Abstract
Emulating human faculties of sight, image, and hand control by a testing system to interact with a multimedia switching system. The testing system can control a multimedia video unit by the transmission of infrared command signals emulating a user actuating buttons on a hand-held infrared transmitter unit to verify that the system responds correctly to such actuations. Also, the testing system can analyze quality of images to be transmitted, transmit those images through the switching system via user multimedia video units, receive those signals at other user multimedia video units, and analyze the quality of the resulting video images. Further, the testing system can place varying levels of multimedia traffic through the multimedia switching system. Further, the testing system can test call control performed by the multimedia switching system by utilizing an infrared transmitter unit to place and receive calls. The multimedia switching system utilizes text that is displayed on the multimedia video units to indicate call state. The testing system identifies the text that is being displayed at different states of the call and determines if the multimedia switching system is functioning properly.
