Patent ID: 7694326

Claim:
A signal processing system comprising a first signal processing apparatus for performing predetermined signal processing on an input signal and for outputting the processed signal, wherein said predetermined signal processing includes adaptive processing, and a second signal processing apparatus for supplying a signal to said first signal processing apparatus, said second signal processing apparatus comprising: wired supply means for supplying by wired connection a signal indicating first information to be used in the predetermined signal processing of said first signal processing apparatus to said first signal processing apparatus, wherein said first information includes first resolution-creating coefficients that replace default resolution-creating coefficients during said adaptive processing upon said first signal processing apparatus receiving said first resolution- creating coefficients from said second signal processing apparatus via said wired supply means when an instruction signal is not received by said first signal processing apparatus and said second signal processing apparatus is installed in relation to said first signal processing apparatus, and wherein the default resolution-creating coefficients are utilized by said first signal processing apparatus when said second signal processing apparatus is not installed in relation to said first signal processing apparatus; and wireless supply means for wirelessly supplying a signal indicating second information for changing a function of the predetermined signal processing of said first signal processing apparatus to said first signal processing apparatus, said second information wirelessly supplied upon said first signal processing apparatus receiving said instruction signal, wherein said second information includes second resolution-creating coefficients that replace said first resolution-creating coefficients during said adaptive processing, the second resolution-creating coefficients being upgraded from said first resolution-creating coefficients.
