If the determination is yes, the DP to HDMI port 1032 receives the second video signal S2 , and the process goes to step 86 ; if the determination is no, the process returns to step 82 .

需說明的是，上述步驟83的作用為再次確認該訊號輸入埠102確實還是有接收到該第一影像訊號S1，如此一來，當流程進入步驟85且判斷為否及流程回至步驟82時，可避免該訊號輸入埠102因遭外部因素而未接收到該第一影像訊號S1，導致該影像處理器2無法輸出該第一輸出訊號So1至該顯示器3進行影像顯示的情況發生。It should be noted that the function of the above step 83 is to reconfirm that the signal input port 102 still receives the first video signal S1.
