Automated apparatus and method for producing a bus-controlled television

Abstract

An automated apparatus for producing and testing a bus-controlled television includes a camera, a bus control facility, an automatic connector, and a remote controller. The camera photographs a predetermined area near the automated apparatus and outputs an approach detection signal indicating if the television is located in such area. Also, the camera photographs the screen of the television when it is in the predetermined area and outputs a screen state signal which represents the information displayed on the screen. The bus control facility generates a television test signal based on the approach detection signal and transmits remote control signals to the television to select control items for testing various functions of the television. The automatic connector connects the television and the bus control facility when the television is located in the predetermined area to enable the bus control facility to transmit the television test signal to the television. The remote controller inputs the remote control signals from the bus control facility and transmits corresponding remote control signals to the television for controlling the various functions of the television. As the various functions are being performed, the camera photographs the screen and outputs corresponding screen state signals, and the bus control facility can determine if the data of the control items are correct and if the television is properly functioning based on the screen state signals output from the camera.
