ABSTRACT:
A television receiver has a main body and a remote-control transmitter. A display having an aspect ratio of 16:9 visualizes an incoming video signal. A picture analysis circuit is operative for analyzing the incoming video signal. An aspect converting circuit is operative for changing an aspect condition of indication of the incoming video signal on the display. A button is provided on one of the main body and the remote-control transmitter for commanding automatic aspect conversion when being operated. A decision is made as to whether or not the button is operated to command automatic aspect conversion. When the button is decided to be operated, the picture analysis circuit is activated to analyze the incoming video signal and the aspect converting circuit is controlled to automatically control the aspect condition of indication of the incoming video signal on the display in response to a result of the analysis by the picture analysis circuit.
