Abstract
The present invention relates to a signal processing system, and proposes the switching operation of device selection which is naturally performed for a user. The signal input device 5 comprises a registration means for registering the signal output devices 3, 4, and an establishment means for, when an establishment request signal requesting the establishment of a signal path is sent from any signal output device 3, 4 out of a plurality of the signal output devices 3, 4, judging whether the signal output device 3, 4, which sent the establishment request signal, is registered in the signal input device 5, and establishing the signal path between the signal output device 3, 4 and the signal input device 5 depending on the judged result, thereby avoiding unnatural operation which is not performed in accordance with user operation, thus making it possible to perform the switching operation of device selection which is naturally performed for a user.
