LONG-DISTANCE TRANSMISSION APPARATUS OF HIGH QUALITY DIGITAL(HD TYPE VIDEO) IMAGE SIGNAL USING THE UNSHIELDED TWISTED-PAIR CABLE

摘要

The present invention relates to a long-distance transmission apparatus of a high quality digital (HD image) image signal using an unshielded twisted-pair (UTP) cable which is capable of: improving piping space efficiency for piping a cable by using the UTP cable having a relatively smaller diameter than a coaxial cable, during long-distance transmission of the high quality digital (HD image) image signal; and outputting the high quality digital (HD image) image signal, captured by a HD camera, through the UTP cable without using an additional power line or signal line.
