Abstract:
A signal recording method comprising the steps of:splitting the entire area of an input signal into a main area and a plurality of sub-areas;generating a main signal for the main area and a plurality of sub-signals for said sub-areas;setting priority for each of the sub-signals;finding an allowable signal area of the main signal in which noise superimposition does not affect the playback signal of the main signal;sequentially selecting the sub-signals synthesized to said main signal in the sequence of the decreasing priority within the range of the capacity of the allowable signal area; andsynthesizing the selected sub-signal to the allowable signal area of the main signal for recording the main signal to which the sub-signal has been synthesized,wherein the synthesized selected sub-signal is variably scalable during the playback signal of the main signal.
