The data program production device 102 of the local broadcasting station includes an authoring unit 131, a template storage unit 132, a material data net distribution information storage unit 133, a material data net distribution unit 134, a combining unit 135, and a conversion sending unit 136. And The material data network delivery unit 134 is connected to an external second data providing device 141, and the conversion sending unit 136 is connected to an external multiplexing device 142. The data broadcast program production device 101 of the key broadcast station produces, for example, a data broadcast program “weather information” as shown in FIG.

This "weather information" 201 is composed of two data broadcast program elements, "national weather" 202 and "Kanto weather" 203. The viewer can switch between “national weather” 202 and “Kanto weather” 203 by operating the remote control.

Figure 3 shows an overview of the production of this data broadcast program “Weather Information” 201. The program template 300 produced using the authoring unit 111 and the material data 303 acquired from the first data providing device 121 through the material data distribution unit 114, 303 24 and 305 are synthesized by the synthesizing section 115 to form a data broadcast program 201.

The authoring unit 1 1 1 produces a program template 3 0 1 by an input operation of a program creator. The program template 301 is produced for each data broadcast program element.

The template storage unit 112 stores the program template 301. Here, the program template 301 is prepared in advance only information that does not need to be changed with time, such as a screen layout and character strings and images that are always displayed on the screen. Information that changes over time, such as actual weather data (such as “sore” and “candy”) and images of weather charts, is acquired from outside as material data, and the combining unit 115 combines the two. To produce a data broadcast program element.

The program template 301 shown in FIG. 3 is composed of the ARIB standard resources 401, 402, 400.404, the synthesis instruction information 405, and the BML replacement list 4 shown in FIG. 06, 407.

Each of the resources 401 to 404 is identified by a resource name 408, has a document / image type 409, and includes the data described in the content column 410.

The combining instruction information 405 is identified by the combining instruction information name, and details of its contents are shown in FIG. Compositing instruction information “GOUSEI.TXT” 405 consists of text, with two items on each line, separated by commas 501. The first item 502 before the comma is the resource name of the resource that constitutes the data broadcast program element generated by the combining process, and the second item 503 is the resource name described in the first item. — The name of the material data used to generate the source.

Details of the contents of the BML replacement lists 406 and 407 are shown in FIG. The BML replacement list 406 is shown in the content 601 of ZENKOKU. RLS, and the BML replacement list 407 is shown in the content 602 of CHIOU.

FIG. 7 is a diagram showing a part of the details of “ΓΖΕΝΚΟΚυ. BML” of the resource 401.

The material data net distribution information storage unit 113 stores net distribution setting information and an IP address correspondence table.

FIG. 8 shows an example of the net distribution setting information stored in the material data net distribution information storage unit 113 and an IP address correspondence table.

The net distribution setting information 801 is information created in advance by a program creator and defines the operation of the material data net distribution unit 114. The network distribution setting information 801 includes a data providing device column 802, a material data name column 803, and a distribution destination column 704. According to the network distribution setting information 801, the material data network distribution unit 114 receives the material data specified by the material data name from the data providing device described in each line of the network distribution setting information 801. The data is notified to the synthesizing unit 115 and distributed to the distribution destination.

In the data distribution device 802 column and the material data name 803 column of the net distribution installation information 801, a simple character string can be described, and a general wildcard can be described. The algorithm for determining the matching between a wildcard and a character string is widely known, and therefore will not be described. For example, by specifying “weather information providing device” as the data providing device and specifying “ne.ne” as the material data name, the specification that all the material data provided by the weather information providing device will be delivered to the distribution destination Can be easily described.

The IP address correspondence table 805 describes the correspondence between the name 806 of the source or destination of the material data and the IP address 807. Here, it is assumed that the distribution of the material data is performed using TCPZIP, and the distribution destination of the material data is specified and the provider of the arrived material data is determined.

In the data broadcasting program production apparatus 101, the first data providing apparatus 121 is identified by the name "weather information providing apparatus" and communicates with the first data providing apparatus 121. The IP address used at this time is “1 3 3. 1 8 8. 5. 1 1 2”. The IP address correspondence table 805 has a plurality of IP address columns 808. For example, it is also possible to describe a plurality of IP addresses in a local broadcast station data broadcast program production device and distribute one material data to a plurality of broadcast stations.

The first data providing device 122 transmits the material data to the material data network distribution unit of the data broadcasting program production device 101 of the key broadcasting station. Here, the material data refers to data that changes with time to be combined with the program template 301 and becomes a data broadcast program element. The material data 303, 304, and 305 shown in FIG. 3 is transmitted, for example. The material data 303 is a weather chart, and is transmitted as a J PEG image as shown in FIG. 9A. The material data 304 and 305 are transmitted as text data as shown in FIGS. 9B and 9C, respectively. Each piece of material data 901, 902, 903 has a material data name.

Upon receiving the material data from the first data providing device 12 1, the material data network distributing section 1 14 stores the source data providing device and the material data name in the material data network distributing information storage section 1 1 3 It is determined whether or not it is described in the net distribution setting information 8001, which is stored in the. If not described, the synthesizing unit 1 15 is notified of the material data. If it is described, it notifies the combining unit 115 and distributes the material data to the destination. At this time, distribution is performed to the corresponding IP address of the distribution destination with reference to the IP address correspondence table 805 stored in the material data net distribution information storage unit 113.

For example, the material data 900 of the weather map has the material data name “zenkoku—tenkizu.jpg” described in the second line of the net distribution setting information 80.1. It is distributed to the IP address of the production device 102, "13.4.100.0.16.11". Similarly, since the material data 902 has the material data name “zenkok u_d ata. Xm 1” described in the first line of the net distribution setting information 801, the data broadcast of the local broadcasting station of the distribution destination is It is distributed to the program production device 102.

The material data 903 is notified only to the synthesizing unit 115 because the material data name “chiho_data.xm1” is not described in the net distribution setting information 8001. Upon receiving the notification of the material data from the material data network distribution unit 114, the combining unit 115 refers to the program template combining instruction information 405 stored in the template storage unit 112. It is determined whether or not all the material data described in the second item 503 of the combining instruction information 405 has been notified, and when all of them have been notified, the combining of the program template and the material data is started.

FIG. 10 is an explanatory diagram schematically showing the synthesis of the data broadcast program by the synthesis unit 115. This corresponds to FIG. 3 shown above.

The combining unit 115 refers to the combining instruction information 405 (see FIG. 5), and generates the resources specified in the first item 502 of each row in the following procedure.

(1) If the second item 503 is blank, the resource with the same name in the program template is copied and used as the resource of the data broadcast program element. For example, "ZENKOKU-LOGO. J PG" 1001 and "CH I HOU-LOGO. J PG" 1002.

(2) If the second item 503 is not blank and the resource type specified in the first item 502 is other than BML, copy the resource with the same name in the material data and copy it.

—This is the resource of the broadcast program element. For example, "ZENKOKU_TENK I ZU. J PG".

(3) If the second item 503 is not blank and the type of the resource specified in the first item 502 is BML, the resource specified in the second item 503 for the resource of the same name in the program template 301 The process of synthesizing the BML embedded data in the data (hereinafter referred to as “BML synthesis process”) is used as the resource of the data broadcast program element.

Here, the BML synthesis processing will be described in detail. Program template resources (type is BML) For example, combine the BML embedded data in resource リソース. BML ”401 (see Fig. 7) and material data — evening“ ZENKOKU—DATA. XML ”902 (see Fig. 9B). In this case, the BML replacement list “ZENKOKU. RLS” 601 of the program template corresponding to the resource is used.

That is, the content of the id attribute “tenki 01” of “ZENKOKU. BML” 401 matches the key “hokkaido” of the id attribute “te nk i 01” of e 1 ement of “ZENKOKU. RLS” 601. ZE NKOKU— D AT A. XML ”902 key“ hokka ido ”and“ va lue ”“ replace ”. This process is executed for all e 1 elements of “Z ENKOKU. RLS” 601.

As a result, as shown in FIG. 10, a resource 1003 is obtained in which a part of “OKU. BMLJ 401” in the program template 301 has been replaced with embedded data “ZENKOKU—DATA. XML” 902. The resource 1003, the resource 1001, and the resource 901 constitute a data broadcast program element 1004 (202).

Similarly, “CH I HOU. BMLJ 1005” in the program template 301 uses “CH I HOU. RSL” 602 as the resource “CH I HOU. BMLJ 1

It becomes 006. Resource 1006 and resource 1002 are data broadcast program elements

Construct 1007 (203).

The synthesizing unit 115, when synthesizing the data broadcast program 1008 composed of the data broadcast program element 1004 and the data broadcast program element 1007, notifies the conversion / transmission unit 116.

The conversion transmission section 116 converts the data broadcast program elements 1004 and 1007 into an MPEG2 transport stream in a predetermined format, and repeatedly transmits them to the multiplexer 122.

The multiplexing device 122 multiplexes the transport stream of the data broadcast program elements 1004 and 1007 transmitted from the conversion transmission section 116 and the transport stream of video, audio, and the like, and transmits the multiplexed signal.

Next, the data broadcasting program production device 102 of the local broadcasting station will be described.

The converted data broadcast program is notified to the conversion sending unit 136.

Conversion transmitting section 136 converts and transmits the data broadcast program to multiplexer 142 (S1 712), and the process ends.

Next, the details of S1604 in the flowchart of FIG. 16 will be described with reference to the flowchart of FIG.

The material data net distribution unit 114 reads one line of the net distribution setting information 801 stored in the material data net distribution information storage unit 113 (S1802). arrival It is determined whether or not the data providing device name of the distribution source of the material data matches the read data providing device. That is, a name 806 corresponding to the IP address 807 of the IP address correspondence table 805 is read from the IP address of the distribution source, and it is determined whether the name matches the data provision device 802 of the network distribution setting information 801 (S1). 804).

If there is a match, it is determined whether or not the material data name given to the arrived material data matches the material data name of the net distribution setting information 801 (S1806). If they match, it is determined that the material data should be delivered to the delivery destination of the network delivery setting information 801 (S1808).

If it is determined in S1804 and S1806 that there is no match, it is determined that the material data is to be notified only to the synthesizing unit 115 (S1810).

Next, the material data net distribution unit 114 determines whether there is a line that has not been read yet in the net distribution setting information 801 (S1812), and if so, returns to S1802, otherwise ends the process. I do.

Next, details of S1612 in the flowchart of FIG. 16 will be described using the flowchart of FIG.

The synthesizing unit 115 reads one line of the content of “GOUSE I. TXT” of the synthesis instruction information 405 of the program template stored in the template storage unit 112 (S1902). It is determined whether or not the second item 503 is blank (S190.4). If it is blank, the resource having the same name as the resource name specified in the first item 52 is copied from the program template (S1906), and the process proceeds to S1914.

If it is not blank, the synthesizing unit 115 determines whether the resource type of the first item is BML (document) (S1908). If it is not BML, the same name as the resource specified in the second item 502 Is copied from the material data (S1910), and the process moves to S1914.

When the resource type of the first item is BML, the program template is searched for a resource with the same name as the resource name specified in the first item, and the BML embedded data with the name specified in the second item is used as the source. The data is searched from the data, and both are synthesized by BML synthesis processing using the BML replacement lists 406 and 407 (S 1912), and the process proceeds to S 1914. The synthesizing unit 115 determines whether or not there is a line that has not been read yet in the synthesis instruction information 405 (S 191 4). If not, the process ends.

In the present embodiment, the network distribution setting information is stored in advance in the material data network distribution information storage unit 113 of the data broadcasting program production apparatus 101 of the key broadcasting station. Data broadcast program production device 102 Data distribution program storage device in which the network distribution setting information is also stored in advance in the network distribution information storage section 133 so that the key broadcast station and the local broadcast station can communicate with each other. It goes without saying that material data can be distributed between 101 and 102.

Also, in the present embodiment, although the data broadcast program production device 102 of the local broadcast station independently produced the data broadcast program element, it is assumed that the data broadcast program element is the same as the data broadcast program element of the key broadcast station. Is also good. In this case, without receiving the material data from the second data providing device 141, all of the material data can be received from the data broadcasting program production device 101 of the key broadcasting station.
