Patent ID: 7639919

Claim:
A signal processing system comprising: a network; a signal outputting device connected to said network; and a signal inputting device connected to said network; said signal outputting device having sending means for sending signal path change information representing a change in a signal path in said signal outputting device to said signal inputting device when the signal path in said signal outputting device is changed; said signal inputting device having changing means for adaptively changing a signal path between said signal outputting device and said signal inputting device based on said signal path change information, said inputting device further comprising: first receiving means for receiving a signal path change information including an output plug information sent from said signal outputting device; sending means for sending a request for checking a status of said signal outputting device thereto; second receiving means for receiving a result of checking the status of said signal outputting device; and said changing means comprises means for adaptively changing the signal path between said signal outputting device and said signal inputting device based on the result of checking the status of said signal outputting device and wherein said changing means comprises means for changing said signal path based on whether a PtoP connection and a Bin connection are established or not, wherein when the outputting device is in a virtual output status the outputting device sends the signal path change information to the signal inputting device and does not send a disconnect signal to the signal inputting device.
