replaces the content of the broadcasted data broadcast. Must be configured so that necessary information can be held in its own nvram or the like via a broadcast wave, a network, or manually.

  Next, the operation in this embodiment will be described with reference to FIG. Here, a case where a BML document is converted when BML content is stored in the BML server 3 will be described. However, a configuration may be adopted in which conversion is performed at an arbitrary timing after the BML document is stored once.

  The BML receiver 2 receives the data broadcasting TS broadcast from the broadcasting station 1 (step S1). Then, the BML content is extracted from the TS, converted into a folder structure, and then uploaded to a predetermined folder of the BML server 3 via the network, that is, a folder assigned to the broadcasting station that broadcasts the data broadcast in this embodiment ( Step S2). If the BML receiving device 2 is configured to upload when the carousel DII message version is updated or when a new carousel DII message is received, this step S2 is repeated. Similarly, when the event message is upgraded or when a new event message is received, the information indicating the received event message is recorded as a log, and this step S2 is repeated.

  The BML server 3 receives the transmitted BML content at the receiving unit 201. In the BML document in the received BML content, the conversion unit 202 searches the BML document for a correction location designated in advance (step S3). When the correction location is searched, the correction location is determined in advance. The correction contents are rewritten (step S4). In the case of a configuration in which a part of a BML document including such a part is rewritten instead of changing only the designation destination, the correction part may be searched and rewritten by performing a binary comparison.

  The BML content and the rewritten BML document are stored in the folder of the corresponding broadcasting station (step S5). Then, step S3 to step S5 are repeated until all the corrected portions are converted (step S6).

  Next, an operation for confirming the BML content stored in the BML server 3 will be described. Note that an access BML document (access program) for the digital broadcast receiver 4 to access the BML server 3 via the network is received by the digital broadcast receiver 4 via the broadcast wave or arbitrarily stored by the user. Therefore, the description will be made assuming that the digital broadcast receiver 4 already stores the digital broadcast. A transmission confirmation BML document (transmission confirmation program) for executing BML content including the BML document converted by the conversion unit 202 is stored in a predetermined folder of the storage unit 203 of the BML server 3 by the user, for example, in FIG. As shown, “top.bml” is stored below the folder “bml”, and further down the folder assigned to each station, for example, “atv_list.bml” in the case of atv. To do. In the following description, when the transmission confirmation BML document “top.bml” is executed, a screen for selecting a station to be viewed is displayed as shown in FIG. 6A, and the station to be viewed is selected. Then, for example, a transmission confirmation BML document “atv_list.bml” in the downstairs folder for each station is executed, and a screen as shown in FIG. 6B is displayed, and further confirmation of transmission of the data broadcast is performed. A description will be given using a configuration in which the BML content corresponding to the selected date / time is executed when the desired date / time is selected. However, when the content to be viewed and confirmed is selected in the transmission confirmation BML document “top.bml”, the content corresponds to the content. The configuration may be such that BML content is executed.

  The digital broadcast receiver 4 executes an access BML document to access the BML server 3 and execute a transmission confirmation BML document (top.bml) in order to confirm the viewing of the data broadcast of each station.

  When the transmission confirmation BML document (top.bml) is executed, a screen as shown in FIG. 6A is displayed.

  When a station for which transmission of data broadcast is to be confirmed is selected from the displayed screens, “atv_list.bml” shown in FIG. 2 is executed, and a screen as shown in FIG. 6B is displayed. When the date / time on which the data broadcast is desired to be confirmed is selected, the BML content corresponding to the selected date / time is executed. Each selection item displayed on this screen corresponds to a folder in which the BML receiving apparatus 2 has uploaded BML content to the BML server 3, and in this embodiment, the selection items are uploaded separately for each broadcast reception date and time. Therefore, it can be selected for each broadcast reception date and time.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. In addition, the same number is attached | subjected about the structure similar to the said 1st Embodiment, and detailed description is abbreviate | omitted.

  In the above embodiment, the designation destination of the resource or the like in the BML document of the received BML content is rewritten. In this embodiment, each broadcast station, when broadcasting, the digital broadcast receiver 4 receives the description executed in normal data broadcast, that is, the content of the data broadcast held in its own storage area. A description sentence for broadcasting to be executed and a description sentence for network in which the digital broadcast receiver 4 accesses and executes the content of the data broadcast held by a device connected via the network via the network. Prepare and broadcast BML contents for data broadcasting.

  The description text for the network is such that, for example, a BML content including the BML document can be viewed via the network at a specified destination such as a transition destination or a reference destination described in the broadcast BML document. This is a descriptive sentence set in advance in the path of the BML server or the like in which the content of the data broadcast is held. This net description is sent to the contents of the data broadcast by the device having the conversion unit 202 of the first embodiment, with the designation destination such as the transition destination and reference destination described in the broadcast BML document. May be created by converting to a path such as a BML server that holds the URL.

  In addition, the BML document of the data broadcast content in the present embodiment determines whether to execute a broadcast description sentence or a net description sentence when executing the data broadcast content. There is a description to execute a description sentence according to the result. For example, there are the following methods.

  For example, “browser.getActiveDocument ();” is used to obtain a URI indicating the location where the currently executed BML document is stored, or “browser.getBrowserStatus ();” is used to obtain the current link state. Thus, it is a method of confirming from where the BML document currently being executed is the BML document acquired, and changing a description sentence to be executed according to the confirmation result. It should be noted that any method may be used as long as it is possible to determine whether a description statement for broadcasting should be executed or a description statement for network should be executed.

  Next, the operation in this embodiment will be described with reference to FIG.

  Each broadcasting station 1 prepares and broadcasts a BML document in which a description sentence for broadcasting and a description sentence for the network are described (step S201).

  The BML receiver 2 receives the data broadcasting TS broadcast from each broadcasting station (step S202). Then, the BML content is extracted from the TS, converted into a folder structure, and then uploaded to a predetermined area (folder) in the storage unit 203 of the BML server 3 via the network (step S203).

  The BML server 3 receives the BML document from the BML receiving device 2 by the receiving unit 201 and stores it in the designated area.

  Next, an operation for confirming the data broadcast stored in the BML server 3 will be described. It is assumed that the access BML content is already stored in the digital broadcast receiver 4.

  In order to confirm the data broadcast broadcast by each station, the digital broadcast receiver 4 executes the access BML document, accesses the BML server 3 and executes the transmission confirmation BML document (top.bml).

  When the confirmation BML document (top.bml) is executed, a screen as shown in FIG. 6A is displayed.

  When a station for which data broadcasting transmission is to be confirmed is selected, “atv_list.bml” shown in FIG. 2 is executed, and a screen as shown in FIG. 6B is displayed. When selected, the BML content corresponding to the selected date and time is executed (step S204).

  When the BML content is executed, it is determined whether to execute a description statement for the network or a description statement for broadcasting (step S205). If it is determined that the description statement for the network is to be executed, The description sentence is executed (step S206). If it is determined that the broadcast description is to be executed, the broadcast description is executed (step S207).

  In the above embodiment, a description sentence described in a description sentence for broadcasting and a description sentence for the net is prepared and broadcast in the same BML document, and the description sentence for the net is executed or broadcast. Has been described using a configuration that executes a description sentence according to the determination result. However, a broadcast BML document and a network BML document are prepared and broadcast, It may be configured to determine whether to execute the BML document or the broadcast BML document and execute the BML document according to the determination result.

  Also, in the above, a “browser.getActiveDocument ();” is used to obtain a URI indicating the location where the currently executed BML document is stored, or “browser.getBrowserStatus ();” is used to obtain the current The method to determine whether to execute the description statement for broadcasting or the description statement for the network by acquiring the link status was described, but there is the following method as a different method from this .

  For example, at the time of broadcasting, the contents of the binary table “30.btb” of the module name “0000” of the component “40” are broadcast as “0”, and the BML content broadcasted in the folder “200660413 — 110315” of the BML server 3 is stored. At this time, the conversion unit 202 converts the contents of the binary table to “1”. As a result, the content of the binary table “30.btb” of the module name “0000” of the component “40” of the folder “20060413 — 110315” illustrated in FIG. 2 becomes “1”. Then, the contents of this binary table are read into the BML document, and if the contents of the binary table are “1”, the description sentence for the net is executed, and if it is “0”, the description sentence for executing the description sentence for broadcasting is described. Let In this way, broadcast description statements are executed based on information (flags) indicating whether broadcast description statements written in a predetermined file should be executed or net description statements should be executed. It may be configured to determine whether to execute the description statement for the network. Although the description has been made using the binary table “30.btb” here, information indicating whether to execute a description sentence for broadcasting or a description sentence for the net in a predetermined file is provided. Any method can be used.

<Third Embodiment>
Next, a third embodiment of the present invention will be described. In the present embodiment, when the BML content of the data broadcast in a format that the terminal can view via the network is stored in the BML server 3 through the method described in the first and second embodiments, Next, a description will be given of a case where a transmission confirmation BML document is generated by describing a link for executing the BML content. In addition, the same number is attached | subjected about the structure similar to the said 1st Embodiment, and detailed description is abbreviate | omitted.

  As shown in FIG. 8, the BML server 3 includes a generation unit 204 in addition to the configuration of the above embodiment. The generation unit 204 detects when a new BML content is uploaded to the storage unit 203, and executes the new BML content based on a folder name (path name) in which the new BML content is stored. A link is generated, and a transmission confirmation BML document is generated or updated. In the present specification, atv_list. bml is generated or updated.

  The digital broadcast receiver 4 executes an access BML document for accessing the BML server 3 in order to view and confirm the data broadcast broadcast from each station. This BML document is for accessing the BML server 3 to execute the transmission confirmation BML document, and it may be stored in the digital broadcast receiver 4 in advance or received via a broadcast wave.

  The operation of this embodiment will be described. In the BML server 3 of this embodiment, various data of BML contents are stored in a hierarchy of broadcasting stations, broadcasting date / time, ES, modules, and resources.

  The BML receiving device 2 receives the data broadcast, extracts the BML content from the TS, and uploads it to the BML server 3. When uploading to the BML server 3, the BML receiving device 2 generates a folder with a folder name indicating the broadcast reception date and time on the lower level of the broadcasting station A, and uploads the folder to the generated folder.

  The generation unit 204 detects that a new folder has been generated, generates a link for executing the BML content stored in the folder, and generates or updates a transmission confirmation BML document.

  In the above description, the access BML document is used to access the BML server 3 to execute the transmission confirmation BML document. However, the present invention is not limited to this. For example, every time the transmission confirmation BML document is updated, the digital broadcast receiver 4 receives the updated transmission confirmation BML document via the broadcast wave, and the digital broadcast receiver 4 receives the transmission confirmation BML document. May be configured such that viewing of the BML content stored in the BML server 3 can be confirmed. In the above description, the access BML document and the transmission confirmation BML document are used. However, any data broadcast BML contents stored in the BML server 3 can be executed by accessing the BML server 3. The program is not limited to a BML document, but may be a program of another format.

<Example 1>
Examples of the present invention will be described.

  This example is an example corresponding to the first embodiment, and a case will be described in which the designation destination in the BML document is changed to a designation destination corresponding to the storage unit 203 of the BML server 3. In addition, the same structure as embodiment mentioned above is demonstrated using the same number, and detailed description is abbreviate | omitted. Also, the address of the BML server 3 is “192.168.1.137”, and the BML content uploaded by the BML receiving device 2 is stored in the “bml” folder of the storage unit 203. The folder structure of the unit 203 will be described with reference to FIG.

FIG. 9 is a part of a BML document for explaining an embodiment of the present invention.
Broadcast station A has a description sentence “browser.launchDocument (“ /40/0000/startup.bml ”,“ 40 ”and module name“ 0000 ”) and transitions to“ startup.bml ”with the module name“ 0000 ”. Assume that a BML document as shown in FIG. 9 (a) in which “cut”) is described is transmitted.

  In this case, in the BML server 3, a folder name “20060413 — 110315” indicating the broadcast reception date and time is generated below the broadcasting station “atv” of the “bml” folder in the storage unit 203, and the folder “40” of the folder “40” “Startup.bml” is stored in the folder of the module “0000” downstairs. Therefore, the “browser.launchDocument (“ /40/0000/startup.bml ”,“ cut ”)” of the broadcast BML document is broadcast down the broadcasting station “atv” of the “bml” folder in the storage unit 203. It must be rewritten to refer to “startup.bml” stored in the module “0000” in the down-level component “40” of the down-level component “4060413 — 110315”. Therefore, the conversion unit 202 must be set so as to convert to “BML server / root folder / broadcast station folder / broadcast date / time folder / component folder / module folder / startup.bml”. That is, as shown by 401 in FIG. launchDocument (“/40/0000/startup.bml”, “cut”) is added to browser. It is set so that it is converted to launchDocument (“http://192.168.1.137/bml/atv/20060413 — 110315/40/0000 / startup.bml”, “cut”). Alternatively, it is set to add http://192.168.1.1137/bml/atv/20060413 — 110315 before / 40.

  In the same module, for example, when the launchDocument link destination is another module in the same ES, that is, for example, startup of module “0001”. bml to module "0000" startup. When transitioning to bml, as shown in 402 of FIG. launchDocument (“/40/0000/startup.bml”, “cut”) is replaced with browser. Set to convert to launchDocument (“./0000/startup.bml”, “cut”).

  When the BML receiving apparatus receives a data broadcasting TS actually broadcast from the broadcasting station 1 (broadcasting station A), the BML content is extracted from the TS, converted into a folder structure, and the storage unit 203 of the BML server 3 via the network. The broadcast date and time “20060413 — 110315” is generated in a predetermined folder in the folder, that is, “atv” below the folder “bml”, and uploaded to the folder below.

  The conversion unit 202 searches for a preset correction location from the BML document in the uploaded BML content. In this embodiment, browser. Search for launchDocument (“/40/0000/startup.bml”, “cut”).

  The conversion unit 202 is a browser. When launchDocument (“/40/0000/startup.bml”, “cut”) is retrieved, browser.com as shown in FIG. launchDocument (“http://192.168.1.137/bml/atv/20066043 — 110315/40/0000 / startup.bml”, “cut”), or browser. A BML document in which launchDocument (“../0000/startup.bml”, “cut”) is described.

  By storing the BML document generated in this manner in the BML server 3, a data broadcast broadcast in an area where the digital broadcast receiver 4 executing the BML document cannot be received via the network can be viewed. It is possible to confirm the data broadcasting, and it is possible to centrally manage the data broadcasting transmission confirmation.

<Example 2>
This example is an example corresponding to the first embodiment, and a case will be described in which a descriptive sentence including a module designation destination in a BML document is not executed.

  As shown in FIG. 9A, the broadcasting station A makes a transition to “startup.bml” having a component name (component tag value) “40” and a module name “0000”, “browser.launchDocument (“ /40/0000/startup.bml","cut ")" is transmitted.

  In this BML document, browser. If it is not necessary to execute launchDocument (“/ 40/0000 / startup.bml”, “cut”), in order to add “//” to the front of the description sentence and comment out, As shown, browser. launchDocument (“/ 40/0000 / startup.bml”, “cut”) // browser. It is set to convert to launchDocument (“/40/0000/startup.bml”, “cut”). Alternatively, as shown in 404 and 405 in FIG. "//" is added in front of launchDocument ("/40/0000/startup.bml", "cut"), or browser. The launchDocument (“/40/0000/startup.bml”, “cut”) is set to be deleted.

  When the BML receiving apparatus receives a data broadcasting TS actually broadcast from the broadcasting station 1 (broadcasting station A), the BML content is extracted from the TS, converted into a folder structure, and the storage unit 203 of the BML server 3 via the network. The broadcast date and time “20060413 — 110315” is generated in a predetermined folder in the folder, that is, “atv” below the folder “bml”, and uploaded to the folder below.

  The conversion unit 202 searches for a preset correction location from the BML document in the uploaded BML content. In this embodiment, browser. Search for launchDocument (“/40/0000/startup.bml”, “cut”).

  The conversion unit 202 is a browser. When launchDocument (“/40/0000/startup.bml”, “cut”) is retrieved, // browser. BML document in which launchDocument (“/40/0000/startup.bml”, “cut”) is described, or browser. LaunchDocument (“/40/0000/startup.bml”, “cut”) is a deleted BML document.

  The BML document generated in this way is stored in the BML server 3 so that the digital broadcast receiver 4 executing the BML document can watch the data broadcast broadcast in an area that cannot be received via the network. Viewing can be confirmed only at the place to be confirmed, and unified management of data broadcasting transmission confirmation becomes possible.

<Example 3>
This example is an example corresponding to the first embodiment, and a case will be described in which the designated destination in the BML document is a specific storage area in the digital broadcast receiver.

  For example, in general data broadcasting, the user causes the digital broadcast receiver 4 to set the postal code of the user's own residence so that weather forecasts, local news, etc. are displayed immediately. In this case, for example, as shown in FIG. 10 (a), “zip = browser.readPersistentArray (“ nvram: // receiverinfo / zipcode ”,“ S: 7B ”);” is described in the BML document and the nverm receiverinfo is written. The zip code configured at the lower level is accessed to obtain the zip code by referring to the zip code, and information corresponding to the zip code is provided. However, since access restrictions are applied to each area of nvram, when a BML document stored in the BML server 3 without access permission is accessed, the execution of the BML document is stopped. Therefore, in the BML content stored in the BML server, zip = browser. If readpersistentarray (“nvram: // receiverinfo / zipcode”, “S: 7B”); is executed, the BML document stored in the BML server 3 is allowed to access the zipcode that is configured under the receiverinfo of nvram. Because it is not done, it becomes impossible to watch.

  Therefore, “zip = browser.readPersistentArray (“ nvram: // receiverinfo / zipcode ”,“ S: 7B ”);”, “zip = browser.readPersistentArray (“ nvram: // local_web / 3 "," S: 7B ");" or receiveinfo / zipcode is set to local_web / 3, and the local_web downstairs of the nvram of the digital broadcast receiver 4 that is the area where access is permitted The storage area “3” configured in FIG. 4 is specified so that the execution of the BML document is not interrupted. In this case, the postal code that is the target information is written in advance in local_web / 3 of nvram.

  When the BML receiver 2 receives the data broadcasting TS actually broadcast from the broadcasting station 1 (broadcasting station A), the BML content is extracted from the TS, converted into a folder structure, and the storage unit of the BML server 3 via the network. It uploads to a predetermined folder in 203, that is, “atv” downstairs of the folder “bml”.

  The conversion unit 202 searches for a correction location from the BML document in the uploaded BML content. In this embodiment, zip = browser. readPersistentArray (“nvram: // receiverinfo / zipcode”, “S: 7B”);

  zip = browser. readPersistentArray (“nvram: // receiverinfo / zipcode”, “S: 7B”); is retrieved, this portion is shown as zip = browser. It is converted into a BML document such that readPersistentArray (“nvram: // local_web / 3”, “S: 7B”);

  In the above-described embodiment, the configuration for changing the reference destination of the postal code has been described. However, a configuration in which a dummy postal code is set to be written in the BML document may be used.

  Next, a method different from the above in the case where the reference destination of the module in the BML document is changed will be described. Note that the digital broadcast receiver 4 of the present embodiment can receive BML content of data broadcasts broadcast by a broadcast station in the same network as the broadcast station that broadcasts the BML content to be confirmed for viewing via broadcast waves. It shall be possible.

  When a module lock is performed in data broadcasting, <beitem id = “pointLock” type = “ModuleLocked” onoccur = “pointMODLock ();” subscribe = “subscribe / mod” / 60 / ref_60 ” The lock is made with reference to the module “0006” of the component “60” in the broadcast BML content. In this case, the digital broadcast receiver 4 refers to, for example, “arib-dc: //−1.-1.−1/60/0006” and locks the module stored therein. Also good.

  Therefore, as shown by reference numeral 407 in FIG. 4, the conversion unit 202 sends <beitem id = “pointLock” type = “ModuleLocked” onoccur = “pointMODLock ();” subscribe = “subscribe” module / required_module / 0006 ” <Beitem id = “pointLock” type = “ModuleLocked” onoccur = “pointMODLock ();” subscribe = “subscribe” module_ref = “arib-dc: //−1.0006/−1. > To be set.

  Then, as described above, a search is made as to whether or not the corrected portion is present in the BML document, and actually <beitem id = “pointLock” type = “ModuleLocked” onoccur = “pointMODLock ();” subscribe = “subscribe =” subscribe = When “/ 60/0006” /> is searched, <beitem id = “pointLock” type = “ModuleLocked” onoccur = “pointMODLock ();” subscribe = “subscribe” module_ref−crid−1 .-1.1-1 / 60/0006 "/> to convert the BML document.

  By executing the BML document converted in this way, it is possible to view a data broadcast broadcast in an area where the digital broadcast receiver executing the BML document cannot receive, and to confirm the transmission of the data broadcast. Centralized management is possible.

<Example 4>
This example is an example corresponding to the first embodiment, and will be described for conversion of a BML document when nvram is a designated destination as a data storage destination in the BML document.

  As described above, normally, access is restricted to nvram, and when access is not permitted, the BML content is canceled and cannot be viewed.

  Therefore, “//” is added to the descriptive sentence in which nvram is specified as a comment out. Alternatively, it is set to delete the description.

  In this case, as described in the third embodiment, the digital broadcast receiver 4 may be set so as to designate a location that can be accessed and stored.

  Then, the same processing as that in the second or third embodiment is performed to convert the BML document.

  By executing the BML document changed in this way, it is possible to view a data broadcast broadcast in an area where the receiver that is executing the BML document cannot receive, and centralized management of data broadcast transmission confirmation Is possible.

<Example 5>
This example is an example corresponding to the second embodiment, and the same components as those in the above embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

  In this embodiment, a description will be given using “browser.getActiveDocument ();” as a method for determining whether to execute a description statement for a network or a description statement for broadcasting in a BML document. The determination may be made using “browser.getBrowserStatus ();”.

  “Browser.getActiveDocument ();” is for acquiring the URI of the BML document currently being executed. Of the values acquired using “browser.getActiveDocument ();”, If the part contains an address indicating a folder in the storage unit 203 of the BML server 3 in which BML content is stored, “bml” in this specification, it is determined that the part is a net, and other than “bml” This is a method of determining that the broadcast is broadcast and executing a descriptive sentence according to the determination.

As shown at 1101 in FIG. 11, the URI of the BML document currently being executed is acquired by “browser.getActiveDocument ();”, and the acquired URI is put into a variable bmlserver_ActiveDocument. Then, as indicated by reference numeral 1102 in FIG. 11, a necessary part of this value is further input to the variable bmlserver_ActiveDocument_root.

If bmlserver_ActiveDocument_root is “bml” (1103 in FIG. 11), it is determined to be a net, and zip = browser. readPersistentArray ("nvram: // local_web / 3", "S: 7B"); (1104 in FIG. 11) and refer to "nvram: // local_web / 3", "S: 7B" get. If bmlserver_ActiveDocument_root is other than “bml” (1105 in FIG. 11), it is determined that the broadcast is made, and zip = browser. readPersistentArray ("nvram: // receiverinfo / zipcode", "S: 7B"); is performed (1106 in FIG. 11), and a zip code is obtained with reference to "nvram: // receiverinfo / zipcode".

  In this way, it is determined whether to execute the description statement for the net in the BML document or the description statement for broadcasting according to the contents of the URI of the currently executed BML document, and the result of the determination By executing the descriptive text corresponding to the data broadcast, it is possible to view the data broadcast broadcast in the area that cannot be received by the receiver executing the BML document, and the transmission broadcast transmission confirmation can be centrally managed. . Note that the conversion processes described in the first to fifth embodiments may be combined in a timely manner.

  Each device of the present invention described above can be configured by hardware as is apparent from the above description, but can also be realized by a computer program. In this case, functions and operations similar to those of the above-described embodiment are realized by a processor that operates according to a program stored in the program memory of each device.

  The present invention can also be applied to a case where data broadcasting is provided when digital broadcasting is transmitted using an IP network in an IPTV or the like.
