LONG-DISTANCE TRANSMISSION APPARATUS OF HIGH QUALITY DIGITAL(HD TYPE VIDEO) IMAGE SIGNAL

摘要

The present invention relates to a long distance transmission device for a digital HD image signal. When the digital HD image signal is transmitted, a digital signal is converted into a signal to be loaded on a UTP cable and then is amplified. The amplified signal is transmitted through the UTP cable. The optimum HD signal modified in FPGA is transmitted to a digital DVR as the digital signal and is reproduced to be displayed on a monitor.
