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. In the method and the apparatus, in a state in which the middleware of a complicated data broadcast receiver has been implemented, personnel expenses can be reduced and test results can be systematically derived.

Claims23

Dependent claims

An automated testing method for a data broadcast receiver by using a test application, various channel configuration information according to the test application, and scenario information, the method comprising the steps of:

(a) setting a test scenario according to a test application program and a test sequence which are suitable for a test-targeted device by using the test application;
(b) checking communication connection between the test manager and a sub-system for securing physical communication channels to the sub-system, initializing internal hardware, internal state information and communication matching of the sub-system when the communication connection is checked, and performing an initialization for the test-targeted device by using a test manager;
(c) a transmission manager forming a transport stream, and transmitting the transport stream to the test-targeted device in response to a command from the test manager, starting a return time count for receiving test result values from a time point at which an interactor has transferred downloading confirmation signals of the transport stream to the test manager;
(d) transmitting IR signals suitable for the test-targeted device at a reset and remocon controller, if it is necessary to input remocon signals to the test-targeted device;
(e) initializing the test-targeted device if it is necessary to reset the test-targeted device;
(f) stopping the test if it is necessary to stop a test momentarily;
(g) commanding the transmission manager to stop the transport stream and terminating the test, if the test starts according to test types and the test result values are not transmitted to the test manager even after return time lapses;
(h) transmitting the test result values to the test manager through the interactor, and reporting the termination of the test if the test is normally terminated;
(i) storing the test result values in the media storage unit if the test result values correspond to video displayed on a screen or audio;
(j) determining whether residual tests exist in the scenario if the interactor notifies the test manager of the termination of the test, or if the media storage unit completes the storage of the video or the audio;
and
(k) commanding an initialization of the sub-system, initializing the test-targeted device after the sub-system is initialized, and resuming the test, if the residual tests exist in the scenario.

a transmission manager for processing application programs and channel configuration information as in actual broadcasting environment, both of which are received through the test application;
an interactor for checking download of the test application to a test-targeted device, and transferring information to the test-targeted device during a test;
a media storage unit for storing video or audio output results of test result values;
a reset and remocon controller for initializing the test-targeted device and generating remocon control signals;
a report manager for processing the test result values in a report form and outputting various reports;
