ABSTRACT:
A control apparatus and method for processing a signal, and more particularly, a control apparatus and method for preventing a signal from being processed repeatedly by transmitting and receiving information related to a signal processing in a composite signal processing system that contains a television and a peripheral device. A signal providing device transmits enhancer information related to the signal processing by means of a wired or wireless communication. A signal receiving device uses the enhancer information and controls a signal processing block. Therefore, since the signal receiving device prevents the enhancer signal from being processed repeatedly, distortion of the signal can be avoided and an optimum signal can be output.
