Abstract

A transmission device capable of control feedback comprises a sender and a receiver. The sender electrically connects to an electronic device through USB type-C for receiving an image signal and sending a control signal. A first processing circuit of the sender converts a network packet into the control signal. A first communication circuit of the sender receives the network packet and sends the image signal. The receiver electrically connects to a display device for sending the image signal and receiving the control signal. A second processing circuit of the receiver encapsulates control signal into the network packet. A second communication circuit of the receiver communicably connects to the first communication circuit to send the network packet and receive the image signal.
