Display apparatus and peripheral device signal switching method

A peripheral device signal switching method for use in a display apparatus that is provided with;

• an internal computer,
• a display that displays a video based on a video signal being input,
• a peripheral device connector including a peripheral device connection port to which a peripheral device is connected, and
• an external computer device connector to which an external computer device is connected,
• the peripheral device signal switching method comprising:
• selecting and switching, by a video signal switcher, an input source of the video signal to be input to the display between the internal computer and the external computer device;
• determining, by a determiner, whether the peripheral device connection port is in data communication;
• and
• selecting and switching, by a peripheral device signal switcher, a data communication destination of the peripheral device connector between the internal computer and the external computer device in conjunction with switching of the input source of the video signal in such a manner that the data communication destination of the peripheral device connector becomes identical to the input source of the video signal in a case that the switching of the input source of the video signal is performed, wherein
• selecting and switching the data communication destination of the peripheral device connector comprises:
• in a case that the peripheral device connection port is determined to be in the data communication suspending switching of the data communication destination of the peripheral device connector without switching the data communication destination of the peripheral device connector in conjunction with switching in the video signal switching, and
• in a case that the switching of the data communication destination of the peripheral device connector by the peripheral device signal switcher is suspended, performing the suspended switching of the data communication destination of the peripheral device connector by the peripheral device signal switcher at a time when the peripheral device connection port is determined to be no longer in the data communication.
