Description

A system for creating and operating real-time data content for data broadcasting and its control method {A SYSTEM FOR CREATING AND OPERATING REAL-TIME DATA CONTENTS FOR DATA BROADCASTING AND A CONTROLLING METHOD THEREOF}

The present invention relates to a system for generating contents including real time data for data broadcasting and real time information corresponding thereto, and a system for transmitting the generated real time information. More specifically, the user can easily designate real-time information to produce real-time data broadcasting content, and relates to a production and operation system of real-time data content in which data is automatically or manually updated in real time through a real-time operating system.

In general, the real-time data content for data broadcasting refers to a part or all of data included in the content over time, such as weather, traffic information, and sports competition information, in the data broadcasting. Refers to updated data broadcasting content.

In order to produce content including real-time data in data broadcasting, programmers and designers produce content for data broadcasting using a content broadcasting tool for data broadcasting or using a programming language conforming to a standard. At this time, it is impossible to update and transmit data manually and in real time during the life of the content. Therefore, in the case of content including real-time data information, a real-time operating system that can easily produce real-time data and automatically updated is essential. That is, an authoring tool that can generate data broadcasting content including real-time data and establish a relationship with the real-time data, and an operating system that can automatically update whenever the raw database used in the real-time data content changes. Required.

Here, the raw database refers to data expressed in extensible markup language (XML) format called "extensible notation language" including DBMS (common database management system) called general "database management system", and other general methods. Contains data for all real-time data content, expressed as.

By the way, in the field of contents production technology for conventional data broadcasting, there is an inconvenience to make a real time application for producing data broadcasting content including real time data and a real time operating system corresponding thereto whenever necessary through programming.

In addition, there was no authoring tool that allows the user to freely specify the structure of the real-time data or edit the design, and modification and recycling were impossible. Therefore, in order to produce data broadcasting contents including real-time data, a lot of time and manpower were required to create a real-time application, an operating system for operating real-time data, and an interface for transmitting updated real-time information to a transmission system. There is a problem that it is difficult to efficiently produce data broadcasting contents including real time data.

In addition, since programming to process real-time data in the data broadcasting content has to be programmed, it is difficult to produce data broadcasting contents including real-time data information unless an expert.

In addition, in order to transmit the content including the real-time data from the data broadcasting content to be updated and updated in real time, programming to process this is required, but there is a problem in real-time data processing because there is no system for managing and processing the real-time data integrally.

The present invention has been made under the technical background as described above, and an object of the present invention is to provide a system for producing and operating real-time data contents for data broadcasting and a method of controlling the same for easily producing and operating real-time data information in the production of contents for data broadcasting. do.

In addition, it is another object to make it easy for a user to produce any kind of real-time data broadcasting content by using the real-time data in a data broadcasting content production tool.

In addition, another object of the present invention is to allow a user to set graphic design elements in producing data broadcasting contents.

In addition, the real-time data broadcasting operating system is not created for each application, but the real-time operating system proposed by the present invention analyzes the structure of the necessary real-time data defined by the metadata as well as the production of the content in the real-time broadcasting authoring tool. The objective is to develop an operating system that automatically collects, edits, and generates real-time information for various real-time applications that have already been created.

In addition, it is another object to collect raw real-time information to be processed and generated into a form of data that can be interpreted in a real-time application automatically generated by the authoring tool.

The objects, technical configurations, and effects thereof of the present invention described above will become more apparent from the following description of the embodiments.

DETAILED DESCRIPTION Embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

Now, a liquid crystal display and an irradiation apparatus for a liquid crystal display according to an embodiment of the present invention will be described in detail with reference to the drawings.

Figure 1 shows the overall structure of the system for producing and operating real-time data content for data broadcasting according to the present invention.

As shown in FIG. 1, the system according to the present invention is largely composed of an authoring tool 10, a real-time information management system 20, and a transmission system 30. The transmission system 30 transmits a broadcast signal to the set-top box 40 on the receiving side via a communication channel via wireless or satellite. The transmission system 30 may be replaced with a verification system for testing whether transmission of a broadcast signal is performed correctly.

The authoring tool 10 includes a real-time information definer 11, an editor 12, a real-time information designator 13, a code generator 14, a file input / output unit 15, and an interface 16. In the authoring tool 10, the real time information definer 11 forms a structure of real time information, and the editor 12 designs an application for data broadcasting. The real-time information designator 13 assigns the structure of the real-time information to the application, and the code generator 14 generates a code of the application to generate real-time data content for data broadcasting. The file input / output unit 15 and the interface 16 transfer the structure and application of the generated real-time information to the real-time information management system 20 and the transmission system 30.

The authoring tool 10 includes a function for defining a structure of real-time information. In other words, the real-time information is expressed in the form of metadata that can be expressed in real-time information of various fields. The definition of the real-time information is considered to be able to represent various types of information, in the present invention, the structure of the real-time information is expressed in XML format.

For example, if the player information in the football game should be able to process the information on the replacement player during the live broadcast, the structure of the real-time information for the football player is expressed as follows.

Ex) Football player real time information

<Player> Player <PhotoPath> PhotoPath </ PhotoPath>

<Position> Position </ Position>

<Body size> body size </ body size>

<Own> belonging </ belonging>

<Main career> major career </ main career>

<Special Features> Special Features </ Special Features>

</ Player>

If it's weather forecast

<Weather> Weather

<Temperature> temperature </ temperature>

<Humidity> Humidity </ Humidity>

<Wind direction> wind direction </ wind direction>

</ Weather>

The same form can be used.

The key point of the present invention is that after defining the real-time information, the rest of the work is to parse the formal information expression in the authoring tool 10 and the real-time information management system 20 to automatically express and process it. That is, when the information defined and specified in the same manner is transferred from the authoring tool 10 to the real-time information operating system 20 by being included in the document file for the authoring tool, the real-time information operating system 20 is the authoring tool 10. Analyze the structure of real-time information specified in the system, and collect, edit, save, preview, or simulate the real-time information according to the structure. Therefore, it is not necessary to produce a separate real-time information management system according to the genre or the characteristics of the real-time application.

The real time information operating system 20 includes a first interface 21, a real time information editor 22, a real time information previewer 23, a file input / output unit 24, a code generator 25, a real time data generator 26. And a second interface 27, which is connected to access the external DB 210 and the internal real-time DB 220. The first interface 21 accesses an external DB 210 provided by an external contents provider (CP). The real-time information editor 22 reads the structure of the real-time information generated by the authoring tool 10 through the file input / output unit 24 to analyze the configuration of the real-time information required, and based on the analyzed result The content provided by the external DB 210 and the real-time information are read from the internal real-time DB 220 and edited. During the editing process, updating of the real time information may be performed automatically or manually. The code generator 25 and the real-time data generator 26 convert the result obtained in the real-time information editor 22 into codes and generate real-time data, respectively. The second interface is the authoring tool 10 and the transmission system. It is for communication with (30). The real-time information previewer 23 is for testing the real-time data applied to the application in advance.

The delivery system 30 includes an interface 31 and a delivery module 32 therein. The interface 31 is for communication between the authoring tool 10 and the real time information operating system, and the transmission module 32 transmits real time data, real time application, audio and video signals in the form of broadcast signals.

Next, the overall operation of the system according to the present invention will be described with reference to FIG.

2 is a flowchart illustrating the operation of the system for producing and operating real-time data contents for data broadcasting according to the present invention.

When the operation is started (S1), the data structure of the real-time data used in the system is determined (S22). The data structure is a form of standardized metadata, and is represented in the form of a document type definition document (DTD: hereinafter referred to as DTD) written in XML. DTD is completed based on the data structure determined in step S22 (S24). Based on the DTD, the authoring tool 10 designs and edits content corresponding to the DTD (S231). Then, a link operation for establishing a relationship between the DTD and real-time data is performed (S232). Meanwhile, a raw database consisting of data constituting the content using the DTD is constructed (S25), and XML data is extracted from the DTD and the raw database (S261). Next, XML for transmission is configured with the extracted XML data (S262). On the other hand, when the link operation for the DTD and the real-time data is completed in step S232, an AAT file in which the content and the real-time data are integrated is generated (S233). The AAT means a file format arbitrarily defined by the applicant, Aircode. Next, a code is generated using the AAT file (S263), and a real time application is executed (S27). Finally, the code and real-time data are generated by the execution of the application, and the transmission XML and the generated code and the real-time data obtained in step S263 are sent to the set-top box 40 by the delivery system 30. In step S28, the entire operation is completed (S29).

3 illustrates a link operation between the DTD and real-time data performed in step S232.

As illustrated in FIG. 3, the object defined in the editing screen, the external data, and the external data DTD are combined with each other and represented as a tree structure DTD layout. In other words, the defined real-time information structure is displayed on the edit screen in the form of a tree so that the user can easily recognize it during the editing process in the authoring tool. It can be seen that it provides a user interface that can show whether it should be in the form of a graphical user interface (GUI).

When real-time data broadcasting service is required, information transmission format between data to be transmitted in real time and real-time application that is already transmitted and executed must be defined. When implementing a real-time service in a conventional manner, a real-time application and an operating system corresponding thereto have been implemented, and the data format has been defined and used by the programmer every time. In the present invention, the data transmission format between the real time application and the real time information operating system 20 is automatically determined according to the real time information structure defined by the authoring tool 10. Therefore, it has the advantage of delivering real time information to various kinds of real time applications using one real time information operation system.

Real-time source data can be divided into the case of importing from the internal DB and the case of using the source provided from the external CP when the user inputs in real time. In the present invention, the manual input, editing function and internal DB utilization method provide an editing method and use XML in the internal DB.

In addition, the interface with the transmission system is modularized so that real-time and updated information generated by interfacing with various types of transmission systems can be delivered by the same protocol. This method has the advantage that the real-time update can be confirmed through the verification system before the actual delivery service by transmitting information through the same interface as the transmission system or the verification system.

4 illustrates an internal structure of the real-time information operating system shown in FIG. 1 in more detail.

That is, FIG. 4 illustrates the operation of the real-time information management system 20. The real-time information management system 20 is a DTD defined, the AAT file for content generation edited based on the DTD in the authoring tool 10, the source database code generator 25, XML processor 261, real-time information editor (22) and manages using a module such as a real-time information previewer 23, and sends the request to the delivery system 30 using the second interface 27. The user interface 211 receives and processes an update / edit command from an operator. In the real-time information management system 20, source code / data and a request for transmission / retransmission are transmitted to the transmission system 30.

Next, Fig. 5 shows the structure of the AAT file used in the present invention. The AAT file of FIG. 5 is for transferring information between the authoring tool 10 and the transmission system 30 or the verification system. That is, FIG. 5 illustrates the contents of an AAT file including all configuration information for automated content production and real-time service. All of this information includes all the information necessary for real-time data broadcasting, including basic enhanced content, and all the information necessary for content management, including operational automation and convenience, and content access rights. Using it, authoring tools, delivery systems or verification systems automate a series of operational flows.

6 shows an interface between the authoring tool and the delivery system shown in FIG.

That is, the authoring tool 10 shows information for initially delivering content directly to the delivery system 30 without passing through the real-time information management system 20. In FIG. 6, an application represents a source file generated by an authoring tool, and a resource is various images or other resource information required by the application. Initial data (Data) is data information necessary for the initial time when the application is updated in real time.

FIG. 7 illustrates an interface between the real time information operating system and the transmitting system shown in FIG. 1.

FIG. 7 illustrates information transmitted from the real-time information management system 20 to the transmission system 30 in a real packet upon update. That is, the data is divided into two types, a data carrousel method and an addressable section method, and there is a slight difference in the information transmitted according to each method.

8 illustrates an interface between the external DB 210 and the real-time information management system 20 shown in FIG. When the application is loaded from the database, it is divided into application info (application info), which is the information of the application, and "application", which is actual data. The application information is divided into genres, names, descriptions, and the like, and the "Application" is divided into an application, a resource, and initial data. This "Application" is compressed and stored when stored in the database.

As described above, the real-time data content production and operation system for data broadcasting of the present invention can easily and quickly create a real-time application for data broadcasting using a graphical user interface, and can manage real-time information through a real-time operating system. Can be. In addition, by realizing the real-time information can be represented by a single real-time operating system without having to separately produce a corresponding real-time operating system. The data transfer method between the real-time application and the real-time information management system is also automatically set.

Also, real-time applications designed using authoring tools can be re-edited and reused. In other words, it enables production operations without designers programming real-time applications without limiting genres. It is especially useful for producing real-time data broadcasts such as weather forecasts, traffic information, and news tickers.
