The present invention relates to a data broadcasting retrieval apparatus and a method of operating the same, which enables a digital broadcasting receiver to efficiently search and view a data broadcasting application using a browser.

Recently, the modern society is facing the information age due to the remarkable development of the information communication field and the electronic and internet due to the digital revolution, and the spread of information using the wired / wireless media in the conventional spread of information by simple contact. It is also possible to receive the information necessary for themselves in real time.

In recent years, the digitization of television broadcasting which is basically provided in each household is rapidly progressing, and digital television has become a huge and efficient information storage medium and a medium for providing information.

In general, digital television refers to a general term for television broadcasting transmitted digitally. In the United States, we decided to adopt digital for the next generation of televisions called ATV (Advanced television). In Europe, many projects such as HD DIVINE such as Swedish broadcasting, SPECTRE of the UK and DIAMOND of French broadcasting are in progress. Research is being actively conducted in each country in the next generation television system linked with ISDN or computer network.

Meanwhile, a stream transmitted in digital broadcasting may transmit data information together with a video / audio signal. Here, the data information transmitted along with the video / audio signal is based on markup data such as HTML of ATVEF (Advanced Television Enhancement Forum), XDML of Digital TV Application Software Environment (DASE), and Xlet of DASE. Java-based data information.

In preparation for the digital broadcasting, many companies are developing digital televisions or set-top boxes capable of receiving digital broadcasting and data broadcasting, and are expected to receive the most attention when the use of digital television becomes common.

In the digital broadcasting, various additional information is provided to the user by using data broadcasting technology as well as high-definition and high-quality AV (audio / video) broadcasting.

Conventional analog broadcasting can only carry one video in one radio wave, and audio has to be transmitted in another radio wave. However, the above-mentioned digital broadcasting has a quality in addition to the advantage that a plurality of video or audio can be loaded in one radio wave. It is a next-generation broadcasting technology that can operate, reproduce, and accumulate information without compromising information.

As such, when several data broadcasting applications are included and transmitted in one broadcast stream, only one application is executed by the user's selection.

As a method for searching and executing a data broadcasting application transmitted in multiple times as described above, all text information related to the application as well as the title of the data broadcasting application are sequentially provided using an electronic programming guide (EPG).

In this case, users have difficulty in finding the desired application because the user only looks at the information of the provided application and guesses which application.

In other words, since only the title is selected from the list to find the desired application, it is impossible to obtain accurate information about what the application is and what screen configuration is made. Occurs.

In addition, data broadcast and set-top box developers have a burden of developing a new user interface (UI) to provide a user with a convenient data broadcast search interface.

An object of the present invention is to provide a visual and efficient data broadcasting retrieval environment by providing a data broadcasting application transmitted from a digital broadcasting receiver to a user as XML information using an embedded data broadcasting browser.
