The present invention relates to an apparatus and a method for testing a data broadcast receiver, and more particularly, to test a data broadcast receiver capable of performing an automated test of an advanced case requiring user verification during a data broadcast function test. An apparatus and method are provided.

Recently, as the demand for digital television expands, digital broadcasting of high quality and high quality through various broadcasting media such as terrestrial broadcasting, satellite broadcasting, and cable broadcasting has started.

In addition, each broadcaster and cable broadcaster is introducing a data broadcast service that can provide a variety of additional information with the broadcast program.

Data broadcasting is an end-to-end interactive personalized solution that provides not only information related to broadcasting programs other than the existing broadcasting programs, but also living information such as weather, news, and traffic information, as well as internet and e-commerce services through a broadcasting network. ).

That is, the broadcasting station provides additional data contents together with the broadcasting program, and the data broadcasting receiving apparatus and the broadcasting station can interact with each other through the data contents, so that the information desired by the user can be obtained more widely.

For example, a user may check a character or a time background while watching a history program, and may also check personal data of a favorite singer or a player while watching an entertainment program or a sports program.

Due to the characteristics of data broadcasting capable of bidirectional communication as described above, the application fields are very diverse, such as entertainment, shopping, sports, education, etc. Therefore, the possibility of the development of data broadcasting services is very high. Accordingly, data broadcasting having a data broadcasting processing function is provided. Development of receivers is actively underway.

On the other hand, the data broadcast receiver must be certified for the data broadcast function.

In order to be certified, the data broadcasting receiver must pass all the tests specified by the relevant institution, and therefore, a thorough test is required at the development stage.

That is, when developing various data broadcasting products, a test is necessary for certification and verification, and an accurate test environment must be provided.

These tests consist of a mix of test cases that can be automatically tested and test cases that test engineers must see for themselves.

If the test is possible automatically, the function is verified by the application itself without user confirmation.

Therefore, there is no problem when the test can be performed automatically by the application itself. However, the test case mainly related to the user interface (UI) can directly check the picture, text, color, etc. drawn on the screen. Should find out.

FIG. 1 is a diagram of a screen of a data broadcasting receiver for performing a test in relation to a user interface according to the prior art. The Milky Way shape that appears throughout the screen is a video screen 10 provided by default. The image to be sprayed is a shape in which a light green rhombus 30 is contained in a white round circle 20.

If these patterns appear on the screen, the test engineer will test against the actual screen.

Therefore, in the prior art, since the test is performed by the intuition of the test engineer, it is difficult to judge the exact position, exact color and shape of the actual test pattern, and there is a limit in informing the developer of the exact result.
