Abstract
Disclosed is a signal control method that is characterized by receiving a first signal, a second signal comprising multiple components, component information indicating the relationship between the components, and analysis control information comprising information indicating the relationship between the components and the second signal. The signal control method is further characterized by controlling the first signal or the second signal on the basis of the components and the analysis control information.
