step one: firstly, judging whether a display signal is input into a display;
step two: if the display has display signal input, lighting the display picture; then switching the USB2.0 channel to be consistent with a signal source of display signal input; if no display signal is input, the display enters a standby state; returning to the first step when in the standby state;
step three: after switching the USB2.0 channel and the signal source of the display signal input are consistent, further judging whether there is a key (for example, a display remote controller or a physical key or a touch key) to switch the USB2.0 operation and judging whether another interface has a display signal input, that is, whether another display signal input is performed.
If there is a button operation to switch USB2.0, then switch USB2.0 and save USB2.0 channel state.
If another display signal is input, continuing to judge whether the display has the multi-picture browsing function (PBP, picture by picture) started; if the display starts the multi-picture browsing function, continuously judging whether the USB switching condition value is met or not; if the USB switching condition value is met, switching USB2.0 and storing the USB2.0 channel state;
if the display does not start the multi-picture browsing function, returning to the step one; if the display has turned on the multi-screen browsing function but the switch USB condition value is not met, return to step one.
In the above process, the meeting of the USB switching condition value is generated by the USB switching sub-process.
