Abstract: Disclosed are a method and an apparatus for automatically testing a data broadcast receiver, so that a sub-system can be constructed with an independent module and a distributed processing can be easy to achieve, in which both an interface between sub-systems and an interface between a test manager and a sub-system are connected by a packet communication scheme using a universalized TCP/IP, test results are collected by means of an uplink return channel of bi-directional channels in an out-of-band channel hold by a broadcasting receiver, a module for generating information on the out-of-band channel is integrally constructed within one test device, a graphic user interface is applied in the Windows environment of the Microsoft corporation, and a scenario including storage of remocon operation and screen state is automatically processed.
