ABSTRACT:
An apparatus for testing video ordered type terminals by using a computer, and a testing method therefor, employ a personal computer and a bit stream board of the computer to form a virtual server of an ordered type video terminal testing system, thereby making it easier to test a video terminal. In the conventional apparatus for testing an ordered type video terminal, a server is required in order to test such a terminal. This server includes a memory system of a large capacity and computer capable of carrying out a high speed arithmetic operation. Therefore, its installation and movement are not easy, while its price is very high. Accordingly, it is uneconomical to procure it only for testing purposes. Therefore, the present invention provides an apparatus for testing a video terminal, in which a personal computer, an RS-232C interface normally used in the personal computer, and a bit stream board installed in a slot of the computer are utilized to form a virtual server, thereby making it easy to test a video terminal. The testing system of the present invention is economical, and is not restricted by time and place compared with the case of using the expensive server.
