Display apparatus and peripheral device signal switching method
A display apparatus comprises a peripheral device signal switcher that selects and switches a data communication destination of a peripheral device connector between an internal computer and an external computer device in conjunction with switching of an input source of a video signal by a video signal switcher in such a way that a data communication destination of the peripheral device connector becomes identical to the input source of the video signal, in a case where switching of the input source of the video signal by the video signal switcher is performed, wherein the peripheral device signal switcher suspends 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 by the peripheral device signal switcher, in a case where a discriminator discriminates that a peripheral device connection port is in data communication.
1 . A display apparatus comprising:
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;
an external computer device connector to which an external computer device is connected;
a video signal switcher that selects and switches an input source of the video signal to be input to the display between the internal computer and the external computer device;
a determiner that determines whether the peripheral device port is in data communication; and
a peripheral device signal switcher that selects and switches 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 by the video signal switcher 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 by the video signal switcher, wherein:
the peripheral device signal switcher suspends 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, by the peripheral device signal switcher, in a case that the determiner determines that the peripheral device connection port is in the data communication, 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, the peripheral device signal switcher performs the suspended switching of the data communication destination of the peripheral device connector at a time when the determiner determines that the peripheral device connection port is no longer in the data communication.
2 . The display apparatus according to claim 1 , wherein
in a case that the switching of the data communication destination of the peripheral device connector by the peripheral device signal switcher is suspended, the peripheral device signal switcher causes the display to display an indication that the switching of the data communication destination of the peripheral device connector is suspended.
3 . The display apparatus according to claim 1 , wherein
in a data stored in the peripheral device is accessed by the internal computer or the external computer device via the peripheral device connection port, the determiner determines that the peripheral device connection port is in the data communication.
4 . The display apparatus according to claim 1 , wherein
in a case that data stored in an internal storage medium of the peripheral device is rewritten by the internal computer or the external computer device via the peripheral device connection port, the determiner determines that the peripheral device connection port is in the data communication.
5 . The display apparatus according to claim 1 , wherein
in a case that video or audio communication is performed between the internal computer, or the external computer device, and the peripheral device via the peripheral device connection port, the determiner determines that the peripheral device connection port is in the data communication.
6 . The display apparatus according to claim 1 , wherein
the peripheral device is a touch input device including a touch sensor.
7 . 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.
