Abstract: A system for projecting a displayed image of an electronic device through networking, applied to a conference room having at least one Wi-Fi AP, includes at least one electronic device, at least one USB flash drive and a receiving module. The electronic device further has a screen, a wireless network module and an identity. The USB flash drive is to store a pairing information and a network projection software. The receiving module further has an IP address. When the USB flash drive is connected with the electronic device, the electronic device captures the pairing information and uses the wireless network module to couple the at least one Wi-Fi AP, the electronic device further uses the pairing information to login the IP address of the receiving module, and then the electronic device uses the network projection software to output the displayed image to the receiving module.

Abstract: A remote control method comprises: providing a receiving device electrically connected with a display device; the receiving device establishing wireless communication connections respectively with a mobile internet device and a computer; a user inputting a control instruction to the mobile internet device to transmit the control instruction to the receiving device therefrom; the receiving device forwarding the control instruction to the computer; and the computer responding to the control instruction and transmitting a screen frame to the receiving device for the display device to output the screen frame. The remote control method may simplify the operating procedures for switching computers and enhance the communication quality between the mobile internet device and the computer.

Abstract: A method of establishing a paid connection using a screen mirroring application between multi-platforms is disclosed. A transmitting end application is installed in a transmitting end apparatus of a sharing source. A receiving end application is installed in a receiving end apparatus of a sharing target. If the transmitting end application is a paid version, an unlimited connection is established for performing screen mirroring between the transmitting end apparatus and any receiving end apparatus. If the transmitting end application is a free version, the method further confirms if the receiving end application is a paid version for deciding whether a limited connection or an unlimited connection should be established. Thus, it is assured that either the transmitting end application or the receiving end application is a paid version, the interests of application developers are protected and users are free from paying twice for establishing one connection.

Abstract: A sender device of sharing screenshots comprises a detection module, a control module and a wireless network interface. The detection module detects in the background whether a user is executing a screenshot activity and outputs a corresponding trigger signal. The control module electrically connects with the detection module and retrieves a latest-taken screenshot according to the trigger signal output by the detection module. The wireless network interface electrically connects the control module for establishing a wireless network link with a receiver device and transmitting the screenshot to the receiver device. The abovementioned sender device is able to simplify the operation to share screenshots.
