<p>A display system includes a host that provides digital data, and a display that processes and displays the digital data, wherein the host and display are connected by connectors. The connectors generate a sensing signal that differs according to whether the host and the display are connected or disconnected. A host controller determines whether the display is authenticated by high-bandwidth digital content protection (HDCP), interrupts a digital data transmission when an HDCP authentication error occurs, and restarts the digital data transmission upon determining that the display changes to a connection state from a disconnection state based on the sensing signal. A display controller outputs the sensing signal to allow the host controller to determine a state of the display is as if the display is changed to a connection state from a disconnection state, when the display is in an error state causing the HDCP authentication error.</p> |
