1. A multi-view virtual display signal processing method, comprising:
in a state that at least two view signals of a predetermined frequency are received, synchronously processing the at least two view signals to form a multi-view video signal and a multi-channel audio signal, and outputting the two signals; and
forming, according to the multi-view video signal, a first-type control signal matching the multi-view video signal and outputting the first-type control signal;
wherein the first-type control signal is a pulse signal delayed by a delay time within which sorting of the multi-view video signal is completed, and
in a high level state of the pulse signal, a time-sharing operation is performed to respectively control different external devices that provide the at least two view signals, in different parts of duration of the high level state.
