Included in the data.
[0077]
Note that the search result in the metadata search server 12 is not limited to one, and a plurality of search results may be output. In this case, all the metadata is output to the client terminal 11 or the metadata is output. Priority can be set based on the data size or the registration date of metadata, and output can be performed based on the priority. The setting of the priority order may be added to a script generated by the client terminal 11 or may be registered in the metadata search server 12 so as to perform processing for the setting condition. Further, the content of the extracted metadata is not limited to this, and can be set according to the content of the metadata set in advance in the metadata search server 12 or in response to a request from the client terminal 11.
[0078]
Next, an example of a description of a program production module produced by the automatic production server in an effect request will be described with reference to the drawings.
[0079]
FIG. 6 is a diagram showing an example of the effect request and the description in the present invention. Here, FIG. 6 (a) shows the production request of FIG. 4 (b) {2}, and FIG. 6 (b) is registered in the automatic production server 14 by the program production module server 15 and based on the production request. The extracted description is shown.
[0080]
When the client terminal 11 outputs the production request to the automatic production server 14 as a step of S09, the automatic production server 14 selects a description that meets the production request from the description obtained from the program production module server 15, and sends the description to the client terminal 11.

(2)) and the like. The content of the above-mentioned description is not limited to this, and may be any content that can be produced using the program production module group.
[0081]
In response to the input production request, the automatic production server 14 adds, for example, bright music for bright topic news, or adds production data that makes the announcer's expression smile to the description. If it is a dark topic, it is possible to add dark music and production data that makes the expression of the announcer sad.
[0082]
In order to perform the process of adding the effect data to the description as described above, the automatic production server 14 is provided with effect information adding means, and the effect information adding means analyzes tag information included in the description or analyzes character information. By doing so, the contents are grasped, and the above-described effect data based on the contents is added to the description. Thereby, for example, it is possible to change the tune of the BGM or the narrative of the announcer according to the genre and content of the material using the data of MPEG7, thereby enriching the program content and providing a program with high added value. be able to.
[0083]
As described above, by providing the automatic production server 14 for the production conditions conventionally set manually and inputting the production conditions to the automatic production server 14, the information necessary for producing the program can be easily obtained. Can be.
