摘要： An apparatus for automatically performing channel change of a television receiver using a video cassette recorder includes a playback command detector for detecting a playback command, a channel sensor for sensing a video viewable channel which is selected by a radio frequency changeover switch according to a user's selection, a memory for storing the video viewable channel sensed by the channel sensor, television receiver channel change data and television receiver codes corresponding to different types of the television receiver, a controller for reading one of the television receiver channel change data stored in the memory corresponding to the video viewable channel sensed by the channel sensor upon the detection of the playback command by the playback command detector, and a remote transmitter for remotely transmitting the television receiver channel change data from the controller to the television receiver to change a current channel of the television receiver to the video viewable channel sensed by the channel sensor in a playback mode of the video cassette recorder. According to the invention, the current channel of the television receiver can automatically be changed to the video viewable channel upon input of a playback key signal or insertion of a video tape into a deck of the video cassette recorder.

摘要： An apparatus for adjusting a horizontal position of a video display appliance in which a display image is put in the center of a monitor screen. The apparatus includes a comparative circuit, a horizontal correction circuit and a deflection circuit. The comparative circuit detects an overlap signal representing that a horizontal flyback pulse and a video signal are overlapped. The horizontal correction circuit calculates a mean value of first and second horizontal values and transmits the mean value to the deflection circuit. The deflection circuit adjusts the horizontal position using the mean value as an adjustment value to put the display image in the middle of the monitor screen.
