LONG DISTANCE TRANSMISSION SYSTEM OF HDMI OR DVI SIGNAL

摘要

PURPOSE: A long distance transmission system of a high definition multimedia interface (HDMI) or a digital video interface (DVI) signal is provided to output a normal HDMI or DVI signal by forming a signal restoration part doubly and sensing the abnormality of the HDMI or DVI signal, thereby improving the security and the stability in the transmission of the HDMI or the DVI signal. CONSTITUTION: A signal restoration part (20) modulates and demodulates an HDMI or a DVI signal transmitted from a signal generator (10) and restores to an original signal. A signal output part (30) receives the HDMI or the DVI signal transmitted from the signal restoration part and outputs the signal. The signal restoration parts are arranged between the signal generator and the signal output part, restore the HDMI or the DVI signal generated in the signal generator to the original signal without loss, and output the signal at the signal output part.
