Signal processing device and control method, signal processing method, program, and signal processing system

A control method for a signal processing device that controls a plurality of signal processing units that process an input signal inputted via a signal line with wide bandwidth, via a control line with narrow bandwidth or the signal line, comprising the steps of:

• storing correspondence information that associates instruction information indicating an instruction of control with respect to each of the signal processing units, with control information related to all of the plurality of signal processing units, among pieces of control information necessary for each of the signal processing units to execute content of control;
• and
• transmitting the control information associated with the instruction information by the correspondence information, to the plurality of signal processing units via the signal line, when control is instructed with respect to the plurality of signal processing units.

A program for causing a computer to execute a process of controlling a signal processing device that controls a plurality of signal processing units that process an input signal inputted via a signal line with wide bandwidth, via a control line with narrow bandwidth or the signal line, the process including the steps of:

• storing correspondence information that associates instruction information indicating an instruction of control with respect to each of the signal processing units, with control information related to all of the plurality of signal processing units, among pieces of control information necessary for each of the signal processing units to execute content of control;
• and
• transmitting the control information associated with the instruction information by the correspondence information, to the plurality of signal processing units via the signal line, when control is instructed with respect to the plurality of signal processing units.

A signal processing device which has a signal processing unit that processes an input signal inputted via a signal line with wide bandwidth, the signal processing unit being controlled by a control unit via a control line with narrow bandwidth or the signal line, comprising:
