Claim:
1. A dual mode display-port which connects a host device and a display device according to the display-port communication standards proposed by the Video Electronics Standards Association (VESA), the dual mode display-port connector comprising: a host-side auxiliary interface connected to auxiliary signal terminals of the host device; a display-side auxiliary interface connected to auxiliary signal terminals of the display device; and a cable for connecting the host-side auxiliary interface and the display-side auxiliary interface, wherein the host-side auxiliary interface comprises: a bi-directional converter for converting differential auxiliary signals received via one side thereof into a single auxiliary signal and a single auxiliary signal received via another side thereof into differential auxiliary signals; a direct-current (DC) balancing codec for performing DC balancing encoding on a single auxiliary signal received via one side thereof, and decoding an encoded single auxiliary signal obtained through an encoding process and received via another side thereof; and a bus switch for connecting common signal lines to which differential auxiliary signals or inter-integrated circuit (I 2 C) signals are supplied to differential auxiliary signal lines or I 2 C signal lines, wherein, in the host-side auxiliary interface, the common signal lines are drawn from the auxiliary signal terminals of the host device and connected to the bus switch, and wherein the host-side auxiliary interface further comprises: a first electrophotic converter; a photoelectric converter; and a second electrophotic converter, and wherein, when the I
