Abstract

A video tuner capable of changing TV channels directly in conjunction with a TV set and/or capable of changing satellite channels with may be received from a satellite antenna (1). The device overcomes the problem that in the past a separate tuner has been required to change the signal/polarity of a carrier signal from a satellite antenna and a further tuner (7) and remote control (7a) have been required to change TV channels. The device in a preferred embodiment is in the form of a plug-in chip or dedicated circuit, also overcomes a problem of having large amounts of wiring when there are more than one satellite receiver. Power supplies taken from an internal bus within a conventional receiver and control signals are provided from an existing micro-processor (18). <IMAGE>
