INTERFACE APPARATUS CONNECTED WITH ELECTRONIC DEVICE

摘要

An interface apparatus is capable of connecting with a plurality of external devices and an electronic device. The electronic device generates control signals and a selecting signal. The interface apparatus comprises a plurality of interface ports, an interface, a selection unit, and a switch. The interface ports connect with the external devices respectively. The interface controls the switch to establish a connection between the selection unit and the interface in response to the first control signal for transmitting the selecting signal to the selection unit. The selection unit selects the interface port corresponding to the selecting signal to connect with the switch. The interface further transmits information from the external device corresponding to the selected interface port to the electronic device through the switch and the interface in that order in response to the second control signal.
