ABSTRACT:
A wide aspect ratio screen color television system, such as a 16:9 aspect ratio screen television system, includes a signal generating circuit for generating the wide aspect ratio screen color television signal with a predetermined two-dimensional frequency band, a screen separating circuit for separating the color television signal into at least a first television signal relating to a relatively narrow aspect ratio portion and second television signal relating to an excess portion thereover, a circuit for eliminating a prescribed high frequency region of the two-dimensional frequency band of the first television signal, a signal suppressing circuit for suppressing the frequency band of the second television signal and a signal multiplexing circuit for multiplexing the suppressed second television signal onto the two-dimensional high frequency band region in place of the eliminated portion of the first television signal.
