Embodiment Construction

[0016] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0017] figure 1 is a flowchart schematically illustrating the process of generating a test flow according to the present invention. Generally, the method for generating test streams according to the present invention is implemented in the following manner. First, receive requirements related to digital TV broadcasting standards, testing and broadcasting. From this point on, based on the requirements, an appropriate process is selected, and by applying the process, predetermined data are generated. Next, an intermediate product of XML file type is generated so that the user can confirm its relevant value, and the product is converted into a hexadecimal type transport stream to provide the transport stream as a final product. Meanwhile, since there are various digital TV broadcasting standards such as terrestrial broadcasting sta...

Abstract

A method and apparatus for generating a test stream wherein tests of digital TV software at various levels and various digital broadcast standards can be supported. The apparatus includes a data generator module (230) for generating test data by referring to a database based on demands of a user, a data writer module (240) for fetching the test data generated by the data generator module and writing the fetched test data into a text or XML data, a data transformation module (250) for transforming the written text or XML data into a transport stream, and a database (260) in which information needed for the modules to perform their own functions is stored and from which the stored information is fetched. The method of invention may similarly follow the functions of the apparatus.

Description

technical field [0001] The present invention relates to a method and apparatus for automatically generating test data, and more particularly, to a method and apparatus for generating test streams, wherein testing of digital TV software at various levels and various digital broadcasting standards can be supported . Background technique [0002] Korean Patent Laid-Open Application No. 10-2002-0032215 (Korean Patent Application No. 10-2000-0063253) discloses that test data can be automatically generated for testing DASE (Digital TV Application Software Environment) without performing any manual operations Systematic apparatus and methods. However, although this related art apparatus and method can be applied to the test of the DASE system, it cannot generate a transport stream, it can only generate data limited to the DASE standard as a terrestrial broadcast receiving system. In addition, due to being in script file format, the final product does not have a format directly ap...
