As shown in FIG. 1, the apparatus for providing a news package service according to the present invention includes an RSS collector 130, an RSS manager 140, and a metadata service machine 150. Here, the RSS collector may include a storage for storing content and metadata, and may have a separate content and metadata storage (content and metadata DB).

News package service providing apparatus 100 receives a variety of news in the RSS format from one or more RSS provider 110. The RSS provider 110 here will usually be a web content provider over a network.

One embodiment of an RSS format provided by the RSS provider 110 may include a title (title), a link (URL information), a description (short description), an item title (title), a link (URL information), and a description (short description). It consists of a description, author, category, comments (relevant URL), enclosure (media information to add), guid (identifier), pubDate (issue date), and source (source).

The RSS manager 140 sets a collection condition in which the RSS collector 130 collects RSS data from the RSS provider 110 and provides the condition to the RSS collector 130.

Another important function of the RSS manager 140 is to search, inquire, delete or classify the RSS data collected and stored by the RSS collector using the set condition.

The RSS collector 130 collects RSS data from the RSS service provider 110. At this time, the collecting condition is provided from the RSS manager 140, and the condition may be, for example, a keyword set by a user. In addition, RSS data collection may have a periodicity that occurs every specific time according to user needs.

The RSS collector 130 collects RSS data in the RSS format as described above and converts the collected RSS data into TV-Anytime (TVA) metadata. And generate and store a news package based on the TVA metadata.

The generated news package is consumed by the external RSS consumption tool 120 through the metadata service device 150.

Hereinafter, each part of the news package service providing apparatus 100 will be described in more detail with reference to the drawings.

In FIG. 2, the RSS collector 130 included in the news package service providing apparatus 100 is illustrated in more detail.

As illustrated in FIG. 2, the RSS collector includes an RSS data collector 131, an XML parser 133, a TVA metadata generator 135, and a content and metadata storage 137.

The content and metadata storage unit 137 may be configured as a separate device from the RSS collector 130. That is, it may be embedded in the RSS collector, or may exist separately outside the RSS collector.

The RSS data collector 131 collects RSS data from the RSS service provider 110. The collected extensible markup language (“XML”) of the RSS data is passed to an XML parser, where parsing is performed.

The TVA metadata generator 135 converts RSS data into TVA metadata through the result of the XML parser. This process will be explained in more detail later. The converted TVA metadata is stored in the content and metadata storage unit 137.

Finally, the content and metadata storage unit 137 performs the function of storing the content and the metadata, and specifically, a function of generating a news package by the generated TVA metadata and downloading it to the metadata service machine 150. Do this.

3 is a diagram illustrating in detail the RSS manager 140 in the news package service providing apparatus 100.

The RSS manager 140 includes a condition setting unit 141, a metadata manager 143, and a news package classification unit 145.

As described above, in the condition setting unit 141, the user sets a condition to be used for RSS data collection. Conditions that can be set here may include a genre and a keyword.

The metadata manager 143 is responsible for searching, inquiring or deleting TVA metadata collected and stored by the RSS collector 130.

The news package classification unit 145 is responsible for classifying the news package for the news package service to be provided to the user through the metadata service device 150. In this case, the news packages may be classified by recommendation news such as hot news, popular news, and special news, and by genre news such as politics, economy, and society.

FIG. 4A illustrates a metadata service device 150 that is part of the news package service providing apparatus 100 in more detail. In particular, FIG. 4A illustrates a case in which the metadata service device is a bidirectional metadata service device.

The bidirectional metadata service unit 1510 may include a SOAP transceiver 1511, a user request / response manager 1513, a log-in processor 1515, and a user request / response processor 1517. It consists of.

The SOAP transceiver 1511 is in charge of SOAP Encapsulation / Decapsulation for transmitting and receiving SOAP-based messages, and becomes a final or initial repository of SOAP messages (header / body) to be transmitted / received.

The user request / response manager 1513 receives the SOAP message (header / body) from the previous SOAP transceiver 1511, and transmits the SOAP header information to the log-in processor 1515, and the SOAP body receives the user request / response. Transfer to processing unit 1517.

The login processor 1515 queries the content and metadata storage 137 for the user information parsed from the SOAP header, determines whether to log in, and transmits the result to the user request / response manager 1513.

The user request / response processor 1517 parses the SOAP body to obtain parameters for the user request. After generating the SQL query statement to get the result desired by the user from the content and metadata storage unit 137 using the corresponding parameter, query the content and metadata storage unit 137 to generate the XML document as the query result. This is transmitted to the user request / response management unit 153.

In detail, the function of the user request / response processor 157 may be used to deliver items for news packages that the user wants to inquire through the RSS consumption tool 120. That is, by analyzing the items for the news packages to be viewed in the RSS consumption tool, retrieve the corresponding news packages from the content and metadata storage unit 137, and deliver the retrieved news package list to the RSS consumption tool 120 Can be.

In addition, the RSS consumption tool 120 searches for the content and metadata storage unit 137 using a content reference identifier (CRID) of a news package or AV content transmitted by the RSS consumption tool 120 to determine the location of the news package or AV content. You could also pass it on.

4B is a diagram illustrating a case where the metadata service machine is unidirectional.

The unidirectional metadata servicer 1520 illustrated in FIG. 4B includes an XML generator 1521, an encoder 1523, an encapsulator 1525, a resumer 1527, and an RF signal transmitter 1529.

First, the XML generator 1521 retrieves package metadata stored from the content and metadata storage of the RSS collector 130 and prepares an XML document to be transmitted from the metadata.

The created XML document is encoded in TeM or BiM by encoder 1523. Such encoded files are encapsulated into MPEG-2 data carousel or object carousel by an encapsulator 1525. The encapsulator will now output the metadata MPEG-2 TS.

The remuxer 1527 muxes the output metadata MPEG-2 TS with the MPEG-2 TS configured with the AV signal. This is a natural procedure because the metadata MPEG-2 TS is not transmitted alone but must be transmitted muxed with the MPEG-2 TS composed of the AV signal of the existing broadcast channel.

It is now necessary to convert the AV / metadata MPEG-2 TS, which is the output of the remuxer 1527, into an RF signal. This is the RF signal transmitter 1529 is in charge and finally sent to the RSS consumption tool 120.

5 is a detailed block diagram of the RSS consumption tool device 120.

The RSS consumption tool device according to the present invention is composed of a SOAP transceiver 121, an XML parser and generator 123, a news package inquiry unit 125, and a news package consumption unit 127. If the metadata service device is one-way, the SOAP transceiver 121 may be a one-way transceiver.

The unidirectional transceiver 121 extracts the package metadata XML from the RF signal received from the (unidirectional) metadata service 150 in the reverse order of the operation order of the unidirectional metadata service.

If the metadata service device 150 is bidirectional, the SOAP transceiver 121 used to access the metadata service device 150 via SOAP delivers an XML document storing a setting value for a news package inquiry, or Function to import news packages.

The news package inquiry unit 125 recommends a news package from the metadata service machine 150 (recommend news (hot news, popular news, special news)), comprehensive news (news by genre such as politics, economy, society), and search news (keywords). Searched news) and outputs a list of searched news packages on the screen.

In addition, the CRID information of the package selected by the user in the news package list may be transmitted to the metadata service device 150 to confirm the location information of the news package, thereby obtaining the corresponding package.

The XML interpreting and generating unit 123 generates a setting value for the news package selected by the user through the news package inquiry unit 125 as an XML document, or a news package obtained through a unidirectional transceiver or a SOAP transceiver 121. Provides the ability to parse

The news package consuming unit 127 imports through the SOAP transceiver or unidirectional transceiver 123, and uses the news script and AV content of the news package to consume the interpreted news package through the XML parser and generator 125. It has the function of acquiring and providing it through the user screen.

6 is a flowchart illustrating a method of providing a TVA metadata-based news package service collected from RSS according to the present invention.

TVA metadata-based news package service providing method collected from the RSS according to the present invention comprises: a search condition registration step (S610) of first registering RSS conditions; RSS data collection step (S620) of collecting RSS data by using the RSS search condition; A storage step of converting the collected RSS data into TVA metadata, generating a news package based on the TVA metadata, and storing the news package in the content and metadata DB (S630); A management step (S640) of searching, inquiring, deleting or classifying the stored news package; A list providing step of searching for the managed news package by a metadata service and providing a list of news packages to an external RSS consumption tool (S650); And a transmission step (S66) of transmitting the news package requested by the RSS consumption tool through the metadata service.

In the search condition registration step (S610), as described above, the genre and the keyword may be used as the search condition.

Next, RSS data is collected using the RSS search condition (S620). At this time, RSS data may be periodically collected according to a schedule set by a user. In addition, RSS data can be collected by passing the RSS search condition to the http get function argument of the news providing site.

The next step is to convert the collected RSS data into TVA metadata, generate a news package based on the TVA metadata, and store the news package in the content and metadata DB.

This step includes three subdivided steps again as shown in the flowchart shown in FIG.

First, the representative image of the news package and the AV content constituting the news package are found from the collected RSS data and stored in the content and metadata DB (S631).

Step S631 needs more detailed description, which is referred to FIG. 8. In step S6311, first, location information such as a URL of an individual news item is checked from the collected RSS data. Thereafter, an HTML document for an individual news item is obtained from the location information (S6313). In this HTML document, location information such as, for example, the URL of AV content, which constitutes a news package is present. Using the location information, the AV content is stored in the content and metadata DB (S6315). Next, the representative image location information of the news package is extracted from the same HTML document. And the representative image obtained through this is stored in the content and metadata DB (S6317). Finally, a news scripter constituting the news package is also obtained from the same HTML document (S6319).

Reference is again made to FIG. 7. The second step S633 generates a news package using the AV content and the news script constituting the previously stored news package, and stores the news package in the content and metadata DB. More specifically, a CRID of a news package and AV content constituting the news package is generated, respectively. Then, a news package is generated using the news scripter obtained from each CRID and content and metadata DB.

In a third step S635, the active metadata of the news package and the location information of the news package and the AV content constituting the news package are stored in the content and metadata DB.

The attractive metadata may be program information or program location information or a combination thereof.

The S630 step has been described above. Referring back to the overall flow diagram of FIG. 6, the news packages are now stored in the content and metadata DBs, and in order to be prepared to provide such a list of news packages upon request by an external RSS consumption tool, the searched news packages may be retrieved, In step S640 of inquiring, deleting or classifying and managing.

According to the above procedure, when the metadata service is ready to provide the news package service, the user can search the news package by recommending, synthesizing, and searching news through the RSS consumption tool, and lists the news packages by the item from the metadata service. The transmission is received (S650).

According to the above steps, the procedure of collecting RSS data, converting metadata, and transmitting the news package list for consuming the news package to the RSS consuming tool is completed.

On the other hand, the RSS consumption tool, the following steps to receive the desired news package. As a matter of course, the news package acquisition in the RSS consuming tool will follow the above procedure.

9 is a flowchart illustrating this time series news package acquisition step. In order to continue from the step of Figure 6 it is indicated by the following sequence.

First, in step S660, the RSS consumption tool inquires the news package list from the metadata service.

Fig. 10 shows this step in detail. The user selects a desired news package from the list (S661), checks the location information of the package from the metadata service using the CRID of the corresponding package (S663), and acquires the news package (S665).

Next, step S670 of FIG. 9 is performed. The details of identifying the news scripter and obtaining AV content are described in FIG. The RSS consumption tool parses the acquired news package (S671) to confirm the AV content and the news scripter constituting the package (S673), and confirms the location information of the AV content from the metadata service using the CRID of the AV content (S675). ) To acquire the AV content (S677).

The news package thus obtained is consumed through a user interface such as a display device in the RSS consumption tool (S680).

FIG. 12 shows how the steps in FIG. 6 operate in time series with each associated device shown in FIG. 1.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. This process is not described in detail anymore because it can be easily carried out by those of ordinary skill in the art.
