[0045] Step S10, when the detection instruction is detected, detect whether there is a signal input to each signal source channel of the multimedia playback device;
[0046] The multimedia playback device detects the detection command in real time. When the multimedia playback device detects the detection command, it detects whether each signal source channel of the multimedia playback device has signal input, so as to confirm which signal source channels have signal input and which signal source channels have no signal. enter. The multimedia playback device does not detect the detection command, does not perform any operation or continues to detect the detection command. In this embodiment, whether there is a signal input to the signal source channel can be determined through the status signal fed back by the signal source channel. For example, when the signal source channel has a signal in...
